GSTP1 and bronchopulmonary dysplasia: Even though this study did not reveal any differences in Nrf-2’s target antioxidant response elements, specifically for SNPs of glutamate-cysteine ligase catalytic subunit (GCLC), glutathione S-transferase Pi 1 (GSTP1), heme oxygenase 1 (HOX1), and NADPH: quinone oxidoreductase 1 (NQO1), later studies have revealed SNPs that may have an association with BPD [58,59].
