STOCKHOLM, Sweden -- Americans Andrew Z. Fire and Craig C. Mello won the Nobel Prize in physiology or medicine Monday for discovering a powerful way to turn off the effect of specific genes, opening a new avenue for disease treatment.

"RNA interference" is already being widely used in basic science as a method to study the function of genes and it is being studied as a treatment for infections such as the AIDS and hepatitis viruses and for other conditions, including heart disease and cancer.

Fire, 47, of Stanford University, and Mello, of the University of Massachusetts Medical School in Worcester, published their seminal work in 1998.

RNA interference occurs naturally in plants, animals, and humans. The Karolinska Institute in Stockholm, which awarded the prize, said it is important for regulating the activity of genes and helps defend against viral infection.

"This year's Nobel laureates have discovered a fundamental mechanism for controlling the flow of genetic information," the institute said.

Erna Moller, a member of the Nobel committee, said their research helped shed new light on a complicated process that had confused researchers for years.

"It was like opening the blinds in the morning," she said. "Suddenly you can see everything clearly."

Genes produce their effect by sending molecules called messenger RNA to the protein-making machinery of a cell. In RNA interference, certain molecules trigger the destruction of RNA from a particular gene, so that no protein is produced. Thus the gene is effectively silenced.

For instance, a gene causing high blood cholesterol levels was recently shown to be silenced in animals through RNA interference.

Mello, reached at his home in Shrewsbury, Mass., said the award came as a "big surprise."

"I knew it was a possibility, but I didn't really expect it for perhaps a few more years. Both Andrew and I are fairly young, 40 or so, and it's only been about eight years since the discovery."

He said he would try to get into work Monday but expected to accomplish "not a lot."

Fire, who conducted the research while at the Carnegie Institution, said he was honored that the work "has received such positive attention."

"Science is a group effort. Please recognize that the recent progress in the field of RNA-based gene silencing has involved original scientific inquiry from research groups around the world," he said in a statement released by the Washington-based Carnegie Institution.

The announcement opened this year's series of prize announcements. It will be followed by Nobel prizes for physics, chemistry, literature, peace and economics.

Last year's medicine prize went to Australians Barry J. Marshall and Robin Warren for discovering that bacteria, not stress, causes ulcers.

The Nobel committees do not reveal who has been nominated for the awards, but that does not stop experts and Nobel-watchers from speculating on potential winners.

Alfred Nobel, the Swedish inventor of dynamite, established the prizes in his will in the categories of literature, peace, medicine, physics and chemistry. The economics prize is technically not a Nobel but a 1968 creation of Sweden's central bank.

Winners receive a check of $1.4 million, handshakes with Scandinavian royalty, and a banquet on Dec. 10 _ the anniversary of Nobel's death in 1896. All prizes are handed out in Stockholm except for the peace prize, which is presented in Oslo.

Americans Win Nobel Prize in Physics

STOCKHOLM, Sweden -- Americans John C. Mather and George F. Smoot won the 2006 Nobel Prize in physics on Tuesday for work that helped cement the big-bang theory of the universe and deepen understanding of the origin of galaxies and stars.

Mather, 60, works at the NASA Goddard Space Flight Center in Greenbelt, Md., and Smoot, 61, works at the Lawrence Berkeley National Laboratory in Berkeley, Calif.

The scientists discovered the nature of "blackbody radiation," cosmic background radiation believed to stem from the "big bang," when the universe was born.

"They have not proven the big-bang theory but they give it very strong support," said Per Carlson, chairman of the Nobel committee for physics.

"It is one of the greatest discoveries of the century. I would call it the greatest. It increases our knowledge of our place in the universe."

Their work was based on measurements done with the help of NASA's COBE satellite launched in 1989. They were able to observe the universe in its early stages about 380,000 years after it was born. Ripples in the light they detected also helped demonstrate how galaxies came together over time.

"The COBE results provided increased support for the big-bang scenario for the origin of the Universe, as this is the only scenario that predicts the kind of cosmic microwave background radiation measured by COBE," the Royal Swedish Academy of Sciences in Stockholm said in its citation.

The big-bang theory states that the universe was born billions of years ago from a rapidly expanding dense and incredibly hot state.

Reached at his home in Berkeley, Smoot told The Associated Press he was surprised when he got the call from the Nobel committee in the middle of the night.

"I was surprised that they even knew my number. After the discovery I got so many calls I unlisted it," he said.

"The discovery was sort of fabulous. It was an incredible milestone. Now this is a great honor and recognition. It's amazing," he said.

Mather said he was "thrilled and amazed" at receiving the prize.

"I can't say I was completely surprised, because people have said we should be awarded, but this is just such a rare and special honor," Mather said in a telephone interview with the Nobel committee.

He said he and Smoot did not realize how important their work was at the time of their discovery.

The COBE project gave strong support for the big-bang theory because it is the only scenario that predicts the kind of cosmic microwave radiation measured by the satellite.

The academy called Mather the driving force behind the COBE project while Smoot was responsible for measuring small variations in the temperature of the radiation.

With their findings, the scientists transformed the study of the early universe from a largely theoretical pursuit into a new era of direct observation and measurement.

"The very detailed observations that the laureates have carried out from the COBE satellite have played a major role in the development of modern cosmology into a precise science," the academy said.

Phillip F. Schewe, a spokesman for the American Institute of Physics, said he had expected the two to win the honor.

"It's just a really really difficult experimental measurement to make. "It's the farthest out we can see in the universe and it's the farthest back in time," he said in a telephone interview.

Since 1986, Americans have either won or shared the physics prize with people from other countries 15 times.

Last year, Americans John L. Hall and Roy J. Glauber and German Theodor W. Haensch won the prize for work that could improve long-distance communication and navigation.

This year's award announcements began Monday with the Nobel Prize in medicine going to Americans Andrew Z. Fire and Craig C. Mello for discovering a powerful way to turn off the effect of specific genes, offering new hope for fighting diseases as diverse as cancer and AIDS.

The winner of the Nobel Prize in chemistry will be named Wednesday. The Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel will be announced Oct. 9.

The winner of the peace prize _ the only one not awarded in Sweden _ will be announced Oct. 13 in Oslo, Norway.

A date for the literature prize has not yet been set.

Alfred Nobel, the wealthy Swedish industrialist and inventor of dynamite who endowed the prizes, left only vague guidelines for the selection committee.

In his will, he said the prize should be given to those who "shall have conferred the greatest benefit on mankind" and "shall have made the most important discovery or invention within the field of physics."

The prizes, which include a $1.4 million check, a gold medal and a diploma, are presented on Dec. 10, the anniversary of Nobel's death in 1896.

Good year for Stanford. Congrats to Kornberg for his Nobel in chemistry! Like father, like son.

10/04/06 News Release

STANFORD, Calif. (updated 9:15 a.m.) — The Royal Swedish Academy of Sciences today awarded Roger Kornberg, PhD, of the Stanford University School of Medicine, the 2006 Nobel Prize in Chemistry for his work in understanding how DNA is converted into RNA, a process known as transcription.

In 2001 Kornberg published the first molecular snapshot of the protein machinery responsible — RNA polymerase — in action. The finding helped explain how cells express all the information in the human genome, and how that expression sometimes goes awry, leading to cancer, birth defects and other disorders.

“I’m simply stunned. There are no other words,” said Kornberg, a professor of structural biology, this morning after the 2:30 a.m. call. “It’s such astonishing news.” The scene at Kornberg’s house was one of controlled chaos, with nonstop telephone calls from well wishers and media.

Kornberg, who is also the Mrs. George A. Winzer Professor in Medicine, is the School of Medicine's second Nobel Prize winner this week. On Monday, Andrew Fire, PhD, professor of pathology and of genetics, was a winner of the 2006 Nobel Prize in Physiology or Medicine for his work on RNA interference. Together the two awards serve as a clarion announcement of RNA’s arrival in the scientific and medical spotlight.

“Roger has been one of my role models for many years,” said Fire. “We did our post-docs at Cambridge in the same institute, and he’s been a tremendous help to me since I came to Stanford in 2003. Our fields are interestingly intertwined.”

Kornberg’s research, and latest award, is a family affair: his father Arthur Kornberg, PhD, was awarded the Nobel Prize in Physiology or Medicine in 1959 for studies of how genetic information is transferred from one DNA molecule to another. The Kornbergs are the sixth father-son team to win Nobel Prizes, in addition to one father-daughter team.

“I have felt for some time that he richly deserved it,” said the elder Kornberg after hearing about his son’s award. “His work has been awesome.” Arthur Kornberg is the Emma Pfeiffer Merner Professor of Biochemistry, Emeritus, at the School of Medicine. He learned of the award from a nephew in LaJolla, Calif., who had been called accidentally by someone looking for Roger.

“Roger Kornberg is one of our nation’s treasured scientists,” said Philip Pizzo, MD, dean of the School of Medicine. “He has dedicated his life and career to using the powerful tools of structural biology to elucidate the molecular mechanism of transcription. His remarkable studies have been acclaimed for the elegance and technical sophistication as well as the unique insights they have yielded. His work has deepened our understanding of the ‘message of life’ and how it contributes to both normal and abnormal human development, health and disease.”

Kornberg emphasized that the work required many contributions. “I am indebted to my colleagues,” he said. “This is not something that I did alone, or even with a small number of people. It is the result of the hard work, insight and inspiration of very many exceptionally talented Stanford students and post-docs.”

Selective transcription of a cell’s tens of thousands of genes determines whether it becomes a neuron, a liver cell or a stem cell — and whether it develops normally or becomes a runaway cancer. The picture of RNA polymerase at work provided an atomic-level window into how the protein complex unzips and then re-zips the double-stranded DNA like a Ziploc bag after using the internal code to build a specific RNA molecule. It was a thing of beauty for biologists around the world.

“We were astonished by the intricacy of the complex, the elegance of the architecture, and the way that such an extraordinary machine evolved to accomplish these important purpose,” said Kornberg of the images he and his colleagues created. “RNA polymerase gives a voice to genetic information that, on its own, is silent.” Learning how that voice is amplified — and shushed — through the selective expression of genes is a critical stepping stone to many areas of biological and medical research.

The path to the pictures involved a highly specialized field at the intersection of chemistry, biology and physics called crystallography. The technique, as much art as science, is the same one used by Francis Crick and James Watson to determine the double-stranded nature of DNA. In general, it involves evaporating a concentrated solution of a molecule until all that’s left are highly structured crystals somewhat like the crust of salt left behind by drying seawater. Extremely bright X-rays are then able to pinpoint the position of individual atoms and the data are used to produce a computer-generated representation of the molecule.

Successfully crystallizing one molecule is a feat worth congratulating. Capturing the 10 subunits of RNA polymerase in action on the DNA was unthinkable.

“It was a technical tour de force that took about 20 years of work to accomplish,” said Joseph Puglisi, PhD, professor and chair of the department of structural biology at the School of Medicine. “Like other great scientists, Roger doesn’t quit. He’s stubborn. A lot of scientists would have given up after five years.” Kornberg’s determination, couple with his expertise in both crystallography and biochemistry, finally cracked the code.”

“I'm a biochemist and he’s a biochemist, but beyond that he’s a crystallographer, a structural chemist and a geneticist,” said Arthur Kornberg. Roger Kornberg devised a way to first initiate the process of transcription in a test tube and then stall it by withholding one of the building blocks of RNA. Crystallizing the frozen complex showed the relative positions of the polymerase, the DNA template and the growing RNA strand.

“Professor Kornberg’s seminal research on transcription has been an exceptional contribution to the body of knowledge in fundamental biology,” said Stanford University President John Hennessy. “His work settled long-open questions about how genes communicate the information needed to make proteins and will help us understand a variety of diseases that can be caused by a failure in the transcription process. For the second time this week, a colleague’s achievement reminds us of the unique role universities have in advancing basic knowledge. We are proud to claim Professor Kornberg and his father Arthur as members of the Stanford family. I offer Roger warm congratulations on behalf of the entire university community.”

Prior to beginning his work studying the molecular mechanism of transcription, Kornberg discovered the nucleosome, the basic unit from which all chromosomes are made. In 1974, as a junior scientist at Cambridge University, he proposed that the massive amounts of DNA contained in every cell could be compactly stored by wrapping it in its condensed form—the chromosome—around eight histone protein “spools” to form nucleosome “beads.” Kornberg and his wife and collaborator Yahli Lorch, PhD, associate professor of structural biology at Stanford, were instrumental in identifying the nucleosome as fundamental to transcription. Since then, it has been recognized that disruptions involving the nucleosome underlie many cancers and other diseases.

Born in 1947, Kornberg was the first of three children born to Arthur Kornberg and his wife, Sylvy, who was also a biochemist working with Arthur.

“Roger was a scientist from the beginning; He never showed any other interest,” said his brother, Thomas Kornberg, PhD, a professor of biochemistry at the University of California-San Francisco.

“Both my parents had fine scientific minds and taught by example how to approach questions and problems in a logical, dispassionate way,” Kornberg once said. “Science was a part of dinner conversation and an activity in the afternoons and on weekends. Scientific reasoning became second nature. Above all, the joy of science became evident to my brothers and me.” Kornberg was able to indulge his scientific bent early as a high school student working in the laboratory of Paul Berg, a colleague of his father’s at Stanford who won the Nobel Prize in Chemistry in 1980.

The senior Kornberg said his son’s winning did not come entirely out of the blue. He had mentioned the chemistry prize yesterday in a conversation with his son, who had just returned from a trip to Jerusalem. “I talked to him at length and couldn’t help but discuss this possibility — I know he’s been shortlisted in previous years,” said the elder Kornberg. “He dismissed it, saying it was a possibility but he didn’t expect it, but that’s the way it goes.”

Arthur Kornberg said he had not imagined decades ago, when his son first began his career as a biochemist, that there would be a second Nobel laureate in the family. “Of course not,” he remarked. “But nature is so broad, profound and mysterious — one doesn’t know where it leads. And I would say among the people I know — and I have trained many hundreds — he has the clearest vision, sense of purpose and direction.”

Pizzo paid tribute to the contributions of both father and son to Stanford. “Arthur Kornberg played a major role in transforming the Stanford University School of Medicine to a research-intensive powerhouse,” Pizzo said. “He was clearly productive in both his professional life and his private life—since he is the father of remarkably talented children, including Roger, who has sustained a legacy of brilliance and commitment to science and the deepening of our understanding of human life.”

Roger Kornberg received his undergraduate degree in chemistry from Harvard in 1967 and his doctorate in chemistry from Stanford in 1972, studying the motion of lipids in cell membranes. He was a postdoctoral fellow and member of the scientific staff at the Laboratory of Molecular Biology in Cambridge, U.K., from 1972 to 1975. He joined Harvard Medical School in 1976 as an assistant professor in biological chemistry. Kornberg returned to Stanford in 1978 as a professor in structural biology. He served as department chair from 1984 until 1992.

Kornberg is an elected member of the National Academy of Sciences and of the American Academy of Arts and Sciences, and an honorary member of the Japanese Biochemical Society. He is editor of the Annual Reviews of Biochemistry. He has written more than 180 peer-reviewed journal articles.

His previous honors and awards include the Eli Lilly Award (1981), the Passano Award (1982), the Harvey Prize (1997), the Gairdner International Award (shared in 2000 with Robert Roeder), the Welch Award (2001) and the Grand Prix of the French Academy of Sciences (2002).

“One of the benefits of the recognition of work such as ours is that it encourages continued support of fundamental issues like this one,” said Kornberg. “Many of the major advances in human health have their origins in the pursuit of basic biological knowledge.”

His funding sources agree. “Through decades of elegant, state-of-the art studies in biochemistry and structural biology, Roger Kornberg has revealed the mechanism underlying how cells transcribe genetic information," said Jeremy M. Berg, PhD, director of the National Institute of General Medical Sciences, which has funded Kornberg’s research since 1979. “This knowledge sheds light on a fundamental process that is key to health and disease. The achievement also demonstrates the power of innovative approaches to probe the many complicated molecular assemblies essential to life.”

Despite the kudos, wining such a prestigious award can create complications: Kornberg was scheduled schedule to fly to Pittsburgh this evening to receive the Dickson Prize in Medicine. When he called to cancel his flight, the Travelocity operator wanted to know the reason for the cancellation. There was a pause, and a gulp.

“Well,” he said. “I just won the Nobel Prize in Chemistry.” There’s no word yet as to the operator’s response, but perhaps he can roll the ticket over to his upcoming trip to Sweden.

“I'm looking forward to being in Stockholm, where we have many friends,” said Arthur Kornberg, remembering his own award 47 years ago. “They put on a great party.”
