Mixed human biomarker + preclinical evidence · MOTS-c

MOTS-c is an exercise-induced mitochondrial-encoded regulator of physical decline

Exercise increased endogenous MOTS-c in muscle and circulation in the human component.

Quick read
Mixed human biomarker + preclinical evidence

What this study tells us

The human component measured the body’s own MOTS-c response before and after exercise; separate preclinical experiments explored biology. No exogenous MOTS-c was administered to the human participants, so this is not a human treatment-efficacy study.

Who was studied?

Young male exercise participants in human component

How many?

n=10

What happened?

Exercise increased endogenous MOTS-c in muscle and circulation in the human component.

What stops us overclaiming?

Endogenous peptide response is not evidence that injected/supplemented MOTS-c is effective or safe in humans.
