MEG3 and hepatocellular carcinoma: Flow cytometry analysis showed MEG3 over-expression (huh7 cell apoptotic rate, 31.15%; SK-HEP-1 cell apoptotic rate, 33.47%) significantly induced the apoptosis of HCC cell compared to MEG3 plasmid combined with miR-9-5p mimics transfection group (huh7 cell, 18.69%; SK-HEP-1cell, 22.56%) and the control group (pcDNA + miR mimics) (huh7 cell, 18.19%; SK-HEP-1cell, 21.89%).
