Nobel medicine buzz heats up
STOCKHOLM -- U.S. scientists who discovered an enzyme that broke new ground in research on cancer and aging are among potential candidates for the Nobel Prize in medicine, the first of six prestigious awards to be announced by the Nobel committees.
Another possible winner of Monday's $1.54 million medicine prize is a British researcher who discovered genetic fingerprinting that has helped solve crimes and settle paternity disputes.
The secretive Nobel committee at Stockholm's Karolinska Institute will announce the winner after a final vote Monday morning, but won't even say who's on the short list before then.
"We have been working on this since February," said Hans Jornvall, secretary of the Nobel committee that reviews research nominated for the award.
Last year, the Nobel Prize in medicine went to Americans Andrew Z. Fire and Craig C. Mello for discovering RNA interference, a process that can silence specific genes.
American researchers Elizabeth Blackburn, Carol W. Greider and Jack W. Szostak have figured prominently in Nobel speculation in recent years for predicting and discovering an enzyme called telomerase.
Their work set the stage for research suggesting that cancer cells use telomerase to sustain their uncontrolled growth. Scientists are studying whether drugs that block the enzyme can fight the disease. In addition, scientists believe that the DNA erosion the enzyme repairs might play a role in age-related illnesses.
Sir Alec Jeffreys of the University of Leicester also is often mentioned by experts as a possible candidate. Jeffreys found in 1984 that a DNA sample could be linked to the person it came from — a finding that has come into play in court cases in which DNA evidence has exonerated convicted murderers.
It has also been used to help identify the victims of mass disasters, such as the Sept. 11, 2001, terror attacks in New York and Washington.
Karin Bojs, science editor at the Swedish newspaper Dagens Nyheter— who correctly guessed two of last year's Nobel Prizes — predicted that the medicine award would go to American David Julius and Israeli Baruch Minke for research on how the human body reacts to heat and pain.
