INTRODUCTION: Endothelial cells line the inner surface of blood vessels and play a major role in modulating blood flow and gas exchange. Endothelial dysfunction is thought to be a contributor to cardiovascular disease development, and it is well-accepted that excessive reactive oxygen species (harmful molecules) likely contribute to endothelial dysfunction. The transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) is considered the master regulator of cellular protection in response to elevated reactive oxygen species. Therefore, Nrf2 may be a potential therapeutic target to protect against endothelial dysfunction. However, the roles of endothelial cell-specific Nrf2 on endothelial function are not …

Peripheral artery disease (PAD) is a manifestation of atherosclerosis in the leg arteries, which causes reduced blood flow and leg pain. This may be in part due to excessive mitochondria-produced reactive oxygen species (ROS) and attenuated mitochondrial respiratory function. Mitoquinol mesylate, a mitochondrial-targeted antioxidant, has been shown to scavenge ROS and improve vascular function in older adults and animal models. However, the impacts of mitoquinol on vascular function in PAD patients are unknown. We sought to examine the impacts of mitoquinol intake (80mg) on endothelial function (flow mediated dilation, FMD), resting heart rate (RHR), blood pressure (BP), arterial stiffness (pulse …

Impacts Of Mitoquinol Mesylate Intake On Vascular Function And Cognitive Impairment In Patients With Mild Cognitive Impairment: A Case Study, Lindie Strickler

Mild cognitive impairment (MCI) is a decline in cognitive function to a greater extent than natural aging. It has been suggested that reduced brain blood flow is strongly associated with reduced cognitive function and neurodegenerative diseases, of which is partially attributed to excessive reactive oxygen species (ROS) production. Mitoquinol mesylate has been shown to scavenge ROS and improve vascular function in healthy older adults. However, the effects of mitoquinol in MCI patients have not been investigated.

Purpose: to elucidate the impacts of mitoquinol intake on vascular endothelial function (flow-mediated dilation, FMD), arterial stiffness (pulse-wave velocity, PWV), and cognitive function in …
