MIR31HG were downregulated in HCC cell lines and tissues and was associated with the poor survival of patients and was predominantly localized in the cell cytoplasm. a Expression levels of MIR31HG in HCC cell lines and L02 cells (**P < 0.01). b Expression levels of MIR31HG in HCC samples and adjacent non-tumor tissues (P < 0.01). c Kaplan–Meier analyses of correlations between the MIR31HG expression level and overall survival. d Subcellular locations of MIR31HG in SMMC7721 and HepG2 cells. e and f GAPDH and U6 were used as cytoplasm and nuclear localization markers, respectively
