WebHyperoxic conditions alter the effects of CYP1A enzymes on oxidative stress. The upregulation of CYP1A enzymes during hypoxia results in reduction of oxidative stress-contributing F 2-isoprostanes/isofurans and DNA adducts. This reduction reduces the production of pro-inflammatory cytokines and leads to an overall reduction in HLI.
