Figure 3

Effect of corn silk (CS) extract on the expression of PCNA and Ki67 in UVB-irradiated hairless mice skin. Representative images of immunohistochemical staining of PCNA (A) and Ki-67 (B) are shown. Immunostaining of each gene is depicted as brown areas at the original magnification of ×200. PCNA (C) and Ki-67 (D) were quantified using ImageJ software. Representative Western blot image and protein levels of PCNA (E) in mouse skin tissue are shown (repeated five times). Values are mean ± SE of the percentages of positive nuclear staining in the skin tissue or protein levels. The results were analyzed by one-way ANOVA with Duncan’s post-hoc test. Bars accompanying different lowercase letters (a, b, c, d) represent statistically significant differences (p < 0.05), whereas the same letters represent no significant difference. Group abbreviations: Normal group (NOR), UVB-irradiated group (UVB), UVB-irradiated and low CS- (2 g/kg/day) treated group (CSL), UVB-irradiated and high CS- (4 g/kg/day) treated group (CSH).
