Impact and mechanism study of dioscin on biological characteristics of colorectal cancer cells

Figure 2 Effect of dioscin on HCT116 cell apoptosis. A: Annexin V-FITC and PI staining was utilized to assess apoptosis in various concentrations (0, 1.25, 2.5 and 5 μg/mL) of dioscin-treated HCT116 cells after 48 hours by using flow cytometry; B: Quantification of apoptosis in HCT116 cells. Three biological repeats were reported as mean ± SD. ^aP < 0.01, ^bP < 0.001 compare to the control group.
