another name for growth hormone is
Growth hormone (GH or HGH), also known as somatotropin or somatropin, is a peptide hormone that stimulates growth, cell reproduction and regeneration in humans and other animals. It is a type of mitogen which is specific only to certain kinds of cells. Advertisement History Growth hormone is a protein produced by the pituitary gland, a small peanut-shaped master gland located at the base of the brain. The pituitary gland not only controls physical growth, but also regulates other glands throughout the body that produce hormones such as testosterone and estrogen. What are the functions of PTH (parathyroid hormone-parathormone). regulates calcium & phosphorus blood levels; promotes bone demineralization & increases intestinal absorption of Ca2+; increases serum Ca2+ levels. The insertion of genes into cells is known as recombinant gene technology. The first version of recombinant human growth hormone (sometimes called rhGH) was made by Genentech of South San Francisco, California, and approved for sale by the U.S. Food and Drug Administration (FDA) in October 1985. Growth hormone is a 191- amino acid, single-chain polypeptide that is synthesized, stored, and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland. GH is a stress hormone that raises the concentration of glucose and free fatty acids. It also stimulates production of IGF-1. HGH, also known as somatropin, was first used to treat stunted growth in children. Later it was used in people with HIV disease to treat the gauntness of AIDS-related wasting and, more recently, the fat accumulations associated with lipodystrophy. HGH also may play a role in immune reconstitution. Main articles: Growth hormone 1 and Growth hormone 2. Genes for human growth hormone, known as growth hormone 1 (somatotropin) and growth hormone 2, are localized in the q22-24 region of chromosome 17 and are closely related to human chorionic somatomammotropin (also known as placental lactogen) genes. In recent years in the United States, some doctors have started to prescribe growth hormone in GH-deficient older patients (but not on healthy people) to increase vitality. While legal, the efficacy and safety of this use for HGH has not been tested in a clinical trial. Studies of growth hormone have not been conducted in pregnant women. Up to 50% of all people experience mild to moderate musculoskeletal discomfort when starting hGH, and about 25% experience some fluid retention and swelling of the hands and feet. Growth hormone can be very beneficial for correcting a deficiency, but having too much of it does not necessarily bring added benefit -- though it does increase the risk of side effects. Nevertheless, illicit use of hGH appears to be widespread.
