What is MOTS-c?
MOTS-c is a 16-amino-acid peptide encoded within mitochondrial DNA. Research has focused on metabolic homeostasis, skeletal muscle, cellular stress and more recently innate immune signalling.
Proposed mechanism
MOTS-c can move from mitochondria toward the nucleus during metabolic stress and influence nuclear gene expression. Experimental work links it with AMPK-related metabolism, glucose handling, adaptive stress responses and immune signalling.
What has been published?
Most intervention evidence remains preclinical. Human studies have measured endogenous circulating MOTS-c, including responses to exercise and associations with metabolic phenotypes. Newer research also describes host-defense and immunomodulatory functions.
Current human evidence
Human evidence mainly shows that MOTS-c exists endogenously and changes with physiology. This is not the same as evidence that administered MOTS-c improves performance, obesity, diabetes or longevity.
Regulatory status
MOTS-c remains investigational and is not an FDA-approved drug treatment.
Possible areas of research interest
- Mitochondrial signalling
- Metabolic stress
- Skeletal-muscle biology
- Innate immunity
Important limitations
- Most treatment claims rely on preclinical studies
- Human intervention evidence is limited
- Optimal formulation and pharmacology are unresolved
- Longevity claims are unproven
