DNA damage and repair tests for the detection of genotoxic agents
Abstract:
In vitro tests for DNA reactivity of chemicals serve several important purposes. Genotoxins can cause toxicity, teratogenicity, mutagenicity and carcinogenicity. Positive results in reliable tests are highly predictive of potential carcinogenicity. Among available tests the hepatocyte primary culture/DNA repair test, including its modifications to provide multispecies and bacterial metabolism, has been demonstrated to be a very sensitive test. Assessment of DNA reactivity of known carcinogens also provides information on their possible mechanisms of action.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
