Melanin-concentrating hormone (MCH) is a circulating 19-amino acid residue cyclic neuropeptide present in hypothalamus. In mammals, MCH is a, encoded by the precursor pro-melanin concentrating hormone (PMCH). It was first discovered in fish and subsequently in mammalian (rat). MCH perikarya is confined largely to the lateral hypothalamus area (LHA) and the adjacent zon incerta with extensive neuronal projections throughout the brain. MCH is detected in basal ganglia, neocortex, cerebellum, thymus, brown adipose tissue, duodenum, and testis. The structure of MCH is highly conserved among species.
Immunogen
synthetic peptide corresponding to human melanin-concentrating hormone conjugated to KLH. The MCH sequence is identical in many species including rat, mouse, and pig.
Application
Anti-MCH antibody may be used at a working dilution of 1:30000 for RIA. For immunohistochemistry of mouse hypothalamus sections, a working antibody dilution of 1:200 may be used. The antibody has been used for immunoblotting in cytoplasmic extracts of T cells at a concentration of 5.7 μg/ml. The antibody is suitable for protein microarray.
Anti-MCH antibody produced in rabbit has been used in radioimmunoassay and immunohistochemistry.
Biochem/physiol Actions
MCH mRNA is overexpressed and up-regulated during fasting in the hypothalamus of ob/ob mice as well as rats. Injection of MCH into the lateral ventricles in rats promote increased food consumption. In addition, knockout mice lacking MCH gene are lean and hypophagic and show an increase in metabolic rate. In contrast, overexpression of MCH in transgenic mice leads to obesity and insulin resistance.
Physical form
Solution in phosphate buffered saline containing 15 mM sodium azide.

Melanin-concentrating hormone (MCH), the neuropeptide produced mainly in the hypothalamus, plays an operative role in regulating food intake and the sleep/wake cycle. Considering that these physiological functions pursue diurnal variations, we checked whether the total hypothalamic MCH level depends on

Melanin-concentrating hormone (MCH) is a hypothalamic neuropeptide with a well-characterised role in energy homeostasis and emergent roles in diverse physiologic functions such as arousal, mood and reproduction. Work to date has predominantly focused on its hypothalamic functions using animal models;
Melanin-concentrating hormone-producing neurons (MCH neurons), found mainly in the lateral hypothalamus and surrounding areas, play essential roles in various brain functions, including sleep and wakefulness, reward, metabolism, learning, and memory. These neurons coexpress several neurotransmitters and act as glutamatergic neurons.
