PVT1 and nonpapillary renal cell carcinoma: To determine whether miR-328-3p and/or miR-3127-5p are the target miRNAs of PVT1 for its regulation of tumor cell proliferation, we investigated the levels of miR-328-3p as well as miR-3127-5p in tissues of ccRCC and adjacent normal parts from 45 patients.
