Abstract

The endogenous production of oxidative damage in DNA by free radicals released as a by-product of respiration is a likely cause of mutations which, if they occur in appropriate genes, may lead to cancer. Using an endonuclease specific for oxidized pyrimidines, in conjunction with the highly sensitive method of single cell gel electrophoresis, we have detected significant oxidative damage in untreated, freshly isolated lymphocytes from normal, healthy individuals.
