The aim of this study was to examine the role of sex steroid hormones in the regulation of
intracellular progesterone receptors (PR) in the rabbit central nervous system. We …

Progesterone receptors (PRs) are known to exist in two forms: a larger molecular, form B,
and a smaller one, form A. Rat PR cDNA corresponding to the region around the translation …

OBJECTIVE: To quantify expression of progesterone receptor (PR) messenger RNA (mRNA)
isoforms in fetal membranes, and to determine whether these levels change in culture …

The presence of progesterone receptors (PR) in the human placenta has been
demonstrated using the reverse transcriptase–polymerase chain reaction technique. It was …

Objective: To study the functional differences between the two progesterone receptor
isoforms (hPRA and hPRB) in human endometrial cancer, two new endometrial carcinoma …

Human epithelial ovarian neoplasm is well‐known to be sex steroid‐related, but the
possible biological significance of progesterone actions in these tumors remains …

Estrogens (ie estradiol) and progestins (ie progesterone) may act as local regulators of
ovarian function in various species. This study tested the hypothesis that if progesterone and …

We characterized the expression pattern of progesterone receptor (PR) in two regions of the
oviduct (ampullae and isthmus), and the uterus (epithelium and stroma) of the rabbit …

Recent evidence suggests that progesterone is required for ovulation, luteinization, and the
maintenance of luteal structure and function in primates. Progesterone action is mediated by …

Progesterone receptors in nuclei and cytosols from the hypothalamus and anterior
hypophysis of oestrogen-primed immature and mature female rats were investigated. In the …
