The Claim

Mutational signature analysis via whole-genome sequencing detected colibactin-associated signatures SBS88 and ID18 in 39% of adenomas or carcinomas from patients with APC variants, compared to 11% in controls, indicating an association between colibactin-producing bacteria and specific DNA damage patterns in colorectal neoplasms.

In plain English

Researchers found that DNA damage patterns linked to a specific bacterial toxin were present in 39% of colorectal tumors from individuals with APC gene variants, compared to 11% in individuals without these tumors. This suggests a statistical relationship between the bacterial toxin and the type of DNA damage observed in these cancers.

See the scientific wording

Mutational signature analysis via whole-genome sequencing detected colibactin-associated signatures SBS88 and ID18 in 39% of adenomas or carcinomas from patients with APC variants matching these signatures, compared to 11% in controls, supporting a link between these bacterial genotoxins and specific DNA damage patterns in colorectal neoplasms.

What the research says

1 study
  1. Study: Enrichment of colibactin-associated mutational signatures in unexplained colorectal polyposis patients

    This study found that people with certain colon growths had DNA damage patterns that match those caused by a harmful gut bacteria called colibactin, and those people were also more likely to have that bacteria in their poop. So yes, the bacteria seems to be leaving a fingerprint in the DNA of these growths.
