Abstract Parkinson’s Disease (PD) is a progressive neurodegenerative disorder with no cure. Clinical presentation characterized by postural instability, resting tremors, and gait problems that result from loss of A9 dopaminergic neurons in the substantia nigra pars compacta.

Therefore, it is important increase our understanding biology cells utilize this information enhance their function in heart. Mitochondria are critical for progenitor cell survival. Here, we demonstrate importance mitochondrial autophagy, or mitophagy, differentiation process adult cardiac (CPCs). We found that mitophagy was rapidly induced upon initiation CPCs. also mediated by receptors, rather than PINK1-PRKN/PARKIN pathway. Mitophagy BNIP3L/NIX FUNDC1 not involved regulating fate determination, biogenesis, reprogramming. Instead, facilitated CPCs undergo proper network reorganization during differentiation.

Biological energy transduction underlies all physiological phenomena in cells. The metabolic systems that support have been of great interest due to their association with numerous pathologies including diabetes, cancer, rare genetic diseases, and aberrant cell death.
