SMAC exhibits anti-tumor effects in ECA109 cells by regulating expression of inhibitor of apoptosis protein family

Figure 3 Effects of LCL161 on apoptosis of ECA 109 cells. Serum-starved ECA109 cells were stimulated with LCL161 (5-20 mmol/L) for 24 h. A: The cell apoptosis was assayed by using TUNEL staining. Magnification × 40; B: Bar graphs showing mean percentage of DAPI-stained ECA109 nuclei that were TUNEL-positive following treatment with different concentrations of LCL161. ^cP < 0.001 vs control.
