tamoxifen aziridine

01/01/1996 - "Tamoxifen aziridine labeling of the estrogen receptor-potential utility in detecting biologically aggressive breast tumors."
08/20/1990 - "MCF-7 human breast cancer cells were submitted to the tritiated antiestrogen tamoxifen aziridine, frozen at -170 degrees C, stored and irradiated at -78 degrees C in a calibrated Gammacell 60Co irradiator. "
11/01/1995 - "Recent investigation from our laboratory revealed that the estrogen receptor (ER) from breast cancer is characterized by a high molecular weight polymorphism: SDS-polyacrylamide gel electrophoresis of [3H]-tamoxifen aziridine ([3H]-TAZ) labeled cytosols usually display several bands corresponding to the native receptor (67 KDa) and lower molecular cleavage products. "
11/06/1991 - "Comparison of tritiated estradiol and tamoxifen aziridine for measurement of estrogen receptors in human breast cancer cytosols."
10/01/1989 - "The denatured and nondenatured forms of the estrogen receptor (ER) in MCF-7 human breast cancer cells have been characterized by gel electrophoresis using the covalently attaching ligand [3H]tamoxifen aziridine ([3H]TA). "

11/06/1991 - "We failed to identify a specific [3H]tamoxifen aziridine electrophoretic pattern with respect to the tumor estrogen receptor content as measured by the dextran-coated charcoal assay. "
11/06/1991 - "It will be clinically important to see whether the tumors positive for [3H]tamoxifen aziridine only correspond to the small subset of tumors (10%) which respond to tamoxifen treatment despite very low estrogen receptor levels, as measured by the dextran-coated charcoal technique."
12/01/1985 - "The effect of tamoxifen aziridine and tamoxifen (Tam), the parent compound which is an antiestrogen that binds reversibly to the estrogen receptor, were compared with respect to their effects on uterine growth, growth of dimethylbenzanthracene (DMBA)-induced mammary tumors in rats, and proliferation and plasminogen activator activity of MCF-7 human breast cancer cells. "

06/01/1991 - "Using sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blotting techniques, enriched preparations of the natural anti-ER IgG subpopulation (IgGs) were found to specifically immunoprecipitate ER extracted from MCF-7 mammary carcinoma cells and to compete with [3H]tamoxifen-aziridine for ER binding.
