Summary: | •Berberine protects intestinal epithelial tight junctions and repairs the increasing intestinal permeability of IBS-D caused by the intestinal epithelial barrier.•Berberine reduces the expression of TNF-α and inhibits the activation of the NF-κB-MLCK pathway.•Berberine improves intestinal epithelial tight junction integrity in a mouse model of IBS-D through the expression of A20.
To investigate effects of berberine exerts on A20 expression and regulation of intestinal epithelial tight junctions via the TNF-α-NF-κB-MLCK pathway in Diarrhea-Predominant Irritable Bowel Syndrome (IBS-D).
C57BL/6 wild type (WT) and A20 IEC-KO mice (48 each) were randomly divided into normal control (NC), model control (MC), rifaximin and berberine groups (12 mice per group). An experimental model of IBS-D was established using 4% acetic acid and evaluated by haematoxylin-eosin (HE) staining. rifaximin and berberine mice were treated with rifaximin and berberine, respectively.
Intestinal epithelial space of WT berberine mice improved more than A20 IEC-KO berberine mice compared to MC mice. WT berberine mice exhibited greater expression of A20 compared with MC mice(P |
