MOTS-c is a short mitochondria-derived peptide (MDP) encoded by an open reading frame within the 12S rRNA region of mitochondrial DNA (mtDNA). Comprising 16 amino acids, MOTS-c is unique among bioactive peptides because it is expressed in mitochondria, yet functions nuclearly and systemically, influencing metabolic homeostasis, insulin sensitivity, and cellular stress response.
It is gaining significant attention in the fields of aging research, obesity, metabolic disorders, and exercise physiology, due to its regulatory role in glucose utilization, fat metabolism, and cell survival.
MOTS-c acts at the crossroads of mitochondrial signaling and nuclear gene expression:
AMPK Activation: MOTS-c activates AMP-activated protein kinase, a master regulator of cellular energy balance, enhancing fatty acid oxidation, glucose uptake, and mitochondrial biogenesis.
Nuclear Translocation: During stress, MOTS-c translocates to the nucleus, where it regulates expression of adaptive metabolic genes.
Insulin Sensitivity: Improves glucose metabolism and enhances insulin signaling by modulating downstream pathways like PI3K/AKT.
Anti-Inflammatory Effects: Reduces proinflammatory cytokine expression and oxidative stress markers in various disease models.
Preclinical and Clinical Studies:
Obesity and Fat Loss: MOTS-c increases energy expenditure and reduces fat accumulation in high-fat diet mice, making it a candidate for obesity treatment.
Insulin Resistance and Diabetes: Enhances glucose clearance and insulin sensitivity in insulin-resistant models and human cells.
Exercise Mimetic Properties: Improves muscle mitochondrial function and endurance capacity; considered a "mitochondrial exercise signal".
Longevity and Aging: Shown to extend lifespan in certain animal models and counteract age-related metabolic decline.
Cognitive Health: Emerging evidence suggests protective effects in models of neuroinflammation and age-related cognitive impairment.
