Dynamic DNA Methylation during aging

“When UCLA scientist Steve Horvath unveiled his so-called Horvath clock, it was a step in this direction. It’s a tool to measure biological aging based on epigenetics, the shifting patterns of methylation and other types of DNA modification that change as we age. The concept of his clock is that as we age, DNA methylation patterns shift. These epigenetic patterns correlate with aging, serving as a kind of biomarker for estimating biological age, a better measure of how quickly we’re aging than chronological age.”    MORE
