After functional protein-protein interaction network analysis using String (https://cn.string-db.org/) and Cytoscape, we revealed a TGF-β1-centered interaction network involving the “superoxide anion generation” and “assembly of collagen fibrils and other multimeric structures” pathways within the framework of bleomycin-induced lung fibrosis (Figure 1E). This evidence concerns the gene TGFB1 and pulmonary fibrosis.
