To delve into the possible functions of 103 DEGs in HCC, we carried out GO analysis and observed that 103 DEGs were mainly associated with morphogenesis of a branching epithelium, morphogenesis of a branching structure, embryonic limb morphogenesis, collagen-containing extracellular matrix, anchored component of membrane, anchored component of plasma membrane, protein kinase activator activity, kinase activator activity and copper ion binding (Fig. 2A). This evidence concerns the gene WEE1 and hepatocellular carcinoma.
