Brainstem Melanocortin 3/4 Receptor Stimulation Increases Uncoupling Protein Gene Expression in Brown Fat

Abstract excerpt

Central administration of melanocortin 3 and 4 receptor (MC3/4-R) agonists increases energy expenditure, with the hypothalamus commonly held as the primary site of action. It is also clear, however, that MC4-R are expressed in caudal brainstem structures of relevance to the control of energy expenditure. Three experiments investigated whether hindbrain MC-R contribute to the energy expenditure effects of central...
