FN1 and nonpapillary renal cell carcinoma: GSEA results further revealed that the SERPINH1 mRNA level was positively correlated with the EMT phenotype (Fig. S3B) and levels of mesenchymal markers [VIM, N‐Cadherin, SNAI1 and FN1], and negatively correlated with the level of epithelial marker E‐Cadherin in ccRCC (Fig. S3C).
