FAM193B and nonpapillary renal cell carcinoma: To identify the network of ceRNA between PVT1, miR-328-3p, and its target gene, FAM193B, in ccRCC, we collected 45 ccRCC tissues and quantified the RNA levels of PVT1 and FAM193B relative to that of GAPDH and RNA levels of miR-328-3p relative to that of U6.
