MOTS-c
Also known as: Mitochondrial Open reading frame of the Twelve S rRNA type-c
MOTS-c is an investigational mitochondrial-derived peptide studied preclinically for metabolic regulation. It is research-only and not FDA-approved; the CB4211 analog program (CohBar) was discontinued in 2023.

Prices observed from public storefronts (last 24h), normalized to $/mg. "Evidence" is Merit's 0–100 Merit Score, derived only from observable verification evidence (methodology on /about); "Purity" is the latest independent COA. Some buy links are affiliate links — Merit may earn a commission at no extra cost to you, and where a vendor offers one, the code shown gets you a discount at their checkout. Affiliate status never affects price data, ranking, or the Merit Score (full policy on /disclosure). Research use only.

MOTS-c in sepsis-induced cardiomyopathy: Mechanisms and translational potential
Sepsis-induced cardiomyopathy (SICM) is a prevalent cardiac complication of sepsis that is characterized by inflammatory dysregulation, mitochondrial dysfunction, metabolic disturbance, and changes in the myocardial microenvironment.

MOTS-c is a mitochondrial-encoded interferon-linked host defense peptide
The mitochondrial DNA (mtDNA) can trigger immune responses and directly entrap pathogens, but it is not known to encode active immune factors. The immune system is traditionally thought to be exclusively nuclear-encoded.

Are serum MOTS-c levels and MOTS-c m.1382A>C polymorphism related to polycystic ovary syndrome?
Objective MOTS-c is a mitochondria-derived peptide associated with reduced insulin resistance and obesity. The m.1382A>C polymorphism of the MOTS-c gene is linked to an increased risk of type 2 diabetes in men.

MOTS-c partially protects against skeletal muscle deterioration in C26 cachexia
Background Cancer cachexia is a multifactorial metabolic syndrome marked by progressive skeletal muscle loss, reduced function, and increased mortality. Mitochondrial dysfunction is a key driver of this phenotype.

Humanin and MOTS-c Attenuate Atrial Fibrillation by Suppressing Fibrosis and Mitochondrial Dysfunction
Background: Atrial fibrillation (AF) is a common clinical arrhythmia associated with mitochondrial dysfunction, oxidative stress, and atrial fibrosis. Mitochondrial-derived peptides (MDPs), including humanin (HN) and MOTS-c, exhibit cytoprotective properties, but their role in AF remains largely unknown.
