NAC feeding blocks γ-IR-induced redistribution of TJ proteins in mouse intestine. Mice were fed a liquid diet with or without 20 mM NAC for 5 days before a 4 Gy dose of TBI (IR) or sham treatment (Sham). At 2 h post-IR, cryosections of distal colon (A) and ileum (B) were stained for occludin (green) and ZO-1 (red) by the immunofluorescence method, and the nuclei were stained with Hoechst 33342 (blue).
