LAMA3 and pulmonary fibrosis: Utilizing these identified genes, integrated proteomic analysis of IPF patients and bleomycin (BLM)‐induced pulmonary fibrosis in mice, we discovered that NPNT and lamininα3 (LAMA3) were the only genes consistently downregulated at both mRNA and protein levels in fibrotic lung tissues (Figure 1A,B; Figure S1A, Supporting Information).
