What is the Origin of Epigenetic Drift Mitigation?

Rooted deeply in epigenetics, the study of heritable changes in phenotype without altering genotype, the term "drift" describes the accumulation of undesirable expression changes over the lifespan. Mitigation strategies are informed by research identifying environmental and lifestyle factors that drive these molecular shifts.

What is the Mechanism of Epigenetic Drift Mitigation?

Mitigation strategies typically target metabolic pathways that influence the availability of epigenetic modifying enzymes and their substrates, such as S-adenosylmethionine (SAM). By optimizing nutrient status and reducing chronic systemic stressors, we can influence the activity of DNA methyltransferases or histone deacetylases, thereby stabilizing the genome's regulatory landscape.

Epigenetic Drift Mitigation

Meaning

Interventions aimed at slowing or reversing the progressive, age-related changes in gene expression patterns—specifically DNA methylation and histone modification—that occur independent of underlying DNA sequence alterations. Mitigation seeks to preserve the youthful or desired gene expression profile critical for optimal endocrine function and tissue health. This addresses how lifestyle influences genetic expression over time.
