Female BALB/c mice were fed either a fibre-free diet or one supplemented with 30% wheat-bran for 5 weeks. The ability of these mice to convert MeIQ to a bacteria mutagen in vivo was determined using intrasanguinous host-mediated bacterial mutation assays. Less mutagenic activity was detected in the livers of mice fed the bran-supplemented diet compared with those fed the fibre-free diet. Subsequent experiments demonstrated that the effect of brain was not due to modifications in hepatic metabolism, but to changes in uptake of MeIQ from the gastrointestinal tract. © 1989.
