Scientists finally solved how a common gut bacterium triggers colon cancer
Researchers at Johns Hopkins have identified a specific host protein, claudin-4, that allows a gut bacterium toxin to damage colon cells. This discovery could lead to new therapeutic strategies for preventing colorectal cancer.
Why it matters
Understanding the mechanism of bacterial-induced inflammation provides a potential pathway for early detection and treatment of colon-related diseases.
Scientists have uncovered how a toxin produced by a common gut bacterium gains access to colon cells, solving a mystery that has puzzled researchers for more than 15 years. The discovery not only explains how the toxin begins damaging the colon, but also points to a possible new way to block its effects before they contribute to colorectal cancer.
