TXN and exocrine pancreatic carcinoma: Figure 1 shows representative photomicrographs of different staining patterns, i.e., weak, moderate, and strong cytoplasmic and nuclear immunohistochemical staining, for specific Trx system proteins in PDAC tissue microarrays. Supplementary Figure S2 shows representative photomicrographs of staining patterns for Trx system proteins in tissue microarrays of carcinomas of the pancreas, distal bile duct, and ampulla.
