ANXA2 and hepatocellular carcinoma: LncRNA-MUF not only function as ceRNAs to regulate miRNAs, but also acts as a scaffold to enhance the interaction between GSK-3β (Glycogen synthase kinase-3β) and ANXA2 (Annexin A2), thus leading to the activation of Wnt/β-catenin signal transduction pathway and driving HCC metastasis [42].
