Molecular mechanism of estrogen–estrogen receptor signaling
17β-Estradiol (E2), as the main circulating estrogen hormone, regulates many tissue and organ functions in physiology. The effects of E2 on cells are mediated by the transcription factors and estrogen receptor (ER)α and ERβ that are encoded by distinct genes. Localized at the peri-membrane, mitochondria, and the nucleus of cells that are dependent on estrogen target tissues, the ERs share simil...
متن کاملBlockade of Estrogen Action Upregulates Estrogen Receptor-α mRNA in the Fetal Brain
BACKGROUND Fetal neuroendocrine maturation in late gestation is critical for maintenance of fetal homeostasis, growth, and readiness for birth. Sheep express estrogen receptors (ERs) in various brain regions. However, little is known about the regulation of ER-alpha and ER-beta in the ovine brain prenatally. OBJECTIVE The present study was designed to test the hypothesis that the expression o...
متن کاملContributions of estrogen receptor-α and estrogen receptor-ß to the regulation of behavior.
Studies of the mechanisms by which estrogens influence brain function and behavior have advanced from the explication of individual hormone receptors, neural circuitry and individual gene expression. Now, we can report patterns of estrogen receptor subtype contributions to patterns of behavior. Moreover, new work demonstrates important contributions of nuclear receptor coactivator expression in...
متن کاملEstrogen-related Receptor β Reduces the Subnuclear Mobility of Estrogen Receptor α and Suppresses Estrogen-dependent Cellular Function.
Estrogen-related receptor (ERR) is a member of the nuclear receptor superfamily that has strong homology with estrogen receptor (ER) α. ERR has three subtypes (α, β, and γ) expressed in estrogen-sensitive organs, including ovary, breast, and brain. No endogenous ligands of ERRs have been identified, but these receptors share a common DNA element with ERα and control estrogen-mediated gene trans...
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...
