Abstract Mitochondria, ubiquitous double-membrane-bound organelles, regulate energy production, support cellular activities, harbor metabolic pathways, and, paradoxically, mediate cell fate. Evidence has shown mitochondria as points of convergence for diverse death-inducing pathways that trigger the various mechanisms underlying apoptotic and nonapoptotic programmed death. Thus, dysfunctional eventually lead or contribute to age-related diseases, such neurodegenerative, cardiovascular diseases. mitochondrion-associated death-based treatments show great therapeutic potential, providing novel insights in clinical trials. This review discusses mitochondrial quality control networks with activity triggered by stimuli maintain homeostasis via mitohormesis, unfolded protein response, mitophagy. The also presents details on forms mitochondria-associated death, including apoptosis, necroptosis, ferroptosis, pyroptosis, parthanatos, paraptosis, highlights their involvement disease pathogenesis, collectively suggesting directions further research.
