|---|---|
| thyrotropin-releasing hormone | <protein> See thyrotrophic releasing hormone. (18 Nov 1997) |
| thyrotropin-releasing hormone stimulation test | TRH stimulation test, a test of pituitary response to injection of thyrotropin-releasing hormone, which normally stimulates pituitary secretion of thyroid-stimulating hormone (TSH, thyrotropin), used primarily to distinguish pituitary from hypothalamic causes of thyroid disorders; TSH does not rise in cases of pituitary dysfunction, but does rise in cases of hypothalamic disorders. (05 Mar 2000) |
| tropic hormone | <endocrinology> A peptide hormone that stimulates a specific target gland to secrete adifferent set of hormones. (09 Oct 1997) |
| erythropoietic hormone | Generally, any hormone that promotes the formation of red blood cells, e.g., testosterone, Synonym: erythropoietin. (05 Mar 2000) |
| juvenile hormone | <endocrinology> A hormone found in insects which affects the balance between mature and juvenile attributes of certain tissues at each moult. In particular, the imaginal discs of many larval insects only develop into adult wings, sexual organs or limbs when blood juvenile hormone levels fall below a threshold level. There is a complex interaction between juvenile hormone and ecdysone. Synthetic analogues of JH include farnesol and methoprene, which have been tested for insecticide potential (known, with diflubenzuron, as Insect Growth Regulators, IGRs. See: chitin). (18 Nov 1997) |
| juvenile hormone esterase | <enzyme> Amino acid sequence has been determined Registry number: EC 3.1.1.- Synonym: jh esterase, insect jhe (26 Jun 1999) |
| lactation hormone | <protein> Pituitary lactogenic hormone (23 kD) Synthesised on endoplasmic reticulum bound ribosomes as preprolactin that has an N terminal signal peptide that is cleaved from the mature form. The conversion of preprolactin to prolactin has been much used as an assay for membrane insertion. (18 Nov 1997) |
| lactogenic hormone | <protein> Pituitary lactogenic hormone (23 kD) Synthesised on endoplasmic reticulum bound ribosomes as preprolactin that has an N terminal signal peptide that is cleaved from the mature form. The conversion of preprolactin to prolactin has been much used as an assay for membrane insertion. (18 Nov 1997) |
| follicle-stimulating hormone | <hormone> An acidic glycoprotein secreted by the anterior pituitary gland. In women, follicle-stimulating hormone stimulates the development of ovarian follicles (eggs) and stimulates the release of oestrogens. In men, follicle-stimulating hormone stimulates the production of sperm. Abnormal follicle-stimulating hormone levels may be seen in the following conditions: hypopituitarism, Klinefelter syndrome, polycystic ovary disease, Turner's syndrome and ovarian failure. Synonym: follitropin. Acronym: FSH (12 Sep 2002) |
| follicle-stimulating hormone-releasing factor | A decapeptide of hypothalamic origin capable of accelerating pituitary secretion of follitropin. Synonym: follicle-stimulating hormone-releasing factor, follicle-stimulating hormone-releasing hormone. Origin: follicle-stimulating hormone + L. Libero, to free, + -in (05 Mar 2000) |
| follicular hormone | estrone |
| lipid-mobilizing hormone | <protein> Polypeptide hormone (_ form: 9894D, 91 residues, _ form has only residues 1-58 of _) from the pituitary hypophysis, that is of particular interest because it is the precursor of endorphins, which are released by proteolysis. Promotes lipolysis and acts through the adenylyl cyclase system. Part of the ACTH group of hormones. (18 Nov 1997) |
| lipotropic hormone | <protein> Polypeptide hormone (_ form: 9894D, 91 residues, _ form has only residues 1-58 of _) from the pituitary hypophysis, that is of particular interest because it is the precursor of endorphins, which are released by proteolysis. Promotes lipolysis and acts through the adenylyl cyclase system. Part of the ACTH group of hormones. (18 Nov 1997) |
| local hormone | A metabolic product secreted by one set of cells that affects the function of nearby cells; an autacoid; e.g., prostaglandins and neurotransmitters. (05 Mar 2000) |
