1,8-Dinitropyrene (1,8-DNP) was clearly mutagenic at the hprt locus in CHO cells, but not detectably mutagenic in V79 cells, following a 3-h treatment period. Preliminary data indicate that CHO, but not V79, cells have measurable levels of N-acetyltransferase activity, and this may contribute to the differential sensitivity of the two cell lines to the mutagenicity of 1,8-DNP.
