Other research has shown that transferrin (TF) and beta-1,4-N-acetyl-galactosaminyltransferase 1 (B4GALNT1) are highly expressed in patients with ccRCC, and B4GALNT1 may affect the occurrence and progression of renal cancer through the Hippo signaling pathway (Yang et al., 2019a). This evidence concerns the gene TF and nonpapillary renal cell carcinoma.
