摘要: 目的 研究牛磺熊去氧胆酸(TUDCA)对肺纤维化防治作用。 方法 建立转化生长因子-β1(TGF-β1)诱导的人胚肺成纤维细胞(MRC-5)肺纤维化细胞模型。用MTS法测定TUDCA的安全实验剂量后,用实时定量-PCR和Western blot检测α-平滑肌动蛋白(α-SMA)和纤连蛋白的mRNA和蛋白表达。 结果 1)TUDCA对MRC-5细胞无明显细胞毒作用。2)TUDCA 显著缓解TGF-β1诱导的α-SMA和纤连蛋白的表达。结论 TUDCA可以缓解TGF-β1诱导的肺纤维化表型。

Abstract: Objective To investigate the prophylactic and therapeutic effects of tauroursodeoxycholic acid (TUDCA) on transforming growth factor-β1 (TGF- β1)-induced fibrosis in MRC-5 cells. Methods Establish TGF-β1-induced MRC-5 pulmonary fibrosis model. Determine cytotoxicity of TUDCA on MRC-5 cells by MTS. Real-time PCR and Western Blot were applied to quantify the expression of fibrosis biomarker α-SMA and fibronectin. Results 1) TUDCA was well tolerated by MRC-5 cells. 2) TUDCA was able to significantly alleviate the expression of α-SMA and fibronectin induced by TGF-β1 in MRC-5 cells. Conclusion TUDCA alleviates TGF-β1-induced pulmonary fibrotic phenotype in MRC-5 cells.

Key words: tauroursodeoxycholic acid, pulmonary fibrosis, TGF-β1
