Conclusion
Oral CoQ10 decreases blood pressure by negatively regulating fructose-induced NADPH oxidase levels, abolishing ROS generation, reducing p38 phosphorylation, and enhancing the Akt-nNOS pathway in the NTS. These results support the beneficial effects of CoQ10 in oxidative stressassociated hypertension.
Results
Treatment with oral CoQ10 for 4 weeks abolished nicotinamide adenine dinucleotide phosphate-oxidase (NADPH oxidase) activation, decreased p38 phosphorylation, and increased superoxide dismutase 2 production in the NTS of fructose-fed rats. The serum levels of uric acid decrease in response to CoQ10 treatment in fructose-fed rats. Oral CoQ10 reduced blood pressure by inducing Akt and nNOS phosphorylation in NTS of fructose-induced hypertensive rats.
