Effect of GLE on apoptosis in HCT116 cells. HCT116 cells were treated with cisplatin (5 µg/mL) and GLE (82, 106 and 136 µg/mL) for 24 h and 48 h, and the apoptotic rates were detected by Annexin V/PI double staining assay. Two-parameter (dual color fluorescence) dot plots (A and C) were obtained via flow cytometric analysis. Bar graphs (B and D) depict mean ± SD of three replicates. *P < 0.05 and **P < 0.01.
