the broad goal of this research was to examine the nature of the melanocortin receptor 1 (mc1r) locus on the coat color phenotype of seven goat breeds with different color coat. blood samples were collected from five iranian indigenous (khalkhal, markhor, naeini, najdi and tali) and two exotic (cashmere and saanen) goat breeds. polymerase chain reaction restriction fragment length polymorphism ...
The neural pathways through which central serotonergic systems regulate food intake and body weight remain to be fully elucidated. We report that serotonin, via action at serotonin1B receptors (5-HT1BRs), modulates the endogenous release of both agonists and antagonists of the melanocortin receptors, which are a core component of the central circuitry controlling body weight homeostasis. We als...
Haploinsufficiency of the melanocortin-4 receptor, the most common monogenetic obesity syndrome in humans, is associated with a reduction in autonomic tone, bradycardia, and incidence of obesity-associated hypertension. Thus, it has been assumed that melanocortin obesity syndrome may be protective with respect to obesity-associated cardiovascular disease. We show here that absence of the melano...
The central melanocortin system is involved in the regulation of food intake and body weight. In this study, we investigated the effect of a 4-week intracerebroventricular infusion of the melanocortin receptor agonist MT-II and the selective melanocortin-4 receptor antagonist HS024 on food intake and body weight homeostasis. The MT-II-treated rats ate less and lost considerably more weight than...
Genetic, biochemical and pharmacological studies in humans and rodents have established that signalling through the G-protein-coupled melanocortin-4 receptor (MC4R) by pro-opiomelanocortin (POMC)-derived ligands plays a critical role in the central suppression of appetite. As a consequence, malfunction of this signalling system leads to the development of obesity. It has been shown previously t...
Nesfatin-1 is a recently discovered hypothalamic peptide that was shown to suppress food intake through a melanocortin-3/4 receptor-dependent mechanism. Since nesfatin-1 mRNA is detected in the paraventricular nucleus of the hypothalamus, and because many peptides that alter food intake also influence cardiovascular function, we tested the ability of centrally administered nesfatin-1 to affect ...
