Detection of somatotropin receptors on human monocytes
Immunology Letters, 1990The expression of somatotropin receptors on human peripheral blood monocytes was investigated. Binding of [125I]somatotropin to human monocytes was found to be specific and saturable. The binding was rapid and time-dependent, and was abolished by pretreatment of monocytes with trypsin.

Specific binding sites for porcine somatotropin (pST) have been identified in pig liver microsomal membranes. Little information, however, is available about the size and number of ST receptor (ST-R) forms present. Therefore, the present study was conducted to characterize ST-R in pig liver using two approaches.

Peculiarities of cell and tissue distribution of somatotropin receptors in liver cells of male rats and intact, pregnant, and estrogenized female rats is studied using an indirect immunohistochemical method. Experiments reveal equal and positively regulated by female hormones expression of somatotropin receptors in all hepatocytes.

Corticosterone (CORT) can stimulate growth hormone (GH) secretion on embryonic day (e) 12 in the chicken. However, CORT failed to induce GH secretion on e20 in a single report, suggesting that regulation of GH production changes during embryonic development. Secretion in response to CORT during embryonic development is modulated by the thyroid hormones

A comparative study of effects of Mg2+ ions on specific and competitive binding of the bovine somatotropic hormone (STH) and bovine prolactin (PL) with cells of cow granulosum is carried out. It is found that Mg2+ increases the level of specific binding of 125I-PL with the cells at concentrations from 1 to 70 mM and decreases the level of specific ...

It is generally accepted that hormone receptors are protein molecules which are not ubiquitous but are found in or attached to a target cell. In the interaction of a hormone with its receptor on target cell membranes, the initial step is the specific binding of the hormone with the receptor.

Prepubertal gilts of obese (n = 24) or lean (n = 24) genetic lines were injected (s.c.) daily with 0, 2, or 4 mg of porcine somatotropin (pST) for 6 wk starting at 160 d of age to determine whether pST affects follicular function. Blood and ovaries were collected at slaughter 24 h after the last injection. Surface follicles greater than or equal to 1.0

Twenty barrows were designated as fast-growing (FG) and their littermates designated as slow-growing (SG) based on birth, weaning, and 56-d weight. Half of each group received 70 micrograms of porcine somatotropin (pST)/kg BW daily beginning at 40 kg BW.
