Nobel winner says find is more than just Viagra By Nicole Foy Express-News Staff Writer Dr. Ferid Murad should be a cult god to impotent men everywhere, but he's content just knowing his medical advances helped produce one of the more successful drugs in history: Viagra. Though he remains impressed by the wild popularity and importance of the little blue pill, Murad stressed Thursday his findings in the field of nitric oxide have much broader implications. Murad, of the University of Texas Medical School in Houston, won the Nobel Prize last year for his part in the discovery that nitric oxide can relax the muscles that control the body's blood vessels. He retraced his research, which has spanned almost three decades, for colleagues of the American Society for Clinical Pharmacology and Therapeutics, which is meeting at the San Antonio Marriott Rivercenter hotel. "Initially (after the Nobel win), it was all about Viagra," he recalled in an interview after his speech. "But since then, I've tried to point out that there are situations where people are surviving because of nitric oxide. "For example, in premature intensive care units, children who are only a couple of pounds, who usually would die, are now surviving because they're given a nasal nitric oxide spray that improves pulmonary hypertension and survival rates." Murad also has been in the spotlight recently because of his decision to join 66 other Nobel Prize winners in signing a letter requesting federal funding for controversial stem cell research. Stem cells are the recently isolated human cells that continually divide, producing other cells that can develop into complete bodily organs, including a heart or liver. The research is particularly explosive because cells currently are gathered either from a developing embryo or from aborted fetuses destined for disposal. Murad defended his support of stem cell research Thursday, saying it has potential to treat many forms of human disease. "Stem cells are very important as tools in the laboratory," he said. "You can't inhibit research, but you have to use some common sense so that you don't take it in crazy directions." On the subject of the rapidly growing field of nitric oxide research, Murad is excited about the possibility of producing a host of new drugs to combat everything from cancer to heart disease. "I'm amazed at how far this has gone," he said. "We knew at the time that it is important research, but we didn't realize it was going to be this important. Still, there's a lot we don't know — a lot of opportunity lies ahead." Scientists around the globe now are studying nitric oxide and its effects. More than 20,000 articles have been published in the field since the 1970s, Murad said. The discovery that nitric oxide can alter the function of other cells represents "an entirely new principle for signaling in biological systems," the Nobel Assembly noted in granting the prize to Murad and two other Americans. Murad shared the 1998 Nobel Prize for Physiology or Medicine with Robert Furchgott, of the State University of New York in Brooklyn, and Louis Ignarro, a pharmacologist at the University of California at Los Angeles. Nitric oxide is a common gas better known as an air pollutant. It differs from nitrous oxide, also known as laughing gas. Viagra works against male impotence by using nitric oxide to relax the smooth muscle in the penis, thereby increasing blood flow to the organ. When originally discovered, the idea that any gas could regulate key functions in cells was revolutionary, Murad said. Previously known signaling agents typically were complex molecules rather than a light gas. Nitric oxide's properties allow it to pass through membranes with ease, Murad said.
