The Takeaway
This is the first human proof-of-concept for 'gerotherapeutics,' showing that existing antiviral medication can reverse epigenetic aging clocks. The drug works by suppressing ancient 'jumping genes' (retrotransposons) in our DNA that are normally kept silent but become active and cause inflammation as we age.
From the abstract
Nucleos(t)ide reverse transcriptase inhibitors (NRTIs) used for HIV treatment and pre-exposure prophylaxis have been proposed as gerotherapeutics based on their capacity to suppress age-associated retrotransposon activity. However, evidence in humans is currently lacking. Here we evaluated DNA methylation-based measures of biological aging in healthy people without HIV (aged 18-50) using samples from two separate randomized, directly observed dosing pharmacokinetic studies of FDA-approved NRTI r
