Objective To investigate the effect of Wangzaozin A on the proliferation and apoptosis of human promyelocytic leukemia HL-60 cells. Methods HL-60 cells were treated with Wangzaozin A at different concentrations for different times. Trypan blue exclusion was performed to detect viability of HL-60 cells under an inverted microscope. Cell cycle arrest and apoptosis of HL-60 cells were detected by flow cytometry and AO/EB staining. DNA damage in HL-60 cells was d
etected by comet assay. Results Wangzaozin A strongly inhibited the growth of HL-60 cells at the concentration of 1-4 mol/L
and induced strong lethal effect to the cells at high concentrations (3 mol/L and 4 mol/L) for 48-72 h. Strong G
1
phase and S phase arrest could be induced by Wangzaozain A at 1-2.5 mol/L for 24 h or 48 h and at 4 mol/L for 12-60 h
respectively
and significant apoptosis of HL-60 cells was induced by Wangzaozain A at 2-4 mol/L (P0.01). At the same time
the DNA damage in the treatment group was significantly different from that of the control group (P0.05
P0.01). Conclusion Wangzaozin A induces proliferation suppression
cell cycle arrest and apoptosis in HL-60 cells directly through DNA damage.
