目的,2,以lncRNA MALAT1为切入点,观察糖络宁对体外高糖诱导的大鼠雪旺细胞炎症反应的影响,探讨其保护雪旺细胞的可能机制。,方法,2,以大鼠雪旺细胞作为研究对象,采用高糖刺激构建细胞损伤模型,分为正常组(空白血清培养)、高糖组(150 mmol/L葡萄糖+空白血清培养)、糖络宁组(150 mmol/L葡萄糖+糖络宁含药血清培养)、MALAT1基因敲除组(150 mmol/L葡萄糖+ MALAT1抑制剂)4个组,48 h后,收集各组细胞并进行相关检测。以CCK-8法检测各组细胞活力,酶联免疫法检测各组细胞上清液中炎症因子(IL-6、MCP-1、TNF-α)的蛋白表达情况,实时荧光定量聚合酶链式反应检测各组细胞lncRNA MALAT1和炎症因子(IL-6、MCP-1、TNF-α)的表达情况。,结果,2,与正常组比较,高糖组细胞活力下降(,P,<,0.05),炎症因子(IL-6、MCP-1、TNF-α)的基因和蛋白表达均增加(,P,<,0.05),MALAT1表达水平明显升高(,P,<,0.05);而与高糖组相比,糖络宁组和MALAT1基因敲除组细胞活力有所升高(,P,<,0.05),各炎症因子的基因和蛋白表达均有所下调(,P,<,0.05),且糖络宁组MALAT1的表达水平较高糖组明显减少(,P,<,0.05)。,结论,2,糖络宁能减轻高糖诱导的大鼠雪旺细胞炎症反应,其部分机制是通过抑制lncRNA MALAT1的水平实现的。
Objective,2,To observe effects of Tangluoning on inflammatory reaction of Schwann cells induced by high glucose in vitro with lncRNA MALAT1 as the starting point and explore the possible mechanism of protecting Schwann cells.,Methods,2,With Schwann cells of rats as objective,cell injury model was established by high glucose stimulation. They were randomly divided into 4 group:normal group(blank serum culture),high glucose group (blank serum culture + 150 mmol/L glucose),Tangluoning group (medicine serum culture + 150 mmol/L glucose)and lncRNA MALAT1 knockout group(150 mmol/L glucose + MALAT1 inhibitor). The cells of each group were collected and detected after 48 hours. Cells viability was determined by CCK-8 assay. Expression of lncRNA MALAT1 and inflammatory factors (IL-6,MCP-1 and TNF-α)were assessed by real-time PCR or enzyme linked immunosorbent assay.,Results,2,Compared with the normal group,the cell viability of high glucose group was reduced (,P,<,0.05),the gene and protein expression of inflammatory factors (IL-6,MCP-1 and TNF-α) were increased (,P,<,0.05),the expression of MALAT1 was increased(,P,<,0.05);compared with high glucose group,the cell viability of both Tangluoning group and MALAT1 knockout group was increased(,P,<,0.05),the gene and protein expression of inflammatory factors were decreased (,P,<,0.05),the expression of MALAT1 of Tangluoning group was more decreased than that of the high glucose group (,P,<,0.05).,Conclusion,2,Tangluoning could alleviate inflammatory reaction of Schwann cell induced by high glucose through inhibiting the expression of lncRNA MALAT1.
