• Expose rat cells in primary culture to a variety of toxicants; evaluate gene expression.
• Expose intact animal to same toxicants; evaluate gene expression in interested organ.
• Expose human cells in primary culture to same toxicants; evaluate gene expression.
• Predict in vivo human response.

Development of SNP-ChipsHigh throughput genotyping using DNA microarray technology will be used to allow facile genetic screening of human populations for:
• Adverse Drug Reactions• Cancer Susceptibility, Early Diagnosis & Recurrence • Drug Efficacy in Subsets of the Population• Individualized Drug Dosing
Rapid screening for variant genes involved in metabolism, DNA repair, and cellular homeostasis should allow the selection of genetically heterogeneous groups for inclusion in clinical trials and thereby increase our ability to protect public health in a diverse population.
