To further investigate the expression profile of IFI16 in human ccRCC, we detected IFI16 expression in four human ccRCC cell lines (i.e., SW839, OSRC-2, SM12-PN6, Caki-1, and 786-O) and found that the mRNA levels of IFI16 was relatively higher in most of the ccRCC cells (Figure 10C). This evidence concerns the gene IFI16 and nonpapillary renal cell carcinoma.
