This positions MOTS-c as both a metabolic regulator and a stress-responsive signaling molecule.

These findings were extended by subsequent studies showing that MOTS-c treatment increased physical performance in mouse models.

This variant has been associated with exceptional longevity in Japanese and Northeast Asian populations, suggesting that MOTS-c function may influence human lifespan 3 .

At the molecular level, MOTS-c activates the myogenic program and promotes satellite cell activation, suggesting direct effects on muscle regeneration and maintenance.

Evidence Gaps and Limitations # Several significant gaps exist in the current understanding of MOTS-c that must be addressed before clinical translation can proceed.

Because MOTS-c activates AMPK and promotes cell proliferation in certain contexts, potential oncogenic risks of chronic MOTS-c administration would need to be carefully evaluated before clinical development.

PMID: 33473109): Demonstrated that MOTS-c levels increase with exercise, decline with age, and that MOTS-c treatment in aged mice improves physical performance and skeletal muscle homeostasis.

Mitochondrial-derived peptide MOTS-c translocates to the nucleus in response to stress.

MOTS-c has attracted considerable research interest due to its role as a retrograde signaling molecule, communicating metabolic information from mitochondria back to the nucleus.

This mechanism provides a molecular explanation for the broad metabolic effects observed following MOTS-c administration in preclinical models and distinguishes MOTS-c from direct pharmacological AMPK activators such as metformin or AICAR itself, which act through different upstream mechanisms.
