| abstractText | Sulforaphane (SFN) is an isothiocyanate that is present abundantly in widely consumed cruciferous vegetables and has a particularly high content in broccoli and cauliflower. It has been shown to be an effective inhibitor of some carcinogen-induced cancers in rodents. Here, we investigated the chemopreventive efficacy of SFN in the ApcMin/+ mouse model. ApcMin/+ mice were fed with diet supplemented with two different dose levels of SFN (300 and 600 p.p.m.) for 3 weeks. Our results clearly demonstrated that ApcMin/+ mice fed with SFN-supplemented diet developed significantly less and smaller polyps with higher apoptotic and lower proliferative indices in their small intestine, in a SFN dose-dependent manner. In addition, immunohistochemical (IHC) staining of the adenomas indicated that SFN significantly suppressed the expression of phosphorylated c-Jun N-terminal kinase (p-JNK), phosphorylated extracellular signal-regulated kinases (p-ERK) and phosphorylated-Akt (p-Akt), which were found to be highly expressed in the adenomas of ApcMin/+ mice. In contrast, expression of two important biomarkers of the Wnt signaling pathway, beta-catenin and cyclin-D1 was unaffected by SFN treatment. Measurement of SFN and its metabolite SFN-GSH in the small intestine using LC-MS indicates that the concentrations between 3 and 30 nmol/g are required to prevent, or retard adenoma formation in the gastrointestinal tract of ApcMin/+ mice. |
