Cellular Maintenance Program

Meaning

The Cellular Maintenance Program refers to the collective, highly regulated intrinsic biological processes within a cell dedicated to preserving its structural integrity, functional capacity, and genetic fidelity over time. These essential processes include mechanisms like DNA repair, protein quality control via the ubiquitin-proteasome system, and the removal of damaged organelles through autophagy. A robust maintenance program is fundamental to tissue health, mitigating cellular senescence and reducing the accumulation of molecular damage associated with aging and chronic disease.
