| thyroid hormone aminotransferase | <enzyme> Chemical name: 3,5-dinitrotyrosine aminotransferase Registry number: EC 2.6.1.26 Synonym: triiodothyrone aminotransferase, triiodothyronine aminotransferase (26 Jun 1999) |
|---|---|
| thyroid hormone resistance syndrome | <syndrome> An inherited syndrome of peripheral resistance to thyroid hormones, transmitted as an autosomal recessive trait, characterised by increased serum concentrations of thyroxine and triiodothyronine, increased thyroid hormone binding ratio, and normal to slightly increased thyroid-stimulating hormone and its response to thyrotropin-releasing hormone. The affected persons are euthyroid to slightly hypothyroid. The absence of hypermetabolism and the presence of possible hypothyroidism indicate the existence of partial resistance to the peripheral action of thyroid hormone. (12 Dec 1998) |
| thyroid releasing hormone | <endocrinology> Thyroid releasing hormone (TRH) is a byproduct of the hypothalamus and serves to stimulate the pituitary gland to produce thyroid stimulating hormone (TSH). TRH is produced by the hypothalamus when thyroid hormone (T3 and T4) blood levels are low. (27 Sep 1997) |
| thyroid stimulating hormone | <endocrinology> Polypeptide hormone (28 kD), secreted by the anterior pituitary gland, that activates cyclic AMP production in thyroid cells leading to production and release of the thyroid hormones (T4 and T3). T4 and T3 blood levels feedback on the pituitary gland and decrease thyroid stimulating hormone production when T3 and T4 levels are high. (27 Sep 1997) |
| thyroid-stimulating hormone | thyroid stimulating hormone |
| thyroid-stimulating hormone-releasing factor | <protein> See thyrotrophic releasing hormone. (18 Nov 1997) |
| thyroid-stimulating hormone stimulation test | TSH stimulating test, a test that measures the uptake of 131I in the thyroid gland before and after administration of thyroid-stimulating hormone; useful in distinguishing primary hyperthyroidism (increased TSH serum concentration) from secondary or tertiary hyperthyroidism (low TSH serum concentrations). (05 Mar 2000) |
| thyrotrophic releasing hormone | <endocrinology> Tripeptide (pyroGlu His Pro NH2) that releases thyrotrophin from the anterior pituitary by stimulating adenyl cyclase. May also have neurotransmitter and paracrine functions. (18 Nov 1997) |
| thyrotropic hormone | thyroid stimulating hormone |
| 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).

| juvenile hormone esterase | <enzyme> Amino acid sequence has been determined Registry number: EC 3.1.1.- Synonym: jh esterase, insect jhe (26 Jun 1999) |
