High performance liquid chromatography and tandem mass spectrometry disclosed at least 10 lipid peroxidation related modified DNA bases in the DNAs extracted under anti-oxidation condition from human autopsy tissues. Among these 10 DNA adducts, 7 of them, 1, N6-etheno-2'-deoxyadenosine(εdA), butanone-etheno-2'-deoxycytidine(BεdC), butanone-etheno-2'-deoxy-5-methylcytidine(BεmedC), butanoneetheno-2'-deoxyadenosine(BεdA), heptanone-etheno-2'-deoxycytidine(HεdC), heptanone-etheno-2'-deoxyadenosine(HεdA), and heptanone-etheno-2'-deoxyguanosine(HεdG) were quantitated in gastric mucosa, resected for gastric cancer in Japan and China. The profiles of these DNA adducts identified the origin of the tissues(China or Japan), implying adductome profile may reflect environmental exposures of individual settings. We further tested the repair machinery against these modified bases and discovered TDG play s role in repairing some of these adducts.
