A collaboration of the Quirke and Huttenhower labs has led to the publication of two papers, in Clinical Cancer Research and Genome Medicine, that report a microbiome signature that is associated with colorectal cancer and is consistent between developed and developing countries. These findings suggest that a microbiome-based qPCR test could be an affordable tool to enhance accuracy of CRC screening.  To learn more about this work and its implications see this blog on the Cancer Grand Challenges website.
