Bcl-xl基因对硝普钠诱导SY5Y细胞凋亡的抑制作用
Inhibition Effect of Bcl-xl Gene on Apoptosis of SY5Y Cells Induced by Sodium Nitroprusside
摘要
Abstract
[Objective] To study the effect of Bcl-xl gene on cytotoxicity of SH-SY5Y cells induced by sodium nitroprusside. [Methods] The plasmid pIRES2-EGFP/Bcl-xl was transfected into SH-SY5Y cells. Three groups were designed: A) normal control group;B) pIRES2-EGFP control group; C) plRES2-EGFP/Bcl-xl group. After SH-SY5Y cells being treated with sodium nitroprusside (50 祄ol/L), the apoptosis was valued by Hoechst33258 stain. In addition, MTT was employed to test cell viability. We also did RT-PCR and Western blotting to investigate Bcl-xl gene expression. [Results] By transfection of pIRES2-EGFP/Bcl-xl, Bcl-xl gene could effectively express in SH-SY5Y cells. Supported by MTT results, Bcl-xl gene was able to partially reduce cell death induced by sodium nitroprusside. [Conclusion] Transfection of Bcl-xl gene can increase the expression of Bcl-xl and thus lead to weaken cell death induced by NO supplied by sodium nitroprusside. This result supports that cytotoxicity induced by SNP is mainly mediated via the process of apoptosis.关键词
