Moreover, as shown in Fig. 1K, SLC27A3 is mainly highly expressed in lipid-enriched tumors such as ccRCC and glioblastoma, while the expression of SLC27A3 did not increase or even decrease in other tumors such as breast cancer and lung cancer, indicating that SLC27A3 is certain lipid tumor specific, which is the main feature that distinguishes it from other oncogenes in ccRCC. This evidence concerns the gene SLC27A3 and nonpapillary renal cell carcinoma.
