Abstract

Pancreatic cancer (PC) is an aggressive and devastating disease with a dismal prognosis. The study aimed to investigate the role of HSP90α and PDIA3 in patients with PC. Immunohistochemistry was performed on tissue microarrays containing 186 pairs of PC and normal pancreatic tissues to assess the expression levels of HSP90α and PDIA3. The expression levels of cytoplasmic HSP90α (P = 0.032) and PDIA3 (P = 0.043) in PCs were significantly higher than those in normal pancreas tissues, but nuclear HSP90α showed lower expression in PC tissues (P = 0.002). In addition, cytoplasmic expression of HSP90α and PDIA3 was significantly associated with perineural invasion (PNI) (P = 0.004) and sex (P = 0.014), respectively. These results indicate that cytoplasmic HSP90α may serve as a biomarker for PNI in PCs.
