It appears that the labile iron pool (LIP, low molecular weight iron) presence in cells can result in the production of reactive oxygen species (ROS). ROS may be responsible for the formation of 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo) in cellular DNA. In the present study we report on the relationship between LIP and the endogenous level of 8-oxodGuo in human lymphocytes. Good correlation has been determined between LIP and the oxidatively modified nucleoside. This in turn points out the possibility that under physiological condition there is the availability of LIP for catalyzing Fenton-type reactions in close proximity to cellular DNA.
