摘要
目的:研究小檗碱对金黄色葡萄球菌(S.aureus)诱导ECV-304细胞内凋亡相关基因Bcl-2、Bax和Caspase-3表达的调节作用。方法:小檗碱(Berberine,BBR)预处理ECV-304细胞2h后,用S.aureus感染细胞,采用半定量RT-PCR及Western-blot法检测金黄色葡萄球菌感染后ECV-304细胞内Bcl-2、Bax和Caspase-3的mRNA及蛋白表达水平。结果:小檗碱预处理ECV-304后再感染S.aureus可显著性增加凋亡相关细胞因子Bcl-2mRNA水平及蛋白表达量,而Bax和Caspase-3表达下调。结论:小檗碱可以调节S.aureus诱导的ECV-304细胞内凋亡相关基因的表达,抑制ECV-304细胞凋亡。
Objective:To study the protection of berberine against ECV- 304 apoptosis induced by Staphylococcus aureus(S.aureus) via regulating Bcl-2,Bax and caspase-3 expression.Methods:ECV-304 were pretreated with 128μg/m LBBR for 2h,then Saureus was added.The expression levels of apoptosis related genes were detected with semi-quantityRT- PCR and Western- blot.Results:Pretreatment of BBR helped to survive in Saureus- induced ECV- 304.BBR significantly increased the expression levels of Bcl-2 and decreased that of Bax and Caspase-3 after staphylococcus aureus infection.Conclusion:Berberine can regulate the expression of apoptosis related genes of ECV-304 cells induced by S.aureus.
