Pseudolaric Acid B Induces Caspase-Dependent and Caspase-Independent Apoptosis in U87 Glioblastoma Cells

Figure 4

Flow cytometry analysis of apoptosis in U87 glioblastoma cells. (a) U87 cells were treated with indicated concentrations of PLAB in the presence or absence of z-VAD-fmk (20 μM) or PFT (20 μM) for 24 h. After staining with Annexin V/PI, samples were analyzed by flow cytometry for apoptosis rates. (b) Data are expressed as Mean ± SEM ( ). Columns not sharing the same superscript letter differ significantly ( ).
