As shown in Figure 2, IHC data obtained from the public database HPA [16] gave us a direct visual result that FBP10 and PLOD2 displayed a strongly stained pattern in ccRCC tissues (Figure 2A, 2B), in contrast, normal kidney tissues have a relatively low level of FKBP10 and PLOD2 (Figure 2C, 2D). This evidence concerns the gene FKBP10 and nonpapillary renal cell carcinoma.
