WORKSHOP AGENDA
Applications of Toxicogenomics to Cross-Species Extrapolation: A Workshop
Despite the dependence on animal models in toxicologic research for predicting human health effects in the regulatory arena, there can be significant differences between how animals and humans respond to different chemicals. This workshop will consider promises and limitations in using emerging high-throughput approaches, such as genotyping (genomics), mRNA analysis (transcriptomics), protein analysis (proteomics), and metabolite analysis (metabolomics), to inform cross-species extrapolation.

Roundtable Discussion—questions such as: • “Once a molecular basis for understanding a species differences has been established, what are the challenges to incorporating -omics information about species differences into the regulatory framework?” • “What are the advantages to using -omics compared to other approaches for detecting or explaining cross-species differences?” • “How much data are sufficient for arguing that a particular mode of action is most relevant to humans?” |
