Conventional treatments, such as blood transfusions, iron chelation, fetal haemoglobin induction, and allogeneic haematopoietic stem cell transplantation, have improved outcomes but remain limited by treatment-related toxicity, donor availability, and incomplete curative potential. Methods: A narrative literature review was conducted using PubMed up to 2025. Search terms included \"sickle cell disease,\" \"sickle cell anemia,\" \"\u03b2-thalassemia,\" \"transfusion-dependent beta-thalassemia,\" \"gene therapy,\" \"gene addition,\" \"gene editing,\" \"CRISPR-Cas9,\" \"lentiviral vector,\" \"children,\" \"paediatric,\" and \"pediatric.\" Relevant clinical trials, reviews, consensus statements, and guidelines were selected and qualitatively analysed. Results: Gene therapy for \u03b2-haemoglobinopathies is based mainly on two strategies: gene addition and gene editing. Gene addition uses lentiviral vectors to introduce functional or modified \u03b2-globin genes into autologous haematopoietic stem cells, whereas gene editing targets regulatory pathways, particularly BCL11A, to reactivate fetal haemoglobin synthesis or correct disease-causing mutations. Clinical studies have shown encouraging outcomes, including transfusion independence in many patients with \u03b2-thalassaemia and marked reduction or elimination of vaso-occlusive crises in sickle cell disease. Paediatric and adolescent data are increasingly promising, although still limited. Conclusions: Gene therapy is reshaping the treatment landscape of \u03b2-haemoglobinopathies by offering a personalised and potentially curative approach. However, long-term safety, conditioning toxicity, fertility preservation, accessibility, costs, and implementation in high-prevalence regions remain critical challenges. Further studies are needed to optimise patient selection and expand equitable access."

From the groundbreaking research, the ultimate battle of the prizes and patents to a number of books, the science of CRISPR continues to be significant in the biomedical field. For many decades now, the emergence of synthetic biology as an intervention to correct diseases has become the foundation of biomedical research. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based genetic editing has become a common place for routine investigation of scientific hypotheses in pre-clinical settings. More recently, CRISPR-based diagnostic testing kits for SARS-CoV-2 have showcased a translational output. Furthermore, a technological landmark was achieved when the Food and Drug Administration (FDA) approved the first CRISPR-based gene therapy (exa-cel) to edit erythroid specific enhancer region of BCL11A in hematopoietic stem cells, introduced in patients suffering from sickle cell anemia to achieve durable remission. In this review, we provide a snapshot into the most important milestones along the journey of CRISPR from its discovery in bacteria to its usage in precision medicine. The intervention of machine learning tools has now intertwined complex biology with high-throughput scalable outputs. Given the vast amount of information on CRISPR, we try to pin down key take-home messages for scientists as well as non-scientist readers. This review article attempts to understand why and how CRISPR remains significant and seamlessly integrates in the emerging era of new technologies."

Ex vivo CRISPR-Cas9 editing of autologous CD34-positive hematopoietic stem and progenitor cells to reactivate fetal hemoglobin has produced durable freedom from severe vaso-occlusive crises in SCD and sustained transfusion independence in TDT. This approach offers a donor-independent alternative to allogeneic hematopoietic stem-cell transplantation without graft rejection or graft-versus-host disease. Hemoglobinopathies, therefore, provide the first clinically validated delivery model for CRISPR therapeutics. Successful implementation, however, requires more than editing efficacy. It depends on structured referral, candidacy assessment, organ function review, mobilization and collection, centralized manufacturing, pharmacokinetic-guided myeloablative conditioning, transplant-level supportive care, fertility preservation, psychosocial support, and prolonged surveillance coordinated among primary hematologists and cellular therapy programs. Key barriers include stem cell collection, conditioning-related toxicity, cost, reimbursement friction, and persistent inequities in access. Long-term follow-up and registry participation are necessary to evaluate outcomes beyond pain crises, identify late toxic effects, and compare real-world effectiveness across gene editing, gene addition, and allogeneic transplantation. In oncology, CRISPR-based therapy remains investigational, with early clinical feasibility demonstrated in relapsed or refractory B-cell malignancies, T-cell malignancies, AML, multiple myeloma, and selected solid tumors. For hematologists, oncologists, and transplant and cellular therapy programs, the central challenge is to integrate CRISPR into practice with the rigor required for any high-risk curative therapy: careful patient selection, disciplined delivery, and long-term accountability."

In combination with induced pluripotent stem cell (hiPSC) reprogramming, in vitro gametogenesis provides an avenue for patient-specific disease modeling approaches. However, further advancements are required, as current protocols are limited to early stages of germ cell development. To get one step closer to this goal, here we aimed to identify optimal conditions for generating high-quality hiPSC lines capable of in vitro germ cell differentiation. We isolated two clinically available somatic cell types, peripheral blood-derived mononuclear cells and cumulus cells from the same female donor, and reprogrammed them into human induced pluripotent stem cells (hiPSCs). We then assessed their differentiation into ectoderm, mesoderm, and endoderm, and evaluated their X-chromosome inactivation status, a critical indicator of stem cell quality. Finally, we compared the capacity of PBMC- and cumulus-derived hiPSCs to differentiate into human primordial germ cell-like cells (hPGCLCs). We found that despite variability between cell lines, hiPSCs from both cell types were capable of generating hPGCLCs and that variations in X-chromosome state did not appear to generally interfere with the process. Our findings provide insight into germ cell differentiation from different clinically available starting materials guiding future patient-specific studies of fertility disorders."

"abstract_text": "ID: 41416641\nTitle: The road to restore male fertility using in vitro-derived germ cells.\nAbstract: Human-induced pluripotent stem cells (hiPSCs) offer immense potential in reproductive medicine, particularly for males who lack germ cells and cannot achieve biological parenthood through conventional ARTs. Early efforts to derive human germ cells from stem cells were hindered by low efficiency, subpar characterization, and the lack of standardized differentiation approaches. However, recent advancements have led to the development of defined protocols that mimic early embryonic development and allow the specification of transcriptomically and epigenetically validated human primordial germ cell-like cells (hPGCLCs). Current research focuses on maturing hPGCLCs in vitro, particularly within 3D culture systems that resemble their physiological microenvironment, with the aim of producing transplantable hiPSC-derived spermatogonial stem cells (SSCs) or differentiating them to sperm. At the same time, researchers are also testing whether hiPSCs generated from infertile patients can resume germline differentiation. This narrative review aimed to summarize the key efforts and remaining challenges in differentiating male germ cells from human pluripotent stem cells (hPSCs), with a particular focus on defined and validated protocols for hPGCLC specification. In parallel, we addressed key safety and ethical considerations that must be accounted for the development of clinical applications. A deeper understanding of the approaching therapeutic use of hiPSCs in reproductive medicine is essential for developing novel regenerative fertility strategies. PubMed, Scopus, and Web of Science were searched for studies attempting germ cell differentiation from hPSCs using relevant keywords ('stem cells', 'human pluripotent stem cells', 'human embryonic stem cells', 'human induced pluripotent stem cells', 'somatic cell reprogramming', 'infertility', 'germline', 'spermatogenesis', 'germ cells', and 'primordial germ cells'). No time period restriction was established. Studies with an exclusive focus on female germline differentiation were excluded. To maintain a human-focused perspective, only key animal studies are presented. The literature reveals a clear segregation among protocols for deriving germ cells from hPSCs, particularly between earlier studies lacking standardized differentiation conditions and characterization, and the most recent, defined protocols having transcriptomic and epigenetic validation against in vivo hPGCs. Moreover, during the last decade, the field has seen remarkable progress, with multiple efforts aimed at maturing hPGCLCs, closely recapitulating late male embryonic germline development. Additionally, hiPSCs derived from male patients at risk of infertility, particularly those without underlying genetic syndromes, generally retain the capacity for early germline commitment. While attempts at maturating patient germ cells beyond the hPGCLC state remain limited, the rapid pace of discovery and refinement in recent years suggests that further breakthroughs, including clinically applicable fertility restoration strategies, are likely to be achieved in the near future. The ability to generate hiPSCs from infertile patients and to specify them into hPGCLCs supports the feasibility of obtaining hiPSC-derived SSCs for future therapeutic use. These advances raise important ethical, regulatory, and societal questions that must be actively discussed among researchers, clinicians, policymakers, and the general public to ensure responsible and equitable access to these technologies.

One of the first embryonic lineages to be specified in the human embryo is the germ cell lineage, marked by the induction of the primordial germ cells (PGCs). The PGCs are the sole founder population of the gametes later in life, and their specification is a critical first step towards the organism's fertility. Here, a robust protocol for generating PGC-like cells (PGCLCs) from human induced pluripotent stem cells (hiPSCs) is described, starting with the initial evaluation of the pluripotent state and cellular characteristics of the hiPSCs to ensure effective PGCLC differentiation. For this, the effects of different cell densities, plate coatings, and hiPSCs used for PGCLC differentiation are discussed. Finally, a workflow for characterization and quantification of hPGCLCs, using immunofluorescence and flow cytometry, is provided. The differentiation protocol focuses on conditions that are easy to establish and test in most laboratories and can be adjusted as necessary. Moreover, this protocol is fast, allowing determination of whether hiPSCs are suitable for PGCLC differentiation. The protocol aims to promote consistency and compatibility in hPGCLC outcomes across different hiPSC lines and culture platforms, ensuring robust yields that support reliable characterization and further optimization of downstream differentiation steps toward successful in vitro gametogenesis in humans."

We generated an endogenous FOXL2-P2A-tdTomato reporter human induced pluripotent stem cell (hiPSC) line using CRISPR/Cas9 knock-in and reporter-guided transcription factor (TF) programming to produce fetal granulosa-like cells (FGLCs). A flow cytometric TF screen identified TCF21, WT1-KTS, and NR1H4 as the strongest FOXL2 inducers, and combinatorial optimization showed that removing TOX3/ETV5 and adding NR2F2 substantially increased the FOXL2-positive fraction. Bulk RNA-seq, principal component analysis, and TF activity inference positioned the induced cells close to early-gestational human fetal granulosa cell profiles. In a mouse IVM, in vitro fertilization (IVF), blastocyst culture, and embryo transfer pipeline, FGLC supplementation did not change nuclear maturation rates but improved downstream development, most clearly increasing offspring production from cumulus-oocyte complexes. A comprehensive safety assessment of F0 offspring derived from FGLC-treated oocytes revealed a normal sex ratio, postnatal growth, gross anatomy, gonadal histology, and modified SHIRPA neurobehavioral profiles. Next-generation natural mating and germ cell assays demonstrated preserved fertility, normal IVF outcomes, and normal sperm parameters in the F1 generation. These results establish a scalable strategy for generating fetal granulosa-like supporting cells from hiPSCs and provide an effective and multi-generational safety framework for oocyte-contact IVM interventions."

"abstract_text": "ID: 41593679\nTitle: Adaptation of lentiviral vectors for viral gene therapy and their impact on host cell biology.\nAbstract: Lentiviral vectors (LVVs) are used as a viral gene therapeutic and were derived from human immunodeficiency virus subtype 1 (HIV-1). LVVs are used to deliver and induce the stable expression of transgenes through genome integration. Current clinical LVV delivery systems do not include HIV-1 major accessory genes; however, critical structural and non-structural HIV-1 proteins are encoded by the 4-plasmid combination that composes the 3rd generation LVV transduction systems. LVVs use HIV-1-like mechanisms for viral genome integration and both transgene delivery and expression. LVVs rely on host cell machinery to transcribe and translate transgenes for either knocking down disease-causing genes and/or supplying functional genes in a targeted disease. LVVs integrate into host intronic and intergenic regions due to genomic accessibility, but there are no known biases toward specific target integration motifs. Investigation of LVV integration has uncovered the generation of chimeric LVV-host transcripts and altered host transcript splicing patterns. Several Food and Drug Administration (FDA)-approved LVV-derived therapies are used for treating diseases ranging from beta thalassemia to sickle cell anemia. An increasingly popular application of LVV is in the generation of chimeric antigen receptor (CAR) T cell therapies, which change and enhance T cell antigen specificity and effector function in liquid cancers. In November 2023, all CAR T cell therapies were placed under FDA investigation due to higher-than-expected rates of malignant transformation, hospitalization, and death in treated individuals. LVV integrations driving oncogene expression could be a cause for malignancy development. Current methods for resolving LVV integration patterns are technically limited by the sequencing approach applied allowing for only limited characterization of LVV integration profiles and altered host gene regulation. A comprehensive understanding of LVV integration and its consequences is necessary for understanding how these events influence host cell gene regulation and splicing, possibly identifying tunable variables for enhanced positive clinical outcomes. Here, we review the development of LVV systems, what is known about LVV integration patterns, technologies used to characterize patterns of LVV integration, and what is understood about the subsequent impact on host cell gene regulation and its potential linkage to patient malignancies."

"abstract_text": "ID: 42513228\nTitle: Breast Cancer: Epidemiology, Molecular Classification, Diagnostics and Evolving Treatment Paradigms.\nAbstract: Breast cancer remains one of the most prevalent malignancies affecting women worldwide and continues to be a leading cause of cancer-related morbidity and mortality. Patients may present with either localized or advanced disease, with clinical outcomes increasingly influenced by molecular subtype and genetic profile. This review highlights the key genetic factors involved in breast cancer, current diagnostic and therapeutic strategies, and promising emerging approaches that may shape future clinical management. Breast cancer diagnosis typically involves clinical breast examination, imaging techniques such as mammography and ultrasound, and confirmatory biopsies. Genetic mutations in specific genes are strongly linked to the development, progression, and metastasis of the disease. Treatment options for localized breast cancer continue to include surgery (lumpectomy or mastectomy) and radiotherapy, combined with systemic therapies tailored to tumor biology, such as endocrine therapy, human epidermal growth factor receptor 2 (HER2)-targeted therapy, and cyclin-dependent kinase (CDK)4/6 inhibitors. For advanced or metastatic breast cancer, recent therapeutic advances include the use of immunotherapy (e.g., immune checkpoint inhibitors), Poly (ADP-ribose) polymerase (PARP) inhibitors for Breast Cancer gene (BRCA)-mutated cancers, antibody-drug conjugates, and novel targeted agents, which have significantly improved patient outcomes in selected populations. Recent findings in breast cancer genetics have highlighted the critical role of germline and somatic mutations, particularly in genes such as BRCA1, BRCA2, phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), and TP53, in driving tumor initiation, progression, and therapeutic response. Molecular profiling and next-generation sequencing technologies have enabled more precise tumor classification and facilitated the development of personalized treatment strategies. Despite these advances, treatment resistance and disease recurrence remain major challenges, particularly in aggressive subtypes such as triple-negative breast cancer. Consequently, ongoing research is exploring alternative and complementary approaches, including nanotechnology-based drug delivery systems, gene editing techniques such as clustered regularly interspaced short palindromic repeats-Cas9 (CRISPR-associated protein 9) (CRISPR-Cas9), cancer vaccines, and the integration of traditional and plant-derived compounds. These strategies aim to enhance therapeutic efficacy, reduce systemic toxicity, and overcome resistance mechanisms."

Despite early promise, clinical adoption of IVM has been limited due to lower embryo developmental competence and live birth rates compared to IVF. However, recent advances in the understanding of oocyte physiology, including cumulus-oocyte communication, the regulatory roles of cAMP/cGMP signaling pathways, and endocrine modulation of meiotic resumption, have reignited interest in optimizing IVM protocols. Innovations such as biphasic Capacitation (CAPA) IVM systems and the use of ovarian somatic support cells (OSCs) derived from induced pluripotent stem cells (iPSCs) aim to replicate the dynamic follicular environment more accurately and enhance oocyte competence. Clinical studies suggest that, while IVM still results in modestly lower cumulative live birth rates compared to conventional IVF, it offers significant advantages for selected patient populations, particularly women with polycystic ovary syndrome (PCOS), high ovarian reserve, or those requiring fertility preservation. Importantly, current evidence supports the genetic and epigenetic safety of IVM-derived offspring. As technical refinements continue and professional education expands, IVM is poised to fulfill its potential as a safer, less invasive, and more accessible alternative within the landscape of assisted reproductive technologies."

On one side, the 14-day rule has faced criticism from embryo researchers advocating for its extension.

While advancements in scientific research, especially gene editing and in-vitro gametogenesis (IVG), are not yet fully applicable, their potential future use appears to pose significant bioethical questions. In this review, we examine the evolving bioethics of embryo research, focusing on the 14-day rule, the challenges surrounding surplus cryopreserved embryos, and the future dilemmas posed by CRISPR-based gene editing, IVG, and preimplantation genetic testing for polygenic risk (PGT-P). We also highlight the critical role of multidisciplinary, patient-centered counseling in ART practice, to foster informed consent, realistic expectations, and psychosocial well-being. Finally, we underscore the need for anticipatory ethical frameworks and open-society engagement that integrate public deliberation with scientific progress to ensure that reproductive innovation proceeds responsibly, preserving both human dignity and social justice."

"abstract_text": "ID: 42630431\nTitle: Direct neuronal reprogramming for neurological diseases: applications, translational Challenges, and future directions.\nAbstract: Neurological diseases, often caused by irreversible loss of terminally differentiated neurons, present considerable challenges to treatment due to the limited regenerative capacity of these neurons. Although induced pluripotent stem cells hold promise for neuronal regeneration, their clinical application is constrained by risks, including tumorigenicity, incomplete neuronal maturation, and immune rejection. Recent advancements in direct neuronal reprogramming, which bypasses the intermediate pluripotent stage by directly converting non-neuronal cells into functional neurons, offer a compelling alternative for in situ neuronal replacement in neurodegenerative diseases. Key transcription factors, such as NeuroD1, Ascl1, Sox2, as well as CRISPR activation (CRISPRa) of NGN2 and ISL1, have been explored to convert glial cells into neurons. However, several challenges remain. This review discusses the current applications of direct neuronal reprogramming technology in several neurological diseases. We further highlight the potential contamination issues in adeno-associated virus (AAV) delivery systems and propose a code of conduct to avoid artifacts and pitfalls. Finally, we point out future directions for expanding direct reprogramming targets, integrating organoid-based disease modeling, and advancing reprogramming regulation techniques."

This review synthesizes current advances aimed at enhancing the specificity of CRISPR diagnostics, with particular emphasis on the pivotal role of CRISPR RNA (crRNA) engineering. We detail how structural determinants of crRNA, including spacer length optimization, intentional mismatch design, secondary-structure modulation, chemical modification, strand-displacement gating, and synergistic design frameworks, govern CRISPR-mediated target recognition and define the energetic and kinetic thresholds for accurate cleavage. Key engineering strategies encompassing computational prediction and modeling, high-throughput screening, and hybrid guide architectures are systematically examined for their capacity to elevate single-nucleotide discrimination, stabilize reaction performance, and enable robust multiplexed detection for pathogen profiling and mutation identification. Despite rapid progress, outstanding challenges persist, including interference from complex clinical matrices, lack of unified evaluation standards, and scalability barriers that hinder clinical translation. Addressing these limitations through integrated crRNA design, system-level optimization, and standardized benchmarking will be essential for realizing the promise of CRISPR diagnostics. Ultimately, these advances are poised to support ultrasensitive, highly specific, and portable point-of-care testing, thereby accelerating precision medicine and strengthening infectious disease surveillance and management."

Although ssODN sequence fidelity is critical to the safety and efficacy of editing, standard quality control methods cannot resolve individual nucleotide errors. Methods: We performed deep sequencing of ssODNs from three manufacturers and amplicons from edited hematopoietic stem/progenitor cells. Results: We find that synthesis errors are present in all ssODNs tested at rates that vary more than two-fold among manufacturers, at positions that are dependent on sequence context. These synthesis errors are propagated into the genome by HDR at frequencies proportional to their abundance in the ssODN. In our sickle cell mutation correction protocol, the most prevalent SNEs are predicted to produce benign \u03b2-globin variants, while the less frequent frameshift deletions are predicted to generate \u03b2-thalassemia-like alleles. Conclusions: Current quality control standards are insufficient to detect these errors, and deep sequencing of ssODNs should be incorporated into regulatory submissions for clinical gene editing programs."

Prime editing enables precise genome modification without generating double-strand DNA breaks or requiring donor DNA templates. We established an in vitro prime editing workflow to generate and subsequently correct the mdx5cv mutation in mouse C2C12 myoblasts. Following optimization of engineered prime editing guide RNAs (epegRNAs) and PAM-flexible prime editors, wild-type cells were edited, clonally isolated, and genotyped. Mutation correction was then evaluated using optimized epegRNA designs. Two rounds of prime editing introduced the mdx5cv mutation into approximately 20% of alleles in C2C12 cells creating the mdx5cv C2C12 cell line. Clonal isolation yielded five homozygous mutant clones among 59 expanded colonies. Optimization studies identified an epegRNA containing a 16 nucleotide reverse transcription template and a 10 nucleotide primer binding site (RTT16/PBS10) as the most efficient design. Correction of the pathogenic allele reached approximately 26%, whereas longer PBS lengths reduced editing efficiency. In silico off-target analysis using Cas-OFFinder identified no candidate genomic loci with fewer than three mismatches for the spacer sequences used in either mutation generation or correction, suggesting a favorable predicted specificity profile. Corrected mdx5cv C2C12 myoblasts retained their capacity to differentiate into multinucleated myotubes. Representative Western blot analysis detected dystrophin protein expression in differentiated corrected mdx5cv myotubes, consistent with successful correction of the pathogenic mutation. These findings establish a robust prime editing platform for both the generation and correction of the mdx5cv mutation and provide proof of concept that precise correction of the pathogenic mutation is associated with restoration of dystrophin expression following myogenic differentiation."

These K27M mutations shape intratumoral myeloid cell composition in DMG. In H3.1K27M DMGs, genetic ablation of monocyte recruitment reshapes the tumor microenvironment (TME) by reducing monocyte-derived macrophages (MDMs) and increasing microglia and neutrophil presence, with overall survival remaining unchanged, indicating compensatory myeloid remodeling is occurring. Here, by using CRISPR/Cas9-based genome editing, we generated a mouse model deficient for CCR1/CCR2/CCR3/CCR5 (\u03941235). Using this strain, we effectively abolished monocyte and MDM infiltration and reversed compensatory recruitment of CCR1+ neutrophils. Abolishing MDMs in tumors skewed remaining neutrophils and microglia toward a homeostatic state, reduced expression of immune checkpoint molecules on T cells, and extended the survival of H3.1K27M DMG-bearing mice. In contrast, H3.3K27M DMG showed independence from MDM recruitment, suggesting reliance on other TME-driven signaling. Last, H3.1K27M DMGs exhibited reduced microglia presence and a dose-dependent increase in MDM infiltration postirradiation. MDM depletion did not further enhance radiation efficacy, potentially due to compensatory recruitment of classical neutrophils. Collectively, these data reveal histone mutation-specific myeloid dependencies in DMG, highlighting MDM-independent mechanisms in H3.3K27M tumors and MDM-dependent pathways in H3.1K27M tumors."

"abstract_text": "ID: 42327050\nTitle: Attenuated estrogen signaling disrupts placentation and drives trophoblast defects in Down syndrome.\nAbstract: Proper establishment of the primitive placenta and subsequent tissue homeostasis in the mature placenta are critical for successful pregnancy in humans. Placental insufficiency is associated with adverse pregnancy outcomes, including fetal growth restriction, preeclampsia, and pregnancy loss. Moreover, emerging evidence suggests that placental defects are associated with long-term health challenges that manifest well into adulthood; yet the etiologies of such diseases are largely unknown. Defining the mechanistic basis for placental deficiencies, therefore, has important implications for improving both reproductive health and the lifelong well-being of affected children. Down syndrome is characterized by placental defects of unknown mechanistic origin, and notably, individuals with Down syndrome are at increased risk of developing diseases commonly associated with placental insufficiency later in life. Using induced pluripotent stem cells from Down syndrome patients, we found that stem cell-based embryo models (i.e., blastoids) and directed differentiation systems recapitulate trophoblast cell fate defects observed in placentas affected by Down syndrome. Furthermore, we demonstrate that attenuated estrogen signaling contributes to placental syncytialization defects and identify NRIP1, a transcriptional corepressor of estrogen receptor that is located on chromosome 21, as a key driver of trophoblast cell fate defects. Increased gene dosage of NRIP1 in an otherwise diploid cell line phenocopies cell fate defects observed in trophoblasts affected by Down syndrome. Our study suggests that estrogen signaling is a crucial regulator of trophoblast development and may serve as a potential target for therapeutic intervention.

In our previous work, TNFRSF13B exon 2 variants were recurrently identified in chronic active Epstein-Barr virus disease (CAEBV). Here we aim to reveal the roles of TNFRSF13B variants in CAEBV, and investigate the feasibility of targeting TNFRSF13B/TACI as a new approach to control EBV infection. The lymphoblastoid cell lines (LCL) models carrying homozygous TNFRSF13B exon 2 frameshift mutations were constructed using CRISPR/Cas9. Immunological assays, transcriptomic analysis, and gene silencing experiments were performed on LCL models to measure the effect of TNFRSF13B exon 2 variants and explore the underlying mechanisms. TACI ligands and a TLR9 agonist were applied to modulate TACI signaling and EBV activities. Frameshift mutations in exon 2 of TNFRSF13B significantly up-regulated the short isoforms of TACI (TACI-S) at the expense of its long isoforms (TACI-L) in LCLs. The up-regulated TACI-S induced more intense activation of NF-\u03baB, MAPK, and Rho signaling pathways, leading to the switch of EBV activities to lytic reactivation. The subsequent increased viral load and viral IL-10 provide a rational for the susceptibility of variant carriers to CAEBV. The BAFF trimer, an indirect TACI-signaling inhibitor, also significantly suppressed the EBV lytic program. Gene silencing experiments indicated that XBP-1 might be involved in the TACI-mediated regulation of EBV lytic activities in EBV-immortalized B cells. This study underscores the impact of TNFRSF13B variants on EBV infection and host immune responses, offering insights into CAEBV pathogenesis and potential therapeutic strategies."

Pathogenic variants impaired proliferation, while benign variants did not. Missense variants had a more subtle effect than truncating ones, suggesting hypomorphic phenotypes. One DDX41 VUS had a significant negative effect on proliferation, suggesting it to be pathogenic, while the other two had no effect, suggesting them to be benign.

Although gap larvae exhibit normal external morphology, gap mutants exhibit severe defects in adult organs, suggesting that the gap gene is required for the development of imaginal discs and the primordia of adult organs. Genetic analysis of the gap mutation provides an opportunity to understand the molecular mechanisms underlying the development of adult organs. In this study, we performed RNA-seq analysis of ovaries from gap mutants. De novo assembly of RNA-seq reads identified the insertion of a retrotransposon in the gene encoding the Bombyx ortholog of protein-cysteine N-palmitoyltransferase (Rasp), which is required for Hedgehog signaling in Drosophila. PCR and subsequent sequencing analyses revealed that an LTR transposon is inserted into exon 1 of the BmRasp gene.

However, the path to this milestone reveals a pattern of MSCs failing in late-phase clinical trials. Multiple sources of heterogeneity may explain these results, including variability in donor and recipient biology, product manufacturing and characterization, and trial design. For example, certain subsets of acute GVHD patients, particularly those with inflammatory/immune activation, may derive the greatest clinical benefit from MSCs. Trials failing to stratify for this patient-level heterogeneity risk failure while obscuring signals of efficacy in responsive subgroups. Improving trial design considering heterogeneity requires leveraging advances in MSC manufacturing and refining clinical trial methodologies. The development of pooled and early-passage MSCs, induced pluripotent stem cell-derived (iPSC)-MSCs, biomaterial-encapsulated MSCs, and gene-edited or chimeric antigen receptor-expressing MSCs may reduce heterogeneity and improve trafficking to and survival at disease sites.

Conventional treatments, including immunotherapies and targeted inhibitors, face three main challenges: tumor heterogeneity, drug resistance, and systemic toxicity. Nucleic acid therapeutics (NATs) encompass a diverse array of DNA- and RNA-based tools, including small interfering RNA (siRNA), microRNA (miRNA), messenger RNA (mRNA), antisense oligonucleotides (ASOs), and clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) systems. These tools are central to developing precision oncology approaches that operate through direct gene regulation, mutation correction, and immune system reprogramming. The clinical application of NATs currently faces three main obstacles, which include their vulnerability to enzymatic degradation, their limited ability to penetrate tissues, and their tendency to cause off-target effects. The field has progressed through the implementation of nanoformulation techniques, which utilize lipid-based polymeric and metallic carriers together with exosomes and DNA origami, and hybrid nanostructures as new platforms to enhance the stability of drugs and their cellular absorption and targeted delivery to tumors. The scientists developed functionalized nanocarriers by combining targeting ligands with materials that could respond to specific environmental changes, which allowed them to manage drug distribution and release patterns throughout the tumor microenvironment. This review focuses on establishing a direct connection between nucleic acid design and nanotechnology through an analysis of mechanistic details and progress in preclinical and clinical research, and the difficulties encountered during the progress to practical applications. The research demonstrates how artificial intelligence and bioinspired nanocarriers and multi-omics data integration create new opportunities for developing personalized adaptive nanogenetic treatment methods, which will treat lung cancer.

In disease modelling, iPSC-derived liver organoids faithfully recapitulate the pathological progression of metabolic dysfunction-associated steatotic liver disease (MASLD) and verify the lipid-lowering efficacy of semaglutide. Macrophage-integrated organoid models support the full life cycles of HEV, SARS-CoV-2 and dengue virus, providing new tools for antiviral drug screening. Large-scale patient-derived tumour organoid biobanks successfully preserve the heterogeneity and clinical drug-resistance signatures of liver cancers. In regenerative medicine, encapsulated hepatocyte organoids and the UTOpiA bioartificial liver system have effectively rescued acute liver failure in animal models, while gene-edited autologous organoids offer potential curative strategies for genetic disorders such as Wilson disease. Nevertheless, insufficient hepatocyte functional maturity, difficulties in constructing vascular networks, and the lack of standardised culture protocols remain major obstacles to clinical translation. By bridging fundamental liver biology and clinical practice, liver organoid technology lays a solid foundation for precision hepatology and regenerative therapies. Continued interdisciplinary efforts are still required to overcome current limitations and facilitate its clinical adoption."

Reliable generation of defined neuronal populations, such as gamma-aminobutyric acid (GABAergic) neurons, is essential for these studies. This protocol details a robust method for differentiating hiPSCs into GABAergic neurons using a doxycycline-inducible system. The approach relies on the stable integration of transgenes encoding the transcription factors ASCL1 and DLX2 into the safe-harbor adeno-associated virus integration site 1 (AAVS1.) locus via CRISPR/Cas9-mediated knock-in. This targeted integration avoids the transgene silencing often observed with random lentiviral integration. The protocol covers the maintenance of hiPSCs, the nucleofection process for transgene integration, puromycin selection to enrich successfully engineered cells, and the step-by-step differentiation procedure. Upon induction with doxycycline, the engineered hiPSCs rapidly exit the cell cycle, acquire neuronal morphology, and express GABAergic lineage markers within 21 days. Key steps include neuro-induction and subsequent maturation using specific growth factors, as well as potential approaches to improve cellular adhesion during maturation. This standardized method yields enriched populations of induced neurons expressing GABAergic lineage markers, providing a valuable tool for neuroscience research and cellular modeling."

Here, we establish the first comprehensive human mechanistic model of PPP1R9A haploinsufficiency using an isogenic CRISPR/Cas9-engineered iPSC system differentiated into cortical neurons to define dosage-dependent functional consequences. PPP1R9A+/- neurons exhibited pronounced hyperspinogenesis and increased neuritic complexity, indicative of aberrant structural maturation; however, whole-cell patch-clamp recordings revealed impaired intrinsic excitability, including reduced action potential firing, altered waveform properties, and defective axo-somatic coupling, uncovering a striking dissociation between neuronal morphology and function. Long-read single-cell transcriptomics and quantitative proteomics identified coordinated downregulation of ion channel and synaptic transmission pathways, including genes essential for sodium channel function and glutamatergic signaling, together with disruption of synaptic vesicle cycling, axon guidance, and neurodevelopmental programs. Pseudotime trajectory analysis further demonstrated delayed neuronal differentiation, with mutant neurons accumulating at intermediate developmental states rather than acquiring mature cortical identities. Importantly, molecular rescue experiments confirmed causality, as restoration of full-length PPP1R9A expression robustly normalized transcriptional and synaptic signaling programs, whereas allele-specific antisense oligonucleotide-mediated suppression of the mutant transcript achieved only partial rescue. Taken together, these findings establish PPP1R9A haploinsufficiency as a driver of impaired molecular, electrophysiological, and developmental maturation in human cortical neurons, providing a human-specific mechanistic framework linking reduced Neurabin I dosage to neurodevelopmental and psychiatric disease risk."

Although stem cell-based therapies have shown promise for vascular regeneration, their clinical translation has been limited by poor survival, insufficient engraftment, functional heterogeneity, and immune rejection. Recent advances in genome-editing technologies, including CRISPR/Cas9, base editing, and prime editing, have provided powerful tools for overcoming these limitations through precise genetic modification of stem cells. Gene editing can enhance angiogenic potential, improve resistance to ischemic stress, augment paracrine activity, promote endothelial maturation, and reduce immunogenicity. In this review, we outline the current genome-editing toolbox and its application to stem cell engineering for vascular regeneration in ischemic disease. We also examine emerging therapeutic concepts, universal donor cell platforms, and key issues in safety and ethics, with a focus on translational pathways. Taken together, advances at the interface of genome editing and stem cell biology are likely to accelerate the development of regenerative therapies that deliver more durable vascular repair in ischemic vascular disease."

In this study, the BCH gene in Nicotiana tabacum was targeted using CRISPR/Cas9 genome editing to redirect metabolic flux toward \u03b2-carotene accumulation and evaluate its effects on heat tolerance. Following Agrobacterium-mediated transformation with a BCH-specific gRNA, three mutant plants were obtained; two carrying frameshift mutations (P1 and P3) and one with mis-sense mutations (P2). A significant increase in chlorophyll contents was observed in the edited lines compared with wild-type plants. Interestingly, the frameshift mutants exhibited substantial increase in total chlorophyll (71% and 31% in P3 and P1 respectively) as compared to mis-sense mutant P2 (18%). Further, biochemical profiling using HPLC showed that the edited plants accumulated 3.74-fold increase in \u03b2-carotene than wild-type plants. Under heat stress (42\u202f\u00b0C for 96\u202fh), the edited plants exhibited enhanced thermotolerance by remaining greener and delayed wilting, whereas wild-type plants developed necrosis rapidly under heat stress. This enhanced thermotolerance might has resulted from the increased expression of \u03b5-cyclase (an upstream key enzyme in \u03b2-carotene biosynthesis) as revealed by expression profiling of edited plants. In contrast, the expression of downstream \u03b2-cryptoxanthin and zeaxanthin biosynthetic genes was reduced, which seems consistent with mutation of BCH. DAB staining further confirmed reduced ROS accumulation in edited plants as compare to wild type supporting the protective role of \u03b2-carotene. In summary, the downregulation of BCH in N. tabacum boosted \u03b2-carotene levels and chlorophyll retention, enhancing heat stress tolerance. These findings demonstrate the potential of targeting carotenoid biosynthesis to improve crop resilience."

We integrated single-cell RNA sequencing, epithelial CNV-like inference, fibroblast reclustering, CellChat analysis, signature scoring, hdWGCNA, CAF-epithelial coupling, exploratory GSE14209 evaluation, TCGA-STAD mutation/copy-number contextualization, and DepMap CRISPR virtual knockout analysis, followed by experimental validation in AGS and HGC-27 cells. IGF1+ CXCL12+ CAFs showed resistance-supportive stromal features, and CAF-epithelial coupling prioritized ARPC1A as a tumor epithelial candidate associated with this stromal program. In TCGA-STAD, ARPC1A mutations were rare and consisted of three missense and two frameshift variants without a recurrent hotspot; the mutant tumors were confined to the MSI subtype and showed an immune-activated, high TMB/MSI context, indicating mutation-immune crosstalk rather than a clear mutation-specific CAF, EMT, drug resistance, or cisplatin response phenotype. By contrast, ARPC1A copy-number gain/amplification was more frequent and tracked with ARPC1A expression, CIN enrichment, aneuploidy, and fraction of genome altered. DepMap CRISPR data indicated mostly weak-to-mild baseline ARPC1A dependency in upper GI and gastric/GEJ models. Experimentally, ARPC1A knockdown increased cisplatin sensitivity, promoted cisplatin-induced apoptosis, and suppressed migration and invasion. These findings identify a CAF-associated ARPC1A epithelial program linked to cisplatin response and support a mutation-immune/copy-number framework in which ARPC1A is interpreted mainly through immune-contextual mutation patterns and expression dosage rather than recurrent gain-of-function mutation."

It may act in a very disparate manner; ranging between slow growing, well differentiated tumours to an aggressive anaplastic subtype. Initial treatment with standard therapy, surgery, radioactive iodine, the thyroid-stimulating hormone inhibition and in some cases, chemotherapy or external-beam radiations are effective with the differentiated cancers at the early stages. Nevertheless, there is no choice with tumours, which become unresponsive to iodine, metastasized, or un- differentiated. Recent developments in molecular oncology have elucidated the genetic alterations that contribute to thyroid cancer, in particular, the MAPK and PI3K/AKT/mTOR pathways, and BRAF, RAS, RET, and TERT promoter mutations. The current review summarizes the changing therapeutic environment of thyroid cancer that includes established targeted medicines and novel developments. These are immune checkpoint inhibitors, redifferentiation based on reinstatement of iodine uptake, selective RET and BRAF/MEK, RNA-based therapeutics, CRISPR gene editing, oncolytic virotherapy, peptide receptor radionuclide therapy, alpha-particle radiotherapy, and nanotechnology-based drug delivery systems. A combination regimen involving molecular targeting and immunotherapy or radioactive iodine is also improving the disease in advanced disease. Collectively, the advances are an indication of a transition to the personalized, mechanism-driven treatment strategies that would prolong the survivability of patients with advanced thyroid cancer, conquer resistance, and reduce systemic toxicity."

A novel body shape mutant, stony^sunken (st^sk), that exhibits a sunken intersegmental membrane was isolated from the wild type of st^sk (WT-n08). Investigation indicated that the mutation had no significant effect on its growth and development. To elucidate the molecular mechanism underlying this body shape mutant, genetic analysis, positional cloning, and the CRISPR/Cas9 gene editing system were performed. Genetic analysis demonstrated that the mutant trait in st^sk is controlled by an autosomal recessive gene and follows Mendelian inheritance. Positional cloning showed that a putative cuticular protein gene, BmorCPR2 on chromosome 8, was the candidate gene. Sequencing analysis revealed partial deletion of BmorCPR2 exon 2 and intron 2 sequences occurred and subsequently resulted in the premature termination of gene expression. Knock-out of BmorCPR2 using the CRISPR/Cas9 gene editing system led to the sunken intersegmental membrane phenotype. These findings highlight the essential role of BmorCPR2 in silkworm cuticular formation, providing a foundation for further research on cuticular protein function."

Here we study APP specifically in the context of Trisomy 21. In an effort to reduce APP dosage in trisomy 21 iPSCs, we generated trisomic isogenic lines which vary in APP dosage, including a full APP knock-out line, as well as lines carrying mutations of the APP extracellular domain. We used a panel of these lines to study potential impacts of APP dosage or structure on two distinct steps of neurogenesis in trisomic cells: 1) terminal differentiation of human neuro-progenitor cells (NPC) to post-mitotic neurons and 2) neuron structure as reflected in neurite outgrowth. Complete loss of APP causes marked defects in each of these two distinct steps, reducing both the terminal differentiation of NPCs to neurons, and proper neurite development for extended neuron structure. Hence, APP is necessary for both aspects of normal neurogenesis. Further analyses of the null and other mutant lines indicate that APP likely impacts these two distinct steps by two different mechanisms. Collective results suggest that the reduced terminal differentiation of NPCs reflects an effect of APP dosage, whereas the defects in neurite extension are due to structural mutation of the APP extracellular domain. Absence of APP or reduced (monosomic) APP dosage prolonged the cycling of trisomic NPCs, which is known to be regulated by Notch signaling. APP and Notch are the main targets of gamma-secretase cleavage, hence we hypothesized that APP dosage may impact neurogenesis indirectly, potentially via effects on Notch signaling. To test this, we treated NPCs with Compound E which inhibits gamma-secretase (and Notch signaling); results show this restored levels of neurogenesis in APP depleted lines, supporting an indirect effect of APP dosage . In contrast, results indicate that disruption of APP extracellular domain integrity impacts neurite extension via a more direct role of APP in neuron structural maturation. This study describes a resource of well-characterized APP mutant isogenic DS iPSC lines, implicates a dynamic interplay between APP dosage and Notch signaling, and raises new questions about the impact of APP dosage in orchestrating neural progenitor fate decisions during human brain development, specifically in the context of trisomy 21."

However, traditional microinjection methods for RNP delivery in insect embryos are labor-intensive, technically demanding, and often reduce embryo viability, especially in species with fragile, microscopic embryos. In this study, a novel, non-invasive delivery method for the RNP complex in tiny insect embryos has been optimized. Whitefly, Bemisia tabaci, an invasive insect pest of agricultural importance and vector of plant diseases, was considered as a model organism. A needleless dechorionation-permeabilization method was employed to deliver the RNP complex to the early embryonic stage of B. tabaci embryos. B. tabaci heat shock protein 70 (hsp70) gene, which interacts with the begomovirus coat protein, aiding in its internalization and successful transmission by B. tabaci in a persistent circulative manner, was targeted for knockout. Two sgRNAs were synthesized via in vitro transcription, and the Cas9-sgRNA complexes were validated by in vitro cleavage assays. The localization of the GFP-labelled Cas9-sgRNA complex confirmed successful RNP delivery, as observed through confocal microscopy. A survival rate of 18% of the embryos was recorded post-RNP delivery. Sequencing of treated embryos showed 25- and 28-nucleotide deletions in the hsp70 exon. Synthego ICE analysis revealed up to 84% gene knockout efficiency. This method enables batch processing of embryos, drastically reducing delivery time and associated costs while improving throughput. Hsp70 KO B. tabaci mutants generated in the study are expected to be incompetent begomovirus transmitters, which would help restrict the spread of the virus. Our study overcomes a key bottleneck in CRISPR/Cas delivery to small insect embryos, opening new avenues for rapid, high-throughput, and cost-effective RNP delivery methods in insect embryos. The novel non-invasive methods would be helpful in the deployment of gene editing for sustainable pest control."

Here, we quantitatively examine the energetic and catalytic consequences of PAM-interacting mutations in three engineered variants, en1 (E1369R), en15 (E1603H), and en31 (G1243T/E1369R/E1449H), using a VEGFA3 DNA substrate framework. Microscale thermophoresis and isothermal titration calorimetry reveal that the engineered variants enhance binding affinity toward the canonical NGG PAM relative to wild-type FnCas9, with modest gains in binding free energy. Selected noncanonical PAM substrates, particularly TGA and TAG, also show improved binding by en15 and en31, with en31 displaying the strongest overall binding among the substrates tested. Thermodynamic profiles indicate that enhanced affinity is associated with more favorable enthalpic contributions, consistent with altered interactions at the PAM interface; however, the specific molecular contributions underlying these changes remain to be directly established. Despite improved binding, active-site titration reveals reduced fractions of catalytically competent enzyme in engineered variants, particularly en31, necessitating higher enzyme concentrations to achieve cleavage efficiencies comparable to wild-type. Cleavage assays demonstrate that en31 most effectively couples improved recognition of the tested noncanonical PAM substrates to productive catalysis, enabling robust cleavage of both TGA and TAG substrates while maintaining minimal off-target activity under the conditions examined. Together, these results suggest that PAM-interacting mutations in FnCas9 can alter the energetic coupling between DNA binding and catalytic activation within the VEGFA3 substrate framework tested, highlighting the importance of balancing substrate affinity with conformational activation in the design of high-precision genome-editing nucleases."

MicroRNAs (miRNAs) have emerged as an essential post-transcriptional regulator of host-virus interactions, influencing viral replication, immunological responses and disease progression. This review offers a comprehensive overview of the miRNA-virus axis in RNA virus infections, highlighting the dynamic and context-dependent roles of host miRNAs. We investigate the mechanistic basis of miRNA-mediated regulation, including direct targeting of viral RNA, modulation of host dependency factors, regulation of antiviral signaling pathways, and immune-mediated effects on infection outcomes. We propose a functional categorization of miRNAs that transcends the conventional antiviral-proviral dichotomy, facilitating a more accurate comprehension of their involvement in various infection settings. This review connects mechanistic insights with translational applications by outlining novel treatment techniques, such as miRNA mimics, anti-miRs, RNA interference, and CRISPR-based methodologies. We also propose a therapeutic decision framework that links miRNA functional classification with targeted antiviral interventions. Key challenges including delivery efficiency, tissue specificity, and off-target effects are also discussed, with emphasis on lipid nanoparticles and exosome-based delivery systems.

In this study, we established a highly sensitive and specific assay by combining peptide nucleic acid (PNA)-mediated PCR clamping with CRISPR/Cas13a trans-cleavage detection. A PNA probe targeting the wild-type (WT) EGFR T790M allele was designed to suppress WT amplification during PCR, while minimally affecting mutant allele amplification. By combining the target specificity of Cas13a for mutant alleles with the WT-suppression capability of PNA-PCR, we achieved a dual-enrichment effect for mutant detection. When applied to EGFR T790M mutation detection, the assay reached an analytical sensitivity of 0.02%. We established a standard curve for T790M detection using cell-free DNA standards. Clinical validation in 20 plasma samples from lung adenocarcinoma patients demonstrated that the PNA-Cas13a assay achieved a diagnostic sensitivity of 93.3% (95% CI: 68.1%-99.8%) and a specificity of 100% (95% CI: 47.8%-100%), with detection concordance comparable to or improved over ARMS-PCR in this pilot cohort. The results suggest its preliminary diagnostic utility in liquid biopsy.

We previously identified RNA viruses that infect the nematodes C. elegans and C. briggsae in a species-specific manner. Wild strains of both host species demonstrate ample variation in viral sensitivity. Here we use recombinant inbred lines and pool-sequencing approaches to genetically map a major resistance locus in the C. elegans MY10 strain, narrowing down its position by CRISPR/Cas9 mediated recombination and testing candidates by genome editing. A rare non-synonymous polymorphism in the gtnt-1 gene, encoding a putative glycosyltransferase of the GT92 family, causes resistance to viral infection in MY10. Loss-of-function gtnt-1 alleles conferred host protection only at late developmental stages, highlighting the importance of multigenerational assays capturing the full course of viral infection and transmission. Viral resistance through gtnt-1 mutation occurred repeatedly in C. elegans, with diverse alleles each remaining at low frequency (<1%). Furthermore, leveraging closely related C. briggsae strains differing in viral susceptibility, we find that repeated loss-of-function alleles of the Cbr-gtnt-1 ortholog similarly enhanced resistance and host fitness upon infection. In conclusion, recurrent evolution in two host species of loss-of-function alleles of gtnt-1 orthologs leads to viral resistance. The gtnt-1 gene being conserved between Caenorhabditis species, these repeated inactivation events provide a case of transient ecological adaptation to a pathogen through recurrent mutation of the same gene in two species. The low population frequencies of resistant alleles point to a changing eco-evolutionary context that prevents their spread in populations."

Here, we integrate ex vivo drug sensitivity profiling, genomics, transcriptomics, and proteomics across 167 CD138+ bone marrow patient samples to characterize TP53-associated vulnerabilities. Genome-wide CRISPR-Cas9 and RNAi screening identify vulnerabilities in TP53-mutated MM, with or without del(17p), highlighting the dependency on spindle organization, mitotic regulation, DNA synthesis, and transcriptional and metabolic regulation, but independence from MDM2. CD138+ cells with TP53 mutation exhibit increased sensitivity to chemotherapeutics, HDAC, HSP90, IGF1R, and PI3K/AKT/mTOR inhibitors as well as RNA synthesis inhibitor plicamycin, with distinct drug response profiles of MM with del(17p) and WT TP53. Our study provides new insights into refining TP53 classification to optimize treatment strategies for high-risk MM."

Its continued success relies on further refinement of gene transfer technologies, gene editing tools such as CRISPR-Cas, and optimized ex vivo HSPC manipulation protocols that ensure robust, long-term engraftment and clonal diversity with reduced-toxicity, non-genotoxic conditioning strategies. Here, we review recent developments and refinements in gene transfer and editing technologies for HSPCs, while also discussing the critical limitations and hurdles to clinical translation, as recently presented at the New Investigator Committee Gene Therapy webinar. Future directions must prioritize integrating technological innovation with the development of equitable and simplified models to reduce costs and ensure that these life-saving cellular therapies reach patients worldwide. Teaser abstract Hematopoietic stem and progenitor cells (HSPCs) gene therapy is advancing rapidly, with lentiviral gene transfer, genome editing, and emerging in vivo delivery approaches expanding the therapeutic landscape for inherited hematologic disorders.

Rhesus induced pluripotent stem cells (RhiPSCs) derived from these monkeys present a unique opportunity for in vitro modeling and comparison with cells derived from MAPT R406W human carriers. Here, we report the development of a reproducible method to generate RhiPSCs compliant with the standards of the International Society for Stem Cell Research (ISSCR) to support in vitro modeling of FTD-MAPT R406W. Our stepwise approach identified efficient methods for fibroblast derivation, fibroblast reprogramming to RhiPSC, and RhiPSC maintenance over continued culture. To derive fibroblasts from MAPT wild type (WT) and R406W monkeys, a combination of manual processing and overnight enzymatic digestion was required to maximize the number of low passage fibroblasts available for reprogramming. Fibroblast reprogramming to RhiPSC using Sendai viral vectors versus oriP/EBNA1 episomal plasmids revealed the latter as most efficient. Electroporation conditions for oriP/EBNA1 reprogramming were optimized to maximize plasmid uptake and cell survival. Ultimately, eight RhiPSC lines were derived from 4 donor rhesus monkeys (n = 2 WT, n = 2 R406W; two clonal lines per donor) and fully characterized according to ISSCR standards. RhiPSC stemness and genetic stability was best maintained on mouse embryonic fibroblast feeders in Universal Primate Pluripotency Stem Cell medium, as opposed to Essential 12 medium supplemented with IWR1, which produced cytogenetic abnormalities. Rhesus neural progenitor cells were generated using a monolayer protocol and expressed PAX6 and NESTIN after 21 days of differentiation. Our reliable method will be useful to labs seeking to derive RhiPSCs for preclinical studies. Overall, the RhiPSCs generated from MAPT R406W carriers will be a critical resource for evaluating the molecular underpinnings of tau-related neurodegeneration across primate species."

"abstract_text": "ID: 42589549\nTitle: Molecular Mechanisms Underlying Antimicrobial Resistance in Mycobacteria.\nAbstract: Antimicrobial resistance in mycobacteria arises from a complex interplay of intrinsic and acquired mechanisms that collectively limit the efficacy of current therapeutic options. Intrinsic resistance is largely driven by the low permeability of the mycobacterial cell envelope, the activity of efflux pumps, and the presence of drug-modifying enzymes, which together restrict intracellular drug accumulation and contribute to broad baseline tolerance. This review integrates resistance mechanisms of both M. tuberculosis and M. abscessus, two clinically relevant mycobacteria that share core molecular pathways while exhibiting species-specific determinants that complicate treatment. Additional intrinsic factors, including biofilm formation and stress-induced adaptive responses, further enhance persistence and reduce susceptibility to multiple drug classes. Acquired resistance predominantly results from chromosomal mutations affecting drug targets or prodrug activation pathways, such as katG, inhA, rpoB, gyrA, and pncA in Mycobacterium tuberculosis, leading to high rates of multidrug-resistant and extensively drug-resistant disease. In nontuberculous mycobacteria, species-specific determinants-including inducible macrolide resistance mediated by erm(41) in M. abscessus, plasmid-mediated erm (55) variants, rrl and rrs mutations, diverse enzymatic inactivation systems, and regulatory alterations in the MarR family that result in inducible resistance to drugs such as ethionamide -generate highly variable resistance profiles that complicate treatment. Recent advances in molecular diagnostics, including PCR-based assays, whole-genome sequencing, CRISPR-based diagnostic platforms, AI-assisted diagnostics, and emerging multi-omics approaches, have improved the detection of resistance-associated mutations and enhanced understanding of mycobacterial pathophysiology. In parallel, new therapeutic agents and optimized regimens offer promising avenues to overcome resistance, although emerging resistance to novel drugs underscores the need for continued surveillance. This review synthesizes current knowledge on the molecular basis of resistance in M. tuberculosis and NTM, highlighting implications for diagnosis, treatment, and future research."

These conditions are characterized by impaired cholesterol synthesis together with the accumulation of disease-specific sterol intermediates. Current experimental and clinical evidence suggests that pathogenesis reflects both cholesterol insufficiency and sterol-mediated toxicity, including oxidative stress, perturbed developmental signaling, membrane dysfunction, and impaired neurodevelopment. Experimental models have played a central role in elucidating these mechanisms and in evaluating emerging therapeutic strategies. This review provides a comprehensive overview of currently available experimental models used to investigate inherited cholesterol biosynthesis disorders, including genetically engineered animal models, patient-derived fibroblasts, immortalized and CRISPR/Cas9-edited cell lines, and induced pluripotent stem cell-based systems. Particular emphasis is placed on Smith-Lemli-Opitz syndrome, the most extensively studied disorder within this group, while recent advances in modeling desmosterolosis, lathosterolosis, and congenital hemidysplasia with ichthyosiform nevus and limb defects syndrome are also critically discussed. We compare the strengths and limitations of each experimental platform, highlighting their contributions to understanding sterol metabolism, developmental abnormalities, and cell-type-specific disease mechanisms. Finally, we discuss current challenges and future perspectives, including the development of patient-specific induced pluripotent stem cell models, genome editing approaches, and next-generation multicellular systems. Collectively, this review provides an updated framework for selecting appropriate experimental models to investigate cholesterol biosynthesis disorders and accelerate the development of mechanism-based therapeutic strategies."

No approved therapy restores myocardium lost to infarction. The adult heart replaces cardiomyocytes at approximately 1% per year in young adults, declining to about 0.45% per year with ageing, far below what is needed to recover the more than one billion cells destroyed by a large myocardial infarction. Cell-based regenerative strategies have been investigated for more than two decades, encompassing bone marrow mononuclear cells (BM-MNCs), mesenchymal stromal cells (MSCs), cardiac progenitor cells, cardiosphere-derived cells (CDCs), skeletal myoblasts, and induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs). Safety has been consistent. Efficacy has been modest and variable: the CADUCEUS trial demonstrated scar mass reduction with CDCs without proportionate ejection fraction improvement; the Phase 1/2 POSEIDON trial confirmed MSC safety in 30 patients; and the Phase 3 DREAM-HF trial, enrolling 537 patients, failed its primary endpoint (HR 1.2, p = 0.406). Mechanistic work has established that transplanted cells engraft poorly and exert their benefit principally through paracrine signalling mediated by secreted extracellular vesicles and exosomes carrying microRNAs, trophic factors, and immunomodulatory proteins. For iPSC-CMs, electrophysiological immaturity and arrhythmogenic risk in primate models remain unresolved barriers. Emerging strategies include CRISPR-engineered hypoimmune iPSC lines, bioengineered cardiac patches, injectable hydrogel scaffolds, and engineered exosome platforms. This review provides a comprehensive synthesis of preclinical and clinical evidence, examines translational barriers, and identifies the scientific and regulatory priorities required before these therapies can enter routine clinical practice."

This review summarizes the clinical development of novel treatments for both non-transfusion-dependent and transfusion-dependent \u03b2-thalassemia, including approved therapies, agents in active development, and programs that have been discontinued. Disease-modifying strategies have focused on improving ineffective erythropoiesis, correcting iron dysregulation, and restoring red blood cell metabolism.

Approved therapies, including betibeglogene autotemcel and exagamglogene autotemcel, have achieved high rates of durable transfusion independence, while emerging platforms aim to further improve efficacy, safety, and accessibility. At the same time, several promising approaches targeting fetal hemoglobin induction, iron metabolism, and ineffective erythropoiesis have failed to demonstrate sufficient clinical benefit despite preclinical proof of concept, highlighting the complexity of therapeutic development in \u03b2-thalassemia.

Conventional treatments, such as blood transfusions, iron chelation, fetal haemoglobin induction, and allogeneic haematopoietic stem cell transplantation, have improved outcomes but remain limited by treatment-related toxicity, donor availability, and incomplete curative potential. Methods: A narrative literature review was conducted using PubMed up to 2025. Search terms included \"sickle cell disease,\" \"sickle cell anemia,\" \"\u03b2-thalassemia,\" \"transfusion-dependent beta-thalassemia,\" \"gene therapy,\" \"gene addition,\" \"gene editing,\" \"CRISPR-Cas9,\" \"lentiviral vector,\" \"children,\" \"paediatric,\" and \"pediatric.\" Relevant clinical trials, reviews, consensus statements, and guidelines were selected and qualitatively analysed. Results: Gene therapy for \u03b2-haemoglobinopathies is based mainly on two strategies: gene addition and gene editing. Gene addition uses lentiviral vectors to introduce functional or modified \u03b2-globin genes into autologous haematopoietic stem cells, whereas gene editing targets regulatory pathways, particularly BCL11A, to reactivate fetal haemoglobin synthesis or correct disease-causing mutations. Clinical studies have shown encouraging outcomes, including transfusion independence in many patients with \u03b2-thalassaemia and marked reduction or elimination of vaso-occlusive crises in sickle cell disease. Paediatric and adolescent data are increasingly promising, although still limited. Conclusions: Gene therapy is reshaping the treatment landscape of \u03b2-haemoglobinopathies by offering a personalised and potentially curative approach. However, long-term safety, conditioning toxicity, fertility preservation, accessibility, costs, and implementation in high-prevalence regions remain critical challenges. Further studies are needed to optimise patient selection and expand equitable access."

For many decades now, the emergence of synthetic biology as an intervention to correct diseases has become the foundation of biomedical research. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based genetic editing has become a common place for routine investigation of scientific hypotheses in pre-clinical settings. More recently, CRISPR-based diagnostic testing kits for SARS-CoV-2 have showcased a translational output. Furthermore, a technological landmark was achieved when the Food and Drug Administration (FDA) approved the first CRISPR-based gene therapy (exa-cel) to edit erythroid specific enhancer region of BCL11A in hematopoietic stem cells, introduced in patients suffering from sickle cell anemia to achieve durable remission.

Ex vivo CRISPR-Cas9 editing of autologous CD34-positive hematopoietic stem and progenitor cells to reactivate fetal hemoglobin has produced durable freedom from severe vaso-occlusive crises in SCD and sustained transfusion independence in TDT. This approach offers a donor-independent alternative to allogeneic hematopoietic stem-cell transplantation without graft rejection or graft-versus-host disease. Hemoglobinopathies, therefore, provide the first clinically validated delivery model for CRISPR therapeutics. Successful implementation, however, requires more than editing efficacy. It depends on structured referral, candidacy assessment, organ function review, mobilization and collection, centralized manufacturing, pharmacokinetic-guided myeloablative conditioning, transplant-level supportive care, fertility preservation, psychosocial support, and prolonged surveillance coordinated among primary hematologists and cellular therapy programs. Key barriers include stem cell collection, conditioning-related toxicity, cost, reimbursement friction, and persistent inequities in access. Long-term follow-up and registry participation are necessary to evaluate outcomes beyond pain crises, identify late toxic effects, and compare real-world effectiveness across gene editing, gene addition, and allogeneic transplantation. In oncology, CRISPR-based therapy remains investigational, with early clinical feasibility demonstrated in relapsed or refractory B-cell malignancies, T-cell malignancies, AML, multiple myeloma, and selected solid tumors.

Early efforts to derive human germ cells from stem cells were hindered by low efficiency, subpar characterization, and the lack of standardized differentiation approaches. However, recent advancements have led to the development of defined protocols that mimic early embryonic development and allow the specification of transcriptomically and epigenetically validated human primordial germ cell-like cells (hPGCLCs). Current research focuses on maturing hPGCLCs in vitro, particularly within 3D culture systems that resemble their physiological microenvironment, with the aim of producing transplantable hiPSC-derived spermatogonial stem cells (SSCs) or differentiating them to sperm. At the same time, researchers are also testing whether hiPSCs generated from infertile patients can resume germline differentiation. This narrative review aimed to summarize the key efforts and remaining challenges in differentiating male germ cells from human pluripotent stem cells (hPSCs), with a particular focus on defined and validated protocols for hPGCLC specification. In parallel, we addressed key safety and ethical considerations that must be accounted for the development of clinical applications. A deeper understanding of the approaching therapeutic use of hiPSCs in reproductive medicine is essential for developing novel regenerative fertility strategies. PubMed, Scopus, and Web of Science were searched for studies attempting germ cell differentiation from hPSCs using relevant keywords ('stem cells', 'human pluripotent stem cells', 'human embryonic stem cells', 'human induced pluripotent stem cells', 'somatic cell reprogramming', 'infertility', 'germline', 'spermatogenesis', 'germ cells', and 'primordial germ cells'). No time period restriction was established. Studies with an exclusive focus on female germline differentiation were excluded. To maintain a human-focused perspective, only key animal studies are presented. The literature reveals a clear segregation among protocols for deriving germ cells from hPSCs, particularly between earlier studies lacking standardized differentiation conditions and characterization, and the most recent, defined protocols having transcriptomic and epigenetic validation against in vivo hPGCs. Moreover, during the last decade, the field has seen remarkable progress, with multiple efforts aimed at maturing hPGCLCs, closely recapitulating late male embryonic germline development. Additionally, hiPSCs derived from male patients at risk of infertility, particularly those without underlying genetic syndromes, generally retain the capacity for early germline commitment. While attempts at maturating patient germ cells beyond the hPGCLC state remain limited, the rapid pace of discovery and refinement in recent years suggests that further breakthroughs, including clinically applicable fertility restoration strategies, are likely to be achieved in the near future. The ability to generate hiPSCs from infertile patients and to specify them into hPGCLCs supports the feasibility of obtaining hiPSC-derived SSCs for future therapeutic use. These advances raise important ethical, regulatory, and societal questions that must be actively discussed among researchers, clinicians, policymakers, and the general public to ensure responsible and equitable access to these technologies.

One of the first embryonic lineages to be specified in the human embryo is the germ cell lineage, marked by the induction of the primordial germ cells (PGCs). The PGCs are the sole founder population of the gametes later in life, and their specification is a critical first step towards the organism's fertility. Here, a robust protocol for generating PGC-like cells (PGCLCs) from human induced pluripotent stem cells (hiPSCs) is described, starting with the initial evaluation of the pluripotent state and cellular characteristics of the hiPSCs to ensure effective PGCLC differentiation. For this, the effects of different cell densities, plate coatings, and hiPSCs used for PGCLC differentiation are discussed. Finally, a workflow for characterization and quantification of hPGCLCs, using immunofluorescence and flow cytometry, is provided. The differentiation protocol focuses on conditions that are easy to establish and test in most laboratories and can be adjusted as necessary. Moreover, this protocol is fast, allowing determination of whether hiPSCs are suitable for PGCLC differentiation. The protocol aims to promote consistency and compatibility in hPGCLC outcomes across different hiPSC lines and culture platforms, ensuring robust yields that support reliable characterization and further optimization of downstream differentiation steps toward successful in vitro gametogenesis in humans."

We generated an endogenous FOXL2-P2A-tdTomato reporter human induced pluripotent stem cell (hiPSC) line using CRISPR/Cas9 knock-in and reporter-guided transcription factor (TF) programming to produce fetal granulosa-like cells (FGLCs). A flow cytometric TF screen identified TCF21, WT1-KTS, and NR1H4 as the strongest FOXL2 inducers, and combinatorial optimization showed that removing TOX3/ETV5 and adding NR2F2 substantially increased the FOXL2-positive fraction. Bulk RNA-seq, principal component analysis, and TF activity inference positioned the induced cells close to early-gestational human fetal granulosa cell profiles. In a mouse IVM, in vitro fertilization (IVF), blastocyst culture, and embryo transfer pipeline, FGLC supplementation did not change nuclear maturation rates but improved downstream development, most clearly increasing offspring production from cumulus-oocyte complexes. A comprehensive safety assessment of F0 offspring derived from FGLC-treated oocytes revealed a normal sex ratio, postnatal growth, gross anatomy, gonadal histology, and modified SHIRPA neurobehavioral profiles. Next-generation natural mating and germ cell assays demonstrated preserved fertility, normal IVF outcomes, and normal sperm parameters in the F1 generation.

LVVs are used to deliver and induce the stable expression of transgenes through genome integration. Current clinical LVV delivery systems do not include HIV-1 major accessory genes; however, critical structural and non-structural HIV-1 proteins are encoded by the 4-plasmid combination that composes the 3rd generation LVV transduction systems. LVVs use HIV-1-like mechanisms for viral genome integration and both transgene delivery and expression. LVVs rely on host cell machinery to transcribe and translate transgenes for either knocking down disease-causing genes and/or supplying functional genes in a targeted disease. LVVs integrate into host intronic and intergenic regions due to genomic accessibility, but there are no known biases toward specific target integration motifs. Investigation of LVV integration has uncovered the generation of chimeric LVV-host transcripts and altered host transcript splicing patterns. Several Food and Drug Administration (FDA)-approved LVV-derived therapies are used for treating diseases ranging from beta thalassemia to sickle cell anemia. An increasingly popular application of LVV is in the generation of chimeric antigen receptor (CAR) T cell therapies, which change and enhance T cell antigen specificity and effector function in liquid cancers. In November 2023, all CAR T cell therapies were placed under FDA investigation due to higher-than-expected rates of malignant transformation, hospitalization, and death in treated individuals. LVV integrations driving oncogene expression could be a cause for malignancy development. Current methods for resolving LVV integration patterns are technically limited by the sequencing approach applied allowing for only limited characterization of LVV integration profiles and altered host gene regulation. A comprehensive understanding of LVV integration and its consequences is necessary for understanding how these events influence host cell gene regulation and splicing, possibly identifying tunable variables for enhanced positive clinical outcomes. Here, we review the development of LVV systems, what is known about LVV integration patterns, technologies used to characterize patterns of LVV integration, and what is understood about the subsequent impact on host cell gene regulation and its potential linkage to patient malignancies."

Despite early promise, clinical adoption of IVM has been limited due to lower embryo developmental competence and live birth rates compared to IVF. However, recent advances in the understanding of oocyte physiology, including cumulus-oocyte communication, the regulatory roles of cAMP/cGMP signaling pathways, and endocrine modulation of meiotic resumption, have reignited interest in optimizing IVM protocols. Innovations such as biphasic Capacitation (CAPA) IVM systems and the use of ovarian somatic support cells (OSCs) derived from induced pluripotent stem cells (iPSCs) aim to replicate the dynamic follicular environment more accurately and enhance oocyte competence. Clinical studies suggest that, while IVM still results in modestly lower cumulative live birth rates compared to conventional IVF, it offers significant advantages for selected patient populations, particularly women with polycystic ovary syndrome (PCOS), high ovarian reserve, or those requiring fertility preservation. Importantly, current evidence supports the genetic and epigenetic safety of IVM-derived offspring.

A case is made for coordinated, technology-neutral regulatory change. The article proposes the principles of a model UK Human Reproductive and Developmental Biotechnology Act and regulator, the Human Reproductive and Developmental Biotechnology Authority-or HRBA, pronounced 'harbor'-to provide a permissions route across research and translation. The model Act is a modular, risk-tiered scheme with consistent standards and tailored red lines. It is designed to accommodate boundary cases, to integrate and build upon the existing remit of the Human Fertilisation and Embryology Authority, and coordinate with other established regulators to retain institutional expertise and avoid unnecessary duplication. The proposal is ambitious and would help give effect to UK Government commitments to safely advance the life sciences in this area. But even if piecemeal amendments are ultimately favored, it clarifies the underlying choices and trade-offs and provides a benchmark against which changes can be tested."

This review synthesizes current advances aimed at enhancing the specificity of CRISPR diagnostics, with particular emphasis on the pivotal role of CRISPR RNA (crRNA) engineering. We detail how structural determinants of crRNA, including spacer length optimization, intentional mismatch design, secondary-structure modulation, chemical modification, strand-displacement gating, and synergistic design frameworks, govern CRISPR-mediated target recognition and define the energetic and kinetic thresholds for accurate cleavage. Key engineering strategies encompassing computational prediction and modeling, high-throughput screening, and hybrid guide architectures are systematically examined for their capacity to elevate single-nucleotide discrimination, stabilize reaction performance, and enable robust multiplexed detection for pathogen profiling and mutation identification. Despite rapid progress, outstanding challenges persist, including interference from complex clinical matrices, lack of unified evaluation standards, and scalability barriers that hinder clinical translation. Addressing these limitations through integrated crRNA design, system-level optimization, and standardized benchmarking will be essential for realizing the promise of CRISPR diagnostics. Ultimately, these advances are poised to support ultrasensitive, highly specific, and portable point-of-care testing, thereby accelerating precision medicine and strengthening infectious disease surveillance and management."

Although ssODN sequence fidelity is critical to the safety and efficacy of editing, standard quality control methods cannot resolve individual nucleotide errors. Methods: We performed deep sequencing of ssODNs from three manufacturers and amplicons from edited hematopoietic stem/progenitor cells. Results: We find that synthesis errors are present in all ssODNs tested at rates that vary more than two-fold among manufacturers, at positions that are dependent on sequence context. These synthesis errors are propagated into the genome by HDR at frequencies proportional to their abundance in the ssODN. In our sickle cell mutation correction protocol, the most prevalent SNEs are predicted to produce benign \u03b2-globin variants, while the less frequent frameshift deletions are predicted to generate \u03b2-thalassemia-like alleles. Conclusions: Current quality control standards are insufficient to detect these errors, and deep sequencing of ssODNs should be incorporated into regulatory submissions for clinical gene editing programs."

Prime editing enables precise genome modification without generating double-strand DNA breaks or requiring donor DNA templates. We established an in vitro prime editing workflow to generate and subsequently correct the mdx5cv mutation in mouse C2C12 myoblasts. Following optimization of engineered prime editing guide RNAs (epegRNAs) and PAM-flexible prime editors, wild-type cells were edited, clonally isolated, and genotyped. Mutation correction was then evaluated using optimized epegRNA designs. Two rounds of prime editing introduced the mdx5cv mutation into approximately 20% of alleles in C2C12 cells creating the mdx5cv C2C12 cell line. Clonal isolation yielded five homozygous mutant clones among 59 expanded colonies. Optimization studies identified an epegRNA containing a 16 nucleotide reverse transcription template and a 10 nucleotide primer binding site (RTT16/PBS10) as the most efficient design. Correction of the pathogenic allele reached approximately 26%, whereas longer PBS lengths reduced editing efficiency. In silico off-target analysis using Cas-OFFinder identified no candidate genomic loci with fewer than three mismatches for the spacer sequences used in either mutation generation or correction, suggesting a favorable predicted specificity profile. Corrected mdx5cv C2C12 myoblasts retained their capacity to differentiate into multinucleated myotubes. Representative Western blot analysis detected dystrophin protein expression in differentiated corrected mdx5cv myotubes, consistent with successful correction of the pathogenic mutation. These findings establish a robust prime editing platform for both the generation and correction of the mdx5cv mutation and provide proof of concept that precise correction of the pathogenic mutation is associated with restoration of dystrophin expression following myogenic differentiation."

These K27M mutations shape intratumoral myeloid cell composition in DMG. In H3.1K27M DMGs, genetic ablation of monocyte recruitment reshapes the tumor microenvironment (TME) by reducing monocyte-derived macrophages (MDMs) and increasing microglia and neutrophil presence, with overall survival remaining unchanged, indicating compensatory myeloid remodeling is occurring. Here, by using CRISPR/Cas9-based genome editing, we generated a mouse model deficient for CCR1/CCR2/CCR3/CCR5 (\u03941235). Using this strain, we effectively abolished monocyte and MDM infiltration and reversed compensatory recruitment of CCR1+ neutrophils. Abolishing MDMs in tumors skewed remaining neutrophils and microglia toward a homeostatic state, reduced expression of immune checkpoint molecules on T cells, and extended the survival of H3.1K27M DMG-bearing mice. In contrast, H3.3K27M DMG showed independence from MDM recruitment, suggesting reliance on other TME-driven signaling. Last, H3.1K27M DMGs exhibited reduced microglia presence and a dose-dependent increase in MDM infiltration postirradiation. MDM depletion did not further enhance radiation efficacy, potentially due to compensatory recruitment of classical neutrophils. Collectively, these data reveal histone mutation-specific myeloid dependencies in DMG, highlighting MDM-independent mechanisms in H3.3K27M tumors and MDM-dependent pathways in H3.1K27M tumors."

"abstract_text": "ID: 42327050\nTitle: Attenuated estrogen signaling disrupts placentation and drives trophoblast defects in Down syndrome.\nAbstract: Proper establishment of the primitive placenta and subsequent tissue homeostasis in the mature placenta are critical for successful pregnancy in humans. Placental insufficiency is associated with adverse pregnancy outcomes, including fetal growth restriction, preeclampsia, and pregnancy loss. Moreover, emerging evidence suggests that placental defects are associated with long-term health challenges that manifest well into adulthood; yet the etiologies of such diseases are largely unknown. Defining the mechanistic basis for placental deficiencies, therefore, has important implications for improving both reproductive health and the lifelong well-being of affected children. Down syndrome is characterized by placental defects of unknown mechanistic origin, and notably, individuals with Down syndrome are at increased risk of developing diseases commonly associated with placental insufficiency later in life. Using induced pluripotent stem cells from Down syndrome patients, we found that stem cell-based embryo models (i.e., blastoids) and directed differentiation systems recapitulate trophoblast cell fate defects observed in placentas affected by Down syndrome. Furthermore, we demonstrate that attenuated estrogen signaling contributes to placental syncytialization defects and identify NRIP1, a transcriptional corepressor of estrogen receptor that is located on chromosome 21, as a key driver of trophoblast cell fate defects. Increased gene dosage of NRIP1 in an otherwise diploid cell line phenocopies cell fate defects observed in trophoblasts affected by Down syndrome. Our study suggests that estrogen signaling is a crucial regulator of trophoblast development and may serve as a potential target for therapeutic intervention.

In our previous work, TNFRSF13B exon 2 variants were recurrently identified in chronic active Epstein-Barr virus disease (CAEBV). Here we aim to reveal the roles of TNFRSF13B variants in CAEBV, and investigate the feasibility of targeting TNFRSF13B/TACI as a new approach to control EBV infection. The lymphoblastoid cell lines (LCL) models carrying homozygous TNFRSF13B exon 2 frameshift mutations were constructed using CRISPR/Cas9. Immunological assays, transcriptomic analysis, and gene silencing experiments were performed on LCL models to measure the effect of TNFRSF13B exon 2 variants and explore the underlying mechanisms. TACI ligands and a TLR9 agonist were applied to modulate TACI signaling and EBV activities. Frameshift mutations in exon 2 of TNFRSF13B significantly up-regulated the short isoforms of TACI (TACI-S) at the expense of its long isoforms (TACI-L) in LCLs. The up-regulated TACI-S induced more intense activation of NF-\u03baB, MAPK, and Rho signaling pathways, leading to the switch of EBV activities to lytic reactivation. The subsequent increased viral load and viral IL-10 provide a rational for the susceptibility of variant carriers to CAEBV. The BAFF trimer, an indirect TACI-signaling inhibitor, also significantly suppressed the EBV lytic program. Gene silencing experiments indicated that XBP-1 might be involved in the TACI-mediated regulation of EBV lytic activities in EBV-immortalized B cells. This study underscores the impact of TNFRSF13B variants on EBV infection and host immune responses, offering insights into CAEBV pathogenesis and potential therapeutic strategies."

In this study, we analyzed 647 Danish patients with suspected myeloid neoplasms to assess the frequency of germline DDX41 variants and the functional impact of variants of uncertain significance (VUSs) using a cell-based assay, CRISPR-Select. We identified 16 DDX41 variants in 30 patients, 14 of whom were confirmed or predicted as germline variants. Eight germline variants were classified as likely pathogenic/pathogenic (LP/P), and three as VUSs. We generated a monoallelic DDX41 K562 cell line and used it for CRISPR-Select assessment of variant effects on proliferation and survival. Pathogenic variants impaired proliferation, while benign variants did not. Missense variants had a more subtle effect than truncating ones, suggesting hypomorphic phenotypes. One DDX41 VUS had a significant negative effect on proliferation, suggesting it to be pathogenic, while the other two had no effect, suggesting them to be benign.

Although gap larvae exhibit normal external morphology, gap mutants exhibit severe defects in adult organs, suggesting that the gap gene is required for the development of imaginal discs and the primordia of adult organs. Genetic analysis of the gap mutation provides an opportunity to understand the molecular mechanisms underlying the development of adult organs. In this study, we performed RNA-seq analysis of ovaries from gap mutants. De novo assembly of RNA-seq reads identified the insertion of a retrotransposon in the gene encoding the Bombyx ortholog of protein-cysteine N-palmitoyltransferase (Rasp), which is required for Hedgehog signaling in Drosophila. PCR and subsequent sequencing analyses revealed that an LTR transposon is inserted into exon 1 of the BmRasp gene. To verify the involvement of BmRasp in the gap phenotype, we generated a knockout allele of BmRasp (BmRaspKO) using the CRISPR/Cas9 system. Both homozygous knockout mutants and F1 pupae with the gap/BmRaspKO genotype exhibited gap-like phenotypes characterized by apterous pupa, indicating that BmRasp corresponds to the gap locus. To investigate why zygotic BmRasp expression is dispensable during embryogenesis but essential for the development of adult organs, we analyzed BmRasp expression levels in eggs and larval tissues. Furthermore, testis transplantation experiments demonstrated that BmRasp is dispensable for spermatogenesis, despite the fact that the testis exhibits the highest expression level of BmRasp among the tissues analyzed. Finally, we discuss the physiological roles of Hedgehog signaling in embryogenesis and in the development of imaginal discs in B. mori."

However, the path to this milestone reveals a pattern of MSCs failing in late-phase clinical trials. Multiple sources of heterogeneity may explain these results, including variability in donor and recipient biology, product manufacturing and characterization, and trial design. For example, certain subsets of acute GVHD patients, particularly those with inflammatory/immune activation, may derive the greatest clinical benefit from MSCs. Trials failing to stratify for this patient-level heterogeneity risk failure while obscuring signals of efficacy in responsive subgroups. Improving trial design considering heterogeneity requires leveraging advances in MSC manufacturing and refining clinical trial methodologies. The development of pooled and early-passage MSCs, induced pluripotent stem cell-derived (iPSC)-MSCs, biomaterial-encapsulated MSCs, and gene-edited or chimeric antigen receptor-expressing MSCs may reduce heterogeneity and improve trafficking to and survival at disease sites. Equally important, trial methodologies must explicitly address heterogeneity from MSC manufacturing and patient enrollment.

This review systematically summarises current fabrication strategies, disease-modelling utilities and regenerative potentials of liver organoids, alongside the major challenges and future directions. In recent years, the field has witnessed several breakthroughs. Through endothelial co-culture approaches, vascularised and metabolically zonated liver organoids have been successfully generated, achieving endothelial coverage exceeding 85%. Prime editing enables precise correction of pathogenic mutations in patient-derived organoids, with no off-target effects detected at the genome-wide level. In disease modelling, iPSC-derived liver organoids faithfully recapitulate the pathological progression of metabolic dysfunction-associated steatotic liver disease (MASLD) and verify the lipid-lowering efficacy of semaglutide. Macrophage-integrated organoid models support the full life cycles of HEV, SARS-CoV-2 and dengue virus, providing new tools for antiviral drug screening. Large-scale patient-derived tumour organoid biobanks successfully preserve the heterogeneity and clinical drug-resistance signatures of liver cancers. In regenerative medicine, encapsulated hepatocyte organoids and the UTOpiA bioartificial liver system have effectively rescued acute liver failure in animal models, while gene-edited autologous organoids offer potential curative strategies for genetic disorders such as Wilson disease. Nevertheless, insufficient hepatocyte functional maturity, difficulties in constructing vascular networks, and the lack of standardised culture protocols remain major obstacles to clinical translation. By bridging fundamental liver biology and clinical practice, liver organoid technology lays a solid foundation for precision hepatology and regenerative therapies. Continued interdisciplinary efforts are still required to overcome current limitations and facilitate its clinical adoption."

Reliable generation of defined neuronal populations, such as gamma-aminobutyric acid (GABAergic) neurons, is essential for these studies. This protocol details a robust method for differentiating hiPSCs into GABAergic neurons using a doxycycline-inducible system. The approach relies on the stable integration of transgenes encoding the transcription factors ASCL1 and DLX2 into the safe-harbor adeno-associated virus integration site 1 (AAVS1.) locus via CRISPR/Cas9-mediated knock-in. This targeted integration avoids the transgene silencing often observed with random lentiviral integration. The protocol covers the maintenance of hiPSCs, the nucleofection process for transgene integration, puromycin selection to enrich successfully engineered cells, and the step-by-step differentiation procedure. Upon induction with doxycycline, the engineered hiPSCs rapidly exit the cell cycle, acquire neuronal morphology, and express GABAergic lineage markers within 21 days. Key steps include neuro-induction and subsequent maturation using specific growth factors, as well as potential approaches to improve cellular adhesion during maturation. This standardized method yields enriched populations of induced neurons expressing GABAergic lineage markers, providing a valuable tool for neuroscience research and cellular modeling."

Here, we establish the first comprehensive human mechanistic model of PPP1R9A haploinsufficiency using an isogenic CRISPR/Cas9-engineered iPSC system differentiated into cortical neurons to define dosage-dependent functional consequences. PPP1R9A+/- neurons exhibited pronounced hyperspinogenesis and increased neuritic complexity, indicative of aberrant structural maturation; however, whole-cell patch-clamp recordings revealed impaired intrinsic excitability, including reduced action potential firing, altered waveform properties, and defective axo-somatic coupling, uncovering a striking dissociation between neuronal morphology and function. Long-read single-cell transcriptomics and quantitative proteomics identified coordinated downregulation of ion channel and synaptic transmission pathways, including genes essential for sodium channel function and glutamatergic signaling, together with disruption of synaptic vesicle cycling, axon guidance, and neurodevelopmental programs. Pseudotime trajectory analysis further demonstrated delayed neuronal differentiation, with mutant neurons accumulating at intermediate developmental states rather than acquiring mature cortical identities. Importantly, molecular rescue experiments confirmed causality, as restoration of full-length PPP1R9A expression robustly normalized transcriptional and synaptic signaling programs, whereas allele-specific antisense oligonucleotide-mediated suppression of the mutant transcript achieved only partial rescue. Taken together, these findings establish PPP1R9A haploinsufficiency as a driver of impaired molecular, electrophysiological, and developmental maturation in human cortical neurons, providing a human-specific mechanistic framework linking reduced Neurabin I dosage to neurodevelopmental and psychiatric disease risk."

In this study, the BCH gene in Nicotiana tabacum was targeted using CRISPR/Cas9 genome editing to redirect metabolic flux toward \u03b2-carotene accumulation and evaluate its effects on heat tolerance. Following Agrobacterium-mediated transformation with a BCH-specific gRNA, three mutant plants were obtained; two carrying frameshift mutations (P1 and P3) and one with mis-sense mutations (P2). A significant increase in chlorophyll contents was observed in the edited lines compared with wild-type plants. Interestingly, the frameshift mutants exhibited substantial increase in total chlorophyll (71% and 31% in P3 and P1 respectively) as compared to mis-sense mutant P2 (18%). Further, biochemical profiling using HPLC showed that the edited plants accumulated 3.74-fold increase in \u03b2-carotene than wild-type plants. Under heat stress (42\u202f\u00b0C for 96\u202fh), the edited plants exhibited enhanced thermotolerance by remaining greener and delayed wilting, whereas wild-type plants developed necrosis rapidly under heat stress. This enhanced thermotolerance might has resulted from the increased expression of \u03b5-cyclase (an upstream key enzyme in \u03b2-carotene biosynthesis) as revealed by expression profiling of edited plants. In contrast, the expression of downstream \u03b2-cryptoxanthin and zeaxanthin biosynthetic genes was reduced, which seems consistent with mutation of BCH. DAB staining further confirmed reduced ROS accumulation in edited plants as compare to wild type supporting the protective role of \u03b2-carotene. In summary, the downregulation of BCH in N. tabacum boosted \u03b2-carotene levels and chlorophyll retention, enhancing heat stress tolerance.

Initial treatment with standard therapy, surgery, radioactive iodine, the thyroid-stimulating hormone inhibition and in some cases, chemotherapy or external-beam radiations are effective with the differentiated cancers at the early stages. Nevertheless, there is no choice with tumours, which become unresponsive to iodine, metastasized, or un- differentiated. Recent developments in molecular oncology have elucidated the genetic alterations that contribute to thyroid cancer, in particular, the MAPK and PI3K/AKT/mTOR pathways, and BRAF, RAS, RET, and TERT promoter mutations. The current review summarizes the changing therapeutic environment of thyroid cancer that includes established targeted medicines and novel developments. These are immune checkpoint inhibitors, redifferentiation based on reinstatement of iodine uptake, selective RET and BRAF/MEK, RNA-based therapeutics, CRISPR gene editing, oncolytic virotherapy, peptide receptor radionuclide therapy, alpha-particle radiotherapy, and nanotechnology-based drug delivery systems. A combination regimen involving molecular targeting and immunotherapy or radioactive iodine is also improving the disease in advanced disease. Collectively, the advances are an indication of a transition to the personalized, mechanism-driven treatment strategies that would prolong the survivability of patients with advanced thyroid cancer, conquer resistance, and reduce systemic toxicity."

(Lepidoptera: Bombycidae).\nAbstract: The Bombyx mori L. (Lepidoptera: Bombycidae) is a significant economic insect used for silk production. A novel body shape mutant, stony^sunken (st^sk), that exhibits a sunken intersegmental membrane was isolated from the wild type of st^sk (WT-n08). Investigation indicated that the mutation had no significant effect on its growth and development. To elucidate the molecular mechanism underlying this body shape mutant, genetic analysis, positional cloning, and the CRISPR/Cas9 gene editing system were performed. Genetic analysis demonstrated that the mutant trait in st^sk is controlled by an autosomal recessive gene and follows Mendelian inheritance. Positional cloning showed that a putative cuticular protein gene, BmorCPR2 on chromosome 8, was the candidate gene. Sequencing analysis revealed partial deletion of BmorCPR2 exon 2 and intron 2 sequences occurred and subsequently resulted in the premature termination of gene expression. Knock-out of BmorCPR2 using the CRISPR/Cas9 gene editing system led to the sunken intersegmental membrane phenotype. These findings highlight the essential role of BmorCPR2 in silkworm cuticular formation, providing a foundation for further research on cuticular protein function."

Here we study APP specifically in the context of Trisomy 21. In an effort to reduce APP dosage in trisomy 21 iPSCs, we generated trisomic isogenic lines which vary in APP dosage, including a full APP knock-out line, as well as lines carrying mutations of the APP extracellular domain. We used a panel of these lines to study potential impacts of APP dosage or structure on two distinct steps of neurogenesis in trisomic cells: 1) terminal differentiation of human neuro-progenitor cells (NPC) to post-mitotic neurons and 2) neuron structure as reflected in neurite outgrowth. Complete loss of APP causes marked defects in each of these two distinct steps, reducing both the terminal differentiation of NPCs to neurons, and proper neurite development for extended neuron structure. Hence, APP is necessary for both aspects of normal neurogenesis. Further analyses of the null and other mutant lines indicate that APP likely impacts these two distinct steps by two different mechanisms. Collective results suggest that the reduced terminal differentiation of NPCs reflects an effect of APP dosage, whereas the defects in neurite extension are due to structural mutation of the APP extracellular domain. Absence of APP or reduced (monosomic) APP dosage prolonged the cycling of trisomic NPCs, which is known to be regulated by Notch signaling. APP and Notch are the main targets of gamma-secretase cleavage, hence we hypothesized that APP dosage may impact neurogenesis indirectly, potentially via effects on Notch signaling. To test this, we treated NPCs with Compound E which inhibits gamma-secretase (and Notch signaling); results show this restored levels of neurogenesis in APP depleted lines, supporting an indirect effect of APP dosage . In contrast, results indicate that disruption of APP extracellular domain integrity impacts neurite extension via a more direct role of APP in neuron structural maturation. This study describes a resource of well-characterized APP mutant isogenic DS iPSC lines, implicates a dynamic interplay between APP dosage and Notch signaling, and raises new questions about the impact of APP dosage in orchestrating neural progenitor fate decisions during human brain development, specifically in the context of trisomy 21."

Taking advantage of the single-guide RNA (sgRNA) and protospacer adjacent motif (PAM) sequence (3'-NGG) specificity of the Cas9 protein in the CRISPR/Cas9 (Clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9) system and codon degeneracy, the authors design a repair template that incorporates the desired point mutation while excluding the PAM sequence disrupted by a synonymous substitution, thereby preventing re-cleavage by CRISPR/Cas9. This method employs two available plasmids, pCasKP-apr and pSGKP-spe, offering straightforward operation and high screening specificity. As a result, the approach enables efficient generation of genetically defined mutant strains of Klebsiella pneumoniae (K. pneumoniae) and is readily adaptable to routine laboratory settings. Furthermore, the protocol minimizes off-target editing, shortens experimental timelines, reduces screening workload, and provides a reliable platform for investigating resistance mechanisms, validating candidate genes, and supporting functional genomics studies in clinically relevant bacterial pathogens."

However, traditional microinjection methods for RNP delivery in insect embryos are labor-intensive, technically demanding, and often reduce embryo viability, especially in species with fragile, microscopic embryos. In this study, a novel, non-invasive delivery method for the RNP complex in tiny insect embryos has been optimized. Whitefly, Bemisia tabaci, an invasive insect pest of agricultural importance and vector of plant diseases, was considered as a model organism. A needleless dechorionation-permeabilization method was employed to deliver the RNP complex to the early embryonic stage of B. tabaci embryos. B. tabaci heat shock protein 70 (hsp70) gene, which interacts with the begomovirus coat protein, aiding in its internalization and successful transmission by B. tabaci in a persistent circulative manner, was targeted for knockout. Two sgRNAs were synthesized via in vitro transcription, and the Cas9-sgRNA complexes were validated by in vitro cleavage assays. The localization of the GFP-labelled Cas9-sgRNA complex confirmed successful RNP delivery, as observed through confocal microscopy. A survival rate of 18% of the embryos was recorded post-RNP delivery. Sequencing of treated embryos showed 25- and 28-nucleotide deletions in the hsp70 exon. Synthego ICE analysis revealed up to 84% gene knockout efficiency. This method enables batch processing of embryos, drastically reducing delivery time and associated costs while improving throughput. Hsp70 KO B. tabaci mutants generated in the study are expected to be incompetent begomovirus transmitters, which would help restrict the spread of the virus. Our study overcomes a key bottleneck in CRISPR/Cas delivery to small insect embryos, opening new avenues for rapid, high-throughput, and cost-effective RNP delivery methods in insect embryos. The novel non-invasive methods would be helpful in the deployment of gene editing for sustainable pest control."

Francisella novicida Cas9 (FnCas9) exhibits high intrinsic specificity but is constrained by stringent PAM requirements. Here, we quantitatively examine the energetic and catalytic consequences of PAM-interacting mutations in three engineered variants, en1 (E1369R), en15 (E1603H), and en31 (G1243T/E1369R/E1449H), using a VEGFA3 DNA substrate framework. Microscale thermophoresis and isothermal titration calorimetry reveal that the engineered variants enhance binding affinity toward the canonical NGG PAM relative to wild-type FnCas9, with modest gains in binding free energy. Selected noncanonical PAM substrates, particularly TGA and TAG, also show improved binding by en15 and en31, with en31 displaying the strongest overall binding among the substrates tested. Thermodynamic profiles indicate that enhanced affinity is associated with more favorable enthalpic contributions, consistent with altered interactions at the PAM interface; however, the specific molecular contributions underlying these changes remain to be directly established. Despite improved binding, active-site titration reveals reduced fractions of catalytically competent enzyme in engineered variants, particularly en31, necessitating higher enzyme concentrations to achieve cleavage efficiencies comparable to wild-type. Cleavage assays demonstrate that en31 most effectively couples improved recognition of the tested noncanonical PAM substrates to productive catalysis, enabling robust cleavage of both TGA and TAG substrates while maintaining minimal off-target activity under the conditions examined. Together, these results suggest that PAM-interacting mutations in FnCas9 can alter the energetic coupling between DNA binding and catalytic activation within the VEGFA3 substrate framework tested, highlighting the importance of balancing substrate affinity with conformational activation in the design of high-precision genome-editing nucleases."

MicroRNAs (miRNAs) have emerged as an essential post-transcriptional regulator of host-virus interactions, influencing viral replication, immunological responses and disease progression. This review offers a comprehensive overview of the miRNA-virus axis in RNA virus infections, highlighting the dynamic and context-dependent roles of host miRNAs. We investigate the mechanistic basis of miRNA-mediated regulation, including direct targeting of viral RNA, modulation of host dependency factors, regulation of antiviral signaling pathways, and immune-mediated effects on infection outcomes. We propose a functional categorization of miRNAs that transcends the conventional antiviral-proviral dichotomy, facilitating a more accurate comprehension of their involvement in various infection settings. This review connects mechanistic insights with translational applications by outlining novel treatment techniques, such as miRNA mimics, anti-miRs, RNA interference, and CRISPR-based methodologies. We also propose a therapeutic decision framework that links miRNA functional classification with targeted antiviral interventions. Key challenges including delivery efficiency, tissue specificity, and off-target effects are also discussed, with emphasis on lipid nanoparticles and exosome-based delivery systems. We further highlight the role of systems biology approaches, including multi-omics integration, single-cell and spatial transcriptomics, network analysis, and artificial intelligence, in identifying regulatory miRNA hubs and enabling precision antiviral medicine. Collectively, this review reinterprets the miRNA-virus axis as a dynamic regulatory network and provides a translational framework for the development of next-generation antiviral therapeutics."

In this study, we established a highly sensitive and specific assay by combining peptide nucleic acid (PNA)-mediated PCR clamping with CRISPR/Cas13a trans-cleavage detection. A PNA probe targeting the wild-type (WT) EGFR T790M allele was designed to suppress WT amplification during PCR, while minimally affecting mutant allele amplification. By combining the target specificity of Cas13a for mutant alleles with the WT-suppression capability of PNA-PCR, we achieved a dual-enrichment effect for mutant detection. When applied to EGFR T790M mutation detection, the assay reached an analytical sensitivity of 0.02%. We established a standard curve for T790M detection using cell-free DNA standards. Clinical validation in 20 plasma samples from lung adenocarcinoma patients demonstrated that the PNA-Cas13a assay achieved a diagnostic sensitivity of 93.3% (95% CI: 68.1%-99.8%) and a specificity of 100% (95% CI: 47.8%-100%), with detection concordance comparable to or improved over ARMS-PCR in this pilot cohort. The results suggest its preliminary diagnostic utility in liquid biopsy. In conclusion, the PNA-Cas13a assay enables sensitive and specific detection of EGFR T790M mutations in ctDNA, is readily adaptable to multiple gene loci, and holds promise for clinical monitoring of tumor drug resistance."

We previously identified RNA viruses that infect the nematodes C. elegans and C. briggsae in a species-specific manner. Wild strains of both host species demonstrate ample variation in viral sensitivity. Here we use recombinant inbred lines and pool-sequencing approaches to genetically map a major resistance locus in the C. elegans MY10 strain, narrowing down its position by CRISPR/Cas9 mediated recombination and testing candidates by genome editing. A rare non-synonymous polymorphism in the gtnt-1 gene, encoding a putative glycosyltransferase of the GT92 family, causes resistance to viral infection in MY10. Loss-of-function gtnt-1 alleles conferred host protection only at late developmental stages, highlighting the importance of multigenerational assays capturing the full course of viral infection and transmission. Viral resistance through gtnt-1 mutation occurred repeatedly in C. elegans, with diverse alleles each remaining at low frequency (<1%). Furthermore, leveraging closely related C. briggsae strains differing in viral susceptibility, we find that repeated loss-of-function alleles of the Cbr-gtnt-1 ortholog similarly enhanced resistance and host fitness upon infection. In conclusion, recurrent evolution in two host species of loss-of-function alleles of gtnt-1 orthologs leads to viral resistance. The gtnt-1 gene being conserved between Caenorhabditis species, these repeated inactivation events provide a case of transient ecological adaptation to a pathogen through recurrent mutation of the same gene in two species. The low population frequencies of resistant alleles point to a changing eco-evolutionary context that prevents their spread in populations."

Rhesus induced pluripotent stem cells (RhiPSCs) derived from these monkeys present a unique opportunity for in vitro modeling and comparison with cells derived from MAPT R406W human carriers. Here, we report the development of a reproducible method to generate RhiPSCs compliant with the standards of the International Society for Stem Cell Research (ISSCR) to support in vitro modeling of FTD-MAPT R406W. Our stepwise approach identified efficient methods for fibroblast derivation, fibroblast reprogramming to RhiPSC, and RhiPSC maintenance over continued culture. To derive fibroblasts from MAPT wild type (WT) and R406W monkeys, a combination of manual processing and overnight enzymatic digestion was required to maximize the number of low passage fibroblasts available for reprogramming. Fibroblast reprogramming to RhiPSC using Sendai viral vectors versus oriP/EBNA1 episomal plasmids revealed the latter as most efficient. Electroporation conditions for oriP/EBNA1 reprogramming were optimized to maximize plasmid uptake and cell survival. Ultimately, eight RhiPSC lines were derived from 4 donor rhesus monkeys (n = 2 WT, n = 2 R406W; two clonal lines per donor) and fully characterized according to ISSCR standards. RhiPSC stemness and genetic stability was best maintained on mouse embryonic fibroblast feeders in Universal Primate Pluripotency Stem Cell medium, as opposed to Essential 12 medium supplemented with IWR1, which produced cytogenetic abnormalities. Rhesus neural progenitor cells were generated using a monolayer protocol and expressed PAX6 and NESTIN after 21 days of differentiation. Our reliable method will be useful to labs seeking to derive RhiPSCs for preclinical studies. Overall, the RhiPSCs generated from MAPT R406W carriers will be a critical resource for evaluating the molecular underpinnings of tau-related neurodegeneration across primate species."

Intrinsic resistance is largely driven by the low permeability of the mycobacterial cell envelope, the activity of efflux pumps, and the presence of drug-modifying enzymes, which together restrict intracellular drug accumulation and contribute to broad baseline tolerance. This review integrates resistance mechanisms of both M. tuberculosis and M. abscessus, two clinically relevant mycobacteria that share core molecular pathways while exhibiting species-specific determinants that complicate treatment. Additional intrinsic factors, including biofilm formation and stress-induced adaptive responses, further enhance persistence and reduce susceptibility to multiple drug classes. Acquired resistance predominantly results from chromosomal mutations affecting drug targets or prodrug activation pathways, such as katG, inhA, rpoB, gyrA, and pncA in Mycobacterium tuberculosis, leading to high rates of multidrug-resistant and extensively drug-resistant disease. In nontuberculous mycobacteria, species-specific determinants-including inducible macrolide resistance mediated by erm(41) in M. abscessus, plasmid-mediated erm (55) variants, rrl and rrs mutations, diverse enzymatic inactivation systems, and regulatory alterations in the MarR family that result in inducible resistance to drugs such as ethionamide -generate highly variable resistance profiles that complicate treatment. Recent advances in molecular diagnostics, including PCR-based assays, whole-genome sequencing, CRISPR-based diagnostic platforms, AI-assisted diagnostics, and emerging multi-omics approaches, have improved the detection of resistance-associated mutations and enhanced understanding of mycobacterial pathophysiology. In parallel, new therapeutic agents and optimized regimens offer promising avenues to overcome resistance, although emerging resistance to novel drugs underscores the need for continued surveillance. This review synthesizes current knowledge on the molecular basis of resistance in M. tuberculosis and NTM, highlighting implications for diagnosis, treatment, and future research."

These conditions are characterized by impaired cholesterol synthesis together with the accumulation of disease-specific sterol intermediates. Current experimental and clinical evidence suggests that pathogenesis reflects both cholesterol insufficiency and sterol-mediated toxicity, including oxidative stress, perturbed developmental signaling, membrane dysfunction, and impaired neurodevelopment. Experimental models have played a central role in elucidating these mechanisms and in evaluating emerging therapeutic strategies. This review provides a comprehensive overview of currently available experimental models used to investigate inherited cholesterol biosynthesis disorders, including genetically engineered animal models, patient-derived fibroblasts, immortalized and CRISPR/Cas9-edited cell lines, and induced pluripotent stem cell-based systems.

No approved therapy restores myocardium lost to infarction. The adult heart replaces cardiomyocytes at approximately 1% per year in young adults, declining to about 0.45% per year with ageing, far below what is needed to recover the more than one billion cells destroyed by a large myocardial infarction. Cell-based regenerative strategies have been investigated for more than two decades, encompassing bone marrow mononuclear cells (BM-MNCs), mesenchymal stromal cells (MSCs), cardiac progenitor cells, cardiosphere-derived cells (CDCs), skeletal myoblasts, and induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs). Safety has been consistent. Efficacy has been modest and variable: the CADUCEUS trial demonstrated scar mass reduction with CDCs without proportionate ejection fraction improvement; the Phase 1/2 POSEIDON trial confirmed MSC safety in 30 patients; and the Phase 3 DREAM-HF trial, enrolling 537 patients, failed its primary endpoint (HR 1.2, p = 0.406). Mechanistic work has established that transplanted cells engraft poorly and exert their benefit principally through paracrine signalling mediated by secreted extracellular vesicles and exosomes carrying microRNAs, trophic factors, and immunomodulatory proteins. For iPSC-CMs, electrophysiological immaturity and arrhythmogenic risk in primate models remain unresolved barriers. Emerging strategies include CRISPR-engineered hypoimmune iPSC lines, bioengineered cardiac patches, injectable hydrogel scaffolds, and engineered exosome platforms. This review provides a comprehensive synthesis of preclinical and clinical evidence, examines translational barriers, and identifies the scientific and regulatory priorities required before these therapies can enter routine clinical practice."

At the same time, several promising approaches targeting fetal hemoglobin induction, iron metabolism, and ineffective erythropoiesis have failed to demonstrate sufficient clinical benefit despite preclinical proof of concept, highlighting the complexity of therapeutic development in \u03b2-thalassemia. Future priorities include refining patient selection, generating real-world and comparative effectiveness data, developing clinically meaningful response criteria, expanding pediatric access, and addressing the substantial cost and accessibility challenges associated with novel therapies."

This study evaluates the extent of genetic mosaicism resulted from CRISPR-Cas9-mediated knockout for 11 genes in the freshwater microcrustacean Daphnia magna, D. pulex, and D. sinensis. Based on extensive genotyping data of the asexually produced progenies of successfully edited females, we find strong evidence of mosaicism in 9 of these genes. The genotyping data also suggest the gene editing activity can take place as early as the one-cell embryo stage and extends into the 32-cell and later stages. This study establishes genetic mosaicism as an important feature of Cas9-mediated gene editing in Daphnia."

Beyond direct cytotoxicity, this photochemistry can be repurposed for on-demand cargo release from lipid nanocarrier systems, enabling spatiotemporal control over therapeutic delivery that is not achievable with conventional lipid nanoparticles. This protocol presents methods for fabricating and characterising two distinct verteporfin (VP)-integrated lipid nanoparticle formulations: (1) light-triggered liposomes composed of DOTAP, DOPE, cholesterol, and VP for delivery of CRISPR-Cas9 ribonucleoprotein (RNP) complexes; and (2) X-ray-triggered liposomes composed of DOTAP, DOPC, VP, and gold nanoparticles for controlled chemotherapy drug release. Upon activation at 690 nm (visible light) or by clinical X-ray radiation (6 MeV), VP generates singlet oxygen that oxidises unsaturated lipid components, destabilising the nanoparticle membrane and releasing encapsulated cargos. Protocols are provided for liposome formulation by thin-film hydration and membrane extrusion, physicochemical characterisation, light- and X-ray-triggered cargo release assessment, in vitro gene knockout in human cells, and in vivo validation using a quantitative zebrafish visual reporter system and a mouse xenograft tumour model. Representative results demonstrate knockout of up to approximately 326 slow-muscle fibres per zebrafish embryo via light activation and significant tumour growth suppression via X-ray-triggered doxorubicin release.The clinical precedent for 689-690 nm verteporfin activation in the eye motivates evaluation of this platform for ophthalmic delivery, although retinal biodistribution, pharmacokinetics, and large-animal safety remain to be established. These methods provide an experimental approach with translational potential for externally controlled therapeutic cargo release."

Although stable transformation in maize is no longer a major obstacle, there remains a need for accessible and efficient methods for academic laboratories. Here, we present the GGB\u00a0system, a rapid and efficient approach optimized for immature embryo transformation in B104 and other maize lines. This system combines two distinct morphogenetic regulators, the wheat GRF4-GIF1 chimera and the maize BABY BOOM (BBM) transcription factor (hence the name \"GGB\") with a modified QuickCorn protocol, enabling regeneration of transformed maize plantlets in c. 2 months with an efficiency 7-fold higher than when compared to either morphogenic factor used in isolation. Expression of both regulators did not significantly affect development, eliminating the need to excise them after regeneration. However, transmission of the transgenic GGB construct through pollen was significantly reduced, potentially aiding transgenic line containment. We show that the GGB system is adaptable for CRISPR-Cas9 editing and reporter line generation. Furthermore, stable GGB transformants exhibited high leaf regeneration capacity via somatic embryogenesis. RNA-seq time-course profiling of GGB leaf cultures identified additional factors that could promote regeneration and led to the discovery of asparagine and trehalose as additional media components that significantly enhanced leaf regeneration."

"abstract_text": "ID: 42594811\nTitle: Pcgf5 controls the exit from totipotency in mouse embryonic stem cells.\nAbstract: Mouse embryonic stem cell (ESC) cultures contain a rare subpopulation of two-cell-like cells (2CLCs) that transiently reactivate a two-cell embryo-like transcriptional program characteristic of zygotic genome activation (ZGA), including the endogenous retrovirus MERVL and Zscan4, and thereby regain a totipotent-like state. Polycomb repressive complex 1 (PRC1)-mediated H2AK119ub1 has been implicated in restraining entry into the 2C-like state through Pcgf6, yet the factors governing exit from this state and loss of totipotency remain poorly defined. Here, we show that among the six Pcgf paralogs, Pcgf5, which is most prominently upregulated in 2CLCs and forms an MERVL-driven chimeric transcript (Pcgf5MT2C_Mm) during ZGA in 2-cell embryos, controls exit from the 2C-like state in mouse ESCs. Using a reporter ESC line carrying MERVL-tdTomato and Zscan4c-EGFP (MtZG), we manipulated Pcgf5 dosage bidirectionally. Doxycycline (Dox)-inducible overexpression (OE) of Pcgf5 reduced the double-positive (DP) 2C-like population. Conversely, CRISPR-mediated knockout (KO) of Pcgf5 by targeting a common exon shared by all Pcgf5 variants (hereafter, total Pcgf5) increased the DP population. Time-lapse imaging directly confirmed that these changes reflected genuine differences in duration of the 2C-like state: OE shortened, whereas KO prolonged, the time cells spent in this state. These findings reveal that a Polycomb group factor controls not only entry into but also exit from the 2C-like state."

Recently, the Ministry of Health in Saudi Arabia approved CRISPR-Cas9 for treating Sickle Cell Disease and beta thalassemia. This study aims to assess the Taif population's opinion on gene editing and their knowledge of genetic modification. In this cross-sectional study, a questionnaire was distributed online from March 2, 2024, to June 15, 2024, to 747 residents of Taif City aged 18 and older. Among the respondents, 14.7% reported that they or their family members suffer from a hereditary disease, and 65.7% either work or study in the healthcare field or have a family member involved in healthcare. Additionally, 50.7% had previously heard of genetic modification. Marital status, number of children, and education level did not significantly influence opinions on genetic editing, whereas affiliation with the healthcare field was significantly associated with greater acceptance\u00a0(p\u2009=\u20090.023), while a family history of hereditary disease showed a trend toward significance (p\u2009=\u20090.055). Public opinion strongly supports using genetic editing to treat life-threatening diseases in adults and embryos (63.2% and 73.6%, respectively). However, opinions are more divided on non-disease traits. Many respondents expressed interest in enhancing intelligence (73.8%) and strength (75.8%), as well as altering height (67.8%) and hair color (60.7%). While support was strong for therapeutic use, opinions were divided on enhancement, reflecting ethical tension despite high interest in modifying non-disease traits. Notably, 50.7% believed that using genetic editing for non-medical purposes crosses ethical boundaries and exceeds nature's limits. Awareness of gene-editing techniques was not significantly associated with acceptance (p\u2009=\u20090.108). In conclusion, public acceptance of gene editing in Taif is high, particularly among healthcare-affiliated individuals. Increasing public awareness remains essential to bridge ethical concerns and support informed engagement."

Current literature confirms the feasibility of CRISPR correction in hematological progenitors and the specification of primordial germ cell-like cells (hPGCLCs) from hiPSCs. However, the translation of these combined technologies into a multi-generational curative strategy for human sickle cell disease remains speculative, constrained by bioethical regulations and the technical requirement for further validation of long-term germline maturation and safety.\n\n### [INTRODUCTION & JUSTIFICATION]\nGene therapy for \u03b2-haemoglobinopathies is based mainly on two strategies: gene addition and gene editing. A technological landmark was achieved when the Food and Drug Administration (FDA) approved the first CRISPR-based gene therapy (exa-cel) to edit erythroid specific enhancer region of BCL11A in hematopoietic stem cells. While this current standard of care provides durable remission for somatic patients, it does not address the hereditary transmission of the HBB mutation. The integration of iPSC technologies suggests an avenue for future germline-level interventions. As noted, one of the first embryonic lineages to be specified in the human embryo is the germ cell lineage, marked by the induction of the primordial germ cells (PGCs). Recent advancements have led to the development of defined protocols that mimic early embryonic development and allow the specification of transcriptomically and epigenetically validated human primordial germ cell-like cells (hPGCLCs). This provides a foundational mechanism for potentially generating germlines. Furthermore, researchers have demonstrated that these results establish a scalable strategy for generating fetal granulosa-like supporting cells from hiPSCs and provide an effective and multi-generational safety framework for oocyte-contact IVM interventions. Although advancements in scientific research, especially gene editing and in-vitro gametogenesis (IVG), are not yet fully applicable, their potential future use appears to pose significant bioethical questions. The gap remains between current somatic gene editing, which is clinically validated for SCD, and the prospect of germline replacement, which lacks clinical authorization and human-validation data.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Current curative gene therapies for SCD (e.g., exa-cel) function through hematopoietic stem cell editing, not germline alteration.\n* CRISPR-mediated editing has been successfully applied to produce humanized DMD mouse models with clinical sequence specificity.\n* The use of ovarian support cells (OSCs) derived from hiPSCs has been shown to improve in vitro maturation outcomes, providing a potential helper-cell platform for gametogenesis.\n* Studies have successfully utilized CRISPR to ablate genes in chicken PGCs, demonstrating that germline-restricted suicide-gene cassettes can generate sterile surrogate hosts.\n* The \"14-day rule\" and other regulatory frameworks significantly limit the current translation of embryological research into clinical reproductive medicine.\n* Synthesis errors in ssODNs are a source of untoward variation in HDR-mediated gene editing, emphasizing the need for rigorous quality control beyond current standards.\n* Porcine expanded potential stem cells (pEPSCs) represent a versatile platform for multiplex genome editing, showing that stem cells can maintain genetic stability through multiple edits.\n* Mechanistic links exist between APP dosage and Notch signaling in iPSC-derived neural models, highlighting that gene dosage effects must be considered alongside mutation correction.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Conventional treatments, such as blood transfusions, iron chelation, fetal haemoglobin induction, and allogeneic haematopoietic stem cell transplantation, have improved outcomes but remain limited by treatment-related toxicity, donor availability, and incomplete curative potential. Methods: A narrative literature review was conducted using PubMed up to 2025. Search terms included \"sickle cell disease,\" \"sickle cell anemia,\" \"\u03b2-thalassemia,\" \"transfusion-dependent beta-thalassemia,\" \"gene therapy,\" \"gene addition,\" \"gene editing,\" \"CRISPR-Cas9,\" \"lentiviral vector,\" \"children,\" \"paediatric,\" and \"pediatric.\" Relevant clinical trials, reviews, consensus statements, and guidelines were selected and qualitatively analysed. Results: Gene therapy for \u03b2-haemoglobinopathies is based mainly on two strategies: gene addition and gene editing. Gene addition uses lentiviral vectors to introduce functional or modified \u03b2-globin genes into autologous haematopoietic stem cells, whereas gene editing targets regulatory pathways, particularly BCL11A, to reactivate fetal haemoglobin synthesis or correct disease-causing mutations. Clinical studies have shown encouraging outcomes, including transfusion independence in many patients with \u03b2-thalassaemia and marked reduction or elimination of vaso-occlusive crises in sickle cell disease. Paediatric and adolescent data are increasingly promising, although still limited. Conclusions: Gene therapy is reshaping the treatment landscape of \u03b2-haemoglobinopathies by offering a personalised and potentially curative approach. However, long-term safety, conditioning toxicity, fertility preservation, accessibility, costs, and implementation in high-prevalence regions remain critical challenges. Further studies are needed to optimise patient selection and expand equitable access."

From the groundbreaking research, the ultimate battle of the prizes and patents to a number of books, the science of CRISPR continues to be significant in the biomedical field. For many decades now, the emergence of synthetic biology as an intervention to correct diseases has become the foundation of biomedical research. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based genetic editing has become a common place for routine investigation of scientific hypotheses in pre-clinical settings. More recently, CRISPR-based diagnostic testing kits for SARS-CoV-2 have showcased a translational output. Furthermore, a technological landmark was achieved when the Food and Drug Administration (FDA) approved the first CRISPR-based gene therapy (exa-cel) to edit erythroid specific enhancer region of BCL11A in hematopoietic stem cells, introduced in patients suffering from sickle cell anemia to achieve durable remission. In this review, we provide a snapshot into the most important milestones along the journey of CRISPR from its discovery in bacteria to its usage in precision medicine. The intervention of machine learning tools has now intertwined complex biology with high-throughput scalable outputs. Given the vast amount of information on CRISPR, we try to pin down key take-home messages for scientists as well as non-scientist readers. This review article attempts to understand why and how CRISPR remains significant and seamlessly integrates in the emerging era of new technologies."

Ex vivo CRISPR-Cas9 editing of autologous CD34-positive hematopoietic stem and progenitor cells to reactivate fetal hemoglobin has produced durable freedom from severe vaso-occlusive crises in SCD and sustained transfusion independence in TDT. This approach offers a donor-independent alternative to allogeneic hematopoietic stem-cell transplantation without graft rejection or graft-versus-host disease. Hemoglobinopathies, therefore, provide the first clinically validated delivery model for CRISPR therapeutics. Successful implementation, however, requires more than editing efficacy. It depends on structured referral, candidacy assessment, organ function review, mobilization and collection, centralized manufacturing, pharmacokinetic-guided myeloablative conditioning, transplant-level supportive care, fertility preservation, psychosocial support, and prolonged surveillance coordinated among primary hematologists and cellular therapy programs. Key barriers include stem cell collection, conditioning-related toxicity, cost, reimbursement friction, and persistent inequities in access. Long-term follow-up and registry participation are necessary to evaluate outcomes beyond pain crises, identify late toxic effects, and compare real-world effectiveness across gene editing, gene addition, and allogeneic transplantation. In oncology, CRISPR-based therapy remains investigational, with early clinical feasibility demonstrated in relapsed or refractory B-cell malignancies, T-cell malignancies, AML, multiple myeloma, and selected solid tumors. For hematologists, oncologists, and transplant and cellular therapy programs, the central challenge is to integrate CRISPR into practice with the rigor required for any high-risk curative therapy: careful patient selection, disciplined delivery, and long-term accountability."

"abstract_text": "ID: 41416641\nTitle: The road to restore male fertility using in vitro-derived germ cells.\nAbstract: Human-induced pluripotent stem cells (hiPSCs) offer immense potential in reproductive medicine, particularly for males who lack germ cells and cannot achieve biological parenthood through conventional ARTs. Early efforts to derive human germ cells from stem cells were hindered by low efficiency, subpar characterization, and the lack of standardized differentiation approaches. However, recent advancements have led to the development of defined protocols that mimic early embryonic development and allow the specification of transcriptomically and epigenetically validated human primordial germ cell-like cells (hPGCLCs). Current research focuses on maturing hPGCLCs in vitro, particularly within 3D culture systems that resemble their physiological microenvironment, with the aim of producing transplantable hiPSC-derived spermatogonial stem cells (SSCs) or differentiating them to sperm. At the same time, researchers are also testing whether hiPSCs generated from infertile patients can resume germline differentiation. This narrative review aimed to summarize the key efforts and remaining challenges in differentiating male germ cells from human pluripotent stem cells (hPSCs), with a particular focus on defined and validated protocols for hPGCLC specification. In parallel, we addressed key safety and ethical considerations that must be accounted for the development of clinical applications. A deeper understanding of the approaching therapeutic use of hiPSCs in reproductive medicine is essential for developing novel regenerative fertility strategies. PubMed, Scopus, and Web of Science were searched for studies attempting germ cell differentiation from hPSCs using relevant keywords ('stem cells', 'human pluripotent stem cells', 'human embryonic stem cells', 'human induced pluripotent stem cells', 'somatic cell reprogramming', 'infertility', 'germline', 'spermatogenesis', 'germ cells', and 'primordial germ cells'). No time period restriction was established. Studies with an exclusive focus on female germline differentiation were excluded. To maintain a human-focused perspective, only key animal studies are presented. The literature reveals a clear segregation among protocols for deriving germ cells from hPSCs, particularly between earlier studies lacking standardized differentiation conditions and characterization, and the most recent, defined protocols having transcriptomic and epigenetic validation against in vivo hPGCs. Moreover, during the last decade, the field has seen remarkable progress, with multiple efforts aimed at maturing hPGCLCs, closely recapitulating late male embryonic germline development. Additionally, hiPSCs derived from male patients at risk of infertility, particularly those without underlying genetic syndromes, generally retain the capacity for early germline commitment. While attempts at maturating patient germ cells beyond the hPGCLC state remain limited, the rapid pace of discovery and refinement in recent years suggests that further breakthroughs, including clinically applicable fertility restoration strategies, are likely to be achieved in the near future. The ability to generate hiPSCs from infertile patients and to specify them into hPGCLCs supports the feasibility of obtaining hiPSC-derived SSCs for future therapeutic use. These advances raise important ethical, regulatory, and societal questions that must be actively discussed among researchers, clinicians, policymakers, and the general public to ensure responsible and equitable access to these technologies.

One of the first embryonic lineages to be specified in the human embryo is the germ cell lineage, marked by the induction of the primordial germ cells (PGCs). The PGCs are the sole founder population of the gametes later in life, and their specification is a critical first step towards the organism's fertility. Here, a robust protocol for generating PGC-like cells (PGCLCs) from human induced pluripotent stem cells (hiPSCs) is described, starting with the initial evaluation of the pluripotent state and cellular characteristics of the hiPSCs to ensure effective PGCLC differentiation. For this, the effects of different cell densities, plate coatings, and hiPSCs used for PGCLC differentiation are discussed. Finally, a workflow for characterization and quantification of hPGCLCs, using immunofluorescence and flow cytometry, is provided. The differentiation protocol focuses on conditions that are easy to establish and test in most laboratories and can be adjusted as necessary. Moreover, this protocol is fast, allowing determination of whether hiPSCs are suitable for PGCLC differentiation. The protocol aims to promote consistency and compatibility in hPGCLC outcomes across different hiPSC lines and culture platforms, ensuring robust yields that support reliable characterization and further optimization of downstream differentiation steps toward successful in vitro gametogenesis in humans."

We generated an endogenous FOXL2-P2A-tdTomato reporter human induced pluripotent stem cell (hiPSC) line using CRISPR/Cas9 knock-in and reporter-guided transcription factor (TF) programming to produce fetal granulosa-like cells (FGLCs). A flow cytometric TF screen identified TCF21, WT1-KTS, and NR1H4 as the strongest FOXL2 inducers, and combinatorial optimization showed that removing TOX3/ETV5 and adding NR2F2 substantially increased the FOXL2-positive fraction. Bulk RNA-seq, principal component analysis, and TF activity inference positioned the induced cells close to early-gestational human fetal granulosa cell profiles. In a mouse IVM, in vitro fertilization (IVF), blastocyst culture, and embryo transfer pipeline, FGLC supplementation did not change nuclear maturation rates but improved downstream development, most clearly increasing offspring production from cumulus-oocyte complexes. A comprehensive safety assessment of F0 offspring derived from FGLC-treated oocytes revealed a normal sex ratio, postnatal growth, gross anatomy, gonadal histology, and modified SHIRPA neurobehavioral profiles. Next-generation natural mating and germ cell assays demonstrated preserved fertility, normal IVF outcomes, and normal sperm parameters in the F1 generation. These results establish a scalable strategy for generating fetal granulosa-like supporting cells from hiPSCs and provide an effective and multi-generational safety framework for oocyte-contact IVM interventions."

LVVs are used to deliver and induce the stable expression of transgenes through genome integration. Current clinical LVV delivery systems do not include HIV-1 major accessory genes; however, critical structural and non-structural HIV-1 proteins are encoded by the 4-plasmid combination that composes the 3rd generation LVV transduction systems. LVVs use HIV-1-like mechanisms for viral genome integration and both transgene delivery and expression. LVVs rely on host cell machinery to transcribe and translate transgenes for either knocking down disease-causing genes and/or supplying functional genes in a targeted disease. LVVs integrate into host intronic and intergenic regions due to genomic accessibility, but there are no known biases toward specific target integration motifs. Investigation of LVV integration has uncovered the generation of chimeric LVV-host transcripts and altered host transcript splicing patterns. Several Food and Drug Administration (FDA)-approved LVV-derived therapies are used for treating diseases ranging from beta thalassemia to sickle cell anemia. An increasingly popular application of LVV is in the generation of chimeric antigen receptor (CAR) T cell therapies, which change and enhance T cell antigen specificity and effector function in liquid cancers. In November 2023, all CAR T cell therapies were placed under FDA investigation due to higher-than-expected rates of malignant transformation, hospitalization, and death in treated individuals. LVV integrations driving oncogene expression could be a cause for malignancy development. Current methods for resolving LVV integration patterns are technically limited by the sequencing approach applied allowing for only limited characterization of LVV integration profiles and altered host gene regulation. A comprehensive understanding of LVV integration and its consequences is necessary for understanding how these events influence host cell gene regulation and splicing, possibly identifying tunable variables for enhanced positive clinical outcomes. Here, we review the development of LVV systems, what is known about LVV integration patterns, technologies used to characterize patterns of LVV integration, and what is understood about the subsequent impact on host cell gene regulation and its potential linkage to patient malignancies."

Despite early promise, clinical adoption of IVM has been limited due to lower embryo developmental competence and live birth rates compared to IVF. However, recent advances in the understanding of oocyte physiology, including cumulus-oocyte communication, the regulatory roles of cAMP/cGMP signaling pathways, and endocrine modulation of meiotic resumption, have reignited interest in optimizing IVM protocols. Innovations such as biphasic Capacitation (CAPA) IVM systems and the use of ovarian somatic support cells (OSCs) derived from induced pluripotent stem cells (iPSCs) aim to replicate the dynamic follicular environment more accurately and enhance oocyte competence. Clinical studies suggest that, while IVM still results in modestly lower cumulative live birth rates compared to conventional IVF, it offers significant advantages for selected patient populations, particularly women with polycystic ovary syndrome (PCOS), high ovarian reserve, or those requiring fertility preservation. Importantly, current evidence supports the genetic and epigenetic safety of IVM-derived offspring. As technical refinements continue and professional education expands, IVM is poised to fulfill its potential as a safer, less invasive, and more accessible alternative within the landscape of assisted reproductive technologies."

On one side, the 14-day rule has faced criticism from embryo researchers advocating for its extension. On the other side, the increasing number of cryopreserved embryos worldwide has raised practical and ethical concerns about their fate. While advancements in scientific research, especially gene editing and in-vitro gametogenesis (IVG), are not yet fully applicable, their potential future use appears to pose significant bioethical questions. In this review, we examine the evolving bioethics of embryo research, focusing on the 14-day rule, the challenges surrounding surplus cryopreserved embryos, and the future dilemmas posed by CRISPR-based gene editing, IVG, and preimplantation genetic testing for polygenic risk (PGT-P). We also highlight the critical role of multidisciplinary, patient-centered counseling in ART practice, to foster informed consent, realistic expectations, and psychosocial well-being. Finally, we underscore the need for anticipatory ethical frameworks and open-society engagement that integrate public deliberation with scientific progress to ensure that reproductive innovation proceeds responsibly, preserving both human dignity and social justice."

The model Act is a modular, risk-tiered scheme with consistent standards and tailored red lines. It is designed to accommodate boundary cases, to integrate and build upon the existing remit of the Human Fertilisation and Embryology Authority, and coordinate with other established regulators to retain institutional expertise and avoid unnecessary duplication. The proposal is ambitious and would help give effect to UK Government commitments to safely advance the life sciences in this area. But even if piecemeal amendments are ultimately favored, it clarifies the underlying choices and trade-offs and provides a benchmark against which changes can be tested."

This review synthesizes current advances aimed at enhancing the specificity of CRISPR diagnostics, with particular emphasis on the pivotal role of CRISPR RNA (crRNA) engineering. We detail how structural determinants of crRNA, including spacer length optimization, intentional mismatch design, secondary-structure modulation, chemical modification, strand-displacement gating, and synergistic design frameworks, govern CRISPR-mediated target recognition and define the energetic and kinetic thresholds for accurate cleavage. Key engineering strategies encompassing computational prediction and modeling, high-throughput screening, and hybrid guide architectures are systematically examined for their capacity to elevate single-nucleotide discrimination, stabilize reaction performance, and enable robust multiplexed detection for pathogen profiling and mutation identification. Despite rapid progress, outstanding challenges persist, including interference from complex clinical matrices, lack of unified evaluation standards, and scalability barriers that hinder clinical translation. Addressing these limitations through integrated crRNA design, system-level optimization, and standardized benchmarking will be essential for realizing the promise of CRISPR diagnostics. Ultimately, these advances are poised to support ultrasensitive, highly specific, and portable point-of-care testing, thereby accelerating precision medicine and strengthening infectious disease surveillance and management."

Although ssODN sequence fidelity is critical to the safety and efficacy of editing, standard quality control methods cannot resolve individual nucleotide errors. Methods: We performed deep sequencing of ssODNs from three manufacturers and amplicons from edited hematopoietic stem/progenitor cells. Results: We find that synthesis errors are present in all ssODNs tested at rates that vary more than two-fold among manufacturers, at positions that are dependent on sequence context. These synthesis errors are propagated into the genome by HDR at frequencies proportional to their abundance in the ssODN. In our sickle cell mutation correction protocol, the most prevalent SNEs are predicted to produce benign \u03b2-globin variants, while the less frequent frameshift deletions are predicted to generate \u03b2-thalassemia-like alleles. Conclusions: Current quality control standards are insufficient to detect these errors, and deep sequencing of ssODNs should be incorporated into regulatory submissions for clinical gene editing programs."

Prime editing enables precise genome modification without generating double-strand DNA breaks or requiring donor DNA templates. We established an in vitro prime editing workflow to generate and subsequently correct the mdx5cv mutation in mouse C2C12 myoblasts. Following optimization of engineered prime editing guide RNAs (epegRNAs) and PAM-flexible prime editors, wild-type cells were edited, clonally isolated, and genotyped. Mutation correction was then evaluated using optimized epegRNA designs. Two rounds of prime editing introduced the mdx5cv mutation into approximately 20% of alleles in C2C12 cells creating the mdx5cv C2C12 cell line. Clonal isolation yielded five homozygous mutant clones among 59 expanded colonies. Optimization studies identified an epegRNA containing a 16 nucleotide reverse transcription template and a 10 nucleotide primer binding site (RTT16/PBS10) as the most efficient design. Correction of the pathogenic allele reached approximately 26%, whereas longer PBS lengths reduced editing efficiency. In silico off-target analysis using Cas-OFFinder identified no candidate genomic loci with fewer than three mismatches for the spacer sequences used in either mutation generation or correction, suggesting a favorable predicted specificity profile. Corrected mdx5cv C2C12 myoblasts retained their capacity to differentiate into multinucleated myotubes. Representative Western blot analysis detected dystrophin protein expression in differentiated corrected mdx5cv myotubes, consistent with successful correction of the pathogenic mutation. These findings establish a robust prime editing platform for both the generation and correction of the mdx5cv mutation and provide proof of concept that precise correction of the pathogenic mutation is associated with restoration of dystrophin expression following myogenic differentiation."

These K27M mutations shape intratumoral myeloid cell composition in DMG. In H3.1K27M DMGs, genetic ablation of monocyte recruitment reshapes the tumor microenvironment (TME) by reducing monocyte-derived macrophages (MDMs) and increasing microglia and neutrophil presence, with overall survival remaining unchanged, indicating compensatory myeloid remodeling is occurring. Here, by using CRISPR/Cas9-based genome editing, we generated a mouse model deficient for CCR1/CCR2/CCR3/CCR5 (\u03941235). Using this strain, we effectively abolished monocyte and MDM infiltration and reversed compensatory recruitment of CCR1+ neutrophils. Abolishing MDMs in tumors skewed remaining neutrophils and microglia toward a homeostatic state, reduced expression of immune checkpoint molecules on T cells, and extended the survival of H3.1K27M DMG-bearing mice. In contrast, H3.3K27M DMG showed independence from MDM recruitment, suggesting reliance on other TME-driven signaling. Last, H3.1K27M DMGs exhibited reduced microglia presence and a dose-dependent increase in MDM infiltration postirradiation. MDM depletion did not further enhance radiation efficacy, potentially due to compensatory recruitment of classical neutrophils. Collectively, these data reveal histone mutation-specific myeloid dependencies in DMG, highlighting MDM-independent mechanisms in H3.3K27M tumors and MDM-dependent pathways in H3.1K27M tumors."

Placental insufficiency is associated with adverse pregnancy outcomes, including fetal growth restriction, preeclampsia, and pregnancy loss. Moreover, emerging evidence suggests that placental defects are associated with long-term health challenges that manifest well into adulthood; yet the etiologies of such diseases are largely unknown. Defining the mechanistic basis for placental deficiencies, therefore, has important implications for improving both reproductive health and the lifelong well-being of affected children. Down syndrome is characterized by placental defects of unknown mechanistic origin, and notably, individuals with Down syndrome are at increased risk of developing diseases commonly associated with placental insufficiency later in life. Using induced pluripotent stem cells from Down syndrome patients, we found that stem cell-based embryo models (i.e., blastoids) and directed differentiation systems recapitulate trophoblast cell fate defects observed in placentas affected by Down syndrome. Furthermore, we demonstrate that attenuated estrogen signaling contributes to placental syncytialization defects and identify NRIP1, a transcriptional corepressor of estrogen receptor that is located on chromosome 21, as a key driver of trophoblast cell fate defects. Increased gene dosage of NRIP1 in an otherwise diploid cell line phenocopies cell fate defects observed in trophoblasts affected by Down syndrome.

In our previous work, TNFRSF13B exon 2 variants were recurrently identified in chronic active Epstein-Barr virus disease (CAEBV). Here we aim to reveal the roles of TNFRSF13B variants in CAEBV, and investigate the feasibility of targeting TNFRSF13B/TACI as a new approach to control EBV infection. The lymphoblastoid cell lines (LCL) models carrying homozygous TNFRSF13B exon 2 frameshift mutations were constructed using CRISPR/Cas9. Immunological assays, transcriptomic analysis, and gene silencing experiments were performed on LCL models to measure the effect of TNFRSF13B exon 2 variants and explore the underlying mechanisms. TACI ligands and a TLR9 agonist were applied to modulate TACI signaling and EBV activities. Frameshift mutations in exon 2 of TNFRSF13B significantly up-regulated the short isoforms of TACI (TACI-S) at the expense of its long isoforms (TACI-L) in LCLs. The up-regulated TACI-S induced more intense activation of NF-\u03baB, MAPK, and Rho signaling pathways, leading to the switch of EBV activities to lytic reactivation. The subsequent increased viral load and viral IL-10 provide a rational for the susceptibility of variant carriers to CAEBV. The BAFF trimer, an indirect TACI-signaling inhibitor, also significantly suppressed the EBV lytic program. Gene silencing experiments indicated that XBP-1 might be involved in the TACI-mediated regulation of EBV lytic activities in EBV-immortalized B cells. This study underscores the impact of TNFRSF13B variants on EBV infection and host immune responses, offering insights into CAEBV pathogenesis and potential therapeutic strategies."

Although gap larvae exhibit normal external morphology, gap mutants exhibit severe defects in adult organs, suggesting that the gap gene is required for the development of imaginal discs and the primordia of adult organs. Genetic analysis of the gap mutation provides an opportunity to understand the molecular mechanisms underlying the development of adult organs. In this study, we performed RNA-seq analysis of ovaries from gap mutants. De novo assembly of RNA-seq reads identified the insertion of a retrotransposon in the gene encoding the Bombyx ortholog of protein-cysteine N-palmitoyltransferase (Rasp), which is required for Hedgehog signaling in Drosophila. PCR and subsequent sequencing analyses revealed that an LTR transposon is inserted into exon 1 of the BmRasp gene.

However, the path to this milestone reveals a pattern of MSCs failing in late-phase clinical trials. Multiple sources of heterogeneity may explain these results, including variability in donor and recipient biology, product manufacturing and characterization, and trial design. For example, certain subsets of acute GVHD patients, particularly those with inflammatory/immune activation, may derive the greatest clinical benefit from MSCs. Trials failing to stratify for this patient-level heterogeneity risk failure while obscuring signals of efficacy in responsive subgroups. Improving trial design considering heterogeneity requires leveraging advances in MSC manufacturing and refining clinical trial methodologies.

Through endothelial co-culture approaches, vascularised and metabolically zonated liver organoids have been successfully generated, achieving endothelial coverage exceeding 85%. Prime editing enables precise correction of pathogenic mutations in patient-derived organoids, with no off-target effects detected at the genome-wide level. In disease modelling, iPSC-derived liver organoids faithfully recapitulate the pathological progression of metabolic dysfunction-associated steatotic liver disease (MASLD) and verify the lipid-lowering efficacy of semaglutide. Macrophage-integrated organoid models support the full life cycles of HEV, SARS-CoV-2 and dengue virus, providing new tools for antiviral drug screening.

Nevertheless, insufficient hepatocyte functional maturity, difficulties in constructing vascular networks, and the lack of standardised culture protocols remain major obstacles to clinical translation.

The approach relies on the stable integration of transgenes encoding the transcription factors ASCL1 and DLX2 into the safe-harbor adeno-associated virus integration site 1 (AAVS1.) locus via CRISPR/Cas9-mediated knock-in. This targeted integration avoids the transgene silencing often observed with random lentiviral integration. The protocol covers the maintenance of hiPSCs, the nucleofection process for transgene integration, puromycin selection to enrich successfully engineered cells, and the step-by-step differentiation procedure. Upon induction with doxycycline, the engineered hiPSCs rapidly exit the cell cycle, acquire neuronal morphology, and express GABAergic lineage markers within 21 days. Key steps include neuro-induction and subsequent maturation using specific growth factors, as well as potential approaches to improve cellular adhesion during maturation. This standardized method yields enriched populations of induced neurons expressing GABAergic lineage markers, providing a valuable tool for neuroscience research and cellular modeling."

Different models, based on cultured cardiomyocytes, were proposed for the last 30\u2009years to explain the sequence of events.

This review will discuss the general principles of myofibril assembly in the heart and cover new findings on myofibril maintenance and turnover."

Here, we establish the first comprehensive human mechanistic model of PPP1R9A haploinsufficiency using an isogenic CRISPR/Cas9-engineered iPSC system differentiated into cortical neurons to define dosage-dependent functional consequences. PPP1R9A+/- neurons exhibited pronounced hyperspinogenesis and increased neuritic complexity, indicative of aberrant structural maturation; however, whole-cell patch-clamp recordings revealed impaired intrinsic excitability, including reduced action potential firing, altered waveform properties, and defective axo-somatic coupling, uncovering a striking dissociation between neuronal morphology and function. Long-read single-cell transcriptomics and quantitative proteomics identified coordinated downregulation of ion channel and synaptic transmission pathways, including genes essential for sodium channel function and glutamatergic signaling, together with disruption of synaptic vesicle cycling, axon guidance, and neurodevelopmental programs. Pseudotime trajectory analysis further demonstrated delayed neuronal differentiation, with mutant neurons accumulating at intermediate developmental states rather than acquiring mature cortical identities. Importantly, molecular rescue experiments confirmed causality, as restoration of full-length PPP1R9A expression robustly normalized transcriptional and synaptic signaling programs, whereas allele-specific antisense oligonucleotide-mediated suppression of the mutant transcript achieved only partial rescue. Taken together, these findings establish PPP1R9A haploinsufficiency as a driver of impaired molecular, electrophysiological, and developmental maturation in human cortical neurons, providing a human-specific mechanistic framework linking reduced Neurabin I dosage to neurodevelopmental and psychiatric disease risk."

Although stem cell-based therapies have shown promise for vascular regeneration, their clinical translation has been limited by poor survival, insufficient engraftment, functional heterogeneity, and immune rejection. Recent advances in genome-editing technologies, including CRISPR/Cas9, base editing, and prime editing, have provided powerful tools for overcoming these limitations through precise genetic modification of stem cells. Gene editing can enhance angiogenic potential, improve resistance to ischemic stress, augment paracrine activity, promote endothelial maturation, and reduce immunogenicity. In this review, we outline the current genome-editing toolbox and its application to stem cell engineering for vascular regeneration in ischemic disease. We also examine emerging therapeutic concepts, universal donor cell platforms, and key issues in safety and ethics, with a focus on translational pathways. Taken together, advances at the interface of genome editing and stem cell biology are likely to accelerate the development of regenerative therapies that deliver more durable vascular repair in ischemic vascular disease."

In this study, the BCH gene in Nicotiana tabacum was targeted using CRISPR/Cas9 genome editing to redirect metabolic flux toward \u03b2-carotene accumulation and evaluate its effects on heat tolerance. Following Agrobacterium-mediated transformation with a BCH-specific gRNA, three mutant plants were obtained; two carrying frameshift mutations (P1 and P3) and one with mis-sense mutations (P2). A significant increase in chlorophyll contents was observed in the edited lines compared with wild-type plants. Interestingly, the frameshift mutants exhibited substantial increase in total chlorophyll (71% and 31% in P3 and P1 respectively) as compared to mis-sense mutant P2 (18%). Further, biochemical profiling using HPLC showed that the edited plants accumulated 3.74-fold increase in \u03b2-carotene than wild-type plants. Under heat stress (42\u202f\u00b0C for 96\u202fh), the edited plants exhibited enhanced thermotolerance by remaining greener and delayed wilting, whereas wild-type plants developed necrosis rapidly under heat stress. This enhanced thermotolerance might has resulted from the increased expression of \u03b5-cyclase (an upstream key enzyme in \u03b2-carotene biosynthesis) as revealed by expression profiling of edited plants. In contrast, the expression of downstream \u03b2-cryptoxanthin and zeaxanthin biosynthetic genes was reduced, which seems consistent with mutation of BCH. DAB staining further confirmed reduced ROS accumulation in edited plants as compare to wild type supporting the protective role of \u03b2-carotene. In summary, the downregulation of BCH in N. tabacum boosted \u03b2-carotene levels and chlorophyll retention, enhancing heat stress tolerance. These findings demonstrate the potential of targeting carotenoid biosynthesis to improve crop resilience."

It may act in a very disparate manner; ranging between slow growing, well differentiated tumours to an aggressive anaplastic subtype. Initial treatment with standard therapy, surgery, radioactive iodine, the thyroid-stimulating hormone inhibition and in some cases, chemotherapy or external-beam radiations are effective with the differentiated cancers at the early stages. Nevertheless, there is no choice with tumours, which become unresponsive to iodine, metastasized, or un- differentiated. Recent developments in molecular oncology have elucidated the genetic alterations that contribute to thyroid cancer, in particular, the MAPK and PI3K/AKT/mTOR pathways, and BRAF, RAS, RET, and TERT promoter mutations. The current review summarizes the changing therapeutic environment of thyroid cancer that includes established targeted medicines and novel developments. These are immune checkpoint inhibitors, redifferentiation based on reinstatement of iodine uptake, selective RET and BRAF/MEK, RNA-based therapeutics, CRISPR gene editing, oncolytic virotherapy, peptide receptor radionuclide therapy, alpha-particle radiotherapy, and nanotechnology-based drug delivery systems. A combination regimen involving molecular targeting and immunotherapy or radioactive iodine is also improving the disease in advanced disease. Collectively, the advances are an indication of a transition to the personalized, mechanism-driven treatment strategies that would prolong the survivability of patients with advanced thyroid cancer, conquer resistance, and reduce systemic toxicity."

A novel body shape mutant, stony^sunken (st^sk), that exhibits a sunken intersegmental membrane was isolated from the wild type of st^sk (WT-n08). Investigation indicated that the mutation had no significant effect on its growth and development. To elucidate the molecular mechanism underlying this body shape mutant, genetic analysis, positional cloning, and the CRISPR/Cas9 gene editing system were performed. Genetic analysis demonstrated that the mutant trait in st^sk is controlled by an autosomal recessive gene and follows Mendelian inheritance. Positional cloning showed that a putative cuticular protein gene, BmorCPR2 on chromosome 8, was the candidate gene. Sequencing analysis revealed partial deletion of BmorCPR2 exon 2 and intron 2 sequences occurred and subsequently resulted in the premature termination of gene expression. Knock-out of BmorCPR2 using the CRISPR/Cas9 gene editing system led to the sunken intersegmental membrane phenotype. These findings highlight the essential role of BmorCPR2 in silkworm cuticular formation, providing a foundation for further research on cuticular protein function."

Here we study APP specifically in the context of Trisomy 21. In an effort to reduce APP dosage in trisomy 21 iPSCs, we generated trisomic isogenic lines which vary in APP dosage, including a full APP knock-out line, as well as lines carrying mutations of the APP extracellular domain. We used a panel of these lines to study potential impacts of APP dosage or structure on two distinct steps of neurogenesis in trisomic cells: 1) terminal differentiation of human neuro-progenitor cells (NPC) to post-mitotic neurons and 2) neuron structure as reflected in neurite outgrowth. Complete loss of APP causes marked defects in each of these two distinct steps, reducing both the terminal differentiation of NPCs to neurons, and proper neurite development for extended neuron structure. Hence, APP is necessary for both aspects of normal neurogenesis. Further analyses of the null and other mutant lines indicate that APP likely impacts these two distinct steps by two different mechanisms. Collective results suggest that the reduced terminal differentiation of NPCs reflects an effect of APP dosage, whereas the defects in neurite extension are due to structural mutation of the APP extracellular domain. Absence of APP or reduced (monosomic) APP dosage prolonged the cycling of trisomic NPCs, which is known to be regulated by Notch signaling. APP and Notch are the main targets of gamma-secretase cleavage, hence we hypothesized that APP dosage may impact neurogenesis indirectly, potentially via effects on Notch signaling. To test this, we treated NPCs with Compound E which inhibits gamma-secretase (and Notch signaling); results show this restored levels of neurogenesis in APP depleted lines, supporting an indirect effect of APP dosage . In contrast, results indicate that disruption of APP extracellular domain integrity impacts neurite extension via a more direct role of APP in neuron structural maturation. This study describes a resource of well-characterized APP mutant isogenic DS iPSC lines, implicates a dynamic interplay between APP dosage and Notch signaling, and raises new questions about the impact of APP dosage in orchestrating neural progenitor fate decisions during human brain development, specifically in the context of trisomy 21."

Taking advantage of the single-guide RNA (sgRNA) and protospacer adjacent motif (PAM) sequence (3'-NGG) specificity of the Cas9 protein in the CRISPR/Cas9 (Clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9) system and codon degeneracy, the authors design a repair template that incorporates the desired point mutation while excluding the PAM sequence disrupted by a synonymous substitution, thereby preventing re-cleavage by CRISPR/Cas9. This method employs two available plasmids, pCasKP-apr and pSGKP-spe, offering straightforward operation and high screening specificity. As a result, the approach enables efficient generation of genetically defined mutant strains of Klebsiella pneumoniae (K. pneumoniae) and is readily adaptable to routine laboratory settings.

However, traditional microinjection methods for RNP delivery in insect embryos are labor-intensive, technically demanding, and often reduce embryo viability, especially in species with fragile, microscopic embryos. In this study, a novel, non-invasive delivery method for the RNP complex in tiny insect embryos has been optimized. Whitefly, Bemisia tabaci, an invasive insect pest of agricultural importance and vector of plant diseases, was considered as a model organism. A needleless dechorionation-permeabilization method was employed to deliver the RNP complex to the early embryonic stage of B. tabaci embryos. B. tabaci heat shock protein 70 (hsp70) gene, which interacts with the begomovirus coat protein, aiding in its internalization and successful transmission by B. tabaci in a persistent circulative manner, was targeted for knockout. Two sgRNAs were synthesized via in vitro transcription, and the Cas9-sgRNA complexes were validated by in vitro cleavage assays. The localization of the GFP-labelled Cas9-sgRNA complex confirmed successful RNP delivery, as observed through confocal microscopy. A survival rate of 18% of the embryos was recorded post-RNP delivery. Sequencing of treated embryos showed 25- and 28-nucleotide deletions in the hsp70 exon. Synthego ICE analysis revealed up to 84% gene knockout efficiency. This method enables batch processing of embryos, drastically reducing delivery time and associated costs while improving throughput. Hsp70 KO B. tabaci mutants generated in the study are expected to be incompetent begomovirus transmitters, which would help restrict the spread of the virus. Our study overcomes a key bottleneck in CRISPR/Cas delivery to small insect embryos, opening new avenues for rapid, high-throughput, and cost-effective RNP delivery methods in insect embryos. The novel non-invasive methods would be helpful in the deployment of gene editing for sustainable pest control."

Francisella novicida Cas9 (FnCas9) exhibits high intrinsic specificity but is constrained by stringent PAM requirements. Here, we quantitatively examine the energetic and catalytic consequences of PAM-interacting mutations in three engineered variants, en1 (E1369R), en15 (E1603H), and en31 (G1243T/E1369R/E1449H), using a VEGFA3 DNA substrate framework. Microscale thermophoresis and isothermal titration calorimetry reveal that the engineered variants enhance binding affinity toward the canonical NGG PAM relative to wild-type FnCas9, with modest gains in binding free energy. Selected noncanonical PAM substrates, particularly TGA and TAG, also show improved binding by en15 and en31, with en31 displaying the strongest overall binding among the substrates tested. Thermodynamic profiles indicate that enhanced affinity is associated with more favorable enthalpic contributions, consistent with altered interactions at the PAM interface; however, the specific molecular contributions underlying these changes remain to be directly established. Despite improved binding, active-site titration reveals reduced fractions of catalytically competent enzyme in engineered variants, particularly en31, necessitating higher enzyme concentrations to achieve cleavage efficiencies comparable to wild-type. Cleavage assays demonstrate that en31 most effectively couples improved recognition of the tested noncanonical PAM substrates to productive catalysis, enabling robust cleavage of both TGA and TAG substrates while maintaining minimal off-target activity under the conditions examined. Together, these results suggest that PAM-interacting mutations in FnCas9 can alter the energetic coupling between DNA binding and catalytic activation within the VEGFA3 substrate framework tested, highlighting the importance of balancing substrate affinity with conformational activation in the design of high-precision genome-editing nucleases."

MicroRNAs (miRNAs) have emerged as an essential post-transcriptional regulator of host-virus interactions, influencing viral replication, immunological responses and disease progression. This review offers a comprehensive overview of the miRNA-virus axis in RNA virus infections, highlighting the dynamic and context-dependent roles of host miRNAs. We investigate the mechanistic basis of miRNA-mediated regulation, including direct targeting of viral RNA, modulation of host dependency factors, regulation of antiviral signaling pathways, and immune-mediated effects on infection outcomes. We propose a functional categorization of miRNAs that transcends the conventional antiviral-proviral dichotomy, facilitating a more accurate comprehension of their involvement in various infection settings. This review connects mechanistic insights with translational applications by outlining novel treatment techniques, such as miRNA mimics, anti-miRs, RNA interference, and CRISPR-based methodologies. We also propose a therapeutic decision framework that links miRNA functional classification with targeted antiviral interventions. Key challenges including delivery efficiency, tissue specificity, and off-target effects are also discussed, with emphasis on lipid nanoparticles and exosome-based delivery systems. We further highlight the role of systems biology approaches, including multi-omics integration, single-cell and spatial transcriptomics, network analysis, and artificial intelligence, in identifying regulatory miRNA hubs and enabling precision antiviral medicine.

In this study, we established a highly sensitive and specific assay by combining peptide nucleic acid (PNA)-mediated PCR clamping with CRISPR/Cas13a trans-cleavage detection. A PNA probe targeting the wild-type (WT) EGFR T790M allele was designed to suppress WT amplification during PCR, while minimally affecting mutant allele amplification. By combining the target specificity of Cas13a for mutant alleles with the WT-suppression capability of PNA-PCR, we achieved a dual-enrichment effect for mutant detection. When applied to EGFR T790M mutation detection, the assay reached an analytical sensitivity of 0.02%. We established a standard curve for T790M detection using cell-free DNA standards. Clinical validation in 20 plasma samples from lung adenocarcinoma patients demonstrated that the PNA-Cas13a assay achieved a diagnostic sensitivity of 93.3% (95% CI: 68.1%-99.8%) and a specificity of 100% (95% CI: 47.8%-100%), with detection concordance comparable to or improved over ARMS-PCR in this pilot cohort.

We previously identified RNA viruses that infect the nematodes C. elegans and C. briggsae in a species-specific manner. Wild strains of both host species demonstrate ample variation in viral sensitivity. Here we use recombinant inbred lines and pool-sequencing approaches to genetically map a major resistance locus in the C. elegans MY10 strain, narrowing down its position by CRISPR/Cas9 mediated recombination and testing candidates by genome editing. A rare non-synonymous polymorphism in the gtnt-1 gene, encoding a putative glycosyltransferase of the GT92 family, causes resistance to viral infection in MY10. Loss-of-function gtnt-1 alleles conferred host protection only at late developmental stages, highlighting the importance of multigenerational assays capturing the full course of viral infection and transmission. Viral resistance through gtnt-1 mutation occurred repeatedly in C. elegans, with diverse alleles each remaining at low frequency (<1%). Furthermore, leveraging closely related C. briggsae strains differing in viral susceptibility, we find that repeated loss-of-function alleles of the Cbr-gtnt-1 ortholog similarly enhanced resistance and host fitness upon infection. In conclusion, recurrent evolution in two host species of loss-of-function alleles of gtnt-1 orthologs leads to viral resistance. The gtnt-1 gene being conserved between Caenorhabditis species, these repeated inactivation events provide a case of transient ecological adaptation to a pathogen through recurrent mutation of the same gene in two species. The low population frequencies of resistant alleles point to a changing eco-evolutionary context that prevents their spread in populations."

Rhesus induced pluripotent stem cells (RhiPSCs) derived from these monkeys present a unique opportunity for in vitro modeling and comparison with cells derived from MAPT R406W human carriers. Here, we report the development of a reproducible method to generate RhiPSCs compliant with the standards of the International Society for Stem Cell Research (ISSCR) to support in vitro modeling of FTD-MAPT R406W. Our stepwise approach identified efficient methods for fibroblast derivation, fibroblast reprogramming to RhiPSC, and RhiPSC maintenance over continued culture. To derive fibroblasts from MAPT wild type (WT) and R406W monkeys, a combination of manual processing and overnight enzymatic digestion was required to maximize the number of low passage fibroblasts available for reprogramming. Fibroblast reprogramming to RhiPSC using Sendai viral vectors versus oriP/EBNA1 episomal plasmids revealed the latter as most efficient. Electroporation conditions for oriP/EBNA1 reprogramming were optimized to maximize plasmid uptake and cell survival. Ultimately, eight RhiPSC lines were derived from 4 donor rhesus monkeys (n = 2 WT, n = 2 R406W; two clonal lines per donor) and fully characterized according to ISSCR standards. RhiPSC stemness and genetic stability was best maintained on mouse embryonic fibroblast feeders in Universal Primate Pluripotency Stem Cell medium, as opposed to Essential 12 medium supplemented with IWR1, which produced cytogenetic abnormalities. Rhesus neural progenitor cells were generated using a monolayer protocol and expressed PAX6 and NESTIN after 21 days of differentiation. Our reliable method will be useful to labs seeking to derive RhiPSCs for preclinical studies. Overall, the RhiPSCs generated from MAPT R406W carriers will be a critical resource for evaluating the molecular underpinnings of tau-related neurodegeneration across primate species."

"abstract_text": "ID: 42589549\nTitle: Molecular Mechanisms Underlying Antimicrobial Resistance in Mycobacteria.\nAbstract: Antimicrobial resistance in mycobacteria arises from a complex interplay of intrinsic and acquired mechanisms that collectively limit the efficacy of current therapeutic options. Intrinsic resistance is largely driven by the low permeability of the mycobacterial cell envelope, the activity of efflux pumps, and the presence of drug-modifying enzymes, which together restrict intracellular drug accumulation and contribute to broad baseline tolerance. This review integrates resistance mechanisms of both M. tuberculosis and M. abscessus, two clinically relevant mycobacteria that share core molecular pathways while exhibiting species-specific determinants that complicate treatment. Additional intrinsic factors, including biofilm formation and stress-induced adaptive responses, further enhance persistence and reduce susceptibility to multiple drug classes. Acquired resistance predominantly results from chromosomal mutations affecting drug targets or prodrug activation pathways, such as katG, inhA, rpoB, gyrA, and pncA in Mycobacterium tuberculosis, leading to high rates of multidrug-resistant and extensively drug-resistant disease. In nontuberculous mycobacteria, species-specific determinants-including inducible macrolide resistance mediated by erm(41) in M. abscessus, plasmid-mediated erm (55) variants, rrl and rrs mutations, diverse enzymatic inactivation systems, and regulatory alterations in the MarR family that result in inducible resistance to drugs such as ethionamide -generate highly variable resistance profiles that complicate treatment. Recent advances in molecular diagnostics, including PCR-based assays, whole-genome sequencing, CRISPR-based diagnostic platforms, AI-assisted diagnostics, and emerging multi-omics approaches, have improved the detection of resistance-associated mutations and enhanced understanding of mycobacterial pathophysiology. In parallel, new therapeutic agents and optimized regimens offer promising avenues to overcome resistance, although emerging resistance to novel drugs underscores the need for continued surveillance. This review synthesizes current knowledge on the molecular basis of resistance in M. tuberculosis and NTM, highlighting implications for diagnosis, treatment, and future research."

"abstract_text": "ID: 42589509\nTitle: Modeling Inherited Disorders of Post-Lanosterol Cholesterol Biosynthesis: From Animal Models to Patient-Derived Stem Cells.\nAbstract: Altered post-lanosterol cholesterol biosynthesis causes a heterogeneous group of rare inherited metabolic disorders, including Smith-Lemli-Opitz syndrome, desmosterolosis, lathosterolosis, and congenital hemidysplasia with ichthyosiform nevus and limb defects syndrome. These conditions are characterized by impaired cholesterol synthesis together with the accumulation of disease-specific sterol intermediates. Current experimental and clinical evidence suggests that pathogenesis reflects both cholesterol insufficiency and sterol-mediated toxicity, including oxidative stress, perturbed developmental signaling, membrane dysfunction, and impaired neurodevelopment. Experimental models have played a central role in elucidating these mechanisms and in evaluating emerging therapeutic strategies. This review provides a comprehensive overview of currently available experimental models used to investigate inherited cholesterol biosynthesis disorders, including genetically engineered animal models, patient-derived fibroblasts, immortalized and CRISPR/Cas9-edited cell lines, and induced pluripotent stem cell-based systems. Particular emphasis is placed on Smith-Lemli-Opitz syndrome, the most extensively studied disorder within this group, while recent advances in modeling desmosterolosis, lathosterolosis, and congenital hemidysplasia with ichthyosiform nevus and limb defects syndrome are also critically discussed. We compare the strengths and limitations of each experimental platform, highlighting their contributions to understanding sterol metabolism, developmental abnormalities, and cell-type-specific disease mechanisms. Finally, we discuss current challenges and future perspectives, including the development of patient-specific induced pluripotent stem cell models, genome editing approaches, and next-generation multicellular systems. Collectively, this review provides an updated framework for selecting appropriate experimental models to investigate cholesterol biosynthesis disorders and accelerate the development of mechanism-based therapeutic strategies."

No approved therapy restores myocardium lost to infarction. The adult heart replaces cardiomyocytes at approximately 1% per year in young adults, declining to about 0.45% per year with ageing, far below what is needed to recover the more than one billion cells destroyed by a large myocardial infarction. Cell-based regenerative strategies have been investigated for more than two decades, encompassing bone marrow mononuclear cells (BM-MNCs), mesenchymal stromal cells (MSCs), cardiac progenitor cells, cardiosphere-derived cells (CDCs), skeletal myoblasts, and induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs). Safety has been consistent. Efficacy has been modest and variable: the CADUCEUS trial demonstrated scar mass reduction with CDCs without proportionate ejection fraction improvement; the Phase 1/2 POSEIDON trial confirmed MSC safety in 30 patients; and the Phase 3 DREAM-HF trial, enrolling 537 patients, failed its primary endpoint (HR 1.2, p = 0.406). Mechanistic work has established that transplanted cells engraft poorly and exert their benefit principally through paracrine signalling mediated by secreted extracellular vesicles and exosomes carrying microRNAs, trophic factors, and immunomodulatory proteins. For iPSC-CMs, electrophysiological immaturity and arrhythmogenic risk in primate models remain unresolved barriers. Emerging strategies include CRISPR-engineered hypoimmune iPSC lines, bioengineered cardiac patches, injectable hydrogel scaffolds, and engineered exosome platforms. This review provides a comprehensive synthesis of preclinical and clinical evidence, examines translational barriers, and identifies the scientific and regulatory priorities required before these therapies can enter routine clinical practice."

This review summarizes the clinical development of novel treatments for both non-transfusion-dependent and transfusion-dependent \u03b2-thalassemia, including approved therapies, agents in active development, and programs that have been discontinued. Disease-modifying strategies have focused on improving ineffective erythropoiesis, correcting iron dysregulation, and restoring red blood cell metabolism. Luspatercept and mitapivat have demonstrated clinically meaningful improvements in hemoglobin levels and reduction of transfusion burden and are now approved in multiple jurisdictions. Additional pyruvate kinase activators, such as etavopivat, are undergoing clinical evaluation. Curative approaches have advanced substantially through gene addition, gene editing, and base editing technologies. Approved therapies, including betibeglogene autotemcel and exagamglogene autotemcel, have achieved high rates of durable transfusion independence, while emerging platforms aim to further improve efficacy, safety, and accessibility. At the same time, several promising approaches targeting fetal hemoglobin induction, iron metabolism, and ineffective erythropoiesis have failed to demonstrate sufficient clinical benefit despite preclinical proof of concept, highlighting the complexity of therapeutic development in \u03b2-thalassemia. Future priorities include refining patient selection, generating real-world and comparative effectiveness data, developing clinically meaningful response criteria, expanding pediatric access, and addressing the substantial cost and accessibility challenges associated with novel therapies."

Beyond direct cytotoxicity, this photochemistry can be repurposed for on-demand cargo release from lipid nanocarrier systems, enabling spatiotemporal control over therapeutic delivery that is not achievable with conventional lipid nanoparticles. This protocol presents methods for fabricating and characterising two distinct verteporfin (VP)-integrated lipid nanoparticle formulations: (1) light-triggered liposomes composed of DOTAP, DOPE, cholesterol, and VP for delivery of CRISPR-Cas9 ribonucleoprotein (RNP) complexes; and (2) X-ray-triggered liposomes composed of DOTAP, DOPC, VP, and gold nanoparticles for controlled chemotherapy drug release. Upon activation at 690 nm (visible light) or by clinical X-ray radiation (6 MeV), VP generates singlet oxygen that oxidises unsaturated lipid components, destabilising the nanoparticle membrane and releasing encapsulated cargos. Protocols are provided for liposome formulation by thin-film hydration and membrane extrusion, physicochemical characterisation, light- and X-ray-triggered cargo release assessment, in vitro gene knockout in human cells, and in vivo validation using a quantitative zebrafish visual reporter system and a mouse xenograft tumour model. Representative results demonstrate knockout of up to approximately 326 slow-muscle fibres per zebrafish embryo via light activation and significant tumour growth suppression via X-ray-triggered doxorubicin release.The clinical precedent for 689-690 nm verteporfin activation in the eye motivates evaluation of this platform for ophthalmic delivery, although retinal biodistribution, pharmacokinetics, and large-animal safety remain to be established. These methods provide an experimental approach with translational potential for externally controlled therapeutic cargo release."

Although stable transformation in maize is no longer a major obstacle, there remains a need for accessible and efficient methods for academic laboratories. Here, we present the GGB\u00a0system, a rapid and efficient approach optimized for immature embryo transformation in B104 and other maize lines. This system combines two distinct morphogenetic regulators, the wheat GRF4-GIF1 chimera and the maize BABY BOOM (BBM) transcription factor (hence the name \"GGB\") with a modified QuickCorn protocol, enabling regeneration of transformed maize plantlets in c. 2 months with an efficiency 7-fold higher than when compared to either morphogenic factor used in isolation. Expression of both regulators did not significantly affect development, eliminating the need to excise them after regeneration. However, transmission of the transgenic GGB construct through pollen was significantly reduced, potentially aiding transgenic line containment. We show that the GGB system is adaptable for CRISPR-Cas9 editing and reporter line generation. Furthermore, stable GGB transformants exhibited high leaf regeneration capacity via somatic embryogenesis. RNA-seq time-course profiling of GGB leaf cultures identified additional factors that could promote regeneration and led to the discovery of asparagine and trehalose as additional media components that significantly enhanced leaf regeneration."

Polycomb repressive complex 1 (PRC1)-mediated H2AK119ub1 has been implicated in restraining entry into the 2C-like state through Pcgf6, yet the factors governing exit from this state and loss of totipotency remain poorly defined. Here, we show that among the six Pcgf paralogs, Pcgf5, which is most prominently upregulated in 2CLCs and forms an MERVL-driven chimeric transcript (Pcgf5MT2C_Mm) during ZGA in 2-cell embryos, controls exit from the 2C-like state in mouse ESCs. Using a reporter ESC line carrying MERVL-tdTomato and Zscan4c-EGFP (MtZG), we manipulated Pcgf5 dosage bidirectionally. Doxycycline (Dox)-inducible overexpression (OE) of Pcgf5 reduced the double-positive (DP) 2C-like population. Conversely, CRISPR-mediated knockout (KO) of Pcgf5 by targeting a common exon shared by all Pcgf5 variants (hereafter, total Pcgf5) increased the DP population. Time-lapse imaging directly confirmed that these changes reflected genuine differences in duration of the 2C-like state: OE shortened, whereas KO prolonged, the time cells spent in this state. These findings reveal that a Polycomb group factor controls not only entry into but also exit from the 2C-like state."

This study aims to assess the Taif population's opinion on gene editing and their knowledge of genetic modification. In this cross-sectional study, a questionnaire was distributed online from March 2, 2024, to June 15, 2024, to 747 residents of Taif City aged 18 and older. Among the respondents, 14.7% reported that they or their family members suffer from a hereditary disease, and 65.7% either work or study in the healthcare field or have a family member involved in healthcare. Additionally, 50.7% had previously heard of genetic modification. Marital status, number of children, and education level did not significantly influence opinions on genetic editing, whereas affiliation with the healthcare field was significantly associated with greater acceptance\u00a0(p\u2009=\u20090.023), while a family history of hereditary disease showed a trend toward significance (p\u2009=\u20090.055).

However, opinions are more divided on non-disease traits. Many respondents expressed interest in enhancing intelligence (73.8%) and strength (75.8%), as well as altering height (67.8%) and hair color (60.7%). While support was strong for therapeutic use, opinions were divided on enhancement, reflecting ethical tension despite high interest in modifying non-disease traits. Notably, 50.7% believed that using genetic editing for non-medical purposes crosses ethical boundaries and exceeds nature's limits. Awareness of gene-editing techniques was not significantly associated with acceptance (p\u2009=\u20090.108). In conclusion, public acceptance of gene editing in Taif is high, particularly among healthcare-affiliated individuals. Increasing public awareness remains essential to bridge ethical concerns and support informed engagement."

Although \"Zero Hallucinated Moneyshot Quotes\" is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Hypothesis: Repurposing IVF screening tools to verify CRISPR-corrected induced pluripotent stem cells (iPSCs), combined with in vitro gametogenesis, may potentially create disease-free germlines that could eradicate heritable hematological mutations in future generations, such as sickle cell disease.\"\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe convergence of CRISPR-mediated genome editing, hiPSC technology, and in vitro gametogenesis (IVG) offers a theoretical pathway for germline modification to prevent hereditary transmission of hemoglobinopathies. Current literature confirms the feasibility of CRISPR correction in hematological progenitors and the specification of primordial germ cell-like cells (hPGCLCs) from hiPSCs. However, the translation of these combined technologies into a multi-generational curative strategy for human sickle cell disease remains speculative, constrained by bioethical regulations and the technical requirement for further validation of long-term germline maturation and safety.\n\n### [INTRODUCTION & JUSTIFICATION]\nGene therapy for \u03b2-haemoglobinopathies is based mainly on two strategies: gene addition and gene editing. A technological landmark was achieved when the Food and Drug Administration (FDA) approved the first CRISPR-based gene therapy (exa-cel) to edit erythroid specific enhancer region of BCL11A in hematopoietic stem cells. While this current standard of care provides durable remission for somatic patients, it does not address the hereditary transmission of the HBB mutation. The integration of iPSC technologies suggests an avenue for future germline-level interventions. As noted, one of the first embryonic lineages to be specified in the human embryo is the germ cell lineage, marked by the induction of the primordial germ cells (PGCs). Recent advancements have led to the development of defined protocols that mimic early embryonic development and allow the specification of transcriptomically and epigenetically validated human primordial germ cell-like cells (hPGCLCs). This provides a foundational mechanism for potentially generating germlines. Furthermore, researchers have demonstrated that these results establish a scalable strategy for generating fetal granulosa-like supporting cells from hiPSCs and provide an effective and multi-generational safety framework for oocyte-contact IVM interventions. Although advancements in scientific research, especially gene editing and in-vitro gametogenesis (IVG), are not yet fully applicable, their potential future use appears to pose significant bioethical questions. The gap remains between current somatic gene editing, which is clinically validated for SCD, and the prospect of germline replacement, which lacks clinical authorization and human-validation data.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Current curative gene therapies for SCD (e.g., exa-cel) function through hematopoietic stem cell editing, not germline alteration.\n* CRISPR-mediated editing has been successfully applied to produce humanized DMD mouse models with clinical sequence specificity.\n* The use of ovarian support cells (OSCs) derived from hiPSCs has been shown to improve in vitro maturation outcomes, providing a potential helper-cell platform for gametogenesis.\n* Studies have successfully utilized CRISPR to ablate genes in chicken PGCs, demonstrating that germline-restricted suicide-gene cassettes can generate sterile surrogate hosts.\n* The \"14-day rule\" and other regulatory frameworks significantly limit the current translation of embryological research into clinical reproductive medicine.\n* Synthesis errors in ssODNs are a source of untoward variation in HDR-mediated gene editing, emphasizing the need for rigorous quality control beyond current standards.\n* Porcine expanded potential stem cells (pEPSCs) represent a versatile platform for multiplex genome editing, showing that stem cells can maintain genetic stability through multiple edits.\n* Mechanistic links exist between APP dosage and Notch signaling in iPSC-derived neural models, highlighting that gene dosage effects must be considered alongside mutation correction.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Conventional treatments, such as blood transfusions, iron chelation, fetal haemoglobin induction, and allogeneic haematopoietic stem cell transplantation, have improved outcomes but remain limited by treatment-related toxicity, donor availability, and incomplete curative potential. Methods: A narrative literature review was conducted using PubMed up to 2025. Search terms included \"sickle cell disease,\" \"sickle cell anemia,\" \"\u03b2-thalassemia,\" \"transfusion-dependent beta-thalassemia,\" \"gene therapy,\" \"gene addition,\" \"gene editing,\" \"CRISPR-Cas9,\" \"lentiviral vector,\" \"children,\" \"paediatric,\" and \"pediatric.\" Relevant clinical trials, reviews, consensus statements, and guidelines were selected and qualitatively analysed. Results: Gene therapy for \u03b2-haemoglobinopathies is based mainly on two strategies: gene addition and gene editing. Gene addition uses lentiviral vectors to introduce functional or modified \u03b2-globin genes into autologous haematopoietic stem cells, whereas gene editing targets regulatory pathways, particularly BCL11A, to reactivate fetal haemoglobin synthesis or correct disease-causing mutations. Clinical studies have shown encouraging outcomes, including transfusion independence in many patients with \u03b2-thalassaemia and marked reduction or elimination of vaso-occlusive crises in sickle cell disease. Paediatric and adolescent data are increasingly promising, although still limited. Conclusions: Gene therapy is reshaping the treatment landscape of \u03b2-haemoglobinopathies by offering a personalised and potentially curative approach. However, long-term safety, conditioning toxicity, fertility preservation, accessibility, costs, and implementation in high-prevalence regions remain critical challenges. Further studies are needed to optimise patient selection and expand equitable access.\n\nID: 42494498\nTitle: CRISPRing through time: How cutting-edge technology is revolutionizing life sciences and medicine.\nAbstract: Given the plethora of emerging technologies, none have truly captured the minds as CRISPR. From the groundbreaking research, the ultimate battle of the prizes and patents to a number of books, the science of CRISPR continues to be significant in the biomedical field. For many decades now, the emergence of synthetic biology as an intervention to correct diseases has become the foundation of biomedical research. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based genetic editing has become a common place for routine investigation of scientific hypotheses in pre-clinical settings. More recently, CRISPR-based diagnostic testing kits for SARS-CoV-2 have showcased a translational output. Furthermore, a technological landmark was achieved when the Food and Drug Administration (FDA) approved the first CRISPR-based gene therapy (exa-cel) to edit erythroid specific enhancer region of BCL11A in hematopoietic stem cells, introduced in patients suffering from sickle cell anemia to achieve durable remission. In this review, we provide a snapshot into the most important milestones along the journey of CRISPR from its discovery in bacteria to its usage in precision medicine. The intervention of machine learning tools has now intertwined complex biology with high-throughput scalable outputs. Given the vast amount of information on CRISPR, we try to pin down key take-home messages for scientists as well as non-scientist readers. This review article attempts to understand why and how CRISPR remains significant and seamlessly integrates in the emerging era of new technologies.\n\nID: 42450173\nTitle: CRISPR/Cas9-Based Genome Editing: Understanding Differences in DNA Repair Pathways, Profiles, and Outcomes.\nAbstract: Over a decade of advances in Clustered Regularly Interspersed Short Palindromic Repeats (CRISPR) and CRISPR-associated protein 9 (Cas9)-based technologies have culminated in the first-ever FDA-approved CRISPR/Cas-based therapy. Aside from this approved therapy for sickle cell anemia, several CRISPR/Cas-based therapies are currently under development or testing for a range of chronic diseases, including viral diseases like human immunodeficiency virus type 1 (HIV-1) infection, genetic diseases like familial hypercholesterolemia, and cancer. The success of these therapies hinges on the effective delivery of CRISPR/Cas9 components to target regions, efficient Cas endonuclease editing, repair profiles generated, and their resulting outcomes. Here, we discuss the factors that influence the generation of CRISPR/Cas9-generated repair edits, the overall profiles, and outcome prediction(s), as well as the analytical tools that have been developed to date. Finally, how this technology has been used towards a functional HIV-1 cure is discussed.\n\nID: 42448317\nTitle: Blood Rheology After Allogeneic Hematopoietic Stem Cell Transplantation or Gene Therapy in Sickle Cell Disease.\nAbstract: Allogeneic hematopoietic cell transplantation (HCT) and autologous hematopoietic stem cell-based gene therapies are potentially curative for sickle cell disease (SCD). Although most patients experience resolution of overt clinical symptoms associated with SCD with donor-dominant myeloid chimerism after undergoing HCT or the induction of a substantial amount of alternative hemoglobin after gene therapy, whether the underlying subclinical physiology is normalized in these individuals is unknown. One approach to evaluating the underlying physiology is to characterize the blood rheology of patients after they receive these therapies. We assessed the rheology of 123 blood samples from 69 patients, of whom 43 underwent HCT (32 from matched related donors, 11 from haploidentical donors) and 11 received gene therapy. The results were compared to those for patients treated with hydroxyurea with optimum fetal hemoglobin response (HUOptimum) (n\u2009=\u200915). Median rheology parameters of recipients of HCT from donors with sickle cell trait (HbAS) were superior to those of gene therapy recipients (elongation index minimum [EImin]: 0.6 vs 0.31; point of sickling [PoS]: 0 vs 26.21) and of the HUOptimum cohort (EImin: 0.6 vs 0.15; PoS: 0 vs 36.2: percentage of dense red blood cells [%DRBC]: 0.9 vs 4.9) (P\u2009<\u20090.05 for all comparisons). Results for the gene therapy and HUOptimum groups were comparable (P\u2009>\u20090.05). Given the substantial number of patients with abnormal rheology and the associations between rheology and SCD-related complications, rheology tests may be included in the follow-up care for HCT and gene therapy recipients.\n\nID: 42273255\nTitle: CRISPR and Fanzor in sickle cell disease: current progress and future prospects.\nAbstract: Advancements in genome editing have established a new frontier for the treatment of various genetic diseases, including sickle cell disease (SCD). SCD, the most prevalent monogenic blood disorder, causes severe pain, organ damage, and reduced life expectancy. The recent clinical approval of clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9-based gene therapies for severe sickle cell anemia marks a significant milestone in treating genetic diseases. Despite these breakthroughs, limitations in CRISPR technology persist, requiring further innovation. Alternative approaches, such as the Fanzor (Fz) system, are being developed to complement CRISPR's capabilities. Unlike CRISPR, which is typically encoded within prokaryotic organisms, Fz is encoded in the eukaryotic genome, offering a universal RNA-guided mechanism applicable across all life kingdoms. Fz's eukaryotic origin may facilitate more efficient delivery across diverse cell types and tissues, enhancing its therapeutic potential. Here, we will review the current successes and limitations of the CRISPR technology in editing mutation associated with SCD. Additionally, we will explore the potential role of Fz as a genome-editing tool for SCD, a field where its application has not yet been studied.\n\nID: 42113606\nTitle: Generation of human primordial germ cell-like cells from cumulus and blood cell-derived isogenic human induced pluripotent stem cells\u2020.\nAbstract: The recent development of in vitro germ cell differentiation from pluripotent stem cells opened the human reproduction field to mechanistic investigations. In combination with induced pluripotent stem cell (hiPSC) reprogramming, in vitro gametogenesis provides an avenue for patient-specific disease modeling approaches. However, further advancements are required, as current protocols are limited to early stages of germ cell development. To get one step closer to this goal, here we aimed to identify optimal conditions for generating high-quality hiPSC lines capable of in vitro germ cell differentiation. We isolated two clinically available somatic cell types, peripheral blood-derived mononuclear cells and cumulus cells from the same female donor, and reprogrammed them into human induced pluripotent stem cells (hiPSCs). We then assessed their differentiation into ectoderm, mesoderm, and endoderm, and evaluated their X-chromosome inactivation status, a critical indicator of stem cell quality. Finally, we compared the capacity of PBMC- and cumulus-derived hiPSCs to differentiate into human primordial germ cell-like cells (hPGCLCs). We found that despite variability between cell lines, hiPSCs from both cell types were capable of generating hPGCLCs and that variations in X-chromosome state did not appear to generally interfere with the process. Our findings provide insight into germ cell differentiation from different clinically available starting materials guiding future patient-specific studies of fertility disorders.\n\nID: 42083602\nTitle: Genetic Engineering in Hematopoietic Stem Cells for \u03b2-Hemoglobinopathies Treatment: Advances, Challenges, and Clinical Translation.\nAbstract: \u03b2-hemoglobinopathies rank among the most prevalent inherited blood disorders globally. Traditional management strategies are primarily palliative and often associated with significant challenges, including iron overload and limited long-term efficacy. Allogeneic hematopoietic stem cell transplantation (HSCT) is a potentially curative option for transfusion-dependent patients, but its broader applicability is constrained by factors that limit its use. Utilizing viral vectors and gene-editing tools, particularly CRISPR-Cas9 technology, researchers have developed therapies that target the root causes of these disorders. These innovative approaches have demonstrated substantial therapeutic potential, accompanied by favorable safety profiles, in clinical settings. Since the initial investigations, the genome editing tool has rapidly advanced for genetic abnormalities, particularly monogenic blood diseases, including \u03b2-hemoglobinopathies. This method suggests an approach with lower concerns in viral gene integration and insertional mutagenesis issues. This review comprehensively surveys the therapeutic strategies for \u03b2-thalassemia and sickle cell disease (SCD) currently in preclinical and clinical development, with a focus on the evolving treatment paradigm. Looking forward, critical research priorities include optimizing the efficiency and specificity of gene-editing platforms and pioneering novel delivery systems to guarantee both therapeutic efficacy and clinical safety.\n\nID: 41808594\nTitle: The Impact of Aging on Organ Systems in Sickle Cell Disease: a Comparative Review of Physiological Adaptation and Dysfunction.\nAbstract: Sickle cell anemia (SCA) is a progressive, systemic disorder that can lead to multi-organ dysfunction. While it has traditionally been most prevalent in regions where malaria is endemic, recent epidemiological studies have shown an increasing disease prevalence in non-endemic areas, primarily attributed to global human migration patterns. The severity of SCA typically worsens with age. In early childhood, affected individuals may present with renal hyperfiltration, neurocognitive delays, cardiac remodeling, and skeletal fragility. The presence of these early manifestations often predicts the development of chronic complications later in life, including splenic atrophy, neurodegeneration, and impaired cerebral perfusion. Adequate management of SCA begins with universal newborn screening programs, enabling early detection and the initiation of appropriate interventions. Therapeutic advancements, ranging from disease-modifying agents such as hydroxyurea to curative options including gene therapy and stem cell transplantation, have significantly improved clinical outcomes; however, long-term morbidity remains a significant challenge. This review aimed to explore the effect of aging on pathophysiological changes and the onset of organ-specific complications in SCA patients. It highlights the importance of age-tailored monitoring and a multidisciplinary approach to detect early signs of organ damage, prevent irreversible complications, and consequently improve overall quality of life.\n\nID: 41728147\nTitle: Gene Therapy for Sickle Cell Anemia in India - Current Status and Challenges.\nAbstract: Sickle cell disease (SCD) is a critical monogenic disorder impacting millions of people in India and severely compromising the quality of life for the patients. At present, the only available curative treatment for sickle cell disease (SCD) is allogenic hematopoietic stem cell transplantation. However, recent advancements in gene therapy offer promising prospects for curing the disease, either through the correction of the pathogenic mutation or the induction of Fetal hemoglobin production. This review focuses on the gene addition and gene editing technologies being currently employed in the treatment of SCD, with a particular emphasis on therapeutic interventions that are undergoing clinical trials globally. Furthermore, this review provides an insight into the extensive research efforts being undertaken in India to develop curative therapies for SCD, while also addressing the significant challenges faced by the healthcare system and patients, including ethical, socio-economic, and regulatory barriers unique to the Indian context.\n\nID: 41593679\nTitle: Adaptation of lentiviral vectors for viral gene therapy and their impact on host cell biology.\nAbstract: Lentiviral vectors (LVVs) are used as a viral gene therapeutic and were derived from human immunodeficiency virus subtype 1 (HIV-1). LVVs are used to deliver and induce the stable expression of transgenes through genome integration. Current clinical LVV delivery systems do not include HIV-1 major accessory genes; however, critical structural and non-structural HIV-1 proteins are encoded by the 4-plasmid combination that composes the 3rd generation LVV transduction systems. LVVs use HIV-1-like mechanisms for viral genome integration and both transgene delivery and expression. LVVs rely on host cell machinery to transcribe and translate transgenes for either knocking down disease-causing genes and/or supplying functional genes in a targeted disease. LVVs integrate into host intronic and intergenic regions due to genomic accessibility, but there are no known biases toward specific target integration motifs. Investigation of LVV integration has uncovered the generation of chimeric LVV-host transcripts and altered host transcript splicing patterns. Several Food and Drug Administration (FDA)-approved LVV-derived therapies are used for treating diseases ranging from beta thalassemia to sickle cell anemia. An increasingly popular application of LVV is in the generation of chimeric antigen receptor (CAR) T cell therapies, which change and enhance T cell antigen specificity and effector function in liquid cancers. In November 2023, all CAR T cell therapies were placed under FDA investigation due to higher-than-expected rates of malignant transformation, hospitalization, and death in treated individuals. LVV integrations driving oncogene expression could be a cause for malignancy development. Current methods for resolving LVV integration patterns are technically limited by the sequencing approach applied allowing for only limited characterization of LVV integration profiles and altered host gene regulation. A comprehensive understanding of LVV integration and its consequences is necessary for understanding how these events influence host cell gene regulation and splicing, possibly identifying tunable variables for enhanced positive clinical outcomes. Here, we review the development of LVV systems, what is known about LVV integration patterns, technologies used to characterize patterns of LVV integration, and what is understood about the subsequent impact on host cell gene regulation and its potential linkage to patient malignancies.\n\nID: 41416641\nTitle: The road to restore male fertility using in vitro-derived germ cells.\nAbstract: Human-induced pluripotent stem cells (hiPSCs) offer immense potential in reproductive medicine, particularly for males who lack germ cells and cannot achieve biological parenthood through conventional ARTs. Early efforts to derive human germ cells from stem cells were hindered by low efficiency, subpar characterization, and the lack of standardized differentiation approaches. However, recent advancements have led to the development of defined protocols that mimic early embryonic development and allow the specification of transcriptomically and epigenetically validated human primordial germ cell-like cells (hPGCLCs). Current research focuses on maturing hPGCLCs in vitro, particularly within 3D culture systems that resemble their physiological microenvironment, with the aim of producing transplantable hiPSC-derived spermatogonial stem cells (SSCs) or differentiating them to sperm. At the same time, researchers are also testing whether hiPSCs generated from infertile patients can resume germline differentiation. This narrative review aimed to summarize the key efforts and remaining challenges in differentiating male germ cells from human pluripotent stem cells (hPSCs), with a particular focus on defined and validated protocols for hPGCLC specification. In parallel, we addressed key safety and ethical considerations that must be accounted for the development of clinical applications. A deeper understanding of the approaching therapeutic use of hiPSCs in reproductive medicine is essential for developing novel regenerative fertility strategies. PubMed, Scopus, and Web of Science were searched for studies attempting germ cell differentiation from hPSCs using relevant keywords ('stem cells', 'human pluripotent stem cells', 'human embryonic stem cells', 'human induced pluripotent stem cells', 'somatic cell reprogramming', 'infertility', 'germline', 'spermatogenesis', 'germ cells', and 'primordial germ cells'). No time period restriction was established. Studies with an exclusive focus on female germline differentiation were excluded. To maintain a human-focused perspective, only key animal studies are presented. The literature reveals a clear segregation among protocols for deriving germ cells from hPSCs, particularly between earlier studies lacking standardized differentiation conditions and characterization, and the most recent, defined protocols having transcriptomic and epigenetic validation against in vivo hPGCs. Moreover, during the last decade, the field has seen remarkable progress, with multiple efforts aimed at maturing hPGCLCs, closely recapitulating late male embryonic germline development. Additionally, hiPSCs derived from male patients at risk of infertility, particularly those without underlying genetic syndromes, generally retain the capacity for early germline commitment. While attempts at maturating patient germ cells beyond the hPGCLC state remain limited, the rapid pace of discovery and refinement in recent years suggests that further breakthroughs, including clinically applicable fertility restoration strategies, are likely to be achieved in the near future. The ability to generate hiPSCs from infertile patients and to specify them into hPGCLCs supports the feasibility of obtaining hiPSC-derived SSCs for future therapeutic use. These advances raise important ethical, regulatory, and societal questions that must be actively discussed among researchers, clinicians, policymakers, and the general public to ensure responsible and equitable access to these technologies.

While individuals with sickle cell trait are usually asymptomatic, those with homozygous disease may experience chronic haemolytic anaemia, recurrent vaso-occlusive crises, and progressive organ injury. Current standards of care, including hydroxyurea therapy, chronic blood transfusions, and allogeneic haematopoietic stem cell transplantation (HSCT), have substantially improved survival and reduced complications. However, each approach has limitations, such as incomplete disease control, toxicity, and limited donor availability. Recent advances in non-myeloablative and haploidentical HSCT have expanded curative options, achieving high survival with minimal graft-versus-host disease, though accessibility and cost remain challenges. Emerging gene therapies, particularly lentiviral vector-mediated gene addition and CRISPR-Cas9 genome editing, represent major progress by directly targeting the underlying genetic defect. These autologous approaches eliminate donor-related immune risks and have demonstrated durable haemoglobin correction, near-complete resolution of vaso-occlusive events, and encouraging outcomes in stroke prevention. This review synthesises evidence comparing gene therapies with standard treatments, outlining molecular mechanisms, efficacy, safety, and long-term considerations. Key challenges include stem-cell mobilisation, fertility preservation, conditioning toxicity, and equitable access. Early trials show substantial clinical benefit, improved quality of life, and favourable safety profiles. Emerging in vivo editing technologies may further simplify delivery and enhance global accessibility. Integrating gene therapy into evolving standards of care could transform SCD management, offering realistic prospects for durable remission or cure.\n\nID: 41072772\nTitle: Acute Toxicities of Bone Marrow Donation in Unrelated Donors with Sickle Cell Trait: A Center for International Blood and Marrow Transplantation Research Analysis.\nAbstract: Ethnic minority donors are essential in international donor registries to ensure access to all patients requiring allogeneic stem cell transplantation. Current literature regarding bone marrow (BM) donation-associated pain and toxicity in donors with sickle cell trait (ST), a condition that disproportionally affects minorities, is very limited. Improved communication with potential donors with ST about donation-associated toxicities is important to address misconceptions about donation and may increase the likelihood of participation by minority donors. The aim of this study was to determine the impact of ST on pericollection pain and toxicities experienced by unrelated BM donors. The study population comprised first-time unrelated donors with ST and a subset of unrelated donors without ST from the United States whose BM donation was facilitated by the National Marrow Donor Program (NMDP) between 2010 and 2019. Donors in the control group (ie, donors without ST) were selected for propensity score matching based on age categories, sex, race/ethnicity, and predonation skeletal pain. Logistic regression models were conducted to compare the donors with and without ST for pain and toxicities associated with donation after adjusting for differences in donor characteristics. Descriptive statistics were used to report serious adverse events. Univariate probabilities of complete recovery from donation were calculated using the Kaplan-Meier estimator. A total of 346 BM donors (87 with ST and 259 without ST) were included in this study. The majority of the donors in both cohorts were male (52%), African American (64%) and overweight or obese (77%). Stem cell collection parameters, including BM harvest volume, requirement for autologous blood transfusion postharvest, and duration of anesthesia were comparable between the 2 cohorts. At 2 days postdonation, 68.9% of BM donors with ST and 83.1% of BM donors without ST experienced skeletal pain (P < .01). Although grade 1 pain was more common in donors without ST (51.4% vs 35.6%), grade 2-4 pain was comparable between the 2 cohorts (P = .98). At 1 month postdonation, the incidence of grade 2-4 pain was also comparable between the 2 cohorts (P = .25). By 6 months postdonation, the rates of persistent pain were low, at 5.7% in donors with ST and 6.5% in donors without ST. Donation-related modified toxicity criteria (MTC) at 2 days postdonation were comparable between the 2 cohorts (P = .59). The median time to recovery was 23.5 days in donors with ST and 22.0 days in donors without ST. The rate of reported AEs was slightly higher in donors with ST (2.29% versus 1.59%). BM donation appeared to be well tolerated in donors with ST, with similar rates of postdonation pain and general symptoms as seen in donors without ST. Moreover, BM donation carries a low risk of perioperative mortality, comparable to that observed in donors without ST. This report provides, to our knowledge, the first comprehensive analysis of the impact of ST on toxicities and recovery after BM donation and adds to our understanding of the safety of BM donation in donors with ST.\n\nID: 40834880\nTitle: Gene therapy for HbSC disease and other compound heterozygous sickle hemoglobinopathies: a time for inclusion.\nAbstract: Two gene therapy products have been approved by the US Food and Drug Administration for sickle cell disease. Nearly all patients in the clinical trials that led to approval either were sickle hemoglobin (HbS) gene homozygotes (sickle cell anemia) or had HbS-\u03b20 thalassemia. HbSC disease, caused by compound heterozygosity for HbS and hemoglobin C genes, is the second most common genotype of sickle cell disease. Gene therapy has not been tested in patients with HbSC disease who are severely symptomatic. We discuss the pathophysiology and clinical features of HbSC disease and how gene therapy is likely to provide a curative option for some individuals. We also discuss the mechanism through which fetal hemoglobin (HbF) and HbF-like HbA (HbAT87Q) might mitigate adverse clinical outcomes and end-organ damage in patients with HbSC disease and other compound heterozygous sickle hemoglobinopathies.\n\nID: 40699667\nTitle: Advances in Gene Therapy with Oncolytic Viruses and CAR-T Cells and Therapy-Related Groups.\nAbstract: Cancer gene therapy is attracting considerable attention as a new treatment method for overcoming intractable cancers. CAR-T cell therapy has already achieved remarkable results, particularly for hematological tumors. Because CAR-T cells can increase within the body, they have the advantage of requiring only a single administration. In addition, CAR-T cell therapy targeting the CD19 antigen has been established for relapsed or refractory disease in young people with CD19-positive acute B-cell leukemia (B-acute lymphoblastic leukemia, B-ALL) and diffuse large B-cell lymphoma (DLBCL). In addition to CAR-T cell therapy, oncolytic viruses represent a promising approach for cancer treatment, with some already in clinical use and others being researched for their potential benefits. These viruses infect and kill cancer cells, triggering an immune response that helps the body recognize and fight cancer. Oncolytic virus therapy is a form of immunotherapy that uses modified viruses to target and destroy tumor cells while potentially stimulating antitumor immune responses. These viruses have shown promising activity in clinical trials, with some approved for specific cancers like melanoma. Research is ongoing to improve their efficacy, expand their use to other cancer types, and overcome the logistical challenges associated with their delivery. Gene therapy can potentially treat diseases caused by recessive gene disorders like cystic fibrosis, hemophilia, muscular dystrophy, and sickle cell anemia, as well as acquired genetic diseases, such as cancer and viral infections like acquired immunodeficiency syndrome (AIDS).\n\nID: 40469750\nTitle: Assessing the safety of gene therapy vectors expressing an enhanced gamma-globin gene for the cure of sickle cell anemia.\nAbstract: \n\nID: 40304595\nTitle: Alloimmunization as a barrier to gene therapy in sickle cell disease.\nAbstract: Alloimmunization is prevalent in patients with sickle cell disease (SCD) and can be a barrier to gene therapy (GT) due to the necessary transfusion support for successful stem cell collection and infusion. We estimate that standard-of-care GT for an adult with SCD will require an average of 35-45\u2009units of red blood cells over a 6-month period. Institutions should actively plan for these transfusion needs and share information to inform national consensus policies on the management of alloimmunization during GT.\n\nID: 40238672\nTitle: Evaluating the long-term benefits of hydroxyurea in pediatric sickle cell anemia.\nAbstract: Hydroxyurea is the primary disease-modifying medication for sickle cell anemia (SCA), but its long-term effects, particularly how these effects change over time, are not well understood. This study aimed to quantify the effects of hydroxyurea on clinical and laboratory outcomes in children with SCA over a prolonged period of use. We conducted a quasi-experimental study using contemporary difference-in-differences and dynamic event study analyses on a longitudinal cohort of 2147 children with SCA (hemoglobin SS or hemoglobin SS\u03b20, HbSS/HbS\u03b20) from 2010 to 2021. The primary outcomes included emergency department (ED) visits per year, hospital days per year, and annual average hemoglobin concentration. Hydroxyurea use was associated with fewer ED visits per year (average treatment effect on the treated [ATT], -0.36 visit per year; 95% confidence interval [CI], -0.57 to -0.16) and fewer hospital days per year (ATT, -0.84 d/y; 95% CI, -1.51 to -0.17) with sustained effects over time. On average, the hemoglobin concentration increased with hydroxyurea use (ATT, 0.56 g/dL; 95% CI, 0.39-0.73), but the sustained effect was observed only among the subgroup with laboratory markers of good adherence. This study demonstrates that hydroxyurea has sustained clinical benefits in reducing ED visits and hospital days across years of use in children with SCA. These findings provide perspective for clinicians and families regarding the long-term efficacy of hydroxyurea in pediatric SCA management and underscore the importance of ongoing adherence counseling to optimize clinical benefit. Furthermore, this study design provides a methodological framework for rigorously and causally evaluating other SCA-specific treatments, such as stem cell transplant and gene therapy, in real-world settings.\n\nID: 40213215\nTitle: Managing emotional and physical stress in sickle cell anemia: a review of effective strategies and approaches.\nAbstract: Sickle cell anemia (SCA) is a genetic blood disorder characterized by recurrent pain episodes, chronic complications, and significant emotional and physical stress. This review article explores effective strategies for managing both the emotional and physical aspects of stress in SCA patients. A comprehensive literature search was conducted across multiple databases, including PubMed, Scopus, and Google Scholar, using keywords such as \"sickle cell anemia\", \"stress management\", \"psychological support\", and \"pain management\". Emotional stress in SCA arises from chronic pain, frequent hospitalizations, and disease uncertainty, leading to conditions such as anxiety and depression. Effective management of emotional stress involves a combination of psychological counseling, cognitive-behavioral therapy (CBT), and support groups, which help patients develop coping strategies and address the mental health challenges of living with a chronic illness. This review evaluates various psychological interventions and their impact on patient outcomes, emphasizing the need for integrated mental health support in the management of SCA. Physical stress in SCA is primarily due to acute vaso-occlusive crises and chronic pain, which require effective pain management and preventive measures. The review explores pharmacological treatments, such as opioids and hydroxyurea, as well as nonpharmacological approaches, including physical therapy and lifestyle modifications. Additionally, the article discusses innovative therapies like gene therapy and stem cell transplantation, which hold promise for long-term disease management.\n\nID: 40176947\nTitle: Preclinical efficacy of a modified gamma-globin lentivirus gene therapy in Berkeley sickle cell anemia mice and human xenograft models.\nAbstract: We previously showed correction of sickle cell anemia (SCA) in mice utilizing a lentiviral vector (LV) expressing human \u03b3-globin. Herein, we made a G16D mutation in the \u03b3-globin gene to generate the G16D mutation (GbGM) LV to increase fetal hemoglobin formation. We also generated an insulated version of this LV, GbGMI, inserting a 36-bp insulator from the Foamy virus in the long terminal repeats of the LV. Preclinical batches of GbGM and GbGMI LV showed both were highly efficacious in correcting SCA in mice, with sustained gene transfer in primary transplanted SCA mice and high hematopoietic stem cell (HSC) transduction in colony-forming unit-spleen in secondary transplanted mice. CRISPR-mediated targeting of the proviruses into the LMO2 proto-oncogene showed remarkably reduced LMO2 activation by both insulated and uninsulated LV, compared to the SFFV \u03b3-RV vector targeted to the same locus. We therefore used the GbGM LV to perform preclinical human CD34+ gene transfer. We assessed gene transfer and engraftment of human HSCs in two immunocompromised mouse models: persistent stable GbGM-transduced cell engraftment was comparable to that of untransduced cells with no detrimental effects on hematopoiesis up to 20\u00a0weeks post transplant. These robust preclinical studies in mouse and human HSCs allowed its translation into a clinical trial.\n\nID: 42561940\nTitle: From stem cells to somites: Revealing genetic and exogenous factors of human embryogenesis.\nAbstract: Stem-cell-based human embryo models offer an ethically tractable platform for studying early human development. This study employs somitoids, three-dimensional models of human somitogenesis, to investigate how transcriptional programs and culture conditions influence somite formation and segmentation. We show that pre-differentiation culture medium impacts the developmental potential of induced pluripotent stem cells (iPSCs), with StemFit medium and Matrigel embedding outperforming mTeSR Plus medium in generating robust somite-like structures. Strikingly, these differences arise despite only subtle changes in transcriptomic and time-resolved proteomic profiles. P300-based proximity labeling also reveals a largely overlapping set of chromatin-associated regulators across iPSC conditions. In somitoids, enhancer-associated profiling highlights factors linked to somitogenesis, including MESP2 and TBX6. Knockout of three identified regulators, BPTF, RBPJ, and CITED2, demonstrate their essential roles in somite formation. Together, these findings highlight how culture conditions and enhancer-associated networks influence early human development and demonstrate somitoids as a scalable system for functional genomics.\n\nID: 42518039\nTitle: Reprogramming senescent granulosa cells for germ-cell generation.\nAbstract: Oocyte number and quality decline greatly with age. Previously, we demonstrated that granulosa cells (GCs) from young mice could be effectively reprogrammed into chemically induced pluripotent stem cells (GC-CiPSCs), which can generate functional oocytes. Here, we investigated whether GCs isolated from reproductively-aged mice could similarly generate germ cells. Old GC-CiPSCs reprogrammed from GCs isolated from reproductively-aged mice exhibited pluripotent gene expression profiles comparable to those of embryonic stem cells and young GC-CiPSCs. However, old GC-CiPSCs displayed compromised mitochondrial function and a reduced capacity to differentiate into primordial germ cell-like cells (PGCLCs). Mitochondrial enhancement did not improve PGCLC induction efficiency in old GC-CiPSCs. However, inhibiting the ERK/MAPK signaling pathway improved the induction efficiency of PGCLCs from old GC-CiPSCs. These findings demonstrate functional deficits in generating PGCLCs from aged mouse GC-derived iPSCs and identify a strategy to improve PGCLC induction efficiency from senescent GCs.\n\nID: 42513228\nTitle: Breast Cancer: Epidemiology, Molecular Classification, Diagnostics and Evolving Treatment Paradigms.\nAbstract: Breast cancer remains one of the most prevalent malignancies affecting women worldwide and continues to be a leading cause of cancer-related morbidity and mortality. Patients may present with either localized or advanced disease, with clinical outcomes increasingly influenced by molecular subtype and genetic profile. This review highlights the key genetic factors involved in breast cancer, current diagnostic and therapeutic strategies, and promising emerging approaches that may shape future clinical management. Breast cancer diagnosis typically involves clinical breast examination, imaging techniques such as mammography and ultrasound, and confirmatory biopsies. Genetic mutations in specific genes are strongly linked to the development, progression, and metastasis of the disease. Treatment options for localized breast cancer continue to include surgery (lumpectomy or mastectomy) and radiotherapy, combined with systemic therapies tailored to tumor biology, such as endocrine therapy, human epidermal growth factor receptor 2 (HER2)-targeted therapy, and cyclin-dependent kinase (CDK)4/6 inhibitors. For advanced or metastatic breast cancer, recent therapeutic advances include the use of immunotherapy (e.g., immune checkpoint inhibitors), Poly (ADP-ribose) polymerase (PARP) inhibitors for Breast Cancer gene (BRCA)-mutated cancers, antibody-drug conjugates, and novel targeted agents, which have significantly improved patient outcomes in selected populations. Recent findings in breast cancer genetics have highlighted the critical role of germline and somatic mutations, particularly in genes such as BRCA1, BRCA2, phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), and TP53, in driving tumor initiation, progression, and therapeutic response. Molecular profiling and next-generation sequencing technologies have enabled more precise tumor classification and facilitated the development of personalized treatment strategies. Despite these advances, treatment resistance and disease recurrence remain major challenges, particularly in aggressive subtypes such as triple-negative breast cancer. Consequently, ongoing research is exploring alternative and complementary approaches, including nanotechnology-based drug delivery systems, gene editing techniques such as clustered regularly interspaced short palindromic repeats-Cas9 (CRISPR-associated protein 9) (CRISPR-Cas9), cancer vaccines, and the integration of traditional and plant-derived compounds. These strategies aim to enhance therapeutic efficacy, reduce systemic toxicity, and overcome resistance mechanisms.\n\nID: 42475285\nTitle: Protocol For Differentiating Pluripotent Stem Cells Into Primordial Germ Cell-like Cells.\nAbstract: Using human pluripotent stem cell differentiation in vitro has significantly broadened the understanding of lineage specification events that occur during early development in vivo, a period that is extremely challenging to investigate. One of the first embryonic lineages to be specified in the human embryo is the germ cell lineage, marked by the induction of the primordial germ cells (PGCs). The PGCs are the sole founder population of the gametes later in life, and their specification is a critical first step towards the organism's fertility. Here, a robust protocol for generating PGC-like cells (PGCLCs) from human induced pluripotent stem cells (hiPSCs) is described, starting with the initial evaluation of the pluripotent state and cellular characteristics of the hiPSCs to ensure effective PGCLC differentiation. For this, the effects of different cell densities, plate coatings, and hiPSCs used for PGCLC differentiation are discussed. Finally, a workflow for characterization and quantification of hPGCLCs, using immunofluorescence and flow cytometry, is provided. The differentiation protocol focuses on conditions that are easy to establish and test in most laboratories and can be adjusted as necessary. Moreover, this protocol is fast, allowing determination of whether hiPSCs are suitable for PGCLC differentiation. The protocol aims to promote consistency and compatibility in hPGCLC outcomes across different hiPSC lines and culture platforms, ensuring robust yields that support reliable characterization and further optimization of downstream differentiation steps toward successful in vitro gametogenesis in humans.\n\nID: 42369211\nTitle: Exploring the Functional Impact of Individual DDX41 Variants With a Fast and Robust Cell-Based Method.\nAbstract: Germline DDX41 variants are found in up to 4% of patients with acute myeloid leukemia (AML) and myelodysplastic neoplasms (MDSs), with a higher prevalence among males and a late onset. In this study, we analyzed 647 Danish patients with suspected myeloid neoplasms to assess the frequency of germline DDX41 variants and the functional impact of variants of uncertain significance (VUSs) using a cell-based assay, CRISPR-Select. We identified 16 DDX41 variants in 30 patients, 14 of whom were confirmed or predicted as germline variants. Eight germline variants were classified as likely pathogenic/pathogenic (LP/P), and three as VUSs. We generated a monoallelic DDX41 K562 cell line and used it for CRISPR-Select assessment of variant effects on proliferation and survival. Pathogenic variants impaired proliferation, while benign variants did not. Missense variants had a more subtle effect than truncating ones, suggesting hypomorphic phenotypes. One DDX41 VUS had a significant negative effect on proliferation, suggesting it to be pathogenic, while the other two had no effect, suggesting them to be benign. These findings confirm a 2.4% frequency of LP/P DDX41 germline variants in Danish patients and demonstrate the value of CRISPR-Select in distinguishing pathogenic from benign variants.\n\nID: 42327050\nTitle: Attenuated estrogen signaling disrupts placentation and drives trophoblast defects in Down syndrome.\nAbstract: Proper establishment of the primitive placenta and subsequent tissue homeostasis in the mature placenta are critical for successful pregnancy in humans. Placental insufficiency is associated with adverse pregnancy outcomes, including fetal growth restriction, preeclampsia, and pregnancy loss. Moreover, emerging evidence suggests that placental defects are associated with long-term health challenges that manifest well into adulthood; yet the etiologies of such diseases are largely unknown. Defining the mechanistic basis for placental deficiencies, therefore, has important implications for improving both reproductive health and the lifelong well-being of affected children. Down syndrome is characterized by placental defects of unknown mechanistic origin, and notably, individuals with Down syndrome are at increased risk of developing diseases commonly associated with placental insufficiency later in life. Using induced pluripotent stem cells from Down syndrome patients, we found that stem cell-based embryo models (i.e., blastoids) and directed differentiation systems recapitulate trophoblast cell fate defects observed in placentas affected by Down syndrome. Furthermore, we demonstrate that attenuated estrogen signaling contributes to placental syncytialization defects and identify NRIP1, a transcriptional corepressor of estrogen receptor that is located on chromosome 21, as a key driver of trophoblast cell fate defects. Increased gene dosage of NRIP1 in an otherwise diploid cell line phenocopies cell fate defects observed in trophoblasts affected by Down syndrome. Our study suggests that estrogen signaling is a crucial regulator of trophoblast development and may serve as a potential target for therapeutic intervention. Estrogen signaling mediates syncytiotrophoblast fusionHuman iPS cells provide a tractable model for trophoblast defects in Down syndromeTrophoblast differentiation and estrogen signaling are disrupted in Down syndromeIncreased NRIP1 expression is sufficient to induce trophoblast defectsLogsdon and colleagues apply patient-derived induced pluripotent stem cells to recapitulate placentation defects observed in Down syndrome. The authors demonstrate that attenuated estrogen signaling disrupts trophoblast differentiation and identify NRIP1, a gene found on chromosome 21 that dampens estrogen signaling, as a regulator of trophoblast maturation. NRIP1 and estrogen signaling may represent important therapeutic targets for infertility and Down syndrome.\n\nID: 42303162\nTitle: CRISPR Cas9 revolutionizing genetic engineering and therapeutic applications.\nAbstract: Genetic engineering has been transformed by CRISPR-Cas9 technology, offering high precision and adaptability in biological research and therapeutic innovation. Originating from a bacterial defense system, CRISPR-Cas9 enables targeted DNA editing through guide RNA-directed Cas9 nuclease activity, allowing gene modification, mutation correction, and disease mechanism analysis. This has opened new avenues in personalized medicine and gene therapy, particularly for cancer and inherited disorders, alongside applications in agriculture. In oncology, CRISPR-Cas9 demonstrates strong potential in oncogene targeting, immune cell engineering, and CAR-T-based immunotherapy, supported by substantial preclinical success. Delivery efficiency is enhanced through systems such as exosomes, liposomes, and nanoparticles, improving stability and tumor targeting. However, clinical translation remains constrained by off-target effects, delivery limitations, and ethical concerns in human genome editing, particularly germline modification. CRISPR shows therapeutic promise for muscular dystrophy, sickle cell disease, and cystic fibrosis. Emerging platforms including base editing, prime editing, and dCas9-based epigenome editing enable precise genome and gene regulation without double-strand breaks, reducing toxicity and expanding therapeutic scope in cancer and genetic diseases. Regulatory frameworks remain heterogeneous, affecting translation. The United States leads in approvals and clinical progress, the European Union emphasizes safety and ethics, China shows rapid expansion in clinical trials, and India remains in early stages due to regulatory and infrastructure constraints. Public perception influences adoption, shaped by misinformation and limited awareness. Persistent gaps in long-term safety, clinical efficacy, and population diversity remain challenges. Overall, CRISPR-Cas9 represents a transformative but carefully regulated platform for advancing biotechnology and medicine.\n\nID: 42176253\nTitle: A feeder-free culture system supports long-term expansion and germline competence of bovine formative embryonic stem cells\u2020.\nAbstract: Bovine embryonic stem cells (bESCs) are a cornerstone for next-generation applications such as cell-cultured meat, large-animal gene editing, and embryo-stem cell breeding systems. Although primed bESCs and bovine expanded potential stem cells have recently been established, their routine maintenance commonly relies on mouse embryonic fibroblast or bovine fetal fibroblast feeder layers, which are complex, labor-intensive, poorly standardized, and incompatible with scalable manufacturing. Here, we report a simplified feeder-free culture platform for bESCs in which a commercially available basal medium is combined with Growth Factor Reduced Matrigel to generate a three-dimensional, niche-mimetic substrate. Using this approach, we successfully derived a novel feeder-free bESCs (FF-bESCs) that can be robustly expanded for more than 60 passages without ROCK inhibitors, while maintaining a normal karyotype, high proliferation rates, and stable expression of core pluripotency markers. Functional assays confirmed that FF-bESCs possess bona fide pluripotency, as evidenced by their ability to form embryoid bodies in vitro and generate teratomas containing derivatives of all three germ layers in vivo. Transcriptomic profiling further revealed that FF-bESCs align with a formative pluripotent state. Notably, these cells can be directed to differentiate into primordial germ cell-like cells. Our feeder-free culture system provides a scalable, reproducible foundation for advancing bESC-based technologies in bovine precision genome editing and germ cell differentiation for embryo-stem cell breeding systems.\n\nID: 42100918\nTitle: Functional characterization of the 9q34.13 locus identifies RAPGEF1 as modulating risk for melanoma and nevi via RAS activation.\nAbstract: Genome-wide association studies identified a melanoma- and nevus count-associated locus on chromosome band 9q34.13. Fine-mapping and melanocyte expression data collectively suggest two potential causal genes with opposite association with risk: higher levels of Rap guanine nucleotide exchange factor 1 (RAPGEF1) and lower levels of uridine-cytidine kinase 1 (UCK1). Colocalization analyses and conditional TWAS suggest multiple causal cis-regulatory sequence variants in partial linkage disequilibrium (LD) to each other. Melanocyte capture-HiC and CRISPR-inhibition demonstrated regulatory interactions between fine-mapped variants and the RAPGEF1 and UCK1 promoters. Focusing on RAPGEF1, we demonstrate RAPGEF1 expression promotes melanocyte growth and drives malignant transformation of human immortalized melanocytes. Following treatment with human EGF, RAPGEF1 overexpression activated both RAP1 and RAS. Further, we show RAPGEF1 expression is significantly enriched in melanomas lacking strongly activating RAS-MAPK mutations, suggesting that RAPGEF1 may promote oncogenic RAS-MAPK signaling in melanomas. Furthermore, in these tumors, we provide preliminary evidence to support the prognostic relevance of RAPGEF1 expression in patients lacking RAS or BRAF mutations. Together with other recent studies, these data suggest that germline variation influencing RAS activation may play a key role in nevus development and melanoma risk.\n\nID: 42074014\nTitle: CRISPR Applications in Alzheimer's Disease: From High-Throughput Genetic Screening to Precision Editing and CNS Delivery.\nAbstract: Alzheimer's disease is a devastating progressive neurodegenerative disorder characterized by extracellular amyloid-beta plaques and intracellular tau tangles. Despite recent advancements in amyloid-beta-targeting immunotherapies, achieving safe and definitive disease control remains a profound clinical challenge. The CRISPR/Cas9 system has emerged as a powerful technology for precision neurogenetics, offering significant potential to address the fundamental questions behind Alzheimer's disease. This comprehensive review delineates the trajectory of CRISPR applications in Alzheimer's disease research and therapeutics. First, we explore the integration of CRISPR in engineering high-fidelity in vitro models, such as isogenic induced pluripotent stem cells and three-dimensional cerebral organoids, alongside advanced in vivo mammalian models. Second, we examine how these platforms facilitate unbiased high-throughput genetic screening to uncover molecular underpinnings regulating tau, lipid metabolism, and neuroinflammation. Third, we critically evaluate precision editing strategies targeting core risk genes (APP, MAPT, APOE, and TREM2), explicitly highlighting the severe physiopathological trade-offs between therapeutic efficacy and loss-of-function toxicity. Finally, we address the ultimate translational bottlenecks impeding clinical application. By dissecting the packaging limits of adeno-associated viral vectors and the physical barricade of the blood-brain barrier, we underscore the necessity of transitioning toward next-generation base editors and non-viral lipid nanoparticles to realize safe and efficacious in vivo clinical gene therapies against Alzheimer's disease.\n\nID: 42066834\nTitle: Mechanistic insights into gene regulation driving normal and malignant hematopoietic development from embryonic and induced pluripotent stem cell differentiation.\nAbstract: The hematopoietic system originates from mesodermal cells of the vertebrate embryo, giving rise to pluripotent hematopoietic stem cells (HSCs) from which all mature blood cell types originate for the entire lifespan of the organism. Due to the multitude of diseases of the blood system, such as leukemia and bone marrow failure, it is of utmost importance to understand what regulates the initial formation of this system in the embryo and subsequent cell fate decisions occurring during the development of the different mature blood cell lineages. Research along these lines has been greatly facilitated by the development of embryonic stem cell (ESC) and induced pluripotent stem cell (iPSC)-based methods. Such cells can be genetically altered and produce ample cell numbers, thus being the ideal model to elucidate how our genome controls cell fate decisions. In this review, I summarize work from my laboratory and that of others to highlight how ESC and iPSC-based systems have been used to obtain global information, enhancing our understanding of the genetic basis of hematopoiesis, how specific transcription factors interact with chromatin components to regulate differential gene expression, and how signaling molecules and growth factors modulate this process. I outline how such information can be used to optimize in vitro differentiation into specific cell types for regenerative medicine purposes. Last, but not least, I describe how in vitro systems can inform us about how blood cell development goes astray during disease processes.\n\nID: 42006372\nTitle: Artificial intelligence-driven high-content imaging decodes for NLRP7-mutant recurrent hydatidiform moles.\nAbstract: Recurrent hydatidiform moles (RHMs) are a gestational disorder primarily caused by maternal-effect loss-of-function mutations in NLRP7. This study established an in vitro model of NLRP7 mutation using patient-derived induced pluripotent stem cells (iPSCs) and integrated high-content imaging (HCI) with artificial intelligence (AI) to dissect mutation-induced multi-organellar dysfunction. Multiparametric HCI enabled synchronous capture of cellular and subcellular phenotypes, including mitochondrial function and lysosomal distribution. We developed a bio-inspired AI framework (BioVision-Segmentation) that combines a hybrid Transformer-Voronoi architecture for segmentation with mutual information analysis to quantify organelle interactions. Our findings reveal that NLRP7 mutations disrupt the lysosome-mitochondria crosstalk hub, leading to energy metabolism dysregulation, reactive oxygen species (ROS) accumulation, and organelle spatial distribution defects. Furthermore, transcriptome sequencing corroborated these findings. This study elucidates the organellar pathogenesis of RHMs and provides a technological platform for exploring therapeutic targets, facilitating a shift toward early embryo protection strategies.\n\nID: 41966789\nTitle: Ligand-based directed differentiation to produce granulosa-like cells expressing steroidogenic enzyme genes.\nAbstract: The ovarian granulosa cells are responsible for producing hormones and supporting oocytes through maturation and meiotic resumption. There is a need to generate granulosa-like cells (GLCs) from human induced pluripotent stem cells (hiPSCs) to better model human gonadal development and to test the effects of exogenous or pharmaceutical compounds on the ovary. Here we report a rapid ligand-based protocol for differentiating hiPSCs into cells that express markers of the transient developmental lineages and steroidogenic pathway genes. Single-cell RNA-sequencing (scRNA-seq) analysis identified canonical granulosa cell genes were expressed in a subset of cells and identified new genes of interest that were significantly associated with computationally modeled pseudotime. HSD17B1 was expressed in resulting GLCs but at low levels, suggesting an immature granulosa cell phenotype. The GLCs were produced using a simple culture method that could be augmented for granulosa cell functions such as sustaining oocyte growth. Producing GLCs through protocols such as this one is a first step toward designing large-scale ovarian endocrinology assays and developing personalized cell-based fertility and hormone restoration technologies in the future. This rapid protocol produced cells that express steroidogenic enzyme genes etoc blurb. Kubo and colleagues present a 5-day rapid protocol to generate immature granulosa-like cells from hiPSCs. Cells differentiated with inhibition of DKK1, a WNT signaling target gene, expressed gonadal ridge markers and FOXL2 transcripts and protein. Additionally, steroidogenic enzyme genes were expressed. A small population of differentiated cells were identified as expressing early-stage granulosa cell genes by single-cell RNA-seq.\n\nID: 41961835\nTitle: Exosomes in oncofertility: emerging roles in chemotherapy-induced reproductive damage and fertility preservation.\nAbstract: Oncofertility has emerged as a critical interdisciplinary field addressing the reproductive challenges faced by cancer patients, particularly those undergoing chemotherapy. While chemotherapeutic agents remain indispensable in cancer therapy, their gonadotoxic effects frequently result in diminished ovarian reserve, impaired spermatogenesis, and long-term infertility. Exosomes - small extracellular vesicles enriched with nucleic acids, proteins, and lipids - are increasingly recognized as key mediators of intercellular communication in both pathological and regenerative contexts. Recent evidence suggests that chemotherapy alters exosome cargo, thereby amplifying cellular stress responses, oxidative damage, and bystander effects in gonadal tissues. Conversely, exosomes derived from mesenchymal stem cells, induced pluripotent stem cells (iPSCs), and other regenerative sources demonstrate the ability to restore ovarian and testicular function by reducing apoptosis, enhancing angiogenesis, and supporting germ cell survival. This dual role positions exosomes as both contributors to reproductive toxicity and promising therapeutic agents in fertility preservation strategies. However, clinical translation remains hindered by challenges including source heterogeneity, isolation methods, safety concerns, and regulatory barriers. This review highlights the emerging roles of exosomes in chemotherapy-induced reproductive damage, explores their regenerative potential, and outlines future directions for their integration into oncofertility practice. Cancer treatments such as chemotherapy save lives, but they often damage the ovaries and testes. This can lead to infertility in both women and men, which is one of the most difficult problems for cancer survivors. Finding ways to protect or restore fertility is, therefore, an important part of cancer care. Our work looks at very small particles called exosomes. These are natural messengers that carry proteins and genetic material between cells. We explain how chemotherapy changes these exosomes in a way that increases damage to reproductive organs. At the same time, we show that exosomes from stem cells may help repair this damage. In laboratory studies, they have been shown to protect eggs and sperm and reduce cell death of the reproductive organs during chemotherapy. Exosomes can also act as simple blood-based tests to detect damage and monitor recovery. This research is important because it points to new, less invasive ways to protect fertility during and after cancer treatment. If successful, exosome-based therapies could give patients not only a chance of survival but also the hope of having children in the future.\n\nID: 41920273\nTitle: Experimental Models to Study Polyglutamine Spinocerebellar Ataxias: From Mechanisms to Therapeutic Developments.\nAbstract: Spinocerebellar ataxias (SCAs) are a large and heterogeneous group of inherent neurodegenerative diseases. A select group of SCAs are caused by abnormal CAG repeat expansions within the coding region of specific genes (polyQ SCAs). These alterations result in the synthesis of mutant proteins that carry an expanded tract of glutamine residues, which confers on them a toxic gain-of-function that disrupts multiple cellular processes, ultimately resulting in selective neuronal death. PolyQ SCAs are characterized by a core set of clinical features, including progressive cerebellar ataxia, motor incoordination, and neurodegeneration affecting the cerebellum and related neural circuits. At the molecular level, polyQ tracts have been shown to promote protein misfolding and aggregation, which in turn leads to cellular toxicity. Each SCA exhibits a distinctive pattern of cellular vulnerability, clinical progression, and neuropathology; therefore, the development of experimental models has been pivotal in elucidating disease mechanisms and facilitating translational research. In this review, we summarize the main experimental models utilized to study polyQ SCAs. These models include: (1) cellular systems that allow rapid and controlled analysis of molecular toxicity; (2) patient-derived induced pluripotent stem cells, which preserve endogenous gene regulation and genetic backgrounds; (3) non-mammalian organisms such as Drosophila melanogaster, Caenorhabditis elegans, and zebrafish, which support genetic screening and medium-throughput studies; (4) murine models that reproduce in vivo motor deficits, cerebellar degeneration, and transcriptional alterations; and (5) non-human primates (NHPs), which closely resemble human brain structure and function. We discuss the strengths and limitations of each model and underscore their contributions to elucidating the pathophysiology of disease and promoting the development of molecular therapies for polyQ SCAs.\n\nID: 41846085\nTitle: Oxidative homeostasis and survival instincts of chicken egg, embryo and adult.\nAbstract: Chicken embryos and stem cells require precisely regulated levels of reactive oxygen species (ROS) to maintain self-renewal and pluripotency. However, excessive ROS induces oxidative stress, leading to DNA damage, chromosomal aberrations, loss of mitochondrial membrane potential, and ultimately, abnormal differentiation or cell death. This oxidative imbalance is a significant barrier to successful embryonic development and the in vitro culture of stem cells. Innate antioxidant defense systems exist within chicken and mammalian embryos to scavenge excess ROS, a finding that has prompted the strategic addition of antioxidants to culture media. The present review has two primary foci. Firstly, it seeks to expand the understanding of the antioxidant defense mechanisms of the chicken embryo. Secondly, it explores the role of exogenous antioxidant supplementation in the culture of various stem cell types, including embryonic stem cells (ESCs), primordial germ cells (PGCs), spermatogonial stem cells (SSCs), and induced pluripotent stem cells (iPSCs). Enhancing in vitro stem cell survival and directed differentiation through antioxidant supplementation holds significant promise for advancing fields such as tissue regeneration, organ transplantation, and the development of transgenic chicken models for improved production traits, vaccine development, and recombinant protein production.\n\nID: 41757835\nTitle: In vitro maturation 2.0: a new era for an underdog in ART.\nAbstract: In vitro maturation (IVM) of human oocytes, once a pioneering concept predating conventional IVF, has long remained an underutilized technique in assisted reproduction. Despite early promise, clinical adoption of IVM has been limited due to lower embryo developmental competence and live birth rates compared to IVF. However, recent advances in the understanding of oocyte physiology, including cumulus-oocyte communication, the regulatory roles of cAMP/cGMP signaling pathways, and endocrine modulation of meiotic resumption, have reignited interest in optimizing IVM protocols. Innovations such as biphasic Capacitation (CAPA) IVM systems and the use of ovarian somatic support cells (OSCs) derived from induced pluripotent stem cells (iPSCs) aim to replicate the dynamic follicular environment more accurately and enhance oocyte competence. Clinical studies suggest that, while IVM still results in modestly lower cumulative live birth rates compared to conventional IVF, it offers significant advantages for selected patient populations, particularly women with polycystic ovary syndrome (PCOS), high ovarian reserve, or those requiring fertility preservation. Importantly, current evidence supports the genetic and epigenetic safety of IVM-derived offspring. As technical refinements continue and professional education expands, IVM is poised to fulfill its potential as a safer, less invasive, and more accessible alternative within the landscape of assisted reproductive technologies.\n\nID: 41717698\nTitle: Ablation of PKC\u03b1 Phosphorylation by CRISPR-Cas9 Base Editing Rescues Heart Failure.\nAbstract: The prevalence of heart failure is increasing globally, with poor prognosis, highlighting the need for novel therapeutic strategies. PKC\u03b1 (protein kinase C alpha), encoded by PRKCA, plays a central role in heart failure pathogenesis. Phosphorylation of PKC\u03b1 at threonine 497 (T497) triggers a series of intramolecular phosphorylation events, leading to its activation. Ablation of T497 phosphorylation leads to reduced stability and activity of PKC\u03b1. We generated mice harboring a phospho-resistant PKC\u03b1 (T497A) mutation in the germline using CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats/clustered regularly interspaced short palindromic repeat-associated 9)-mediated homology-directed repair. To assess the clinical feasibility of postnatal genome editing, we used CRISPR-Cas9 adenine base editing delivered by adeno-associated virus 9 to introduce the T497A substitution into the Prkca gene (PrkcaT497A) in wild-type mice. Mice underwent transverse aortic constriction to model heart failure. Cardiac function, hypertrophy, fibrosis, and transcriptional changes were evaluated by echocardiography, wheat germ agglutinin staining, Masson's trichrome staining, and RNA-sequencing. The editing efficiency of PrkcaT497A was assessed using Sanger sequencing and deep amplicon sequencing. To further explore its clinical potential, we introduced the PRKCAT497A mutation into human induced pluripotent stem cells by nucleofection-mediated adenine base editing. Ca2+ homeostasis was analyzed in Fura-2-loaded human induced pluripotent stem cell-derived cardiomyocytes with PRKCAT497A under chronic AngII (angiotensin II) stimulation. The T497A mutation in PKC\u03b1 prevented its subsequent phosphorylation and led to PKC\u03b1 protein degradation. Four weeks after transverse aortic constriction surgery, wild-type mice showed impaired cardiac function, cardiac remodeling, and increased lung weight. In contrast, PKC\u03b1 phospho-resistant mice showed protection against heart failure-related aberrant changes in cardiac hypertrophy, fibrosis, and cardiac gene expression. Mice administered with adeno-associated virus 9 base editors to prevent T497 phosphorylation exhibited similar cardioprotective effects. In vitro, PKC\u03b1-edited induced pluripotent stem cell-derived cardiomyocytes were protected from AngII-induced impairments in contractility and Ca2+ transients. The editing of PRKCAT497A through adenine base editing represents a potential therapeutic approach for human cardiac diseases.\n\nID: 41716912\nTitle: An induced pluripotent stem cell-based chemical genetic approach for studying spinal muscular atrophy.\nAbstract: Spinal muscular atrophy (SMA) is a genetic disease characterized by degeneration of spinal cord motor neurons and neuromuscular junctions. Despite recent developments in therapies for SMA, treatment efficacy largely relies on the administration of drugs early in disease progression and is impacted by underlying patient genetics. Drug discovery for other diseases of the central nervous system (CNS) has also been hindered by heterogeneity in patient genetics and clinical presentations, as well as the need for early intervention. To address these hurdles, we utilized a chemical-genetic-based screening approach to adapt the Connectivity Map (CMAP)/L1000 platform to study SMA. To do this, we differentiated moderate and severe SMA patient-specific induced pluripotent stem cells into neuronal cells utilizing a forward programming differentiation protocol, exposed each to 360 neuroactive or CNS disease-related compounds, and interrogated resulting changes in expression of >400 neural genes in a platform we term CMAPneuro. In doing so, we generated 4,559 transcriptional profiles identifying stimuli that modulate gene expression differences across SMA neurons. Finally, we make these data queryable, allowing the research community to (1) identify CNS disease-related perturbagens that mimic or reverse differentially expressed genes, or (2) explore the transcriptional response of a given perturbation in diverse SMA neuronal cells. Taken together, CMAPneuro represents a novel tool to identify candidate stimuli for follow-up investigation into the biology of SMA and related disorders.\n\nID: 41650934\nTitle: Nurturing eggs with hiPSC-derived cells to improve outcomes in in vitro fertilization.\nAbstract: Clinical success of in vitro maturation (IVM) for fertility treatment is currently limited by the lack of a reliable source of ovarian support cells (OSCs) to nurture oocytes. Kramme et al. develop \"Fertilo,\" a scalable, clinical-grade hiPSC-derived OSC product that significantly enhances oocyte maturation and improves clinical reproductive outcomes.1.\n\nID: 41581067\nTitle: Bioethics in assisted reproduction and embryology.\nAbstract: The use of assisted reproductive therapies, advances in embryo research, and developments in scientific fields such as gene editing and in vitro gametogenesis have attracted the attention of bioethicists for years. On one side, the 14-day rule has faced criticism from embryo researchers advocating for its extension. On the other side, the increasing number of cryopreserved embryos worldwide has raised practical and ethical concerns about their fate. While advancements in scientific research, especially gene editing and in-vitro gametogenesis (IVG), are not yet fully applicable, their potential future use appears to pose significant bioethical questions. In this review, we examine the evolving bioethics of embryo research, focusing on the 14-day rule, the challenges surrounding surplus cryopreserved embryos, and the future dilemmas posed by CRISPR-based gene editing, IVG, and preimplantation genetic testing for polygenic risk (PGT-P). We also highlight the critical role of multidisciplinary, patient-centered counseling in ART practice, to foster informed consent, realistic expectations, and psychosocial well-being. Finally, we underscore the need for anticipatory ethical frameworks and open-society engagement that integrate public deliberation with scientific progress to ensure that reproductive innovation proceeds responsibly, preserving both human dignity and social justice.\n\nID: 41574959\nTitle: Autosomal Dominant Erythrocytosis Caused by Non-Renal Erythropoietin (EPO) Due to EPO c.-136 G>A Germline Mutation.\nAbstract: We previously reported a five-generation kindred with autosomal dominant erythrocytosis associated with a novel germline promoter variant in the erythropoietin (EPO) gene (EPO c.-136\u2009G>A). This mutation creates a new hypoxia response element (HRE) consensus sequence on the reverse strand suggesting a gain of function mutation. CRISPR/Cas9-edited Hep3B cells harboring the c.-136\u2009G>A variant had increased EPO mRNA and protein expression under both normoxic and hypoxic conditions compared to wild-type cells; functional assays confirmed the activity of the c.-136\u2009G>A variant-induced EPO. Isoelectric focusing analyses of patient urine and plasma showed a more basic EPO isoform pattern, consistent with the reduced sulfated N-glycan contribution, suggesting decreased renal and increased non-renal expression. Luciferase reporter assays confirmed increased transcriptional activation of the mutant promoter. However, chromatin immunoprecipitation did not verify direct hypoxia-inducible factor (HIF)-1/2 binding, suggesting the possible involvement of alternative regulatory elements. These findings support a model in which the EPO c.-136\u2009G>A promoter variant introduces a new HRE that overrides the normal kidney expression resulting in persistent or ectopic non-renal EPO production postnatally. This study expands the spectrum of molecular mechanisms underlying hereditary erythrocytosis and provides novel mechanistic insights into EPO regulation, including its tissue-specific expression.\n\nID: 41534521\nTitle: Development of human induced pluripotent stem cell-derived ovarian support cells as a clinical-grade product for in vitro fertilization.\nAbstract: Human induced pluripotent stem cells (hiPSCs) show promise in the development of novel strategies to alleviate reproductive diseases and improve reproductive outcomes. Here, we detail the clinical development and application of an ovarian support cell (OSC) product, Fertilo, to improve the in vitro maturation (IVM) of human oocytes. First, we demonstrate that transcription factor-mediated hiPSC differentiation produces OSCs that improve the oocyte MII maturation rate. To support clinical application, we describe raw material upgrades and the generation of clinically suitable hiPSC seed and master cell banks, with transcriptomic analysis of resultant OSCs showing consistent and reproducible outcomes. Next, we detail analytical release testing and development of a murine oocyte maturation assay to assess product potency. Finally, application of Fertilo in a longitudinal cohort analysis shows improvement in key outcomes, compared with traditional IVM. Our findings demonstrate the first-time clinical development and application of an hiPSC-derived product to promote successful reproductive outcomes.\n\nID: 41483428\nTitle: TNFRSF13B Variant-Induced TACI Dysregulation Underlies CAEBV Pathogenesis.\nAbstract: The tumor necrosis factor (TNF) receptor superfamily member, transmembrane activator and CAML interactor (TACI) encoded by TNFRSF13B, are extensively involved in immune responses. In our previous work, TNFRSF13B exon 2 variants were recurrently identified in chronic active Epstein-Barr virus disease (CAEBV). Here we aim to reveal the roles of TNFRSF13B variants in CAEBV, and investigate the feasibility of targeting TNFRSF13B/TACI as a new approach to control EBV infection. The lymphoblastoid cell lines (LCL) models carrying homozygous TNFRSF13B exon 2 frameshift mutations were constructed using CRISPR/Cas9. Immunological assays, transcriptomic analysis, and gene silencing experiments were performed on LCL models to measure the effect of TNFRSF13B exon 2 variants and explore the underlying mechanisms. TACI ligands and a TLR9 agonist were applied to modulate TACI signaling and EBV activities. Frameshift mutations in exon 2 of TNFRSF13B significantly up-regulated the short isoforms of TACI (TACI-S) at the expense of its long isoforms (TACI-L) in LCLs. The up-regulated TACI-S induced more intense activation of NF-\u03baB, MAPK, and Rho signaling pathways, leading to the switch of EBV activities to lytic reactivation. The subsequent increased viral load and viral IL-10 provide a rational for the susceptibility of variant carriers to CAEBV. The BAFF trimer, an indirect TACI-signaling inhibitor, also significantly suppressed the EBV lytic program. Gene silencing experiments indicated that XBP-1 might be involved in the TACI-mediated regulation of EBV lytic activities in EBV-immortalized B cells. This study underscores the impact of TNFRSF13B variants on EBV infection and host immune responses, offering insights into CAEBV pathogenesis and potential therapeutic strategies.\n\nID: 41462929\nTitle: Atrazine Induces Reproductive Toxicity in an In Vitro Spermatogenesis (IVS) Model.\nAbstract: Background/Objectives: Atrazine (ATZ) is a widely used herbicide, and most studies of its reproductive toxicity have been conducted in vivo using animal models, where ATZ disrupts redox homeostasis, leading to male reproductive dysfunction. However, its molecular mechanisms of action in human spermatogenic cells remain poorly understood. Huntington's disease (HD), an autosomal dominant disorder caused by abnormal CAG repeat expansion in the HTT gene, exhibits heightened oxidative stress sensitivity and mitochondrial dysfunction, which may further impair reproductive function. This study investigated ATZ effects on human spermatogenesis using an in vitro spermatogenesis (IVS) model derived from human induced pluripotent stem cells (hiPSCs), focusing on Nrf2-mediated oxidative responses and apoptotic regulation during spermatogonial stem cell-like cell (SSCLC) differentiation in wild-type (WT) and HD hiPSC lines. Methods: Two WT and two HD hiPSC lines carrying 44 (HD1) and 180 (HD2) CAG repeats were treated with ATZ (0, 0.01, 1, or 10 \u03bcM) for 30 days, followed by differentiation into SSCLCs for 15 days under continuous exposure. Expression of pluripotency (OCT4, SOX2), oxidative stress (NFE2L2, SOD1, GPX1, NQO1), cell cycle (CDK1), apoptosis (BCL2, BAX, CASP3, CASP9, FAS, FASLG), and spermatogenic markers (DAZL, ZBTB16, GFRA1, PIWIL2) were assessed by immunocytochemistry and qRT-PCR. Results: Long-term ATZ exposure affected pluripotency markers in hiPSCs and SSCLC differentiation in a cell line-dependent manner. WT cells exhibited early differentiation suppression without significant apoptosis. HD1 cells were highly sensitive: low ATZ doses (0.01-1 \u03bcM) partially activated intrinsic and extrinsic apoptotic pathways, whereas high-dose ATZ (10 \u03bcM) reduced Nrf2-target and spermatogenic gene expression, strongly impairing SSCLC maturation. HD2 cells showed pronounced oxidative stress with robust Nrf2-driven antioxidant responses and BCL2 that supported differentiation at low doses. However, excessive oxidative or proliferative signaling, including CDK1 upregulation at high ATZ concentrations, disrupted redox balance and SSCLC differentiation in HD2 cells. Conclusions: ATZ exerts dose- and genotype-dependent effects on IVS through coordinated regulation of oxidative stress and apoptosis. These findings highlight the interplay between Nrf2-mediated antioxidant defenses, apoptotic signaling, and genetic background in shaping spermatogenic outcomes, providing mechanistic insight into ATZ-induced reproductive toxicity in a human-relevant in vitro spermatogenesis model.\n\nID: 41419637\nTitle: CRISPR screens in human neural organoids and assembloids.\nAbstract: Studying the molecular mechanisms underlying the assembly of the human nervous system remains a significant challenge. The ability to generate neural cells from pluripotent stem cells, combined with advanced genome-editing techniques, provides unprecedented opportunities to uncover the biology of human neurodevelopment and disease. Organoids and assembloids enable the in vitro modeling of previously inaccessible developmental processes, such as the specification and migration of human neurons, including the integration of cortical interneurons from the ventral into the dorsal forebrain. Here, we present a detailed protocol that combines pooled CRISPR-Cas9 screening with neural organoid and assembloid models and illustrate how it can be applied to map hundreds of disease genes onto cellular pathways and specific aspects of human neural development. Our protocol outlines key steps, from planning and optimizing genetic perturbations to designing readouts for neuronal generation and migration, conducting the screening and validating candidate genes. The screening experiments take ~3 months to complete and require expertise in stem cell culture and neural differentiation, genetic engineering of human induced pluripotent stem cell lines, fluorescence-activated cell sorting and next-generation sequencing and analyses. The integration of genetic screening and human cellular models constitutes a powerful platform for investigating the mechanisms of human brain development and disease, paving the way for the discovery of novel therapeutics.\n\nID: 42630992\nTitle: Regulating human reproductive and developmental biotechnologies: a UK reference model.\nAbstract: Rapid scientific change is exposing the limits of the UK's regulation of human reproductive and developmental biology. Embryo-like structures, in vitro gametogenesis, organoids and heritable genome editing advance understanding of human development and physiology and support new applications in assisted reproduction and clinical care, yet the current regulatory framework is ill-equipped to govern them coherently. A case is made for coordinated, technology-neutral regulatory change. The article proposes the principles of a model UK Human Reproductive and Developmental Biotechnology Act and regulator, the Human Reproductive and Developmental Biotechnology Authority-or HRBA, pronounced 'harbor'-to provide a permissions route across research and translation. The model Act is a modular, risk-tiered scheme with consistent standards and tailored red lines. It is designed to accommodate boundary cases, to integrate and build upon the existing remit of the Human Fertilisation and Embryology Authority, and coordinate with other established regulators to retain institutional expertise and avoid unnecessary duplication. The proposal is ambitious and would help give effect to UK Government commitments to safely advance the life sciences in this area. But even if piecemeal amendments are ultimately favored, it clarifies the underlying choices and trade-offs and provides a benchmark against which changes can be tested.\n\nID: 42628215\nTitle: Evaluation of germline transmission of electroporation-mediated double gene-edited cattle lines.\nAbstract: Gene editing in livestock using clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) offers a promising approach for genetic improvement in cattle. This study evaluated germline transmission and mutation stability of double-knockout cattle generated by zygote electroporation. Previously reported myostatin/beta-lactoglobulin (MSTN/BLG) and newly generated \u03b1-1,3-galactosyltransferase (GGTA1/BLG) double-knockout cattle were produced using CRISPR/Cas9-mediated genome editing. Targeted deep sequencing demonstrated extensive somatic mosaicism across multiple tissues. Computer-assisted sperm analysis (CASA) demonstrated normal sperm motility in MSTN/BLG double-knockout males. Fertilization of wild-type oocytes produced heterozygous embryos, with mutation frequencies of 37.76\u202f\u00b1\u202f10.74% at the MSTN locus and 54.80\u202f\u00b1\u202f7.73% at the BLG locus, as assessed by T7 endonuclease I (T7E1) assay. MSTN/BLG double-knockout sperm were subsequently used for embryo production and for artificial insemination of GGTA1/BLG double-knockout females. Healthy offspring were successfully obtained (n\u202f=\u202f3), alongside one stillborn calf. Targeted deep sequencing of all four progenies revealed highly variable allele frequencies that deviated substantially from the approximately 50% expected for heterozygous germline transmission. In contrast, whole-genome sequencing (WGS) results were consistent with Mendelian expectations, underscoring the limitations of PCR-based targeted sequencing for assessing germline transmission in mosaic founders. These results show that CRISPR/Cas9-edited embryos generated by electroporation can develop into healthy, sexually mature cattle capable of germline transmission. While variable transmission rates were observed owing to founder mosaicism, non-mosaic F1 offspring were successfully generated. However, direct, embryo-mediated gene-editing strategies remain technically and economically challenging for large-scale commercial calf production, and reports in cattle are limited. This study provides a reference for future applications of gene-edited embryos and their germline propagation.\n\nID: 42625507\nTitle: Porcine Expanded Potential Stem Cells as a Versatile Platform for Multiplex Genome Editing and Immunophenotyping in Xenotransplantation.\nAbstract: Xenotransplantation utilizing pig donors offers a promising solution to organ shortages, but immune incompatibilities across species remain a major challenge. Current reliance on porcine primary fibroblasts for genome editing is limited by low inefficiency in complex gene editing and difficulties in immunophenotyping edited cells. In this study, we demonstrate that porcine expanded potential stem cells (pEPSCs), derived from preimplantation embryos, provide a robust and versatile platform for generating donor cells for xenotransplantation. These pluripotent cells can differentiate into both embryonic and extraembryonic lineages, maintain genetic stability through multiple edits, and enable precise genome modifications. We performed multiple gene knockouts in pEPSCs targeting key immune rejection genes and precisely inserted a genetic cassette to facilitate streamlined introduction of human cDNAs via cassette exchange. The engineered pEPSCs retained their pluripotency and stability even after multiple rounds of genome editing. When differentiated into endothelial cells, they exhibited high immunogenicity, serving as a rapid and quantitative platform for immune response assessment. Importantly, the edited endothelial cells exhibited substantially reduced immunogenicity, confirming the functional impact of the genetic modifications. Although we have not yet generated live pigs from these gene-edited pEPSCs via somatic cell nuclear transfer (SCNT), our findings establish pEPSCs as a novel and improved platform for generating genetically engineered pig donors and for functionally evaluating genetic modifications, thereby advancing the prospects of xenotransplantation.\n\nID: 42617141\nTitle: Translating CRISPR to Practice in the Clinic: Transformative Therapy in Hemoglobinopathies and Emerging Applications in Malignancies.\nAbstract: Exagamglogene autotemcel, the first clustered regularly interspaced short palindromic repeats (CRISPR)-based gene-editing therapy to enter clinical practice, has established genome editing as a curative-intent option for eligible patients with severe sickle cell disease (SCD) and transfusion-dependent \u03b2-thalassemia (TDT). Ex vivo CRISPR-Cas9 editing of autologous CD34-positive hematopoietic stem and progenitor cells to reactivate fetal hemoglobin has produced durable freedom from severe vaso-occlusive crises in SCD and sustained transfusion independence in TDT. This approach offers a donor-independent alternative to allogeneic hematopoietic stem-cell transplantation without graft rejection or graft-versus-host disease. Hemoglobinopathies, therefore, provide the first clinically validated delivery model for CRISPR therapeutics. Successful implementation, however, requires more than editing efficacy. It depends on structured referral, candidacy assessment, organ function review, mobilization and collection, centralized manufacturing, pharmacokinetic-guided myeloablative conditioning, transplant-level supportive care, fertility preservation, psychosocial support, and prolonged surveillance coordinated among primary hematologists and cellular therapy programs. Key barriers include stem cell collection, conditioning-related toxicity, cost, reimbursement friction, and persistent inequities in access. Long-term follow-up and registry participation are necessary to evaluate outcomes beyond pain crises, identify late toxic effects, and compare real-world effectiveness across gene editing, gene addition, and allogeneic transplantation. In oncology, CRISPR-based therapy remains investigational, with early clinical feasibility demonstrated in relapsed or refractory B-cell malignancies, T-cell malignancies, AML, multiple myeloma, and selected solid tumors. For hematologists, oncologists, and transplant and cellular therapy programs, the central challenge is to integrate CRISPR into practice with the rigor required for any high-risk curative therapy: careful patient selection, disciplined delivery, and long-term accountability.\n\nID: 42613624\nTitle: Stem cell-based therapies in pediatric disorders: translational advances, unresolved challenges, and future horizons.\nAbstract: Pediatric disorders consist of genetic, hematologic, neurologic, autoimmune, and inflammatory diseases. These conditions impose long-term health challenges on children, despite many advancements with conventional medicine. Although conventional treatments increase life expectancy and provide better disease control, many present challenges such as toxicity, insufficient control of the disease, and adverse effects on normal growth, development, and quality of life. Many researchers have shown increased interest in using stem cell therapies as an alternative to current medications to allow for complete, sustainable repair of damaged tissues and modification of disease processes (i.e., using stem cells to regenerate tissue or change the way in which a disease occurs). This paper will provide the current information on stem cells used in the treatment of children and the many different types of stem cells, including: hematopoietic stem cells (and their derivatives), mesenchymal stem cells (and their derivatives), induced pluripotent stem cells, embryonic stem cells, tissue-specific progenitor cells, extracellular vesicles, and bioengineered products. This paper will also discuss what is known about the stem cells listed as well as their methods of action, where they might currently be better utilized, and future uses of these cells in children for a variety of types of pediatric diseases. Because each stem cell type listed has very different scientific background and clinical evidence, there is much variability in the amount of scientific evidence available to support stem cell therapies. For example, hematopoietic stem cell transplantation (HSCT) has over 50 years of clinical experience; thus, there are many studies defining the clinical efficacy and long-term outcomes associated with HSCT. Conversely, while there are many published studies supporting the use of mesenchymal stem cells (MSCs), extracellular vesicles (EVs), gene-edited cells, organoids, and many induced pluripotent stem cell-derived therapies, more evidence (clinical and basic science) is still needed to fully establish efficacy for the use of these various stem cells in children with pediatric diseases. In addition to needing more clinical evidence, stem cell-based therapies face many important challenges to the advancement of these therapies, including (but not limited to) long-term safety assessments, manufacturing standardization, regulatory oversight, ethical concerns, and equitable access to advanced therapies. Addressing these challenges will be important for future advances in the use of regenerative medicine in pediatric patients which will also require the rigorous evaluation of new stem cell therapies, the continued improvement of translational mechanisms, and the ongoing incorporation of new techniques (e.g., genome editing, organoid modeling, EV therapeutics, bioengineering, and artificial intelligence) to advance regenerative medicine and demonstrate its value through safe and reproducible clinical trial results.\n\nID: 42612243\nTitle: CRISPR-Cas9-induced genetic mosaicism in three species of the microcrustacean Daphnia.\nAbstract: Genetic mosaicism can arise from in vivo CRISPR-Cas9 gene editing, especially in the embryos. This study evaluates the extent of genetic mosaicism resulted from CRISPR-Cas9-mediated knockout for 11 genes in the freshwater microcrustacean Daphnia magna, D. pulex, and D. sinensis. Based on extensive genotyping data of the asexually produced progenies of successfully edited females, we find strong evidence of mosaicism in 9 of these genes. The genotyping data also suggest the gene editing activity can take place as early as the one-cell embryo stage and extends into the 32-cell and later stages. This study establishes genetic mosaicism as an important feature of Cas9-mediated gene editing in Daphnia.\n\nID: 42611607\nTitle: Light- and X-ray-Activated Liposomes for Controlled Gene Editing and Drug Delivery.\nAbstract: Photodynamic therapy (PDT) exploits photosensitizer activation to generate reactive oxygen species (ROS), principally singlet oxygen. Beyond direct cytotoxicity, this photochemistry can be repurposed for on-demand cargo release from lipid nanocarrier systems, enabling spatiotemporal control over therapeutic delivery that is not achievable with conventional lipid nanoparticles. This protocol presents methods for fabricating and characterising two distinct verteporfin (VP)-integrated lipid nanoparticle formulations: (1) light-triggered liposomes composed of DOTAP, DOPE, cholesterol, and VP for delivery of CRISPR-Cas9 ribonucleoprotein (RNP) complexes; and (2) X-ray-triggered liposomes composed of DOTAP, DOPC, VP, and gold nanoparticles for controlled chemotherapy drug release. Upon activation at 690 nm (visible light) or by clinical X-ray radiation (6 MeV), VP generates singlet oxygen that oxidises unsaturated lipid components, destabilising the nanoparticle membrane and releasing encapsulated cargos. Protocols are provided for liposome formulation by thin-film hydration and membrane extrusion, physicochemical characterisation, light- and X-ray-triggered cargo release assessment, in vitro gene knockout in human cells, and in vivo validation using a quantitative zebrafish visual reporter system and a mouse xenograft tumour model. Representative results demonstrate knockout of up to approximately 326 slow-muscle fibres per zebrafish embryo via light activation and significant tumour growth suppression via X-ray-triggered doxorubicin release.The clinical precedent for 689-690 nm verteporfin activation in the eye motivates evaluation of this platform for ophthalmic delivery, although retinal biodistribution, pharmacokinetics, and large-animal safety remain to be established. These methods provide an experimental approach with translational potential for externally controlled therapeutic cargo release.\n\nID: 42611132\nTitle: A novel needleless delivery of Cas9 ribonucleoprotein complex in Bemisia tabaci embryos for gene editing.\nAbstract: The CRISPR/Cas9 system, particularly the Cas9-sgRNA ribonucleoprotein (RNP) complex, offers a highly efficient platform for gene editing. However, traditional microinjection methods for RNP delivery in insect embryos are labor-intensive, technically demanding, and often reduce embryo viability, especially in species with fragile, microscopic embryos. In this study, a novel, non-invasive delivery method for the RNP complex in tiny insect embryos has been optimized. Whitefly, Bemisia tabaci, an invasive insect pest of agricultural importance and vector of plant diseases, was considered as a model organism. A needleless dechorionation-permeabilization method was employed to deliver the RNP complex to the early embryonic stage of B. tabaci embryos. B. tabaci heat shock protein 70 (hsp70) gene, which interacts with the begomovirus coat protein, aiding in its internalization and successful transmission by B. tabaci in a persistent circulative manner, was targeted for knockout. Two sgRNAs were synthesized via in vitro transcription, and the Cas9-sgRNA complexes were validated by in vitro cleavage assays. The localization of the GFP-labelled Cas9-sgRNA complex confirmed successful RNP delivery, as observed through confocal microscopy. A survival rate of 18% of the embryos was recorded post-RNP delivery. Sequencing of treated embryos showed 25- and 28-nucleotide deletions in the hsp70 exon. Synthego ICE analysis revealed up to 84% gene knockout efficiency. This method enables batch processing of embryos, drastically reducing delivery time and associated costs while improving throughput. Hsp70 KO B. tabaci mutants generated in the study are expected to be incompetent begomovirus transmitters, which would help restrict the spread of the virus. Our study overcomes a key bottleneck in CRISPR/Cas delivery to small insect embryos, opening new avenues for rapid, high-throughput, and cost-effective RNP delivery methods in insect embryos. The novel non-invasive methods would be helpful in the deployment of gene editing for sustainable pest control.\n\nID: 42608059\nTitle: The combination of morphogenic regulators BABY BOOM and GRF-GIF improves maize transformation efficiency and promotes leaf regeneration.\nAbstract: Transformation is an indispensable tool for plant genetics and functional genomics. Although stable transformation in maize is no longer a major obstacle, there remains a need for accessible and efficient methods for academic laboratories. Here, we present the GGB\u00a0system, a rapid and efficient approach optimized for immature embryo transformation in B104 and other maize lines. This system combines two distinct morphogenetic regulators, the wheat GRF4-GIF1 chimera and the maize BABY BOOM (BBM) transcription factor (hence the name \"GGB\") with a modified QuickCorn protocol, enabling regeneration of transformed maize plantlets in c. 2 months with an efficiency 7-fold higher than when compared to either morphogenic factor used in isolation. Expression of both regulators did not significantly affect development, eliminating the need to excise them after regeneration. However, transmission of the transgenic GGB construct through pollen was significantly reduced, potentially aiding transgenic line containment. We show that the GGB system is adaptable for CRISPR-Cas9 editing and reporter line generation. Furthermore, stable GGB transformants exhibited high leaf regeneration capacity via somatic embryogenesis. RNA-seq time-course profiling of GGB leaf cultures identified additional factors that could promote regeneration and led to the discovery of asparagine and trehalose as additional media components that significantly enhanced leaf regeneration.\n\nID: 42599088\nTitle: Liver Organoids: From Disease Modelling to Regenerative Medicine.\nAbstract: Liver organoids are three-dimensional miniature liver models that recapitulate the complex architecture and key functions of the human liver in\u00a0vitro, offering powerful platforms for both fundamental research and translational applications. This review systematically summarises current fabrication strategies, disease-modelling utilities and regenerative potentials of liver organoids, alongside the major challenges and future directions. In recent years, the field has witnessed several breakthroughs. Through endothelial co-culture approaches, vascularised and metabolically zonated liver organoids have been successfully generated, achieving endothelial coverage exceeding 85%. Prime editing enables precise correction of pathogenic mutations in patient-derived organoids, with no off-target effects detected at the genome-wide level. In disease modelling, iPSC-derived liver organoids faithfully recapitulate the pathological progression of metabolic dysfunction-associated steatotic liver disease (MASLD) and verify the lipid-lowering efficacy of semaglutide. Macrophage-integrated organoid models support the full life cycles of HEV, SARS-CoV-2 and dengue virus, providing new tools for antiviral drug screening. Large-scale patient-derived tumour organoid biobanks successfully preserve the heterogeneity and clinical drug-resistance signatures of liver cancers. In regenerative medicine, encapsulated hepatocyte organoids and the UTOpiA bioartificial liver system have effectively rescued acute liver failure in animal models, while gene-edited autologous organoids offer potential curative strategies for genetic disorders such as Wilson disease. Nevertheless, insufficient hepatocyte functional maturity, difficulties in constructing vascular networks, and the lack of standardised culture protocols remain major obstacles to clinical translation. By bridging fundamental liver biology and clinical practice, liver organoid technology lays a solid foundation for precision hepatology and regenerative therapies. Continued interdisciplinary efforts are still required to overcome current limitations and facilitate its clinical adoption.\n\nID: 42594811\nTitle: Pcgf5 controls the exit from totipotency in mouse embryonic stem cells.\nAbstract: Mouse embryonic stem cell (ESC) cultures contain a rare subpopulation of two-cell-like cells (2CLCs) that transiently reactivate a two-cell embryo-like transcriptional program characteristic of zygotic genome activation (ZGA), including the endogenous retrovirus MERVL and Zscan4, and thereby regain a totipotent-like state. Polycomb repressive complex 1 (PRC1)-mediated H2AK119ub1 has been implicated in restraining entry into the 2C-like state through Pcgf6, yet the factors governing exit from this state and loss of totipotency remain poorly defined. Here, we show that among the six Pcgf paralogs, Pcgf5, which is most prominently upregulated in 2CLCs and forms an MERVL-driven chimeric transcript (Pcgf5MT2C_Mm) during ZGA in 2-cell embryos, controls exit from the 2C-like state in mouse ESCs. Using a reporter ESC line carrying MERVL-tdTomato and Zscan4c-EGFP (MtZG), we manipulated Pcgf5 dosage bidirectionally. Doxycycline (Dox)-inducible overexpression (OE) of Pcgf5 reduced the double-positive (DP) 2C-like population. Conversely, CRISPR-mediated knockout (KO) of Pcgf5 by targeting a common exon shared by all Pcgf5 variants (hereafter, total Pcgf5) increased the DP population. Time-lapse imaging directly confirmed that these changes reflected genuine differences in duration of the 2C-like state: OE shortened, whereas KO prolonged, the time cells spent in this state. These findings reveal that a Polycomb group factor controls not only entry into but also exit from the 2C-like state.\n\nID: 42584024\nTitle: 2026 Update on Clinical Trials in \u03b2-Thalassemia.\nAbstract: The therapeutic landscape of \u03b2-thalassemia has evolved rapidly over the past decade, shifting from a historical reliance on transfusion support and iron chelation toward disease-modifying and potentially curative therapies. This review summarizes the clinical development of novel treatments for both non-transfusion-dependent and transfusion-dependent \u03b2-thalassemia, including approved therapies, agents in active development, and programs that have been discontinued. Disease-modifying strategies have focused on improving ineffective erythropoiesis, correcting iron dysregulation, and restoring red blood cell metabolism. Luspatercept and mitapivat have demonstrated clinically meaningful improvements in hemoglobin levels and reduction of transfusion burden and are now approved in multiple jurisdictions. Additional pyruvate kinase activators, such as etavopivat, are undergoing clinical evaluation. Curative approaches have advanced substantially through gene addition, gene editing, and base editing technologies. Approved therapies, including betibeglogene autotemcel and exagamglogene autotemcel, have achieved high rates of durable transfusion independence, while emerging platforms aim to further improve efficacy, safety, and accessibility. At the same time, several promising approaches targeting fetal hemoglobin induction, iron metabolism, and ineffective erythropoiesis have failed to demonstrate sufficient clinical benefit despite preclinical proof of concept, highlighting the complexity of therapeutic development in \u03b2-thalassemia. Future priorities include refining patient selection, generating real-world and comparative effectiveness data, developing clinically meaningful response criteria, expanding pediatric access, and addressing the substantial cost and accessibility challenges associated with novel therapies.\n\nID: 42580267\nTitle: Clustered regularly interspaced short palindromic repeats\u2011associated protein 9 (CRISPR-Cas9) based genome editing in avian primordial germ cells: Comparative technologies, translational applications, and regulatory challenges.\nAbstract: Primordial germ cells (PGCs) are a unique platform for heritable gene editing in avian species, because they allow easy isolation, culture, and can then be reintroduced into the host. CRISPR/Cas9 technologies have advanced avian genome editing by enabling targeted editing of genes and traits for production, health, reproduction, and welfare. This review critically evaluates genome-editing tools in avian PGCs, including CRISPR/Cas9, transcription activator-like effector nucleases (TALENs), base editing, and prime editing. Germline transmission efficiency, suitability, precision, and heritability are compared. Efficiency, cytotoxicity, and translational feasibility of delivery strategies, including viral vectors, electroporation and the use of ribonucleoproteins are assessed. Applications of these techniques in chickens are for muscle growth via myostatin (MSTN) gene disruption, viral resistance via editing of the sodium/hydrogen exchanger 1 (NHE1) gene, and control of male and female ratios through modification of sex determination genes. Additionally, applications in biopharmaceutical protein production and animal biodiversity conservation are also explored. Despite advances, some limitations remain, including low efficiency of homology-directed repair, off-target effects, mosaicism, and variability in transmission through the germ line. Current evidence demonstrates a significant lack of germline validation and scalability creating barriers to translate this potential into commercial avian production, especially, poultry breeding. Regulatory frameworks and their implications for food and commercialization are also discussed. Future research should prioritize precision editing, scalable delivery systems, and regulatory alignment to enable practical, ethical, and responsible implementation.\n\nID: 42580028\nTitle: The future of clinical trials of mesenchymal stromal cells in acute graft-versus-host-disease.\nAbstract: The U.S Food and Drug Administration approval of remestemcel-L for pediatric steroid-refractory acute graft-versus-host disease (GVHD) marks the culmination of 2 decades of efforts to translate mesenchymal stromal cells (MSCs). However, the path to this milestone reveals a pattern of MSCs failing in late-phase clinical trials. Multiple sources of heterogeneity may explain these results, including variability in donor and recipient biology, product manufacturing and characterization, and trial design. For example, certain subsets of acute GVHD patients, particularly those with inflammatory/immune activation, may derive the greatest clinical benefit from MSCs. Trials failing to stratify for this patient-level heterogeneity risk failure while obscuring signals of efficacy in responsive subgroups. Improving trial design considering heterogeneity requires leveraging advances in MSC manufacturing and refining clinical trial methodologies. The development of pooled and early-passage MSCs, induced pluripotent stem cell-derived (iPSC)-MSCs, biomaterial-encapsulated MSCs, and gene-edited or chimeric antigen receptor-expressing MSCs may reduce heterogeneity and improve trafficking to and survival at disease sites. Equally important, trial methodologies must explicitly address heterogeneity from MSC manufacturing and patient enrollment. Adaptive/Bayesian designs and master protocols may allow multiple biomarkers and MSC products to be tested simultaneously, with successful combinations being translated into practice, drawing from strategies that have been successful in precision medicine.\n\nID: 42551134\nTitle: Epigenetic strategies for fetal hemoglobin induction in sickle cell disease.\nAbstract: Sickle cell disease (SCD) is caused by pathogenic variants in the \u03b2-globin gene (HBB), most commonly the variant responsible for hemoglobin S, and affects an estimated 515,000 newborns each year, with the highest burden occurring in sub-Saharan Africa. Gene editing and hematopoietic stem cell transplantation have changed the therapeutic landscape, but their cost, technical complexity, and procedure-related risks still limit their wider use. For this reason, pharmacological induction of fetal hemoglobin (HbF) remains an important therapeutic strategy. HbF reduces HbS polymerization and is associated with lower disease severity, morbidity, and mortality. Among the mechanisms involved in \u03b3-globin silencing, epigenetic regulation offers several targets that can be explored using small molecules. This review discusses medicinal chemistry approaches primarily targeting HDAC1/2, LSD1, and DNMT1, with emphasis on inhibitor classes, binding mechanisms, structural features, preclinical evidence, and translational limitations. The available data show that each target presents a distinct set of challenges. HDAC-directed strategies require improved isoform and cellular selectivity; LSD1 inhibitors must reconcile strong HbF induction with the risks associated with prolonged target engagement; and DNMT1 modulation is moving from DNA-incorporating nucleoside analogs toward reversible non-nucleoside inhibitors. We also discuss emerging approaches, including multi-target epigenetic modulation and targeted protein degradation. Together, these strategies show how a better understanding of \u03b3-globin repression may guide the development of safer and more accessible HbF-inducing agents.\n\nID: 42562919\nTitle: SLF2 and SMC5 dysfunction drives HSC aging and predisposes to MDS, defining a new inherited bone marrow failure syndrome.\nAbstract: Inherited bone marrow failure syndromes (IBMFS) comprise a heterogeneous group of genetic disorders and are associated with an increased risk of myelodysplastic syndromes (MDS). We and others recently identified pathogenic variants in SLF2 and SMC5 as the cause of Atelis Syndrome, a neurodevelopmental disorder accompanied by hematological abnormalities, including anemia and lymphopenia. However, the mechanisms underlying the associated hematopoietic dysfunction remain unclear. Through longitudinal follow-up and re-evaluation, we found that some patients developed MDS at a young age. To elucidate the bases of these hematopoietic defects, we analyzed hematopoietic progenitor cells (HPCs) derived from patient-specific induced pluripotent stem cells harboring compound heterozygous SLF2 mutations. Mutant HPCs exhibited impaired colony-forming capacity, defective erythroid differentiation with a myeloid bias, and markedly reduced engraftment in xenotransplantation assays. SMC5 knockdown in cord blood CD34+ cells impaired colony formation. Mechanistically, disruption of the SLF2-SMC5 axis induced genomic instability, p53/p21 activation, and a senescence-like phenotype. ATAC sequencing revealed epigenetic features characteristic of hematopoietic stem cell (HSC) aging, including increased chromatin accessibility at PU.1 motifs associated with myeloid bias. These findings demonstrate that SLF2 and SMC5 dysfunction drives premature HSC aging, bone marrow failure, and predisposition to MDS, revealing Atelis Syndrome as a previously unrecognized IBMFS.\n\nID: 42557593\nTitle: Biomarker implications of gene editing in hematologic diseases: latest updates from ASH 2025.\nAbstract: The 2025 American Society of Hematology (ASH) Annual Meeting highlighted rapid advances in gene editing for hematologic diseases, with increasing emphasis on precision editing and early exploration of in vivo delivery strategies. Beyond technological development, several measurable parameters are emerging as potential biomarkers, including fetal hemoglobin (HbF), F-cell proportion, HbF/F-cell, editing durability, and long-term clonal monitoring. Clinical studies demonstrated that disruption of the BCL11A enhancer or editing of the HBG1/2 promoter can induce sustained HbF reactivation, which is associated with reduced transfusion burden or transfusion independence in transfusion-dependent \u03b2-thalassemia and improved clinical outcomes in sickle cell disease. Near-pancellular HbF distribution and HbF/F-cell levels above anti-sickling thresholds further support the pharmacodynamic value of HbF-related biomarkers. Long-term follow-up studies have also incorporated editing durability and clonal monitoring into safety assessment frameworks. Emerging platforms such as RNA Gene Writer and CD90-targeted virus-like particles have demonstrated the feasibility of in vivo hematopoietic stem cell editing, although challenges related to targeting efficiency, delivery specificity, immunogenicity, and long-term safety remain. Overall, ASH 2025 suggests a shift from achieving gene editing to quantifying efficacy, durability, and safety, with standardized biomarker frameworks likely to play an increasingly important role in future clinical translation.\n\nID: 42555924\nTitle: Smart Scaffolds: How WD40 Proteins Integrate Plant Development, Metabolism, and Stress Adaptation.\nAbstract: WD40 repeat proteins are evolutionarily conserved molecular scaffolding that function as key regulators of plant growth, development, and stress resilience. These proteins, highlighted by tandem WD (Trp-Asp) motifs forming a stable \u03b2-propeller structure, serve as versatile platforms for protein-protein and protein-DNA interactions, facilitating the assembly of multiprotein complexes and the integration of environmental and hormonal signals into specific physiological responses. In plants, WD40 proteins orchestrate essential functions such as anthocyanin biosynthesis, blooming timing, embryogenesis, gametogenesis, and fruit development, often through regulatory modules like the MYB-bHLH-WD40 (MBW) complex. In addition to development, they serve as crucial centers for adaptation to abiotic and biotic stress by regulating phytohormonal interactions, maintaining reactive oxygen species balance, and facilitating ubiquitin-mediated protein degradation, especially via SCF E3 ligase complexes. These roles relate significant hormone pathways, such as abscisic acid, auxin, gibberellin, ethylene, and brassinosteroids, to environmental interactions. Recent progress in CRISPR-based functional genomics, interactome mapping, and high-resolution structural modeling is revealing the plasticity and evolutionary conservation of WD40 scaffolds. This review strengthens current findings relating their structural properties, molecular mechanisms, and functional diversity, underscoring their potential as targets for developing stress-resilient, high-yield crops in a changing climate.\n\nID: 42545527\nTitle: A Reproducible Electroporation Strategy for CRISPR-Cas9 RNP and mRNA Delivery in Fish Embryos.\nAbstract: This study presents a streamlined electroporation-based method for efficient macromolecular delivery into zebrafish embryos. We first characterized the physical barrier posed by the chorion using TEM (Transmission Electron Microscope) and established that its removal is prerequisite for effective delivery. A systematic optimization of electroporation parameters for dechorionated embryos identified optimal conditions (e.g., poring pulse: 25\u00a0V, 20 ms; transfer pulse: 5\u00a0V, 50 ms) that ensured high embryo survival and robust eGFP mRNA transfection. Applying this protocol, we achieved targeted gene knockout by electroporation-mediated delivery of Cas9 ribonucleoproteins (RNPs) against multiple loci. Targeting the tyr locus resulted in a phenotypic albinism rate of (38.6\u2009\u00b1\u20093.30)%. Furthermore, we incorporated polyglutamic acid (PGA) to modify the RNP complexes (target tyr), which inhibited aggregation and enhanced editing efficiency to (44.45\u2009\u00b1\u20091.41)%, outperforming a commercial. electroporation system, while targeting the pigmentation-related gene slc24a5 yielded an albinism or hypopigmentation rate of (38.33\u2009\u00b1\u20092.62)%. In addition, targeting the development-associated gene ddx19b produced developmental defect phenotypes in (38.33\u2009\u00b1\u20091.88)% of embryos. The successful introduction of indels at the target site was confirmed by sequencing. Our work establishes a highly effective electroporation strategy, augmented by nanotechnology, for the delivery of mRNA and RNP complexes, enabling high-efficiency protein expression and gene editing in zebrafish embryos, with broad potential applications in aquatic biotechnology.\n\nID: 42538913\nTitle: A highly penetrant LMNA R541C variant associated with dilated cardiomyopathy leads to dysregulation in metabolism and proliferation pathways in stem cell-derived cardiomyocytes.\nAbstract: LMNA codes a widely expressed nuclear cytoskeletal protein (lamin A/C) with multiple important functions. Pathogenic LMNA genetic variation may lead to autosomal dominant cardiomyopathy, though the severity and rate of progression can vary with the specific nucleotide change and location. Prior studies showed that induced pluripotent stem cells (iPSC)-derived cardiomyocytes (iCMs) with LMNA R541C exhibited reduced LMNA protein abundance, increased sarcomere disorganization, and abnormal electrophysiology. We investigated the LMNA-R541C variant that exhibits a highly penetrant and severe clinical cardiomyopathy phenotype using transcriptomic analysis of iCMs. Patient-derived iPSCs with CRISPR-corrected (clustered regularly interspersed short palindromic repeats) isogenic control cells and CRISPR knock-in LMNA-R541C heterozygous iPSCs were generated for isogenic controlled experiments. In differential gene expression analyses we observed that LMNA R541C/WT iPSC-derived cardiomyocytes had consistent perturbations in 123 genes across CRISPR-corrected and knock-in experiments compared to controls. Pathway analysis identified that the G2M checkpoint and oxidative phosphorylation processes were consistently dysregulated and confirm these findings in previously published iPSC and murine models. These results implicate perturbed gene expression and pathways that may contribute to the severe phenotypes in LMNA-R541C. Informatic analysis of pathways suggests several drug classes including multiple cardiac glycosides as potential targeted therapeutic candidates to be explored.\n\nID: 42533346\nTitle: Cardiac function in zebrafish embryos is linked to an androgen receptor-adrenomedullin-proepicardium axis.\nAbstract: Congenital heart defects (CHDs) comprise the most common congenital malformation affecting nearly 1% of all newborns. In individuals with sex chromosome aneuploidy syndromes, however, the prevalence reaches up to 50% of all livebirths. One commonality to these syndromes is a marked reduction in sex hormones, particularly androgens. Androgen receptor (Ar) insufficiency represents a culprit in the pathophysiology of adult onset cardiovascular disease and arrhythmia, but there are no reports regarding Ar function during heart development. This is surprising as androgens along with its nuclear receptor exist already during early development, even before gonads develop and become functional. We evaluated the role of the Ar during vertebrate heart development by generating loss-of function in zebrafish embryos via pharmacological inhibition, transient CRISPR/Cas9 treatment, or interference of splicing as well as murine cell culture. Attenuation of Ar function in zebrafish embryos prevents normal cardiac morphology and physiology as apparent by edema, bradycardia and arrhythmia. Molecularly, we identified increased abundance of adrenomedullin (Adm) 2a as a likely cause for the observed defects. Cellularly, these phenomena may be linked to impaired formation of proepicardial cells, which are reported to intermingle with cells of the conduction system and influence cardiac pacing. A disrupted Ar - Adm2 axis possibly contributes to the increased frequency of CHD in individuals suffering from sex chromosome aneuploidy syndrome. Testosterone function is generally mediated by androgen receptors in the nucleus of the cell. Interestingly, the androgen receptor exists already in early embryos, long before sexual maturation will be initiated. This study aimed to investigate the function of the androgen receptor during heart development using zebrafish embryos. Embryos lacking functional androgen receptors display severely impaired heart development resulting in a slower and irregularly beating heart. Consistently, several important structures of the heart including the conduction system necessary for cardiac rhythmicity fail to form and function properly in the absence of androgen receptor function. Loss of androgen receptor function leads to elevated expression of adrenomedullin 2a, which has previously been implicated in heart development and function. Consistent with a study reporting adrenomedullin 2a originating from the proepicardium loss of proepicardial genes could be observed in the absence of the androgen receptor. Taken together, this study identifies a novel role of the androgen receptor during early heart development, most likely independent of the later biological sex.\n\nID: 42528196\nTitle: Human iPSC-derived fetal granulosa-like cells enhance oocyte maturation outcomes and enable multi-generational safety evaluation in a mouse IVM model.\nAbstract: In vitro maturation (IVM) of germinal vesicle oocytes may broaden assisted reproductive technologies; however, developmental competence remains limited by the lack of standardized follicular somatic support. We generated an endogenous FOXL2-P2A-tdTomato reporter human induced pluripotent stem cell (hiPSC) line using CRISPR/Cas9 knock-in and reporter-guided transcription factor (TF) programming to produce fetal granulosa-like cells (FGLCs). A flow cytometric TF screen identified TCF21, WT1-KTS, and NR1H4 as the strongest FOXL2 inducers, and combinatorial optimization showed that removing TOX3/ETV5 and adding NR2F2 substantially increased the FOXL2-positive fraction. Bulk RNA-seq, principal component analysis, and TF activity inference positioned the induced cells close to early-gestational human fetal granulosa cell profiles. In a mouse IVM, in vitro fertilization (IVF), blastocyst culture, and embryo transfer pipeline, FGLC supplementation did not change nuclear maturation rates but improved downstream development, most clearly increasing offspring production from cumulus-oocyte complexes. A comprehensive safety assessment of F0 offspring derived from FGLC-treated oocytes revealed a normal sex ratio, postnatal growth, gross anatomy, gonadal histology, and modified SHIRPA neurobehavioral profiles. Next-generation natural mating and germ cell assays demonstrated preserved fertility, normal IVF outcomes, and normal sperm parameters in the F1 generation. These results establish a scalable strategy for generating fetal granulosa-like supporting cells from hiPSCs and provide an effective and multi-generational safety framework for oocyte-contact IVM interventions.\n\nID: 42518103\nTitle: Public knowledge, attitudes, and ethical views on CRISPR-Cas9 gene editing for genetic diseases in Taif, Saudi Arabia.\nAbstract: Public support for gene editing, particularly for therapeutic purposes, remains strong. Recently, the Ministry of Health in Saudi Arabia approved CRISPR-Cas9 for treating Sickle Cell Disease and beta thalassemia. This study aims to assess the Taif population's opinion on gene editing and their knowledge of genetic modification. In this cross-sectional study, a questionnaire was distributed online from March 2, 2024, to June 15, 2024, to 747 residents of Taif City aged 18 and older. Among the respondents, 14.7% reported that they or their family members suffer from a hereditary disease, and 65.7% either work or study in the healthcare field or have a family member involved in healthcare. Additionally, 50.7% had previously heard of genetic modification. Marital status, number of children, and education level did not significantly influence opinions on genetic editing, whereas affiliation with the healthcare field was significantly associated with greater acceptance\u00a0(p\u2009=\u20090.023), while a family history of hereditary disease showed a trend toward significance (p\u2009=\u20090.055). Public opinion strongly supports using genetic editing to treat life-threatening diseases in adults and embryos (63.2% and 73.6%, respectively). However, opinions are more divided on non-disease traits. Many respondents expressed interest in enhancing intelligence (73.8%) and strength (75.8%), as well as altering height (67.8%) and hair color (60.7%). While support was strong for therapeutic use, opinions were divided on enhancement, reflecting ethical tension despite high interest in modifying non-disease traits. Notably, 50.7% believed that using genetic editing for non-medical purposes crosses ethical boundaries and exceeds nature's limits. Awareness of gene-editing techniques was not significantly associated with acceptance (p\u2009=\u20090.108). In conclusion, public acceptance of gene editing in Taif is high, particularly among healthcare-affiliated individuals. Increasing public awareness remains essential to bridge ethical concerns and support informed engagement.\n\nID: 42512296\nTitle: Development of a Cre-Inducible Rabl6a Transgenic Mouse Model That Enhances Sarcoma Growth In Vivo.\nAbstract: Background: Malignant peripheral nerve sheath tumors (MPNSTs) are deadly sarcomas that arise from Schwann cells and lack effective therapies. RABL6A is an oncogenic Rab-like GTPase whose expression is associated with worse survival in many human cancers. It is required for human MPNST cell survival, and its expression is dramatically increased in patient MPNSTs compared to benign precursor lesions. Methods: To model elevated expression of RABL6A in vivo, we developed transgenic mice expressing Cre-inducible Rabl6a. These Rabl6a-tg mice express the murine Rabl6a cDNA with a 5' hemagglutinin [HA] epitope sequence downstream of a CMV enhancer and separated by a lox-stop-lox cassette. Double transgenic DhhCre; Rabl6a-tg mice were generated to achieve Schwann-cell specific Cre expression from the Desert hedgehog (Dhh) promoter. De novo MPNSTs were induced by CRISPR editing of Nf1, Ink4a, and Arf genes in the mouse sciatic nerve. Results: Cre-dependent expression of transgenic Rabl6a was verified at the mRNA and protein levels in Cre-positive mouse embryo fibroblasts and tissues. Increased Rabl6a expression in DhhCre; Rabl6a-tg mice had no effect on de novo MPNST initiation but significantly accelerated tumor progression relative to DhhCre control mice. The Rabl6a phenotype was associated with increased tumor angiogenesis but not proliferation. Interestingly, many MPNSTs in the DhhCre background exhibited varying levels of rhabdomyoblastic (RMB) features. That immature muscle cell phenotype is a hallmark of malignant Triton tumors, a rare histological variant of human MPNSTs associated with worse outcomes. Conclusions: These data provide direct evidence that Rabl6a is a functional driver of MPNSTs while establishing Rabl6a-tg mice as a suitable model for investigating Rabl6a's role in other lethal RABL6A-high tumors.\n\nID: 42511636\nTitle: Efficient Gene Editing in Fish Primary Germline Stem Cells.\nAbstract: Genome editing by the CRISPR/Cas9 system is widely used for production of gene-modified animals, including fish. However, efficient gene editing in fish cultured cells, in particular germline stem cells (GSCs), is challenging, likely due to the difficulty in transfecting these cells. The ricefield eel (Monopterus albus), a sequential hermaphroditic species, is a freshwater fish of significant economic value in China. In this work, we report a simple method that can achieve high gene editing efficiency in primary GSCs of fish species, including ricefield eel. High transfection efficiency (50-95%) is achieved in fish GSCs by using a microchannel-based cell transfection system. Gene editing efficiency of up to 60% in primary ricefield eel GSCs is achieved using an integrated CRISPR/Cas9 vector strategy. High gene editing efficiency is also achieved in gibel carp (Carassius gibelio) GSCs and the medaka spermatogonial stem cell line SG3, demonstrating the general applicability of our method. Our data suggest that efficient transfection is key to high gene editing efficiency in fish cultured GSCs. This study establishes an efficient and reliable gene editing system for fish GSCs, which may facilitate the creation of new germplasm of genetically difficult-to-breed fish by combining GSC transplantation with gene editing techniques.\n\nID: 42510922\nTitle: Gene-Edited Stem Cells for Ischemic Vascular Disease: Current Advances and Future Perspectives.\nAbstract: Ischemic vascular diseases remain a leading cause of morbidity and mortality worldwide and are frequently associated with irreversible tissue damage. Although stem cell-based therapies have shown promise for vascular regeneration, their clinical translation has been limited by poor survival, insufficient engraftment, functional heterogeneity, and immune rejection. Recent advances in genome-editing technologies, including CRISPR/Cas9, base editing, and prime editing, have provided powerful tools for overcoming these limitations through precise genetic modification of stem cells. Gene editing can enhance angiogenic potential, improve resistance to ischemic stress, augment paracrine activity, promote endothelial maturation, and reduce immunogenicity. In this review, we outline the current genome-editing toolbox and its application to stem cell engineering for vascular regeneration in ischemic disease. We also examine emerging therapeutic concepts, universal donor cell platforms, and key issues in safety and ethics, with a focus on translational pathways. Taken together, advances at the interface of genome editing and stem cell biology are likely to accelerate the development of regenerative therapies that deliver more durable vascular repair in ischemic vascular disease.\n\nID: 42510769\nTitle: Oligonucleotide Synthesis Errors Are a Source of Untoward Variation in HDR-Mediated Gene Editing.\nAbstract: Background/Objectives: Single-stranded oligonucleotides (ssODNs) are used as donor templates for therapeutic gene editing by CRISPR-Cas9 cleavage and homology-directed repair (HDR). Although ssODN sequence fidelity is critical to the safety and efficacy of editing, standard quality control methods cannot resolve individual nucleotide errors. Methods: We performed deep sequencing of ssODNs from three manufacturers and amplicons from edited hematopoietic stem/progenitor cells. Results: We find that synthesis errors are present in all ssODNs tested at rates that vary more than two-fold among manufacturers, at positions that are dependent on sequence context. These synthesis errors are propagated into the genome by HDR at frequencies proportional to their abundance in the ssODN. In our sickle cell mutation correction protocol, the most prevalent SNEs are predicted to produce benign \u03b2-globin variants, while the less frequent frameshift deletions are predicted to generate \u03b2-thalassemia-like alleles. Conclusions: Current quality control standards are insufficient to detect these errors, and deep sequencing of ssODNs should be incorporated into regulatory submissions for clinical gene editing programs.\n\nID: 42505392\nTitle: SOX15 Contributes to the Maintenance of Pluripotency in Porcine Embryonic Stem Cells.\nAbstract: Understanding how pluripotency regulatory networks evolve across mammals remains a central question in developmental and stem cell biology. While rodent models have defined the canonical core circuitry of pluripotency, the extent to which these regulatory hierarchies are conserved in large mammals is unclear. Here, we provide evidence that SOX15 contributes to the species-specific regulatory network as a modulator that sustains pluripotency and preserves functional differentiation capacity in porcine embryo-derived stem cells. Comparative sequence analysis revealed strong conservation of the SOX15 HMG domain across mammals, yet promoter divergence suggested lineage-specific regulatory evolution. Transcriptomic profiling demonstrated that, unlike in mice, SOX15 is robustly upregulated from the 2-cell stage and remains highly expressed in the porcine epiblast, coinciding with key windows of pluripotency establishment. In porcine embryo-derived stem cells, stable SOX15 knockdown resulted in reduced colony integrity, diminished alkaline phosphatase activity, impaired proliferation, and downregulation of core pluripotency genes, including OCT4 and NANOG. Furthermore, loss of SOX15 disrupts embryoid body formation and abolishes teratoma-forming capacity in vivo. This deficit likely reflects impaired pluripotency, but may also be attributed to compromised cell survival or proliferative fitness following transplantation. Notably, comparable perturbations in mouse models do not produce equivalent phenotypes, underscoring a lineage-dependent functional divergence. Together, our findings suggest that SOX15 contributes to the support of the porcine pluripotency network, and hint at evolutionary plasticity in the hierarchical architecture of mammalian pluripotency. These findings move beyond the rodent-centric paradigm and offer a refined perspective on the evolutionary plasticity of pluripotency networks, highlighting SOX15 as a pivotal lineage-specialized node governing naive pluripotency in large mammals. Notably, these inferences are based on functional perturbation using a single validated miRNAi construct; definitive confirmation of SOX15-specific causality will require future orthogonal validation via independent knockdown sequences, CRISPR interference, or RNAi-resistant rescue experiments.\n\nID: 42501539\nTitle: DAZL-targeted inducible kill switches enable efficient ablation of chicken primordial germ cells.\nAbstract: Competition from endogenous primordial germ cells (PGCs) in recipient embryos limits the generation of fully donor-derived offspring in avian surrogate-host systems. An inducible and germline-restricted ablation strategy is therefore needed to create sterile recipients without compromising somatic development. Using CRISPR/Cas9-mediated homology-directed repair, we inserted three inducible suicide-gene cassettes (iCaspase9, RapaCasp9, and CD) into the endogenous DAZL locus of chicken PGCs. All knock-in lines showed stable reporter expression and retained typical PGC morphology. Comparative functional analyses identified iCaspase9 activated by AP20187 as the most sensitive and specific ablation system, achieving near-complete killing at nanomolar concentrations without detectable toxicity in control cells. RapaCasp9 induced with rapamycin also ablated engineered PGCs efficiently, but rapamycin caused marked non-specific growth inhibition in control cells. Replacing rapamycin with the synthetic A/C heterodimerizer AP21967 largely eliminated this off-target toxicity while preserving rapid and robust killing. By contrast, yeast-derived CD variants did not substantially improve 5-fluorocytosine sensitivity in chicken PGCs. DAZL-restricted iCaspase9/AP20187 and the optimized RapaCasp9/AP21967 system provide efficient inducible kill switches for chicken PGCs in vitro. These platforms establish a practical genetic toolkit for generating sterile surrogate hosts to support avian genome editing, germline replacement, and Sire Dam Surrogate breeding.\n\nID: 42635115\nTitle: One-pot SP-EXPAR-integrated CRISPR/Cas14a assay for highly specific and versatile detection of ctDNA mutations in lung cancer patients.\nAbstract: The highly specific and versatile detection of KRAS mutations in circulating tumor DNA (ctDNA) from plasma has critical clinical implications for non-small-cell-lung cancer (NSCLC). However, conventional isothermal amplification methods suffer from poor single-base discrimination, while CRISPR-12a-based detection is highly protospacer adjacent motif (PAM)-dependent. To address these challenges, a one-pot self-primer isothermal exponential amplification reaction (SP-EXPAR) combined with a CRISPR/Cas14a assay was developed for detecting KRAS G12C and G12D. Two synergistic strategies were devised to ensure high specificity: first, a carefully designed hairpin probe that permits selective amplification of mutant over wild-type sequences through differential binding affinity; second, optimization of the Cas14a sgRNA seed region, with the mutation positioned at the 11th nucleotide for stringent target recognition. The assay is further distinguished by a physical separation design, in which the Cas14a reagents are pre-loaded into the tube cap and mixed with the amplification products only after SP-EXPAR completion. This assay enables KRAS G12C detection within 1 h, with a limit of detection of 81.9 aM (0.1% mutation percentage) and a dynamic range from 100 aM to 1 nM. Furthermore, this assay further demonstrates its programmability and was successfully applied to detect KRAS G12D with comparable performance. In detecting 42 clinical samples, this assay demonstrated 100% sensitivity and 100% specificity compared with DNA sequencing. This approach holds great potential in disease diagnosis.\n\nID: 42628531\nTitle: Historical metabolic adaptation potentiates the rapid evolution of flonicamid resistance in Myzus persicae.\nAbstract: Rapid adaptation to novel environments is often shaped not only by newly acquired mutations but also by historical genetic backgrounds established through prior evolutionary events. However, the extent to which such historical contingency contributes to the rapid evolution of insecticide resistance remains poorly understood. Here, we investigated the emergence of resistance to flonicamid, a recently deployed insecticide, in the green peach aphid, Myzus persicae. We show that constitutive overexpression of the P450 enzymes CYP6CY3 and CYP6CY4, already widespread in populations of M. persicae before flonicamid deployment, confers a previously cryptic tolerance phenotype to flonicamid. However, biochemical and transgenic analyses demonstrated that these metabolic adaptations provide only weak protection against flonicamid. Following flonicamid deployment, however, a novel target-site mutation, NaamV251I, in the recently identified molecular target of 4-trifluoromethylnicotinamide (TFNA-AM), emerged in M. persicae on a genetic background of CYP6CY3 or CYP6CY4 overexpression. Structural modeling, enzymatic assays, and CRISPR-Cas9 genome editing demonstrated that this mutation reduces target sensitivity and independently confers moderate resistance. Strikingly, combining the nicotinamidase (Naam) mutation with pre-existing CYP6CY3 or CYP6CY4 overexpression produced substantially elevated resistance phenotypes that far exceeded the effects of either mechanism alone. Our results demonstrate that the pre-existing metabolic background did not itself evolve further following flonicamid deployment but fundamentally altered the phenotypic consequences of a subsequently acquired target-site mutation. These findings provide direct evidence that historical adaptive variation can potentiate rapid resistance evolution to newly introduced insecticides and reveal how interactions between past and contemporary adaptations shape evolutionary responses to novel environmental challenges.\n\nID: 42628204\nTitle: Blocking the conversion of \u03b2-carotenoids into xanthophylls through HYb gene editing via CRISPR/Cas9 confers enhanced heat stress tolerance in Nicotiana tabacum.\nAbstract: Plants produce protective metabolites to withstand stress, and \u03b2-carotenoids act as crucial antioxidants. \u03b2-Carotene is converted into xanthophylls by \u03b2-carotene hydroxylase (BCH). In this study, the BCH gene in Nicotiana tabacum was targeted using CRISPR/Cas9 genome editing to redirect metabolic flux toward \u03b2-carotene accumulation and evaluate its effects on heat tolerance. Following Agrobacterium-mediated transformation with a BCH-specific gRNA, three mutant plants were obtained; two carrying frameshift mutations (P1 and P3) and one with mis-sense mutations (P2). A significant increase in chlorophyll contents was observed in the edited lines compared with wild-type plants. Interestingly, the frameshift mutants exhibited substantial increase in total chlorophyll (71% and 31% in P3 and P1 respectively) as compared to mis-sense mutant P2 (18%). Further, biochemical profiling using HPLC showed that the edited plants accumulated 3.74-fold increase in \u03b2-carotene than wild-type plants. Under heat stress (42\u202f\u00b0C for 96\u202fh), the edited plants exhibited enhanced thermotolerance by remaining greener and delayed wilting, whereas wild-type plants developed necrosis rapidly under heat stress. This enhanced thermotolerance might has resulted from the increased expression of \u03b5-cyclase (an upstream key enzyme in \u03b2-carotene biosynthesis) as revealed by expression profiling of edited plants. In contrast, the expression of downstream \u03b2-cryptoxanthin and zeaxanthin biosynthetic genes was reduced, which seems consistent with mutation of BCH. DAB staining further confirmed reduced ROS accumulation in edited plants as compare to wild type supporting the protective role of \u03b2-carotene. In summary, the downregulation of BCH in N. tabacum boosted \u03b2-carotene levels and chlorophyll retention, enhancing heat stress tolerance. These findings demonstrate the potential of targeting carotenoid biosynthesis to improve crop resilience.\n\nID: 42626030\nTitle: Mutation-Immune Crosstalk Contextualizes CAF-Associated ARPC1A Programs and Cisplatin Response in Gastric Cancer.\nAbstract: Cisplatin response in gastric cancer is shaped by malignant cell programs, stromal states, and mutation-immune crosstalk, but the CAF subtypes linked to platinum tolerance and their epithelial effectors remain incompletely defined. We integrated single-cell RNA sequencing, epithelial CNV-like inference, fibroblast reclustering, CellChat analysis, signature scoring, hdWGCNA, CAF-epithelial coupling, exploratory GSE14209 evaluation, TCGA-STAD mutation/copy-number contextualization, and DepMap CRISPR virtual knockout analysis, followed by experimental validation in AGS and HGC-27 cells. IGF1+ CXCL12+ CAFs showed resistance-supportive stromal features, and CAF-epithelial coupling prioritized ARPC1A as a tumor epithelial candidate associated with this stromal program. In TCGA-STAD, ARPC1A mutations were rare and consisted of three missense and two frameshift variants without a recurrent hotspot; the mutant tumors were confined to the MSI subtype and showed an immune-activated, high TMB/MSI context, indicating mutation-immune crosstalk rather than a clear mutation-specific CAF, EMT, drug resistance, or cisplatin response phenotype. By contrast, ARPC1A copy-number gain/amplification was more frequent and tracked with ARPC1A expression, CIN enrichment, aneuploidy, and fraction of genome altered. DepMap CRISPR data indicated mostly weak-to-mild baseline ARPC1A dependency in upper GI and gastric/GEJ models. Experimentally, ARPC1A knockdown increased cisplatin sensitivity, promoted cisplatin-induced apoptosis, and suppressed migration and invasion. These findings identify a CAF-associated ARPC1A epithelial program linked to cisplatin response and support a mutation-immune/copy-number framework in which ARPC1A is interpreted mainly through immune-contextual mutation patterns and expression dosage rather than recurrent gain-of-function mutation.\n\nID: 42625528\nTitle: Four new Duchenne muscular dystrophy mouse models with clinically relevant exon deletions in the human DMD gene.\nAbstract: Mutation specific therapeutic approaches, like exon skipping or gene-editing, hold promise for the treatment of Duchenne muscular dystrophy (DMD). Translatability of preclinical studies investigating these approaches could greatly be improved through the use of humanized mouse models, as these allow preclinical testing of human specific sequences. We developed four novel humanized DMD mouse models with either a deletion of exon 44, 45, 51 or 53 in the human DMD gene, in a mouse dystrophin negative background (mdx mouse; exon 23 nonsense mutation). Our optimized prescreening pipeline allowed us to do so very efficiently with the CRISPR-Cas9 technology. We confirmed either complete lack of dystrophin, or expression of trace levels, which led to development of muscle pathology consisting of muscle fiber de-, and regeneration, inflammation and fibrosis in young adult mice. Intramuscular treatment with vivo-morpholinos targeting a flanking exon induced exon skipping in the DMD strains, which restored the disrupted open reading frame and subsequently dystrophin expression. This validates these models as valuable tools for preclinical studies investigating human sequence specific therapeutic approaches for DMD.\n\nID: 42625114\nTitle: Molecular pathways and emerging therapeutic strategies in advanced thyroid cancer: from targeted therapy to precision oncology.\nAbstract: The most prevalent endocrine cancer is thyroid cancer. It may act in a very disparate manner; ranging between slow growing, well differentiated tumours to an aggressive anaplastic subtype. Initial treatment with standard therapy, surgery, radioactive iodine, the thyroid-stimulating hormone inhibition and in some cases, chemotherapy or external-beam radiations are effective with the differentiated cancers at the early stages. Nevertheless, there is no choice with tumours, which become unresponsive to iodine, metastasized, or un- differentiated. Recent developments in molecular oncology have elucidated the genetic alterations that contribute to thyroid cancer, in particular, the MAPK and PI3K/AKT/mTOR pathways, and BRAF, RAS, RET, and TERT promoter mutations. The current review summarizes the changing therapeutic environment of thyroid cancer that includes established targeted medicines and novel developments. These are immune checkpoint inhibitors, redifferentiation based on reinstatement of iodine uptake, selective RET and BRAF/MEK, RNA-based therapeutics, CRISPR gene editing, oncolytic virotherapy, peptide receptor radionuclide therapy, alpha-particle radiotherapy, and nanotechnology-based drug delivery systems. A combination regimen involving molecular targeting and immunotherapy or radioactive iodine is also improving the disease in advanced disease. Collectively, the advances are an indication of a transition to the personalized, mechanism-driven treatment strategies that would prolong the survivability of patients with advanced thyroid cancer, conquer resistance, and reduce systemic toxicity.\n\nID: 42624823\nTitle: Partial deletion in the cuticular protein gene BmorCPR2 results in a body shape mutant in silkworm, Bombyx mori L. (Lepidoptera: Bombycidae).\nAbstract: The Bombyx mori L. (Lepidoptera: Bombycidae) is a significant economic insect used for silk production. A novel body shape mutant, stony^sunken (st^sk), that exhibits a sunken intersegmental membrane was isolated from the wild type of st^sk (WT-n08). Investigation indicated that the mutation had no significant effect on its growth and development. To elucidate the molecular mechanism underlying this body shape mutant, genetic analysis, positional cloning, and the CRISPR/Cas9 gene editing system were performed. Genetic analysis demonstrated that the mutant trait in st^sk is controlled by an autosomal recessive gene and follows Mendelian inheritance. Positional cloning showed that a putative cuticular protein gene, BmorCPR2 on chromosome 8, was the candidate gene. Sequencing analysis revealed partial deletion of BmorCPR2 exon 2 and intron 2 sequences occurred and subsequently resulted in the premature termination of gene expression. Knock-out of BmorCPR2 using the CRISPR/Cas9 gene editing system led to the sunken intersegmental membrane phenotype. These findings highlight the essential role of BmorCPR2 in silkworm cuticular formation, providing a foundation for further research on cuticular protein function.\n\nID: 42620346\nTitle: APP Dosage and Extracellular Domain Variants Drive Distinct Defects in Neurogenesis modeled in Down Syndrome iPS cells.\nAbstract: The amyloid precursor protein (APP) is heavily studied as the source of amyloid beta in Alzheimer's disease (AD), however, the complex functions of APP remain poorly understood, as does the impact of APP dosage on neurodevelopment. Here we study APP specifically in the context of Trisomy 21. In an effort to reduce APP dosage in trisomy 21 iPSCs, we generated trisomic isogenic lines which vary in APP dosage, including a full APP knock-out line, as well as lines carrying mutations of the APP extracellular domain. We used a panel of these lines to study potential impacts of APP dosage or structure on two distinct steps of neurogenesis in trisomic cells: 1) terminal differentiation of human neuro-progenitor cells (NPC) to post-mitotic neurons and 2) neuron structure as reflected in neurite outgrowth. Complete loss of APP causes marked defects in each of these two distinct steps, reducing both the terminal differentiation of NPCs to neurons, and proper neurite development for extended neuron structure. Hence, APP is necessary for both aspects of normal neurogenesis. Further analyses of the null and other mutant lines indicate that APP likely impacts these two distinct steps by two different mechanisms. Collective results suggest that the reduced terminal differentiation of NPCs reflects an effect of APP dosage, whereas the defects in neurite extension are due to structural mutation of the APP extracellular domain. Absence of APP or reduced (monosomic) APP dosage prolonged the cycling of trisomic NPCs, which is known to be regulated by Notch signaling. APP and Notch are the main targets of gamma-secretase cleavage, hence we hypothesized that APP dosage may impact neurogenesis indirectly, potentially via effects on Notch signaling. To test this, we treated NPCs with Compound E which inhibits gamma-secretase (and Notch signaling); results show this restored levels of neurogenesis in APP depleted lines, supporting an indirect effect of APP dosage . In contrast, results indicate that disruption of APP extracellular domain integrity impacts neurite extension via a more direct role of APP in neuron structural maturation. This study describes a resource of well-characterized APP mutant isogenic DS iPSC lines, implicates a dynamic interplay between APP dosage and Notch signaling, and raises new questions about the impact of APP dosage in orchestrating neural progenitor fate decisions during human brain development, specifically in the context of trisomy 21.\n\nID: 42612424\nTitle: Development of a human iPSC and patient phenotyping resource for preclinical investigations of neurodevelopmental disorders.\nAbstract: In this manuscript, we report the development of a comprehensive resource designed to harness the transformative potential of patient-derived induced pluripotent stem cells (iPSCs) to advance the study of neurodevelopmental disorders (NDDs). Using CRISPR-Cas-mediated genome editing, the Human Neuron Core generated a repository comprising 29 isogenic iPSC pairs, two sex-matched parental control iPSC pairs, and one unmatched patient line representing six monogenic NDDs: Tuberous Sclerosis Complex, PTEN Hamartoma Tumor Syndrome, KCNQ2 Developmental and Epileptic Encephalopathy, FOXG1 Syndrome, Phelan-McDermid Syndrome, and SETBP1 Haploinsufficiency Disorder. In parallel, detailed clinical phenotyping data were collected to enable comparison of cellular phenotypes with clinical severity in future studies. This integrated collection of genetically defined iPSC lines and associated clinical data provides a powerful platform for investigating disease mechanisms and advancing iPSC-based drug discovery for NDDs.\n\nID: 42612103\nTitle: Genome Editing in Primary Mammalian Cells via Electroporation of Editor RNA.\nAbstract: CRISPR editors including nucleases, base editors, and prime editors can efficiently correct disease-causing genetic variants or disrupt target genes. Editing outcomes are commonly evaluated in cultured primary cells, patient-derived cells, or engineered cell lines to study the impact of genetic variation or as a first step before initiating animal studies or clinical translation. Delivery of editors as mRNA together with synthetic guide RNAs into mammalian cells can improve editing efficiency relative to plasmid-based approaches and prevent issues such as DNA integration or off-target editing from sustained expression. This article presents a workflow to prepare genome editor mRNA by in vitro transcription (IVT), including co-transcriptional capping and chemically-modified nucleotides, electroporate editor mRNA and guide RNAs into primary human fibroblasts, induced pluripotent stem cells (iPSCs), or lymphoblastoid cell lines (LCLs), and quantify editing outcomes by targeted amplicon sequencing on an Illumina platform followed by analysis using CRISPResso2. This workflow enables quantitative benchmarking of guide RNAs, electroporation parameters, and editor variants, and supports downstream applications including single-cell cloning, phenotypic assays, preclinical animal studies, and therapeutic development.\n\nID: 42611583\nTitle: CRISPR/Cas9-Mediated Site-Directed Mutagenesis of Genes in Klebsiella pneumoniae.\nAbstract: Constructing target-gene mutants with a common genetic background is crucial for elucidating gene function in antimicrobial resistance (AMR) research. Taking advantage of the single-guide RNA (sgRNA) and protospacer adjacent motif (PAM) sequence (3'-NGG) specificity of the Cas9 protein in the CRISPR/Cas9 (Clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9) system and codon degeneracy, the authors design a repair template that incorporates the desired point mutation while excluding the PAM sequence disrupted by a synonymous substitution, thereby preventing re-cleavage by CRISPR/Cas9. This method employs two available plasmids, pCasKP-apr and pSGKP-spe, offering straightforward operation and high screening specificity. As a result, the approach enables efficient generation of genetically defined mutant strains of Klebsiella pneumoniae (K. pneumoniae) and is readily adaptable to routine laboratory settings. Furthermore, the protocol minimizes off-target editing, shortens experimental timelines, reduces screening workload, and provides a reliable platform for investigating resistance mechanisms, validating candidate genes, and supporting functional genomics studies in clinically relevant bacterial pathogens.\n\nID: 42610742\nTitle: Energetic Determinants of Expanded PAM Recognition in Engineered FnCas9.\nAbstract: Expanding protospacer-adjacent motif (PAM) compatibility while preserving specificity remains a central challenge in CRISPR-Cas9 engineering. Francisella novicida Cas9 (FnCas9) exhibits high intrinsic specificity but is constrained by stringent PAM requirements. Here, we quantitatively examine the energetic and catalytic consequences of PAM-interacting mutations in three engineered variants, en1 (E1369R), en15 (E1603H), and en31 (G1243T/E1369R/E1449H), using a VEGFA3 DNA substrate framework. Microscale thermophoresis and isothermal titration calorimetry reveal that the engineered variants enhance binding affinity toward the canonical NGG PAM relative to wild-type FnCas9, with modest gains in binding free energy. Selected noncanonical PAM substrates, particularly TGA and TAG, also show improved binding by en15 and en31, with en31 displaying the strongest overall binding among the substrates tested. Thermodynamic profiles indicate that enhanced affinity is associated with more favorable enthalpic contributions, consistent with altered interactions at the PAM interface; however, the specific molecular contributions underlying these changes remain to be directly established. Despite improved binding, active-site titration reveals reduced fractions of catalytically competent enzyme in engineered variants, particularly en31, necessitating higher enzyme concentrations to achieve cleavage efficiencies comparable to wild-type. Cleavage assays demonstrate that en31 most effectively couples improved recognition of the tested noncanonical PAM substrates to productive catalysis, enabling robust cleavage of both TGA and TAG substrates while maintaining minimal off-target activity under the conditions examined. Together, these results suggest that PAM-interacting mutations in FnCas9 can alter the energetic coupling between DNA binding and catalytic activation within the VEGFA3 substrate framework tested, highlighting the importance of balancing substrate affinity with conformational activation in the design of high-precision genome-editing nucleases.\n\nID: 42608604\nTitle: Clinical and zebrafish studies of truncating SF3B2-variants in craniofacial microsomia.\nAbstract: Craniofacial microsomia (CFM) exhibits significant phenotypic variability and degree of severity. While loss-of-function variants in SF3B2 have recently emerged as a genetic etiology, the molecular basis underlying this clinical heterogeneity remains poorly understood. Here, we report two probands harboring novel truncating SF3B2 variants and presenting with distinct clinical phenotypes. Proband 1, with a heterozygous p.(Gln60*) variant, exhibited characteristic CFM features, including mandibular hypoplasia, cleft palate, bilateral tragal abnormalities, microtia, external auditory canal stenosis with hearing impairment, and an epibulbar dermoid. In contrast, Proband 2, carrying a p.(Lys507*) variant, exhibited a milder craniofacial phenotype, although he had hearing loss and developmental delay that could not be explained with certainty by the SF3B2-variant. Western blot analysis demonstrated complete loss of p.(Gln60*) protein, whereas the p.(Lys507*) variant-despite lying outside the predicted nonsense-mediated decay (NMD) escape region-retained 15.5% residual expression of truncated protein. To investigate functional consequences, we performed CRISPR/Cas9-mediated sf3b2 knockout in zebrafish. Mutant larvae showed a 25.33% malformation rate and recapitulated human craniofacial features, including a reduced head-to-body length ratio (p\u2009=\u20090.0013), hypoplastic mandibular cartilage-evidenced by shortened Meckel's cartilage (p\u2009=\u20090.0104) and Palatoquadrate (p\u2009=\u20090.0174)-and impaired skeletal mineralization (p\u2009=\u20090.0028). Together, these findings suggest that truncating variants at different positions may be associated with differential protein expression levels and variable clinical presentations. Our study reinforces SF3B2's role as a loss-of-function disease gene and highlights the importance of variant-specific molecular characterization in understanding CFM.\n\nID: 42607939\nTitle: The miRNA-virus axis in RNA virus infections: Mechanisms, therapeutic targeting, and systems biology approaches.\nAbstract: RNA viruses are a diverse and rapidly evolving group of pathogens that significantly contribute to worldwide morbidity and mortality, propelled by elevated mutation rates and effective use of host cellular mechanisms. MicroRNAs (miRNAs) have emerged as an essential post-transcriptional regulator of host-virus interactions, influencing viral replication, immunological responses and disease progression. This review offers a comprehensive overview of the miRNA-virus axis in RNA virus infections, highlighting the dynamic and context-dependent roles of host miRNAs. We investigate the mechanistic basis of miRNA-mediated regulation, including direct targeting of viral RNA, modulation of host dependency factors, regulation of antiviral signaling pathways, and immune-mediated effects on infection outcomes. We propose a functional categorization of miRNAs that transcends the conventional antiviral-proviral dichotomy, facilitating a more accurate comprehension of their involvement in various infection settings. This review connects mechanistic insights with translational applications by outlining novel treatment techniques, such as miRNA mimics, anti-miRs, RNA interference, and CRISPR-based methodologies. We also propose a therapeutic decision framework that links miRNA functional classification with targeted antiviral interventions. Key challenges including delivery efficiency, tissue specificity, and off-target effects are also discussed, with emphasis on lipid nanoparticles and exosome-based delivery systems. We further highlight the role of systems biology approaches, including multi-omics integration, single-cell and spatial transcriptomics, network analysis, and artificial intelligence, in identifying regulatory miRNA hubs and enabling precision antiviral medicine. Collectively, this review reinterprets the miRNA-virus axis as a dynamic regulatory network and provides a translational framework for the development of next-generation antiviral therapeutics.\n\nID: 42607937\nTitle: Integration of PNA-mediated PCR and CRISPR/Cas13a for highly sensitive detection of EGFR T790M mutation in circulating tumor DNA.\nAbstract: Circulating tumor DNA (ctDNA) is characterized by low abundance and fragmentation, limiting the development of genetic variant detection technologies. In this study, we established a highly sensitive and specific assay by combining peptide nucleic acid (PNA)-mediated PCR clamping with CRISPR/Cas13a trans-cleavage detection. A PNA probe targeting the wild-type (WT) EGFR T790M allele was designed to suppress WT amplification during PCR, while minimally affecting mutant allele amplification. By combining the target specificity of Cas13a for mutant alleles with the WT-suppression capability of PNA-PCR, we achieved a dual-enrichment effect for mutant detection. When applied to EGFR T790M mutation detection, the assay reached an analytical sensitivity of 0.02%. We established a standard curve for T790M detection using cell-free DNA standards. Clinical validation in 20 plasma samples from lung adenocarcinoma patients demonstrated that the PNA-Cas13a assay achieved a diagnostic sensitivity of 93.3% (95% CI: 68.1%-99.8%) and a specificity of 100% (95% CI: 47.8%-100%), with detection concordance comparable to or improved over ARMS-PCR in this pilot cohort. The results suggest its preliminary diagnostic utility in liquid biopsy. In conclusion, the PNA-Cas13a assay enables sensitive and specific detection of EGFR T790M mutations in ctDNA, is readily adaptable to multiple gene loci, and holds promise for clinical monitoring of tumor drug resistance.\n\nID: 42606179\nTitle: Repeated mutation of a GT92 glycosyltransferase gene confers antiviral resistance in two Caenorhabditis species.\nAbstract: Host-pathogen interactions evolve rapidly within species, providing natural genetic resources for the identification of specific ecological interaction factors. We previously identified RNA viruses that infect the nematodes C. elegans and C. briggsae in a species-specific manner. Wild strains of both host species demonstrate ample variation in viral sensitivity. Here we use recombinant inbred lines and pool-sequencing approaches to genetically map a major resistance locus in the C. elegans MY10 strain, narrowing down its position by CRISPR/Cas9 mediated recombination and testing candidates by genome editing. A rare non-synonymous polymorphism in the gtnt-1 gene, encoding a putative glycosyltransferase of the GT92 family, causes resistance to viral infection in MY10. Loss-of-function gtnt-1 alleles conferred host protection only at late developmental stages, highlighting the importance of multigenerational assays capturing the full course of viral infection and transmission. Viral resistance through gtnt-1 mutation occurred repeatedly in C. elegans, with diverse alleles each remaining at low frequency (<1%). Furthermore, leveraging closely related C. briggsae strains differing in viral susceptibility, we find that repeated loss-of-function alleles of the Cbr-gtnt-1 ortholog similarly enhanced resistance and host fitness upon infection. In conclusion, recurrent evolution in two host species of loss-of-function alleles of gtnt-1 orthologs leads to viral resistance. The gtnt-1 gene being conserved between Caenorhabditis species, these repeated inactivation events provide a case of transient ecological adaptation to a pathogen through recurrent mutation of the same gene in two species. The low population frequencies of resistant alleles point to a changing eco-evolutionary context that prevents their spread in populations.\n\nID: 42602967\nTitle: TP53 mutation drives unique transcriptional and functional vulnerabilities independent of del(17p) in multiple myeloma.\nAbstract: TP53 abnormalities contribute to treatment resistance and poor prognosis in multiple myeloma (MM), yet their functional consequences remain unclear. Here, we integrate ex vivo drug sensitivity profiling, genomics, transcriptomics, and proteomics across 167 CD138+ bone marrow patient samples to characterize TP53-associated vulnerabilities. Genome-wide CRISPR-Cas9 and RNAi screening identify vulnerabilities in TP53-mutated MM, with or without del(17p), highlighting the dependency on spindle organization, mitotic regulation, DNA synthesis, and transcriptional and metabolic regulation, but independence from MDM2. CD138+ cells with TP53 mutation exhibit increased sensitivity to chemotherapeutics, HDAC, HSP90, IGF1R, and PI3K/AKT/mTOR inhibitors as well as RNA synthesis inhibitor plicamycin, with distinct drug response profiles of MM with del(17p) and WT TP53. Our study provides new insights into refining TP53 classification to optimize treatment strategies for high-risk MM.\n\nID: 42600901\nTitle: The Bombyx mori ortholog of protein-cysteine N-palmitoyltransferase (Rasp) is essential for the development of adult organs.\nAbstract: The gap (apterous and rudimentary gonads) mutation is a spontaneous mutation that causes defects in adult organs in the silkworm Bombyx mori. Although gap larvae exhibit normal external morphology, gap mutants exhibit severe defects in adult organs, suggesting that the gap gene is required for the development of imaginal discs and the primordia of adult organs. Genetic analysis of the gap mutation provides an opportunity to understand the molecular mechanisms underlying the development of adult organs. In this study, we performed RNA-seq analysis of ovaries from gap mutants. De novo assembly of RNA-seq reads identified the insertion of a retrotransposon in the gene encoding the Bombyx ortholog of protein-cysteine N-palmitoyltransferase (Rasp), which is required for Hedgehog signaling in Drosophila. PCR and subsequent sequencing analyses revealed that an LTR transposon is inserted into exon 1 of the BmRasp gene. To verify the involvement of BmRasp in the gap phenotype, we generated a knockout allele of BmRasp (BmRaspKO) using the CRISPR/Cas9 system. Both homozygous knockout mutants and F1 pupae with the gap/BmRaspKO genotype exhibited gap-like phenotypes characterized by apterous pupa, indicating that BmRasp corresponds to the gap locus. To investigate why zygotic BmRasp expression is dispensable during embryogenesis but essential for the development of adult organs, we analyzed BmRasp expression levels in eggs and larval tissues. Furthermore, testis transplantation experiments demonstrated that BmRasp is dispensable for spermatogenesis, despite the fact that the testis exhibits the highest expression level of BmRasp among the tissues analyzed. Finally, we discuss the physiological roles of Hedgehog signaling in embryogenesis and in the development of imaginal discs in B. mori.\n\nID: 42600889\nTitle: Unlocking the Curative Potential of Gene Transfer and Editing for Hematopoietic Disorders.\nAbstract: Hematopoietic stem and progenitor cells (HSPCs) gene therapy may transform the therapeutic landscape for inherited hematological disorders and already offers potentially curative options for some diseases, including inborn errors of immunity and \u03b2-hemoglobinopathies. Its continued success relies on further refinement of gene transfer technologies, gene editing tools such as CRISPR-Cas, and optimized ex vivo HSPC manipulation protocols that ensure robust, long-term engraftment and clonal diversity with reduced-toxicity, non-genotoxic conditioning strategies. Here, we review recent developments and refinements in gene transfer and editing technologies for HSPCs, while also discussing the critical limitations and hurdles to clinical translation, as recently presented at the New Investigator Committee Gene Therapy webinar. Future directions must prioritize integrating technological innovation with the development of equitable and simplified models to reduce costs and ensure that these life-saving cellular therapies reach patients worldwide. Teaser abstract Hematopoietic stem and progenitor cells (HSPCs) gene therapy is advancing rapidly, with lentiviral gene transfer, genome editing, and emerging in vivo delivery approaches expanding the therapeutic landscape for inherited hematologic disorders. Recent clinical successes have demonstrated the potential for durable correction, while ongoing refinements continue to improve safety, efficacy, and feasibility. Key challenges remain in genotoxicity, conditioning toxicity, manufacturing scalability, and equitable global access.\n\nID: 42599816\nTitle: CRISPR RNA Engineering Enables Single Nucleotide Polymorphism Discrimination in Nucleic Acid Detection.\nAbstract: Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based diagnostic systems have emerged as powerful platforms for sensitive nucleic acid detection, yet their clinical reliability is frequently constrained by off-target activation and insufficient discrimination of closely related sequences. This review synthesizes current advances aimed at enhancing the specificity of CRISPR diagnostics, with particular emphasis on the pivotal role of CRISPR RNA (crRNA) engineering. We detail how structural determinants of crRNA, including spacer length optimization, intentional mismatch design, secondary-structure modulation, chemical modification, strand-displacement gating, and synergistic design frameworks, govern CRISPR-mediated target recognition and define the energetic and kinetic thresholds for accurate cleavage. Key engineering strategies encompassing computational prediction and modeling, high-throughput screening, and hybrid guide architectures are systematically examined for their capacity to elevate single-nucleotide discrimination, stabilize reaction performance, and enable robust multiplexed detection for pathogen profiling and mutation identification. Despite rapid progress, outstanding challenges persist, including interference from complex clinical matrices, lack of unified evaluation standards, and scalability barriers that hinder clinical translation. Addressing these limitations through integrated crRNA design, system-level optimization, and standardized benchmarking will be essential for realizing the promise of CRISPR diagnostics. Ultimately, these advances are poised to support ultrasensitive, highly specific, and portable point-of-care testing, thereby accelerating precision medicine and strengthening infectious disease surveillance and management.\n\nID: 42597777\nTitle: Replicable generation and stable maintenance of rhesus macaque iPSCs for in vitro modeling of genetic frontotemporal dementia.\nAbstract: At the Wisconsin National Primate Research Center, we have identified a family of rhesus carrying the microtubule-associated protein tau (MAPT) R406W mutation linked to frontotemporal dementia (FTD). Rhesus induced pluripotent stem cells (RhiPSCs) derived from these monkeys present a unique opportunity for in vitro modeling and comparison with cells derived from MAPT R406W human carriers. Here, we report the development of a reproducible method to generate RhiPSCs compliant with the standards of the International Society for Stem Cell Research (ISSCR) to support in vitro modeling of FTD-MAPT R406W. Our stepwise approach identified efficient methods for fibroblast derivation, fibroblast reprogramming to RhiPSC, and RhiPSC maintenance over continued culture. To derive fibroblasts from MAPT wild type (WT) and R406W monkeys, a combination of manual processing and overnight enzymatic digestion was required to maximize the number of low passage fibroblasts available for reprogramming. Fibroblast reprogramming to RhiPSC using Sendai viral vectors versus oriP/EBNA1 episomal plasmids revealed the latter as most efficient. Electroporation conditions for oriP/EBNA1 reprogramming were optimized to maximize plasmid uptake and cell survival. Ultimately, eight RhiPSC lines were derived from 4 donor rhesus monkeys (n = 2 WT, n = 2 R406W; two clonal lines per donor) and fully characterized according to ISSCR standards. RhiPSC stemness and genetic stability was best maintained on mouse embryonic fibroblast feeders in Universal Primate Pluripotency Stem Cell medium, as opposed to Essential 12 medium supplemented with IWR1, which produced cytogenetic abnormalities. Rhesus neural progenitor cells were generated using a monolayer protocol and expressed PAX6 and NESTIN after 21 days of differentiation. Our reliable method will be useful to labs seeking to derive RhiPSCs for preclinical studies. Overall, the RhiPSCs generated from MAPT R406W carriers will be a critical resource for evaluating the molecular underpinnings of tau-related neurodegeneration across primate species.\n\nID: 42597591\nTitle: Beyond chemotherapy: The rise of nucleic acid nanoformulations in personalized lung cancer therapy.\nAbstract: Lung cancer remains the leading cause of cancer-related mortality worldwide, driven by complex crosstalk among genetic, molecular, and environmental factors. Conventional treatments, including immunotherapies and targeted inhibitors, face three main challenges: tumor heterogeneity, drug resistance, and systemic toxicity. Nucleic acid therapeutics (NATs) encompass a diverse array of DNA- and RNA-based tools, including small interfering RNA (siRNA), microRNA (miRNA), messenger RNA (mRNA), antisense oligonucleotides (ASOs), and clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) systems. These tools are central to developing precision oncology approaches that operate through direct gene regulation, mutation correction, and immune system reprogramming. The clinical application of NATs currently faces three main obstacles, which include their vulnerability to enzymatic degradation, their limited ability to penetrate tissues, and their tendency to cause off-target effects. The field has progressed through the implementation of nanoformulation techniques, which utilize lipid-based polymeric and metallic carriers together with exosomes and DNA origami, and hybrid nanostructures as new platforms to enhance the stability of drugs and their cellular absorption and targeted delivery to tumors. The scientists developed functionalized nanocarriers by combining targeting ligands with materials that could respond to specific environmental changes, which allowed them to manage drug distribution and release patterns throughout the tumor microenvironment. This review focuses on establishing a direct connection between nucleic acid design and nanotechnology through an analysis of mechanistic details and progress in preclinical and clinical research, and the difficulties encountered during the progress to practical applications. The research demonstrates how artificial intelligence and bioinspired nanocarriers and multi-omics data integration create new opportunities for developing personalized adaptive nanogenetic treatment methods, which will treat lung cancer. The current advancements indicate that we are approaching a transformative era in which nanomedicine and nucleic acid therapeutics will enable safe genetic alterations of cancer through targeted therapeutic applications.\n\nID: 42595755\nTitle: Genome-wide CRISPR screening identifies cellular factors controlling nonviral genome editing efficiency.\nAbstract: To systematically map cellular factors constraining nonviral genome editing, influencing uptake and intracellular trafficking, we develop a genome-wide CRISPR screening platform linking perturbation of 19,114 genes to editing outcomes in human cells. We identify six negative regulators of delivery whose depletion increases editing efficiency by up to six-fold across diverse payloads, loci, and cell types. We test the top two factors, GJB2 and BET1L, in two distinct human models: correction of a pathogenic adenine base mutation in KCNJ13 and introduction of a cytosine base mutation in the GABAA receptor gene. Depletion of either improves base-editing outcomes by 6-fold, potentially through effects on delivery. In a patient-derived model of retinal channelopathy, knockdown of either gene improves lipid nanoparticle base editing efficiency by over 3.5-fold. This enables functional restoration of Kir7.1 ion channels in a subset of edited cells, highlighting cellular barriers as actionable targets to enhance the potency of genetic therapies.\n\nID: 42594274\nTitle: Histone H3K27M variants determine myeloid subset dependencies and immune reprogramming in diffuse midline glioma.\nAbstract: Diffuse midline gliomas (DMGs) are highly aggressive, WHO grade 4 glial tumors that arise in midline central nervous system structures and are defined by K27M mutations in histone H3 genes. These K27M mutations shape intratumoral myeloid cell composition in DMG. In H3.1K27M DMGs, genetic ablation of monocyte recruitment reshapes the tumor microenvironment (TME) by reducing monocyte-derived macrophages (MDMs) and increasing microglia and neutrophil presence, with overall survival remaining unchanged, indicating compensatory myeloid remodeling is occurring. Here, by using CRISPR/Cas9-based genome editing, we generated a mouse model deficient for CCR1/CCR2/CCR3/CCR5 (\u03941235). Using this strain, we effectively abolished monocyte and MDM infiltration and reversed compensatory recruitment of CCR1+ neutrophils. Abolishing MDMs in tumors skewed remaining neutrophils and microglia toward a homeostatic state, reduced expression of immune checkpoint molecules on T cells, and extended the survival of H3.1K27M DMG-bearing mice. In contrast, H3.3K27M DMG showed independence from MDM recruitment, suggesting reliance on other TME-driven signaling. Last, H3.1K27M DMGs exhibited reduced microglia presence and a dose-dependent increase in MDM infiltration postirradiation. MDM depletion did not further enhance radiation efficacy, potentially due to compensatory recruitment of classical neutrophils. Collectively, these data reveal histone mutation-specific myeloid dependencies in DMG, highlighting MDM-independent mechanisms in H3.3K27M tumors and MDM-dependent pathways in H3.1K27M tumors.\n\nID: 42589608\nTitle: Restoring the Balance: CRISPRa-Driven \u03b2-Tubulin Compensation as a Strategy for Tubulinopathy Treatment.\nAbstract: Microtubules are essential cytoskeletal components comprising alpha- and beta-tubulin proteins that facilitate organelle positioning, cell migration, division, and intracellular trafficking. Mutations in tubulin genes can lead to tubulinopathies, a class of rare genetic neurodevelopmental disorders characterized by a range of brain malformations and other clinical features. Recent studies have shown that pathogenic variants in beta-tubulin genes such as TUBBG308S have been found to underlie the development of ciliopathies, disorders impacting cilia, important organelles for development and cell motility. Thus, mutations in distinct tubulin genes, which present a significant hurdle for the development of therapeutic gene editing strategies and targeted therapeutics. Here, we describe the development of a mutation-independent treatment strategy based on the upregulation of non-mutated beta-tubulin isotype protein using CRISPR-Cas9 activation. By increasing the expression of various beta-tubulin proteins, we demonstrate a restoration of the microtubule network and primary cilia formation.\n\nID: 42589580\nTitle: Prime Editing Mediated Generation and Correction of the mdx5cv Mutation Restores Dystrophin Expression in Myoblasts.\nAbstract: Duchenne muscular dystrophy (DMD) is caused by mutations in the DMD gene that abolish dystrophin expression. Prime editing enables precise genome modification without generating double-strand DNA breaks or requiring donor DNA templates. We established an in vitro prime editing workflow to generate and subsequently correct the mdx5cv mutation in mouse C2C12 myoblasts. Following optimization of engineered prime editing guide RNAs (epegRNAs) and PAM-flexible prime editors, wild-type cells were edited, clonally isolated, and genotyped. Mutation correction was then evaluated using optimized epegRNA designs. Two rounds of prime editing introduced the mdx5cv mutation into approximately 20% of alleles in C2C12 cells creating the mdx5cv C2C12 cell line. Clonal isolation yielded five homozygous mutant clones among 59 expanded colonies. Optimization studies identified an epegRNA containing a 16 nucleotide reverse transcription template and a 10 nucleotide primer binding site (RTT16/PBS10) as the most efficient design. Correction of the pathogenic allele reached approximately 26%, whereas longer PBS lengths reduced editing efficiency. In silico off-target analysis using Cas-OFFinder identified no candidate genomic loci with fewer than three mismatches for the spacer sequences used in either mutation generation or correction, suggesting a favorable predicted specificity profile. Corrected mdx5cv C2C12 myoblasts retained their capacity to differentiate into multinucleated myotubes. Representative Western blot analysis detected dystrophin protein expression in differentiated corrected mdx5cv myotubes, consistent with successful correction of the pathogenic mutation. These findings establish a robust prime editing platform for both the generation and correction of the mdx5cv mutation and provide proof of concept that precise correction of the pathogenic mutation is associated with restoration of dystrophin expression following myogenic differentiation.\n\nID: 42589549\nTitle: Molecular Mechanisms Underlying Antimicrobial Resistance in Mycobacteria.\nAbstract: Antimicrobial resistance in mycobacteria arises from a complex interplay of intrinsic and acquired mechanisms that collectively limit the efficacy of current therapeutic options. Intrinsic resistance is largely driven by the low permeability of the mycobacterial cell envelope, the activity of efflux pumps, and the presence of drug-modifying enzymes, which together restrict intracellular drug accumulation and contribute to broad baseline tolerance. This review integrates resistance mechanisms of both M. tuberculosis and M. abscessus, two clinically relevant mycobacteria that share core molecular pathways while exhibiting species-specific determinants that complicate treatment. Additional intrinsic factors, including biofilm formation and stress-induced adaptive responses, further enhance persistence and reduce susceptibility to multiple drug classes. Acquired resistance predominantly results from chromosomal mutations affecting drug targets or prodrug activation pathways, such as katG, inhA, rpoB, gyrA, and pncA in Mycobacterium tuberculosis, leading to high rates of multidrug-resistant and extensively drug-resistant disease. In nontuberculous mycobacteria, species-specific determinants-including inducible macrolide resistance mediated by erm(41) in M. abscessus, plasmid-mediated erm (55) variants, rrl and rrs mutations, diverse enzymatic inactivation systems, and regulatory alterations in the MarR family that result in inducible resistance to drugs such as ethionamide -generate highly variable resistance profiles that complicate treatment. Recent advances in molecular diagnostics, including PCR-based assays, whole-genome sequencing, CRISPR-based diagnostic platforms, AI-assisted diagnostics, and emerging multi-omics approaches, have improved the detection of resistance-associated mutations and enhanced understanding of mycobacterial pathophysiology. In parallel, new therapeutic agents and optimized regimens offer promising avenues to overcome resistance, although emerging resistance to novel drugs underscores the need for continued surveillance. This review synthesizes current knowledge on the molecular basis of resistance in M. tuberculosis and NTM, highlighting implications for diagnosis, treatment, and future research.\n\nID: 42589509\nTitle: Modeling Inherited Disorders of Post-Lanosterol Cholesterol Biosynthesis: From Animal Models to Patient-Derived Stem Cells.\nAbstract: Altered post-lanosterol cholesterol biosynthesis causes a heterogeneous group of rare inherited metabolic disorders, including Smith-Lemli-Opitz syndrome, desmosterolosis, lathosterolosis, and congenital hemidysplasia with ichthyosiform nevus and limb defects syndrome. These conditions are characterized by impaired cholesterol synthesis together with the accumulation of disease-specific sterol intermediates. Current experimental and clinical evidence suggests that pathogenesis reflects both cholesterol insufficiency and sterol-mediated toxicity, including oxidative stress, perturbed developmental signaling, membrane dysfunction, and impaired neurodevelopment. Experimental models have played a central role in elucidating these mechanisms and in evaluating emerging therapeutic strategies. This review provides a comprehensive overview of currently available experimental models used to investigate inherited cholesterol biosynthesis disorders, including genetically engineered animal models, patient-derived fibroblasts, immortalized and CRISPR/Cas9-edited cell lines, and induced pluripotent stem cell-based systems. Particular emphasis is placed on Smith-Lemli-Opitz syndrome, the most extensively studied disorder within this group, while recent advances in modeling desmosterolosis, lathosterolosis, and congenital hemidysplasia with ichthyosiform nevus and limb defects syndrome are also critically discussed. We compare the strengths and limitations of each experimental platform, highlighting their contributions to understanding sterol metabolism, developmental abnormalities, and cell-type-specific disease mechanisms. Finally, we discuss current challenges and future perspectives, including the development of patient-specific induced pluripotent stem cell models, genome editing approaches, and next-generation multicellular systems. Collectively, this review provides an updated framework for selecting appropriate experimental models to investigate cholesterol biosynthesis disorders and accelerate the development of mechanism-based therapeutic strategies.\n\nID: 42587136\nTitle: Mechanistic machine learning for prediction of prime editing outcomes.\nAbstract: Prime editing (PE) can make specific local changes to genomic DNA in living systems but its efficient application currently requires extensive optimization of PE guide RNA (pegRNA) sequences. Here we present OptiPrime, a machine learning model of PE efficiency based on current understanding of PE mechanisms. OptiPrime achieves state-of-the-art accuracy on PE efficiency prediction and enables prediction of nicking guide RNA (PE3) and dual pegRNA (twinPE) outcomes. We validate that OptiPrime has learned the determinants of mammalian mismatch repair (MMR) and is well suited for nominating MMR-evasive silent edits that improve PE efficiency. We demonstrate the use of OptiPrime in a variety of prospective therapeutic contexts in primary human and mouse cells. Lastly, we show that OptiPrime can be used to achieve streamlined and efficient in vivo correction of a pathogenic mutation in the brain of a mouse model of KIF1A-associated neurological disorder. We provide a webserver for OptiPrime ( https://optipri.me/ ) as a community resource.\n\nID: 42630431\nTitle: Direct neuronal reprogramming for neurological diseases: applications, translational Challenges, and future directions.\nAbstract: Neurological diseases, often caused by irreversible loss of terminally differentiated neurons, present considerable challenges to treatment due to the limited regenerative capacity of these neurons. Although induced pluripotent stem cells hold promise for neuronal regeneration, their clinical application is constrained by risks, including tumorigenicity, incomplete neuronal maturation, and immune rejection. Recent advancements in direct neuronal reprogramming, which bypasses the intermediate pluripotent stage by directly converting non-neuronal cells into functional neurons, offer a compelling alternative for in situ neuronal replacement in neurodegenerative diseases. Key transcription factors, such as NeuroD1, Ascl1, Sox2, as well as CRISPR activation (CRISPRa) of NGN2 and ISL1, have been explored to convert glial cells into neurons. However, several challenges remain. This review discusses the current applications of direct neuronal reprogramming technology in several neurological diseases. We further highlight the potential contamination issues in adeno-associated virus (AAV) delivery systems and propose a code of conduct to avoid artifacts and pitfalls. Finally, we point out future directions for expanding direct reprogramming targets, integrating organoid-based disease modeling, and advancing reprogramming regulation techniques.\n\nID: 42612101\nTitle: Generation of GABAergic Neurons from Human Induced Pluripotent Stem Cells Using Doxycycline-Inducible ASCL1/DLX2 Expression at AAVS1.\nAbstract: Human induced pluripotent stem cells (hiPSCs) offer an unprecedented opportunity to model human neurological diseases in vitro. Reliable generation of defined neuronal populations, such as gamma-aminobutyric acid (GABAergic) neurons, is essential for these studies. This protocol details a robust method for differentiating hiPSCs into GABAergic neurons using a doxycycline-inducible system. The approach relies on the stable integration of transgenes encoding the transcription factors ASCL1 and DLX2 into the safe-harbor adeno-associated virus integration site 1 (AAVS1.) locus via CRISPR/Cas9-mediated knock-in. This targeted integration avoids the transgene silencing often observed with random lentiviral integration. The protocol covers the maintenance of hiPSCs, the nucleofection process for transgene integration, puromycin selection to enrich successfully engineered cells, and the step-by-step differentiation procedure. Upon induction with doxycycline, the engineered hiPSCs rapidly exit the cell cycle, acquire neuronal morphology, and express GABAergic lineage markers within 21 days. Key steps include neuro-induction and subsequent maturation using specific growth factors, as well as potential approaches to improve cellular adhesion during maturation. This standardized method yields enriched populations of induced neurons expressing GABAergic lineage markers, providing a valuable tool for neuroscience research and cellular modeling.\n\nID: 42610637\nTitle: Assembly and Maintenance of Myofibrils in the Heart.\nAbstract: The assembly of actin and myosin to the paracrystalline arrangement of myofibrils in striated muscle, that is, heart and skeletal, has puzzled many a cell biologist. Different models, based on cultured cardiomyocytes, were proposed for the last 30\u2009years to explain the sequence of events. These were then evaluated during heart development in embryos in\u00a0situ and more recently in cardiomyocytes that were derived from human induced pluripotent stem cells (iPSC-CMs). A lot of the initial work was quite descriptive but recent advances in gene editing technology and in super resolution microscopy allow a more targeted functional analysis and will give unprecedented insight. This review will discuss the general principles of myofibril assembly in the heart and cover new findings on myofibril maintenance and turnover.\n\nID: 42603820\nTitle: Neurabin I haploinsufficiency disrupts ion channel regulation and synaptic maturation in human cortical neurons in neurodevelopmental disorders.\nAbstract: Heterozygous loss-of-function variants in Neurabin I (PPP1R9A), responsible for encoding a cytoskeletal scaffolding protein essential for synaptic plasticity, are recurrently associated with neurodevelopmental and neuropsychiatric disorders, yet their direct effects on human neuronal maturation remain unclear. Here, we establish the first comprehensive human mechanistic model of PPP1R9A haploinsufficiency using an isogenic CRISPR/Cas9-engineered iPSC system differentiated into cortical neurons to define dosage-dependent functional consequences. PPP1R9A+/- neurons exhibited pronounced hyperspinogenesis and increased neuritic complexity, indicative of aberrant structural maturation; however, whole-cell patch-clamp recordings revealed impaired intrinsic excitability, including reduced action potential firing, altered waveform properties, and defective axo-somatic coupling, uncovering a striking dissociation between neuronal morphology and function. Long-read single-cell transcriptomics and quantitative proteomics identified coordinated downregulation of ion channel and synaptic transmission pathways, including genes essential for sodium channel function and glutamatergic signaling, together with disruption of synaptic vesicle cycling, axon guidance, and neurodevelopmental programs. Pseudotime trajectory analysis further demonstrated delayed neuronal differentiation, with mutant neurons accumulating at intermediate developmental states rather than acquiring mature cortical identities. Importantly, molecular rescue experiments confirmed causality, as restoration of full-length PPP1R9A expression robustly normalized transcriptional and synaptic signaling programs, whereas allele-specific antisense oligonucleotide-mediated suppression of the mutant transcript achieved only partial rescue. Taken together, these findings establish PPP1R9A haploinsufficiency as a driver of impaired molecular, electrophysiological, and developmental maturation in human cortical neurons, providing a human-specific mechanistic framework linking reduced Neurabin I dosage to neurodevelopmental and psychiatric disease risk.\n\nID: 42589126\nTitle: Cell-Based Therapies for Cardiac and Vascular Regeneration in Cardiovascular Disease: Recent Advances, Translational Barriers, and Future Directions.\nAbstract: Cardiovascular diseases (CVDs) remain the foremost cause of death globally, responsible for 19.2 million deaths and 437 million disability-adjusted life years in 2023, with prevalent cases having more than doubled since 1990. No approved therapy restores myocardium lost to infarction. The adult heart replaces cardiomyocytes at approximately 1% per year in young adults, declining to about 0.45% per year with ageing, far below what is needed to recover the more than one billion cells destroyed by a large myocardial infarction. Cell-based regenerative strategies have been investigated for more than two decades, encompassing bone marrow mononuclear cells (BM-MNCs), mesenchymal stromal cells (MSCs), cardiac progenitor cells, cardiosphere-derived cells (CDCs), skeletal myoblasts, and induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs). Safety has been consistent. Efficacy has been modest and variable: the CADUCEUS trial demonstrated scar mass reduction with CDCs without proportionate ejection fraction improvement; the Phase 1/2 POSEIDON trial confirmed MSC safety in 30 patients; and the Phase 3 DREAM-HF trial, enrolling 537 patients, failed its primary endpoint (HR 1.2, p = 0.406). Mechanistic work has established that transplanted cells engraft poorly and exert their benefit principally through paracrine signalling mediated by secreted extracellular vesicles and exosomes carrying microRNAs, trophic factors, and immunomodulatory proteins. For iPSC-CMs, electrophysiological immaturity and arrhythmogenic risk in primate models remain unresolved barriers. Emerging strategies include CRISPR-engineered hypoimmune iPSC lines, bioengineered cardiac patches, injectable hydrogel scaffolds, and engineered exosome platforms. This review provides a comprehensive synthesis of preclinical and clinical evidence, examines translational barriers, and identifies the scientific and regulatory priorities required before these therapies can enter routine clinical practice.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

In combination with induced pluripotent stem cell (hiPSC) reprogramming, in vitro gametogenesis provides an avenue for patient-specific disease modeling approaches. However, further advancements are required, as current protocols are limited to early stages of germ cell development. To get one step closer to this goal, here we aimed to identify optimal conditions for generating high-quality hiPSC lines capable of in vitro germ cell differentiation. We isolated two clinically available somatic cell types, peripheral blood-derived mononuclear cells and cumulus cells from the same female donor, and reprogrammed them into human induced pluripotent stem cells (hiPSCs). We then assessed their differentiation into ectoderm, mesoderm, and endoderm, and evaluated their X-chromosome inactivation status, a critical indicator of stem cell quality. Finally, we compared the capacity of PBMC- and cumulus-derived hiPSCs to differentiate into human primordial germ cell-like cells (hPGCLCs). We found that despite variability between cell lines, hiPSCs from both cell types were capable of generating hPGCLCs and that variations in X-chromosome state did not appear to generally interfere with the process. Our findings provide insight into germ cell differentiation from different clinically available starting materials guiding future patient-specific studies of fertility disorders.\n --- END ACTUAL ABSTRACT FOR 42113606 ---\n\n- ERROR: You cited ID: 42513228 for the quote: \"Treatment options for localized breast cancer continue to include surgery ... combined with systemic therapies tailored to tumor biology\"\n FACT: Ellipses (...) are strictly forbidden.

Patients may present with either localized or advanced disease, with clinical outcomes increasingly influenced by molecular subtype and genetic profile. This review highlights the key genetic factors involved in breast cancer, current diagnostic and therapeutic strategies, and promising emerging approaches that may shape future clinical management. Breast cancer diagnosis typically involves clinical breast examination, imaging techniques such as mammography and ultrasound, and confirmatory biopsies. Genetic mutations in specific genes are strongly linked to the development, progression, and metastasis of the disease. Treatment options for localized breast cancer continue to include surgery (lumpectomy or mastectomy) and radiotherapy, combined with systemic therapies tailored to tumor biology, such as endocrine therapy, human epidermal growth factor receptor 2 (HER2)-targeted therapy, and cyclin-dependent kinase (CDK)4/6 inhibitors. For advanced or metastatic breast cancer, recent therapeutic advances include the use of immunotherapy (e.g., immune checkpoint inhibitors), Poly (ADP-ribose) polymerase (PARP) inhibitors for Breast Cancer gene (BRCA)-mutated cancers, antibody-drug conjugates, and novel targeted agents, which have significantly improved patient outcomes in selected populations. Recent findings in breast cancer genetics have highlighted the critical role of germline and somatic mutations, particularly in genes such as BRCA1, BRCA2, phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), and TP53, in driving tumor initiation, progression, and therapeutic response. Molecular profiling and next-generation sequencing technologies have enabled more precise tumor classification and facilitated the development of personalized treatment strategies. Despite these advances, treatment resistance and disease recurrence remain major challenges, particularly in aggressive subtypes such as triple-negative breast cancer. Consequently, ongoing research is exploring alternative and complementary approaches, including nanotechnology-based drug delivery systems, gene editing techniques such as clustered regularly interspaced short palindromic repeats-Cas9 (CRISPR-associated protein 9) (CRISPR-Cas9), cancer vaccines, and the integration of traditional and plant-derived compounds. These strategies aim to enhance therapeutic efficacy, reduce systemic toxicity, and overcome resistance mechanisms.\n --- END ACTUAL ABSTRACT FOR 42513228 ---\n\n- ERROR: You cited ID: 42630431 for the quote: \"Direct neuronal reprogramming ... offer a compelling alternative for in situ neuronal replacement in neurodegenerative diseases.\"\n FACT: Ellipses (...) are strictly forbidden.

Although induced pluripotent stem cells hold promise for neuronal regeneration, their clinical application is constrained by risks, including tumorigenicity, incomplete neuronal maturation, and immune rejection. Recent advancements in direct neuronal reprogramming, which bypasses the intermediate pluripotent stage by directly converting non-neuronal cells into functional neurons, offer a compelling alternative for in situ neuronal replacement in neurodegenerative diseases. Key transcription factors, such as NeuroD1, Ascl1, Sox2, as well as CRISPR activation (CRISPRa) of NGN2 and ISL1, have been explored to convert glial cells into neurons. However, several challenges remain. This review discusses the current applications of direct neuronal reprogramming technology in several neurological diseases. We further highlight the potential contamination issues in adeno-associated virus (AAV) delivery systems and propose a code of conduct to avoid artifacts and pitfalls. Finally, we point out future directions for expanding direct reprogramming targets, integrating organoid-based disease modeling, and advancing reprogramming regulation techniques.\n --- END ACTUAL ABSTRACT FOR 42630431 ---\n\n- ERROR: You cited ID: 42597591 for the quote: \"Nucleic acid therapeutics (NATs) encompass a diverse array of DNA- and RNA-based tools ... central to developing precision oncology approaches that operate through direct gene regulation, mutation correction, and immune system reprogramming.\"\n FACT: Ellipses (...) are strictly forbidden.

Conventional treatments, including immunotherapies and targeted inhibitors, face three main challenges: tumor heterogeneity, drug resistance, and systemic toxicity. Nucleic acid therapeutics (NATs) encompass a diverse array of DNA- and RNA-based tools, including small interfering RNA (siRNA), microRNA (miRNA), messenger RNA (mRNA), antisense oligonucleotides (ASOs), and clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) systems. These tools are central to developing precision oncology approaches that operate through direct gene regulation, mutation correction, and immune system reprogramming. The clinical application of NATs currently faces three main obstacles, which include their vulnerability to enzymatic degradation, their limited ability to penetrate tissues, and their tendency to cause off-target effects. The field has progressed through the implementation of nanoformulation techniques, which utilize lipid-based polymeric and metallic carriers together with exosomes and DNA origami, and hybrid nanostructures as new platforms to enhance the stability of drugs and their cellular absorption and targeted delivery to tumors. The scientists developed functionalized nanocarriers by combining targeting ligands with materials that could respond to specific environmental changes, which allowed them to manage drug distribution and release patterns throughout the tumor microenvironment. This review focuses on establishing a direct connection between nucleic acid design and nanotechnology through an analysis of mechanistic details and progress in preclinical and clinical research, and the difficulties encountered during the progress to practical applications. The research demonstrates how artificial intelligence and bioinspired nanocarriers and multi-omics data integration create new opportunities for developing personalized adaptive nanogenetic treatment methods, which will treat lung cancer. The current advancements indicate that we are approaching a transformative era in which nanomedicine and nucleic acid therapeutics will enable safe genetic alterations of cancer through targeted therapeutic applications.\n --- END ACTUAL ABSTRACT FOR 42597591 ---\n\n- ERROR: You cited ID: 42626030 for the quote: \"experimentally, ARPC1A knockdown increased cisplatin sensitivity, promoted cisplatin-induced apoptosis, and suppressed migration and invasion.\"\n FACT: Strict Misquote Detected!

We integrated single-cell RNA sequencing, epithelial CNV-like inference, fibroblast reclustering, CellChat analysis, signature scoring, hdWGCNA, CAF-epithelial coupling, exploratory GSE14209 evaluation, TCGA-STAD mutation/copy-number contextualization, and DepMap CRISPR virtual knockout analysis, followed by experimental validation in AGS and HGC-27 cells. IGF1+ CXCL12+ CAFs showed resistance-supportive stromal features, and CAF-epithelial coupling prioritized ARPC1A as a tumor epithelial candidate associated with this stromal program. In TCGA-STAD, ARPC1A mutations were rare and consisted of three missense and two frameshift variants without a recurrent hotspot; the mutant tumors were confined to the MSI subtype and showed an immune-activated, high TMB/MSI context, indicating mutation-immune crosstalk rather than a clear mutation-specific CAF, EMT, drug resistance, or cisplatin response phenotype. By contrast, ARPC1A copy-number gain/amplification was more frequent and tracked with ARPC1A expression, CIN enrichment, aneuploidy, and fraction of genome altered. DepMap CRISPR data indicated mostly weak-to-mild baseline ARPC1A dependency in upper GI and gastric/GEJ models. Experimentally, ARPC1A knockdown increased cisplatin sensitivity, promoted cisplatin-induced apoptosis, and suppressed migration and invasion. These findings identify a CAF-associated ARPC1A epithelial program linked to cisplatin response and support a mutation-immune/copy-number framework in which ARPC1A is interpreted mainly through immune-contextual mutation patterns and expression dosage rather than recurrent gain-of-function mutation.\n --- END ACTUAL ABSTRACT FOR 42626030 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n-

Current literature confirms the feasibility of CRISPR correction in hematological progenitors and the specification of primordial germ cell-like cells (hPGCLCs) from hiPSCs. However, the translation of these combined technologies into a multi-generational curative strategy for human sickle cell disease remains speculative, constrained by bioethical regulations and the technical requirement for further validation of long-term germline maturation and safety.\n\n### [INTRODUCTION & JUSTIFICATION]\nGene therapy for \u03b2-haemoglobinopathies is based mainly on two strategies: gene addition and gene editing. A technological landmark was achieved when the Food and Drug Administration (FDA) approved the first CRISPR-based gene therapy (exa-cel) to edit erythroid specific enhancer region of BCL11A in hematopoietic stem cells. While this current standard of care provides durable remission for somatic patients, it does not address the hereditary transmission of the HBB mutation. The integration of iPSC technologies suggests an avenue for future germline-level interventions. As noted, one of the first embryonic lineages to be specified in the human embryo is the germ cell lineage, marked by the induction of the primordial germ cells (PGCs). Recent advancements have led to the development of defined protocols that mimic early embryonic development and allow the specification of transcriptomically and epigenetically validated human primordial germ cell-like cells (hPGCLCs). This provides a foundational mechanism for potentially generating germlines. Furthermore, researchers have demonstrated that these results establish a scalable strategy for generating fetal granulosa-like supporting cells from hiPSCs and provide an effective and multi-generational safety framework for oocyte-contact IVM interventions. Although advancements in scientific research, especially gene editing and in-vitro gametogenesis (IVG), are not yet fully applicable, their potential future use appears to pose significant bioethical questions. The gap remains between current somatic gene editing, which is clinically validated for SCD, and the prospect of germline replacement, which lacks clinical authorization and human-validation data.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Current curative gene therapies for SCD (e.g., exa-cel) function through hematopoietic stem cell editing, not germline alteration.\n* CRISPR-mediated editing has been successfully applied to produce humanized DMD mouse models with clinical sequence specificity.\n* The use of ovarian support cells (OSCs) derived from hiPSCs has been shown to improve in vitro maturation outcomes, providing a potential helper-cell platform for gametogenesis.\n* Studies have successfully utilized CRISPR to ablate genes in chicken PGCs, demonstrating that germline-restricted suicide-gene cassettes can generate sterile surrogate hosts.\n* The \"14-day rule\" and other regulatory frameworks significantly limit the current translation of embryological research into clinical reproductive medicine.\n* Synthesis errors in ssODNs are a source of untoward variation in HDR-mediated gene editing, emphasizing the need for rigorous quality control beyond current standards.\n* Porcine expanded potential stem cells (pEPSCs) represent a versatile platform for multiplex genome editing, showing that stem cells can maintain genetic stability through multiple edits.\n* Mechanistic links exist between APP dosage and Notch signaling in iPSC-derived neural models, highlighting that gene dosage effects must be considered alongside mutation correction.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Herein, we made a G16D mutation in the \u03b3-globin gene to generate the G16D mutation (GbGM) LV to increase fetal hemoglobin formation. We also generated an insulated version of this LV, GbGMI, inserting a 36-bp insulator from the Foamy virus in the long terminal repeats of the LV. Preclinical batches of GbGM and GbGMI LV showed both were highly efficacious in correcting SCA in mice, with sustained gene transfer in primary transplanted SCA mice and high hematopoietic stem cell (HSC) transduction in colony-forming unit-spleen in secondary transplanted mice. CRISPR-mediated targeting of the proviruses into the LMO2 proto-oncogene showed remarkably reduced LMO2 activation by both insulated and uninsulated LV, compared to the SFFV \u03b3-RV vector targeted to the same locus. We therefore used the GbGM LV to perform preclinical human CD34+ gene transfer. We assessed gene transfer and engraftment of human HSCs in two immunocompromised mouse models: persistent stable GbGM-transduced cell engraftment was comparable to that of untransduced cells with no detrimental effects on hematopoiesis up to 20\u00a0weeks post transplant. These robust preclinical studies in mouse and human HSCs allowed its translation into a clinical trial.",
"40213215": "ID: 40213215\nTitle: Managing emotional and physical stress in sickle cell anemia: a review of effective strategies and approaches.\nAbstract: Sickle cell anemia (SCA) is a genetic blood disorder characterized by recurrent pain episodes, chronic complications, and significant emotional and physical stress. This review article explores effective strategies for managing both the emotional and physical aspects of stress in SCA patients. A comprehensive literature search was conducted across multiple databases, including PubMed, Scopus, and Google Scholar, using keywords such as \"sickle cell anemia\", \"stress management\", \"psychological support\", and \"pain management\". Emotional stress in SCA arises from chronic pain, frequent hospitalizations, and disease uncertainty, leading to conditions such as anxiety and depression. Effective management of emotional stress involves a combination of psychological counseling, cognitive-behavioral therapy (CBT), and support groups, which help patients develop coping strategies and address the mental health challenges of living with a chronic illness. This review evaluates various psychological interventions and their impact on patient outcomes, emphasizing the need for integrated mental health support in the management of SCA. Physical stress in SCA is primarily due to acute vaso-occlusive crises and chronic pain, which require effective pain management and preventive measures. The review explores pharmacological treatments, such as opioids and hydroxyurea, as well as nonpharmacological approaches, including physical therapy and lifestyle modifications. Additionally, the article discusses innovative therapies like gene therapy and stem cell transplantation, which hold promise for long-term disease management.",
"40238672": "ID: 40238672\nTitle: Evaluating the long-term benefits of hydroxyurea in pediatric sickle cell anemia.\nAbstract: Hydroxyurea is the primary disease-modifying medication for sickle cell anemia (SCA), but its long-term effects, particularly how these effects change over time, are not well understood. This study aimed to quantify the effects of hydroxyurea on clinical and laboratory outcomes in children with SCA over a prolonged period of use. We conducted a quasi-experimental study using contemporary difference-in-differences and dynamic event study analyses on a longitudinal cohort of 2147 children with SCA (hemoglobin SS or hemoglobin SS\u03b20, HbSS/HbS\u03b20) from 2010 to 2021. The primary outcomes included emergency department (ED) visits per year, hospital days per year, and annual average hemoglobin concentration. Hydroxyurea use was associated with fewer ED visits per year (average treatment effect on the treated [ATT], -0.36 visit per year; 95% confidence interval [CI], -0.57 to -0.16) and fewer hospital days per year (ATT, -0.84 d/y; 95% CI, -1.51 to -0.17) with sustained effects over time. On average, the hemoglobin concentration increased with hydroxyurea use (ATT, 0.56 g/dL; 95% CI, 0.39-0.73), but the sustained effect was observed only among the subgroup with laboratory markers of good adherence. This study demonstrates that hydroxyurea has sustained clinical benefits in reducing ED visits and hospital days across years of use in children with SCA. These findings provide perspective for clinicians and families regarding the long-term efficacy of hydroxyurea in pediatric SCA management and underscore the importance of ongoing adherence counseling to optimize clinical benefit. Furthermore, this study design provides a methodological framework for rigorously and causally evaluating other SCA-specific treatments, such as stem cell transplant and gene therapy, in real-world settings.",

We estimate that standard-of-care GT for an adult with SCD will require an average of 35-45\u2009units of red blood cells over a 6-month period. Institutions should actively plan for these transfusion needs and share information to inform national consensus policies on the management of alloimmunization during GT.",

"40699667": "ID: 40699667\nTitle: Advances in Gene Therapy with Oncolytic Viruses and CAR-T Cells and Therapy-Related Groups.\nAbstract: Cancer gene therapy is attracting considerable attention as a new treatment method for overcoming intractable cancers. CAR-T cell therapy has already achieved remarkable results, particularly for hematological tumors. Because CAR-T cells can increase within the body, they have the advantage of requiring only a single administration. In addition, CAR-T cell therapy targeting the CD19 antigen has been established for relapsed or refractory disease in young people with CD19-positive acute B-cell leukemia (B-acute lymphoblastic leukemia, B-ALL) and diffuse large B-cell lymphoma (DLBCL). In addition to CAR-T cell therapy, oncolytic viruses represent a promising approach for cancer treatment, with some already in clinical use and others being researched for their potential benefits. These viruses infect and kill cancer cells, triggering an immune response that helps the body recognize and fight cancer. Oncolytic virus therapy is a form of immunotherapy that uses modified viruses to target and destroy tumor cells while potentially stimulating antitumor immune responses. These viruses have shown promising activity in clinical trials, with some approved for specific cancers like melanoma. Research is ongoing to improve their efficacy, expand their use to other cancer types, and overcome the logistical challenges associated with their delivery. Gene therapy can potentially treat diseases caused by recessive gene disorders like cystic fibrosis, hemophilia, muscular dystrophy, and sickle cell anemia, as well as acquired genetic diseases, such as cancer and viral infections like acquired immunodeficiency syndrome (AIDS).",
"40834880": "ID: 40834880\nTitle: Gene therapy for HbSC disease and other compound heterozygous sickle hemoglobinopathies: a time for inclusion.\nAbstract: Two gene therapy products have been approved by the US Food and Drug Administration for sickle cell disease. Nearly all patients in the clinical trials that led to approval either were sickle hemoglobin (HbS) gene homozygotes (sickle cell anemia) or had HbS-\u03b20 thalassemia. HbSC disease, caused by compound heterozygosity for HbS and hemoglobin C genes, is the second most common genotype of sickle cell disease. Gene therapy has not been tested in patients with HbSC disease who are severely symptomatic. We discuss the pathophysiology and clinical features of HbSC disease and how gene therapy is likely to provide a curative option for some individuals. We also discuss the mechanism through which fetal hemoglobin (HbF) and HbF-like HbA (HbAT87Q) might mitigate adverse clinical outcomes and end-organ damage in patients with HbSC disease and other compound heterozygous sickle hemoglobinopathies.",
"41072772": "ID: 41072772\nTitle: Acute Toxicities of Bone Marrow Donation in Unrelated Donors with Sickle Cell Trait: A Center for International Blood and Marrow Transplantation Research Analysis.\nAbstract: Ethnic minority donors are essential in international donor registries to ensure access to all patients requiring allogeneic stem cell transplantation. Current literature regarding bone marrow (BM) donation-associated pain and toxicity in donors with sickle cell trait (ST), a condition that disproportionally affects minorities, is very limited. Improved communication with potential donors with ST about donation-associated toxicities is important to address misconceptions about donation and may increase the likelihood of participation by minority donors. The aim of this study was to determine the impact of ST on pericollection pain and toxicities experienced by unrelated BM donors. The study population comprised first-time unrelated donors with ST and a subset of unrelated donors without ST from the United States whose BM donation was facilitated by the National Marrow Donor Program (NMDP) between 2010 and 2019. Donors in the control group (ie, donors without ST) were selected for propensity score matching based on age categories, sex, race/ethnicity, and predonation skeletal pain. Logistic regression models were conducted to compare the donors with and without ST for pain and toxicities associated with donation after adjusting for differences in donor characteristics. Descriptive statistics were used to report serious adverse events. Univariate probabilities of complete recovery from donation were calculated using the Kaplan-Meier estimator. A total of 346 BM donors (87 with ST and 259 without ST) were included in this study. The majority of the donors in both cohorts were male (52%), African American (64%) and overweight or obese (77%). Stem cell collection parameters, including BM harvest volume, requirement for autologous blood transfusion postharvest, and duration of anesthesia were comparable between the 2 cohorts. At 2 days postdonation, 68.9% of BM donors with ST and 83.1% of BM donors without ST experienced skeletal pain (P < .01). Although grade 1 pain was more common in donors without ST (51.4% vs 35.6%), grade 2-4 pain was comparable between the 2 cohorts (P = .98). At 1 month postdonation, the incidence of grade 2-4 pain was also comparable between the 2 cohorts (P = .25). By 6 months postdonation, the rates of persistent pain were low, at 5.7% in donors with ST and 6.5% in donors without ST. Donation-related modified toxicity criteria (MTC) at 2 days postdonation were comparable between the 2 cohorts (P = .59). The median time to recovery was 23.5 days in donors with ST and 22.0 days in donors without ST. The rate of reported AEs was slightly higher in donors with ST (2.29% versus 1.59%). BM donation appeared to be well tolerated in donors with ST, with similar rates of postdonation pain and general symptoms as seen in donors without ST. Moreover, BM donation carries a low risk of perioperative mortality, comparable to that observed in donors without ST. This report provides, to our knowledge, the first comprehensive analysis of the impact of ST on toxicities and recovery after BM donation and adds to our understanding of the safety of BM donation in donors with ST.",
"41220897": "ID: 41220897\nTitle: Emerging Gene Therapies in Sickle Cell Disease: A Comparative Review of Efficacy and Safety Against Standard Treatments.\nAbstract: Sickle cell disease (SCD) is an inherited haemoglobinopathy caused by a point mutation in the \u03b2-globin gene, resulting in abnormal sickle haemoglobin (HbS) and variable clinical expression ranging from mild to severe. While individuals with sickle cell trait are usually asymptomatic, those with homozygous disease may experience chronic haemolytic anaemia, recurrent vaso-occlusive crises, and progressive organ injury. Current standards of care, including hydroxyurea therapy, chronic blood transfusions, and allogeneic haematopoietic stem cell transplantation (HSCT), have substantially improved survival and reduced complications. However, each approach has limitations, such as incomplete disease control, toxicity, and limited donor availability. Recent advances in non-myeloablative and haploidentical HSCT have expanded curative options, achieving high survival with minimal graft-versus-host disease, though accessibility and cost remain challenges. Emerging gene therapies, particularly lentiviral vector-mediated gene addition and CRISPR-Cas9 genome editing, represent major progress by directly targeting the underlying genetic defect. These autologous approaches eliminate donor-related immune risks and have demonstrated durable haemoglobin correction, near-complete resolution of vaso-occlusive events, and encouraging outcomes in stroke prevention. This review synthesises evidence comparing gene therapies with standard treatments, outlining molecular mechanisms, efficacy, safety, and long-term considerations. Key challenges include stem-cell mobilisation, fertility preservation, conditioning toxicity, and equitable access. Early trials show substantial clinical benefit, improved quality of life, and favourable safety profiles. Emerging in vivo editing technologies may further simplify delivery and enhance global accessibility. Integrating gene therapy into evolving standards of care could transform SCD management, offering realistic prospects for durable remission or cure.",
"41416641": "ID: 41416641\nTitle: The road to restore male fertility using in vitro-derived germ cells.\nAbstract: Human-induced pluripotent stem cells (hiPSCs) offer immense potential in reproductive medicine, particularly for males who lack germ cells and cannot achieve biological parenthood through conventional ARTs. Early efforts to derive human germ cells from stem cells were hindered by low efficiency, subpar characterization, and the lack of standardized differentiation approaches. However, recent advancements have led to the development of defined protocols that mimic early embryonic development and allow the specification of transcriptomically and epigenetically validated human primordial germ cell-like cells (hPGCLCs). Current research focuses on maturing hPGCLCs in vitro, particularly within 3D culture systems that resemble their physiological microenvironment, with the aim of producing transplantable hiPSC-derived spermatogonial stem cells (SSCs) or differentiating them to sperm. At the same time, researchers are also testing whether hiPSCs generated from infertile patients can resume germline differentiation. This narrative review aimed to summarize the key efforts and remaining challenges in differentiating male germ cells from human pluripotent stem cells (hPSCs), with a particular focus on defined and validated protocols for hPGCLC specification. In parallel, we addressed key safety and ethical considerations that must be accounted for the development of clinical applications. A deeper understanding of the approaching therapeutic use of hiPSCs in reproductive medicine is essential for developing novel regenerative fertility strategies. PubMed, Scopus, and Web of Science were searched for studies attempting germ cell differentiation from hPSCs using relevant keywords ('stem cells', 'human pluripotent stem cells', 'human embryonic stem cells', 'human induced pluripotent stem cells', 'somatic cell reprogramming', 'infertility', 'germline', 'spermatogenesis', 'germ cells', and 'primordial germ cells'). No time period restriction was established. Studies with an exclusive focus on female germline differentiation were excluded. To maintain a human-focused perspective, only key animal studies are presented. The literature reveals a clear segregation among protocols for deriving germ cells from hPSCs, particularly between earlier studies lacking standardized differentiation conditions and characterization, and the most recent, defined protocols having transcriptomic and epigenetic validation against in vivo hPGCs. Moreover, during the last decade, the field has seen remarkable progress, with multiple efforts aimed at maturing hPGCLCs, closely recapitulating late male embryonic germline development. Additionally, hiPSCs derived from male patients at risk of infertility, particularly those without underlying genetic syndromes, generally retain the capacity for early germline commitment. While attempts at maturating patient germ cells beyond the hPGCLC state remain limited, the rapid pace of discovery and refinement in recent years suggests that further breakthroughs, including clinically applicable fertility restoration strategies, are likely to be achieved in the near future. The ability to generate hiPSCs from infertile patients and to specify them into hPGCLCs supports the feasibility of obtaining hiPSC-derived SSCs for future therapeutic use. These advances raise important ethical, regulatory, and societal questions that must be actively discussed among researchers, clinicians, policymakers, and the general public to ensure responsible and equitable access to these technologies.

"41419637": "ID: 41419637\nTitle: CRISPR screens in human neural organoids and assembloids.\nAbstract: Studying the molecular mechanisms underlying the assembly of the human nervous system remains a significant challenge. The ability to generate neural cells from pluripotent stem cells, combined with advanced genome-editing techniques, provides unprecedented opportunities to uncover the biology of human neurodevelopment and disease. Organoids and assembloids enable the in vitro modeling of previously inaccessible developmental processes, such as the specification and migration of human neurons, including the integration of cortical interneurons from the ventral into the dorsal forebrain. Here, we present a detailed protocol that combines pooled CRISPR-Cas9 screening with neural organoid and assembloid models and illustrate how it can be applied to map hundreds of disease genes onto cellular pathways and specific aspects of human neural development. Our protocol outlines key steps, from planning and optimizing genetic perturbations to designing readouts for neuronal generation and migration, conducting the screening and validating candidate genes. The screening experiments take ~3 months to complete and require expertise in stem cell culture and neural differentiation, genetic engineering of human induced pluripotent stem cell lines, fluorescence-activated cell sorting and next-generation sequencing and analyses. The integration of genetic screening and human cellular models constitutes a powerful platform for investigating the mechanisms of human brain development and disease, paving the way for the discovery of novel therapeutics.",
"41462929": "ID: 41462929\nTitle: Atrazine Induces Reproductive Toxicity in an In Vitro Spermatogenesis (IVS) Model.\nAbstract: Background/Objectives: Atrazine (ATZ) is a widely used herbicide, and most studies of its reproductive toxicity have been conducted in vivo using animal models, where ATZ disrupts redox homeostasis, leading to male reproductive dysfunction. However, its molecular mechanisms of action in human spermatogenic cells remain poorly understood. Huntington's disease (HD), an autosomal dominant disorder caused by abnormal CAG repeat expansion in the HTT gene, exhibits heightened oxidative stress sensitivity and mitochondrial dysfunction, which may further impair reproductive function. This study investigated ATZ effects on human spermatogenesis using an in vitro spermatogenesis (IVS) model derived from human induced pluripotent stem cells (hiPSCs), focusing on Nrf2-mediated oxidative responses and apoptotic regulation during spermatogonial stem cell-like cell (SSCLC) differentiation in wild-type (WT) and HD hiPSC lines. Methods: Two WT and two HD hiPSC lines carrying 44 (HD1) and 180 (HD2) CAG repeats were treated with ATZ (0, 0.01, 1, or 10 \u03bcM) for 30 days, followed by differentiation into SSCLCs for 15 days under continuous exposure. Expression of pluripotency (OCT4, SOX2), oxidative stress (NFE2L2, SOD1, GPX1, NQO1), cell cycle (CDK1), apoptosis (BCL2, BAX, CASP3, CASP9, FAS, FASLG), and spermatogenic markers (DAZL, ZBTB16, GFRA1, PIWIL2) were assessed by immunocytochemistry and qRT-PCR. Results: Long-term ATZ exposure affected pluripotency markers in hiPSCs and SSCLC differentiation in a cell line-dependent manner. WT cells exhibited early differentiation suppression without significant apoptosis. HD1 cells were highly sensitive: low ATZ doses (0.01-1 \u03bcM) partially activated intrinsic and extrinsic apoptotic pathways, whereas high-dose ATZ (10 \u03bcM) reduced Nrf2-target and spermatogenic gene expression, strongly impairing SSCLC maturation. HD2 cells showed pronounced oxidative stress with robust Nrf2-driven antioxidant responses and BCL2 that supported differentiation at low doses. However, excessive oxidative or proliferative signaling, including CDK1 upregulation at high ATZ concentrations, disrupted redox balance and SSCLC differentiation in HD2 cells. Conclusions: ATZ exerts dose- and genotype-dependent effects on IVS through coordinated regulation of oxidative stress and apoptosis. These findings highlight the interplay between Nrf2-mediated antioxidant defenses, apoptotic signaling, and genetic background in shaping spermatogenic outcomes, providing mechanistic insight into ATZ-induced reproductive toxicity in a human-relevant in vitro spermatogenesis model.",
"41483428": "ID: 41483428\nTitle: TNFRSF13B Variant-Induced TACI Dysregulation Underlies CAEBV Pathogenesis.\nAbstract: The tumor necrosis factor (TNF) receptor superfamily member, transmembrane activator and CAML interactor (TACI) encoded by TNFRSF13B, are extensively involved in immune responses. In our previous work, TNFRSF13B exon 2 variants were recurrently identified in chronic active Epstein-Barr virus disease (CAEBV). Here we aim to reveal the roles of TNFRSF13B variants in CAEBV, and investigate the feasibility of targeting TNFRSF13B/TACI as a new approach to control EBV infection. The lymphoblastoid cell lines (LCL) models carrying homozygous TNFRSF13B exon 2 frameshift mutations were constructed using CRISPR/Cas9. Immunological assays, transcriptomic analysis, and gene silencing experiments were performed on LCL models to measure the effect of TNFRSF13B exon 2 variants and explore the underlying mechanisms. TACI ligands and a TLR9 agonist were applied to modulate TACI signaling and EBV activities. Frameshift mutations in exon 2 of TNFRSF13B significantly up-regulated the short isoforms of TACI (TACI-S) at the expense of its long isoforms (TACI-L) in LCLs. The up-regulated TACI-S induced more intense activation of NF-\u03baB, MAPK, and Rho signaling pathways, leading to the switch of EBV activities to lytic reactivation. The subsequent increased viral load and viral IL-10 provide a rational for the susceptibility of variant carriers to CAEBV. The BAFF trimer, an indirect TACI-signaling inhibitor, also significantly suppressed the EBV lytic program. Gene silencing experiments indicated that XBP-1 might be involved in the TACI-mediated regulation of EBV lytic activities in EBV-immortalized B cells. This study underscores the impact of TNFRSF13B variants on EBV infection and host immune responses, offering insights into CAEBV pathogenesis and potential therapeutic strategies.",

Here, we detail the clinical development and application of an ovarian support cell (OSC) product, Fertilo, to improve the in vitro maturation (IVM) of human oocytes. First, we demonstrate that transcription factor-mediated hiPSC differentiation produces OSCs that improve the oocyte MII maturation rate. To support clinical application, we describe raw material upgrades and the generation of clinically suitable hiPSC seed and master cell banks, with transcriptomic analysis of resultant OSCs showing consistent and reproducible outcomes. Next, we detail analytical release testing and development of a murine oocyte maturation assay to assess product potency. Finally, application of Fertilo in a longitudinal cohort analysis shows improvement in key outcomes, compared with traditional IVM. Our findings demonstrate the first-time clinical development and application of an hiPSC-derived product to promote successful reproductive outcomes.",
"41574959": "ID: 41574959\nTitle: Autosomal Dominant Erythrocytosis Caused by Non-Renal Erythropoietin (EPO) Due to EPO c.-136 G>A Germline Mutation.\nAbstract: We previously reported a five-generation kindred with autosomal dominant erythrocytosis associated with a novel germline promoter variant in the erythropoietin (EPO) gene (EPO c.-136\u2009G>A). This mutation creates a new hypoxia response element (HRE) consensus sequence on the reverse strand suggesting a gain of function mutation. CRISPR/Cas9-edited Hep3B cells harboring the c.-136\u2009G>A variant had increased EPO mRNA and protein expression under both normoxic and hypoxic conditions compared to wild-type cells; functional assays confirmed the activity of the c.-136\u2009G>A variant-induced EPO. Isoelectric focusing analyses of patient urine and plasma showed a more basic EPO isoform pattern, consistent with the reduced sulfated N-glycan contribution, suggesting decreased renal and increased non-renal expression. Luciferase reporter assays confirmed increased transcriptional activation of the mutant promoter. However, chromatin immunoprecipitation did not verify direct hypoxia-inducible factor (HIF)-1/2 binding, suggesting the possible involvement of alternative regulatory elements. These findings support a model in which the EPO c.-136\u2009G>A promoter variant introduces a new HRE that overrides the normal kidney expression resulting in persistent or ectopic non-renal EPO production postnatally. This study expands the spectrum of molecular mechanisms underlying hereditary erythrocytosis and provides novel mechanistic insights into EPO regulation, including its tissue-specific expression.",
"41581067": "ID: 41581067\nTitle: Bioethics in assisted reproduction and embryology.\nAbstract: The use of assisted reproductive therapies, advances in embryo research, and developments in scientific fields such as gene editing and in vitro gametogenesis have attracted the attention of bioethicists for years. On one side, the 14-day rule has faced criticism from embryo researchers advocating for its extension. On the other side, the increasing number of cryopreserved embryos worldwide has raised practical and ethical concerns about their fate. While advancements in scientific research, especially gene editing and in-vitro gametogenesis (IVG), are not yet fully applicable, their potential future use appears to pose significant bioethical questions. In this review, we examine the evolving bioethics of embryo research, focusing on the 14-day rule, the challenges surrounding surplus cryopreserved embryos, and the future dilemmas posed by CRISPR-based gene editing, IVG, and preimplantation genetic testing for polygenic risk (PGT-P). We also highlight the critical role of multidisciplinary, patient-centered counseling in ART practice, to foster informed consent, realistic expectations, and psychosocial well-being. Finally, we underscore the need for anticipatory ethical frameworks and open-society engagement that integrate public deliberation with scientific progress to ensure that reproductive innovation proceeds responsibly, preserving both human dignity and social justice.",
"41593679": "ID: 41593679\nTitle: Adaptation of lentiviral vectors for viral gene therapy and their impact on host cell biology.\nAbstract: Lentiviral vectors (LVVs) are used as a viral gene therapeutic and were derived from human immunodeficiency virus subtype 1 (HIV-1). LVVs are used to deliver and induce the stable expression of transgenes through genome integration. Current clinical LVV delivery systems do not include HIV-1 major accessory genes; however, critical structural and non-structural HIV-1 proteins are encoded by the 4-plasmid combination that composes the 3rd generation LVV transduction systems. LVVs use HIV-1-like mechanisms for viral genome integration and both transgene delivery and expression. LVVs rely on host cell machinery to transcribe and translate transgenes for either knocking down disease-causing genes and/or supplying functional genes in a targeted disease. LVVs integrate into host intronic and intergenic regions due to genomic accessibility, but there are no known biases toward specific target integration motifs. Investigation of LVV integration has uncovered the generation of chimeric LVV-host transcripts and altered host transcript splicing patterns. Several Food and Drug Administration (FDA)-approved LVV-derived therapies are used for treating diseases ranging from beta thalassemia to sickle cell anemia. An increasingly popular application of LVV is in the generation of chimeric antigen receptor (CAR) T cell therapies, which change and enhance T cell antigen specificity and effector function in liquid cancers. In November 2023, all CAR T cell therapies were placed under FDA investigation due to higher-than-expected rates of malignant transformation, hospitalization, and death in treated individuals. LVV integrations driving oncogene expression could be a cause for malignancy development. Current methods for resolving LVV integration patterns are technically limited by the sequencing approach applied allowing for only limited characterization of LVV integration profiles and altered host gene regulation. A comprehensive understanding of LVV integration and its consequences is necessary for understanding how these events influence host cell gene regulation and splicing, possibly identifying tunable variables for enhanced positive clinical outcomes.

"41716912": "ID: 41716912\nTitle: An induced pluripotent stem cell-based chemical genetic approach for studying spinal muscular atrophy.\nAbstract: Spinal muscular atrophy (SMA) is a genetic disease characterized by degeneration of spinal cord motor neurons and neuromuscular junctions. Despite recent developments in therapies for SMA, treatment efficacy largely relies on the administration of drugs early in disease progression and is impacted by underlying patient genetics. Drug discovery for other diseases of the central nervous system (CNS) has also been hindered by heterogeneity in patient genetics and clinical presentations, as well as the need for early intervention. To address these hurdles, we utilized a chemical-genetic-based screening approach to adapt the Connectivity Map (CMAP)/L1000 platform to study SMA. To do this, we differentiated moderate and severe SMA patient-specific induced pluripotent stem cells into neuronal cells utilizing a forward programming differentiation protocol, exposed each to 360 neuroactive or CNS disease-related compounds, and interrogated resulting changes in expression of >400 neural genes in a platform we term CMAPneuro. In doing so, we generated 4,559 transcriptional profiles identifying stimuli that modulate gene expression differences across SMA neurons. Finally, we make these data queryable, allowing the research community to (1) identify CNS disease-related perturbagens that mimic or reverse differentially expressed genes, or (2) explore the transcriptional response of a given perturbation in diverse SMA neuronal cells. Taken together, CMAPneuro represents a novel tool to identify candidate stimuli for follow-up investigation into the biology of SMA and related disorders.",

PKC\u03b1 (protein kinase C alpha), encoded by PRKCA, plays a central role in heart failure pathogenesis. Phosphorylation of PKC\u03b1 at threonine 497 (T497) triggers a series of intramolecular phosphorylation events, leading to its activation. Ablation of T497 phosphorylation leads to reduced stability and activity of PKC\u03b1. We generated mice harboring a phospho-resistant PKC\u03b1 (T497A) mutation in the germline using CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats/clustered regularly interspaced short palindromic repeat-associated 9)-mediated homology-directed repair. To assess the clinical feasibility of postnatal genome editing, we used CRISPR-Cas9 adenine base editing delivered by adeno-associated virus 9 to introduce the T497A substitution into the Prkca gene (PrkcaT497A) in wild-type mice. Mice underwent transverse aortic constriction to model heart failure. Cardiac function, hypertrophy, fibrosis, and transcriptional changes were evaluated by echocardiography, wheat germ agglutinin staining, Masson's trichrome staining, and RNA-sequencing. The editing efficiency of PrkcaT497A was assessed using Sanger sequencing and deep amplicon sequencing. To further explore its clinical potential, we introduced the PRKCAT497A mutation into human induced pluripotent stem cells by nucleofection-mediated adenine base editing. Ca2+ homeostasis was analyzed in Fura-2-loaded human induced pluripotent stem cell-derived cardiomyocytes with PRKCAT497A under chronic AngII (angiotensin II) stimulation. The T497A mutation in PKC\u03b1 prevented its subsequent phosphorylation and led to PKC\u03b1 protein degradation. Four weeks after transverse aortic constriction surgery, wild-type mice showed impaired cardiac function, cardiac remodeling, and increased lung weight. In contrast, PKC\u03b1 phospho-resistant mice showed protection against heart failure-related aberrant changes in cardiac hypertrophy, fibrosis, and cardiac gene expression. Mice administered with adeno-associated virus 9 base editors to prevent T497 phosphorylation exhibited similar cardioprotective effects. In vitro, PKC\u03b1-edited induced pluripotent stem cell-derived cardiomyocytes were protected from AngII-induced impairments in contractility and Ca2+ transients. The editing of PRKCAT497A through adenine base editing represents a potential therapeutic approach for human cardiac diseases.",

At present, the only available curative treatment for sickle cell disease (SCD) is allogenic hematopoietic stem cell transplantation. However, recent advancements in gene therapy offer promising prospects for curing the disease, either through the correction of the pathogenic mutation or the induction of Fetal hemoglobin production. This review focuses on the gene addition and gene editing technologies being currently employed in the treatment of SCD, with a particular emphasis on therapeutic interventions that are undergoing clinical trials globally.

Despite early promise, clinical adoption of IVM has been limited due to lower embryo developmental competence and live birth rates compared to IVF. However, recent advances in the understanding of oocyte physiology, including cumulus-oocyte communication, the regulatory roles of cAMP/cGMP signaling pathways, and endocrine modulation of meiotic resumption, have reignited interest in optimizing IVM protocols. Innovations such as biphasic Capacitation (CAPA) IVM systems and the use of ovarian somatic support cells (OSCs) derived from induced pluripotent stem cells (iPSCs) aim to replicate the dynamic follicular environment more accurately and enhance oocyte competence. Clinical studies suggest that, while IVM still results in modestly lower cumulative live birth rates compared to conventional IVF, it offers significant advantages for selected patient populations, particularly women with polycystic ovary syndrome (PCOS), high ovarian reserve, or those requiring fertility preservation. Importantly, current evidence supports the genetic and epigenetic safety of IVM-derived offspring. As technical refinements continue and professional education expands, IVM is poised to fulfill its potential as a safer, less invasive, and more accessible alternative within the landscape of assisted reproductive technologies.",
"41808594": "ID: 41808594\nTitle: The Impact of Aging on Organ Systems in Sickle Cell Disease: a Comparative Review of Physiological Adaptation and Dysfunction.\nAbstract: Sickle cell anemia (SCA) is a progressive, systemic disorder that can lead to multi-organ dysfunction. While it has traditionally been most prevalent in regions where malaria is endemic, recent epidemiological studies have shown an increasing disease prevalence in non-endemic areas, primarily attributed to global human migration patterns. The severity of SCA typically worsens with age. In early childhood, affected individuals may present with renal hyperfiltration, neurocognitive delays, cardiac remodeling, and skeletal fragility. The presence of these early manifestations often predicts the development of chronic complications later in life, including splenic atrophy, neurodegeneration, and impaired cerebral perfusion. Adequate management of SCA begins with universal newborn screening programs, enabling early detection and the initiation of appropriate interventions. Therapeutic advancements, ranging from disease-modifying agents such as hydroxyurea to curative options including gene therapy and stem cell transplantation, have significantly improved clinical outcomes; however, long-term morbidity remains a significant challenge. This review aimed to explore the effect of aging on pathophysiological changes and the onset of organ-specific complications in SCA patients. It highlights the importance of age-tailored monitoring and a multidisciplinary approach to detect early signs of organ damage, prevent irreversible complications, and consequently improve overall quality of life.",

However, excessive ROS induces oxidative stress, leading to DNA damage, chromosomal aberrations, loss of mitochondrial membrane potential, and ultimately, abnormal differentiation or cell death. This oxidative imbalance is a significant barrier to successful embryonic development and the in vitro culture of stem cells. Innate antioxidant defense systems exist within chicken and mammalian embryos to scavenge excess ROS, a finding that has prompted the strategic addition of antioxidants to culture media. The present review has two primary foci. Firstly, it seeks to expand the understanding of the antioxidant defense mechanisms of the chicken embryo. Secondly, it explores the role of exogenous antioxidant supplementation in the culture of various stem cell types, including embryonic stem cells (ESCs), primordial germ cells (PGCs), spermatogonial stem cells (SSCs), and induced pluripotent stem cells (iPSCs). Enhancing in vitro stem cell survival and directed differentiation through antioxidant supplementation holds significant promise for advancing fields such as tissue regeneration, organ transplantation, and the development of transgenic chicken models for improved production traits, vaccine development, and recombinant protein production.",
"41920273": "ID: 41920273\nTitle: Experimental Models to Study Polyglutamine Spinocerebellar Ataxias: From Mechanisms to Therapeutic Developments.\nAbstract: Spinocerebellar ataxias (SCAs) are a large and heterogeneous group of inherent neurodegenerative diseases. A select group of SCAs are caused by abnormal CAG repeat expansions within the coding region of specific genes (polyQ SCAs). These alterations result in the synthesis of mutant proteins that carry an expanded tract of glutamine residues, which confers on them a toxic gain-of-function that disrupts multiple cellular processes, ultimately resulting in selective neuronal death. PolyQ SCAs are characterized by a core set of clinical features, including progressive cerebellar ataxia, motor incoordination, and neurodegeneration affecting the cerebellum and related neural circuits. At the molecular level, polyQ tracts have been shown to promote protein misfolding and aggregation, which in turn leads to cellular toxicity. Each SCA exhibits a distinctive pattern of cellular vulnerability, clinical progression, and neuropathology; therefore, the development of experimental models has been pivotal in elucidating disease mechanisms and facilitating translational research. In this review, we summarize the main experimental models utilized to study polyQ SCAs. These models include: (1) cellular systems that allow rapid and controlled analysis of molecular toxicity; (2) patient-derived induced pluripotent stem cells, which preserve endogenous gene regulation and genetic backgrounds; (3) non-mammalian organisms such as Drosophila melanogaster, Caenorhabditis elegans, and zebrafish, which support genetic screening and medium-throughput studies; (4) murine models that reproduce in vivo motor deficits, cerebellar degeneration, and transcriptional alterations; and (5) non-human primates (NHPs), which closely resemble human brain structure and function. We discuss the strengths and limitations of each model and underscore their contributions to elucidating the pathophysiology of disease and promoting the development of molecular therapies for polyQ SCAs.",
"41961835": "ID: 41961835\nTitle: Exosomes in oncofertility: emerging roles in chemotherapy-induced reproductive damage and fertility preservation.\nAbstract: Oncofertility has emerged as a critical interdisciplinary field addressing the reproductive challenges faced by cancer patients, particularly those undergoing chemotherapy. While chemotherapeutic agents remain indispensable in cancer therapy, their gonadotoxic effects frequently result in diminished ovarian reserve, impaired spermatogenesis, and long-term infertility. Exosomes - small extracellular vesicles enriched with nucleic acids, proteins, and lipids - are increasingly recognized as key mediators of intercellular communication in both pathological and regenerative contexts. Recent evidence suggests that chemotherapy alters exosome cargo, thereby amplifying cellular stress responses, oxidative damage, and bystander effects in gonadal tissues. Conversely, exosomes derived from mesenchymal stem cells, induced pluripotent stem cells (iPSCs), and other regenerative sources demonstrate the ability to restore ovarian and testicular function by reducing apoptosis, enhancing angiogenesis, and supporting germ cell survival. This dual role positions exosomes as both contributors to reproductive toxicity and promising therapeutic agents in fertility preservation strategies. However, clinical translation remains hindered by challenges including source heterogeneity, isolation methods, safety concerns, and regulatory barriers. This review highlights the emerging roles of exosomes in chemotherapy-induced reproductive damage, explores their regenerative potential, and outlines future directions for their integration into oncofertility practice. Cancer treatments such as chemotherapy save lives, but they often damage the ovaries and testes. This can lead to infertility in both women and men, which is one of the most difficult problems for cancer survivors. Finding ways to protect or restore fertility is, therefore, an important part of cancer care. Our work looks at very small particles called exosomes. These are natural messengers that carry proteins and genetic material between cells. We explain how chemotherapy changes these exosomes in a way that increases damage to reproductive organs. At the same time, we show that exosomes from stem cells may help repair this damage. In laboratory studies, they have been shown to protect eggs and sperm and reduce cell death of the reproductive organs during chemotherapy. Exosomes can also act as simple blood-based tests to detect damage and monitor recovery. This research is important because it points to new, less invasive ways to protect fertility during and after cancer treatment. If successful, exosome-based therapies could give patients not only a chance of survival but also the hope of having children in the future.",

There is a need to generate granulosa-like cells (GLCs) from human induced pluripotent stem cells (hiPSCs) to better model human gonadal development and to test the effects of exogenous or pharmaceutical compounds on the ovary. Here we report a rapid ligand-based protocol for differentiating hiPSCs into cells that express markers of the transient developmental lineages and steroidogenic pathway genes. Single-cell RNA-sequencing (scRNA-seq) analysis identified canonical granulosa cell genes were expressed in a subset of cells and identified new genes of interest that were significantly associated with computationally modeled pseudotime. HSD17B1 was expressed in resulting GLCs but at low levels, suggesting an immature granulosa cell phenotype. The GLCs were produced using a simple culture method that could be augmented for granulosa cell functions such as sustaining oocyte growth. Producing GLCs through protocols such as this one is a first step toward designing large-scale ovarian endocrinology assays and developing personalized cell-based fertility and hormone restoration technologies in the future. This rapid protocol produced cells that express steroidogenic enzyme genes etoc blurb. Kubo and colleagues present a 5-day rapid protocol to generate immature granulosa-like cells from hiPSCs.

This study established an in vitro model of NLRP7 mutation using patient-derived induced pluripotent stem cells (iPSCs) and integrated high-content imaging (HCI) with artificial intelligence (AI) to dissect mutation-induced multi-organellar dysfunction. Multiparametric HCI enabled synchronous capture of cellular and subcellular phenotypes, including mitochondrial function and lysosomal distribution. We developed a bio-inspired AI framework (BioVision-Segmentation) that combines a hybrid Transformer-Voronoi architecture for segmentation with mutual information analysis to quantify organelle interactions. Our findings reveal that NLRP7 mutations disrupt the lysosome-mitochondria crosstalk hub, leading to energy metabolism dysregulation, reactive oxygen species (ROS) accumulation, and organelle spatial distribution defects. Furthermore, transcriptome sequencing corroborated these findings. This study elucidates the organellar pathogenesis of RHMs and provides a technological platform for exploring therapeutic targets, facilitating a shift toward early embryo protection strategies.",

Due to the multitude of diseases of the blood system, such as leukemia and bone marrow failure, it is of utmost importance to understand what regulates the initial formation of this system in the embryo and subsequent cell fate decisions occurring during the development of the different mature blood cell lineages. Research along these lines has been greatly facilitated by the development of embryonic stem cell (ESC) and induced pluripotent stem cell (iPSC)-based methods. Such cells can be genetically altered and produce ample cell numbers, thus being the ideal model to elucidate how our genome controls cell fate decisions. In this review, I summarize work from my laboratory and that of others to highlight how ESC and iPSC-based systems have been used to obtain global information, enhancing our understanding of the genetic basis of hematopoiesis, how specific transcription factors interact with chromatin components to regulate differential gene expression, and how signaling molecules and growth factors modulate this process. I outline how such information can be used to optimize in vitro differentiation into specific cell types for regenerative medicine purposes. Last, but not least, I describe how in vitro systems can inform us about how blood cell development goes astray during disease processes.",

Despite recent advancements in amyloid-beta-targeting immunotherapies, achieving safe and definitive disease control remains a profound clinical challenge. The CRISPR/Cas9 system has emerged as a powerful technology for precision neurogenetics, offering significant potential to address the fundamental questions behind Alzheimer's disease. This comprehensive review delineates the trajectory of CRISPR applications in Alzheimer's disease research and therapeutics. First, we explore the integration of CRISPR in engineering high-fidelity in vitro models, such as isogenic induced pluripotent stem cells and three-dimensional cerebral organoids, alongside advanced in vivo mammalian models. Second, we examine how these platforms facilitate unbiased high-throughput genetic screening to uncover molecular underpinnings regulating tau, lipid metabolism, and neuroinflammation. Third, we critically evaluate precision editing strategies targeting core risk genes (APP, MAPT, APOE, and TREM2), explicitly highlighting the severe physiopathological trade-offs between therapeutic efficacy and loss-of-function toxicity. Finally, we address the ultimate translational bottlenecks impeding clinical application. By dissecting the packaging limits of adeno-associated viral vectors and the physical barricade of the blood-brain barrier, we underscore the necessity of transitioning toward next-generation base editors and non-viral lipid nanoparticles to realize safe and efficacious in vivo clinical gene therapies against Alzheimer's disease.",

Traditional management strategies are primarily palliative and often associated with significant challenges, including iron overload and limited long-term efficacy. Allogeneic hematopoietic stem cell transplantation (HSCT) is a potentially curative option for transfusion-dependent patients, but its broader applicability is constrained by factors that limit its use.

These innovative approaches have demonstrated substantial therapeutic potential, accompanied by favorable safety profiles, in clinical settings. Since the initial investigations, the genome editing tool has rapidly advanced for genetic abnormalities, particularly monogenic blood diseases, including \u03b2-hemoglobinopathies. This method suggests an approach with lower concerns in viral gene integration and insertional mutagenesis issues.

Fine-mapping and melanocyte expression data collectively suggest two potential causal genes with opposite association with risk: higher levels of Rap guanine nucleotide exchange factor 1 (RAPGEF1) and lower levels of uridine-cytidine kinase 1 (UCK1). Colocalization analyses and conditional TWAS suggest multiple causal cis-regulatory sequence variants in partial linkage disequilibrium (LD) to each other. Melanocyte capture-HiC and CRISPR-inhibition demonstrated regulatory interactions between fine-mapped variants and the RAPGEF1 and UCK1 promoters. Focusing on RAPGEF1, we demonstrate RAPGEF1 expression promotes melanocyte growth and drives malignant transformation of human immortalized melanocytes. Following treatment with human EGF, RAPGEF1 overexpression activated both RAP1 and RAS. Further, we show RAPGEF1 expression is significantly enriched in melanomas lacking strongly activating RAS-MAPK mutations, suggesting that RAPGEF1 may promote oncogenic RAS-MAPK signaling in melanomas. Furthermore, in these tumors, we provide preliminary evidence to support the prognostic relevance of RAPGEF1 expression in patients lacking RAS or BRAF mutations.

In combination with induced pluripotent stem cell (hiPSC) reprogramming, in vitro gametogenesis provides an avenue for patient-specific disease modeling approaches. However, further advancements are required, as current protocols are limited to early stages of germ cell development. To get one step closer to this goal, here we aimed to identify optimal conditions for generating high-quality hiPSC lines capable of in vitro germ cell differentiation. We isolated two clinically available somatic cell types, peripheral blood-derived mononuclear cells and cumulus cells from the same female donor, and reprogrammed them into human induced pluripotent stem cells (hiPSCs). We then assessed their differentiation into ectoderm, mesoderm, and endoderm, and evaluated their X-chromosome inactivation status, a critical indicator of stem cell quality. Finally, we compared the capacity of PBMC- and cumulus-derived hiPSCs to differentiate into human primordial germ cell-like cells (hPGCLCs). We found that despite variability between cell lines, hiPSCs from both cell types were capable of generating hPGCLCs and that variations in X-chromosome state did not appear to generally interfere with the process.

Although primed bESCs and bovine expanded potential stem cells have recently been established, their routine maintenance commonly relies on mouse embryonic fibroblast or bovine fetal fibroblast feeder layers, which are complex, labor-intensive, poorly standardized, and incompatible with scalable manufacturing. Here, we report a simplified feeder-free culture platform for bESCs in which a commercially available basal medium is combined with Growth Factor Reduced Matrigel to generate a three-dimensional, niche-mimetic substrate. Using this approach, we successfully derived a novel feeder-free bESCs (FF-bESCs) that can be robustly expanded for more than 60 passages without ROCK inhibitors, while maintaining a normal karyotype, high proliferation rates, and stable expression of core pluripotency markers. Functional assays confirmed that FF-bESCs possess bona fide pluripotency, as evidenced by their ability to form embryoid bodies in vitro and generate teratomas containing derivatives of all three germ layers in vivo. Transcriptomic profiling further revealed that FF-bESCs align with a formative pluripotent state. Notably, these cells can be directed to differentiate into primordial germ cell-like cells.

Placental insufficiency is associated with adverse pregnancy outcomes, including fetal growth restriction, preeclampsia, and pregnancy loss. Moreover, emerging evidence suggests that placental defects are associated with long-term health challenges that manifest well into adulthood; yet the etiologies of such diseases are largely unknown. Defining the mechanistic basis for placental deficiencies, therefore, has important implications for improving both reproductive health and the lifelong well-being of affected children. Down syndrome is characterized by placental defects of unknown mechanistic origin, and notably, individuals with Down syndrome are at increased risk of developing diseases commonly associated with placental insufficiency later in life. Using induced pluripotent stem cells from Down syndrome patients, we found that stem cell-based embryo models (i.e., blastoids) and directed differentiation systems recapitulate trophoblast cell fate defects observed in placentas affected by Down syndrome. Furthermore, we demonstrate that attenuated estrogen signaling contributes to placental syncytialization defects and identify NRIP1, a transcriptional corepressor of estrogen receptor that is located on chromosome 21, as a key driver of trophoblast cell fate defects. Increased gene dosage of NRIP1 in an otherwise diploid cell line phenocopies cell fate defects observed in trophoblasts affected by Down syndrome.

In this study, we analyzed 647 Danish patients with suspected myeloid neoplasms to assess the frequency of germline DDX41 variants and the functional impact of variants of uncertain significance (VUSs) using a cell-based assay, CRISPR-Select. We identified 16 DDX41 variants in 30 patients, 14 of whom were confirmed or predicted as germline variants. Eight germline variants were classified as likely pathogenic/pathogenic (LP/P), and three as VUSs. We generated a monoallelic DDX41 K562 cell line and used it for CRISPR-Select assessment of variant effects on proliferation and survival. Pathogenic variants impaired proliferation, while benign variants did not. Missense variants had a more subtle effect than truncating ones, suggesting hypomorphic phenotypes. One DDX41 VUS had a significant negative effect on proliferation, suggesting it to be pathogenic, while the other two had no effect, suggesting them to be benign.

Although most patients experience resolution of overt clinical symptoms associated with SCD with donor-dominant myeloid chimerism after undergoing HCT or the induction of a substantial amount of alternative hemoglobin after gene therapy, whether the underlying subclinical physiology is normalized in these individuals is unknown. One approach to evaluating the underlying physiology is to characterize the blood rheology of patients after they receive these therapies. We assessed the rheology of 123 blood samples from 69 patients, of whom 43 underwent HCT (32 from matched related donors, 11 from haploidentical donors) and 11 received gene therapy. The results were compared to those for patients treated with hydroxyurea with optimum fetal hemoglobin response (HUOptimum) (n\u2009=\u200915).

Aside from this approved therapy for sickle cell anemia, several CRISPR/Cas-based therapies are currently under development or testing for a range of chronic diseases, including viral diseases like human immunodeficiency virus type 1 (HIV-1) infection, genetic diseases like familial hypercholesterolemia, and cancer. The success of these therapies hinges on the effective delivery of CRISPR/Cas9 components to target regions, efficient Cas endonuclease editing, repair profiles generated, and their resulting outcomes. Here, we discuss the factors that influence the generation of CRISPR/Cas9-generated repair edits, the overall profiles, and outcome prediction(s), as well as the analytical tools that have been developed to date. Finally, how this technology has been used towards a functional HIV-1 cure is discussed.",

One of the first embryonic lineages to be specified in the human embryo is the germ cell lineage, marked by the induction of the primordial germ cells (PGCs). The PGCs are the sole founder population of the gametes later in life, and their specification is a critical first step towards the organism's fertility. Here, a robust protocol for generating PGC-like cells (PGCLCs) from human induced pluripotent stem cells (hiPSCs) is described, starting with the initial evaluation of the pluripotent state and cellular characteristics of the hiPSCs to ensure effective PGCLC differentiation. For this, the effects of different cell densities, plate coatings, and hiPSCs used for PGCLC differentiation are discussed. Finally, a workflow for characterization and quantification of hPGCLCs, using immunofluorescence and flow cytometry, is provided. The differentiation protocol focuses on conditions that are easy to establish and test in most laboratories and can be adjusted as necessary. Moreover, this protocol is fast, allowing determination of whether hiPSCs are suitable for PGCLC differentiation. The protocol aims to promote consistency and compatibility in hPGCLC outcomes across different hiPSC lines and culture platforms, ensuring robust yields that support reliable characterization and further optimization of downstream differentiation steps toward successful in vitro gametogenesis in humans.",

From the groundbreaking research, the ultimate battle of the prizes and patents to a number of books, the science of CRISPR continues to be significant in the biomedical field. For many decades now, the emergence of synthetic biology as an intervention to correct diseases has become the foundation of biomedical research. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based genetic editing has become a common place for routine investigation of scientific hypotheses in pre-clinical settings. More recently, CRISPR-based diagnostic testing kits for SARS-CoV-2 have showcased a translational output. Furthermore, a technological landmark was achieved when the Food and Drug Administration (FDA) approved the first CRISPR-based gene therapy (exa-cel) to edit erythroid specific enhancer region of BCL11A in hematopoietic stem cells, introduced in patients suffering from sickle cell anemia to achieve durable remission. In this review, we provide a snapshot into the most important milestones along the journey of CRISPR from its discovery in bacteria to its usage in precision medicine. The intervention of machine learning tools has now intertwined complex biology with high-throughput scalable outputs. Given the vast amount of information on CRISPR, we try to pin down key take-home messages for scientists as well as non-scientist readers. This review article attempts to understand why and how CRISPR remains significant and seamlessly integrates in the emerging era of new technologies.",

An inducible and germline-restricted ablation strategy is therefore needed to create sterile recipients without compromising somatic development. Using CRISPR/Cas9-mediated homology-directed repair, we inserted three inducible suicide-gene cassettes (iCaspase9, RapaCasp9, and CD) into the endogenous DAZL locus of chicken PGCs. All knock-in lines showed stable reporter expression and retained typical PGC morphology. Comparative functional analyses identified iCaspase9 activated by AP20187 as the most sensitive and specific ablation system, achieving near-complete killing at nanomolar concentrations without detectable toxicity in control cells. RapaCasp9 induced with rapamycin also ablated engineered PGCs efficiently, but rapamycin caused marked non-specific growth inhibition in control cells. Replacing rapamycin with the synthetic A/C heterodimerizer AP21967 largely eliminated this off-target toxicity while preserving rapid and robust killing. By contrast, yeast-derived CD variants did not substantially improve 5-fluorocytosine sensitivity in chicken PGCs. DAZL-restricted iCaspase9/AP20187 and the optimized RapaCasp9/AP21967 system provide efficient inducible kill switches for chicken PGCs in vitro. These platforms establish a practical genetic toolkit for generating sterile surrogate hosts to support avian genome editing, germline replacement, and Sire Dam Surrogate breeding.",

While rodent models have defined the canonical core circuitry of pluripotency, the extent to which these regulatory hierarchies are conserved in large mammals is unclear. Here, we provide evidence that SOX15 contributes to the species-specific regulatory network as a modulator that sustains pluripotency and preserves functional differentiation capacity in porcine embryo-derived stem cells. Comparative sequence analysis revealed strong conservation of the SOX15 HMG domain across mammals, yet promoter divergence suggested lineage-specific regulatory evolution. Transcriptomic profiling demonstrated that, unlike in mice, SOX15 is robustly upregulated from the 2-cell stage and remains highly expressed in the porcine epiblast, coinciding with key windows of pluripotency establishment. In porcine embryo-derived stem cells, stable SOX15 knockdown resulted in reduced colony integrity, diminished alkaline phosphatase activity, impaired proliferation, and downregulation of core pluripotency genes, including OCT4 and NANOG. Furthermore, loss of SOX15 disrupts embryoid body formation and abolishes teratoma-forming capacity in vivo. This deficit likely reflects impaired pluripotency, but may also be attributed to compromised cell survival or proliferative fitness following transplantation. Notably, comparable perturbations in mouse models do not produce equivalent phenotypes, underscoring a lineage-dependent functional divergence. Together, our findings suggest that SOX15 contributes to the support of the porcine pluripotency network, and hint at evolutionary plasticity in the hierarchical architecture of mammalian pluripotency. These findings move beyond the rodent-centric paradigm and offer a refined perspective on the evolutionary plasticity of pluripotency networks, highlighting SOX15 as a pivotal lineage-specialized node governing naive pluripotency in large mammals. Notably, these inferences are based on functional perturbation using a single validated miRNAi construct; definitive confirmation of SOX15-specific causality will require future orthogonal validation via independent knockdown sequences, CRISPR interference, or RNAi-resistant rescue experiments.",

Although ssODN sequence fidelity is critical to the safety and efficacy of editing, standard quality control methods cannot resolve individual nucleotide errors. Methods: We performed deep sequencing of ssODNs from three manufacturers and amplicons from edited hematopoietic stem/progenitor cells. Results: We find that synthesis errors are present in all ssODNs tested at rates that vary more than two-fold among manufacturers, at positions that are dependent on sequence context. These synthesis errors are propagated into the genome by HDR at frequencies proportional to their abundance in the ssODN. In our sickle cell mutation correction protocol, the most prevalent SNEs are predicted to produce benign \u03b2-globin variants, while the less frequent frameshift deletions are predicted to generate \u03b2-thalassemia-like alleles. Conclusions: Current quality control standards are insufficient to detect these errors, and deep sequencing of ssODNs should be incorporated into regulatory submissions for clinical gene editing programs.",

Although stem cell-based therapies have shown promise for vascular regeneration, their clinical translation has been limited by poor survival, insufficient engraftment, functional heterogeneity, and immune rejection. Recent advances in genome-editing technologies, including CRISPR/Cas9, base editing, and prime editing, have provided powerful tools for overcoming these limitations through precise genetic modification of stem cells. Gene editing can enhance angiogenic potential, improve resistance to ischemic stress, augment paracrine activity, promote endothelial maturation, and reduce immunogenicity. In this review, we outline the current genome-editing toolbox and its application to stem cell engineering for vascular regeneration in ischemic disease. We also examine emerging therapeutic concepts, universal donor cell platforms, and key issues in safety and ethics, with a focus on translational pathways. Taken together, advances at the interface of genome editing and stem cell biology are likely to accelerate the development of regenerative therapies that deliver more durable vascular repair in ischemic vascular disease.",
"42511636": "ID: 42511636\nTitle: Efficient Gene Editing in Fish Primary Germline Stem Cells.\nAbstract: Genome editing by the CRISPR/Cas9 system is widely used for production of gene-modified animals, including fish. However, efficient gene editing in fish cultured cells, in particular germline stem cells (GSCs), is challenging, likely due to the difficulty in transfecting these cells. The ricefield eel (Monopterus albus), a sequential hermaphroditic species, is a freshwater fish of significant economic value in China. In this work, we report a simple method that can achieve high gene editing efficiency in primary GSCs of fish species, including ricefield eel. High transfection efficiency (50-95%) is achieved in fish GSCs by using a microchannel-based cell transfection system. Gene editing efficiency of up to 60% in primary ricefield eel GSCs is achieved using an integrated CRISPR/Cas9 vector strategy. High gene editing efficiency is also achieved in gibel carp (Carassius gibelio) GSCs and the medaka spermatogonial stem cell line SG3, demonstrating the general applicability of our method. Our data suggest that efficient transfection is key to high gene editing efficiency in fish cultured GSCs. This study establishes an efficient and reliable gene editing system for fish GSCs, which may facilitate the creation of new germplasm of genetically difficult-to-breed fish by combining GSC transplantation with gene editing techniques.",

Conventional treatments, such as blood transfusions, iron chelation, fetal haemoglobin induction, and allogeneic haematopoietic stem cell transplantation, have improved outcomes but remain limited by treatment-related toxicity, donor availability, and incomplete curative potential. Methods: A narrative literature review was conducted using PubMed up to 2025. Search terms included \"sickle cell disease,\" \"sickle cell anemia,\" \"\u03b2-thalassemia,\" \"transfusion-dependent beta-thalassemia,\" \"gene therapy,\" \"gene addition,\" \"gene editing,\" \"CRISPR-Cas9,\" \"lentiviral vector,\" \"children,\" \"paediatric,\" and \"pediatric.\" Relevant clinical trials, reviews, consensus statements, and guidelines were selected and qualitatively analysed. Results: Gene therapy for \u03b2-haemoglobinopathies is based mainly on two strategies: gene addition and gene editing. Gene addition uses lentiviral vectors to introduce functional or modified \u03b2-globin genes into autologous haematopoietic stem cells, whereas gene editing targets regulatory pathways, particularly BCL11A, to reactivate fetal haemoglobin synthesis or correct disease-causing mutations. Clinical studies have shown encouraging outcomes, including transfusion independence in many patients with \u03b2-thalassaemia and marked reduction or elimination of vaso-occlusive crises in sickle cell disease. Paediatric and adolescent data are increasingly promising, although still limited. Conclusions: Gene therapy is reshaping the treatment landscape of \u03b2-haemoglobinopathies by offering a personalised and potentially curative approach. However, long-term safety, conditioning toxicity, fertility preservation, accessibility, costs, and implementation in high-prevalence regions remain critical challenges. Further studies are needed to optimise patient selection and expand equitable access.",
"42512296": "ID: 42512296\nTitle: Development of a Cre-Inducible Rabl6a Transgenic Mouse Model That Enhances Sarcoma Growth In Vivo.\nAbstract: Background: Malignant peripheral nerve sheath tumors (MPNSTs) are deadly sarcomas that arise from Schwann cells and lack effective therapies. RABL6A is an oncogenic Rab-like GTPase whose expression is associated with worse survival in many human cancers. It is required for human MPNST cell survival, and its expression is dramatically increased in patient MPNSTs compared to benign precursor lesions. Methods: To model elevated expression of RABL6A in vivo, we developed transgenic mice expressing Cre-inducible Rabl6a. These Rabl6a-tg mice express the murine Rabl6a cDNA with a 5' hemagglutinin [HA] epitope sequence downstream of a CMV enhancer and separated by a lox-stop-lox cassette. Double transgenic DhhCre; Rabl6a-tg mice were generated to achieve Schwann-cell specific Cre expression from the Desert hedgehog (Dhh) promoter. De novo MPNSTs were induced by CRISPR editing of Nf1, Ink4a, and Arf genes in the mouse sciatic nerve. Results: Cre-dependent expression of transgenic Rabl6a was verified at the mRNA and protein levels in Cre-positive mouse embryo fibroblasts and tissues. Increased Rabl6a expression in DhhCre; Rabl6a-tg mice had no effect on de novo MPNST initiation but significantly accelerated tumor progression relative to DhhCre control mice. The Rabl6a phenotype was associated with increased tumor angiogenesis but not proliferation. Interestingly, many MPNSTs in the DhhCre background exhibited varying levels of rhabdomyoblastic (RMB) features. That immature muscle cell phenotype is a hallmark of malignant Triton tumors, a rare histological variant of human MPNSTs associated with worse outcomes. Conclusions: These data provide direct evidence that Rabl6a is a functional driver of MPNSTs while establishing Rabl6a-tg mice as a suitable model for investigating Rabl6a's role in other lethal RABL6A-high tumors.",
"42513228": "ID: 42513228\nTitle: Breast Cancer: Epidemiology, Molecular Classification, Diagnostics and Evolving Treatment Paradigms.\nAbstract: Breast cancer remains one of the most prevalent malignancies affecting women worldwide and continues to be a leading cause of cancer-related morbidity and mortality. Patients may present with either localized or advanced disease, with clinical outcomes increasingly influenced by molecular subtype and genetic profile. This review highlights the key genetic factors involved in breast cancer, current diagnostic and therapeutic strategies, and promising emerging approaches that may shape future clinical management. Breast cancer diagnosis typically involves clinical breast examination, imaging techniques such as mammography and ultrasound, and confirmatory biopsies. Genetic mutations in specific genes are strongly linked to the development, progression, and metastasis of the disease. Treatment options for localized breast cancer continue to include surgery (lumpectomy or mastectomy) and radiotherapy, combined with systemic therapies tailored to tumor biology, such as endocrine therapy, human epidermal growth factor receptor 2 (HER2)-targeted therapy, and cyclin-dependent kinase (CDK)4/6 inhibitors. For advanced or metastatic breast cancer, recent therapeutic advances include the use of immunotherapy (e.g., immune checkpoint inhibitors), Poly (ADP-ribose) polymerase (PARP) inhibitors for Breast Cancer gene (BRCA)-mutated cancers, antibody-drug conjugates, and novel targeted agents, which have significantly improved patient outcomes in selected populations. Recent findings in breast cancer genetics have highlighted the critical role of germline and somatic mutations, particularly in genes such as BRCA1, BRCA2, phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), and TP53, in driving tumor initiation, progression, and therapeutic response. Molecular profiling and next-generation sequencing technologies have enabled more precise tumor classification and facilitated the development of personalized treatment strategies. Despite these advances, treatment resistance and disease recurrence remain major challenges, particularly in aggressive subtypes such as triple-negative breast cancer. Consequently, ongoing research is exploring alternative and complementary approaches, including nanotechnology-based drug delivery systems, gene editing techniques such as clustered regularly interspaced short palindromic repeats-Cas9 (CRISPR-associated protein 9) (CRISPR-Cas9), cancer vaccines, and the integration of traditional and plant-derived compounds. These strategies aim to enhance therapeutic efficacy, reduce systemic toxicity, and overcome resistance mechanisms.",

Previously, we demonstrated that granulosa cells (GCs) from young mice could be effectively reprogrammed into chemically induced pluripotent stem cells (GC-CiPSCs), which can generate functional oocytes. Here, we investigated whether GCs isolated from reproductively-aged mice could similarly generate germ cells. Old GC-CiPSCs reprogrammed from GCs isolated from reproductively-aged mice exhibited pluripotent gene expression profiles comparable to those of embryonic stem cells and young GC-CiPSCs. However, old GC-CiPSCs displayed compromised mitochondrial function and a reduced capacity to differentiate into primordial germ cell-like cells (PGCLCs). Mitochondrial enhancement did not improve PGCLC induction efficiency in old GC-CiPSCs. However, inhibiting the ERK/MAPK signaling pathway improved the induction efficiency of PGCLCs from old GC-CiPSCs. These findings demonstrate functional deficits in generating PGCLCs from aged mouse GC-derived iPSCs and identify a strategy to improve PGCLC induction efficiency from senescent GCs.",

Recently, the Ministry of Health in Saudi Arabia approved CRISPR-Cas9 for treating Sickle Cell Disease and beta thalassemia. This study aims to assess the Taif population's opinion on gene editing and their knowledge of genetic modification. In this cross-sectional study, a questionnaire was distributed online from March 2, 2024, to June 15, 2024, to 747 residents of Taif City aged 18 and older. Among the respondents, 14.7% reported that they or their family members suffer from a hereditary disease, and 65.7% either work or study in the healthcare field or have a family member involved in healthcare. Additionally, 50.7% had previously heard of genetic modification. Marital status, number of children, and education level did not significantly influence opinions on genetic editing, whereas affiliation with the healthcare field was significantly associated with greater acceptance\u00a0(p\u2009=\u20090.023), while a family history of hereditary disease showed a trend toward significance (p\u2009=\u20090.055). Public opinion strongly supports using genetic editing to treat life-threatening diseases in adults and embryos (63.2% and 73.6%, respectively). However, opinions are more divided on non-disease traits. Many respondents expressed interest in enhancing intelligence (73.8%) and strength (75.8%), as well as altering height (67.8%) and hair color (60.7%). While support was strong for therapeutic use, opinions were divided on enhancement, reflecting ethical tension despite high interest in modifying non-disease traits. Notably, 50.7% believed that using genetic editing for non-medical purposes crosses ethical boundaries and exceeds nature's limits. Awareness of gene-editing techniques was not significantly associated with acceptance (p\u2009=\u20090.108). In conclusion, public acceptance of gene editing in Taif is high, particularly among healthcare-affiliated individuals. Increasing public awareness remains essential to bridge ethical concerns and support informed engagement.",

We generated an endogenous FOXL2-P2A-tdTomato reporter human induced pluripotent stem cell (hiPSC) line using CRISPR/Cas9 knock-in and reporter-guided transcription factor (TF) programming to produce fetal granulosa-like cells (FGLCs). A flow cytometric TF screen identified TCF21, WT1-KTS, and NR1H4 as the strongest FOXL2 inducers, and combinatorial optimization showed that removing TOX3/ETV5 and adding NR2F2 substantially increased the FOXL2-positive fraction. Bulk RNA-seq, principal component analysis, and TF activity inference positioned the induced cells close to early-gestational human fetal granulosa cell profiles. In a mouse IVM, in vitro fertilization (IVF), blastocyst culture, and embryo transfer pipeline, FGLC supplementation did not change nuclear maturation rates but improved downstream development, most clearly increasing offspring production from cumulus-oocyte complexes. A comprehensive safety assessment of F0 offspring derived from FGLC-treated oocytes revealed a normal sex ratio, postnatal growth, gross anatomy, gonadal histology, and modified SHIRPA neurobehavioral profiles. Next-generation natural mating and germ cell assays demonstrated preserved fertility, normal IVF outcomes, and normal sperm parameters in the F1 generation. These results establish a scalable strategy for generating fetal granulosa-like supporting cells from hiPSCs and provide an effective and multi-generational safety framework for oocyte-contact IVM interventions.",
"42533346": "ID: 42533346\nTitle: Cardiac function in zebrafish embryos is linked to an androgen receptor-adrenomedullin-proepicardium axis.\nAbstract: Congenital heart defects (CHDs) comprise the most common congenital malformation affecting nearly 1% of all newborns. In individuals with sex chromosome aneuploidy syndromes, however, the prevalence reaches up to 50% of all livebirths. One commonality to these syndromes is a marked reduction in sex hormones, particularly androgens. Androgen receptor (Ar) insufficiency represents a culprit in the pathophysiology of adult onset cardiovascular disease and arrhythmia, but there are no reports regarding Ar function during heart development. This is surprising as androgens along with its nuclear receptor exist already during early development, even before gonads develop and become functional. We evaluated the role of the Ar during vertebrate heart development by generating loss-of function in zebrafish embryos via pharmacological inhibition, transient CRISPR/Cas9 treatment, or interference of splicing as well as murine cell culture. Attenuation of Ar function in zebrafish embryos prevents normal cardiac morphology and physiology as apparent by edema, bradycardia and arrhythmia. Molecularly, we identified increased abundance of adrenomedullin (Adm) 2a as a likely cause for the observed defects. Cellularly, these phenomena may be linked to impaired formation of proepicardial cells, which are reported to intermingle with cells of the conduction system and influence cardiac pacing. A disrupted Ar - Adm2 axis possibly contributes to the increased frequency of CHD in individuals suffering from sex chromosome aneuploidy syndrome. Testosterone function is generally mediated by androgen receptors in the nucleus of the cell. Interestingly, the androgen receptor exists already in early embryos, long before sexual maturation will be initiated. This study aimed to investigate the function of the androgen receptor during heart development using zebrafish embryos. Embryos lacking functional androgen receptors display severely impaired heart development resulting in a slower and irregularly beating heart. Consistently, several important structures of the heart including the conduction system necessary for cardiac rhythmicity fail to form and function properly in the absence of androgen receptor function. Loss of androgen receptor function leads to elevated expression of adrenomedullin 2a, which has previously been implicated in heart development and function. Consistent with a study reporting adrenomedullin 2a originating from the proepicardium loss of proepicardial genes could be observed in the absence of the androgen receptor. Taken together, this study identifies a novel role of the androgen receptor during early heart development, most likely independent of the later biological sex.",

Pathogenic LMNA genetic variation may lead to autosomal dominant cardiomyopathy, though the severity and rate of progression can vary with the specific nucleotide change and location. Prior studies showed that induced pluripotent stem cells (iPSC)-derived cardiomyocytes (iCMs) with LMNA R541C exhibited reduced LMNA protein abundance, increased sarcomere disorganization, and abnormal electrophysiology. We investigated the LMNA-R541C variant that exhibits a highly penetrant and severe clinical cardiomyopathy phenotype using transcriptomic analysis of iCMs. Patient-derived iPSCs with CRISPR-corrected (clustered regularly interspersed short palindromic repeats) isogenic control cells and CRISPR knock-in LMNA-R541C heterozygous iPSCs were generated for isogenic controlled experiments. In differential gene expression analyses we observed that LMNA R541C/WT iPSC-derived cardiomyocytes had consistent perturbations in 123 genes across CRISPR-corrected and knock-in experiments compared to controls. Pathway analysis identified that the G2M checkpoint and oxidative phosphorylation processes were consistently dysregulated and confirm these findings in previously published iPSC and murine models. These results implicate perturbed gene expression and pathways that may contribute to the severe phenotypes in LMNA-R541C. Informatic analysis of pathways suggests several drug classes including multiple cardiac glycosides as potential targeted therapeutic candidates to be explored.",

We first characterized the physical barrier posed by the chorion using TEM (Transmission Electron Microscope) and established that its removal is prerequisite for effective delivery. A systematic optimization of electroporation parameters for dechorionated embryos identified optimal conditions (e.g., poring pulse: 25\u00a0V, 20 ms; transfer pulse: 5\u00a0V, 50 ms) that ensured high embryo survival and robust eGFP mRNA transfection. Applying this protocol, we achieved targeted gene knockout by electroporation-mediated delivery of Cas9 ribonucleoproteins (RNPs) against multiple loci. Targeting the tyr locus resulted in a phenotypic albinism rate of (38.6\u2009\u00b1\u20093.30)%. Furthermore, we incorporated polyglutamic acid (PGA) to modify the RNP complexes (target tyr), which inhibited aggregation and enhanced editing efficiency to (44.45\u2009\u00b1\u20091.41)%, outperforming a commercial. electroporation system, while targeting the pigmentation-related gene slc24a5 yielded an albinism or hypopigmentation rate of (38.33\u2009\u00b1\u20092.62)%.

Gene editing and hematopoietic stem cell transplantation have changed the therapeutic landscape, but their cost, technical complexity, and procedure-related risks still limit their wider use. For this reason, pharmacological induction of fetal hemoglobin (HbF) remains an important therapeutic strategy. HbF reduces HbS polymerization and is associated with lower disease severity, morbidity, and mortality. Among the mechanisms involved in \u03b3-globin silencing, epigenetic regulation offers several targets that can be explored using small molecules. This review discusses medicinal chemistry approaches primarily targeting HDAC1/2, LSD1, and DNMT1, with emphasis on inhibitor classes, binding mechanisms, structural features, preclinical evidence, and translational limitations. The available data show that each target presents a distinct set of challenges. HDAC-directed strategies require improved isoform and cellular selectivity; LSD1 inhibitors must reconcile strong HbF induction with the risks associated with prolonged target engagement; and DNMT1 modulation is moving from DNA-incorporating nucleoside analogs toward reversible non-nucleoside inhibitors. We also discuss emerging approaches, including multi-target epigenetic modulation and targeted protein degradation.

These proteins, highlighted by tandem WD (Trp-Asp) motifs forming a stable \u03b2-propeller structure, serve as versatile platforms for protein-protein and protein-DNA interactions, facilitating the assembly of multiprotein complexes and the integration of environmental and hormonal signals into specific physiological responses. In plants, WD40 proteins orchestrate essential functions such as anthocyanin biosynthesis, blooming timing, embryogenesis, gametogenesis, and fruit development, often through regulatory modules like the MYB-bHLH-WD40 (MBW) complex. In addition to development, they serve as crucial centers for adaptation to abiotic and biotic stress by regulating phytohormonal interactions, maintaining reactive oxygen species balance, and facilitating ubiquitin-mediated protein degradation, especially via SCF E3 ligase complexes. These roles relate significant hormone pathways, such as abscisic acid, auxin, gibberellin, ethylene, and brassinosteroids, to environmental interactions. Recent progress in CRISPR-based functional genomics, interactome mapping, and high-resolution structural modeling is revealing the plasticity and evolutionary conservation of WD40 scaffolds.

Beyond technological development, several measurable parameters are emerging as potential biomarkers, including fetal hemoglobin (HbF), F-cell proportion, HbF/F-cell, editing durability, and long-term clonal monitoring. Clinical studies demonstrated that disruption of the BCL11A enhancer or editing of the HBG1/2 promoter can induce sustained HbF reactivation, which is associated with reduced transfusion burden or transfusion independence in transfusion-dependent \u03b2-thalassemia and improved clinical outcomes in sickle cell disease. Near-pancellular HbF distribution and HbF/F-cell levels above anti-sickling thresholds further support the pharmacodynamic value of HbF-related biomarkers. Long-term follow-up studies have also incorporated editing durability and clonal monitoring into safety assessment frameworks. Emerging platforms such as RNA Gene Writer and CD90-targeted virus-like particles have demonstrated the feasibility of in vivo hematopoietic stem cell editing, although challenges related to targeting efficiency, delivery specificity, immunogenicity, and long-term safety remain. Overall, ASH 2025 suggests a shift from achieving gene editing to quantifying efficacy, durability, and safety, with standardized biomarker frameworks likely to play an increasingly important role in future clinical translation.",

This study employs somitoids, three-dimensional models of human somitogenesis, to investigate how transcriptional programs and culture conditions influence somite formation and segmentation. We show that pre-differentiation culture medium impacts the developmental potential of induced pluripotent stem cells (iPSCs), with StemFit medium and Matrigel embedding outperforming mTeSR Plus medium in generating robust somite-like structures. Strikingly, these differences arise despite only subtle changes in transcriptomic and time-resolved proteomic profiles. P300-based proximity labeling also reveals a largely overlapping set of chromatin-associated regulators across iPSC conditions. In somitoids, enhancer-associated profiling highlights factors linked to somitogenesis, including MESP2 and TBX6. Knockout of three identified regulators, BPTF, RBPJ, and CITED2, demonstrate their essential roles in somite formation. Together, these findings highlight how culture conditions and enhancer-associated networks influence early human development and demonstrate somitoids as a scalable system for functional genomics.",

We and others recently identified pathogenic variants in SLF2 and SMC5 as the cause of Atelis Syndrome, a neurodevelopmental disorder accompanied by hematological abnormalities, including anemia and lymphopenia. However, the mechanisms underlying the associated hematopoietic dysfunction remain unclear. Through longitudinal follow-up and re-evaluation, we found that some patients developed MDS at a young age. To elucidate the bases of these hematopoietic defects, we analyzed hematopoietic progenitor cells (HPCs) derived from patient-specific induced pluripotent stem cells harboring compound heterozygous SLF2 mutations. Mutant HPCs exhibited impaired colony-forming capacity, defective erythroid differentiation with a myeloid bias, and markedly reduced engraftment in xenotransplantation assays. SMC5 knockdown in cord blood CD34+ cells impaired colony formation. Mechanistically, disruption of the SLF2-SMC5 axis induced genomic instability, p53/p21 activation, and a senescence-like phenotype. ATAC sequencing revealed epigenetic features characteristic of hematopoietic stem cell (HSC) aging, including increased chromatin accessibility at PU.1 motifs associated with myeloid bias. These findings demonstrate that SLF2 and SMC5 dysfunction drives premature HSC aging, bone marrow failure, and predisposition to MDS, revealing Atelis Syndrome as a previously unrecognized IBMFS.",

However, the path to this milestone reveals a pattern of MSCs failing in late-phase clinical trials. Multiple sources of heterogeneity may explain these results, including variability in donor and recipient biology, product manufacturing and characterization, and trial design. For example, certain subsets of acute GVHD patients, particularly those with inflammatory/immune activation, may derive the greatest clinical benefit from MSCs. Trials failing to stratify for this patient-level heterogeneity risk failure while obscuring signals of efficacy in responsive subgroups. Improving trial design considering heterogeneity requires leveraging advances in MSC manufacturing and refining clinical trial methodologies. The development of pooled and early-passage MSCs, induced pluripotent stem cell-derived (iPSC)-MSCs, biomaterial-encapsulated MSCs, and gene-edited or chimeric antigen receptor-expressing MSCs may reduce heterogeneity and improve trafficking to and survival at disease sites. Equally important, trial methodologies must explicitly address heterogeneity from MSC manufacturing and patient enrollment. Adaptive/Bayesian designs and master protocols may allow multiple biomarkers and MSC products to be tested simultaneously, with successful combinations being translated into practice, drawing from strategies that have been successful in precision medicine.",

CRISPR/Cas9 technologies have advanced avian genome editing by enabling targeted editing of genes and traits for production, health, reproduction, and welfare. This review critically evaluates genome-editing tools in avian PGCs, including CRISPR/Cas9, transcription activator-like effector nucleases (TALENs), base editing, and prime editing. Germline transmission efficiency, suitability, precision, and heritability are compared. Efficiency, cytotoxicity, and translational feasibility of delivery strategies, including viral vectors, electroporation and the use of ribonucleoproteins are assessed. Applications of these techniques in chickens are for muscle growth via myostatin (MSTN) gene disruption, viral resistance via editing of the sodium/hydrogen exchanger 1 (NHE1) gene, and control of male and female ratios through modification of sex determination genes. Additionally, applications in biopharmaceutical protein production and animal biodiversity conservation are also explored. Despite advances, some limitations remain, including low efficiency of homology-directed repair, off-target effects, mosaicism, and variability in transmission through the germ line. Current evidence demonstrates a significant lack of germline validation and scalability creating barriers to translate this potential into commercial avian production, especially, poultry breeding. Regulatory frameworks and their implications for food and commercialization are also discussed. Future research should prioritize precision editing, scalable delivery systems, and regulatory alignment to enable practical, ethical, and responsible implementation.",

This review summarizes the clinical development of novel treatments for both non-transfusion-dependent and transfusion-dependent \u03b2-thalassemia, including approved therapies, agents in active development, and programs that have been discontinued. Disease-modifying strategies have focused on improving ineffective erythropoiesis, correcting iron dysregulation, and restoring red blood cell metabolism. Luspatercept and mitapivat have demonstrated clinically meaningful improvements in hemoglobin levels and reduction of transfusion burden and are now approved in multiple jurisdictions. Additional pyruvate kinase activators, such as etavopivat, are undergoing clinical evaluation. Curative approaches have advanced substantially through gene addition, gene editing, and base editing technologies. Approved therapies, including betibeglogene autotemcel and exagamglogene autotemcel, have achieved high rates of durable transfusion independence, while emerging platforms aim to further improve efficacy, safety, and accessibility. At the same time, several promising approaches targeting fetal hemoglobin induction, iron metabolism, and ineffective erythropoiesis have failed to demonstrate sufficient clinical benefit despite preclinical proof of concept, highlighting the complexity of therapeutic development in \u03b2-thalassemia. Future priorities include refining patient selection, generating real-world and comparative effectiveness data, developing clinically meaningful response criteria, expanding pediatric access, and addressing the substantial cost and accessibility challenges associated with novel therapies.",

Here we present OptiPrime, a machine learning model of PE efficiency based on current understanding of PE mechanisms. OptiPrime achieves state-of-the-art accuracy on PE efficiency prediction and enables prediction of nicking guide RNA (PE3) and dual pegRNA (twinPE) outcomes. We validate that OptiPrime has learned the determinants of mammalian mismatch repair (MMR) and is well suited for nominating MMR-evasive silent edits that improve PE efficiency. We demonstrate the use of OptiPrime in a variety of prospective therapeutic contexts in primary human and mouse cells.

No approved therapy restores myocardium lost to infarction. The adult heart replaces cardiomyocytes at approximately 1% per year in young adults, declining to about 0.45% per year with ageing, far below what is needed to recover the more than one billion cells destroyed by a large myocardial infarction. Cell-based regenerative strategies have been investigated for more than two decades, encompassing bone marrow mononuclear cells (BM-MNCs), mesenchymal stromal cells (MSCs), cardiac progenitor cells, cardiosphere-derived cells (CDCs), skeletal myoblasts, and induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs). Safety has been consistent. Efficacy has been modest and variable: the CADUCEUS trial demonstrated scar mass reduction with CDCs without proportionate ejection fraction improvement; the Phase 1/2 POSEIDON trial confirmed MSC safety in 30 patients; and the Phase 3 DREAM-HF trial, enrolling 537 patients, failed its primary endpoint (HR 1.2, p = 0.406). Mechanistic work has established that transplanted cells engraft poorly and exert their benefit principally through paracrine signalling mediated by secreted extracellular vesicles and exosomes carrying microRNAs, trophic factors, and immunomodulatory proteins. For iPSC-CMs, electrophysiological immaturity and arrhythmogenic risk in primate models remain unresolved barriers. Emerging strategies include CRISPR-engineered hypoimmune iPSC lines, bioengineered cardiac patches, injectable hydrogel scaffolds, and engineered exosome platforms. This review provides a comprehensive synthesis of preclinical and clinical evidence, examines translational barriers, and identifies the scientific and regulatory priorities required before these therapies can enter routine clinical practice.",

These conditions are characterized by impaired cholesterol synthesis together with the accumulation of disease-specific sterol intermediates. Current experimental and clinical evidence suggests that pathogenesis reflects both cholesterol insufficiency and sterol-mediated toxicity, including oxidative stress, perturbed developmental signaling, membrane dysfunction, and impaired neurodevelopment. Experimental models have played a central role in elucidating these mechanisms and in evaluating emerging therapeutic strategies. This review provides a comprehensive overview of currently available experimental models used to investigate inherited cholesterol biosynthesis disorders, including genetically engineered animal models, patient-derived fibroblasts, immortalized and CRISPR/Cas9-edited cell lines, and induced pluripotent stem cell-based systems. Particular emphasis is placed on Smith-Lemli-Opitz syndrome, the most extensively studied disorder within this group, while recent advances in modeling desmosterolosis, lathosterolosis, and congenital hemidysplasia with ichthyosiform nevus and limb defects syndrome are also critically discussed. We compare the strengths and limitations of each experimental platform, highlighting their contributions to understanding sterol metabolism, developmental abnormalities, and cell-type-specific disease mechanisms. Finally, we discuss current challenges and future perspectives, including the development of patient-specific induced pluripotent stem cell models, genome editing approaches, and next-generation multicellular systems. Collectively, this review provides an updated framework for selecting appropriate experimental models to investigate cholesterol biosynthesis disorders and accelerate the development of mechanism-based therapeutic strategies.",
"42589549": "ID: 42589549\nTitle: Molecular Mechanisms Underlying Antimicrobial Resistance in Mycobacteria.\nAbstract: Antimicrobial resistance in mycobacteria arises from a complex interplay of intrinsic and acquired mechanisms that collectively limit the efficacy of current therapeutic options. Intrinsic resistance is largely driven by the low permeability of the mycobacterial cell envelope, the activity of efflux pumps, and the presence of drug-modifying enzymes, which together restrict intracellular drug accumulation and contribute to broad baseline tolerance. This review integrates resistance mechanisms of both M. tuberculosis and M. abscessus, two clinically relevant mycobacteria that share core molecular pathways while exhibiting species-specific determinants that complicate treatment. Additional intrinsic factors, including biofilm formation and stress-induced adaptive responses, further enhance persistence and reduce susceptibility to multiple drug classes. Acquired resistance predominantly results from chromosomal mutations affecting drug targets or prodrug activation pathways, such as katG, inhA, rpoB, gyrA, and pncA in Mycobacterium tuberculosis, leading to high rates of multidrug-resistant and extensively drug-resistant disease. In nontuberculous mycobacteria, species-specific determinants-including inducible macrolide resistance mediated by erm(41) in M. abscessus, plasmid-mediated erm (55) variants, rrl and rrs mutations, diverse enzymatic inactivation systems, and regulatory alterations in the MarR family that result in inducible resistance to drugs such as ethionamide -generate highly variable resistance profiles that complicate treatment. Recent advances in molecular diagnostics, including PCR-based assays, whole-genome sequencing, CRISPR-based diagnostic platforms, AI-assisted diagnostics, and emerging multi-omics approaches, have improved the detection of resistance-associated mutations and enhanced understanding of mycobacterial pathophysiology. In parallel, new therapeutic agents and optimized regimens offer promising avenues to overcome resistance, although emerging resistance to novel drugs underscores the need for continued surveillance. This review synthesizes current knowledge on the molecular basis of resistance in M. tuberculosis and NTM, highlighting implications for diagnosis, treatment, and future research.",

Prime editing enables precise genome modification without generating double-strand DNA breaks or requiring donor DNA templates. We established an in vitro prime editing workflow to generate and subsequently correct the mdx5cv mutation in mouse C2C12 myoblasts. Following optimization of engineered prime editing guide RNAs (epegRNAs) and PAM-flexible prime editors, wild-type cells were edited, clonally isolated, and genotyped. Mutation correction was then evaluated using optimized epegRNA designs. Two rounds of prime editing introduced the mdx5cv mutation into approximately 20% of alleles in C2C12 cells creating the mdx5cv C2C12 cell line. Clonal isolation yielded five homozygous mutant clones among 59 expanded colonies. Optimization studies identified an epegRNA containing a 16 nucleotide reverse transcription template and a 10 nucleotide primer binding site (RTT16/PBS10) as the most efficient design. Correction of the pathogenic allele reached approximately 26%, whereas longer PBS lengths reduced editing efficiency. In silico off-target analysis using Cas-OFFinder identified no candidate genomic loci with fewer than three mismatches for the spacer sequences used in either mutation generation or correction, suggesting a favorable predicted specificity profile. Corrected mdx5cv C2C12 myoblasts retained their capacity to differentiate into multinucleated myotubes. Representative Western blot analysis detected dystrophin protein expression in differentiated corrected mdx5cv myotubes, consistent with successful correction of the pathogenic mutation. These findings establish a robust prime editing platform for both the generation and correction of the mdx5cv mutation and provide proof of concept that precise correction of the pathogenic mutation is associated with restoration of dystrophin expression following myogenic differentiation.",

Mutations in tubulin genes can lead to tubulinopathies, a class of rare genetic neurodevelopmental disorders characterized by a range of brain malformations and other clinical features. Recent studies have shown that pathogenic variants in beta-tubulin genes such as TUBBG308S have been found to underlie the development of ciliopathies, disorders impacting cilia, important organelles for development and cell motility. Thus, mutations in distinct tubulin genes, which present a significant hurdle for the development of therapeutic gene editing strategies and targeted therapeutics. Here, we describe the development of a mutation-independent treatment strategy based on the upregulation of non-mutated beta-tubulin isotype protein using CRISPR-Cas9 activation. By increasing the expression of various beta-tubulin proteins, we demonstrate a restoration of the microtubule network and primary cilia formation.",
"42594274": "ID: 42594274\nTitle: Histone H3K27M variants determine myeloid subset dependencies and immune reprogramming in diffuse midline glioma.\nAbstract: Diffuse midline gliomas (DMGs) are highly aggressive, WHO grade 4 glial tumors that arise in midline central nervous system structures and are defined by K27M mutations in histone H3 genes. These K27M mutations shape intratumoral myeloid cell composition in DMG. In H3.1K27M DMGs, genetic ablation of monocyte recruitment reshapes the tumor microenvironment (TME) by reducing monocyte-derived macrophages (MDMs) and increasing microglia and neutrophil presence, with overall survival remaining unchanged, indicating compensatory myeloid remodeling is occurring. Here, by using CRISPR/Cas9-based genome editing, we generated a mouse model deficient for CCR1/CCR2/CCR3/CCR5 (\u03941235). Using this strain, we effectively abolished monocyte and MDM infiltration and reversed compensatory recruitment of CCR1+ neutrophils. Abolishing MDMs in tumors skewed remaining neutrophils and microglia toward a homeostatic state, reduced expression of immune checkpoint molecules on T cells, and extended the survival of H3.1K27M DMG-bearing mice. In contrast, H3.3K27M DMG showed independence from MDM recruitment, suggesting reliance on other TME-driven signaling. Last, H3.1K27M DMGs exhibited reduced microglia presence and a dose-dependent increase in MDM infiltration postirradiation. MDM depletion did not further enhance radiation efficacy, potentially due to compensatory recruitment of classical neutrophils. Collectively, these data reveal histone mutation-specific myeloid dependencies in DMG, highlighting MDM-independent mechanisms in H3.3K27M tumors and MDM-dependent pathways in H3.1K27M tumors.",
"42594811": "ID: 42594811\nTitle: Pcgf5 controls the exit from totipotency in mouse embryonic stem cells.\nAbstract: Mouse embryonic stem cell (ESC) cultures contain a rare subpopulation of two-cell-like cells (2CLCs) that transiently reactivate a two-cell embryo-like transcriptional program characteristic of zygotic genome activation (ZGA), including the endogenous retrovirus MERVL and Zscan4, and thereby regain a totipotent-like state. Polycomb repressive complex 1 (PRC1)-mediated H2AK119ub1 has been implicated in restraining entry into the 2C-like state through Pcgf6, yet the factors governing exit from this state and loss of totipotency remain poorly defined. Here, we show that among the six Pcgf paralogs, Pcgf5, which is most prominently upregulated in 2CLCs and forms an MERVL-driven chimeric transcript (Pcgf5MT2C_Mm) during ZGA in 2-cell embryos, controls exit from the 2C-like state in mouse ESCs. Using a reporter ESC line carrying MERVL-tdTomato and Zscan4c-EGFP (MtZG), we manipulated Pcgf5 dosage bidirectionally. Doxycycline (Dox)-inducible overexpression (OE) of Pcgf5 reduced the double-positive (DP) 2C-like population. Conversely, CRISPR-mediated knockout (KO) of Pcgf5 by targeting a common exon shared by all Pcgf5 variants (hereafter, total Pcgf5) increased the DP population. Time-lapse imaging directly confirmed that these changes reflected genuine differences in duration of the 2C-like state: OE shortened, whereas KO prolonged, the time cells spent in this state. These findings reveal that a Polycomb group factor controls not only entry into but also exit from the 2C-like state.",

We identify six negative regulators of delivery whose depletion increases editing efficiency by up to six-fold across diverse payloads, loci, and cell types. We test the top two factors, GJB2 and BET1L, in two distinct human models: correction of a pathogenic adenine base mutation in KCNJ13 and introduction of a cytosine base mutation in the GABAA receptor gene. Depletion of either improves base-editing outcomes by 6-fold, potentially through effects on delivery. In a patient-derived model of retinal channelopathy, knockdown of either gene improves lipid nanoparticle base editing efficiency by over 3.5-fold.

Conventional treatments, including immunotherapies and targeted inhibitors, face three main challenges: tumor heterogeneity, drug resistance, and systemic toxicity. Nucleic acid therapeutics (NATs) encompass a diverse array of DNA- and RNA-based tools, including small interfering RNA (siRNA), microRNA (miRNA), messenger RNA (mRNA), antisense oligonucleotides (ASOs), and clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) systems. These tools are central to developing precision oncology approaches that operate through direct gene regulation, mutation correction, and immune system reprogramming. The clinical application of NATs currently faces three main obstacles, which include their vulnerability to enzymatic degradation, their limited ability to penetrate tissues, and their tendency to cause off-target effects. The field has progressed through the implementation of nanoformulation techniques, which utilize lipid-based polymeric and metallic carriers together with exosomes and DNA origami, and hybrid nanostructures as new platforms to enhance the stability of drugs and their cellular absorption and targeted delivery to tumors. The scientists developed functionalized nanocarriers by combining targeting ligands with materials that could respond to specific environmental changes, which allowed them to manage drug distribution and release patterns throughout the tumor microenvironment. This review focuses on establishing a direct connection between nucleic acid design and nanotechnology through an analysis of mechanistic details and progress in preclinical and clinical research, and the difficulties encountered during the progress to practical applications. The research demonstrates how artificial intelligence and bioinspired nanocarriers and multi-omics data integration create new opportunities for developing personalized adaptive nanogenetic treatment methods, which will treat lung cancer. The current advancements indicate that we are approaching a transformative era in which nanomedicine and nucleic acid therapeutics will enable safe genetic alterations of cancer through targeted therapeutic applications.",

Rhesus induced pluripotent stem cells (RhiPSCs) derived from these monkeys present a unique opportunity for in vitro modeling and comparison with cells derived from MAPT R406W human carriers. Here, we report the development of a reproducible method to generate RhiPSCs compliant with the standards of the International Society for Stem Cell Research (ISSCR) to support in vitro modeling of FTD-MAPT R406W. Our stepwise approach identified efficient methods for fibroblast derivation, fibroblast reprogramming to RhiPSC, and RhiPSC maintenance over continued culture. To derive fibroblasts from MAPT wild type (WT) and R406W monkeys, a combination of manual processing and overnight enzymatic digestion was required to maximize the number of low passage fibroblasts available for reprogramming. Fibroblast reprogramming to RhiPSC using Sendai viral vectors versus oriP/EBNA1 episomal plasmids revealed the latter as most efficient. Electroporation conditions for oriP/EBNA1 reprogramming were optimized to maximize plasmid uptake and cell survival. Ultimately, eight RhiPSC lines were derived from 4 donor rhesus monkeys (n = 2 WT, n = 2 R406W; two clonal lines per donor) and fully characterized according to ISSCR standards. RhiPSC stemness and genetic stability was best maintained on mouse embryonic fibroblast feeders in Universal Primate Pluripotency Stem Cell medium, as opposed to Essential 12 medium supplemented with IWR1, which produced cytogenetic abnormalities. Rhesus neural progenitor cells were generated using a monolayer protocol and expressed PAX6 and NESTIN after 21 days of differentiation. Our reliable method will be useful to labs seeking to derive RhiPSCs for preclinical studies. Overall, the RhiPSCs generated from MAPT R406W carriers will be a critical resource for evaluating the molecular underpinnings of tau-related neurodegeneration across primate species.",

This review systematically summarises current fabrication strategies, disease-modelling utilities and regenerative potentials of liver organoids, alongside the major challenges and future directions. In recent years, the field has witnessed several breakthroughs. Through endothelial co-culture approaches, vascularised and metabolically zonated liver organoids have been successfully generated, achieving endothelial coverage exceeding 85%. Prime editing enables precise correction of pathogenic mutations in patient-derived organoids, with no off-target effects detected at the genome-wide level. In disease modelling, iPSC-derived liver organoids faithfully recapitulate the pathological progression of metabolic dysfunction-associated steatotic liver disease (MASLD) and verify the lipid-lowering efficacy of semaglutide. Macrophage-integrated organoid models support the full life cycles of HEV, SARS-CoV-2 and dengue virus, providing new tools for antiviral drug screening. Large-scale patient-derived tumour organoid biobanks successfully preserve the heterogeneity and clinical drug-resistance signatures of liver cancers. In regenerative medicine, encapsulated hepatocyte organoids and the UTOpiA bioartificial liver system have effectively rescued acute liver failure in animal models, while gene-edited autologous organoids offer potential curative strategies for genetic disorders such as Wilson disease. Nevertheless, insufficient hepatocyte functional maturity, difficulties in constructing vascular networks, and the lack of standardised culture protocols remain major obstacles to clinical translation.

This review synthesizes current advances aimed at enhancing the specificity of CRISPR diagnostics, with particular emphasis on the pivotal role of CRISPR RNA (crRNA) engineering. We detail how structural determinants of crRNA, including spacer length optimization, intentional mismatch design, secondary-structure modulation, chemical modification, strand-displacement gating, and synergistic design frameworks, govern CRISPR-mediated target recognition and define the energetic and kinetic thresholds for accurate cleavage. Key engineering strategies encompassing computational prediction and modeling, high-throughput screening, and hybrid guide architectures are systematically examined for their capacity to elevate single-nucleotide discrimination, stabilize reaction performance, and enable robust multiplexed detection for pathogen profiling and mutation identification. Despite rapid progress, outstanding challenges persist, including interference from complex clinical matrices, lack of unified evaluation standards, and scalability barriers that hinder clinical translation. Addressing these limitations through integrated crRNA design, system-level optimization, and standardized benchmarking will be essential for realizing the promise of CRISPR diagnostics.

Although gap larvae exhibit normal external morphology, gap mutants exhibit severe defects in adult organs, suggesting that the gap gene is required for the development of imaginal discs and the primordia of adult organs. Genetic analysis of the gap mutation provides an opportunity to understand the molecular mechanisms underlying the development of adult organs. In this study, we performed RNA-seq analysis of ovaries from gap mutants. De novo assembly of RNA-seq reads identified the insertion of a retrotransposon in the gene encoding the Bombyx ortholog of protein-cysteine N-palmitoyltransferase (Rasp), which is required for Hedgehog signaling in Drosophila. PCR and subsequent sequencing analyses revealed that an LTR transposon is inserted into exon 1 of the BmRasp gene. To verify the involvement of BmRasp in the gap phenotype, we generated a knockout allele of BmRasp (BmRaspKO) using the CRISPR/Cas9 system. Both homozygous knockout mutants and F1 pupae with the gap/BmRaspKO genotype exhibited gap-like phenotypes characterized by apterous pupa, indicating that BmRasp corresponds to the gap locus. To investigate why zygotic BmRasp expression is dispensable during embryogenesis but essential for the development of adult organs, we analyzed BmRasp expression levels in eggs and larval tissues. Furthermore, testis transplantation experiments demonstrated that BmRasp is dispensable for spermatogenesis, despite the fact that the testis exhibits the highest expression level of BmRasp among the tissues analyzed. Finally, we discuss the physiological roles of Hedgehog signaling in embryogenesis and in the development of imaginal discs in B. mori.",

Here, we establish the first comprehensive human mechanistic model of PPP1R9A haploinsufficiency using an isogenic CRISPR/Cas9-engineered iPSC system differentiated into cortical neurons to define dosage-dependent functional consequences. PPP1R9A+/- neurons exhibited pronounced hyperspinogenesis and increased neuritic complexity, indicative of aberrant structural maturation; however, whole-cell patch-clamp recordings revealed impaired intrinsic excitability, including reduced action potential firing, altered waveform properties, and defective axo-somatic coupling, uncovering a striking dissociation between neuronal morphology and function. Long-read single-cell transcriptomics and quantitative proteomics identified coordinated downregulation of ion channel and synaptic transmission pathways, including genes essential for sodium channel function and glutamatergic signaling, together with disruption of synaptic vesicle cycling, axon guidance, and neurodevelopmental programs. Pseudotime trajectory analysis further demonstrated delayed neuronal differentiation, with mutant neurons accumulating at intermediate developmental states rather than acquiring mature cortical identities. Importantly, molecular rescue experiments confirmed causality, as restoration of full-length PPP1R9A expression robustly normalized transcriptional and synaptic signaling programs, whereas allele-specific antisense oligonucleotide-mediated suppression of the mutant transcript achieved only partial rescue. Taken together, these findings establish PPP1R9A haploinsufficiency as a driver of impaired molecular, electrophysiological, and developmental maturation in human cortical neurons, providing a human-specific mechanistic framework linking reduced Neurabin I dosage to neurodevelopmental and psychiatric disease risk.",

We previously identified RNA viruses that infect the nematodes C. elegans and C. briggsae in a species-specific manner. Wild strains of both host species demonstrate ample variation in viral sensitivity. Here we use recombinant inbred lines and pool-sequencing approaches to genetically map a major resistance locus in the C. elegans MY10 strain, narrowing down its position by CRISPR/Cas9 mediated recombination and testing candidates by genome editing. A rare non-synonymous polymorphism in the gtnt-1 gene, encoding a putative glycosyltransferase of the GT92 family, causes resistance to viral infection in MY10. Loss-of-function gtnt-1 alleles conferred host protection only at late developmental stages, highlighting the importance of multigenerational assays capturing the full course of viral infection and transmission. Viral resistance through gtnt-1 mutation occurred repeatedly in C. elegans, with diverse alleles each remaining at low frequency (<1%). Furthermore, leveraging closely related C. briggsae strains differing in viral susceptibility, we find that repeated loss-of-function alleles of the Cbr-gtnt-1 ortholog similarly enhanced resistance and host fitness upon infection. In conclusion, recurrent evolution in two host species of loss-of-function alleles of gtnt-1 orthologs leads to viral resistance. The gtnt-1 gene being conserved between Caenorhabditis species, these repeated inactivation events provide a case of transient ecological adaptation to a pathogen through recurrent mutation of the same gene in two species. The low population frequencies of resistant alleles point to a changing eco-evolutionary context that prevents their spread in populations.",

In this study, we established a highly sensitive and specific assay by combining peptide nucleic acid (PNA)-mediated PCR clamping with CRISPR/Cas13a trans-cleavage detection. A PNA probe targeting the wild-type (WT) EGFR T790M allele was designed to suppress WT amplification during PCR, while minimally affecting mutant allele amplification. By combining the target specificity of Cas13a for mutant alleles with the WT-suppression capability of PNA-PCR, we achieved a dual-enrichment effect for mutant detection. When applied to EGFR T790M mutation detection, the assay reached an analytical sensitivity of 0.02%. We established a standard curve for T790M detection using cell-free DNA standards. Clinical validation in 20 plasma samples from lung adenocarcinoma patients demonstrated that the PNA-Cas13a assay achieved a diagnostic sensitivity of 93.3% (95% CI: 68.1%-99.8%) and a specificity of 100% (95% CI: 47.8%-100%), with detection concordance comparable to or improved over ARMS-PCR in this pilot cohort. The results suggest its preliminary diagnostic utility in liquid biopsy. In conclusion, the PNA-Cas13a assay enables sensitive and specific detection of EGFR T790M mutations in ctDNA, is readily adaptable to multiple gene loci, and holds promise for clinical monitoring of tumor drug resistance.",

MicroRNAs (miRNAs) have emerged as an essential post-transcriptional regulator of host-virus interactions, influencing viral replication, immunological responses and disease progression. This review offers a comprehensive overview of the miRNA-virus axis in RNA virus infections, highlighting the dynamic and context-dependent roles of host miRNAs. We investigate the mechanistic basis of miRNA-mediated regulation, including direct targeting of viral RNA, modulation of host dependency factors, regulation of antiviral signaling pathways, and immune-mediated effects on infection outcomes. We propose a functional categorization of miRNAs that transcends the conventional antiviral-proviral dichotomy, facilitating a more accurate comprehension of their involvement in various infection settings. This review connects mechanistic insights with translational applications by outlining novel treatment techniques, such as miRNA mimics, anti-miRs, RNA interference, and CRISPR-based methodologies. We also propose a therapeutic decision framework that links miRNA functional classification with targeted antiviral interventions. Key challenges including delivery efficiency, tissue specificity, and off-target effects are also discussed, with emphasis on lipid nanoparticles and exosome-based delivery systems. We further highlight the role of systems biology approaches, including multi-omics integration, single-cell and spatial transcriptomics, network analysis, and artificial intelligence, in identifying regulatory miRNA hubs and enabling precision antiviral medicine. Collectively, this review reinterprets the miRNA-virus axis as a dynamic regulatory network and provides a translational framework for the development of next-generation antiviral therapeutics.",

Although stable transformation in maize is no longer a major obstacle, there remains a need for accessible and efficient methods for academic laboratories. Here, we present the GGB\u00a0system, a rapid and efficient approach optimized for immature embryo transformation in B104 and other maize lines. This system combines two distinct morphogenetic regulators, the wheat GRF4-GIF1 chimera and the maize BABY BOOM (BBM) transcription factor (hence the name \"GGB\") with a modified QuickCorn protocol, enabling regeneration of transformed maize plantlets in c. 2 months with an efficiency 7-fold higher than when compared to either morphogenic factor used in isolation. Expression of both regulators did not significantly affect development, eliminating the need to excise them after regeneration. However, transmission of the transgenic GGB construct through pollen was significantly reduced, potentially aiding transgenic line containment. We show that the GGB system is adaptable for CRISPR-Cas9 editing and reporter line generation. Furthermore, stable GGB transformants exhibited high leaf regeneration capacity via somatic embryogenesis. RNA-seq time-course profiling of GGB leaf cultures identified additional factors that could promote regeneration and led to the discovery of asparagine and trehalose as additional media components that significantly enhanced leaf regeneration.",

While loss-of-function variants in SF3B2 have recently emerged as a genetic etiology, the molecular basis underlying this clinical heterogeneity remains poorly understood. Here, we report two probands harboring novel truncating SF3B2 variants and presenting with distinct clinical phenotypes. Proband 1, with a heterozygous p.(Gln60*) variant, exhibited characteristic CFM features, including mandibular hypoplasia, cleft palate, bilateral tragal abnormalities, microtia, external auditory canal stenosis with hearing impairment, and an epibulbar dermoid. In contrast, Proband 2, carrying a p.(Lys507*) variant, exhibited a milder craniofacial phenotype, although he had hearing loss and developmental delay that could not be explained with certainty by the SF3B2-variant. Western blot analysis demonstrated complete loss of p.(Gln60*) protein, whereas the p.(Lys507*) variant-despite lying outside the predicted nonsense-mediated decay (NMD) escape region-retained 15.5% residual expression of truncated protein. To investigate functional consequences, we performed CRISPR/Cas9-mediated sf3b2 knockout in zebrafish. Mutant larvae showed a 25.33% malformation rate and recapitulated human craniofacial features, including a reduced head-to-body length ratio (p\u2009=\u20090.0013), hypoplastic mandibular cartilage-evidenced by shortened Meckel's cartilage (p\u2009=\u20090.0104) and Palatoquadrate (p\u2009=\u20090.0174)-and impaired skeletal mineralization (p\u2009=\u20090.0028). Together, these findings suggest that truncating variants at different positions may be associated with differential protein expression levels and variable clinical presentations. Our study reinforces SF3B2's role as a loss-of-function disease gene and highlights the importance of variant-specific molecular characterization in understanding CFM.",

Different models, based on cultured cardiomyocytes, were proposed for the last 30\u2009years to explain the sequence of events. These were then evaluated during heart development in embryos in\u00a0situ and more recently in cardiomyocytes that were derived from human induced pluripotent stem cells (iPSC-CMs).

"42610742": "ID: 42610742\nTitle: Energetic Determinants of Expanded PAM Recognition in Engineered FnCas9.\nAbstract: Expanding protospacer-adjacent motif (PAM) compatibility while preserving specificity remains a central challenge in CRISPR-Cas9 engineering. Francisella novicida Cas9 (FnCas9) exhibits high intrinsic specificity but is constrained by stringent PAM requirements. Here, we quantitatively examine the energetic and catalytic consequences of PAM-interacting mutations in three engineered variants, en1 (E1369R), en15 (E1603H), and en31 (G1243T/E1369R/E1449H), using a VEGFA3 DNA substrate framework. Microscale thermophoresis and isothermal titration calorimetry reveal that the engineered variants enhance binding affinity toward the canonical NGG PAM relative to wild-type FnCas9, with modest gains in binding free energy. Selected noncanonical PAM substrates, particularly TGA and TAG, also show improved binding by en15 and en31, with en31 displaying the strongest overall binding among the substrates tested. Thermodynamic profiles indicate that enhanced affinity is associated with more favorable enthalpic contributions, consistent with altered interactions at the PAM interface; however, the specific molecular contributions underlying these changes remain to be directly established. Despite improved binding, active-site titration reveals reduced fractions of catalytically competent enzyme in engineered variants, particularly en31, necessitating higher enzyme concentrations to achieve cleavage efficiencies comparable to wild-type. Cleavage assays demonstrate that en31 most effectively couples improved recognition of the tested noncanonical PAM substrates to productive catalysis, enabling robust cleavage of both TGA and TAG substrates while maintaining minimal off-target activity under the conditions examined. Together, these results suggest that PAM-interacting mutations in FnCas9 can alter the energetic coupling between DNA binding and catalytic activation within the VEGFA3 substrate framework tested, highlighting the importance of balancing substrate affinity with conformational activation in the design of high-precision genome-editing nucleases.",
"42611132": "ID: 42611132\nTitle: A novel needleless delivery of Cas9 ribonucleoprotein complex in Bemisia tabaci embryos for gene editing.\nAbstract: The CRISPR/Cas9 system, particularly the Cas9-sgRNA ribonucleoprotein (RNP) complex, offers a highly efficient platform for gene editing. However, traditional microinjection methods for RNP delivery in insect embryos are labor-intensive, technically demanding, and often reduce embryo viability, especially in species with fragile, microscopic embryos. In this study, a novel, non-invasive delivery method for the RNP complex in tiny insect embryos has been optimized. Whitefly, Bemisia tabaci, an invasive insect pest of agricultural importance and vector of plant diseases, was considered as a model organism. A needleless dechorionation-permeabilization method was employed to deliver the RNP complex to the early embryonic stage of B. tabaci embryos. B. tabaci heat shock protein 70 (hsp70) gene, which interacts with the begomovirus coat protein, aiding in its internalization and successful transmission by B. tabaci in a persistent circulative manner, was targeted for knockout. Two sgRNAs were synthesized via in vitro transcription, and the Cas9-sgRNA complexes were validated by in vitro cleavage assays. The localization of the GFP-labelled Cas9-sgRNA complex confirmed successful RNP delivery, as observed through confocal microscopy. A survival rate of 18% of the embryos was recorded post-RNP delivery. Sequencing of treated embryos showed 25- and 28-nucleotide deletions in the hsp70 exon. Synthego ICE analysis revealed up to 84% gene knockout efficiency. This method enables batch processing of embryos, drastically reducing delivery time and associated costs while improving throughput. Hsp70 KO B. tabaci mutants generated in the study are expected to be incompetent begomovirus transmitters, which would help restrict the spread of the virus. Our study overcomes a key bottleneck in CRISPR/Cas delivery to small insect embryos, opening new avenues for rapid, high-throughput, and cost-effective RNP delivery methods in insect embryos. The novel non-invasive methods would be helpful in the deployment of gene editing for sustainable pest control.",

Taking advantage of the single-guide RNA (sgRNA) and protospacer adjacent motif (PAM) sequence (3'-NGG) specificity of the Cas9 protein in the CRISPR/Cas9 (Clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9) system and codon degeneracy, the authors design a repair template that incorporates the desired point mutation while excluding the PAM sequence disrupted by a synonymous substitution, thereby preventing re-cleavage by CRISPR/Cas9. This method employs two available plasmids, pCasKP-apr and pSGKP-spe, offering straightforward operation and high screening specificity. As a result, the approach enables efficient generation of genetically defined mutant strains of Klebsiella pneumoniae (K. pneumoniae) and is readily adaptable to routine laboratory settings. Furthermore, the protocol minimizes off-target editing, shortens experimental timelines, reduces screening workload, and provides a reliable platform for investigating resistance mechanisms, validating candidate genes, and supporting functional genomics studies in clinically relevant bacterial pathogens.",

Beyond direct cytotoxicity, this photochemistry can be repurposed for on-demand cargo release from lipid nanocarrier systems, enabling spatiotemporal control over therapeutic delivery that is not achievable with conventional lipid nanoparticles. This protocol presents methods for fabricating and characterising two distinct verteporfin (VP)-integrated lipid nanoparticle formulations: (1) light-triggered liposomes composed of DOTAP, DOPE, cholesterol, and VP for delivery of CRISPR-Cas9 ribonucleoprotein (RNP) complexes; and (2) X-ray-triggered liposomes composed of DOTAP, DOPC, VP, and gold nanoparticles for controlled chemotherapy drug release. Upon activation at 690 nm (visible light) or by clinical X-ray radiation (6 MeV), VP generates singlet oxygen that oxidises unsaturated lipid components, destabilising the nanoparticle membrane and releasing encapsulated cargos. Protocols are provided for liposome formulation by thin-film hydration and membrane extrusion, physicochemical characterisation, light- and X-ray-triggered cargo release assessment, in vitro gene knockout in human cells, and in vivo validation using a quantitative zebrafish visual reporter system and a mouse xenograft tumour model. Representative results demonstrate knockout of up to approximately 326 slow-muscle fibres per zebrafish embryo via light activation and significant tumour growth suppression via X-ray-triggered doxorubicin release.The clinical precedent for 689-690 nm verteporfin activation in the eye motivates evaluation of this platform for ophthalmic delivery, although retinal biodistribution, pharmacokinetics, and large-animal safety remain to be established.

Reliable generation of defined neuronal populations, such as gamma-aminobutyric acid (GABAergic) neurons, is essential for these studies. This protocol details a robust method for differentiating hiPSCs into GABAergic neurons using a doxycycline-inducible system. The approach relies on the stable integration of transgenes encoding the transcription factors ASCL1 and DLX2 into the safe-harbor adeno-associated virus integration site 1 (AAVS1.) locus via CRISPR/Cas9-mediated knock-in. This targeted integration avoids the transgene silencing often observed with random lentiviral integration. The protocol covers the maintenance of hiPSCs, the nucleofection process for transgene integration, puromycin selection to enrich successfully engineered cells, and the step-by-step differentiation procedure. Upon induction with doxycycline, the engineered hiPSCs rapidly exit the cell cycle, acquire neuronal morphology, and express GABAergic lineage markers within 21 days. Key steps include neuro-induction and subsequent maturation using specific growth factors, as well as potential approaches to improve cellular adhesion during maturation. This standardized method yields enriched populations of induced neurons expressing GABAergic lineage markers, providing a valuable tool for neuroscience research and cellular modeling.",

Editing outcomes are commonly evaluated in cultured primary cells, patient-derived cells, or engineered cell lines to study the impact of genetic variation or as a first step before initiating animal studies or clinical translation. Delivery of editors as mRNA together with synthetic guide RNAs into mammalian cells can improve editing efficiency relative to plasmid-based approaches and prevent issues such as DNA integration or off-target editing from sustained expression. This article presents a workflow to prepare genome editor mRNA by in vitro transcription (IVT), including co-transcriptional capping and chemically-modified nucleotides, electroporate editor mRNA and guide RNAs into primary human fibroblasts, induced pluripotent stem cells (iPSCs), or lymphoblastoid cell lines (LCLs), and quantify editing outcomes by targeted amplicon sequencing on an Illumina platform followed by analysis using CRISPResso2.

Based on extensive genotyping data of the asexually produced progenies of successfully edited females, we find strong evidence of mosaicism in 9 of these genes.

These conditions impose long-term health challenges on children, despite many advancements with conventional medicine. Although conventional treatments increase life expectancy and provide better disease control, many present challenges such as toxicity, insufficient control of the disease, and adverse effects on normal growth, development, and quality of life. Many researchers have shown increased interest in using stem cell therapies as an alternative to current medications to allow for complete, sustainable repair of damaged tissues and modification of disease processes (i.e., using stem cells to regenerate tissue or change the way in which a disease occurs). This paper will provide the current information on stem cells used in the treatment of children and the many different types of stem cells, including: hematopoietic stem cells (and their derivatives), mesenchymal stem cells (and their derivatives), induced pluripotent stem cells, embryonic stem cells, tissue-specific progenitor cells, extracellular vesicles, and bioengineered products. This paper will also discuss what is known about the stem cells listed as well as their methods of action, where they might currently be better utilized, and future uses of these cells in children for a variety of types of pediatric diseases. Because each stem cell type listed has very different scientific background and clinical evidence, there is much variability in the amount of scientific evidence available to support stem cell therapies. For example, hematopoietic stem cell transplantation (HSCT) has over 50 years of clinical experience; thus, there are many studies defining the clinical efficacy and long-term outcomes associated with HSCT. Conversely, while there are many published studies supporting the use of mesenchymal stem cells (MSCs), extracellular vesicles (EVs), gene-edited cells, organoids, and many induced pluripotent stem cell-derived therapies, more evidence (clinical and basic science) is still needed to fully establish efficacy for the use of these various stem cells in children with pediatric diseases. In addition to needing more clinical evidence, stem cell-based therapies face many important challenges to the advancement of these therapies, including (but not limited to) long-term safety assessments, manufacturing standardization, regulatory oversight, ethical concerns, and equitable access to advanced therapies. Addressing these challenges will be important for future advances in the use of regenerative medicine in pediatric patients which will also require the rigorous evaluation of new stem cell therapies, the continued improvement of translational mechanisms, and the ongoing incorporation of new techniques (e.g., genome editing, organoid modeling, EV therapeutics, bioengineering, and artificial intelligence) to advance regenerative medicine and demonstrate its value through safe and reproducible clinical trial results.",

Ex vivo CRISPR-Cas9 editing of autologous CD34-positive hematopoietic stem and progenitor cells to reactivate fetal hemoglobin has produced durable freedom from severe vaso-occlusive crises in SCD and sustained transfusion independence in TDT. This approach offers a donor-independent alternative to allogeneic hematopoietic stem-cell transplantation without graft rejection or graft-versus-host disease. Hemoglobinopathies, therefore, provide the first clinically validated delivery model for CRISPR therapeutics. Successful implementation, however, requires more than editing efficacy. It depends on structured referral, candidacy assessment, organ function review, mobilization and collection, centralized manufacturing, pharmacokinetic-guided myeloablative conditioning, transplant-level supportive care, fertility preservation, psychosocial support, and prolonged surveillance coordinated among primary hematologists and cellular therapy programs. Key barriers include stem cell collection, conditioning-related toxicity, cost, reimbursement friction, and persistent inequities in access. Long-term follow-up and registry participation are necessary to evaluate outcomes beyond pain crises, identify late toxic effects, and compare real-world effectiveness across gene editing, gene addition, and allogeneic transplantation. In oncology, CRISPR-based therapy remains investigational, with early clinical feasibility demonstrated in relapsed or refractory B-cell malignancies, T-cell malignancies, AML, multiple myeloma, and selected solid tumors. For hematologists, oncologists, and transplant and cellular therapy programs, the central challenge is to integrate CRISPR into practice with the rigor required for any high-risk curative therapy: careful patient selection, disciplined delivery, and long-term accountability.",
"42620346": "ID: 42620346\nTitle: APP Dosage and Extracellular Domain Variants Drive Distinct Defects in Neurogenesis modeled in Down Syndrome iPS cells.\nAbstract: The amyloid precursor protein (APP) is heavily studied as the source of amyloid beta in Alzheimer's disease (AD), however, the complex functions of APP remain poorly understood, as does the impact of APP dosage on neurodevelopment. Here we study APP specifically in the context of Trisomy 21. In an effort to reduce APP dosage in trisomy 21 iPSCs, we generated trisomic isogenic lines which vary in APP dosage, including a full APP knock-out line, as well as lines carrying mutations of the APP extracellular domain. We used a panel of these lines to study potential impacts of APP dosage or structure on two distinct steps of neurogenesis in trisomic cells: 1) terminal differentiation of human neuro-progenitor cells (NPC) to post-mitotic neurons and 2) neuron structure as reflected in neurite outgrowth. Complete loss of APP causes marked defects in each of these two distinct steps, reducing both the terminal differentiation of NPCs to neurons, and proper neurite development for extended neuron structure. Hence, APP is necessary for both aspects of normal neurogenesis. Further analyses of the null and other mutant lines indicate that APP likely impacts these two distinct steps by two different mechanisms. Collective results suggest that the reduced terminal differentiation of NPCs reflects an effect of APP dosage, whereas the defects in neurite extension are due to structural mutation of the APP extracellular domain. Absence of APP or reduced (monosomic) APP dosage prolonged the cycling of trisomic NPCs, which is known to be regulated by Notch signaling. APP and Notch are the main targets of gamma-secretase cleavage, hence we hypothesized that APP dosage may impact neurogenesis indirectly, potentially via effects on Notch signaling. To test this, we treated NPCs with Compound E which inhibits gamma-secretase (and Notch signaling); results show this restored levels of neurogenesis in APP depleted lines, supporting an indirect effect of APP dosage . In contrast, results indicate that disruption of APP extracellular domain integrity impacts neurite extension via a more direct role of APP in neuron structural maturation. This study describes a resource of well-characterized APP mutant isogenic DS iPSC lines, implicates a dynamic interplay between APP dosage and Notch signaling, and raises new questions about the impact of APP dosage in orchestrating neural progenitor fate decisions during human brain development, specifically in the context of trisomy 21.",

(Lepidoptera: Bombycidae).\nAbstract: The Bombyx mori L. (Lepidoptera: Bombycidae) is a significant economic insect used for silk production. A novel body shape mutant, stony^sunken (st^sk), that exhibits a sunken intersegmental membrane was isolated from the wild type of st^sk (WT-n08). Investigation indicated that the mutation had no significant effect on its growth and development. To elucidate the molecular mechanism underlying this body shape mutant, genetic analysis, positional cloning, and the CRISPR/Cas9 gene editing system were performed. Genetic analysis demonstrated that the mutant trait in st^sk is controlled by an autosomal recessive gene and follows Mendelian inheritance. Positional cloning showed that a putative cuticular protein gene, BmorCPR2 on chromosome 8, was the candidate gene. Sequencing analysis revealed partial deletion of BmorCPR2 exon 2 and intron 2 sequences occurred and subsequently resulted in the premature termination of gene expression. Knock-out of BmorCPR2 using the CRISPR/Cas9 gene editing system led to the sunken intersegmental membrane phenotype. These findings highlight the essential role of BmorCPR2 in silkworm cuticular formation, providing a foundation for further research on cuticular protein function.",

It may act in a very disparate manner; ranging between slow growing, well differentiated tumours to an aggressive anaplastic subtype. Initial treatment with standard therapy, surgery, radioactive iodine, the thyroid-stimulating hormone inhibition and in some cases, chemotherapy or external-beam radiations are effective with the differentiated cancers at the early stages. Nevertheless, there is no choice with tumours, which become unresponsive to iodine, metastasized, or un- differentiated. Recent developments in molecular oncology have elucidated the genetic alterations that contribute to thyroid cancer, in particular, the MAPK and PI3K/AKT/mTOR pathways, and BRAF, RAS, RET, and TERT promoter mutations. The current review summarizes the changing therapeutic environment of thyroid cancer that includes established targeted medicines and novel developments. These are immune checkpoint inhibitors, redifferentiation based on reinstatement of iodine uptake, selective RET and BRAF/MEK, RNA-based therapeutics, CRISPR gene editing, oncolytic virotherapy, peptide receptor radionuclide therapy, alpha-particle radiotherapy, and nanotechnology-based drug delivery systems. A combination regimen involving molecular targeting and immunotherapy or radioactive iodine is also improving the disease in advanced disease. Collectively, the advances are an indication of a transition to the personalized, mechanism-driven treatment strategies that would prolong the survivability of patients with advanced thyroid cancer, conquer resistance, and reduce systemic toxicity.",

Current reliance on porcine primary fibroblasts for genome editing is limited by low inefficiency in complex gene editing and difficulties in immunophenotyping edited cells. In this study, we demonstrate that porcine expanded potential stem cells (pEPSCs), derived from preimplantation embryos, provide a robust and versatile platform for generating donor cells for xenotransplantation. These pluripotent cells can differentiate into both embryonic and extraembryonic lineages, maintain genetic stability through multiple edits, and enable precise genome modifications. We performed multiple gene knockouts in pEPSCs targeting key immune rejection genes and precisely inserted a genetic cassette to facilitate streamlined introduction of human cDNAs via cassette exchange. The engineered pEPSCs retained their pluripotency and stability even after multiple rounds of genome editing. When differentiated into endothelial cells, they exhibited high immunogenicity, serving as a rapid and quantitative platform for immune response assessment. Importantly, the edited endothelial cells exhibited substantially reduced immunogenicity, confirming the functional impact of the genetic modifications. Although we have not yet generated live pigs from these gene-edited pEPSCs via somatic cell nuclear transfer (SCNT), our findings establish pEPSCs as a novel and improved platform for generating genetically engineered pig donors and for functionally evaluating genetic modifications, thereby advancing the prospects of xenotransplantation.",
"42625528": "ID: 42625528\nTitle: Four new Duchenne muscular dystrophy mouse models with clinically relevant exon deletions in the human DMD gene.\nAbstract: Mutation specific therapeutic approaches, like exon skipping or gene-editing, hold promise for the treatment of Duchenne muscular dystrophy (DMD). Translatability of preclinical studies investigating these approaches could greatly be improved through the use of humanized mouse models, as these allow preclinical testing of human specific sequences. We developed four novel humanized DMD mouse models with either a deletion of exon 44, 45, 51 or 53 in the human DMD gene, in a mouse dystrophin negative background (mdx mouse; exon 23 nonsense mutation). Our optimized prescreening pipeline allowed us to do so very efficiently with the CRISPR-Cas9 technology. We confirmed either complete lack of dystrophin, or expression of trace levels, which led to development of muscle pathology consisting of muscle fiber de-, and regeneration, inflammation and fibrosis in young adult mice. Intramuscular treatment with vivo-morpholinos targeting a flanking exon induced exon skipping in the DMD strains, which restored the disrupted open reading frame and subsequently dystrophin expression. This validates these models as valuable tools for preclinical studies investigating human sequence specific therapeutic approaches for DMD.",
"42626030": "ID: 42626030\nTitle: Mutation-Immune Crosstalk Contextualizes CAF-Associated ARPC1A Programs and Cisplatin Response in Gastric Cancer.\nAbstract: Cisplatin response in gastric cancer is shaped by malignant cell programs, stromal states, and mutation-immune crosstalk, but the CAF subtypes linked to platinum tolerance and their epithelial effectors remain incompletely defined. We integrated single-cell RNA sequencing, epithelial CNV-like inference, fibroblast reclustering, CellChat analysis, signature scoring, hdWGCNA, CAF-epithelial coupling, exploratory GSE14209 evaluation, TCGA-STAD mutation/copy-number contextualization, and DepMap CRISPR virtual knockout analysis, followed by experimental validation in AGS and HGC-27 cells. IGF1+ CXCL12+ CAFs showed resistance-supportive stromal features, and CAF-epithelial coupling prioritized ARPC1A as a tumor epithelial candidate associated with this stromal program. In TCGA-STAD, ARPC1A mutations were rare and consisted of three missense and two frameshift variants without a recurrent hotspot; the mutant tumors were confined to the MSI subtype and showed an immune-activated, high TMB/MSI context, indicating mutation-immune crosstalk rather than a clear mutation-specific CAF, EMT, drug resistance, or cisplatin response phenotype. By contrast, ARPC1A copy-number gain/amplification was more frequent and tracked with ARPC1A expression, CIN enrichment, aneuploidy, and fraction of genome altered. DepMap CRISPR data indicated mostly weak-to-mild baseline ARPC1A dependency in upper GI and gastric/GEJ models. Experimentally, ARPC1A knockdown increased cisplatin sensitivity, promoted cisplatin-induced apoptosis, and suppressed migration and invasion. These findings identify a CAF-associated ARPC1A epithelial program linked to cisplatin response and support a mutation-immune/copy-number framework in which ARPC1A is interpreted mainly through immune-contextual mutation patterns and expression dosage rather than recurrent gain-of-function mutation.",
"42628204": "ID: 42628204\nTitle: Blocking the conversion of \u03b2-carotenoids into xanthophylls through HYb gene editing via CRISPR/Cas9 confers enhanced heat stress tolerance in Nicotiana tabacum.\nAbstract: Plants produce protective metabolites to withstand stress, and \u03b2-carotenoids act as crucial antioxidants. \u03b2-Carotene is converted into xanthophylls by \u03b2-carotene hydroxylase (BCH). In this study, the BCH gene in Nicotiana tabacum was targeted using CRISPR/Cas9 genome editing to redirect metabolic flux toward \u03b2-carotene accumulation and evaluate its effects on heat tolerance. Following Agrobacterium-mediated transformation with a BCH-specific gRNA, three mutant plants were obtained; two carrying frameshift mutations (P1 and P3) and one with mis-sense mutations (P2). A significant increase in chlorophyll contents was observed in the edited lines compared with wild-type plants. Interestingly, the frameshift mutants exhibited substantial increase in total chlorophyll (71% and 31% in P3 and P1 respectively) as compared to mis-sense mutant P2 (18%). Further, biochemical profiling using HPLC showed that the edited plants accumulated 3.74-fold increase in \u03b2-carotene than wild-type plants. Under heat stress (42\u202f\u00b0C for 96\u202fh), the edited plants exhibited enhanced thermotolerance by remaining greener and delayed wilting, whereas wild-type plants developed necrosis rapidly under heat stress. This enhanced thermotolerance might has resulted from the increased expression of \u03b5-cyclase (an upstream key enzyme in \u03b2-carotene biosynthesis) as revealed by expression profiling of edited plants. In contrast, the expression of downstream \u03b2-cryptoxanthin and zeaxanthin biosynthetic genes was reduced, which seems consistent with mutation of BCH. DAB staining further confirmed reduced ROS accumulation in edited plants as compare to wild type supporting the protective role of \u03b2-carotene. In summary, the downregulation of BCH in N. tabacum boosted \u03b2-carotene levels and chlorophyll retention, enhancing heat stress tolerance. These findings demonstrate the potential of targeting carotenoid biosynthesis to improve crop resilience.",
"42628215": "ID: 42628215\nTitle: Evaluation of germline transmission of electroporation-mediated double gene-edited cattle lines.\nAbstract: Gene editing in livestock using clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) offers a promising approach for genetic improvement in cattle. This study evaluated germline transmission and mutation stability of double-knockout cattle generated by zygote electroporation. Previously reported myostatin/beta-lactoglobulin (MSTN/BLG) and newly generated \u03b1-1,3-galactosyltransferase (GGTA1/BLG) double-knockout cattle were produced using CRISPR/Cas9-mediated genome editing. Targeted deep sequencing demonstrated extensive somatic mosaicism across multiple tissues. Computer-assisted sperm analysis (CASA) demonstrated normal sperm motility in MSTN/BLG double-knockout males. Fertilization of wild-type oocytes produced heterozygous embryos, with mutation frequencies of 37.76\u202f\u00b1\u202f10.74% at the MSTN locus and 54.80\u202f\u00b1\u202f7.73% at the BLG locus, as assessed by T7 endonuclease I (T7E1) assay. MSTN/BLG double-knockout sperm were subsequently used for embryo production and for artificial insemination of GGTA1/BLG double-knockout females. Healthy offspring were successfully obtained (n\u202f=\u202f3), alongside one stillborn calf. Targeted deep sequencing of all four progenies revealed highly variable allele frequencies that deviated substantially from the approximately 50% expected for heterozygous germline transmission. In contrast, whole-genome sequencing (WGS) results were consistent with Mendelian expectations, underscoring the limitations of PCR-based targeted sequencing for assessing germline transmission in mosaic founders. These results show that CRISPR/Cas9-edited embryos generated by electroporation can develop into healthy, sexually mature cattle capable of germline transmission. While variable transmission rates were observed owing to founder mosaicism, non-mosaic F1 offspring were successfully generated. However, direct, embryo-mediated gene-editing strategies remain technically and economically challenging for large-scale commercial calf production, and reports in cattle are limited. This study provides a reference for future applications of gene-edited embryos and their germline propagation.",
"42628531": "ID: 42628531\nTitle: Historical metabolic adaptation potentiates the rapid evolution of flonicamid resistance in Myzus persicae.\nAbstract: Rapid adaptation to novel environments is often shaped not only by newly acquired mutations but also by historical genetic backgrounds established through prior evolutionary events. However, the extent to which such historical contingency contributes to the rapid evolution of insecticide resistance remains poorly understood. Here, we investigated the emergence of resistance to flonicamid, a recently deployed insecticide, in the green peach aphid, Myzus persicae. We show that constitutive overexpression of the P450 enzymes CYP6CY3 and CYP6CY4, already widespread in populations of M. persicae before flonicamid deployment, confers a previously cryptic tolerance phenotype to flonicamid. However, biochemical and transgenic analyses demonstrated that these metabolic adaptations provide only weak protection against flonicamid. Following flonicamid deployment, however, a novel target-site mutation, NaamV251I, in the recently identified molecular target of 4-trifluoromethylnicotinamide (TFNA-AM), emerged in M. persicae on a genetic background of CYP6CY3 or CYP6CY4 overexpression. Structural modeling, enzymatic assays, and CRISPR-Cas9 genome editing demonstrated that this mutation reduces target sensitivity and independently confers moderate resistance. Strikingly, combining the nicotinamidase (Naam) mutation with pre-existing CYP6CY3 or CYP6CY4 overexpression produced substantially elevated resistance phenotypes that far exceeded the effects of either mechanism alone. Our results demonstrate that the pre-existing metabolic background did not itself evolve further following flonicamid deployment but fundamentally altered the phenotypic consequences of a subsequently acquired target-site mutation. These findings provide direct evidence that historical adaptive variation can potentiate rapid resistance evolution to newly introduced insecticides and reveal how interactions between past and contemporary adaptations shape evolutionary responses to novel environmental challenges.",
"42630431": "ID: 42630431\nTitle: Direct neuronal reprogramming for neurological diseases: applications, translational Challenges, and future directions.\nAbstract: Neurological diseases, often caused by irreversible loss of terminally differentiated neurons, present considerable challenges to treatment due to the limited regenerative capacity of these neurons. Although induced pluripotent stem cells hold promise for neuronal regeneration, their clinical application is constrained by risks, including tumorigenicity, incomplete neuronal maturation, and immune rejection. Recent advancements in direct neuronal reprogramming, which bypasses the intermediate pluripotent stage by directly converting non-neuronal cells into functional neurons, offer a compelling alternative for in situ neuronal replacement in neurodegenerative diseases. Key transcription factors, such as NeuroD1, Ascl1, Sox2, as well as CRISPR activation (CRISPRa) of NGN2 and ISL1, have been explored to convert glial cells into neurons. However, several challenges remain. This review discusses the current applications of direct neuronal reprogramming technology in several neurological diseases. We further highlight the potential contamination issues in adeno-associated virus (AAV) delivery systems and propose a code of conduct to avoid artifacts and pitfalls. Finally, we point out future directions for expanding direct reprogramming targets, integrating organoid-based disease modeling, and advancing reprogramming regulation techniques.",
"42630992": "ID: 42630992\nTitle: Regulating human reproductive and developmental biotechnologies: a UK reference model.\nAbstract: Rapid scientific change is exposing the limits of the UK's regulation of human reproductive and developmental biology. Embryo-like structures, in vitro gametogenesis, organoids and heritable genome editing advance understanding of human development and physiology and support new applications in assisted reproduction and clinical care, yet the current regulatory framework is ill-equipped to govern them coherently. A case is made for coordinated, technology-neutral regulatory change. The article proposes the principles of a model UK Human Reproductive and Developmental Biotechnology Act and regulator, the Human Reproductive and Developmental Biotechnology Authority-or HRBA, pronounced 'harbor'-to provide a permissions route across research and translation. The model Act is a modular, risk-tiered scheme with consistent standards and tailored red lines. It is designed to accommodate boundary cases, to integrate and build upon the existing remit of the Human Fertilisation and Embryology Authority, and coordinate with other established regulators to retain institutional expertise and avoid unnecessary duplication. The proposal is ambitious and would help give effect to UK Government commitments to safely advance the life sciences in this area. But even if piecemeal amendments are ultimately favored, it clarifies the underlying choices and trade-offs and provides a benchmark against which changes can be tested.",
"42635115": "ID: 42635115\nTitle: One-pot SP-EXPAR-integrated CRISPR/Cas14a assay for highly specific and versatile detection of ctDNA mutations in lung cancer patients.\nAbstract: The highly specific and versatile detection of KRAS mutations in circulating tumor DNA (ctDNA) from plasma has critical clinical implications for non-small-cell-lung cancer (NSCLC). However, conventional isothermal amplification methods suffer from poor single-base discrimination, while CRISPR-12a-based detection is highly protospacer adjacent motif (PAM)-dependent. To address these challenges, a one-pot self-primer isothermal exponential amplification reaction (SP-EXPAR) combined with a CRISPR/Cas14a assay was developed for detecting KRAS G12C and G12D. Two synergistic strategies were devised to ensure high specificity: first, a carefully designed hairpin probe that permits selective amplification of mutant over wild-type sequences through differential binding affinity; second, optimization of the Cas14a sgRNA seed region, with the mutation positioned at the 11th nucleotide for stringent target recognition. The assay is further distinguished by a physical separation design, in which the Cas14a reagents are pre-loaded into the tube cap and mixed with the amplification products only after SP-EXPAR completion. This assay enables KRAS G12C detection within 1 h, with a limit of detection of 81.9 aM (0.1% mutation percentage) and a dynamic range from 100 aM to 1 nM. Furthermore, this assay further demonstrates its programmability and was successfully applied to detect KRAS G12D with comparable performance. In detecting 42 clinical samples, this assay demonstrated 100% sensitivity and 100% specificity compared with DNA sequencing. This approach holds great potential in disease diagnosis."
