Research Abstract |
The role of reactive oxygen species for cell phenotypic changes was investigated in glomerulonephritis (GN). Increased ROS production was observed in crescents of GN. The increased ROS production was associated with enhanced Nox2 (an NADPH component) expression and parietal epithelial cell proliferation. We also observed the expressions of angiotensin II and its receptor. In addition, cultured glomerular cells stimulated with angiotensin II and H2O2 showed the enhanced phosphorylation of Erk5, a ROS-related MAPK family. Inhibition with siRNA showed that ROS-MAP kinase signaling pathway might enhance cell potential to survive, and thereby play a role in progression of glomerulonephritis.
