ABSTRACT
Objective To observe the estrogenic activity of octylphenol(OP) in vitro and to conduct a preliminary study of its mechanism. Methods The estrogenic activity of OP was detected by cell proliferation test of MCF 7 cells in vitro and the mechanism was preliminarily studied by growth curve analysis, cell cycle analysis, tamoxifen(Tam) antagonistic test and apoptosis detection. Results OP was found to have estrogenic activity to stimulate the proliferation of MCF 7 cells. Cell cycle analysis revealed that the cell proliferation indexes of OP and 17? estradiol(E 2) were higher than those of alcohol. The estrogenic activities of OP and E 2 to stimulate the proliferation of MCR 7 could be antagonized by Tam. Both OP and E 2 could inhibit the cell apoptosis of MCF 7 cells. Conclusion OP possesses estrogenic activity to stimulate the proliferation of MCF 7 cells. The mechanism may be due to binding to the estrogen receptor, which may have effect on cell proliferation and apoptosis.
