Research
Our laboratory studies nitric oxide (NO) biosynthesis in mammals. NO is made by an enzyme named NO synthase, and is involved in many aspects of cell function and disease, including signal transduction in the brain, control of blood pressure and heart rate, gastric motility, oxygen delivery, immunologic destruction of tumor cells and microbes, infertility, impotence, and stroke. We study how NO biosynthesis takes place at the molecular level and how it is regulated, and also study the impact of NO synthesis on certain aspects of cells and tissues. Our interests include the NO synthase enzyme chemistry, understanding how the enzyme’s protein structure relates to its function, and learning how other cellular proteins can interact with NO synthase to control its activity. We are also studying how NO regulates heme insertion into cellular proteins, and how protein nitration, which is a downstream consequence of NO production, takes place in cells, is regulated, and how it may control protein functions in cells and tissues.

Careers
Research News
Cleveland Clinic researchers discover connections between nitric oxide and heme proteins in regulating critical cellular and tissue signaling and physiological functions.
Dennis Stuehr, PhD, Department of Inflammation & Immunity, was awarded a four-year, $1.9 million grant from the National Institute of General Medical Sciences to investigate how hemeproteins contribute to critical biological processes and may be associated with a broad number of clinically relevant diseases, including asthma, autoimmune disorders, bacterial infections and more.
Joining a list of highly regarded researchers honored, Dr. Stuehr is the first Cleveland Clinic scientist to receive the award.
A protein called hsp90 (heat shock protein 90) is essential in forming functional, mature Hb that successfully delivers oxygen to cells throughout the body.
