Using a gut-specifc ApcMin/+ mouse model, the efects of oral BE on the life span, organ index, and tumor multiplicity wereevaluated. The expressions of infammatory cytokines were determined using ELISA. To verify the in vivo data, the antiinfammatory and antiproliferative efects of BE were determined with an in vitro cell model.Results HPLC analysis showed that BI was quickly transformed into BE by the intestinal microbiota. Oral BE (30 mg/kg/day) signifcantly increased the life span, from 125.2 to 218.4 days (P
