Hemodynamic and biochemical adaptations to vascular smooth muscle overexpression of p22^phox in mice

Protein levels and polymorphisms of p22 phox have been suggested to modulate vascular NAD(P)H oxidase activity and vascular production of reactive oxygen species (ROS). We sought to determine whether increasing p22 phox expression would alter vascular ROS production and hemodynamics by targeting p22 phox expression to smooth muscle in transgenic (Tg) mice. Aortas of Tg p22smc mice had increased p22 phox and Nox1 protein levels and produced more...
