摘要:

目的 探讨枸橼醛(citral)在急性早幼粒细胞白血病细胞系K562中的作用。方法 Citral作用于体外培养K562细胞系,分别用Wright-Giemsa染色观察细胞凋亡形态;MTT法计算细胞增殖能力;DNA电泳分析DNA碎片;Annexin V-FITC/PI分析细胞凋亡变化;RT-PCR法检测凋亡通路蛋白Bcl、Bax的表达水平变化;流式细胞术分析线粒体膜电位、Caspase-3和核因子(NF)-κB水平变化。 结果 Citral以时间和剂量依赖性方式诱导K562细胞凋亡,citral能够诱导线粒体膜电位减少。证实citral诱发细胞凋亡是依赖线粒体途径。 结论 Citral对白血病有潜在的治疗效果,有一定的临床应用前景。

Abstract:

Objective To investigate the effect of citral on the acute early young granulocyte leukemia cell line K562. Methods The apoptosis morphology was observed. Diffusion test, DNA electrophoresis, membrane proteins V-FITC/PI staining and Caspase activation in K562 cells were performed to evaluate the effect of citral on the role of K562. Results Citral induced the apoptosis of K562 cells in a time and dose dependent manner. Citral also induced the decreasing of mitochondrial membrane potential(MMP). Conclusion Citral has a potential effect in leukemia treatment and clinical application.
