The observation that PARP inhibition partly rescues vitamin C-treated cells may suggest that the toxic effect of DHA uptake is not caused by ROS alone, since restoring NAD + levels and glycolysis with the PARP inhibitor may actually decrease PPP flux and NADPH production, and aggravate the redox stress
The first one is synthesized through three steps, starting with the conversion of nicotinic acid into NAD, utilizing nicotinic acid mononucleotide and nicotinic acid adenine dinucleotide, while the second one is achieved by the action of enzyme NAD+ kinase, which phosphorylates NAD (, , )
