Arsenic Induces Functional Re-Expression of Estrogen Receptor α by Demethylation of DNA in Estrogen Receptor-Negative Human Breast Cancer
Estrogen receptor α (ERα) is a marker predictive for response of breast cancers to endocrine therapy. About 30% of breast cancers, however, are hormone- independent because of lack of ERα expression. New strategies are needed for re-expression of ERα and sensitization of ER-negative breast cancer cells to selective ER modulators. The present report shows that arsenic trioxide induces reactivate...
متن کاملEstrogen receptor α inhibitor activates the unfolded protein response, blocks protein synthesis, and induces tumor regression.
Recurrent estrogen receptor α (ERα)-positive breast and ovarian cancers are often therapy resistant. Using screening and functional validation, we identified BHPI, a potent noncompetitive small molecule ERα biomodulator that selectively blocks proliferation of drug-resistant ERα-positive breast and ovarian cancer cells. In a mouse xenograft model of breast cancer, BHPI induced rapid and substan...
متن کاملAntagonists Selective for Estrogen Receptor α.
To develop compounds that are antagonists on ER , but not ER , we have added basic side-chains typically found in nonsteroidal antiestrogens to pyrazole compounds that bind with much higher affinity to ER than to ER . In this way we have developed basic side-chain pyrazoles (BSC-pyrazoles) that are high affinity, potent, selective antagonists on ER . These BSCpyrazoles are themselves inactive o...
متن کاملMembrane Estrogen Receptor Engagement Activates Endothelial Nitric Oxide Synthase
17b-Estradiol (E2) is a rapid activator of endothelial nitric oxide synthase (eNOS). The product of this activation event, NO, is a fundamental determinant of cardiovascular homeostasis. We previously demonstrated that E2-stimulated endothelial NO release can occur without an increase in cytosolic Ca. Here we demonstrate for the first time, to our knowledge, that E2 rapidly induces phosphorylat...
متن کاملThe environmental estrogen, nonylphenol, activates the constitutive androstane receptor.
Nonylphenol (NP) and its parent compounds, the nonylphenol ethoxylates are some of the most prevalent chemicals found in U.S. waterways. NP is also resistant to biodegradation and is a known environmental estrogen, which makes NP a chemical of concern. Our data show that NP also activates the constitutive androstane receptor (CAR), an orphan nuclear receptor important in the induction of detoxi...
