Ingenuity Pathway Analysis showed these significant miRNAs to be associated with several features, some of which were also found related to miRNAs differently expressed in fibroblasts from IPF lungs, such the transporter SLC25A32, TUG1, EPHB6 kinase, miRNAs (miR-342 and miR-1908), and the transcription regulators FOXO1 and HNF4A. Here, HNF4A is linked to idiopathic pulmonary fibrosis.
