摘要
目的观察依马替尼(STI571)体外对干细胞受体阳性(c-Kit+)急性髓细胞白血病(AML)患者骨髓细胞凋亡的作用。方法用RT-PCR法检测c-Kit+AML细胞抑凋亡基因SurvivinmRNA和促凋亡基因SmacmRNA的表达水平。结果抑凋亡基因SurvivinmRNA的表达水平下降,促凋亡基因SmacmRNA的表达水平上升。结论STI571能诱导c-Kit+AML细胞促凋亡基因SmacmRNA上调,抑凋亡基因SurvivinmRNA的表达水平下降,发挥促凋亡作用。
Objective To investigate the influence about apoptosis of STI571 on expression of c-Kit in bone marrow cells from patients with acute myelogenous leukemia (AML). Methods RT-PCR was used to analyze the expression of survivin and smac mRNA on bone marrow cells from patients with AML after treatment with STI571. Results Survivin inhibits cell, apoptosis and smac induces cell apoptosis the expression of survivin mRNA decrease and smac mRNA increase. Conclusions STI571 induce apoptosis expression of c- Kit in bone marrow cells from patients with AML in a dose-dependent manner as well as a time-dependent msnner.
