摘要: 目的: 通过观察阿魏酸对高糖诱导的肾小球系膜细胞炎症及自噬水平的影响,探讨阿魏酸对糖尿病肾病的保护作用及其可能机制。方法: 将SV40 MES 13细胞进行传代培养,随机分为:正常组(Control,5.6 mmol/L 葡萄糖)、甘露醇组(Man,30 mmol/L 甘露醇)、高糖组(HG,30 mmol/L 葡萄糖)、阿魏酸组(FA,30 mmol/L 葡萄糖 + 12.5、25、50、100、200 μmol/L 阿魏酸)。采用MTT法观察各组系膜细胞增殖情况;酶联免疫吸附试验(ELISA)法检测细胞上清液肿瘤坏死因子-α(TNF-α)、单核细胞趋化蛋白-1(MCP-1)和白介素-1β(IL-1β)的含量;免疫印迹法(Western blot)检测系膜细胞NLRP3、IL-1β、LC3-Ⅱ/Ⅰ、p62蛋白的表达水平。结果: ①与Control组相比,HG组肾小球系膜细胞增殖活力显著升高(P<0.01),与HG组相比,不同浓度FA组的肾小球系膜细胞增殖活力则有不同程度的下降(P<0.05~0.01);②与Control组相比,HG组细胞上清液中TNF-α、MCP-1和IL-1β含量均显著增加(P<0.01),与HG组相比,FA组TNF-α、MCP-1和IL-1β含量均显著减少(P<0.01);③与Control组相比,HG组细胞LC3-Ⅱ/Ⅰ比值减小,p62、NLRP3和IL-1β蛋白表达则均显著升高(P<0.01),与HG组比较,FA组细胞LC3-Ⅱ/Ⅰ比值明显增大(P<0.05),p62、NLRP3和IL-1β蛋白水平均显著降低(P<0.01)。结论: FA可抑制高糖诱导的SV40 MES 13细胞异常增殖,FA可通过抑制炎症、提高自噬水平而保护系膜细胞。

Abstract: Objective: To investigate the protective effects and possible mechanisms of ferulic acid on diabetic nephropathy by observing the effects of ferulic acid on the level of inflammation and autophagy in glomerular mesangial cells induced by high glucose. Methods: SV40 MES 13 cells were cultured and randomly divided into the following groups: normal group (Control, 5.6 mmol/L glucose), mannitol group (Man, 30 mmol/L mannitol), high glucose group (HG, 30 mmol/L glucose), ferulic acid group (FA, 30 mmol/L glucose + 12.5, 25, 50, 100, 200 μmol/L ferulic acid), and the proliferation of SV40 MES 13 cells in each group was observed by MTT method. The levels of tumour necrosis factor-α (TNF-α), monocyte chemotactic protein-1 (MCP-1) and interleukin 1β(IL-1β)in cell supernatant were determined by enzyme-linked immunosorbent assay (ELISA). The expressions of NLRP3, IL-1β, LC3-II/I and p62 proteins in SV40 MES 13 cells were detected by Western blot. Results: ①The proliferative activity of SV40 MES 13 cells was significantly higher in the HG group compared to the control group (P<0.01), while the proliferative activity of SV40 MES 13 cells was decreased to different degrees in the FA group compared to the HG group (P<0.05~0.01). ②Compared to the control group, the levels of TNF-α, MCP-1 and IL-1β were increased significantly in the cell supernatant of HG group (P<0.01). Compared with the HG group, the levels of TNF-α, MCP-1 and IL-1β were decreased significantly in the FA group (P<0.01). ③Compared with the control group, LC3-II/Ⅰ protein expression was decreased in the HG group, while the levels of p62, NLRP3 and IL-1β protein were increased significantly (P<0.01). Compared with the HG group, the expression of LC3-II/Ⅰ protein was elevated significantly (P<0.05) in the FA group, while the levels of p62, NLRP3 and IL-1β protein in the FA group were decreased significantly (P< 0.01). Conclusion: FA can inhibit the abnormal proliferation of SV40 MES 13 cells induced by high glucose. FA can protect glomerular mesangial cells by inhibiting inflammation and increasing the level of autophagy.
