Our group seeks to understand how inflammation alters the pro-carcinogenic capabilities of the microbiota, with the long-term goal of targeting resident microbes as a preventative and therapeutic strategy to lessen inflammation and reduce the risk of colorectal cancer.  Our general approach combines genomics, bioinformatics, immunology, bacterial cultivation techniques and gnotobiotic mouse models to identify inflammatory and pro-carcinogenic bacteria from human patients and uncover mechanisms by which these bacteria promote inflammation and neoplasia.  We are currently focusing upon clinical strains of intestinal E. coli isolated directly from human inflammatory bowel disease (IBD) patients, who are known to experience a high risk of colorectal cancer.  We are evaluating the ability of these resident microorganisms to induce inflammation and tumorigenesis in mouse models and defining functional capabilities, microbial genes and pathways that are causally and mechanistically linked to carcinogenesis.  Ultimately this research will uncover novel microbial targets will enable us to manipulate the intestinal microbiota as a therapeutic target for human digestive diseases and cancer.
