Gastric cancer is one of the most common cancers in the world; taxol displayed modest efficacy as first-line chemotherapy for gastric cancer, conversely, it has limitations used alone. β-catenin is a multifunctional oncogenic protein and the elevation in expression and activity of β-catenin has been implicated in many cancers. Therefore, we assume that the inhibition of β-catenin can enhanced the efficacy of taxol. The purpose of this study was to investigate the inhibitory effect of miR-200a mimics, FH535 combined with taxol on proliferation and invasion of human gastric cancer cell lines SGC-7901 and BGC-823. In the current study, we identified that the combination of FH535 and miR-200a with taxol had potent growth-inhibitory and pro-apoptotic effects. Further, similar results were also observed in vivo, intratumoral injection of FH535, taxol and miR-200a mimics which also delayed tumor growth in nude mice harboring subcutaneous SGC-7901 xenografts. Collectively, miR-200a and FH535 can enhance the inhibitory effect of taxol on cell proliferation and moderate the invasion of human gastric cancer.
