In this study, the effects of dietary plant-origin glucosylceramide (GlcCer) on colon cytokine contents were investigated in 1,2-dimethylhydrazine (DMH)-treated mice, a model of colon cancer. DMH treatment induced the formation of aberrant crypt foci (ACF) and the production of inflammatory cytokines and chemokaines. Dietary GlcCer suppressed ACF formation and cytokine production in these mice. In particular, chemokine production was suppressed by dietary GlcCer. These GlcCer-related trends of suppression were similar to those observed in our previous study on dextran sulfate sodium salt (DSS)-treated mice. These results provide further evidence for the suppression of DMH-induced inflammation by dietary GlcCer.
