Nox4 Mediates Hypoxia-Stimulated Myofibroblast Differentiation in Nasal Polyp-Derived Fibroblasts

Chronic hypoxia is associated with remodeling in various organs. Reactive oxygen species (ROS) derived from NADPH oxidases (Nox), and transforming growth factor-β(1) (TGF-β(1)) have been implicated in the pathogenesis of hypoxia-induced remodeling. The aims of this study were to determine in hypoxia-stimulated nasal polyp-derived fibroblasts (NPDF) the effect of hypoxia on the differentiation of myofibroblasts, the role of ROS, the major Nox...
