Fig. 3From: The opposite roles of nNOS in cardiac ischemia–reperfusion-induced injury and in ischemia preconditioning-induced cardioprotection in miceEffects of L-VNIO and MnTBAP on IR-induced TBARS and nitrotyrosine levels. a Cardiac tissue TBARS levels were measured as described in “Methods” and results are expressed as mean ± SEM. Cardiac nitrotyrosine levels were determined as described in “Methods”. b The upper band is β-actin; lower bands for nitrotyrosine from each group were shown as described in “Methods”. c Results were normalized to multiples of the result for the WT Sham group, and are expressed as mean ± SEM. White bars represent WT mice groups; black bars represent KO groups. *P < 0.05 compared with the WT Sham group, ¶P < 0.05 compared with the WT IR group, †P < 0.05 compared with the WT IR + LVNIO group, §P < 0.05 compared with the KO IR groupBack to article page
