Caffeic Acid Phenethyl Ester Administration Reduces Enterotoxigenic Bacteroides fragilis-Induced Colitis and Tumorigenesis.

ABSTRACT: The human colonic commensal enterotoxigenic Bacteroides fragilis (ETBF) is associated with chronic colitis and colon cancer. ETBF colonization induces colitis via the Bacteroides fragilis toxin (BFT). BFT secreted by ETBF cause colon inflammation via E-cadherin cleavage/NF-κB signaling. ETBF promotes colon tumorigenesis via interleukin 17A (IL-17A)/CXCL-dependent inflammation, but its bioactive therapeutics in ETBF-promoted tumorigenesis remain unexplored. In the current study, we investigated the caffeic acid phenethyl ester (CAPE) in the murine model of ETBF colitis and tumorigenesis. In this study, we observed that CAPE treatment mitigated inflammation induced by ETBF in mice. Additionally, our findings indicate that CAPE treatment offers protective effects against ETBF-en
