U.S. scientists Victor Ambros and Gary Ruvkun were awarded the 2024 Nobel Prize in Medicine on Monday for their groundbreaking discovery of microRNA and its pivotal role in the growth and survival of multicellular organisms.
Their research shed light on how cells specialize and differentiate into various types—such as muscle and nerve cells—despite all cells in an organism sharing the same set of genes and instructions for growth and life.
Describing the experience of being thrust into the global spotlight, Ruvkun said, "The Nobel is akin to what we call 'The Show' in Major League Baseball. It's not just any show; it's THE show."
He joked that collaborating with Ambros and receiving previous awards meant they had been "joined at the hip for quite a while".
"That's been great. He's a wonderful guy," Ruvkun added by phone. Ambros seconded by saying he was happy to share the award with "a great friend".
The Nobel Assembly, the award-giving body, said in a statement that the laureates discovered a new class of tiny RNA molecules, which play a crucial role in gene regulation.
"Their groundbreaking discovery revealed a completely new principle of gene regulation that turned out to be essential for multicellular organisms, including humans," the assembly said.
Also speaking to Reuters, Ambros described microRNA as a "communication network amongst genes that enables the cells in our bodies to generate all kinds of different complex structures and functions".
Ambros is a professor at the University of Massachusetts Medical School, while Ruvkun is a professor at Harvard Medical School and also affiliated with Massachusetts General Hospital in Boston.
In the late 1980s, Ambros and Ruvkun undertook postdoctorate studies in the laboratory of Robert Horvitz, himself a Nobel Prize winner in 2002, studying a 1 mm long roundworm.
Their discoveries on how certain microRNAs in the roundworm govern growth of organs and tissue was initially dismissed as specific to the species.
More work published by Ruvkun's research group in 2000, however, showed that all animal life had relied on the mechanism for more than 500 million years.
BUILDING BLOCKS FOR LIFE
MicroRNA comes into play when single-strand messenger RNA - the subject of last year's Nobel Prize in medicine - is decoded and translated into making proteins, the building blocks of all human and animal life.
Messenger RNA, or mRNA, in turn, emerges from the universal blueprint in every cell nucleus, the double-helix DNA.
Professor Gunilla Karlsson Hedestam of the Karolinska Institute said that, while the 2023 prize was linked to the specific use in COVID-19 vaccines, this year's award was for a leap in basic understanding with many potential future applications.
Janosch Heller, Assistant Professor in Biomedical Sciences at Dublin City University, who was not involved in selecting the winners, said that the findings had boosted the understanding of diseases such as epilepsy.
The winners of the prize for physiology or medicine are selected by the Nobel Assembly of Sweden's Karolinska Institute medical university and receive a prize sum of 11 million Swedish crowns ($1.1 million).
As in every year, the physiology or medicine prize was the first in the crop of Nobels, arguably the most prestigious prizes in science, literature and humanitarian endeavour, with the remaining five set to be unveiled over the coming days.
Created in the will of Swedish dynamite inventor and businessman Alfred Nobel, the prizes have been awarded for breakthroughs in science, literature and peace since 1901, while economics is a later addition.
Past winners of the Nobel medicine prize include many famous researchers such as Ivan Pavlov in 1904, most known for his experiments on behaviour using dogs, and Alexander Fleming, who shared the 1945 prize for the discovery of penicillin.
Last year's medicine prize was awarded to the runaway favourites Katalin Kariko, a Hungarian scientist, and US colleague Drew Weissman, for discoveries that paved the way for COVID-19 vaccines that helped curb the pandemic.
Steeped in tradition, the science, literature and economics prizes are presented to the laureates in a ceremony on Dec 10, the anniversary of Alfred Nobel's death, followed by a lavish banquet at Stockholm city hall. Separate festivities attend the winner of the peace prize in Oslo on the same day.
