We conclude that: (i) suppression of specific transcription factor functions can potentially serve as a marker of exposure to oxidative stress and its effects on human lymphocytes ; (ii) lipid peroxidation is only detectable in human lymphocytes upon exposure to weak oxidative stress which does not induce catalase activity ; (iii) therefore, transcription factor DNA-binding activities are more sensitive to oxidative stress than lipid peroxidation .
