Differences between estrogen- and antiestrogen-estrogen receptor complexes from human breast tumors identified with an antibody raised against the estrogen receptor.
Radiolabeled estrogens 17 beta-[3H]estradiol and diethylstilbestrol ( [3H]DES) and the antiestrogen [3H]monohydroxytamoxifen ( [3H]MHT) all bind with high affinity to the extranuclear estrogen receptor (ER) from the MCF-7 human breast tumor cell line (Kd = 3 X 10(-10), 2 X 10(-10), and 0.63 X 10(-10) M, respectively). A polyclonal antibody raised in a goat to the calf nuclear ER selectively dec...
متن کاملEstrogen and Antiestrogen Actions on Human Prostate Cancer: A Dissertation
Prostate cancer increases its incidence with age after men in their fifth decade as the ratio of estrogen to androgen rises. Epidemiological studies indicated that high levels of estrogens are associated with the high-risk ethnic groups for prostate cancer. Therefore estrogens may be involved in prostatic carcinogenesis. It is widely believed that the actions of estrogens are mediated by estrog...
متن کاملPowerful dominant negative mutants of the human estrogen receptor.
We have identified and characterized three human estrogen receptor (ER) mutants, which, at low concentrations, are capable of blocking the intracellular activity of wild type ER. The mutants, a truncated ER (ER1-530), a point mutant (L540Q), and a frameshift (S554fs), were generated by random chemical mutagenesis of the ER hormone binding domain and screened first for low activity in a yeast se...
متن کاملHuman Breast Tumorigenesis Altered Expression of Estrogen Receptor Coregulators during
The hypothesis that altered expression of specific coactivators/repressors of the estrogen receptor occurs during human breast tumorigenesis in vivo is examined in this study. Using in situ hybridization and reverse transcription-PCR assays, the expression of two coactivators (SRA and AIB1) and one repressor (REA) of the estrogen receptor was compared between matched breast tumors and adjacent ...
