NFE2L2 and pulmonary fibrosis: 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].
