Figure 3. The expression levels of KRT16 protein in paired tumor and benign pancreatic tissues from patients who underwent resection for PDAC.

Upper panels: immunohistochemistry images: (A) and (B), KRT16 expression in normal pancreatic tissues; (C) and (D), KRT16 expression in PDAC. Magnification was x40 for panel (A) and (C) and x100 for panel (B) and (D). Lower pane: KRT16 staining scores in PDAC (T) and benign pancreatic tissues (N).
