摘要: 摘要:目的 探讨存活蛋白(Livin) 与白血病细胞耐药的关系,并探讨其在白血病多药耐药中的意义。方法 通过阿糖胞苷(Ara-C)药物浓度梯度递增法诱导建立白血病耐药细胞亚系THP-1R,然后将Livin siRNA转染至THP-1R,应用RT-PCR方法检测白血病细胞株THP-1和转染前后白血病耐药细胞株THP-1R中Livin mRNA的表达,Western blot 法检测Livin蛋白的表达,MTT法检测转染后THP-1R的耐药指数。结果 THP-1R中Livin的mRNA和蛋白表达水平明显高于THP-1 (P<0.05)。Livin siRNA转染后THP-1R耐药指数较未转染细胞明显降低(P<0.05);转染后THP-1R细胞Livin的mRNA和蛋白表达水平与未转染细胞比较两者差异具有显著性(P<0.05)。结论 Livin的高表达可能是人白血病细胞多药耐药形成的机制之一。

Abstract: Abstract: Objective To investigate the relationship between Livin and leukemia multi-drug resistance, and study its effect on leukemia multi-drug resistance. Methods The expressions of Livin in leukemia cell line THP-1 and leukemia multi-drug resistance cell line THP-1R were detected by RT-PCR and Western blot. The siRNA of Livin was transfected by RNAi-Mate into THP-1R, the expression of Livin was detected by RT-PCR and Western blot, The resistance index was detected by MTT. Results The expression of Livin in THP-1R was higher than that of THP-1 (P<0.05). After transfected with the siRNA of Livin, the resistance index was decreased significantly, and the expression of Livin was decreased compared with untransfected cells (P< 0.05). Conclusion The high-level expression of Livin may be one of the mechanisms of leukemia multi-drug resistance.
