Zharkov Role of base excision repair DNA glycosylases in hereditary and infectious human diseases Institute of Chemical Biology and Fundamental Medicine, Siberian Branch, Russian Academy of Sciences, Novosibirsk, 630090, RussiaReceived - 2008-01-18; Accepted - 2008-03-20 DNA glycosylases are enzymes that initiate base excision repair, which removes damaged bases from cell DNA. Recent data demonstrate that some genetic variants of two human DNA glycosylases, MUTYH and OGG1, are associated with an increased risk of cancer. In addition, various DNA glycosylases are involved in protection from some neurodegenerative diseases, immune disorders, and virus infections. On the other hand, DNA glycosylases of pathogenic microorganisms help them to evade the host defense mechanisms. Thus, DNA glycosylases are considered to be both potential therapeutic agents and drug targets.
