Low expression of miR-203 was found in ccRCC tissues and associated with poorer overall survival. A. The expression level of miR-203 was lower in renal caner cell lines compared with normal human proximal tubule epithelial cell line HK-2. B. The expression levels of miR-203 were significantly decreased in ccRCC tissues compared to adjacent non-tumor tissues. C. The Kaplan–Meier analysis revealed that low expression of miR-203 was associated with poorer overall survival of ccRCC patients.* P <0.05.
