Resveratrol inhibits bile acid-induced gastric intestinal metaplasia via the PI3K/AKT/p-FoxO4 signalling pathway.

ABSTRACT: Gastric intestinal metaplasia (GIM) is the essential pre-malignancy of gastric cancer. Chronic inflammation and bile acid reflux are major contributing factors. As an intestinal development transcription factor, caudal-related homeobox 2 (CDX2) is key in GIM. Resveratrol has potential chemopreventive and anti-tumour effects. The aim of the study is to probe the effect of resveratrol in bile acid-induced GIM. We demonstrated that resveratrol could reduce CDX2 expression in a time- and dose-dependent manner in gastric cell lines. A Cignal Finder 45-Pathway Reporter Array and TranSignal Protein/DNA Array Kit verified that resveratrol could increase Forkhead box O4 (FoxO4) activity and that Chenodeoxycholic acid (CDCA) could reduce FoxO4 activity. Furthermore, bioinformatics analysis showed th
