摘要: BACKGROUND: An endocrine disruptor is a synthetic chemical, which causes adverse effects in an organism, or its progeny, after causing perturbations the system. It important to know chemicals have endocrine-disrupting action. However, increasing number of are being produced by modern chemistry, and examination potential has not yet caught up with advances chemistry. In this study, we developed such screening system for detecting estrogen-like effects. MATERIAL/METHODS: The was based on yeast one-hybrid Both HIS3 lacZ reporter genes connected three tandem copies estrogen response element were prepared. Gal4-estrogen receptor fusion protein made from activation domain (AD) GAL4 transactivator gene then incorporated into plasmid, transfected YM4271 cell strain. effect judged RESULTS: A dual assay-system established transfection both cells. This enabled detection as little 10-12 mol beta-estradiol. CONCLUSIONS: These results show that newly assay useful endocrine-disruptors
