Effect of RhoA gene silencing on proliferation and migration of gastric MGC-803 cells.

In this study, the expression of silencing RhoA gene in gastric MGC-803 Cells was investigated, in order to discuss the effect of RhoA gene on cell proliferation, cell cycles and tumor migration. SiRNA sequence of RhoA gene was designed and synthesized; MGC-803 cells were transfected by Lipofectamine(TM2000). The expression of RhoA gene in mRNA and protein after interference was detected by RT-PCR and Western blot; flow cytometry was used to detect the cell cycle; cell proliferation was detected by CCK-8 assay and cell migration was detected by scratch healing assay.
