The m6A methyltransferase METTL3 regulates muscle maintenance and growth in mice

Abstract

Muscle undergoes hypertrophy and atrophy in response to physiological stimuli or in pathological conditions, which is partially controlled through altered gene expression. Here the authors report that m6A methyltransferase METTL3 and mRNA m6A post-transcriptional modifications as a mechanism that regulates muscle hypertrophy and atrophy via myostatin signalling in mice.
