We and others have shown previously that progesterone receptors (PR) form homodimers in
solution in the absence of DNA and that dimers are the preferential form of receptor that …

Progesterone acting through two isoforms of the progesterone receptor (PR), PRA and PRB,
regulates proliferation and differentiation in the normal mammary gland in mouse, rat, and …

A series of rat and mouse monoclonal antibodies to the human progesterone receptor (PR)
has recently been produced. These antibodies were used for the immunocytochemical …

Materials and Methods Description of Probes. The probe used for screening the cDNA
library, hPR54, was a gift from Dr. BW O'Malley and contained a 2.6-kb fragment of the …

Previously we reported the identification of two unique progesterone receptor (PR)
messenger RNA transcripts that encode a smaller PR isoform, termed the C-receptor (PRc) …

We have previously reported the identification of seven in vivo phosphorylation sites in the
amino-terminal region of the human progesterone receptor (PR). From our previous in vivo …

In normal mouse mammary gland, the mitogenic action of progesterone (P) is mediated by
two P receptor (PR) isoforms, PRA and PRB. PRA is predominantly expressed in the adult …

Estrogen receptors (ER) and progesterone receptors (PgR) were studied
immunohistochemically using specific antireceptor monoclonal antibodies in uterine tissue …

Progesterone receptor (PR) isoforms expression was determined in the hypothalamus, the
preoptic area, the hippocampus and the frontal cerebral cortex of the rat at 12: 00 h on each …

The human progesterone receptor (hPR) cDNA, synthesized from T47D breast cancer cells,
and the hPR gene 5′‐flanking region were cloned and sequenced. Comparison of the …
