MMP-12 deletion attenuates HFD-induced oxidative damage in renal glomeruli.
Oxidative damage in apo E−/− and apo E−/−MMP-12−/− mice fed normal chow or HFD for 3, 6 and 9 months was assessed by detecting nitrotyrosine expression by immunohistochemistry. (B) Quantitative analysis of glomerular nitrotyrosine level expressed as a percentage of positive staining within the glomerulararea (10 glomeruli per kidney per animal). Values represent means ± SEM (n = 12 mice per group). *P < 0.05 vs. mice on normal chow; †P < 0.05 vs. mice on HFD at the same time point.
