Studies on DSS-induced colitis also report that KO supplementation increased the mRNA expression level of Muc6 (Mucin 6), TJ-related genes, claudin-1, occludin, and zonula occludens (ZO)-1, and reduced serum levels of LPS and diamine oxidase (DAO), indicating a decrease in intestinal permeability [64,65,66]. The gene discussed is MUC6; the disease is colitis.
