IGF2-AS and hepatocellular carcinoma: Emerging evidence has indicated the important role of lncRNA in the multiple cancer tumorigenesis, especially in HCC.6, 7 For example, lncRNA UBE2CP3 was frequently up‐regulated in HCC samples and promotes hepatocellular carcinoma tumour metastasis via regulating epithelial‐mesenchymal transition and inducing cell invasion and migration.8 LncRNA Igf2as was upregulated in HCC cells and tissues and controlled hepatocellular carcinoma progression through the ERK/MAPK signalling pathway.9
