The effects of growth hormone on blood pressure and renin secretion in hypophysectomized rats.

abstract：:TSH is the most important biomarker in the interpretation of thyroid function in man. Its levels are determined by circulating thyroid hormone (TH) levels that feed back centrally to regulate the expression of the subunits that comprise TSH from the pituitary. The nuclear corepressor 1 (NCoR1), is a critical coregulat...

Here we further explore the cross talk between GnRH and the PG rec...
