Clastogen

Summary
A clastogen is a mutagenic agent that disturbs normal DNA related processes or directly causes DNA strand breakages, thus causing the deletion, insertion, or rearrangement of entire chromosome sections. These processes are a form of mutagenesis which if left unrepaired, or improperly repaired, can lead to cancer. Known clastogens include acridine yellow, benzene, ethylene oxide, arsenic, phosphine, mimosine, actinomycin D, camptothecin, methotrexate, methyl acrylate, resorcinol and 5-fluorodeoxyuridine. Additionally, 1,2-dimethylhydrazine is a known colon carcinogen and shows signs of possessing clastogenic activity. There are many clastogens not listed here and research is ongoing to discover new clastogens. Some known clastogens only exhibit clastogenic activity in certain cell types, such as caffeine which exhibits clastogenic activity in plant cells. Researchers are interested in clastogens for researching cancer, as well as for other human health concern
