Genistein improves inflammatory response and colonic function through NF-?B signal in DSS-induced colonic injury.


ABSTRACT: This study aimed to investigate the protective potential of genistein in dextran sulfate sodium (DSS)-induced colonic injury in vitro and in vivo models. The results showed that DSS exposure caused growth suppression, colonic injury, inflammation, and barrier dysfunction in mice. Dietary genistein alleviated DSS-caused colonic injury via reducing colonic weight, rectal bleeding, and diarrhea ratio. Meanwhile, genistein reduced colonic inflammatory response via downregulating cytokines expression and improved colonic permeability and barrier in DSS-challenged mice. In Caco-2 cells, genistein improved cell viability and cellular permeability and inhibited DSS-induced activation of TLR4/NF-?B signal. In conclusion, genistein alleviated DSS-caused colonic injury, inflammation, and gut dysfunction, which might be associated with the TLR4/NF-?B signal.
