Abstract

SCOPE:

There are growing interests in using a whole-food-based approach to prevent chronic diseases due to potential synergistic interactions among different bioactive components within the whole foods. North American cranberry (Vaccinium macrocarpon), a polyphenol-rich fruit, has been shown to exert multiple beneficial health effects.

METHODS AND RESULTS:

For the first time, the protective effects of whole cranberry powder (WCP) are determined against colitis-associated mouse colon tumorigenesis induced by azoxymethane (AOM) and dextran sulfate sodium (DSS). The results show that dietary administration of WCP (1.5%, w/w in the diet) significantly suppresses colon tumorigenesis as indicated by the reduced tumor incidence, multiplicity, burden, and average tumor size in WCP-fed mice compared to the positive control mice. Both gene and protein expression levels of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α are markedly attenuated by WCP treatment in the colon of AOM/DSS-treated mice. Moreover, WCP profoundly modulates multiple signaling pathways/proteins related to inflammation, cell proliferation, apoptosis, angiogenesis, and metastasis in the colon, which is closely associated with the inhibitory effects of WCP on colon tumorigenesis.

CONCLUSION:

Overall, the results demonstrate chemopreventive effects of WCP on colon tumorigenesis in mice, providing a scientific basis for using the whole cranberry as a functional food to promote colon health in humans.
