Treatment of deoxyguanosine with H2O2 (56 mM) at 37 degrees C for 2 hrs resulted in the formation of 8-hydroxydeoxyguanosine (8-OH-dG). The formation of 8-OH-dG by H2O2 was increased about 3-folds in the presence of 78 microM L-histidine (L-His). The result suggests that oxidative DNA damage induced by H2O2 in vitro might be enhanced by L-His.
