Supplementary Figure 1. Validation of miR-10b downregulation in ccRCC compared to normal kidney tissue from the same patient. Representative bar graph showing miR-10b expression in ccRCC compared to normal counterpart from the same tissue. miR-10b was significantly downregulated in cancer compared to normal tissue (p <0.0001), in agreement with our RT-qPCR findings.
