罗格列酮对多囊肾囊肿衬里上皮细胞p38促分裂原活化蛋白激酶信号通路的影响

Objective To investigate the effect of rosiglitazone on p38 mitogen-activated protein kinase (p38MAPK) pathway in polycystic kidney cyst-lining epithelial cells. Methods The cyst-lining epithelial cells (PKD cells) from human polycystic kidney were treated with rosiglitazone (10 μmol/L), peroxisome proliferator-activated receptor-γ (PPARγ) inhibitor GW9662 (10 μmol/L), rosiglitazone (10 μmol/L) +GW9662 (10 μmol/L), p38MAPK specific inhibitor SB203580 (10 μmol/L), SB203580 (10 μmol/L)+ rosiglitazone(10 μmol/L) for 2 hours followed by epidermal growth factor (EGF) stimulation. Protein expressions of p38, phuspho-p38 (p-p38) and proliferating cell nuclear antigen (PCNA) were detected by Western blot. p38 mRNA was examined by RT-PCR. Expression of c-fos and c-jun was observed by immunocytochemistry. Results (1) EGF markedly up-regulated the expressions of p38, p-p38, PCNA, c-fos anti c-jun compared with control group (P<0.01). (2) Compared with EGF treated group, rosiglitazone significantly reduced p38 activation and mRNA expression (P<0.01, respectively). Rosiglitazone, rosiglitazone+SB203580 could significantly down-regulated p-p38, PCNA, c-fos and c-jun expression (P<0.01, respectively) with no significant difference between these two groups. (3) GW9662 partially reversed the reduction effect of rosiglitazone. Conclusions Rosiglitazone can inhibit proliferation of autosomal dominant polycystic kidney disease cyst-lining epithelial cells partially through down-regulating p38 activation and reducing c-fos, c-jun and PCNA expression. The above effect of rosiglitazone is in part PPARγ-independcnt.

syndecan-4对碱性成纤维细胞生长因子诱导人肾小球系膜细胞增殖及细胞外基质分泌的影响

目的 研究syndecan-4对碱性成纤维细胞生长因子（bFGF）诱导人肾小球系膜细胞(HMC)增殖及细胞外基质（ECM）分泌的影响,并探讨syndecan-4-蛋白激酶Cα（PKCα）途径在其中的作用。 方法 免疫荧光方法观察syndecan-4在HMC上的表达。筛选有效的syndecan-4-siRNA转染HMC,噻唑蓝（MTT）比色法检测HMC在bFGF不同作用时间下的增殖差异;ELISA法检测细胞上清液中的Ⅰ、Ⅳ型胶原和纤连蛋白（FN）含量;荧光定量PCR观察syndecan-4和PKCα含量的变化。 结果　syndecan-4蛋白在HMC有表达。bFGF可促进HMC的增殖及FN、Ⅳ型胶原的分泌,使得每百万看家基因中PKCα拷贝数明显增加。转染syndecan-4 siRNA后,显著降低了HMC的增殖速度（48~60 h时点,P < 0.01）、ECM分泌（FN：24 h时点,P < 0.01,48~96 h,P < 0.05;Ⅳ型胶原：72~96 h时点,P < 0.05）及PKCα含量 （0 h时点,P < 0.05,12 ~48 h时点,P < 0.01）。 结论 syndecan-4参与调控bFGF诱导HMC的增殖及ECM分泌过程。syndecan-4-PKCα途径可能在其中扮演重要作用。
