Toxicogenomics may be a subdiscipline of pharmacology that deals with the gathering , interpretation, and storage of data about gene and protein activity within a specific cell or tissue of an organism in response to exposure to toxic substances. Toxicogenomics combines toxicology with genomics or other high-throughput molecular profiling technologies like transcriptomics, proteomics and metabolomics. Toxicogenomics endeavors to elucidate the molecular mechanisms evolved within the expression of toxicity, and to derive molecular expression patterns (i.e., molecular biomarkers) that predict toxicity or the genetic susceptibility thereto . the character and complexity of the info (in volume and variability) demands highly developed processes of automated handling and storage. The analysis usually involves a good array of bioinformatics and statistics, often including statistical classification approaches.
