Aim To study the effects of cycle arrest and molecular mechanism in human leukemia HL-60 cells induced by diallyl disulfide( DADS). Methods Cell count,colony formation in soft agar experiments and flow cytometry analysis were employed to observe the DADS-induced cell growth inhibition and the effect of cycle arrest in HL-60 cells. The expressions of Chk1 /2 and its downstream element in HL-60 cells were detected by Western blot. Results Cell count revealed that population doubling time increased to35. 03 h ...
