To identify the signalling pathway underlying the effects of the Circ_0003945/miR‐34c‐5p/LGR4 axis on HCC cells, KEGG analysis (Entry:map 04310) and previous studies showed that LGR4 is the key gene in the Wnt/β‐catenin pathway.25, 26. This evidence concerns the gene LGR4 and hepatocellular carcinoma.
