| Research Abstract |
The present study aimed to identify novel useful clinical biomarker at early stages and to elucidate the molecular background of carcinogenesis in human pancreatic ductal adenocarcinomas (PDACs). Proteomes of dissected PDACs and adjacent non-tumor pancreatic tissues from formalin-fixed and paraffin-embedded sections from 10 patients were analyzed using QSTAR Elite LC-MS/MS, ProteinPilot and Ingenuity Pathway Analysis (IPA). Expression of potential biomarker candidates was validated immunohistochemically in 50 PDAC patients, following by survival analyses and statistical comparison of protein expression with clinicopathological variables.
Paraneoplastic Ma antigen-like 1 (PNMAL1) was selected as a potential biomarker. Immunohistochemical evaluation in 50 PDAC patients revealed that its positive expression was significantly associated with the better overall survival (log-rank test; p=0.009). thus, PNMAL1 is suggested as a novel potential clinically useful prognostic biomarker of PDAC.
