摘要: Rationale: Idiopathic pulmonary fibrosis (IPF) is caused by alterations in expression of proteins involved multiple pathways, including matrix deposition, inflammation, injury, and repair.Objectives: To understand the pathogenic changes lung protein IPF to evaluate apolipoprotein (Apo) A-I as a candidate therapeutic molecule.Methods: Two-dimensional electrophoresis was adopted for differential display proteomics. Reverse-transcriptase polymerase chain reaction, Western blotting, immunohistochemical staining, ELISA were performed identification quantitative measurement Apo bronchoalveolar lavage fluids from subjects with experimental bleomycin-induced mice.Measurements Main Results: Sixteen spots showed differences relative intensity between (n = 14) healthy control 8). Nano liquid chromatography-tandem mass spectrometry (LC-MS/MS) revealed increase haptoglobulin decrease α1-antitrypsin, α1-antichymotrypsin...
