NQO1 and acute myeloid leukemia: The VDD/CA-induced differentiation was associated with lowered intracellular levels of reactive oxygen species (ROS), upregulated expression of antioxidant enzymes, such as NAD(P)H quinone oxidoreductase-1 (NQO1) and the rate-limiting glutathione-synthesizing enzyme γ-glutamylcysteine synthetase (γGCS), and increased total glutathione content in AML cells [22,23,24].
