ERRα is overexpressed and correlates with poor prognosis in PC. A. ERRα expression was determined by qRT-PCR in 50 paired PC tissues and adjacent non-tumor tissues. B. The comparisons of ERRα mRNA expression level between PC tissues and adjacent non-tumor tissues. The results were presented as log 2-fold change of tumor tissues relative to non-tumor tissues. C. Overall survival curves of PC patients stratified by ERRα expression. D. Representative images of ERRα expression in PC tissues and adjacent non-tumor tissues using IHC staining. E. The IHC staining scores of ERRα were higher in PC tissues than in adjacent non-tumor tissues. *P<0.05, **P<0.01, ***P<0.001.
