(a) Cytotoxic effect of AraC, 5AC, DAC and Zeb on Kasumi-1 cells. Treatment-induced changes in cell size and granularity after treatment were assessed by measuring forward- and side-angle light scatter in a flow cytometer. The flow diagrams show one representative experiment (three replicates). (b) Inhibitory effect on proliferation. A total of 4 × 106 cells were seeded in each culture. The cell count after 72 h of treatment is shown. Error bars in both panels indicate one standard deviation (three replicate experiments).
