Kurzfassung:
Reflux in correlation with diet and obesity can cause inflammation, Barrett Esophagus (BE) and Esophageal Adenocarcinoma (EAC). In L2-IL1B mice, high fat diet increased the phenotype via bile acid (BA) metabolizing microbiota and BA levels. Loss of the BA sensitive farnesoid-X-receptor (FXR) as in EAC compared to BE increased the phenotype, while its agonist obeticholic acid acted protectively, with BA levels and microbiota correlating with disease progression in mice and patients.
