Our best articles related to Estrogen
In 1929 Adolf Butenandt and Edward Adelbert Doisy independently isolated and determined the structure of estrogen. Thereafter, the market for hormonal drug research opened up. The “first orally effective estrogen”, Emmenin, derived from the late-pregnancy urine of Canadian women,...
There are two different forms of the estrogen receptor, usually referred to as α and β, each encoded by a separate gene ( and , respectively). Hormone-activated estrogen receptors form dimers, and, since the two forms are coexpressed in many cell types, the receptors may form...

This gene encodes a member of the family of estrogen receptors and superfamily of nuclear receptor transcription factors. The gene product contains an N-terminal DNA binding domain and C-terminal ligand binding domain and is localized to the nucleus, cytoplasm, and ...

Estrogen receptor refers to a group of receptors that are activated by the hormone 17β-estradiol (estrogen). Two types of estrogen receptor exist: ER, which is a member of the nuclear hormone family of intracellular receptors, and the estrogen G protein-coupled ...

estrogen insensitivity syndrome (EIS) or estrogen resistance is a form of congenital estrogen deficiency caused by a defective estrogen receptor (ER). Thus, estrogens cannot be recognized and initiate their biological action. In humans, the condition is very rare and only ...
Some hair shampoos on the market include estrogens and placental extracts; others contain phytoestrogens. There are case reports of young children developing breasts after exposure to these shampoos. On September 9, 1993, the FDA determined that not all topically applied ...
Both ERs are widely expressed in different tissue types, however there are some notable differences in their expression patterns: * The ”ERα” is found in endometrium, breast cancer cells, ovarian stroma cells, and the hypothalamus. In males, ”ERα” protein is ...
Estrogens are produced primarily by developing follicles in the ovaries, the corpus luteum, and the placenta. Luteinizing hormone (LH) stimulates the production of estrogen in the ovaries. Some estrogens are also produced in smaller amounts by other tissues such as ...
Selective Estrogen Receptor Modulators (SERMs) are a class of compounds that act on the estrogen receptor. A characteristic that distinguishes these substances from pure receptor agonists and antagonists is that their action is different in various tissues, thereby granting the ...
Estrogen receptors were first identified by Elwood V. Jensen at the University of Chicago in the 1950s, for which Jensen was awarded the Lasker Award. The gene for a second estrogen receptor (ERβ) was identified in 1996 by Kuiper in ...
Aging Studies in female mice have shown that estrogen receptor-alpha declines in the pre-optic hypothalamus as they grow old. Female mice that were given a calorically restricted diet during the majority of their lives maintained higher levels of ERα in ...
ER-β is expressed by many tissues including blood monocytes and tissue macrophages, colonic and pulmonary epithelial cells and in prostatic epithelium and in malignant counterparts of these tissues. Also, ER-β is found throughout the brain at different concentrations in different ...Related Videos
