Abstract
The melanocortin pathway consists of endogenous agonists, antagonists, G-protein coupled receptors, and ancillary proteins that mediate the function of the endogenous antagonists. The melanocortin-4 receptor (MC4R) is involved in the regulation of obesity and the melanocortin-2 receptor (MC2R) is involved in the regulation of steroidogenesis. Herein, we present the effects of voluntary exercise on the MC4R knockout mice in terms of bypassing the morbid obesity and hyperphagia phenotypes associated with this genetic obesity model. Additionally, a systematic truncation study of the adrenocorticotropin hormone (ACTH 1-24) has been performed and characterized at the cloned MC2R.
