摘　　要：探讨楝酰胺对急性髓系白血病(acute myeloid leukemia,AML)细胞线粒体的作用。MTT法测定楝酰胺对AML细胞HEL生长增殖的影响,PI法测定细胞周期的变化。流式细胞技术分析楝酰胺对细胞凋亡率的影响,Western blot检测线粒体凋亡途径相关蛋白的变化,钙黄绿素法分析楝酰胺对线粒体通透性转换孔(mitochondrial permeability transition pore,mPTP)的影响,JC-1染料检测线粒体膜电位的变化,荧光素酶实验测定三磷酸腺苷(adenosine triphosphate,ATP)水平。结果显示楝酰胺抑制HEL细胞的生长增殖并呈现时间和浓度依赖性,阻滞细胞周期于G0/G1期。楝酰胺诱导HEL细胞线粒体途径凋亡,激活HEL细胞mPTP的开放,降低了线粒体膜电位和ATP水平。以上结果说明,楝酰胺改变了HEL细胞的线粒体功能,从而抑制细胞增殖。This study aims to explore the effect of rocaglamide on mitochondria function in acute myeloid leukemia(AML)cell line HEL.MTT assay was used to determine the effect of rocaglamide on the proliferation of HEL cells.Cell cycle was analyzed by PI staining.Flow cytometry was used to detect the apoptotic rate of HEL cells.Western blot was used to detect mitochondrial apoptosis pathway related protein.The effect of rocaglamide on mitochondrial membrane permeability was analyzed by calcein method.JC-1 dye was used to detect the changes in mitochondrial membrane potential.Luciferase experiment was used to determine the effect of rocaglamide on adenosine triphosphate(ATP)level.The results showed that rocaglamide inhibited the proliferation of HEL cells in a time-and concentration-dependent manner and arrested cell cycle of HEL cells at G0/G1 phase.Rocaglamide induced mitochondrial pathway apoptosis,activated the opening of the mitochondrial permeability transition pore(mPTP),and reduced the mitochondrial membrane potential of HEL cells as well as the ATP level.The above results indicated that rocaglamide remodeled the mitochondrial function of HEL cells,thereby inhibiting the proliferation of AML cells.
