ANGPTL4 and nonpapillary renal cell carcinoma: Furthermore, our microarray analysis confirmed that the expression of VLDLR and ANGPTL4 (Supplementary Fig. S1), putative key genes for ChE and TG accumulation, was upregulated, as VLDLR and ANGPTL4 were previously shown to be expressed at higher levels in the ccRCC tissue23, 24, 25, 26.
