Effect of HPD on basal cell proliferation in mouse skin. Skin sections were immunostained with an antibody against BrdU and photographed at 200× magnification. Dorsal skins of mice fed (A) ND and treated with acetone, (B) ND and treated with TPA (4 μg of TPA, twice a week for 2 weeks), (C) HPD and treated with acetone, (D) HPD and treated with TPA. (E) The index represents the percentage of BrdU-positive cells relative to the total number of basal cells in the interfollicular epidermis in each experiment group. Each value represents the mean ± standard error of the labeling indices from 5 random tissue sections in each animal and 3 mice/group.

HPD, high protein diet; BrdU, 5-bromo-2′-deoxyuridine; ND, normal diet; TPA, 12-O-tetradecanoylphorbol-13-acetate.

Means with different letters are significantly different at p < 0.05 by Duncan's multiple range test. In the graph, alphabets are assigned sequentially starting from a high number to a.
