MEIS2 and hepatocellular carcinoma: Considering the transcriptional property of MEIS2 family and the correlation expression between MEIS2C/D and miR-1307-3p in HCC patients, our studies demonstrate that miR-1307-3p is one of the key components of the MEIS2D circuit, whereby the expression of miR-1307-3p is driven by MEIS2D in HCC cells.
