Melanocortin-4 receptor (MC4R) is associated with feed intake, growth, fatness, and carcass composition in many domestic animals. The aim of this study was to evaluate the association of single nucleotide polymorphisms (SNPs) in MC4R with milk production traits in water buffalo. Eight SNPs were identified by direct polymerase chain reaction sequencing of samples from 18 buffaloes. SNPs were the...
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 melanocortin system is a critical component of the forebrain and hindbrain regulatory systems involved in energy balance. This system is composed of pro-opiomelanocortin (POMC) neurons that act, in part, through the melanocortin-4 receptor (MC4R). Although the importance of the melanocortin system in controlling feeding has been established for two decades, the understanding of the developm...
Background and purpose: This study aimed at examining the interaction between macronutrients, some micronutrients (magnesium, zinc, iron, calcium, and copper) and CCND2 rs11063069, ZNT8 rs13266634, and MC4R rs12970134 polymorphisms in relation to metabolic syndrome (MetS) and its components. Materials and methods: In this matched nested case-control study, the data for 1634 (817 pairs) case (t...
تحقیق حاضر جهت بررسی چندشکلی ژنهای گیرنده لپتین (LEPR) و گیرنده ملانوکورتین 4 (MC4R) در گاوهای بومی استان گیلان انجام شد. بدین منظور از 96 رأس گاو بومی استان گیلان به طور تصادفی خونگیری به عمل آمد. پس از استخراج DNA با استفاده از روش نمکی بهینه یافته، واکنش زنجیره ای پلیمراز (PCR) برای تکثیر قطعه 269 جفت بازی اگزون 2 ژن LEPR و قطعه 213 جفت بازی از اگزون 1 ژن MC4R انجام شد. چندشکلی فضایی تکرش...
UNLABELLED Osteoporosis is characterized by reduced bone mineral density (BMD) and increased fracture risk. Fat mass is a determinant of bone strength and both phenotypes have a strong genetic component. In this study, we examined the association between obesity associated polymorphisms (SNPs) with body composition, BMD, Ultrasound (QUS), fracture and biomarkers (Homocysteine (Hcy), folate, Vit...
Melanocortin receptor accessory proteins (MRAPs) are regulators of the melanocortin receptor family. MRAP is an essential accessory factor for the functional expression of the MC2R/ACTH receptor. The importance of MRAP in adrenal gland physiology is demonstrated by the clinical condition familial glucocorticoid deficiency type 2. The role of its paralog melanocortin-2-receptor accessory protein...
The discovery of leptin substantiated the usefulness of a forward genetic approach in elucidating the molecular network regulating energy metabolism. However, no successful dominant screening for obesity has been reported, which may be due to the influence of quantitative trait loci between the screening and counter strains and the low fertility of obese mice. Here, we performed a dominant scre...

BACKGROUND Recent studies indicated that eating behaviors are under genetic influence, and the melanocortin 4 receptor (MC4R) gene polymorphisms can affect the total energy intake and the consumption of fat, protein and carbohydrates. Our study aims at investigating the association of the MC4R polymorphism with appetite and food intake among Chinese children. METHODS A family-based associatio...
