متن کاملINFORMATIONAL GUIDE PROGESTERONE METABOLITES PREMENOPAUSE Urinary Progesterone Metabolites in Premenopausal Women Not Supplementing with Progesterone
The urinary progestogen metabolites included in our profiles encompass the primary urinary metabolite, pregnanediol (Pgdiol), and four other more minor metabolites that belong to the pregnane (Allopregnanolone, Allo-pregnanediol) and pregnene (3α-dihydroprogesterone, 20α-dihydroprogesterone) categories. In postmenopausal women the level of pregnanediol is expected to be much lower than in preme...
متن کاملProgesterone regulation of the progesterone receptor in rat gonadotropes.
For rat pituitary cells, progesterone receptor (PR) protein localizes to gonadotropes and PR messenger RNA is induced by E2 and rapidly but transiently down-regulated by progesterone. Here we quantitatively establish the down-regulatory effect of progesterone on PR protein and evaluate possible mechanisms. Nuclear PR-immunoreactivity (PR-IR) in gonadotropes, identified by dual immunofluorescenc...
