Researchers reveal how human genetics and intratumoral microbiota affect colorectal cancer

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

A recent study led by the Guangzhou Institutes of Biomedicine and Health of the Chinese Academy of Sciences has focused on this relationship and its effect on colorectal cancer. The study shows that the single-nucleotide polymorphism rs2355016—a tiny DNA change that some people carry—affects how intratumoral microbiota adhere to tumor cells, promoting CRC progression.
