In order to further evaluate the expression of PDIA3 protein level, the IHC results in HPA database were analyzed, which was compared with the results of differential expression analysis of PDIA3 between tumor tissues and normal tissues in TCGA database, as shown in (Figures 2(a)–2(h)), the results for other cancers are shown in Supplementary Figures s1. This evidence concerns the gene PDIA3 and cancer.
