左西孟旦通过PTEN/Akt通路抑制脂多糖引起的C2C12细胞凋亡
Levosimendan inhibits lipopolysaccharide-induced C2C12 cell apoptosis via the PTEN/Akt pathway
摘要
Abstract
Objective To investigate whether levosimendan can inhibit the apoptosis of C2C12 cells induced by lipopolysaccharide(LPS)through the PTEN/Akt pathway.Methods C2C12 cells were randomly divided into four groups:blank control group,control group comprising cells treated with levosimendan only,LPS-treated group,and a group comprising cells pretreated with levosimendan for 24 h a subsequently treated with LPS for 48 h.The survival rate of C2C12 cells was determined via the CCK-8 method,and cell apoptosis was assessed via Hoechst 33342 staining.The mRNA and protein expression levels of PTEN/Akt pathway components were evaluated via RT-qPCR and Western blotting,respectively.C2C12 cells were also transfected with siRNA to knockdown the PTEN gene,and the effect on the protein expression of apoptotic pathway components was determined.Results Levosimendan increased the survival rate and decreased the apoptosis rate of C2C12 cells after LPS treatment.PTEN gene expression was inhibited by siRNA and the mRNA and protein levels of PTEN/Akt signaling pathway components changed correspondingly.Furthermore,the apoptosis rate of C2C12 cells decreased.Conclusion Levosimendan can inhibit LPS-induced C2C12 cell apoptosis via the PTEN/Akt pathway.关键词
