Over the years, toxicologists have traditionally gathered both chemical and biochemical information from biological species to assess safety while administering drugs to the human population. In order to ensure utmost safety, it is important to understand the response of biological systems to the drugs administered. The recent development and integration of “-omics” technologies into the preclinical studies have paved the way for better drug safety assessment during the drug development process. The inception of genomics has opened up countless opportunities to reinvigorate every stage of drug research and development. For the most part, “toxicogenomics” has been successfully applied to gene expression profiling and enabling a compound developing ability with predictive toxicology early in the drug development process. The gene expression profiling permits the measurement of responses and genes functionality within the genome that is being monitored. By procuring critical information at cellular and molecular levels, toxicologists can fully comprehend the underlying adverse reactions of the human body to the drugs. As it turns out, toxicogenomics proffers a strong starting point to construct experiments on drug toxicities across species with good mechanistic insights. With this technology, toxicologists now have a better knowledge base to characterize toxicities at the cellular and molecular levels, and the biomarkers needed to predict toxicity and assess safety risks.
Though the benefits of the technology are impressive, there is a limit as to how much information can be interpreted from the transcriptional changes. Gene transcription yields insights only into one portion of the biological cellular response mechanism. With the combined factor of sequencing genomes and development of DNA microarrays, gene transcription can be steered to generate multiple data points for analysis. Genomics accommodates all these data points in various screens with adaptive changes for an early toxicity prediction before it pathologically manifests. Along with silico screens and silico prediction, researchers can identify a mutagenic compound based on its chemical structure. Additionally, these data points can provide supportive evidence and mechanism of gene expression patterns to construct corresponding hypothesis and experiments during drug development and safety assessment. By establishing the underlying mechanism of an adverse drug effect, both at the cellular and molecular levels, genomics can be leveraged to design and develop a novel screen to analyze the transcriptional effects of the drug on the human body. Overall, the continued integration of genomics in drug development and safety testing will significantly enhance the comprehension of toxicities mechanism fundamentals for an efficient drug risk assessment.
