What is the Origin of Epigenetic Clocks?

The concept is a convergence of epigenetics, the study of heritable changes in gene function that occur without a change in the DNA sequence, and chronometry, the science of time measurement. The term gained prominence with the development of specific computational models that identified age-related methylation sites, effectively creating a molecular timepiece. This represents a significant advancement in geroscience.

What is the Mechanism of Epigenetic Clocks?

The mechanism relies on the consistent, age-dependent changes in DNA methylation, a process where a methyl group is added to the cytosine base of DNA. Specific CpG sites throughout the genome are either hyper- or hypo-methylated over time. The epigenetic clock algorithm aggregates the methylation status of hundreds of these sites to generate a single biological age estimate. This biological age is believed to reflect the integrity of cellular maintenance and repair pathways, offering a window into systemic health.

Epigenetic Clocks

Meaning

A set of mathematical algorithms that estimate an individual’s biological age, or “epigenetic age,” by analyzing patterns of DNA methylation across specific genomic sites. These clocks, such as the Horvath and Hannum clocks, provide a more dynamic and accurate measure of aging compared to chronological age, reflecting the cumulative impact of environmental and lifestyle factors on the genome. The acceleration or deceleration of the epigenetic clock serves as a critical biomarker for longevity science and personalized health interventions. This measurement offers tangible insight into the rate of biological decline.

Can Lifestyle Interventions Reverse My Biological Age as Measured by Epigenetic Clocks?

Lifestyle interventions can recalibrate the epigenetic clocks that measure biological age by optimizing DNA methylation patterns.
