In an attempt to elucidate this possibility in ccRCC, we performed miRNA (OneArray® v7, Phalanx Biotech Group) and cDNA microarray analyses (Affymetrix human U133 2.0 plus) on Caki-1/shCtrl and Caki-1/shKSRP cells to explore potential miRNAs and genes regulated by KSRP (Fig. 2A). Here, KHSRP is linked to nonpapillary renal cell carcinoma.
