Unfortunately, we were unable to obtain specific staining with antibodies to 8-OH-dG.
This enzyme is the major repair enzyme involved in the defense against accumulation of the 8-OH-dG adducts discussed above.
However, the nuclear localization of 8-OH-dG [ 32 ] and the increased Ogg1 reported here are consistent with a model in which mitochondrial Ogg1 is up-regulated but nuclear Ogg1 is not, leading to an increase in nuclear but not mitochondrial 8-OH-dG adducts [ 32 ] . Further studies will be required to resolve this issue, but β-cells in type 2 diabetes may well suffer from both nuclear and mitochondrial DNA damage, leading to decreased β-cell function and eventual loss of β-cell mass.
Ogg1 knockout mice possess increased levels of 8-OH-dG in their genome, particularly in the mitochondrial genome, but do not seem to exhibit an increased frequency of malignancies [ 44 45 46 ] . It was postulated that the consequences of 8-OH-dG adducts and Ogg1 deficiency affects mainly cells with high oxygen metabolism and slow proliferation, such as liver cells [ 45 ] . While β-cells were not examined in that study, they certainly exhibit both high oxidative metabolism and a low rate of proliferation, consistent with them being a target for the effects of 8-OH-dG adducts.
Increases in Ogg1 activity and expression have been found by a number of investigators [ 35 36 37 ] . Although antibodies to 8-OH-dG exist [ 38 ] , Ogg1 was used as a surrogate for the amount of oxidative DNA damage.
