Figure 3.

Effect of low-dose aspirin and MAPK inhibitors on the apoptosis of PC-9 cells. (A) Flow cytometric analysis of PC-9 human lung cancer cells incubated with aspirin and MAPK inhibitors for 24 h. The right bottom quadrant represents Annexin V-stained cells (early-phase apoptotic cells). The top right quadrant represents PI and Annexin V-stained cells (late-phase apoptotic cells). (B) Quantitative results of the aspirin group in (A) and in the absence of MAPK inhibitors. (C) Quantitative results of cell apoptosis in (A). (n=3, mean ± standard deviation; ^*P<0.05 and ^**P<0.01 vs. control cells).
