Collectively, these two transcriptomics studies identified the expression of carbonic anhydrase 9 (CA9), vascular cell adhesion molecule-1 (VCAM1), solute carrier family 17 member 3 (SLC17A3), intercellular adhesion molecule 1 (ICAM1), integrin subunit beta 8 (ITGB8), alpha kinase 2 (ALPK2), and vimentin (VIM) in ccRCC PTEC (20, 21). Here, VIM is linked to nonpapillary renal cell carcinoma.
