Sperm Mitochondrial DNA Copy Number and Nuclear DNA Methylation Across Clinical and Non‐Clinical Preconception Cohorts

Andrology, EarlyView.
ABSTRACT Background Sperm mitochondrial DNA copy number is an emerging marker of male fertility, with elevated mtDNAcn associated with poor semen quality across various populations. Sperm DNA methylation has also been previously demonstrated to be negatively correlated with semen parameters in IVF cohorts.

PFOS-mediated suppression of SOX30 impairs DNA double-strand break repair leading to male reproductive dysfunction

Ecotoxicology and Environmental Safety
Perfluorooctanesulfonic acid (PFOS), a persistent organic pollutant and representative per- and polyfluoroalkyl substance (PFAS), is ubiquitously detected in the environment and human tissues, and mounting evidence has implicated it in male reproductive ...

Mapping Meiotic Recombination DNA Double‐Strand Breaks (DSBs) Hotspots —Methodological Advances and Challenges

Advanced Genetics, Volume 7, Issue 3, September 2026.
ABSTRACT Programmed DNA double‐strand breaks (DSBs) initiate meiotic recombination at discrete genomic hotspots, and their precise mapping is crucial for understanding the molecular regulation of genome stability and evolution. A variety of genome‐wide methods have been developed, each leveraging different biochemical principles — from direct capture ...

Single‐cell marker gene clustering: A unified deep learning framework for marker gene‐based clustering of single‐cell RNA‐sequencing data

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract Single‐cell RNA sequencing (scRNA‐seq) has transformed the study of cellular heterogeneity by making it possible to classify individual cells and their functional states. However, the analysis remains difficult because high dropout rates lead to sparse and noisy expression data.
