| Research Abstract |
High glucose was shown to elicit reactive oxygen species (ROS) production and induce apoptosis accompanied by activation of p38 mitogen-activated protein kinase (MAPK). We have reported that naofen, a novel WD40-repeat protein, may mediate apoptosis through caspase-3 activation. The present study was undertaken to investigate the potential involvement of naofen in diabetic angiopathy. Our results indicate that enhanced expression of naofen in vascular endothelial cells in kidney of streptozotocin-induced diabetic rats, also in high glucose-treated rat arterial endothelial cells. Furthermore, ROS generation, p38 MAPK activation and NF-κB activation, may be involved in high glucose-induced increase in naofen expression.
