Wilms’ Tumor 1 Suppressor Gene Mediates Antiestrogen Resistance via Down-Regulation of Estrogen Receptor-A Expression in Breast Cancer Cells
The antiestrogen tamoxifen has been used in the treatment of hormone-responsive breast cancer for over a decade. The loss of estrogen receptor (ER) expression is the most common mechanism for de novo antiestrogen resistance. Wilms’ tumor 1 suppressor gene (WT1) is a clinically useful marker that is associated with poor prognosis in breast cancer patients; its high level expression is frequently...

متن کاملEstrogen Receptor-Alpha 36 Mediates Mitogenic Antiestrogen Signaling in ER-Negative Breast Cancer Cells
It is prevailingly thought that the antiestrogens tamoxifen and ICI 182, 780 are competitive antagonists of the estrogen-binding site of the estrogen receptor-alpha (ER-α). However, a plethora of evidence demonstrated both antiestrogens exhibit agonist activities in different systems such as activation of the membrane-initiated signaling pathways. The mechanisms by which antiestrogens mediate e...
متن کاملSelective inhibition of estrogen-regulated gene expression in vivo by the pure antiestrogen ICI 182,780.
Estrogen-stimulated cell proliferation is thought to be mediated by the induction of growth-regulatory factors. Abnormal regulation of such factors may be associated with tumorigenesis. Two such factors, vascular endothelial growth factor and c-fos, are rapidly induced in the uterus by estrogens. We show that the induction of these transcripts by 17beta-estradiol or tamoxifen is selectively blo...
متن کاملRegulation of estrogen and progestin receptor concentrations in an experimental rat prostatic carcinoma by estrogen, antiestrogen, and progesterone.
In order to assess prostatic tissue as a target for receptor-mediated estrogen action, we have examined the regulation of estrogen (ER) and progestin receptors (PgR) by estrogen, antiestrogen, and progesterone in cytosolic and nuclear fractions of the R3327H (Dunning) prostatic adenocarcinoma of the rat. Twenty micrograms diethylstilbestrol (DES) with or without 800 micrograms tamoxifen (Tam) w...
