Circular RNA hsa_Circ_101141 as a Competing Endogenous RNA Facilitates Tumorigenesis of Hepatocellular Carcinoma by Regulating miR-1297/ROCK1 Pathway.

ABSTRACT: As a novel class of noncoding RNAs, circular RNAs (circRNAs) have been recently reported to be involved in cell development and function. However, the functional role of circRNAs in hepatocellular carcinoma (HCC) remains unclear. In the present study, we found that the expression of human circ_101141 was upregulated in HCC tissues and cells. In addition, downregulation of circ_101141 dramatically inhibited cell proliferation, migration, and invasion in HCC cells. In addition, by using the bioinformatics tools, the potential target of circ_101141 was predicted. Mechanistic investigations indicated that circ_101141 acted as a miR-1297 "sponge"; meanwhile, Rho-associated, coiled-coil-containing protein kinase 1 (ROCK1) was a direct target of miR-1297. Further experiments demonstrated that cir
