γ-H2AX expression in cancerous and non-cancerous areas of gallbladder tissue in patients with pancreatobiliary maljunction (PBM). Representative hematoxylin and eosin-stained images of the (A) non-cancerous area and (B) cancerous area. Immunohistochemical staining of γ-H2AX in the (C) non-cancerous area and (D) cancerous area. The cancerous area appeared to have stronger and more diffuse staining than the adjacent non-cancerous area. γ-H2AX, phosphorylated H2AX at Ser139 (200x magnification)
