A Cellular Maintenance Strategy is a clinical framework designed to proactively support the molecular processes that preserve cellular integrity, optimize function, and resist age-related degradation across all tissues. This strategy focuses on enhancing endogenous repair mechanisms, including DNA repair, protein quality control, and the clearance of damaged organelles and senescent cells. It represents a systematic approach to slowing the accumulation of cellular damage, which is a primary driver of biological aging.
Origin
This term is a practical application derived from the foundational research in molecular gerontology, particularly the delineation of the various hallmarks of aging at the cellular level. The need for a cohesive ‘strategy’ arose from the understanding that addressing single pathways is insufficient, necessitating a multi-faceted approach to cellular health. It integrates concepts from autophagy research, telomere biology, and epigenetics into a comprehensive clinical plan.
Mechanism
Key mechanisms include the induction of autophagy, a cellular self-cleaning process, often stimulated by nutrient sensing pathways like mTOR and AMPK, which are responsive to diet and exercise. Furthermore, the strategy supports the action of sirtuins, a class of enzymes that regulate DNA repair and gene expression in response to cellular stress. Hormones act as crucial systemic regulators, with growth hormone and thyroid hormones influencing protein synthesis and turnover, thus playing an integral part in the overall cellular maintenance and repair capacity.
