Researchers at Weill Cornell Medicine, in collaboration with TruDiagnostic, have identified DNA markers linked to retroelements—ancient viral genetic remnants in our genes—that may serve as precise predictors of biological aging. The study, published in Aging Cell, reveals that these “Retro-Age” clocks capture aging signals not detected by other methods.
Using epigenetic data from over 12,000 individuals, the study found that methylation patterns on retroelements change with age, potentially leading to genomic instability and age-related diseases. The findings suggest retroelement activity is a key aspect of aging across species.
The research opens avenues for developing anti-aging therapies by targeting these specific DNA markers, offering hope for improving health span and lifespan.
