MUC5AC and ulcerative colitis: More recently, a human colonic mucin microarray was constructed with colonic mucin from patients with colon cancer (healthy tissue away from the tumour site; control, n = 7) and ulcerative colitis (UC, n = 5) in a similar manner to the natural mucin microarray [36] and was used to profile the interactions of the commensal microbes Akkermansia muciniphila and Desulfovibrio spp.
