Oxidative stress has been implicated in the etiology of many pathological states and known to result in
damage. Oxidative DNA damage can lead to mutagenesis (
) and has been associated with aging (
), diabetes mellitus (
), inflammatory disease (
) and carcinogenesis (
). The 8-hydroxy-2-deoxyguanosine lesion (8-OHdG) is often used in the assessment of oxidative DNA damage and has become the de facto marker for oxidative damage to DNA. 8-OHdG is one of the most prominent lesions observed following exposure to ionizing radiation (
) but also results from treatment with many xenobiotics (
) as well as by endogenous mechanisms. Thus, normal endogenous levels becomes a critical issue in the assessment of cellular 8-OHdG levels in pathological states. Furthermore, 8-OHdG is efficiently repaired by a DNA glycosylase specific for this lesion (
) and its contribution to mutagenesis is relatively weak (
). However, it is representative of approximately 20 additional oxidatively-denved lesions known to result from radiation damage (
) and whose mutagenic outcome are largely unknown in mammalian-cell systems.
