Mitochondrial protection mechanisms

This is a collective term for the diverse and intricate cellular machinery that safeguards mitochondria, especially focusing on mitochondrial DNA repair and quality control. Mitochondrial protection includes the repair of mitochondrial DNA (primarily via base excision repair), the removal of damaged mitochondria by mitophagy, and dynamic processes such as mitochondrial fission and fusion, all essential for cellular energy production and survival. Deficiency or failure in these processes contributes prominently to age-related diseases, neurodegeneration, cancer, and metabolic disorders. No single molecule represents this "target": rather, it is an ensemble of pathways and proteins dedicated to preserving mitochondrial function[1][2][3][5][7][9].

Enhancement of base excision repair (BER) to repair oxidative DNA damage. Promotion of mitophagy to clear damaged mitochondria. Inhibition of fission to stabilize mitochondrial networks. Antioxidant action to reduce ROS burden, thus lessening need for repair.
