摘要: 目的 研究乙醇引起SK-N-SH成神经瘤细胞损伤的机制。方法 采用MTT法检测细胞死亡率。DNA片段分析法、DAPI核染色及caspase-3活性分析检测细胞凋亡。免疫印迹分析JNK和p38K的表达。结果 乙醇引起SK-N-SH细胞死亡率增加,该作用呈剂量依赖性。乙醇引起细胞发生凋亡样变化,表现为caspase-3激活、核DNA断裂及核碎裂。乙醇引起细胞死亡的机制部分与激活JNK和p38K通路有关。结论 乙醇通过激活JNK和p38K通路引起SK-N-SH成神经瘤细胞死亡。

Abstract: Objective To study the mechanism underlying the ethanol-induced damage to SK-N-SH neuroblastoma cells. Methods MTT reduction assay was used to evaluate the cell death rate induced by ethanol. DNA fragmentation analysis, DAPI nuclear staining, and caspase-3 activity assay were applied to examine the apoptotic alterations. Western blotting analysis was used to observe the expressions of JNK and p38K. Results Ethanol induced dose-dependent cell death in SK-N-SH cells, which was mediated via apoptosis, as indicated by increased caspase-3 activity, nuclear disruption, and DNA fragmentation. The ethanol-induced apoptosis was partially mediated by the activated JNK and p38K pathways. Conclusion Ethanol mediates cell death of SK-N-SH neuroblastoma cells by activation of JNK and p38K pathways.

Key words: ethanol, apoptosis, neuroblastoma cells
