Zusammenfassung
Hyperglycemia increases reactive oxygen species (ROS) production e.g. with subsequent activation of the Protein kinase C (PKC) signalling pathway. It has been postulated that a positive feedback loop may occur between ROS and the activation of PKC-ζ as in the diabetic state the PKC-ζ (PKC-ζ) isoform is required for ROS generation from nicotinamide adenine dinucleotide phosphate (NADPH) oxidase in mesangial cells exposed to high glucose condition. Furthermore, the requirement of PKC-zeta for F-actin disassembly may involve ROS. Therefore, deletion of PKC-ζ in vivo should result in prevention of experimental diabe…
