Butyrate paradox. (a) Effect of different levels of butyrate in Azoxymethane/Dextran sodium sulphate (AOM/DSS) treated mouse model. DSS is a colon epithelium disrupting agent that can induce colitis and AOM is a genotoxin. Combined AOM and DSS treatment in mice creates a model similar to that of human CRC to study the effects of inflammation and underlying genetic mutations in colon epithelium cells on microbiota dysbiosis and tumourigenesis [127]; (b) effect of moderate levels of butyrate on adenomatous polyposis coli (APC)/ MutS protein homolog 2 (Msh2) mouse model.
