PDIA3 and cancer: Though no significant difference was found between the median Axiotis score of cancer tissues, adjacent tissues and distal tissues (10.725 ± 2.325 versus 10.45 ± 1.45 versus 10.25 ± 1.36), respectively, their ERp57 expression was significantly higher compared to normal liver tissues (4.375 ± 2.84) (Figure 1).
