Transcript
Mitochondrial-derived peptide
Mitochondria do more than help supply cellular energy. Researchers also study short mitochondrial-derived peptides such as MOTS-c as possible signals between cellular processes. [1]
Human measurement | Mouse intervention
A 2021 paper measured MOTS-c in people around exercise. In separate experiments, the researchers gave MOTS-c to mice and assessed physical performance. [1]
Observation does not prove treatment benefit
That distinction is essential. Observing a molecule change during exercise does not show that taking it improves human endurance. Mouse running results cannot supply that missing human trial. [1]
Human efficacy and safety remain unestablished
FDA notes missing human exposure data for MOTS-c drug products. The research helps frame questions about metabolism and aging, while human benefits and safety remain unestablished. [2]
