Chen et al. proved that during intrahepatic vascular metastasis of hepatocellular carcinoma, the expression of lncRNA-CDKN2B-AS was increased, and the expression of metastasis-related gene ARHGAP18 was upregulated through the competitive binding of miRNA-153-5p by lncRNA-CDKN2B-AS [32]. Here, ARHGAP18 is linked to hepatocellular carcinoma.
