Deregulated expression of miRNAs is related to progression and initiation of human cancers. Although miR-495 has identified in various tumors, its expression and function in renal cell carcinoma (RCC) is still unknown. In this study, we found that the expression of miR-495 was downregulated in RCC cell lines and tissues. Ectopic expression of miR-495 induced G0/G1 phase arrest and suppressed cell proliferation and migration in RCC cell lines. We further validated SATB1 was a direct target of miR-495 in RCC. In addition, re-expression of SATB1 reversed the miR-495-induced inhibition of cell proliferation and migration. These data suggest that miR-495 functions as a tumor suppressor and may be a promising therapeutic target in RCC in the future.
