Multiple progesterone receptor (PR) isoforms may explain in part the complex and diverse
biological actions of progestins. Recent studies demonstrate that the human 116 kDa B …

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) …

In humans, the biological response to progesterone is mediated by two distinct forms of the
progesterone receptor (human (h) PR-A, 94 kDa and hPR-B, 114 kDa). These two isoforms …

When antagonist-occupied steroid receptors have agonist-like effects, the clinical
consequences are grave. We present evidence that human progesterone B-receptors …

The steroid hormone progesterone plays a central role in the reproductive events associated
with pregnancy establishment and maintenance. Physiological effects of progesterone are …

The biological response to progesterone is mediated by two distinct forms of the human
progesterone receptor (hPR-A and hPR-B). In most cell contexts, hPR-B functions as a …

The steroid hormone, progesterone, is a central coordinator of all aspects of female
reproductive activity. The physiological effects of progesterone are mediated by interaction …

In humans, the biological response to progesterone is mediated by two forms of the
progesterone receptor (hPR-A; 94kDa and hPR-B; 114kDa). These two isoforms are …

The progesterone receptor (PR) occurs in two major forms, the full-length PRB and the
amino-truncated PRA, which lacks 164 amino-terminal residues. PRB functions as a strong …

Full transcriptional activation by steroid hormone receptors requires functional synergy
between two transcriptional activation domains (AF) located in the amino (AF-1) and …
