PPP2R2D and nonpapillary renal cell carcinoma: Similar analysis with genes associated with loci that showed hypomethylatation upon VHL expression in cell lines and hypermethylatation in ccRCC tumors returned only 3 genes whose expression showed negative correlation to the CpG methylation; HOXB8, FAM89A and PPP2R2D, of which none were among the HIF-target genes.
