VX-680 significantly suppresses the proliferation in a number of leukemic cell types. OCI-AML3, NB4, HL-60 and ML-1 cells were incubated with increasing doses of VX-680 (1, 2, 5 and 10 nM) for 24 hr. Cell viability was measured by MTT assay. Data summarized three independent experiments, *p < 0.05, **p < 0.01, compared to control.
