Background: Cocaine- and amphetamine-regulated transcript (CART) peptides are neurotransmitters of 39 and 47 amino acids that are involved in a variety of physiological processes. The CART precursor, a polypeptide of 116 residues, requires prohormone/proprotein convertase-mediated endoproteolytic cleavage to produce the two active peptides (1). CART peptides are found in several neuroendocrine tissues such as the brain, pituitary, adrenals, and pancreas (2). Hypothalamic CART is regulated by leptin, and plays a role in appetite and feeding behavior (3). Mesolimbic CART is regulated by CREB and may play a role in drug abuse behaviors by mediating some of CREB effects (4). Pancreatic CART is found in islet endocrine cells and parasympathetic and sensory nerves. It inhibits glucose-stimulated insulin secretion and has been found to be up-regulated in beta cells in animal model of diabetes (5). A missense mutation in the corresponding CART gene can correlate with susceptibility to obesity and reduced resting energy expenditure (6).

Background: Pro-Opio-Melano-Cortin (POMC) is a precursor protein expressed in the pituitary and the brain where it is processed into several peptide hormones and neuropeptides. Among these peptides are ACTH, α- and β-MSH, β-and γ-LPH, CLIP, β-endorphin, and N-POMC (1). POMC is involved in hypothalamic circuits regulating feeding behavior and POMC-producing neurons promote satiety (2). POMC neurons are also the target of leptin and insulin for the promotion of the browning of white fat (3).
