Since the discovery of 8-OH-dG formation, various aspects of oxidative DNA damage have
been studied. For example, 2-OH-dA and a glyoxal-dG adduct were discovered as new
types of oxidative DNA damage; 2-OH-dATP was found to induce mutations and to be a
good substrate of a nucleotide sanitization enzyme, the MTH1 protein; and efforts were
continued to establish standard methodologies for 8-OH-dG analyses in urine and cellular
DNA. By these studies, we found solid chemistry-based approaches were often useful to …
