摘    要:目的:探讨三氧化二砷(Arsenic trioxide,ATO)对甲磺酸伊马替尼(STI571)在慢性粒细胞白血病(CML)原代细胞中对细胞增殖及凋亡的影响。方法:采用四甲基偶氮唑蓝(MTT)法观察STI571单独使用与联用ATO对慢性粒细胞白血病原代细胞增殖抑制的变化情况。流式细胞仪检测细胞凋亡。结果:无毒剂量的ATO(0.15μmol·L-1)联用STI571(IC500.324±0.011μmol·L-1)较单独使用STI571(0.580±0.007μmol·L-1)时对细胞抑制率显著增大,IC50下降1.79倍(P〈0.05)。细胞经ATO(0.15μmol·L-1)、STI571(0.5μmol·L-1)联合处理24h、48h时,细胞凋亡率增大为15.6%、50.7%,协同作用为增强(++)。结论:ATO能增强STI571对CML原代细胞敏感性,能促进细胞凋亡与STI571具有增强的协同作用。

Abstract:OBJECTIVE:To study the synergistic effect ofarsenic trioxide(ATO) and STI571 on proliferation and apoptosis of primary cells in patients with chronic myeloid leukemia(CML).METHODS:The proliferation of primary cells treated with STI571 alone or in combination of ATO was analyzed by MTT assay,and apoptosis was measured by flow cytometry.RESULTS:As compared with STI571(0.580 ± 0.007 μmol·L-1) alone,addition of nontoxic dose of ATO(0.15 μmol·L-1) to STI571(IC500.324 ± 0.011 μmol·L-1) showed remarkably higher cell inhibition ratio and lower IC50(down 1.79 times,P 0.05).After treatment with ATO(0.15 μmol·L-1) in combination with STI571(0.5 μmol·L-1) for 24 and 48 hours,the apoptotic rate increased to 15.6% and 50.7%,respectively,showing a synergistic effect(+ +) of the two drugs.CONCLUSION:ATO can enhance the sensitivity of primary cells of CML to STI571 and promote apoptosis,suggesting thesynergistic effect of ATO and STI571.
