摘要: 目的:探讨红参发酵产物(FRGE)对高糖刺激下大鼠肾小球系膜细胞(GMCs)增殖和细胞外基质(ECM)降解的影响,阐明FRGE对糖尿病肾病(DN)的防治作用及可能机制。方法:将GMCs分为正常对照(NG)组、高糖(HG)组、高糖+不同浓度(3.75、7.50和15.00 mg·L-1)FRGE组。四甲基偶氮唑盐(MTT)光吸收法观察各组GMCs的增殖率,酶联免疫吸附法(ELISA)检测培养细胞上清中Ⅳ型胶原蛋白(Col Ⅳ)的水平,蛋白免疫印迹技术(Western blotting)检测基质金属蛋白酶2(MMP-2)和基质金属蛋白酶组织抑制物2(TIMP-2)蛋白表达水平。结果:与NG组比较,HG组GMCs增殖率升高(P<0.01),Col Ⅳ水平升高(P<0.01),TIMP-2蛋白表达水平上调(P<0.01),MMP-2蛋白表达水平下调(P<0.01);与HG组比较,高糖+不同浓度FRGE组GMCs增殖率均降低(P<0.01),Col Ⅳ水平降低(P<0.01),TIMP-2蛋白表达水平下调(P<0.01),MMP-2蛋白表达水平上调(P<0.01)。结论:FRGE可通过抑制高糖诱导的大鼠GMCs增殖,促进ECM的降解,延缓DN的发生发展。

Abstract: Objective: To explore the influence of fermented red ginseng extract (FRGE) in the proliferation of rat glomerular mesangial cells (GMCs) and the degradation of extracellular matrix(ECM)under high sugar stimulation, and to clarify the prevention and treatment effects of FRGE on diabetic nephropathy ( DN) and the possible mechanism. Methods: The rat GMCs were cultured and divided into normal concentration of D-glucose (NG) group, high concentration of D-glucose (HG) group and high concentration of D-glucose plus different concentrations (3.75, 7.50, 15.00 mg·L-1) of FRGE groups. The proliferation rates of rat GMCs were detected with MTT,and the type Ⅳcollagen(Col Ⅳ) levels in supernatants of the GMCs were detected by ELISA. The protein expressions levels of matrix metalloproteinase-2(MMP-2) and tissue inhibitor of metalloproteinase-2 (TIMP-2) were detected with Western blotting method. Results: Compared with NG group, the proliferation rate of GMCs in HG group was increased(P<0.01), the Col Ⅳ level was increased(P<0.01),the MMP-2 expression level was decreased, and the TIMP-2 expression level was up-regulated(P<0.01). Compared with HG group, the proliferation rates of GMCs in various FRGE groups were decreased(P<0.01), the Col Ⅳ levels were decreased(P<0.01),the expression levels of TIMP-2 were reduced(P<0.01),and the expression levels of MMP-2 were increased(P<0.01). Conclusion: FRGE can inhibit the proliferation of rat GMCs induced by high sugar and promote the ECM degradation to delay the occurrence and development of DN.
