Genetic toxicology: current status of methods of carcinogen identification.

R W Tennant 1, E Zeiger 1
PMCID: PMC1519583  PMID: 8354178

Abstract

A critical aspect of the efforts to relate the results of short-term genetic toxicity tests with those from long-term rodent tests for carcinogens is the quality and consistency of the studies conducted by the National Toxicology Program. Analysis of the results in relationship to chemical structure has shown that mutagenic potential is a primary risk factor for carcinogen identification. Chemicals positive in the Salmonella assay-generally possess "structural alerts" for electrophilic interactions, are predominantly represented among chemicals producing trans-species carcinogenic effects in rodents, and among those identified as carcinogenic to humans. Current efforts are aimed at defining toxicological, structural, and mechanistic properties of nonmutagens that are carcinogenic in rodents.
