MOTS-c

🔬What Is MOTS-c

MOTS-c (Mitochondrial Open Reading Frame of the Twelve S rRNA type-c) is a mitochondrial-derived peptide consisting of 16 amino acids, encoded in the mitochondrial genome. Discovered in 2015 by Dr. Changhan David Lee at the University of Southern California, MOTS-c is one of the first identified mitochondrial-encoded signaling peptides that acts as a retrograde signal from mitochondria to the nucleus. Its primary mechanism involves activation of the AMPK (AMP-activated protein kinase) pathway and regulation of the folate-methionine cycle, which controls cellular metabolism. Published in Cell Metabolism, MOTS-c has been called an “exercise mimetic” because it activates many of the same metabolic pathways as physical exercise, including improved glucose uptake, fat oxidation, and mitochondrial biogenesis.

📊Clinical Studies & Results

MOTS-c is a mitochondrial-derived peptide (MDP) encoded within the 12S rRNA gene of mitochondrial DNA, functioning as a key metabolic regulator:

• ▪Identified as an exercise-induced mitochondrial-encoded regulator of age-dependent physical decline and muscle homeostasis (Reynolds et al., Nat Commun, 2021; PMID: 33446655)
• ▪Improved insulin sensitivity and glucose regulation in diet-induced obesity and aging models through AMPK pathway activation
• ▪Enhanced physical performance and endurance capacity in aged mice, reversing age-related decline in running endurance and grip strength
• ▪Translocated to the nucleus under metabolic stress to regulate adaptive nuclear gene expression, including genes related to the antioxidant response element (ARE) pathway
• ▪Endogenous MOTS-c levels decline with age and are inversely correlated with markers of metabolic dysfunction in human cohorts
• ▪Demonstrated anti-inflammatory effects by suppressing IL-6 and TNF-α in metabolically stressed conditions while preserving beneficial immune signaling

MOTS-c is a unique mitochondrial signaling peptide that bridges mitochondrial function, exercise physiology, and aging — positioning it as one of the most promising targets in longevity and metabolic health research.
