Background: Although ethanol itself is not genotoxic, chronic alcohol consumption increases the risk of neoplastic disease. The mechanism by which ethanol exerts a cocarcinogenic effect is not well established, and the aim of this study was to determine whether exposure to ethanol increased the cytotoxicity of known carcinogens.
Methods: To assess cell survival, the ability of Chinese hamster A10 cells, which express alcohol dehydrogenase, to form colonies was determined after exposure to ethanol and other substances, including both genotoxicants and non-DNA-reactive cytotoxic agents.
