γH2AX positivity correlates with extent of chronic inflammation. (A) Tissues were classified according to extent of chronic inflammatory cell infiltration as positive (n=6) or negative (n=3) and subjected to multiplex immunohistochemistry staining with antibodies against EpCAM/pan-Cytokeratin (CK), MCM2 and γH2AX. Immunofluorescence images of MCM2 or γH2AX with EpCAM/pan-Cytokeratin (CK) are shown. Scoring map depicts epithelial cells positive for γH2AX (magenta), MCM2 (green), γH2AX /MCM2 double-positive (DP) (red) and γH2AX/MCM2 double-negative (grey). (B) Plot shows percent MCM2 positivity in the chronic inflammation positive and negative groups. (C) Plot shows percent γH2AX positivity in the chronic inflammation positive and negative groups. Line within the vertical scatter plot shows the mean value. Error bar shows ±SD. Statistical significance was analysed by the Mann-Whitney non-parametric test. * p<0.05, n.s-not significant.
