Abstract	In the present study, we investigated the in vitro antitumor functions of a synthetic chalcone derivative 4,3′,4′,5′- tetramethoxychalcone (TMOC) in ovarian cancer cells. We found that TMOC inhibited the proliferation and colony formation of cisplatin sensitive cell line A2780 and resistant cell line A2780/CDDP, as well as ovarian cancer cell line SKOV3 in a time- and dose-dependent manner. Treatment of A2780 cells with TMOC resulted in G0/G1 cell cycle arrest through the down-regulation of cyclin D1 and CDK4, and the up-regulation of p16, p21 and p27 proteins. We demonstrated that TMOC might induce cell apoptosis through suppressing Bcl-2 and Bcl-xL, but enhancing the expression of Bax and the cleavage of PARP-1. Treatment of TMOC also reduced the invasion and migration of A2780 cells. Finally, we found that TMOC inhibited the constitutive activation of STAT3 signaling pathway and induced the expression of the tumor suppressor PTEN regardless of the p53 status in cell lines. These data suggest that TMOC may be developed as a potential chemotherapeutic agent to effectively treat certain cancers including ovarian cancer.
