TCGA data analysis revealed that the expression of GNA13 was inversely correlated with the expression of miR-194-5p, while lncRNA-HEIH and GNA13 expression was positively correlated, suggesting that the lncRNA-HEIH/miR-194-5p/GNA13 axis may exist in HCC tissues. This evidence concerns the gene GNA13 and hepatocellular carcinoma.
