Specific, modifiable molecular mechanisms that regulate gene expression without altering the underlying DNA sequence, which can be intentionally manipulated to influence healthspan and lifespan. These levers include DNA methylation, histone modification, and non-coding RNA expression, representing a crucial interface between lifestyle and genetic destiny. They offer tangible targets for optimizing the biological age of an individual.
Origin
The concept is a fusion of epigenetics and geroscience, focusing on the plasticity of the genome’s control mechanisms as a path to anti-aging and health optimization. Within clinical wellness, it provides a framework for understanding how diet, exercise, and hormonal balance can actively “reprogram” cellular function.
Mechanism
Activating these levers involves influencing the enzymes that add or remove chemical tags to DNA or histone proteins, effectively switching genes “on” or “off.” For instance, caloric restriction or specific nutritional compounds can modulate sirtuin activity, which acts as a sensor of cellular energy status and influences DNA repair and stability. By optimizing the hormonal environment, we can support the cellular machinery responsible for maintaining a youthful, functional epigenetic landscape.
