Fusobacteria Use Sugar-Binding Protein to Develop Colon Cancer

Bacteria called fusobacteria, commonly found in the mouth, use a sugar-binding protein to stick to develop colorectal polyps and cancers, suggests a new study by researchers from Harvard T.H. Chan School of Public Health and Hebrew University-Hadassah School of Dental Medicine.

While certain fusobacteria have previously been shown to worsen colorectal cancer in animals by the Garrett Lab at Harvard Chan School, this study is the first to demonstrate how they may get to and stick to developing tumors.

‘Colorectal cancer is the third leading cause of cancer-related deaths in the United States, and microbes have emerged as key factors that influence the development and progression of the disease.’

Understanding this mechanism is an important step toward fighting colorectal cancer, said co-senior study author Wendy Garrett, Melvin J. and Geraldine L. Glimcher Associate Professor of Immunology and Infectious Diseases at Harvard Chan School.

It might inform ways of blocking fusobacteria from homing in on colorectal tumors, she said. "Alternatively, and perhaps more importantly, our findings suggest that drugs targeting the same or similar mechanisms of bacterial sugar-binding proteins could potentially prevent these bacteria from exacerbating colorectal cancer."

The study will be published online in Cell Host & Microbe. Colorectal cancer is the third leading cause of cancer-related deaths in the United States, and microbes have emerged as key factors that influence the development and progression of the disease.

Garrett and co-senior study author Gilad Bachrach of Hebrew University used human samples and mouse models to confirm their new findings on fusobacteria.
