Study Title | The effects of obesity microbiota produced metabolites on colorectal carcinogenesis in murine models |
Study Summary | Obesity is a risk factor for colorectal cancer (CRC). We aim to study the effects and mechanisms of gut microbiota of obese subjects in contributing to CRC progression. Conventional AOM-treated and ApcMin/+ mice receiving feces from obese individuals showed significantly increased colon tumor formation compared with those receiving feces from control subjects. AOM-treated mice receiving feces from obese (OB-M) exhibited microbiota dysbiosis with enriched potential pathobionts Erysipelotrichaceae bacterium GAM147, Turicibacter sp. H121, Mucinivorans hirudinis, and depleted symbionts Bacteroides vulgatus, Faecalibaculum rodentium, Bifidobacterium spp. and Lactobacillus delbrueckii. The OB-M group also showed altered gut metabolites including elevated phenylacetic acid, and depleted genipin. Moreover, OB-M group showed impaired intestinal barrier function and significant upregulation of pro-inflammatory cytokines and activation of oncogenic Wnt signaling pathway. In conclusion, gut microbiota from obese individuals promotes colorectal carcinogenesis. Microbiota modulation in obese individuals may provide new insight into obesity-driven CRC prevention and therapy. |
