Researchers report that measuring chromatin accessibility—which regions of DNA are open and available for activity—can reveal disease-associated genetic signals that standard gene expression analysis fails to capture. The findings come from a study published via Nature's research platform, though specific methods and disease models were not detailed in the available text.
A research consortium has published a large-scale multiome dataset profiling gene expression and chromatin accessibility across immune cell types in many individuals, generating single-cell eQTLs and chromatin accessibility QTLs. The dataset is designed to help pinpoint which genetic variants associated with disease actually alter gene regulation in specific immune cell states, building on prior efforts like GTEx, ENCODE and FinnGen.
A newly published review compiles evidence that cells across the body gradually lose their defined molecular identity as organisms age, with this drift appearing alongside known age-related functional decline in tissues. The paper draws on decades of research spanning cellular turnover rates, epigenetic memory maintenance, chromatin organization and stress-response pathways to build its case.
