What is the Origin of Epigenetics Modulation?

The term 'epigenetics' was coined in the 1940s by Conrad Waddington, combining epi (above, in addition to) and genetics, referring to the causal interactions between genes and their products that bring the phenotype into being. Modern modulation strategies arose from the genomic revolution, recognizing the profound plasticity of the human genome in response to environment and lifestyle.

What is the Mechanism of Epigenetics Modulation?

Epigenetics modulation works by altering the accessibility of DNA to the transcriptional machinery. Specific nutrients or compounds can act as cofactors for enzymes, such as DNA methyltransferases or histone deacetylases, that chemically tag the DNA or associated histone proteins. These chemical tags change how tightly the chromatin is packaged, directly influencing the rate of protein synthesis and gene expression.

Epigenetics Modulation

Meaning

The clinical and lifestyle-based strategy of influencing gene expression without altering the underlying DNA sequence itself, primarily through modifications like DNA methylation and histone acetylation. Modulation aims to optimize the cellular response to environmental stimuli and mitigate age-related decline by precisely controlling the accessibility of genetic information. This is a key area in personalized longevity medicine, affecting healthspan profoundly.
