MOTS-c
A mitochondrial-derived peptide studied as an exercise mimetic in obesity and weight-management, insulin-sensitivity, and aging research.
MOTS-c is a 16-amino-acid mitochondrial-derived peptide encoded by the mitochondrial 12S rRNA gene. Discovered in 2015, it has become a focus of metabolic and longevity research, where it is described as an “exercise mimetic” because its expression rises in response to exercise and metabolic stress.
Research examines MOTS-c’s role in glucose metabolism, insulin sensitivity, and the cellular stress response via the AMPK pathway. The evidence is primarily preclinical. Note that MOTS-c was added to the World Anti-Doping Agency prohibited list, which is relevant context for sports-research settings.
Research areas
Metabolic Regulation
Studied for effects on glucose handling and insulin sensitivity in skeletal-muscle models.
Exercise Mimetic
Expression increases with exercise; research explores whether it reproduces some exercise-associated metabolic adaptations.
AMPK Pathway
Acts through the folate–AICAR–AMPK pathway to influence energy metabolism, a key research mechanism.
Aging & Stress Response
Investigated for roles in cellular stress adaptation and age-related metabolic decline.
