Do biofilms confer a pro-carcinogenic state?

Research output: Contribution to journalArticlepeer-review


It is now widely recognized that a range of human diseases, including obesity, cancer and inflammatory bowel disease, is strongly linked to the microbiota. For decades, the microbiota has been proposed to contribute to the pathogenesis of colon cancer. Our recent work reveals that the organization of the mucosal microbiota into biofilms marks a subset of human colon cancer. Further, biofilm-positive colon mucosa in the colon cancer host yields an infrequently detected polyamine metabolite, N(1), N(12)-diacetylspermine, that deserves further study to determine its utility as a marker for colon neoplasia.
