In the metabolically competent genetically engineered human lymphoblastoid cell line, MCL-5, DNA damage and genetic changes were investigated after treatment with environmentally relevant chemicals from different classes of substances. The genotoxicity of the chemicals was evaluated by the extent of DNA strand breaks revealed by alkaline single cell gel electrophoresis. Concentrations of the DNA adduct 8-OHdG in genomic DNA were measured as a marker for oxidative stress. Frequencies of three potentially oncogenic mutations, point mutations at codons 248 or 12 of thep53-or K-ras-genes, respectively, and the translocation t(14; 18), were determined with and without previous chemical treatment.
