Down-regulation of miR-622 in RCC tissues is correlated with clinicopathological characteristics. a miR-622 expression was measured in kidney cancer cells by RT-PCR. b The RCC cells and HK-2 cell invasion was assayed by transwell system. All the cells were transfected with miR-622 mimics and its control for 24 h and then seeded in the up-chamber with matrigel treatment. The cell invaded cells were counted under the microscope. c miR-622 expression was measured in RCC tissues by RT-PCR. d miR-622 expression in high metastasis (n = 78) and low metastasis (n = 34) of RCC. **P < 0.01; *P < 0.05
