Description

MOTS-c is a small bioactive peptide derived from mitochondrial DNA that has gathered attention for its unique role in cellular metabolism and stress adaptation. Composed of 16 amino acids, MOTS-c functions as a mitochondrial-derived signaling molecule, influencing nuclear gene expression and coordinating metabolic homeostasis. It is known to activate pathways such as AMP-activated protein kinase, thereby enhancing glucose utilization, promoting fatty acid oxidation, and increasing cellular resistance to oxidative stress. Beyond its metabolic effects, MOTS-c has been studied for its protective roles in age-related disorders, cardiovascular disease, and inflammatory conditions due to its ability to modulate antioxidant responses and reduce cellular apoptosis. Because it is endogenously produced and acts as a regulator of systemic energy balance, MOTS-c has become an important focus of research in understanding how mitochondrial signaling contributes to overall health, disease prevention, and potential therapeutic interventions.
