Purpose: Estrogen as a crucial hormone during pregnancy acts by two types of receptors. Estrogen receptor alpha, expressed by estrogen receptor 1 (ESR1) gene, is more abundant and exists in all human reproductive systems. Association of ESR1 gene polymorphism has been shown in some reproductive fields such as spontaneous abortion, endometriosis-related infertility and in vitro fertili...
We compared the Abbott enzyme immunoassay method for estrogen receptor with a standard dextran-coated charcoal method, and studied the effects of treatments causing denaturation. Estrogen receptor values were slightly higher by the Abbott method, but the methods agreed with regard to receptors being present or absent in 94-98% of 50 cases. Heat lability of immunoreactivity by the Abbott enzyme ...
PURPOSE To investigate the expression and distribution of estrogen receptor protein and mRNA in bovine and rat retinas. METHODS Western blot analysis with an antiestrogen receptor monoclonal antibody (mAb) was used to detect estrogen receptor protein in the bovine retina. Immunohistochemistry with an antiestrogen receptor mAb and in situ hybridization with an oligodeoxynucleotide sequence cod...
In an attempt to study the involvement of tyrosine kinase pathway in estrogen receptor signaling pathway, we used emodin, a tyrosine kinase inhibitor, to treat MCF-7 cells, a breast cancer cell line which express high level of estrogen receptor protein. Here we reported that emodin inhibited estrogen-induced expression of bcl-2 protein in MCF-7 breast cancer cells. Unexpectedly, treatment of th...
AIB1 was isolated as a gene amplified in breast cancer and encodes a protein that acts as a steroid receptor coactivator. The role of steroid receptor coactivators such as AIB1 in breast cancer development is not clear. It is possible that AIB1 cooperates with estrogen receptor alpha in regulating estrogen-dependent cell proliferation. Ectopic expression of the estrogen receptor alpha in differ...
PURPOSE Bladder symptoms can be ameliorated by sex steroids but to our knowledge the mechanism of action is unknown. Previous studies of steroid receptor expression in the bladder did not indicate receptor subtype expression. We report the distribution of estrogen and progesterone receptor isoforms in the female lower urinary tract. MATERIALS AND METHODS Prospectively recruited women undergoi...
