Enhanced expression of pluripotent c-Myc, Oct-4, and KLF-4 genes in hyperplastic dysplasia tissue. C57BL/6J mice were fed a control diet or high-fat/-calorie diet plus high fructose/glucose in drinking water (HF/C diet plus HF/G) for 12 months. (a–c) Representative micrographs and semi-quantification (d–f) of immunohistochemical staining of c-Myc, Oct-4, and KLF-4 in mouse liver at 5, 9, and 12 months. The positive signal was developed with DAB (in brown color indicated by arrow symbols). Representative images were recorded at original magnification (× 400), and scale bars=50 μm. *P<0.05 and **P<0.01 compared to mice fed control diet at corresponding time point.
