Using engineered bacteria to target harmful toxins linked to colorectal cancer

Targeting a human gut bacterial genotoxin via engineered commensal bacteria

NIH-funded research University of Michigan at Ann Arbor · NIH-11103445

This study is exploring how specially modified E. coli bacteria can help fight a harmful toxin linked to colorectal cancer by using an enzyme to block its effects, with the goal of creating a new treatment option for people at risk of this type of cancer.

What this research studies

This research investigates how engineered strains of E. coli can be used to neutralize a harmful bacterial toxin called colibactin, which is associated with colorectal cancer. The approach involves displaying an enzyme on the surface of these bacteria that can inactivate colibactin, thereby preventing DNA damage and tumor formation. By studying this interaction in cell lines and mouse models, the research aims to develop a novel therapeutic strategy to combat cancer caused by these bacteria.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals at risk for colorectal cancer, particularly those with a history of colibactin-producing bacterial colonization.

Not a fit: Patients who do not have colorectal cancer or are not colonized by colibactin-producing bacteria may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that reduce the risk of colorectal cancer associated with harmful gut bacteria.

How similar studies have performed: Previous studies have shown promise in using engineered bacteria for therapeutic purposes, suggesting potential success for this novel approach.
