Human A549 lung epithelial cells were challenged with 18O-labeled hydrogen peroxide ([18O]-H2O2), the total RNA and DNA extracted in parallel, and analyzed for 18O-labeled 8-oxo-7,8-dihydroguanosine ([18O]-8-oxoGuo) and 8-oxo-7,8-dihydro-2?-deoxyguanosine ([18O]-8-oxodGuo) respectively, using high-performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC-MS/MS)...
