We randomly selected five clinical samples and removed one sample that did not express TNFAIP8 and found that the relative expression levels of E-cadherin and ZO-1 in the ccRCC group were decreased compared with that of the adjacent normal groups (Figure 5A, C), but N-cadherin and vimentin were increased in the ccRCC group (Figure 5B, D). Here, VIM is linked to nonpapillary renal cell carcinoma.
