MiR-214 inhibits cell growth in hepatocellular carcinoma through suppression of β-catenin

► miR-214 is frequently downregulated in human HCC cell lines and tissues. ► miR-214 overexpression inhibits HCC cell growth in vitro and in vivo. ► miR-214 directly targets β-catenin 3′-UTR in HCC cells. ► miR-214 regulates β-catenin downstream signaling molecules.
