Growth hormone secretagogue receptor Growth hormone secretagogue receptor Growth hormone secretagogue receptor(GHS-R), also known as ghrelin receptor, is a G protein-coupled receptor that binds growth hormone secretagogues (GHSs), such as ghrelin, the "hunger hormone". The role of GHS-R is thought to be in regulating energy homeostasis and body weight. In the brain, they are most highly expressed in the hypothalamus, specifically the ventromedial nucleus and arcuate nucleus. GSH-Rs are also expressed in other areas of the brain, including the ventral tegmental area, hippocampus, and substantia nigra. Outside the central nervous system, too, GSH-Rs are also found in the liver, in skeletal muscle, and even
Growth hormone therapy shortness with normal test results as a disease rather than the extreme end of the normal height range Recombinant growth hormone available in the U.S. (and their manufacturers) included "Nutropin" (Genentech), "Humatrope" (Eli Lilly and Company), "Genotropin" (Pfizer), "Norditropin" (Novo Nordisk), "Tev-Tropin" (Teva) and "Saizen" (Merck Serono). The products are nearly identical in composition, efficacy, and cost, varying primarily in the formulations and delivery devices. Growth hormone (GH l) is also called somatotropin (British: somatotrophin). The human form of growth hormone is known as human growth hormone, or hGH (ovine growth hormone, or sheep growth hormone, is abbreviated oGH). GH
