Distribution of estrogen and progesterone receptors isoforms in endometrial cancer
BACKGROUND 70-80% of sporadic endometrial carcinomas are defined as endometrioid carcinoma (EC). Early-stage, well differentiated endometrial carcinomas usually retain expression of estrogen and progesterone receptors (ER and PR, respectively), as advanced stage, poorly differentiated tumors often lack one or both of these receptors. Well-described EC prognosis includes tumor characteristics, s...
متن کاملProgesterone and progesterone receptors in experimental breast cancer.
in ER-positive tumors would indicate that the tumor is capa ble of synthesizing at least 1 end product under estrogen regulation and may therefore be endocrine responsive (8). Although the hypothesis assumes that PGR levels in breast tumors, like those in the uterus, are under estrogen control, this priming effect has never been demonstrated. In this paper we show that PGR in the DMBA-induced m...
متن کاملExpression of Estrogen and Progesterone Receptors in Papillary Thyroid Carcinoma
Background: Papillary thyroid carcinoma (PTC), occurs mostly in women and sex hormones may play a role in the pathogenesis and clinical course. The objective of this study was to determine the status and prevalence of estrogen and progesterone receptors in PTC with regard to age, gender, tumor size and lymph node involvement. Methods: Immunohistochemical stains were performed on 92 tissue bl...
متن کاملProgesterone receptors on human spermatozoa.
Progesterone, primarily recognized as a female steroid hormone, is reported to affect several sperm functions especially capacitation, motility and acrosome reaction. These effects of progesterone on the spermatozoa are mediated via the progesterone binding sites/progesterone receptor (PR) on the acrosomal membrane. These receptors in response to progesterone increase the intercellular Ca2+ lev...
متن کاملReproductive functions of progesterone receptors.
The steroid hormone progesterone plays a central role in the reproductive events associated with pregnancy establishment and maintenance. Physiological effects of progesterone are mediated by interaction of the hormone with specific intracellular progesterone receptors (PRs) that are expressed as two protein isoforms, PR-A and PR-B. Both proteins arise from the same gene and are members of the ...
