Abstract |
Esophageal cancer is one of the most common digestive malignant diseases worldwide and emerging evidences revealed that microRNAs (miRNAs) were implicated in the development and progression of esophageal cancer. However, the expression level and biological function of microRNA-873(miR-873) in esophageal cancer are still largely elusive. In this study, we investigated the expression and biological roles of miR-873 in human esophageal cancer. Our results revealed that miR-873 was significantly underexpressed in esophageal cancer tissues and cell lines when compared with the para-tumor tissue and primary human esophageal epithelial cells. Furthermore, overexpression of miR-873 could remarkably inhibit esophageal cancer cell growth, migration and invasion. Moreover, we validated differentiated embryonic chondrocyte expressed gene 2 (DEC2) as a direct target of miR-873 which could reverse the repressive effects of miR-873 on esophageal cancer cell. In summary, our investigation demonstrated that miR-873 was underexpressed in esophageal cancer and might act as a tumor suppressor gene by directly targeting DEC2.
