What is the Origin of Endogenous Repair Capacity?

The concept is rooted in molecular biology and gerontology, focusing on the cellular and biochemical pathways that maintain genomic and proteomic integrity. The term 'endogenous' highlights that this capacity is internally driven and sustained by the organism's own biological machinery.

What is the Mechanism of Endogenous Repair Capacity?

Key mechanisms include the activation of stress response pathways, such as the sirtuin and AMPK pathways, which are highly sensitive to nutrient and energy status. These pathways promote the clearance of dysfunctional mitochondria (mitophagy) and initiate the transcription of genes responsible for antioxidant defense and DNA repair enzymes. Hormonal balance, particularly the signaling from growth factors and sex steroids, is instrumental in providing the necessary anabolic signals to execute these complex repair programs efficiently.

Endogenous Repair Capacity

Meaning

Endogenous repair capacity refers to the intrinsic, genetically encoded ability of the body’s cells and tissues to detect, mitigate, and reverse damage caused by metabolic stress, oxidative species, and accumulated molecular lesions. This foundational biological capability encompasses processes like DNA repair, protein quality control, and cellular autophagy. Supporting this capacity is central to clinical longevity strategies, as it dictates the rate of physiological aging and resilience.
