The aim of this study was to evaluate the expression profile and textural characteristics of C595-reactive MUC1 in PDAC cell lines, PDAC tissues, normal pancreas, pancreatitis and the PDAC precursor lesions, pancreatic intra-epithelial neoplasia (PanIN), to establish the feasibility of C595-based TRT for PDAC. The gene discussed is MUC1; the disease is pancreatitis.
