MOTS-c

Also known as: Mitochondrial open reading frame of the 12S rRNA-c

A 16-amino-acid peptide encoded in the body's mitochondrial DNA, studied mainly in mice for effects on metabolism and insulin sensitivity.

Overview

MOTS-c is one of a small group of peptides encoded in mitochondrial DNA, the genetic material found in the cell's energy-producing structures, rather than in the cell nucleus. Its discovery shifted how researchers think about mitochondria as signaling organs.

What the research has looked at

In mice, MOTS-c treatment was reported to improve insulin sensitivity and to protect against weight gain on a high-fat diet. Other studies have examined its levels in humans, including changes with exercise and age.

What we do not know

  • Most findings come from mice, and effects in people have not been shown in controlled trials.
  • The exact mechanisms are still being worked out.
  • The safety and effects of long-term use in humans are unknown.

Regulatory context

MOTS-c is not an approved medicine.
