Knockdown long non-coding RNA ANRIL inhibits proliferation, migration and invasion of HepG2 cells by down-regulation of miR-191

Background Hepatocellular carcinoma (HCC) is a common malignant tumor with high fatality rate. Recent studies reported that up-regulation of long non-coding RNA antisense non-coding RNA in the INK4 locus (lncRNA ANRIL) was found in HCC tissues, and which could affect HCC cells biological processes. However, the potential molecular mechanism of ANRIL in HCC is still unclear. The study aimed to uncover the effect of ANRIL on HepG2 cells growth, migration and invasion.
