However, its high polymorphism poses challenges for accurate genetic profiling using conventional reference genomes. Here, we present high-quality, haplotype-resolved assemblies of the MHC region in five widely used tumor cell lines: A549, HeLa, HepG2, K562, and U2OS. Numerous oncological studies extensively employ these cell lines, ranging from basic molecular research to drug discovery and personalized medicine approaches. By integrating CRISPR-based targeted enrichment with 10 × Genomics linked-read and PacBio HiFi long-read sequencing, we constructed MHC haplotypes for each cell line, providing a valuable resource for the research community. Using these assembled haplotypes as references, we characterize the aneuploidy of the MHC region in these cell lines, offering insights into the genetic landscape of this critical immunological locus. Our work addresses the urgent need for accurate MHC profiling in these widely used cell line models, enabling more precise interpretation of existing and future genomic and epigenomic data. This resource is expected to significantly enhance our understanding of tumor biology, immune responses, and the development of targeted therapies.</div></div>","PeriodicalId":12689,"journal":{"name":"Genes & Diseases","volume":"12 5","pages":"Article 101603"},"PeriodicalIF":6.9,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, amylin can form aggregates in the brain, promoting β-amyloid deposition and tau phosphorylation in Alzheimer's disease. The cross-seeding between amylin and tau exacerbates tau pathology spread and synaptic loss, leading to neurodegeneration and cognitive deficits. Given the link between lysosomal dysfunction and tauopathy in the brain and amylin aggregation in the pancreas, we hypothesized that amylin could potentially worsen tau pathology in diabetic mice. We administered streptozotocin and/or amylin peripherally to the PS19 model of tauopathy at 3 months and characterized them at 6 months of age. We found that streptozotocin diminished body weight gain, increased blood glucose levels, worsened motor performance, and improved fear-conditioned memory in PS19 mice. Both amylin and streptozotocin administration prompted the emergence of tau pathology in the pancreas, which coincided with a decrease in the number of lysosomes in pancreatic islets. Mice treated with amylin and streptozotocin also developed robust tau pathology concomitant with lowering lysosomal cathepsin D levels in the visual cortex. These findings suggest that in diabetic mice, amylin administration diminished pancreatic lysosomes, possibly increasing the number of amylin aggregates that reached the brain and contributing to the worsening of tau pathology due to lysosomal impairment in the visual cortex. The outcome of our research enhances the understanding of the cellular pathways by which amylin may serve as a link between the pancreas-brain axis during diabetes, influencing the risk of developing tau pathology.</div></div>","PeriodicalId":12689,"journal":{"name":"Genes & Diseases","volume":"12 5","pages":"Article 101602"},"PeriodicalIF":6.9,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144322051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its neurotoxicity has been extensively studied, and recent research has revealed that it can also lead to abnormal spermatogenesis. However, the factors and molecular mechanisms involved remain unclear. In this study, male Sprague–Dawley rats were gavaged with different concentrations of CPF for 30 days, resulting in a disrupted blood-testis barrier (BTB) and abnormal spermatogenesis. RNA sequencing analysis of Sertoli cells, the primary components of the BTB and key targets of environmental toxins, revealed that ferroptosis-related genes were predominantly among the differentially expressed genes. The expression of ferroptosis-related markers was up-regulated, malondialdehyde and Fe<sup>2+</sup> levels were elevated, and glutathione levels were reduced in CPF-exposed testicular tissue and its metabolite TCP-exposed Sertoli cells, confirming that CPF exposure triggered ferroptosis in testes and Sertoli cells. Moreover, treatment with ferrostatin-1, a ferroptosis inhibitor, restored Sertoli cell junctional function. Given the important roles of clockophagy and the HIF-1α pathway in ferroptosis, we investigated the activity of clockophagy in testes and Sertoli cells. Unexpectedly, clockophagy activity was found to be enhanced by the significantly reduced expression levels of ARNTL and HIF-1α following CPF and TCP exposure. Notably, <em>Arntl</em> knockdown impaired Sertoli cell junctional function. Collectively, these findings strongly indicate that CPF induces ferroptosis in Sertoli cells through activating clockophagy, resulting in the decreased expression of HIF-1α and BTB-associated proteins; this ultimately leads to the disruption of BTB integrity and spermatogenesis dysfunction.</div></div>","PeriodicalId":12689,"journal":{"name":"Genes & Diseases","volume":"12 5","pages":"Article 101601"},"PeriodicalIF":6.9,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144366327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expression and promoter methylation of NKAPL were examined by real-time PCR, quantitative PCR, and methylation-specific PCR. The functional impacts of NKAPL on NSCLC proliferation were explored by CCK8 assay and colony formation assay. Transwell assay was conducted to investigate the role of NKAPL in NSCLC cell migration and invasion, and the influence on metastasis was verified <em>in vivo</em>. Flow cytometry was exploited to analyze the influence on the cell cycle and apoptosis. The regulatory mechanism of NKAPL was investigated by immunoprecipitation-mass spectrometry, western blotting, immunofluorescence, and immunohistochemistry. NKAPL was down-regulated due to promoter methylation, which was associated with poor prognosis in NSCLC patients, while the up-regulation of NKAPL suppressed NSCLC cell proliferation and metastasis both <em>in vitro</em> and <em>in vivo</em>. Mechanistically, the NF-κB signaling pathway was inhibited because the up-regulation of NKAPL increased the stability and expression of TRIM21.

Peripheral blood samples from fourteen JIA patients and four healthy individuals were subjected to single-cell RNA sequencing. Various subtypes of JIA were included in the patient cohort. Functional analyses, such as pseudotime trajectories and cell communication studies, were conducted to uncover immune cell changes in JIA patients. Results showed disrupted interferon and acute inflammatory responses in most cell types of JIA patients, with particularly intense responses in systemic JIA (sJIA) patients versus non-sJIA patients. Pseudotime analysis of CD4<sup>+</sup> T, CD8<sup>+</sup> T, B, and myeloid cells revealed that the functions of each cytokine production, cytotoxicity, and the processing and presentation of antigens were progressively strengthened, while the regulation of nuclear factor kappa B (NF-κB)-related pathways was weaker in CD4<sup>+</sup> T and CD8<sup>+</sup> T cells than in non-JIA. Reclustering analysis of myeloid cells highlighted interferon-related functions predominantly in non-classical monocytes of sJIA patients. Additionally, cell communication analysis identified unique ligand–receptor pairs in sJIA, suggesting potential roles in disease progression. In conclusion, interferon disorders are evident across various immune cell types in JIA patients, with stronger responses observed in sJIA patients. The ligand–receptor pairs involving migration inhibitory factor (MIF) and CXCR7/CD44 may contribute to differing joint symptoms between sJIA and non-sJIA patients. Moreover, non-classical monocytes and the CXCR2 receptor in MIF signaling may play crucial roles in sJIA progression.</div></div>","PeriodicalId":12689,"journal":{"name":"Genes & Diseases","volume":"12 5","pages":"Article 101577"},"PeriodicalIF":6.9,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144321991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
