Utilization of a quantitative mammalian cell mutation system, CHO/HGPRT, in experimental mutagenesis and genetic toxicology
Conference
·
OSTI ID:7278027
Development of the CHO/HGPRT system is described and a host-mediated CHO/HGPRT assay is discussed. The following topics are discussed: evidence for the genetic origin of mutation induction in the CHO/HGPRT system; dose-response relationship for EMS-mediated mutation induction and cell lethality; apparent dosimetry of EMS-induced mutagenesis; structure-activity relationship of alkylating agents and ICR compounds; mutagenicity and cytotoxicity of congeners of two classes of nitrosi compounds; and preliminary validation of the CHO/HGPRT assay in predicting chemical carcinogenicity.
