Core Tip

Core tip: In this study, we compared the gene expression profile in normal esophagus and Barrett’s esophagus (BE), and found that poly(ADP-ribose) polymerase 1 (PARP1) was overexpressed in BE. In a BE model, positive staining for NF-κB, γH2AX, and PAR was observed. H2O2 and bile acids (pH 4) increased the PARP1 mRNA expression level in normal esophageal epithelial cells. PARP1 inhibition could decrease the cell viability after bile acids treatment, and increased the oxidative damage, double-strand breaks, and apoptosis. Thus, our study demonstrates a novel molecular mechanism for the role of PARP1 in the process of Barrett’s metaplasia, which sheds a potential therapeutic role for PARP1 inhibitor in BE.
