Better Predictive Tests • DNA- and protein-based technologies • Transgenics • Biomarkers (rodent/human homologues) • Alternative to animals • Computational Science
Current Genomics Project at the NCTR • Human genotyping • Gene expression profiles
NCTR Gene Expression Microarray Project Effects of Chemical Toxicants on Gene Expression Profiles • 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-Chips • High 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.
Problems • Commercial vs. In-house development of chips • Toxicogenomics staffing
Some Solutions • Creative recruitment (Cellular and Molecular Toxicology Group) • Leveraging • Collaboration • IPA
