Epigenetics
Definition
Epigenetics refers to heritable changes in gene expression that occur without alterations to the DNA sequence itself, mediated by mechanisms including DNA methylation, histone modification, and non-coding RNA regulation. Age-related epigenetic changes are a hallmark of biological aging. Epithalon has been studied for its effects on telomerase activation which intersects with epigenetic regulation, and GHK-Cu has been shown to modulate the expression of thousands of genes, suggesting broad epigenetic influence.
