简介
Mitochondrial dysfunction and oxidative stress contribute to the neuropathology of neurodegenerative disorders such as Parkinson's disease (PD). Paraoxonase-2 (PON2) is a mitochondrial protein that mitigates oxidative stress, enhances mitochondrial function and exhibits anti-inflammatory properties. Previously, we have documented sex-based variation in PON2 with higher brain PON2 expression in female (2-fold) as compared to male African green monkeys. This aim of this study is to identify PON2 isoforms and explore the region-based variations in the protein level of PON2 in brain of African green monkeys. Male and female brain tissue samples (striatum, hippocampus, occipital cortex, dorsolateral prefrontal cortex) from African green monkeys (Chlorocebus sabaeus) were analyzed by western blotting technique for PON2 expression. We found two PON2 isoforms (39 and 41 kDa) in each examined brain …
