Abstract excerpt
DNA oxidation is a serious threat to genome integrity and is involved in mutations and cancer initiation. The G base is most frequently damaged, and 8-oxo-7,8-dihydroguanine (GO, 8-hydroxyguanine) is one of the predominant damaged bases. In human cells, GO causes a G:C→T:A transversion mutation at the modified site, and also induces untargeted substitution mutations at the G bases of 5'-GpA-3' dinucleotides...
