Novel Long Noncoding RNA miR205HG Functions as an Esophageal Tumor-Suppressive Hedgehog Inhibitor.

ABSTRACT: Barrett's esophagus (BE) is a precursor to esophageal adenocarcinoma (EAC). Recently, long noncoding RNAs (lncRNAs) have been identified as key regulators of biological pathways. However, involvement of lncRNAs in the development of BE and EAC has not been well-studied. The aims of the current study were: (1) to study involvement of the lncRNA, miR205HG, in the development of BE and EAC; (2) to clarify the role of miR205HG in in vitro and in vivo experiments; and (3) to investigate the mechanism of miR205HG involving the Hedgehog (Hh) signaling pathway. These experiments revealed that miR205HG was downregulated in EAC vs. normal esophageal epithelia (NE) as well as in EAC cell lines, and its forced overexpression inhibited EAC cell proliferation and cell cycle p
