CCNA2 and cancer: The miR-424 binding site was found in the CCNA2 3′-UTR, and miR-424 targets CCNA2 directly by binding to the coding region of CCNA2, which can not only contribute to the differentiation of myoblast cells and cellular processes such as differentiation and epithelial-to-mesenchymal transition of cancer cells but also modulate the chemosensitivity of tumor cells toward anticancer drugs.
