However, in dMMR/MSH mice, butyrate leads to hyperproliferation [102], suspends tumor growth and reserves microbial homeostasis by upregulating TLR4 expression and phosphorylation of MAPKs and NF-κΒ in human colon cancer SW480 cells or mouse colon cancer CT26 cells [103]. Here, TLR4 is linked to colonic neoplasm.
