Research Abstract

FASn expression in Barrett's esophagus was accelerated by the mixture of bile acids and related the malignant potential of Barrett's carcinogenesis. The predictors of FASn expression were refluc esophagitis, intestinal mucin-phenotype, Cdx2 expression, accelerated cellular proliferation inhibited apoptosis (accepted by J Cilin Gastroenterol). Moreover, in the various kinds of bile acids, hydrophobic ones (LCA, GLCA, TLCA) acted as cytotoxic for Barrett's esophagus, and hydrophilic ones (UDCA, GUDCA, TUDCA) did as cytoprotective. Therefore, UDCA administration may protect the Barrett's carinigenesis (accepted by Digestive Liver Disease).
