Furthermore, genes previously associated with ccRCC susceptibility or carcinogenesis, apolipoprotein C-I (APOC1), vascular endothelial growth factor A (VEGFA), scavenger receptor class B, member 1 (SCARB1) were found to be highly overexpressed in tumour tissue in both analysis. This evidence concerns the gene APOC1 and nonpapillary renal cell carcinoma.
