摘要: 肺纤维是一种高致死率的难治性疾病,TGF-β1可激活并上调NOX4 mRNA的表达,继而诱导机体产生大量ROS,而ROS可进一步激活Smad,参与介导TGF-β1/Smad信号通路,最终促使肺纤维化的发生。而通过各种技术手段阻断NOX4基因表达可干扰TGF-β1/Smad信号通路从而阻断肺纤维化,所以NOX4可能是肺纤维化进程中最具有前景的治疗靶点。

Abstract: Pulmonary fibrosis is a refractory disease with high mortality. The expression of NOX4 mRNA can be activated and increased by TGF-beta1 which could induce the production of a large number of ROS. ROS could further activate Smad which involved in mediating the signaling pathway of TGF-β1/Smad leading to the occurrence of pulmonary fibrosis. Blocking the expression of NOX4 gene through varieties of technologies would disturb the signaling pathway of TGF-β1/Smad which may block the progress of pulmonary fibrosis. Therefore NOX4 may be the most promising therapeutic target in the process of pulmonary fibrosis.
Key words: acute lung injury, NOX4, pulmonary fibrosis , ROS, TGF-β1
