| epidermal growth factor | <growth factor> A mitogenic polypeptide initially isolated from male mouse submaxillary gland. The name refers to the early bioassay, but epidermal growth factor is active on a variety of cell types, especially but not exclusively epithelial. Human equivalent originally named urogastrone owing to its hormone activity. Acronym: EGF (18 Nov 1997) |
|---|---|
| epidermal growth factor receptor protein-tyrosine kinase | <enzyme> The catalytic protein-tyrosine kinase domain found on the cytoplasmic beta-portion of epidermal growth factor receptor. Registry number: EC 2.7.1.- (12 Dec 1998) |
| epidermal growth factor-urogastrone | <chemical> Single chain, nonhelical, acidic polypeptides of about 52 amino acids found in most mammals. Epidermal growth factor and urogastrone are not identical but seem to share biological acivities. They promote growth of, and cell proliferation in, certain tissues, especially epidermal structures and inhibit acid secretion by the stomach. They have been used to treat gastrointestinal ulcers. Chemical name: Epidermal growth factor (12 Dec 1998) |
| excess annual growth | The amount by which new forest growth exceeds removal in a year. The annual quantity of wood produced in a forest in excess of market demand. (05 Dec 1998) |
| exponential growth | <biology> A rate of growth of an organism, a part of an organism, or a population of organisms which, when graphed, produces an exponential or logarithmic curve. Such a rate occurs, for example: during the exponential growth phase, when a population of bacterial (or other) cells divide at a constant rate so that the total number of cells doubles with each division. (09 Oct 1997) |
| keratinocyte growth factor | <growth factor> A growth factor structurally related to fibroblast growth factor. (18 Nov 1997) |
| urban growth boundary | A land use boundary surrounding a city. Urban land uses are permitted within the urban growth boundary. (05 Dec 1998) |
| foetal growth retardation | The failure of a foetus to maintain its expected growth potential at any gestational stage. (12 Dec 1998) |
| adipokinetic hormone | An anterior pituitary hormone that causes mobilization of fat from adipose tissue. Synonym: adipokinetic hormone. (05 Mar 2000) |
| adrenal androgen-stimulating hormone | A putative pituitary hormone that may be responsible for increased secretion of adrenal androgens at the time of puberty. (05 Mar 2000) |
| adrenocorticotrophic hormone | <endocrinology> A peptide hormone that is produced by the anterior pituitary gland. It stimulates the adrenal cortex to secrete glucocorticoid hormones, which help cells synthesise glucose, catabolize proteins, mobilizefree fatty acids and inhibit inflammation in allergic responses. (10 May 1997) |
| adrenocorticotropic hormone | The hormone of the anterior lobe of the hypophysis which governs the nutrition and growth of the adrenal cortex, stimulates it to functional activity, and also possesses extraadrenal adipokinetic activity; it is a polypeptide containing 39 amino acids, but exact structure varies from one species to another; sometimes prefixed by a to distinguish it from beta-corticotropin. The first thirteen amino acids at the N-terminal region are identical to alpha-melanotropin. Synonym: adrenocorticotropin, adrenotropic hormone, adrenotropin, corticotropic hormone, corticotropin. (05 Mar 2000) |

The first thirteen amino acids at the N-terminal region are identical to alpha-melanotropin. Synonym: adrenocorticotropin, adrenotropic hormone, adrenotropin, corticotropic hormone, corticotropin. (05 Mar 2000) |
| androgenic hormone | <endocrinology> A male (masculinising) hormone. These medications (testosterone, methyltestosterone, fluoxymesterone, danazol) are used to treat androgen deficiency, delayed puberty in males and some forms of breast cancer. (27 Sep 1997) |
| anterior pituitary-like hormone | A glycoprotein with a carbohydrate fraction composed of d-galactose and hexosamine, extracted from the urine of pregnant women and produced by the placental trophoblastic cells; its most important role appears to be stimulation, during the first trimester, of ovarian secretion of the oestrogen and progesterone required for the integrity of conceptus; it appears to play no significant role in the last two trimesters of pregnancy, as the oestrogen and progesterone are then formed by the placenta. Synonym: anterior pituitary-like hormone, choriogonadotropin, chorionic gonadotropic hormone, chorionic gonadotrophic hormone, placenta gonadotropin, placentagonadotropin. (05 Mar 2000) |
