MIR31HG inhibited cell proliferation, migration and invasion of HCC. a Proliferations of HCC cells were assessed by MTS assays after transfection with pcDNA3.1, pcDNA3.1-MIR31HG, sh-NC or sh-MIR31HG. b Clone formation assay of differently treated HCC cells. c The healing abilities of MIR31HG in SMMC7721 and HepG2 cells were determined with Wound healing assay (magnification, 50 ×; scale bar, 500 μm). d and e Quantification number of migration and invasion cells with different expression levels of MIR31HG (magnification, 200 ×; scale bar, 125 μm). (*P < 0.05, **P < 0.01 versus pcDNA3.1 group; #P < 0.05, ##P < 0.01 versus sh-NC group)
