growth hormone
growth hormone (GH; somatotrophin) A hormone, secreted by the mammalian pituitary gland, that stimulates protein synthesis and growth of the long bones in the legs and arms. It also promotes the breakdown and use of fats as an energy source, rather than glucose. Production of growth hormone is greatest during early life. Its secretion is controlled by the opposing actions of two hormones from the hypothalamus:
growth hormone releasing hormone (
somatoliberin), which promotes its release; and
somatostatin, which inhibits it. Overproduction of
human growth hormone (
hGH) results in gigantism in childhood and
acromegaly in adults; underproduction results in dwarfism.
Bovine somatotrophin (
BST) has been used to increase milk and meat production in cattle.
