Effect of a high-fat diet in development of colonic adenoma in an animal model

Figure 6 Western blot analyses for proliferating cell nuclear antigen, cyclin D1, nuclear factor-kappa B and β-catenin. A: Representative Western blotting images are shown in the left panel (n = 8/group); B: Right panel: graphs showing the expression ratio of each protein over β-actin in the high-fat diet (HFD) group compared with the normal-fat diet (ND) group. ^bP < 0.01, ^dP < 0.01, HFD group vs ND group. PCNA: Proliferating cell nuclear antigen; NF-κB: Nuclear factor-kappa B.
