| Outline of Final Research Achievements |
The aim of this study was to identify novel liver metastasis-correlated proteins of pancreatic neuroendocrine neoplasm (PanNEN). Proteomic analysis was performed in resected specimens of pancreatic tumor and paired liver metastasis. ANXA6, CNPY2, RAB11B, and TUBB3, which showed higher expression in liver metastasis than in pancreatic tumor, were selected as candidate proteins. Expression of these candidate proteins was examined in pancreatic tumors of 70 patients with PanNEN by immunohistochemistry. Correlation between clinicopathological factors and expression of the candidate proteins was statistically analyzed. It was revealed that CNPY2 is a novel liver metastasis correlated protein of PanNEN.
