RHOB and nonpapillary renal cell carcinoma: The relative expression of miR-19a,miR-19b and RhoB in paried specimens individually showed in the supplementary information.(S1 Fig).The mRNA levels of miR-19a and miR-19b in ccRCC cell lines were also dramatically inversely correlated to RhoB expression among normal renal cells (HK2 and HKC) and ccRCC cell lines (A498, Caki-2, 786-O, ACHN, Caki-1, and SN12) (Fig 1D).
