摘要 目的:观察过氧化物酶体增殖体激活受体-γ(PPAR-γ)激活对糖基化终末产物(AGEs)引起的大鼠肾系膜细胞细胞外基质积聚的影响.方法:体外培养正常大鼠肾系膜细胞,分别用糖化牛血清白蛋白(AGEs)及未经糖化的牛血清白蛋白(BSA)处理,检测不同浓度AGEs(0、12.5、25、50、100及200 mg·L-1)对肾系膜细胞条件培养基纤维连接蛋白(FN)、Ⅳ型胶原含量的影响及不同浓度罗格列酮(0、1.25、2.5、5及10 mmol·L-1)对AGEs(100 mg·L-1)引起的Ⅳ型胶原及FN积聚的影响.ELISA测定肾系膜细胞条件培养基中FN和Ⅳ型胶原蛋白含量,逆转录聚合酶链式反应(RT-PCR)检测系膜细胞PPAR-γmRNA的表达.结果:大鼠系膜细胞有PPAR-γ mRNA的表达;与相应浓度的BSA比较,AGEs(12.5~200 mg·L-1)可不同程度地刺激系膜细胞FN和Ⅳ型胶原的产生(P<0.01);给予PPAR-γ激活剂(1.25~10 mmol·L-1)可明显减轻AGEs(100 mg·L-1)引起的Ⅳ型胶原含量增加(P<0.01).结论:PPAR-γ激活可以明显减轻AGEs引起的Ⅳ型胶原积聚. Objective To investigate the role of peroxisome proliferator-activated receptor-γ (PPAR-γ) activation in rat mesangial cell extracellular matrix (ECM) accumulation induced by advanced glycation end products (AGEs). Methods Rat mesangial cells were treated with AGE-modified bovine serum albumin (AGEs) or native bovine serum albumin (BSA). The effects of AGEs (0, 12.5, 25, 50, 100 and 200 mg · L^-1) on mesangial cells fibronectin and collagen Ⅳ protein contents and the role of PPAR-γ activation in rat mesangial cells ECM accumulation induced by AGEs (100 mg · L^-1) were investigated. Fibronectin, collagen IV protein contents were detected by ELISA and PPAR-γ mRNA was analyzed by reverse transcriptase-polymerase chain reaction (RT- PCR). Results Mesangial cells expressed PPAR-γ mRNA. Compared with respective BSA groups, AGEs (12.5-200 mg·L^-1)increased fibronectin and collagen Ⅳ protein contents of rat mesangial ceils. PPAR-γ activation (1.25-10 mmol · L^-1) could ameliorate collagen IV protein increasing induced by AGEs (100 mg · L^-1) in mesangial cell medium. Conclusion PPAR-γ activation can ameliorate mesangial cells collagen Ⅳ increasing induced by AGEs.
