Figure 7. Collagen type IV expression in the glomeruli of the four groups after 4 weeks of dietary treatment.

(A) Representative immunohistochemistry for collagen type IV in glomeruli. Scale bar = 50 μm. (B) Bar graph summarizing collagen type IV expression in glomeruli. Each bar represents the mean ± SEM; n = 4 in each group. *P < 0.001. Two-way ANOVA, gene, p < 0.001; diet, p < 0.001; gene × diet, p < 0.001.
