Let-7b overexpression inhibited the tumorigenesis potential of HCC cells. aThe tumorigenicity of HepG2 cells transfected with let-7b mimics was detected. Pictures were taken at different times after subcutaneous injection. b Quantitative analysis of tumor volume in each group. Data from three replicates are shown as the means (± SD). **P < 0.01, ***P < 0.001. c Immunohistochemical staining was employed to detect the expression of Ki67 in HCC tissues. d The expression of Ki67 in HCC tissues was evaluated and the data was measured by IOD
