Nrf2 deficiency enhances the levels of several proinflammatory cytokines implicated in the pathogenesis of VILI. We found diminished levels of critical antioxidant enzymes and redox imbalance by MV in the lungs of Nrf2\u2212\/\u2212 mice; however, antioxidant supplementation to Nrf2\u2212\/\u2212 mice remarkably attenuated VILI. When subjected to a clinically relevant prolong period of MV, Nrf2\u2212\/\u2212 mice displayed greater levels of VILI than Nrf2+\/+ mice. Expression profiling revealed lack of induction of several VILI genes, stress response and solute carrier proteins, and phosphatases in Nrf2\u2212\/\u2212 mice.<\/jats:p>\n
