Effect of MitoQ on Platelet Function and Reactive Oxygen Species (ROS) Generation in Patients With Sickle Cell Anemia
University of Pittsburgh
Summary
MitoQ is commercially available as a dietary supplement and it has been tested as a potential drug in other diseases, but it has never been tested in patients with sickle cell disease. The goal of this research is to study if MitoQ, a molecule that works as an antioxidant by removing potentially damaging agents in a living organism, improves platelet function in patients with sickle cell disease (SCD).
Description
Antioxidant therapies targeted to specific enzymes or compartments may be beneficial in sickle cell anemia (SCA). MitoQ, the most extensively studied mitochondrial-targeted antioxidant, has been shown to be protective against ischemia/reperfusion injury in the heart, endothelial damage due to hypertension and ROS in animal models. MitoQ is commercially available as a dietary supplement to reduce overall oxidative stress and anti-ageing. However, MitoQ has not been tested either as a platelet antagonist or as an endothelial protectant in SCA patients. Investigators propose to conduct a small cl…
