“At the time at which the maximum induction was observed, which coincided between experiments, the frequency of micronuclei induced by benzo(a)pyrene was reduced by 41-61% and that induced by mitomycin C was reduced by 44-71% in the presence of beta-carotene.”
“Our results suggest that beta-carotene provides significant protection against the genotoxicity of benzo(a)pyrene and mitomycin C.”
