NCIt definition : Toxicogenomics is a new scientific field that elucidates how the entire genome is
involved in biological responses of organisms exposed to environmental toxicants/stressors.
Toxicogenomics combines information from studies of genomic-scale mRNA profiling (by
microarray analysis), cell-wide or tissue-wide protein profiling (proteomics), genetic
susceptibility, and computational models to understand the roles of gene-environment
interactions in disease. (from National Center for Toxicogenomics homepage);
