Wound-healing role for microRNAs in colon offer new insight to inflammatory bowel diseases

A microRNA cluster believed to be important for suppressing colon cancer has been found to play a critical role in wound healing in the intestine, cancer researchers have found. The findings, first discovered in mice and later reproduced in human cells, could provide a fresh avenue for investigating chronic digestive diseases and for potentially repairing damage in these and other disease or injury settings.
