Figure 3. Effect of B7-H1 knockdown on cell proliferation and apoptosis in HCT 116 cells.

Figure 3

(A) MTT analysis to detect cell proliferation. Parental or HCT116 cells were transfected with scrambled siRNA or siRNA targeting B7-H1 for 48 h were seeded in 96-well plates and cell proliferation was detected by MTT. Data were presented as means ± SD, *P<0.05 versus the si-scramble group. (B) Flow cytometric analysis to detect cell apoptosis. Parental or HCT116 cells transfected with scrambled siRNA or siRNA targeting B7-H1 for 48 h were collected and stained with Annexin-V-FITC and PI before flow cytometric analysis. Data were presented as means ± SD, *P<0.05 versus the si-scramble group.
