The goal of the experiment was to explore the differences in the proteomic landscape of pancreatic cancer tissues collected by the Rapid Autopsy Program at UNMC. We hypothesized the proteomic profile can reflect some of the clinical features observed in the patient, and such information can be used for the diagnosis of the disease, or assisting in the selection of treatment options in a clinical setting. The liver metastases tissue collected from 59 pancreatic cancer patients were used to explore the proteomic landscape. 56 of these patients were diagnosed with pancreatic ductal adenocarcinoma (PDAC) and 3 of them had pancreatic neuroendocrine tumors (PanNET). The additional 9 primary tumor samples analyzed are included in this project.
