Abstract
Chinese hamster ovary (CHO) cell lines heterozygous at the adenine phosphoribosyltransferase (aprt) and thymidine kinase (tk) loci were isolated and used for single-step selection of spontaneous and induced mutants resistant to 8-azaadenine (AAr), 6-thioguanine (TGr), 5-fluorodeoxyuridine (FUdRr), or ouabain (OUAR). Mutation data are reported for direct mutagens ethyl methanesulfonate (EMS), N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), 4-nitroquinoline-1-oxide (NQO) and for promutagens dimethylnitrosamine (DMN) and benzo(a)pyrene (BaP) activated by rat liver homogenates. Critical plating densities were established for AAr, TGr, and FUdRr. Optimal expression of mutant phenotypes after mutation induction with EMS, DMN, or BaP were 2 to 4 d for AAr, 6 to 8 d for TGr, 3 d for OUAR, and 1 to 3 d for FUdRr. The induced mutant frequencies as a function of relative cell survival after treatment with EMS, DMN, or BaP showed locus-specific differences in sensitivity. Of 61 clonal isolates resistant to AA and assayed for APRT activity, 87% had < or = 5% wild type activity; of 30 TGr clones assayed, 83% had < or = 5% wild type HGPRT activity. Of 42 FUdRr clones assayed, 41 had <1% wild type TK activity. Fifty clones selected in medium containing FUdR displayed cross-resistance to 5-bromodeoxyuridine (BUdR) and trifluorothymidine (TFT) and all were sensitive to HAT (amethopterin-hypoxanthine-thymidine) medium. The tk locus showed the largest mutational response as a function of relative cell survival after mutagen treatment.
