Epigenetic clocks, particularly those tuned to phenotypic age or mortality risk (e.g., GrimAge), are robust biomarkers for predicting biological aging and adverse health outcomes.
Epigenetic clocks offer a promising way to measure biological age, potentially identifying those aging faster than their chronological age. This could guide personalized interventions to slow aging, though clinical application is still emerging.

A recent literature suggests that hydroxymethylcytosine (5hmC)... is a novel DNA epigenetic modulator... Overall, DNA methylation is emerging as one of the most robust biomarkers of 'biological aging'...
Why this rating
Strong observational evidence across multiple populations and tissues.

More from this paper
- Biological aging is driven by the interaction between accumulated cellular damage and the decline of homeostatic resilience mechanisms, rather than chronological time alone.Good
- Cellular senescence and the accumulation of senescent cells contribute to tissue degeneration and age-related diseases, making their removal or suppression a potential therapeutic target.Good
