二烯丙基二硫诱导人白血病细胞系HL-60细胞分化的实验研究

目的　探讨二烯丙基二硫 (DADS)对人急性髓性白血病细胞系HL 6 0细胞增殖抑制及诱导分化作用的影响。方法　采用MTT法检测对细胞增殖的影响 ,通过观察细胞形态、硝基四氮唑蓝 (NBT)还原反应、流式细胞仪测定鉴定细胞分化。结果　HL 6 0细胞经DADS处理后 ,细胞增殖受抑 ,呈剂量效应关系。 0 6 2 5～ 1 2 5mg·L-1时NBT还原反应增强 (P <0 0 1或 <0 0 5 ) ,流式细胞术显示可诱导表面分化抗原CD11b表达升高及细胞周期阻滞于G1期。结论　小剂量DADS长时间作用对HL 6 0细胞具有诱导分化作用 ,其作用相当于全反式维甲酸 ,对于白血病的治疗具有潜在的应用价值

Experimental study of HL-60 cell differentiation induced by diallyl disulfide

AIM To investigate the proliferation inhibition and inducing differentiation effect of diallyl disulfide (DADS) on human acute myeloid cell line HL 60. METHODS Inhibition of HL 60 cell proliferation was shown by MTT assay; cell differentiation was determined by morphologic observation,the ability of NBT reduction activity and flow cytometric detection. RESULTS DADS has significant anti proliferative effect on HL 60 cells in a concentration dependent manner. The reduction ability of NBT and cell surface differentiation antigens CD11b had significantly increased( P <0 01 or <0 05), and cell cycle was arrested at G 1 stage with 0 625～1 25 mg·L -1 DADS. CONCLUSION Low dose DADS had the differentiation effect on HL 60 cells by long time treatment, as the effect of ATRA(all trans refinoic acid).
