Abstract excerpt
Most common point mutations occurring spontaneously or induced by ionizing radiation are C-->T transitions implicating cytosine as the target. Oxidative cytosine derivatives are the most abundant and mutagenic DNA damage induced by oxidative stress. Base excision repair (BER) pathway initiated by DNA glycosylases is thought to be the major pathway for the removal of these lesions. However, in alternative...
