Title: Increased number of beta-adrenergic receptors on cells of the rat adenohypophysis after thyroid hormone administration. Author: Pacák K, Nedvídková J, Stolba P, Schreiber V. Journal: Physiol Bohemoslov; 1990; 39(3):249-52. PubMed ID: 2171004. Abstract: The authors studied the effect of administration of thyroid hormones on the beta-adrenergic receptors of rat adenohypophyseal cells. The administration of triiodothyronine and thyroxine was followed by an increase in specific binding for 3H-dihydroalprenolol. No significant differences were found in cyclic adenosine monophosphate levels before and after isoprenaline stimulation. The significance of changes in these receptors for the hyperplastic reaction after oestrogens is discussed with reference to the inhibitory effect of the thyroid hormones on hyperplasia of the adenohypophyseal cells after the administration of oestradiol.[Abstract] [Full Text] [Related] [New Search]
