Abstract
Objective: In Parkinson's disease (PD), mitochondrial defects and oxidative stress cause an increase in free radicals and the death of dopaminergic neurons in the substantia nigra. By preventing lipid peroxidation and protecting against peroxide radicals, vitamin E is the most important antioxidant of biological membranes that can neutralize free radicals. Also, the improvement of the functional status of mitochondria can be influenced by exercise, which can be partially the result of changes in the mitochondrial mitophagy and dynamics system. This study aimed to investigate the interactive effects of six weeks of vitamin E (VE) consumption and training on the mitochondrial function [Cytochrome C (Cyt-C), Adenosine triphosphate (Atp) synthase, optical atrophy1 mitochondrial dynamics like guanosine triphosphatase (GTPase), 8-Oxodequanosin and Pten induced kinase 1 (Pink1) is a protein coding gene] in the hippocampus tissue of PD rats.
Materials and methods: In this experimental study, 4-6-month-old Sprague-Dawley rats (mean weight 250 ± 30 g) were given parkinsonism with reserpine (2 mg/kg) and were categorized into different groups, including healthy (H), PD, VE solvent+PD (Sham), aerobic exercise+PD (AE+PD), VE+PD, AE+VE+PD. The aerobic training program was carried out for six weeks and 5 sessions per week and each session lasted 15-22 minutes. VE was also taken orally at 30 mg/kg daily.
Results: A six-week regimen of VE supplement along with the AE significantly reduced the Cyt-C gene expression level, also we observed a significant increase in gene expression level of the Pink1, Atp synthase and Opa1 (P<0.05). There is no significant difference was found in the level of 8-Oxog detected in hippocampal tissue samples (P>0.05).
Conclusion: The consumption of VE along with AE may provide therapeutic effects on mitochondrial damage in PD rats.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
