Figure 7. RAI2 knockdown promoted the growth, cell migration, and invasion in GC cells. (A) The knockdown efficiency of RAI2 in GC cell line MGC803 using siRNA. (B) The AlamarBlue assay of cell proliferation in MGC803 cells transfected with siRNA NC or RAI2 siRNA. (C–F) The Transwell cell migration and invasion abilities were assessed in MGC803 cells using RAI2 siRNA. **P < 0.01, *P < 0.05.
