MOTS-c and exercise: two different kinds of evidence

A publication combined experiments on physical performance in mice with observations of endogenous MOTS-c in human muscle and circulation around exercise.

What the research examined

A publication combined experiments on physical performance in mice with observations of endogenous MOTS-c in human muscle and circulation around exercise. The human and animal parts of the paper ask different questions.

How to interpret the findings

An exercise-associated change in a naturally occurring human peptide is not a trial of giving that peptide to people. The mouse intervention cannot fill that gap, and the two findings should not be presented as a demonstrated human performance effect.

Research literature

  1. MOTS-c is an exercise-induced mitochondrial-encoded regulator of age-dependent physical decline and muscle homeostasis.
