the activities of three human dna metabolizing enzymes -- uracil-dna glycosylase , apurinic/apyrimidinic ( ap ) -dna binding protein ( an ap-dna endonuclease ) and the major cellular deoxyribonuclease ( presumably dnase iii and/or dnase iv ) -- were measured in logarithmic growing ( diploid non-established ) fibroblast strains , tumor-derived cell lines and sv40-transformed cell lines .
