NEDD4L and nonpapillary renal cell carcinoma: We then verified correlations of KSRP or NEDD4L with EMT-related genes in human ccRCC samples using the cBioPortal platform and observed that KSRP and NEDD4L expressions were respectively positively and negatively correlated with expressions of the mesenchymal markers of N-cadherin (CDH2), vimentin (VIM), Snail (SNAI1), and Slug (SNAI2) (Fig. 3F).
