It also decreased the expression of pro‐inflammatory cytokines, such as IL‐13 and CD30L, in IBD and CAC model mice possibly by inhibiting Toll‐like receptor 4 (TLR4)/NF‐κB signalling and the expression of colon cancer markers, such as carcinoembryonic antigen, cytokeratin 8, CK18 and p53, in CAC model mice. The gene discussed is TLR4; the disease is inflammatory bowel disease.
