miR-22 is down-expressed in HCC tissues and cell lines. a Analysis of the expression pattern of miR-22 in non-metastasis tumors and metastasis tumors of HCC correlated with adjacent non-tumor tissues using real-time RT-PCR. b The relative levels of miR-22 in the seven HCC and three normal liver cell lines. Student’s t test was used to analyze the significant differences, *P < 0.05, **P < 0.01
