Growth Hormone

22 kDa pituitary somatotroph hormone regulated by GHRH and somatostatin; drives hepatic IGF-1 (JAK2/STAT5b), growth, muscle anabolism, and lipolysis; acromegaly from GH-secreting adenoma; GH deficiency causes growth failure and metabolic syndrome.

Also known as: GH, growth hormone, somatotropin, hGH, somatotroph, acromegaly, gigantism, GH deficiency, GHRH, somatostatin, IGF-1 axis, pegvisomant
