Long-term exercise down-regulates leptin receptor mRNA in the arcuate nucleus.

Abstract

The purpose of this study was to investigate the effects of exercise on blood leptin concentrations and expression of leptin receptor subtype-b (Ob-Rb) mRNA in the arcuate nucleus of hypothalamus (ARC). Male Wistar rats (26 weeks old) underwent regular wheel exercise for 12 weeks. The expression of Ob-Rb mRNA in the ARC decreased at the end of the study… (More)
