The production and repair of oxidized DNA.
In order to protect DNA from oxidative damage, the cell has developed a complex defence system that includes enzymes that repair damaged bases, and proteins that target and process oxidized bases. Mammalian cells have evolved several pathways to repair oxidized DNA. In eukaryotic cells, the base excision repair pathway and its derivatives play a major role in the repair of oxidized DNA. Base excision repair removes a damaged base using a DNA glycosylase, the repair enzyme apurinic/apyrimidinic endonuclease, and DNA polymerase, β. DNA repair by base excision repair involves an ATP-dependent reaction and the concomitant incision of the oxidized base. The DNA excision repair system is also implicated in the removal of hydrogen peroxide-induced DNA damage by several lines of evidence. The principal proteins involved in DNA excision repair in mammalian cells include the apurinic/apyrimidinic endonuclease-1, DNA polymerase β, the apurinic/apyrimidinic endonuclease-1, flap endonuclease 1 and polynucleotide kinase 3′-phosphatase. In mammalian cells, the most important role of base excision repair is to repair endogenous oxidative lesions caused by free radicals generated endogenously or ingested from the environment.Wedding Dresser
