Progesterone 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...
متن کاملProgesterone receptor modulators.
The review1 on ‘Progesterone receptor modulators in gynaecological practice’ in the April 2010 issue of the Journal is a valuable contribution to the available literature on a currently important subject. In the section on ‘Contraception’ the authors have dealt at length with mifepristone. Since the latter is not licensed for postcoital contraception, it would have been appreciated if the autho...
متن کاملThe Effect of Imbalanced Progesterone Receptor-A/-B Ratio on Gelatinase Expressions in Endometriosis
Objective Objective: Gelatinases degrade extracellular matrix (ECM) components to make physiological remodeling and contribute to pathological tissue destruction in endometriosis. It is known that gelatinases’ function is resistant to suppression by progesterone in endometriosis. The ability of progesterone to impact gene expression depends on the progesterone receptor-A/-B (PR-A/PR-B) ratio. A...
متن کاملCloning of the chicken progesterone receptor.
Monospecific antibodies directed against the chicken progesterone receptor (PR) form B were used to screen a randomly primed phage lambda gt11 cDNA expression library prepared from size-fractionated chicken oviduct mRNA. Two independent immunoreactive clones, lambda cPR1 and lambda cPR2, were isolated. Antibodies selected from anti-PR form B antiserum on matrices of lambda cPR1 and lambda cPR2 ...
متن کاملHeterotetrameric structure of the human progesterone receptor.
Nonactivated progesterone receptors in extracts of human T47D mammary carcinoma cells were investigated. Chemical cross-linking with dimethyl suberimidate resulted in complete stabilization of the A and B receptors with an average molecular mass of 340 kDa. For analyzing the subunit structure, we concentrated on the larger B receptor, which was separated from the A form by immunoaffinity chroma...
