Won 2004 Nobel Prize for chemistry

IRWIN ROSE, 1926 - 2015

On an October morning in 2004, a bleary-eyed UC Irvine chemistry professor checked to see who had won the Nobel Prize in chemistry. He found the names of a team of three scientists, including an American named Irwin Rose.

“Wait a second,” James Nowick recalled thinking. “That’s Ernie! That’s the guy I’m working with!”

Nowick called up his friend, who was relieved to find it wasn’t yet another reporter. The humble scientist simply wanted to get back to the lab, “and by the end of the day, he did,” Nowick recalled.

Rose died Tuesday in Deerfield, Mass., at the age of 88, according to UC Irvine spokeswoma­n Janet Wilson.

A sharp, passionate and curious enzymologi­st, Rose conducted his prize-winning work on how a cell gets rid of unwanted proteins. It became textbook material. But he continued to conduct experiment­s, publish scientific articles and pursue the intricacie­s of specific enzymes well into his Orange County retirement.

“By the time the Nobel Prize was awarded, he had moved on to other questions,” Nowick said. “He never dwelled on the past. He always moved on to new opportunit­ies and new frontiers.”

Rose was born in Brooklyn, N.Y., on July 16, 1926. He spent his teenage years in Spokane, Wash., hiding out in the library and reading scientific journals, according to an article in the local Spokesman-Review.

He received a doctorate in 1952 from the University of Chicago and taught biochemist­ry at Yale University until joining the Fox Chase Cancer Center in Philadelph­ia in the 1960s.

At the time, little had been understood about how cells work, said Dr. Jonathan Chernoff, the center’s scientific director.

Most scientists had focused on how protein was synthesize­d, but Rose harbored an interest in just the opposite: how protein was destroyed.

“Part of his genius was recognizin­g these sort of important, but off beat, questions that other people weren’t focused on,” Chernoff said.

For about two decades, Rose made little progress. But after meeting two other researcher­s, Rose invited them to Fox Chase for the summer, and they brought a new technique for breaking cells open and studying them in a test tube, Chernoff said.

Rose and his colleagues succeeded in detailing the mechanism for how enzymes are involved in attaching ubiquitin to old proteins, which marks them for destructio­n.

The discoverie­s led to at least one drug already on the market, Velcade, which is now used to a treat multiple myeloma.

“There are many, many more in the pipeline, no doubt,” one of his research partners, Aaron Ciechanove­r, said by phone at a news conference following the Nobel announceme­nt.

Cancer cells make a tremendous amount of protein. If they can’t regulate the protein disposal, then the cells die, Chernoff said. He compared the effect of too many unwanted proteins on such cancerous cells to how a clogged garbage disposal might hinder trying to wash the dishes.

Rose retired in 1997 to Laguna Woods and joined the physiology and biophysics department­s at UC Irvine, where he shared lab space with Ralph Bradshaw, then a professor in the department, whom he had met earlier in his career.

Rose had come by to see Bradshaw, saying that he was thinking of moving to Orange County and wondering if there might be a place he could work. Bradshaw told him of course.

But months passed with no word from his friend, until one day, “he walks into my office and says, ‘Here I am,’ ” Bradshaw recalled.

Bradshaw found a desk for him in the corner, such as a graduate student might have, where “he was as happy as he could be.”

“You get so much attention and notoriety,” Rose said about the award in a 2005 interview at UC Irvine. “It’s been different. I’ve been able to do some work, but not as much as I’d like to.”

Rose is survived by his wife, Zelda; sons Frederic, Robert and Howard; a brother and five grandchild­ren. He was preceded in death by his daughter Sarah.
