Yu et al. explored six hub genes (COL3A1, COL1A2, OGN, COL15A1, ASPN, MXRA5) and sevenhub miRNAs(hsa-let-7b-5p, hsa-miR-26a5p, hsa-miR-25-3p, hsa-miR-29c-3p, hsa-let-7c-5p, hsa-miR-29b3p, and hsa-miR-26b-5p) that were closely associated with IPF and NSCLC (Yu et al., 2020). Here, COL15A1 is linked to idiopathic pulmonary fibrosis.
