The results of RT-qPCR showed that the expression level of SNHG19 in ccRCC cell lines (786-O, CAKI, RCC-JF) was remarkably higher than that in the renal tubular epithelial cell line (HK2).786-O cell was chosen for subsequent research, in which SNHG19 is the most highly expressed (Fig. 1A). Here, SNHG19 is linked to nonpapillary renal cell carcinoma.
