BACKGROUND: In animals and humans black raspberries (BRBs) have chemo-preventative effects against Wnt driven colorectal cancer (CRC). While BRBs have made it into clinical trials, the exact mechanisms of BRB action remain unclear. Potentially the chemo-preventative properties are linked to their impact on the gut microbiome, as diet is known to influence the microbial diversity of the gut and plays a key role in regulating intestinal homeostasis and the aetiology of CRC. OBJECTIVE: To determine the impact of a BRB diet on themicrobial biodiversityof thewild-type and malignant mouse intestine. METHODS: Adult mice in which Wnt driven tumourigenesis could be initiated by conditional deletion of Apc in the intestinal stem cell (Lgr5CreERT2) were administered a 10% BRB diet. Total DNA from faecal pellets pre- and post-BRB exposure was used for longitudinal metataxonomic analysis of the V1 to V3 regions of the 16S rRNA gene. RESULTS: Individually BRB intervention and Apc loss alter the microbial community of the gut. In combination, the microbiome changes observed in the Apc deficient intestine are attenuated upon administration of a BRB diet. CONCLUSIONS: Our results suggest that BRB intervention may protectively regulate the gut microbiota in the healthy and malignant intestine.
