  1. *To be considered as expressed, a probe signal should be detected above the median array intensity value in at least 75% of samples from at least one histological type.
  2. NT, non-tumor pancreatic tissue; T, primary pancreatic adenocarcinoma; M, metastases from primary pancreatic tumors; CP; chronic pancreatitis.
