Therapeutic effects of Zn on renal remodeling, inflammation, and oxidative damage in OVE26 type 1 diabetes mice. Renal structural changes were examined with (A) H&E and (B) Sirius red staining. Renal expression of TGF-β1 and CTGF, as indices of profibrotic mediators, was examined by (C) Western blot and (D) immunohistochemical staining. Renal expression of TNF-α, ICAM-1, and PAI-1, as indices of inflammation, and 4-HNE, as an index of lipid oxidation, was also detected by (E) Western blot assay and (F) immunohistochemical staining. Data are presented as the mean ± SD (n = 6). *p < 0.05 vs control (Ctrl); #p < 0.05 vs DM group. Bar, 50 μm.
