What is in vivo genotoxicity testing and why is it essential?
In vivo genotoxicity testing evaluates genetic damage potential by administering test compounds to living animals, providing comprehensive assessment of chromosomal and DNA damage that accounts for complex biological processes like metabolism, distribution, and DNA repair mechanisms that in vitro tests cannot capture.
What is the Micronucleus Test (OECD 474) and when is it used?
The Micronucleus Test (OECD 474) is the gold-standard method for detecting structural or numerical chromosomal damage by measuring micronuclei formation in dividing cells, typically bone marrow or peripheral blood cells in rodents. It's essential for regulatory submissions and follow-up testing of positive in vitro results.
When should I choose the Comet Assay over other genotoxicity tests?
The Comet Assay (OECD 489) is ideal for evaluating DNA strand breaks in specific target tissues like liver, stomach, or other organs after systemic exposure. It's particularly valuable for compounds with short half-lives, reactive intermediates, or when tissue-specific genotoxicity assessment is required.
What are Transgenic Rodent Mutation Assays and their advantages?
Transgenic Rodent Mutation Assays use genetically engineered rodents carrying reporter genes to directly detect gene mutations after compound exposure. They provide unique mechanistic insights into mutagenic pathways and offer superior sensitivity for detecting mutagenic effects across multiple tissues.
