Figure 3. Active caspase-3 analysis in HCE-2 cells. Columns represent the proportion of caspase-3 from positive control which was set to be 100% (mean±SD). One-Way ANOVA, followed by Dunnett’s post hoc test, evaluated the statistical differences (n=6, *0.01<p≤0.05, **0.001<p≤0.01, ***p≤0.001, ns=not significant). Experiments were repeated three times.
