| insulin-like growth-factor-binding proteins | A family of soluble proteins that bind insulin-like growth factors and modulate their biological actions at the cellular level. (int j gynaecol obstet 1992;39(1):3-9) (12 Dec 1998) |
| insulin-like growth factor I | <chemical> A well-characterised basic peptide believed to be secreted by the liver and to circulate in the blood. It has growth-regulating, insulin-like, and mitogenic activities. This growth factor has a major, but not absolute, dependence on somatotropin. It is believed to be mainly active in adults in contrast to insulin-like growth factor II, which is a major foetal growth factor. Chemical name: Insulin-like growth factor I (12 Dec 1998) |
| insulin-like growth factor II | <chemical> A well-characterised neutral peptide believed to be secreted by the liver and to circulate in the blood. It has growth-regulating, insulin-like and mitogenic activities. The growth factor has a major, but not absolute, dependence on somatotropin. It is believed to be a major foetal growth factor in contrast to insulin-like growth factor I, which is a major growth factor in adults. Chemical name: Insulin-like growth factor II (12 Dec 1998) |
| integrin modulating factor 1 | <chemical> A lipid that alters the function of leukocyte integrins; may be an unsaturated fatty acid or an isoprenoid acid Synonym: imf 1, imf-1 (05 Dec 1998) |
| intrinsic factor | A mucoprotein normally secreted by the epithelium of the stomach and that binds vitamin B12, the intrinsic factor/B12 complex is selectively absorbed by the distal ileum, though only the vitamin is taken into the cell. (18 Nov 1997) |
| osteoclast activating factor | A lymphokine that stimulates bone resorption and inhibits bone-collagen synthesis. (05 Mar 2000) |
| termination factor | <molecular biology> Any of several proteins in the cytosol that cut a completed polypeptide loose from a ribosome. (13 Jan 1998) |
| testis-determining factor | The product of a gene on the short arm of the Y chromosome that is responsible for production of testes. (05 Mar 2000) |
| thymic factor, circulating | <chemical> A thymus-dependent nonapeptide found in normal blood. Stimulates the formation of e rosettes and is believed to be involved in T-cell differentiation. Chemical name: Thymulin (12 Dec 1998) |
| thymic lymphopoietic factor | A glycoprotein (MW about 12,000) that has been extracted from thymus; this thymus-produced hormone(s) confers immunological competence on thymus-dependent cells and induces lymphopoiesis. (05 Mar 2000) |
| thyroid-stimulating hormone-releasing factor | <protein> See thyrotrophic releasing hormone. (18 Nov 1997) |
| thyrotoxic complement-fixation factor | A form of thyrotoxin; an antigen found most readily in thyroid tissue from thyrotoxic individuals; known to be chemically and immunologically distinct from thyroglobulin, and fixes complement when combined with antibody related to the gamma-globulin fraction of serum. With the exception of extremely small concentrations, the antigen is rarely found in normal glands or in diseased glands that are not associated with thyrotoxicosis; it is probably an intracellular substance (possibly a constituent of the "microsomal fraction"), and does not contain iodine in significant quantity. Not related to the complement-fixation reaction occurring with serum in Hashimoto's disease, in which the antigen is thyroglobulin. (05 Mar 2000) |
| thyrotropin-releasing factor | Former name for thyrotropin-releasing hormone. (05 Mar 2000) |
