PBX3 and hepatocellular carcinoma: The suppression effect of miR-33a-3p on growth and metastasis of HCC cells is mediated, at least in part, through direct destabilization of the mRNAs of PBX3. Thus, these findings may help to better understand the mechanisms involved in HCC metastasis, and to discover novel and sensitive prognostic or therapeutic molecular targets for HCC.
