What is genotoxicity studies?

Genotoxicity studies can be defined as various in-vitro and in-vivo tests designed to identify any substance or compounds which may induce damage to genetic material either directly or indirectly by various mechanisms. These tests should enable the identification of hazard with respect to DNA damage and fixation [8].Click to see full answer. Regarding this, what is meant by genotoxicity?In genetics, genotoxicity describes the property of chemical agents that damages the genetic information within a cell causing mutations, which may lead to cancer. While genotoxicity is often confused with mutagenicity, all mutagens are genotoxic, whereas not all genotoxic substances are mutagenic.Additionally, what is the difference between mutagenicity and genotoxicity? The genetic change is referred to as a mutation and the agent causing the change as a mutagen. Genotoxicity is similar to mutagenicity except that genotoxic effects are not necessarily always associated with mutations. All mutagens are genotoxic, however, not all genotoxic substances are mutagenic. Also, how do you determine genotoxicity? The most commonly applied methods for detecting genotoxicity include the bacterial Ames test, DNA strand break measurements in cells (e.g. comet assay, alkaline unwinding and hydroxyapatite chromatography, alkaline elution), and cytogenetic assays (micronucleus and chromosomal aberration assays, including the use ofWhy Genetic Toxicology is used in drug discovery?Results from genetic toxicology tests in combination with acute and subchronic animal data are used as the basis to approve clinical trials of drug candidates. Therefore, genetic toxicology testing in drug discovery and optimization serves to quickly identify mutagens and remove them from development.
