| neoplasms, hormone-dependent | Certain tumours that 1) arise in organs that are normally dependent on specific hormones and 2) are stimulated or caused to regress by manipulation of the endocrine environment. (12 Dec 1998) |
|---|---|
| steroid hormone | <endocrinology> A group of structurally related hormones, based on the cholesterol molecule. They control sex and growth characteristics, are highly lipophilic and are unique in that their receptors are in the nucleus, rather than on the plasma membrane. Examples: testosterone, oestrogen. (18 Nov 1997) |
| sympathetic hormone | <protein> A neurohormone, such asepinephrine, produced in response to stimulationof the sympathetic nervous system and which acts as a chemical mediator invarious organs. (09 Oct 1997) |
| syndrome of inappropriate secretion of antidiuretic hormone | Continued secretion of antidiuretic hormone despite low serum osmolality and expanded extracellular volume. (05 Mar 2000) |
| inappropriate hormone | A hormone formed by tissue outside the normal endocrine site of production; e.g., adrenocorticotropic hormone produced by a bronchogenic carcinoma. Synonym: inappropriate hormone. (05 Mar 2000) |
| interstitial cell-stimulating hormone | <protein> Synonym for luteinising hormone. (18 Nov 1997) |
| oestrogenic hormone | <pharmacology> A female hormone produced by the ovaries (or an equivalent hormone synthesised in the laboratory). Oestrogen deficiency can lead to osteoporosis. (12 Dec 1998) |
| ovarian hormone | <protein> Polypeptide hormone produced by corpus luteum and found in the blood of pregnant animals. Acts, as its name suggests, to cause muscle relaxation during parturition. Human relaxin has an A chain of 24 amino acids and a B chain of 29. Has structural similarity to insulin. (18 Nov 1997) |
| thymic hormone | <endocrinology> One of the hormones produced by the thymus that are believed to play a role in the maturation of T-lymphocytes and overall modulation of the immune system. Versions of several of them are under study as anti-HIV therapies-thymopentin and thymosin-a1 in particular. (09 Oct 1997) |
| ectopic hormone | A hormone formed by tissue outside the normal endocrine site of production; e.g., adrenocorticotropic hormone produced by a bronchogenic carcinoma. Synonym: inappropriate hormone. (05 Mar 2000) |
| thyroid hormone | <endocrinology> Thyroxine and tri iodothyronine are hormones secreted by the thyroid gland in vertebrates. These iodinated aromatic amino acid compounds influence growth and metabolism and, in amphibia, metamorphosis. The hormone calcitonin which has hypocalcaemic effects is also of thyroid origin but is not usually classed with thyroxine and tri iodothyronine as a thyroid hormone. (18 Nov 1997) |
| 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) |
