Applying proteomics and IHC, we also detected increased abundance of protein of AXL, and VIM, in ccRCC, and decreased abundance of CDH1, thereby supporting RNA sequencing data, as depicted in Figure 6A and B. In addition, Figure 6A indicates that there could be some stromal cells detectable next to CDH1‐positive tubules, which may explain in part the relatively high EMT values of some carcinoma‐adjacent normal kidney samples (Fig. 1). This evidence concerns the gene CDH1 and nonpapillary renal cell carcinoma.
