The Chemical Biology of Nitric Oxide
Getting to K(NO)w a Radical
Senior Staff Fellow, National Cancer Institute
About the Lecture
The diatomic radical nitric oxide (NO) long has been associated with the deleterious effects of air pollution and cigarette smoke. However, over the course of the last decade, this small molecule was found to have important roles in almost every tissue in the body. These discoveries have sparked the growth of one of the largest fields in biomedical research. The roles of NO in biology range from regulation of cardiovascular function and neurotransmission to participation in the etiology of a wide variety of diseases such cancer and stroke. This dichotomy has made NO the Dr. Jekyll and Mr. Hyde of the bioscience world. Understanding the myriad of biological effects of NO is complicated by its diverse chemistry. The "chemical biology of NO" places the relevant chemistry of NO in contexts that can be used to readily decipher the underlying role this molecule plays in a variety of diseases as well as provides insights into possible therapeutic strategies.
