Fig. 4

NB4 cells infected with a control lentivirus (NB4control), a MYBΔ3-encoding lentivirus (NB4MYBΔ3) or a C/EBPβ-encoding lentivirus (NB4C/EBPβ) were treated for 72 h with the indicated concentrations of AIB or HA. The cells were then stained with antibodies against CD11b (A) or with annexin V and propidium iodide (B) and analyzed by flow cytometry. Bars (A) indicate the percentage of CD11b positive cells (with standard deviations) of the viable cells. Asterisks indicate statistical significance (**p < 0.01, ***p < 0.001, Student’s t test). Bar charts (B) indicate the percentages (with standard deviations) of living (A-/PI-), early (A + /PI-) and late (A + /PI + ) apoptotic and necrotic (A-/PI + ) cells. The chemical structures of AIB and HA are shown in (A).
