Phosphorylation and Progesterone Receptor Function
The Journal of Steroid Biochemistry and Molecular Biology, 1994Four phosphorylation sites have been identified in the chicken progesterone receptor. Two of these sites exhibit basal phosphorylation which is enhanced upon treatment with hormone and two of the sites are phosphorylated in response to hormone. Mutation of one of these hormone dependent sites, Ser530 to Ala530, causes a decrease in transcriptional ...

Progesterone antagonists and progesterone receptor modulators: an overview
Steroids, 2003Since the original description of the structure of the antiprogestin, mifepristone, was published, numerous related compounds have been synthesized which may function as progesterone antagonists (PAs) or progesterone receptor modulators (PRMs). The latter are mixed agonists-antagonists.

Progesterone receptors regulate gallbladder motility
Journal of Surgical Research, 1988The increased incidence of gallstones in multiparous women may be related to hormonal effects on the gallbladder and its contractility. The occurrence of estrogen and progesterone receptors were studied in the gallbladders of three groups of female guinea pigs (normals, oophorectomized, and oophorectomized treated with estrogen + progesterone for 14 ...

Progesterone receptors in breast fibroadenomas
Journal of Steroid Biochemistry, 1979Abstract Cytosol progesterone receptors (P-R) were measured in breast fibroadenomas from 88 women, and their levels were compared to the tumor epithelial cell density and estradiol receptor levels (E-R). Three groups of fibroadenoma were distinguished: type I with a high epithelial cell density (n= 18), type III (n = 46) with low epithelial cell ...

Progesterone Receptors and Ovulation
2010The steroid hormone, progesterone, plays a critical role in the regulation of female ovulation. The physiological effects of progesterone are mediated by two nuclear receptor transcription factors, PR-A and PR-B, which are produced from a single gene and upon binding progesterone regulate the expression of specific gene networks in reproductive tissues.

Progesterone and the progesterone receptor.
The Journal of reproductive medicine, 2001During the 1990s, extensive research has effectively mapped the progesterone receptor-mediated actions of progesterone and has more recently uncovered nonreceptor-mediated effects--the effect of progesterone on uterine sensitivity to oxytocin, for example, involves direct, nongenomic progesterone action on the uterine oxytocin receptor.
