γH2AX expression in the gallbladder tissue of patients with and without pancreaticobiliary maljunction (PBM). Representative hematoxylin-eosin-stained images of (A) PBM tissue and (B) control tissue. Immunohistochemical staining of γ-H2AX in (C) PBM tissue and (D) control tissue. Strong staining of γ-H2AX was observed more frequently in the gallbladder epithelium of PBM cases, whereas weak staining was predominantly found in control cases. γ-H2AX, phosphorylated H2AX at Ser139 (200x magnification)
