Abstract
Pro-opiomelanocortin (POMC) expressing neurons mediate the regulation of orexigenic drive by peripheral hormones such as leptin, cholecystokinin, ghrelin, and insulin. Most research effort has focused on α-melanocyte-stimulating hormone (α-MSH) as the predominant POMC-derived neuropeptide in the central regulation of human energy balance and body weight. Here we report a missense mutation within the coding region of the POMC-derived peptide β-MSH (Y5C-β-MSH) and its association with early-onset human obesity. In vitro and in vivo data as well as postmortem human brain studies indicate that the POMC-derived neuropeptide β-MSH plays a critical role in the hypothalamic control of body weight in humans. © 2006 Elsevier Inc.
