1. Frequências de genes candidatos e associações com características de carcaça e da carne em bovinos da raça Nelore e cruzados
Resumo: O objetivo deste trabalho foi estimar as frequências alélicas dos polimorfismos IGF2/MboII (G > T) do gene "insulin-like growth fator 2" (IGF2), DQ499531.1:g.134 A> T do gene "pro-melanin-concentrating hormone" (PMCH) e DQ667048.1:g.3290G> T do gene "RAR-related orphan receptor C" (RORC) em bovinos de corte de diferentes grupos genéticos, e avalia

2. Efeitos do treinamento físico intenso e da restrição alimentar sobre a ação da leptina mediada pelo hormônio concentrador de melanina no eixo reprodutor de ratas. / Effects of intense physical training and food restriction on the action of leptin mediated by melanin concentrating hormone in the reproductive axis in female rats.
Avaliamos o efeito do treinamento físico intenso e da restrição alimentar no eixo reprodutor e na expressão do RNAm do MCH em ratas fêmeas. Utilizamos ratas fêmeas sedentárias alimentadas (SA), sedentárias com restrição alimentar, treinadas alimentadas (TA) e treinadas com restrição alimentar. O grupo TR entrou em anestro a partir da quarta seman

3. Estudo das aferências imunorreativas ao hormônio concentrador de melanina (MCH) do núcleo accumbens, no rato Long-Evans (Rattus norvegicus). / Study of melanin-concentrating hormone (MCH) immunoreactive inputs of nucleus acumbens, in rats Long-Evans (Rattus norvegicus) .
O MCH é um neuropeptídeo sintetizado preferencialmente no hipotálamo que exibe projeções para todo o neuroeixo, podendo modular vários processos fisiológicos, como a ingestão aguda de alimento. Um alvo de suas projeções é o núcleo accumbens (Acb), componente do estriado ventral envolvido na recompensa de estímulos hedônicos. Nossa contribuiçã

4. Melanin-concentrating hormone and orexin A neuropeptidergic systems in the dorsal motor nucleus of the vagus nerve in rat / Sistema neuropeptidergico do hormonio concentrador de melanina e da orexina A no nucleo motor dorsal do nervo vago em rato
Melanin-concentrating hormone (MCH) and orexin-A (OXA) are neuromediators expressed in neurons distributed in the diencephalum, mainly in the lateral hypothalamic area, projecting nerve fibers to several parts of the central nervous system. These neuropeptides exert potent orexigenic activity, increasing feeding and controlling the energetic balance. Consequ

5. Busca alimentar, memória espacial e ansiedade em ratos: possível participação do núcleo mamilar medial / Search for food, spatial memory and anxiety in rats: possible participation of the medial mammillary nucleus
Seres humanos com danos nos corpos mamilares exibem prejuízos no funcionamento da memória episódica. O presente estudo investigou a possível participação do núcleo mamilar medial (MM), estrutura densamente inervada por fibras imunorreativas ao hormônio concentrador de melanina (MCH) potencialmente envolvida no comportamento alimentar, em processos de

8. Two precursors of melanin-concentrating hormone: DNA sequence analysis and in situ immunochemical localization.
Two precursors to Chinook salmon (Oncorhynchus tshawytscha) melanin-concentrating hormone, an important factor in teleosts involved in the control of skin pigmentation and stress responsiveness, have been identified from DNA sequence analysis. Both precursors encode proteins of 132 amino acids and they share 107/132 amino acid identities. The biologically ac

9. The melanin-concentrating hormone receptor 1, a novel target of autoantibody responses in vitiligo
Vitiligo is a common depigmenting disorder resulting from the loss of melanocytes in the skin. The pathogenesis of the disease remains obscure, although autoimmune mechanisms are thought to be involved. Indeed, autoantibodies and autoreactive T lymphocytes that target melanocytes have been reported in some vitiligo patients. The objective of this study was t

10. Identification and characterization of a melanin-concentrating hormone receptor
Melanin-concentrating hormone (MCH), a neuropeptide expressed in central and peripheral nervous systems, plays an important role in the control of feeding behaviors and energy metabolism. An orphan G protein-coupled receptor (SLC-1/GPR24) has recently been identified as a receptor for MCH (MCHR1). We report here the identification and characterization of a G

11. Melanin-concentrating hormone: unique peptide neuronal system in the rat brain and pituitary gland.
A unique neuronal system was detected in the rat central nervous system by immunohistochemistry and radioimmunoassay with antibodies to salmon melanin-concentrating hormone (MCH). MCH-like immunoreactive (MCH-LI) cell bodies were confined to the hypothalamus. MCH-LI fibers were found throughout the brain but were most prevalent in hypothalamus, mesencephalon

12. Melanin-concentrating hormone is a critical mediator of the leptin-deficient phenotype
Energy homeostasis is regulated by a complex network involving peripheral and central signals that determine food intake and energy expenditure. Melanin-concentrating hormone (MCH) plays an essential role in this process. Animals treated with MCH develop hyperphagia and obesity. Ablation of the prepro-MCH gene leads to a lean phenotype, as does ablation
