Bisphenol A (BPA), is present in a multitude of products, including food and water containers, food can linings, dentistry sealants, and thermal paper. BPA can induce the growth of human ovarian cancer cell lines. Reduction of adhesion and the initiation of metastasis are important events in cancer progression; therefore, this study investigated the effects of BPA (0.1-100 nM) on the migration of OVCAR-3 ovarian cancer cells and the expression levels of metalloproteinases (MMPs) and cadherins. The oestrogenic compound 17 beta-estradiol (40 nM) was used as a positive control for estrogenic properties of bisphenol A. BPA stimulated cell migration, and the effect of BPA was similar to that of 17 beta-estradiol. BPA-induced cell migration was accompanied by up-regulation of the migration-related factors MMP-2, MMP-9 and Ncadherin, but E-cadherin expression and activity was unaffected. The stimulatory effects of BPA on cell migration were abolished by pre-treatment of the cells with inhibitors of the mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase pathways (PI3K). In conclusion, the results presented here show that BPA induces OVCAR-3 cells migration by activating MAPK and PI3K/ Akt signalling pathways.
