Nrf2 induces the expression of antioxidant genes including glutathione S-transferase (GST), NAD(P)H: quinone oxidoreductase 1 (NQO1), Hemeoxygenase1 (HO1), and ferritin heavy chain 1 (FTH1), which have been shown to protect against pulmonary fibrosis in murine models [11–13]. This evidence concerns the gene NQO1 and pulmonary fibrosis.
