NOX4 Mediates -Induced Nuclear Reactive Oxygen Species Generation and Chromatin Remodeling in Lung Epithelium.

() infection increases reactive oxygen species (ROS), and earlier, we have shown a role for NADPH oxidase-derived ROS in -mediated lung inflammation and injury. Here, we show a role for the lung epithelial cell (LEpC) NOX4 in -mediated chromatin remodeling and lung inflammation. Intratracheal administration of to Nox4 mice for 24 h caused lung inflammatory injury; however, epithelial cell-deleted Nox4 mice exhibited reduced lung inflammatory injury, oxidative stress, secretion of pro-inflammatory cytokines, and decreased histone acetylation.
