MOTS-c and Immobilisation-Induced Muscle Atrophy in Mice

Researchers investigated MOTS-c in a hindlimb-immobilisation mouse model, with emphasis on muscle mass, lipid infiltration and related cellular pathways.

Study design

The study combined immobilised mice with muscle-cell experiments and measured muscle morphology, lipid-related changes, functional markers and signalling associated with atrophy.

What the researchers reported

MOTS-c exposure was associated with reduced lipid accumulation and attenuation of several muscle-atrophy measurements in the experimental model.

What this result does not establish

Immobilisation in mice is a controlled model and does not capture all causes of human muscle loss. The study did not establish clinical recovery, dosing or safety in people.

This article summarizes one published study about MOTS-c. It does not establish clinical efficacy, general safety, regulatory approval or suitability for human use. Findings should be interpreted within the model, methods and limitations of the original paper.
