Abstract excerpt
8-Oxo-7,8-dihydroguanine (8-hydroxyguanine, G°) is a major oxidized base that is considered to play pivotal roles in the pathogenesis of various diseases, including cancer. G° induces G:C → T:A transversions at the damage site and untargeted (action-at-a-distance) mutations of G bases at 5'-GpA sequences. In this study, we examined the distribution of the action-at-a-distance mutations and the effects of the...
