| Abstract | Hepatocellular carcinoma is an aggressive neoplasm and is one of the most common human cancers. Recently, long non-coding RNAs have been demonstrated to participate in pathogenesis of many diseases including the progression in several cancers. In this study, we found that the long non-coding RNA colon cancer–associated transcript 1 was upregulated in hepatocellular carcinoma tissues (p < 0.05), and high colon cancer–associated transcript 1 expression level was positively associated with tumor volume (p < 0.05) and American Joint Committee on Cancer stage (p < 0.05) in hepatocellular carcinoma patients. Luciferase reporter assays and RNA-pulldown assays showed that colon cancer–associated transcript 1 is a target of miR-490-3p. Real-time quantitative polymerase chain reaction and Western blot analysis indicated that colon cancer–associated transcript 1 regulated cyclin-dependent kinase 1 expression as a competing endogenous RNA by sponging miR-490-3p in hepatocellular carcinoma cells. Furthermore, colon cancer–associated transcript 1 silencing decreased hepatocellular carcinoma cells proliferation and invasion and overexpression promoted cell proliferation and invasion in vitro. These data demonstrated that the colon cancer–associated transcript 1/miR-490-3p/cyclin-dependent kinase 1 regulatory pathway promotes the progression of hepatocellular carcinoma. Inhibition of colon cancer–associated transcript 1 expression may be a novel therapeutic strategy for hepatocellular carcinoma. |
