Gene mutation, quantitative mutagenesis, and mutagen screening in mammalian cells: study with the CHO/HGPRT system
We have employed CHO cells to develop and define a set of stringent conditions for studying mutation induction to TG resistance. Several lines of evidence support the CHO/HGPRT system as a specific-locus mutational assay. The system permits quantification of mutation at the HGPRT locus induced by various physical and chemical mutagens. The quantitative nature of the system provides a basis for the study of structure-function relationships of various classes of chemical mutagens. The intra- and interlaboratory reproducibility of this system suggests its potential for screening environmental agents for mutagenic activity.
