Mitochondrial oxidative damage

Mitochondrial oxidative damage is not a discrete molecule or receptor, but refers to the cellular injury resulting from excess ROS generated by the mitochondrial electron transport chain, particularly at complexes I and III, overwhelming native antioxidant defenses. This process causes modification and degradation of mitochondrial DNA, proteins, and lipids, leading to loss of mitochondrial function, impairment of ATP production, activation of cell death pathways, and is implicated as a central driver in aging, neurodegenerative conditions, cardiovascular disorders, cancer, and other pathologies. Therapeutic strategies often aim at scavenging mitochondrial ROS or boosting mitochondrial antioxidant defenses, though clinical efficacy remains limited due to biological complexity.
