Two scientists from the United States, Victor Ambros and Gary Ruvkun, have won the Nobel Prize in Medicine on Monday for their discovery of microRNA and its role in how genes are regulated, solving decades-old mystery, the Nobel Assembly at Sweden’s Karolinska Institute has said.
If gene regulation goes awry, it can lead to serious diseases such as cancer, diabetes or auto-immune illnesses.
“Their groundbreaking discovery revealed a completely new principle of gene regulation that turned out to be essential for multicellular organisms, including humans,” the jury said.
Ruvkun said he was shocked to win the prestigious prize
“It’s quite a sea change. I’ve won other awards in the past, but those were very quiet in comparison,” the 72-year-old professor at Harvard Medical School told AFP after receiving the news in a call from the prize committee in the early hours of Monday.
“There’s already been TV crews and photographers, and 300 email messages from friends!” he said, as his dog barked at the front door with more reporters arriving.
Ruvkun shared that he and Ambros are “buddies” and had a congratulatory video call that morning.
“We just FaceTimed to high-five. We’ve been friends for years.”
Ruvkun told Swedish public radio SR that he looked forward to the Nobel gala banquet on December 10 in Stockholm, where the laureates will receive their prizes from the hands of Sweden’s King Carl XVI Gustaf.
“It’s a party. You don’t think of a bunch of scientists as party animals but we really are,” he said.
Ruvkun told AFP the pair would be “celebrating like crazy,” praising Ambros as “always positive and wonderful.”
The Nobel committee failed to reach Ambros by telephone to give him the news. He heard it instead from an SR reporter who called.
“Wow, that’s incredible! I didn’t know that,” the 70-year-old professor at the University of Massachusetts Medical School said, adding, “Good. Wonderful.”
Collaborating but working separately, Ruvkun and Ambros researched a one-millimetre roundworm, C. elegans, to determine why cell mutations occurred and when.
“The seminal discovery of microRNA has introduced a new and unexpected mechanism of gene regulation,” Thomas Perlmann, secretary general of the Nobel Assembly, told reporters.
“MicroRNAs are important for our understanding of embryological development, normal cell physiology and diseases such as cancer,” he said.
– Medical trials underway –
A Biology professor at the Karolinska Institute, Gunilla Hedestam, told reporters that “though there are no very clear applications available yet in microRNAs, understanding them, knowing that they exist, understanding their counter regulatory networks, is always the first step.”
“There are quite a lot of trials ongoing, not only against cancer but also other diseases, cardiovascular, kidney diseases,” she said.
The Nobel Prize consists of a diploma, a gold medal and a $1 million cheque to be shared by the pair.
Last year, the medicine prize went to Katalin Kariko and Drew Weissman for work on messenger RNA (mRNA) technology that paved the way for COVID-19 vaccines.
The Nobel season continues this week with the announcement of the winners of the physics prize on Tuesday and the chemistry prize on Wednesday.
They will be followed by the much-anticipated prizes for literature on Thursday and peace on Friday.
The economics prize winds things up on Monday, October 14.
For Tuesday’s physics prize, Swedish public radio SR’s science experts suggested the honour could go to Swiss physicist Christoph Gerber, a pioneer in the development of the atomic force microscope.
“This is a microscope that gives 3D images on such an incredibly small scale that they sometimes are even atomic resolution,” said SR science reporter Camilla Widebeck.
The tool has become indispensable in nanotechnology and nano research, she added.
The Clarivate analytics group also highlighted David Deutsch and Peter Shor for their work on quantum algorithms and quantum computing.
