【摘要】Objective: To investigate the effect of silencing CD105 and Ki67 gene expression on OVCAR3 cell line in ovarian cancer. Methods: According to cell transfection results, OVCAR3 cells were divided into CD105-siRNA, Ki67-siRNA, CD105-siRNA+ Ki67-siRNA, negative control (NC1 and NC2) and control (non-transfection) groups. The effect of silencing CD105, Ki67 and their combined gene on proliferation, migration, invasion and apoptosis of human ovarian cancer cells can be studied and analyzed with MTT assay, wound-healing assay, Transwell chamber and flow cytometry. Results: Compared with their respective negative control and liposome control groups, proliferation, migration and invasion abilities of OVCAR3 cells were decreased obviously in CD105-siRNA, Ki67-siRNA and CD105-siRNA + Ki67-siRNA groups after gene silencing. Whereas, the most significant change was detected in CD105-siRNA + Ki67-siRNA group along with obviously increased apoptosis rate of cancer cells, and the differences were of statistical significance (p < .01, p < .05). Conclusions: Expression vectors of
