Transcriptomic analyses of IPF BALF have identified an eight−gene ferroptosis signature (NRAS, EMP1, SLC40A1, MYC, ANGPTL4, PRKCA, MUC1, GABARAPL1) that distinguishes IPF patients from healthy controls and associates with prognosis. This evidence concerns the gene EMP1 and idiopathic pulmonary fibrosis.
