Disruption of neuromedin B receptor improves mitochondrial oxidative phosphorylation capacity in gastrocnemius muscle of female mice

Abstract

This study describes neuromedin B (NB) and NB receptor as new regulators of skeletal muscle mitochondrial function. The white skeletal muscle mitochondrial oxidative phosphorylation capacity was increased by NB receptor genetic disruption in female mice. These findings may contribute to the resistance to diet-induced obesity, previously found in these mice, which requires future studies. Thus, investigations are necessary to clarify if blockade of NB receptor may be an approach to develop drugs to combat obesity.
