Cure8 research brief
This study suggests a new, compact DNA-methylation biomarker that identifies accelerated aging in the colon linked to chronic inflammation (IBD) and pre-cancerous conditions. Such biomarkers could eventually help researchers understand disease-related tissue changes and risk.
Researchers studying IBD, inflammation, or colorectal neoplasia; clinicians and translational scientists interested in biomarkers of tissue aging; adult patients following research on disease mechanisms and cancer risk.
Researchers developed colon-specific “epigenetic clocks” that predict tissue age from a small set of DNA methylation (CpG) sites. The models were trained on healthy colon samples and performed well with far fewer features and samples than traditional clocks.
When applied to disease tissue, the clocks showed patterns consistent with accelerated colon aging in inflammatory bowel disease (IBD), HIV infection, and colonic polyps; aspirin exposure was associated with partial slowing of the clock in the study cohort.
These colon-focused clocks are presented as an efficient, more interpretable biomarker approach that may help researchers study how chronic inflammation and neoplasia affect colon aging.
Structured content depth is an abstract from a Scientific Reports article. Findings are based on methylation patterns and model performance reported in the paper; this is a research study, not a clinical test or approved diagnostic. The abstract reports associations (accelerated aging signals) rather than clinical outcomes.
