Two Americans, German win Nobel medicine prize

The winners’ discoveries in the 1970s, ‘80s and ‘90s have helped doctors diagnose a severe form of epilepsy and immune deficiency diseases in children.

STOCKHOLM — Two Americans and a German-American won the Nobel Prize in medicine on Monday for discovering how key substances are transported within cells, a process involved in such important activities as brain cell communication and the release of insulin.

James Rothman, 62, of Yale University, Randy Schekman, 64, of the University of California, Berkeley, and Dr. Thomas Sudhof, 57, of Stanford University shared the $1.2 million prize for their research on how tiny bubbles called vesicles act as cargo carriers inside cells.

This traffic control system ensures that the cargo is delivered to the right place at the right time and keeps activities inside cells from descending into chaos, the committee said. Defects can be harmful, leading to neurological diseases, diabetes and disorders affecting the immune system.

“Imagine hundreds of thousands of people who are traveling around hundreds of miles of streets; how are they going to find the right way? Where will the bus stop and open its doors so that people can get out?” Nobel committee secretary Goran Hansson said. “There are similar problems in the cell.”

The winners’ discoveries in the 1970s, ‘80s and ‘90s have helped doctors diagnose a severe form of epilepsy and immune deficiency diseases in children, Hansson said. In the future, scientists hope the research could lead to medicines against more common types of epilepsy, diabetes and other metabolism deficiencies, he added.

Schekman said he was awakened at 1 a.m. at his home in California by the chairman of the prize committee, just as he was suffering from jetlag after returning from a trip to Germany the night before.

“I wasn’t thinking too straight. I didn’t have anything elegant to say,” he told The Associated Press. “All I could say was ‘Oh my God,’ and that was that.”

He called the prize a wonderful acknowledgment of the work he and his students had done and said he knew it would change his life.

“I called my lab manager and I told him to go buy a couple bottles of Champagne and expect to have a celebration with my lab,” he said.

In the 1970s, Schekman discovered a set of genes that were required for vesicle transport, while Rothman revealed in the 1980s and 1990s how vesicles delivered their cargo to the right places. Also in the ‘90s, Sudhof identified the machinery that controls when vesicles release chemical messengers from one brain cell that let it communicate with another.

“This is not an overnight thing. Most of it has been accomplished and developed over many years, if not decades,” Rothman told the AP.

Rothman said he lost grant money for the work recognized by the Nobel committee, but he will now reapply, hoping the Nobel prize will make a difference in receiving funding.

Sudhof, who was born in Germany but moved to the U.S. in 1983 and also has U.S. citizenship, told the AP he received the call from the committee while driving toward the city of Baeza, in southern Spain, where he was due to give a talk.

“I got the call while I was driving and like a good citizen I pulled over and picked up the phone,” he said. “To be honest, I thought at first it was a joke. I have a lot of friends who might play these kinds of tricks.”

The medicine prize kicked off this year’s Nobel announcements. The awards in physics, chemistry, literature, peace and economics will be announced by other prize juries this week and next. Each prize is worth 8 million Swedish kronor ($1.2 million).

Rothman and Schekman won the Albert Lasker Basic Medical Research Award for their research in 2002 — an award often seen as a precursor of a Nobel Prize. Sudhof won the Lasker award this year.
