摘要: 目的 研究二氯乙酸钠(dichloroacetate,DCA)对氧糖剥夺(oxygen glucose deprivation,OGD)损伤模型中小鼠小胶质细胞(BV2细胞)的保护作用,并探讨其作用机制。 方法 将BV2细胞分为3组:对照组、OGD组、DCA治疗组,通过OGD 4 h建立损伤模型。CCK-8和流式细胞仪检测细胞凋亡及ROS和NO的表达,Western blot检测NF-κB通路相关蛋白表达水平。 结果 CCK-8及流式细胞检测结果表明,DCA可显著降低OGD诱导的BV2细胞凋亡,并且减少OGD后细胞中活性氧(ROS)和一氧化氮(NO)的表达(P<0.05)。Western blot结果显示,DCA可显著影响OGD损伤介导的BV2细胞JNK、I-κB和NF-κB蛋白表达水平(P<0.05)。 结论 DCA对OGD损伤的BV2细胞具有保护作用,其机制与抗凋亡、抗氧化和抗炎作用有关。Abstract: Objective To study the protective effect and mechanism of dichloroacetate (DCA) on BV2 microglia in oxygen glucose deprivation (OGD) injury model. Methods BV2 cells were divided into 3 groups:CON group,OGD group and DCA intervention group.The injury model was established by OGD 4 h.CCK-8 and flow cytometry was used to detect apoptosis and expression of ROS and NO in cells.Western blot was used to detect the expression of proteins related to NF-κB pathway. Results CCK-8 and flow cytometry showed that the apoptosis of BV2 cells induced by OGD and the expression of ROS and NO in OGD cells were decreased significantly by DCA (P<0.05).Western blot analysis showed that the expression of I-κB,JNK and NF-κB protein in BV2 cells mediated by OGD injury were influenced significantly by DCA (P<0.05). Conclusion DCA had a protective effect on OGD-injured BV2 cells through anti-oxidation and anti-apoptosis.
