Abstract

In the present study, we have analyzed effects of the endocrine distruptors, such as bisphenol A, nonylphenol and pentachlorophenol, on cell proliferation in the human breast cancer cell line, MCF-7, and the human prostate cancer cell line, PC-3, with MTT method. A dose dependent analysis of the cell proliferation of MCF-7 cells after administration of bisphenol A, nonylphenol and pentachlorophenol revealed a significant induction of cell proliferation. Maximum induction of cell proliferation was observed at concentrations between 10$\^$-7/ and 10$\^$-6/ M. Whereas, these chemicals had little effect on proliferation of PC-3 cells. These results demonstrated that bisphenol A, nonylphenol and pentachlorophenol do not induce proliferation of PC-3 cells but exhibit a significant induction of MCF-7 cell proliferation, suggesting all these chemicals are a estrogen mimic.

내분비계장애물질인 bisphenol A, nonylphenol, pentachlorophenol을 대상으로 여성 유방암세포 유래 MCF-7 세포주와 남성 전립선암세포 유래 PC-3 세포주에서 세포 증식효과를 MTT 방법으로 조사하였다. MCF-7 세포주에 이들 세 종류의 내분비계장애물질을 농도별로 처리하여 세포증식에 미치는 영향을 조사한 결과 모두 세포증식을 촉진하는 결과를 보였다. $10^{-7}$ M에서 $10^{-6}$ M 농도 범위에서 MCF-7 세포의 최대증식효과를 유도하였다. 그러나 PC-3 세포주의 경우에는 세포증식에 bisphenol A, nonylphenol, pentachlorophenol 모두 영향을 미치지 못하였다. 이러한 결과는 이들 세 종류의 내분비계 장애물질이 남성 전립선세포 유래인 PC-3 세포주의 증식에는 관여하지 않고 여성 유방암 세포에서 유래하고 에스트로젠 반응성인 MCF-7 세포주에만 증식효과를 갖는 사실을 보여주고 있으며 이는 bisphenol A, nonylphenol, pentachlorophenol이 여성호르몬인 에스트로젠과 유사한 역할을 한다는 사실을 보여주는 것이라 할 수 있다.
