Microbial Link Between Western-style Diet and Colon Cancer Risk

Investigators from Brigham and Women’s Hospital with collaborators looked at data from more than 134,000 participants from two U.S.-wide prospective cohort studies. The team analyzed dietary patterns as well as DNA from Escherichia coli strains found in more than 1,000 colorectal tumors. The team looked for bacterial strains carrying a distinct genetic island known as polyketide synthase (pks). Pks encodes an enzyme that has been shown to cause mutations in human cells. Overall, the team found that Western diet was associated with colorectal tumors containing high amounts of pks+ E. coli but not with tumors containing little to no amount of pks+ E. coli.
