Abstract excerpt
Although chemicals usually induce very similar frequencies of mutations in transgenes and endogenous genes in vivo when given acutely, chronic exposure to N-ethyl-N-nitrosourea (ENU) produced a more complex pattern in which the endogenous locus was spared many mutations. Here, we demonstrate that the effect is neither ENU-specific nor locus-specific, and thus, may be important in the extrapolations of risk...
