FIG. 5.

The H2O2-mediated increase in nitrotyrosine (NT) is reduced by ebselen in the diabetic ApoE−/−GPx−/− (dKO) kidney. A–D: Representative photomicrographs of kidney tubules after 20 weeks of diabetes. (A) nondiabetic dKO, (B) diabetic dKO, (C) diabetic dKO + Eb, and (D) negative control which consisted of species-matched nonimmune IgG in place of primary antibody. E–H: Representative photomicrographs of kidney glomeruli after 20 weeks of diabetes. Nondiabetic dKO (E); Diabetic dKO (F); diabetic dKO + Eb (G); and negative control which consisted of species-matched nonimmune IgG in place of primary antibody (H). Quantitation of nitrotyrosine-stained tubules and glomeruli is shown in I and J, respectively. ***P < 0.001; diabetic dKO versus diabetic ApoE−/− kidneys. ##P < 0.01 and ###P < 0.001 vs. diabetic dKO kidneys. Bars, mean ± SEM; n = 6–8 kidneys/group. a.u., arbitrary units; D, diabetic; Eb, ebselen; ND, nondiabetic. (A high-quality digital representation of this figure is available in the online issue.)
