Figures & data

Figure 1. Proliferation is suppressed and apoptosis is induced by AZD3759 in glioma cells. a. The clonogenic assay used to determine the proliferation ability of cells. b. The apoptotic rate of treated glioma cells detected by flow cytometry. The Q2 + Q3 flow cytometry gates are used for the calculation of apoptotic rate. c. The cell cycle of treated glioma cells detected by flow cytometry (*p < 0.05 vs. control, **p < 0.01 vs. control, #p < 0.05 vs. 4 μM AZD3759)
