What is the Origin of Epigenetic Clock Modification?

This term originates from the convergence of epigenetics—the study of heritable phenotype changes that do not involve alterations in the DNA sequence—and aging research. The 'clock' metaphor quantifies accumulated epigenetic drift over time. Modification implies an active, targeted influence on these chemical tags on DNA.

What is the Mechanism of Epigenetic Clock Modification?

The process involves influencing the enzymatic machinery responsible for DNA methylation and demethylation, such as DNA methyltransferases (DNMTs) and ten-eleven translocation (TET) enzymes. Factors like caloric restriction mimetics or specific nutrient cofactors can alter the availability of S-adenosylmethionine (SAMe), a key methyl donor. By modulating these epigenetic regulators, we aim to reset cellular transcriptional profiles toward a younger, more robust state.

Epigenetic Clock Modification

Meaning

Epigenetic Clock Modification refers to the intentional alteration of biological aging markers, as quantified by specific DNA methylation patterns (e.g., Horvath’s clock), through lifestyle, nutritional, or targeted molecular interventions. The objective is to slow down, halt, or potentially reverse the calculated epigenetic age relative to chronological age. This represents a frontier in understanding biological resilience.
