AI Summary
MOTS-c is a mitochondrial-derived peptide (MDP) of 16 amino acids, encoded within the mitochondrial 12S rRNA region. The evidence base is preclinical: landmark cell and animal studies describe effects on metabolic homeostasis, insulin sensitivity, and nuclear gene regulation under metabolic stress, and later studies explored metabolic disease models. Independent controlled human outcome trials are lacking, and it is not approved by any regulator. Effects are framed as studied in laboratory and animal models, not established in humans.
Key Information
Classification
Key Takeaways
- MOTS-c is a mitochondrial-derived 16-amino-acid peptide studied for metabolic effects
- Evidence is from laboratory and animal models (metabolism, insulin sensitivity)
- It is not approved by any regulator, and human treatment data are lacking
Scientific Overview
In Plain English
MOTS-c is a small peptide made from mitochondrial DNA. Laboratory and animal studies suggest it can influence metabolism and how the body responds to insulin, and it can move into the cell nucleus to affect gene activity under stress. It is a research target, not an approved medicine, and there are no controlled human treatment trials establishing benefit.
Scientific Details
MOTS-c is a 16-amino-acid mitochondrial-derived peptide. A landmark 2015 study described effects on metabolic homeostasis, obesity, and insulin resistance in animal models, and a 2018 study reported nuclear translocation of MOTS-c to regulate nuclear gene expression in response to metabolic stress. Subsequent work examined metabolic-disease models. The literature is predominantly preclinical, and controlled human outcome data are not available.
How It Works
MOTS-c is described in research as a mitochondrial-derived peptide associated with activation of metabolic stress pathways (including AMPK-related signaling) and, under stress, translocation to the nucleus to influence gene expression, in cell and animal models. These mechanisms are characterized preclinically and are not confirmed by controlled human studies.
Mechanism of Action
Metabolic-stress signaling
animal
Cell and animal studies associate MOTS-c with activation of AMPK-related metabolic pathways and improved insulin sensitivity in models.
Nuclear gene regulation
cell
Under metabolic stress, MOTS-c has been reported to translocate to the nucleus and influence nuclear gene expression.
Evidence Level
Human Evidence
Independent controlled human outcome trials are not available; MOTS-c is studied as a research target rather than an established therapy.
Animal Evidence
Rodent studies describe effects on metabolism, obesity, and insulin resistance.
Cell Evidence
In vitro studies describe metabolic signaling and nuclear translocation under stress.
Limitations
The literature is predominantly preclinical; there are no controlled human efficacy or safety trials, and it is not an approved medicine.
Why This Grade
Graded preclinical: metabolic effects are described in cell and animal models only, without controlled human outcome data.
