PVT1 and nonpapillary renal cell carcinoma: Accordingly, the expression of the lncRNAs SNHG17, PVT1, and ZMIZ1-AS1 was upregulated in ccRCC tissues compared with that in peritumoral normal tissues, and high expression of these lncRNAs (SNHG17, PVT1, and ZMIZ1-AS1) was associated with poor ccRCC patient prognosis (Fig. 8C, D).
