To confirm the actual expression level of RNASET2 in cancer tissues obtained from the ccRCC patients in our affiliated hospital, real‐time quantitative RT‐PCR and western blot analyses were applied, respectively, to detect both the RNASET2 mRNA expression levels and their corresponding protein contents in ccRCC tissues. The gene discussed is RNASET2; the disease is nonpapillary renal cell carcinoma.
