WebDr. Steve Horvath's epigenetic clock, the gold standard of aging clocks, predicts biological age by measuring DNA methylation at multiple sites [1, 2]. Accelerated epigenetic age has been associated with a lot of age-related conditions and diseases by independent research studies such as certain types of cancer [3, 4], obesity [5] and frailty [6]. WebNov 25, 2024 · The Horvath clock was constructed across multiple tissues, including the blood data from Hannum et al., as a potential “pan-tissue” master clock of chronological age, and focused on capturing shared changes, independent of tissue type [ 24 ].
