Compared with the RPTEC, the UCA1 expression was increased remarkably in both renal cancer cells, 786-O (P < 0.001) and Caki-1 (P = 0.002) (Fig. 1g),and the miR-182-5p expression was significantly decrease in both renal cancer cells, 786-O (P = 0.010) and Caki-1 (P = 0.017) (Fig. 1h). This evidence concerns the gene UCA1 and renal carcinoma.
