To understand the mechanism underlying praja2 downregulation in ccRCC samples, we monitored praja2 mRNA levels in Kidney Renal Clear Cell Carcinoma (KIRC, n = 533) and control (n = 72) samples using the UALCAN data-mining RNA-seq platform from TGCA repository51,52. This evidence concerns the gene PJA2 and nonpapillary renal cell carcinoma.
