Adding dichotomous tumor ER or PR status to the panel of standard predictors did not improve both model discrimination and calibration.<b>Conclusions:</b> Obesity may be associated with greater endometrial tumor expression of ER and PR.
CYP1B1 gene polymorphisms have higher risk for endometrial cancer, and positive correlations with estrogen receptor alpha and estrogen receptor beta expressions.
Coordinate expression of Cdc25B and ER-alpha is frequent in low-grade endometrioid endometrial carcinoma but uncommon in high-grade endometrioid and nonendometrioid carcinomas.
Relative proportions of the estrogen receptor (ER) alternatively spliced mRNA variants from the proximal (A) and distal (B) promoter pre-mRNA transcripts were measured in normal human uterus, an endometrial tumor, and in T47D, MCF-7, and BT-20 breast tumor cell lines.
