Recently, we identified real-time polymerase chain reaction (PCR), from healthy colonic mucosa of IBD patients, a molecular signature of IBD involving 10 microRNA (miRNA) Common (miR26a, miR29a, miR29b, miR126 * miR15a, miR127-3p, miR324 -3p, miR30c, miR185, miR196a) and 15 colic chronic disease (MC) and ulcerative colitis (RCH) discriminating microRNA (miR-142-3p, miR-142-5p, miR-146a, miR-146b-5p, miR150, miR-181d, miR-182, miR199a -3p, miR199a-5p, miR199b-5p, miR-203, miR223, miR-299-5p, miR320a, miR-328).
