【摘要】：目的:觀察可溶性環(huán)氧化物水解酶抑制劑t-AUCB對TGF-β1誘導的人臍靜脈內(nèi)皮細胞(HUVEC)內(nèi)皮-間質轉化(End MT)的影響。方法:采用t-AUCB(50μmol/L)預處理HUVEC 40 min后,用TGF-β1(10μg/L)誘導HUVEC 24 h,采用Western blot法檢測Smad2/3的磷酸化水平;誘導72 h后,光鏡觀察細胞形態(tài)的變化,采用CCK-8試劑盒檢測細胞活性,采用實時熒光定量PCR檢測內(nèi)皮細胞標記物(CD31)、間質細胞標記物(collagenⅠ、collagenⅢ、vimentin)及End MT中重要的下游轉錄因子(snail1、twist1、twist2、ZEB1)mRNA的表達。同時設TGF-β1和tAUCB單獨作用組。結果:光鏡下,TGF-β1組細胞轉變?yōu)楠M長形,細胞間隙疏松,TGF-β1+t-AUCB組、t-AUCB組細胞形態(tài)正常。TGF-β1組細胞CD31 mRNA表達下調(diào),collagenⅠ、collagenⅢ、vimentin mRNA表達上調(diào),snail1、twist1、twist2、ZEB1 mRNA表達上調(diào),Smad2及Smad3蛋白磷酸化水平升高(P0.05)。與TGF-β1組比較,TGF-β1+t-AUCB組、t-AUCB組上述指標的表達均有一定程度的逆轉(P0.05)。結論:t-AUCB可通過抑制內(nèi)皮細胞的End MT而發(fā)揮抗纖維化作用。
[Abstract]:Aim: to observe the effect of t-AUCB, a soluble epoxide hydrolase inhibitor, on endothelium-mesenchymal transformation of human umbilical vein endothelial cells (HUVECs) induced by TGF- 尾 1. Methods: HUVEC was pretreated with t-AUCB50 渭 mol / L for 40 min. HUVEC was induced by TGF- 尾 1 10 渭 g / L for 24 h, and the phosphorylation level of Smad2/3 was detected by Western blot assay. After 72 h of induction, the changes of cell morphology were observed under light microscope, and the cell activity was detected by CCK-8 kit. Real time fluorescence quantitative PCR was used to detect the mRNA expression of endothelial cell marker CD31, interstitial cell marker collagen 鈪，
