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

Figure 2 Change of Livin expression after small interfering RNA transfection. This figure shows Livin expression (%) in HCT116 cells at 18, 24 and 30 h post-transfection with 25, 50, 100, 150 and 200 μmol/L of siRNA. Livin expression was compared with β-actin by Western blotting. A: Livin expression at 18 h post-transfection. It was effectively suppressed by 25 μmol/L of siRNA, but this suppression was not dose-dependent; B: Livin expression at 24 h post-transfection; C: Livin expression at 30 h post-transfection; It was retrieved 30 h after transfection.
