Twenty genes with the highest scores (IL6, VEGFA, IGF1, SPP1, CDH5, WNT3A, PROM1, SOX2, ICAM1, EDN1, MMP1, COL1A1, MMP7, CSF3, CAV1, POSTN, COL3A1, COMP, LCN2, and HBEGF) were identified as hub genes (Figure 6B), suggesting that these genes play roles in the occurrence and development of IPF. Here, SOX2 is linked to idiopathic pulmonary fibrosis.
