| Outline of Final Research Achievements |
The aim of this study is to construct an in vitro assay system to screen hazardous environmental chemicals that can transactivate the gene via Baikal seal estrogen receptors (bsERs). We constructed the in vitro reporter gene assay system where a expression vector containing bsERα or bsERβ cDNA and a reporter vector containing ER response element were introduced in COS-1 cells. Using this in vitro assay system, we screened the transactivation potencies of 26 bisphenol A and its analogues (BPs) and 16 hydroxylated polychlorinated biphenyl congeners (OH-PCBs). The results showed that most of the test chemicals were able to activate bsERα and bsERβ.
