MOTS-c is a mitochondrial-derived peptide (MDP)
consisting of 16 amino acids, encoded directly from mitochondrial DNA rather
than nuclear DNA, making it unique among signaling molecules. It acts as an
exercise mimetic, primarily activating the AMPK pathway to regulate energy
metabolism, enhance glucose uptake via GLUT4 translocation, promote fatty acid
oxidation, and improve mitochondrial biogenesis and function.
MOTS-c supports metabolic flexibility by improving
insulin sensitivity and glucose tolerance, particularly in states of metabolic
stress like aging or high-fat diets, as shown in animal models where it
reversed insulin resistance and prevented diet-induced obesity. It boosts
endurance—treated mice ran twice as long and farther—while aiding fat loss
without muscle catabolism and enhancing recovery through better ATP production
and stress resilience. Longevity effects include mimicking caloric restriction
via FoxO activation and mitophagy, countering age-related mitochondrial
decline.
