title: Effects of 4-nitroquinoline 1-oxide on the DNA-protein complex.
abstract: The effects of 4-nitroquinoline 1-oxide (4NQO), a well known carcinogenic compound, on the DNA-protein complex and DNA Folding Proteins were investigated. FM3A cells were treated with 10(-6) M or 10(-5) M 4NQO for 30 min. Treatment with the 10(-6) M concentration was confirmed to cause the sedimentation of the DNA-protein complex to become slower. DNA Folding Proteins were then isolated from 4NQO-treated and untreated control cells and analyzed by SDS-polyacrylamide gel electrophoresis. No appreciable differences in the amounts of the major components of DNA Folding Proteins could be found due to 4NQO-treatment, but the 92 K protein was induced in DNA-protein complex by treatment with 4NQO.
