ERp57 is upregulated in ccRCC tissues and correlated with poor prognosis. a ERp57 mRNA level in ccRCC (n = 35) and normal kidney (n = 35) tissues was detected by qRT-PCR. Normalized against GAPDH. *P < 0.05 vs. normal kidney tissue. b ERp57 protein level in ccRCC tissues and normal kidney tissues were detected by western blot. c Immunohistochemistry stain was used to detected ERp57 protein level in ccRCC tissues and normal kidney tissues. Scale Bar = 50 μm. d ERp57 mRNA level in ccRCC tissues and normal kidney tissues analyzed in TCGA database. d Kaplan–Meier analysis was used to analyze the overall survival of ccRCC patients with low or high ERp57 level from TCGA database (cutoff value is 25%)
