Summary: The study found increased average methylation levels in mouse cSCC, especially in stem-cell like human cSCC. There were striking similarities in differentially methylated genes between mouse and human cSCC, with locus specific methylation changes occurring in potential regulatory regions. Dysregulation of DNA methylation, particularly in the Filip1l gene, appears to contribute to the silencing of tumor suppressor genes in both murine and human cSCC.

Summary: Research reveals that satellite cell-derived myonuclei have distinct epigenetic characteristics and contributions during muscle adaptation. By comparing myonucleus-specific methylation profiling, it is found that satellite cell-derived myonuclei may preferentially supply specific ribosomal proteins to growing myofibers and retain an epigenetic memory of prior stem cell identity.

Summary: The central objective of combining discovery science with biomedical applications is to benefit patients and reduce the global disease burden. The conversion of DNA methylation (DNAm) from a biological process to a diagnostic tool is a prime example of this transformation, which took nearly a century. In recent years, DNAm studies have been standardized in clinical applications more than ever before, offering great potential for diagnosing various diseases associated with epigenetic alterations. DNAm detection plays a role in noninvasive prenatal testing and indicates prenatal risk factors in very preterm infants. In the field of cancer, liquid biopsy-based DNAm profiling provides valuable epigenetic biomarkers for early-stage diagnosis.

Summary: Obesity is a common metabolic disease caused by the interplay of genetic and environmental factors. Insulin resistance and obesity are closely related, and DNA methylation modification is an important epigenetic regulation method associated with their emergence. Adipose tissue plays a role in obesity and insulin resistance and affects their development through its DNA methylation. Understanding the research on DNA methylation, insulin resistance, and obesity can help identify new targets for clinical prevention and treatment of obesity.

Summary: There is evidence suggesting that infection with SARS-CoV-2 can lead to long-term sequelae, including diabetes. This mini-review examines the evolving literature on new-onset diabetes after COVID-19 (NODAC). Current evidence suggests that COVID-19 increases the risk of developing diabetes, but the exact causality is uncertain due to study limitations and the evolving nature of the pandemic. COVID-19 may have direct and indirect effects on pancreatic beta-cell function and insulin sensitivity.

Summary: This study aimed to assess risk factors for specific causes of graft loss after kidney transplantation. The results identified two distinct high-risk populations: a younger group with graft failure (GF) due to alloimmunity, and an older, commonly diabetic group with death with a functioning graft (DWFG) and GF due to a mixture of causes, many of which were nonalloimmune. Individualized management is needed to improve long-term renal allograft survival in the latter group.

Summary: In this study, we developed a novel computational immunology analysis pipeline called FastMix, which integrates flow cytometry, bulk transcriptomics, and clinical covariates to identify cell type-specific gene expression signatures and biomarker genes. FastMix addresses the challenges of integrating gene expression and flow cytometry analysis through a linear mixed effects model (LMER) and a moment-based estimator, which reduces bias in parameter estimation and improves efficiency. The FastMix pipeline also includes an advanced flow cytometry data analysis method called DAFi for identifying cell populations of interest and their characteristics. Simulation studies and validation using real data showed that FastMix outperformed competing methods in terms of smaller type I/II errors and producing additional interesting findings.

Summary: Obstructive sleep apnea (OSA) is a common sleep disorder and a known risk factor for cardiovascular diseases, including hypertension. The mechanisms involved in OSA-induced hypertension are multifactorial, and the gut microbiome is gaining attention as a potential factor. Perturbations in the gut microbiota have been linked to various disorders, and evidence suggests that gut dysbiosis may promote hypertension development in OSA. This review highlights the current research on the implications of altered gut microbiota for hypertension risk in OSA and potential therapeutic considerations.

Summary: Whole-genome methylation sequencing provides both DNA methylation and structural variant information. However, there is limited data on the reliability of obtaining this information simultaneously from low-input DNA using different library preparation and sequencing protocols. This study compared the performance of three protocols (EM-sequencing, QIA-sequencing, and Swift-sequencing) on CpG methylation measurement, SNV, and CNV detection. Results showed that at low DNA input, EM-sequencing was superior in most metrics except for CNV detection. EM-sequencing captured the highest number of CpGs and true SNVs, making it suitable for detecting methylation, SNVs, and CNVs from low-input DNA in a single sequencing.

Summary: Chronic sleep deficiency (CSD) poses a threat to physical health, mental well-being, and social functioning. Behaviorally induced CSD, now called insufficient sleep syndrome (ISS), is considered a form of central hypersomnolence disorder, with a global rise in voluntary sleep curtailment potentially making ISS the leading cause of CSD. However, ISS is not getting enough attention in contemporary medical practice and public health programs, and it is crucial to prioritize ISS as a public health issue in order to develop effective educational programs and regulations.
