Representative immunohistochemical staining for RGC-32(A-C) and E-cadherin (D-F) in pancreatic cancer, chronic pancreatitis and normal pancreas tissues (original magnification × 200). (A) RGC-32 highly positive staining in pancreatic cancer tissues (B) RGC-32 positive staining in chronic pancreatitis tissues (C) RGC-32 slightly positive staining in normal pancreas tissues (D) normal membranous E-cadherin staining (membranous pattern) in pancreatic cancer tissues (E) cytoplasmic staining with loss of membranous expression (cytoplasmic pattern) in pancreatic cancer tissues (F) loss of E-cadherin staining (absent pattern) in pancreatic cancer tissues.
