The Claim

Colorectal tumors exhibiting the colibactin mutation signature (SBS-pks) have a higher fraction of the genome altered than colorectal tumors lacking this signature.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Colorectal cancers with a specific DNA damage pattern linked to colibactin-producing bacteria show more widespread changes in their genome compared to cancers without this pattern.

See the scientific wording

Colorectal tumors with the colibactin mutation signature (SBS-pks) show a higher fraction of genome altered compared to tumors without this signature, suggesting greater genomic instability in these cancers.

What the research says

1 study

  1. Study: Abstract 2796: Colibactin mutation signatures are associated with younger age of onset in colorectal cancer

    Cancer cells with a specific DNA damage pattern caused by a gut bacteria show more broken and changed DNA than other colon cancers, meaning they're more genetically messed up.
