Inhibition of RKIP transcription in ccRCC occurs to greater levels than VHL transcription based on the quantification analysis of their transcripts in six large datasets of DNA microarray available in OncomineTM with the median rank of suppression being 582 and 2343 for RKIP and VHL, respectively. This evidence concerns the gene PEBP1 and nonpapillary renal cell carcinoma.
