Studies assessing fatty acid synthase [9,10], enoyl-CoA hydratase short-chain 1 (ECHS1) [11], HDL-Receptor SR-BI [12], the lipid transporter CD36 [13], FA catabolic enzymes [10,14] or the fatty acid transport protein 4 [15] suggest that these genes regulate ccRCC tumor growth and can predict patient survival. This evidence concerns the gene SLC27A4 and nonpapillary renal cell carcinoma.
