چکیده

A site-directed anti-peptide antibody (anti-hGHRHRc18) was generated against the cytoplasmic tail of human GHRH receptor. The dissociation constant (Kd) and the antibody binding site (AbT) of anti-hGHRHRc18 were 2.5 nmol/l and 0.54 nmol/l, respectively. In an immunoblotting experiment, affinity-purified anti-hGHRHRc18 specifically recognized a single 50-kDa protein in human pituitary. In a screening of the expression of GHRH receptor protein in extra-pituitary tissues, only human kidney showed a single 52-kDa protein. Our results suggest that the GHRH receptor protein exhibits tissue-specific molecular heterogeneity.

Purification of Large Quantities of Biologically Active Recombinant Human Growth Hormone

Production and purification of human growth hormone using a simple method was studied in two recombinantEscherichia coli, D7-5 and C27-2 strains. The r-hGH was expressed in the form of inclusion body in a batchfermentation process and purified to 99% purity using a procedure based on acid precipitation of the hostderived proteins and other impurities. The effect of the pH and ...

Neither bovine somatotropin nor growth hormone-releasing factor alters expression of thyroid hormone receptors in liver and mammary tissues.

Physiological effects of thyroid hormones are mediated primarily by binding of triiodothyronine to specific nuclear receptors. Organ-specific changes in production of triiodothyronine from its prohormone, thyroxine, have been hypothesized to target the action of thyroid hormones on the mammary gland and play a role in mediating or augmenting a galactopoietic response to bovine somatotropin (bST...

Molecular analysis of rat pituitary and hypothalamic growth hormone secretagogue receptors.

GH release is thought to occur under the reciprocal regulation of two hypothalamic peptides, GH releasing hormone (GHRH) and somatostatin, via their engagement with specific cell surface receptors on the anterior pituitary somatotroph. In addition, GH-releasing peptides, such as GHRP-6 and the nonpeptide mimetics, L-692,429 and MK-0677, stimulate GH release through their activation of a distinc...
