Toxicogenomics studies that employ the polymerase chain reaction (PCR) technique evaluate the biological response to a toxicological challenge at the level of individual genes or a small set of genes. PCR is often used to test specific gene-level hypotheses related to a toxicological challenge or validate results from larger scale microarray studies. Data are reported as the expression of a number of genes related to toxicology under different conditions.
