Fig. 6From: A prospective study on histone γ-H2AX and 53BP1 foci expression in rectal carcinoma patients: correlation with radiation therapy-induced outcomeCorrelation between the γ-H2AX foci expression and tumor regression grade (TRG). DNA damage assessed by means of the γ-H2AX foci expression in non-irradiated and irradiated peripheral lymphocytes of RC patients with different tumor regression grade (TRG, Additional file 1: Table S2). Up and down triangles show γ-H2AX foci amounts in the cells of RC patients with TRG 0–2 and TRG 3–4, respectively. Filled squares represent the mean values (± SE) for the respective group. “n.s.” indicates that the difference was not highly significant (p > 0.05)Back to article page
