Oxidatively damaged bases in DNA cause many types of deleterious effects. The main enzyme that removes such lesions is DNA glycosylase, and accordingly, DNA glycosylase plays an important role in genome stability. Recently, a relationship between DNA glycosylases and aging has been suggested, but it remains controversial. Here, we investigated DNA glycosylases of C. elegans, which is a useful model...
Bacteria and eukaryotes possess redundant activities that recognize and remove oxidatively damaged bases from DNA through base excision repair. DNA glycosylases excise damaged bases to initiate the base excision repair pathway. hOgg1 and hNTH1, homologues of E. coli MutM and Nth, respectively, had been identified and characterized in human cells. Recent works revealed that human cells have three orthologues...
