siRNA targeting Livin decreases tumor in a xenograft model for colon cancer

Figure 5 Results of Annexin V staining after small interfering RNA transfection in HCT116 cell line. The apoptotic portion (right lower quadrant) was increased continuously after siRNA transfection, but the necrotic portion (right upper quadrant) was also increased. A: The apoptotic rate of staining was 0.26%; B: The apoptotic rate of control was 3.91%; C: The apoptotic rate of cells transfected with siRNA 50 μmol/L was 30.32%; D: The apoptotic rate of cells transfected with siRNA 100 μmol/L was 32.88%; E: The apoptotic rate of cells transfected with siRNA 150 μmol/L was 36.91%; F: The apoptotic rate of cells transfected with siRNA 200 μmol/L was 45.08%.
