Comparison of transcriptional synergy of estrogen receptors α and β from multiple tandem estrogen response elements

Molecular and Cellular Endocrinology, 2000
Estrogen receptors alpha and beta (ERalpha and ERbeta) act as ligand-dependent transcriptional enhancers. We reported that ERalpha induces synergistic activation of luciferase reporter gene activity in response to E(2) from three or four tandem copies of a consensus estrogen response element (ERE) in transiently transfected MCF-7 cells.

Absence of estrogen receptor-β expression in metastatic ovarian cancer

Obstetrics & Gynecology, 2000
To evaluate the expression of estrogen receptor (ER)alpha and ERbeta mRNA and protein in normal ovarian tissue and primary and metastatic tumors.Estrogen receptor alpha and ERbeta expression was studied in normal ovarian biopsies (n = 9) and primary (n = 8) and metastatic ovarian epithelial cancers (n = 8).

Rapid actions of estrogens in GH3/B6 pituitary tumor cells via a plasma membrane version of estrogen receptor-α

Steroids, 1999
The focus of our work on rapid actions of estrogens has been on the immuno-identification of a membrane version of the estrogen receptor-alpha (mERalpha) and the correlation of the presence of this receptor to the rapid secretion of prolactin in pituitary tumor cells. We demonstrated the mERalpha by both fluorescence and immuno-enzyme-cytochemistry and
