AZA inhibited viability of AML cells. AML cells U937 (A), THP-1 (B), KG-1 (C), NB4 (D) and HL-60 (E) were incubated with AZA and cell viability was then measured by the MTT assay. (F) The concentration of drug required to obtain 50% maximal inhibition in cell viability was indicated by IC50. The data are the means with standard deviations for three independent experiments. Compared with 24 h (ANOVA), ∗P < 0.05, ∗∗P < 0.01.
