Summary
Excessive production of free radicals by an enzyme called Nox2 may be a cause of artery disease leading to heart attacks and strokes. This study will identify whether the addition of sugarchains to Nox2 causes it to be expressed at the surface of cells allowing the free radicals it produces to exit the cell and cause damage to the blood vessel wall. Charaterising this new pathway of excessive free radical production may pave the way for new diagnostics and treatments for artery disease.
Heme-oxidised Soluble Guanylyl Cyclase, A Mechanism-based Target For Vascular Diagnostics And Vasoprotective Therapy

Summary
Nitric oxide is produced in the inner lining of blood vessels and maintains blood flow via binding to a specific protein, sGC. In disease, sGC is defective and can be targeted by a novel group of drugs which are more active in diseased versus normal blood vessels. This project will examine the use of these drugs as markers of cardiovascular disease and in the treatment of high cholesterol and may lead to the development of new diagnostic tools and therapies for vascular complications.
