| Outline of Final Research Achievements |
Stroke, myocardial infarction, and arteriosclerosis obliterans are representative adult vascular diseases to be overcome. Although there are many sizes of vascular vessels, endothelial cells cover intraluminal sides of any vascular vessels. Because there is abundant molecular oxygen within the arteries, reactive oxygen species (ROS) can be easily produced in endothelial cells and be associated with the development and progression of the vascular diseases. Thus, it is indispensable for overcoming of the vascular diseases to understand well the mechanisms by which ROS are produced and regulated in endothelial cells. In the present study, I elucidate ischemic/hypoxic responses and pathological roles mediated by ROS-producing Nox4 in endothelial cells.
