Figure 3From: Brain region specific mitophagy capacity could contribute to selective neuronal vulnerability in Parkinson's disease Immunostaining of protein carbonyl moieties revealed significantly lower amount of oxidized proteins in cortex tissue than in striatum and midbrain in both PINK1-KO and wild type mice (ANOVA analysis followed by unpaired Student T-test, p < 0.05). A) A representative Oxyblot image of a 2DE gel immunostained against protein carbonyls (image from PINK1-KO, midbrain). B) Bar chart showing differential protein oxidation extents in striatum, midbrain and cortex tissues of PINK1-KO and control mice (mean ± SEM, n = 3. see Materials and Methods for detail). Hereby, the average signal intensity of protein oxidation in striatum of control mice was set as 100%. Experiments were repeated three times on exactly 100 μg of pooled protein extract of each brain region.Back to article page
