Professor of Molecular Medicine, UMass Chan Medical School
UMass Chan Medical School researcher Victor R. Ambros, PhD, will share the 2024 Nobel Prize in Physiology or Medicine for his co-discovery of microRNA, the very short, single-stranded RNA molecules that are now understood to play a critical role in post-transcriptional gene regulation. A central figure in ribonucleic acid (RNA) biology, Dr. Ambros, the Silverman Chair in Natural Sciences and professor of molecular medicine at UMass Chan, will share the award with his longtime collaborator Gary B. Ruvkun, PhD, of Massachusetts General Hospital and Harvard Medical School.
Victor Ambros did his graduate research (1976-1979) with David Baltimore at MIT, studying poliovirus genome structure and replication. He began to study the genetic pathways controlling developmental timing in the nematode C. elegans as a postdoc in H. Robert Horvitz’s lab at MIT, and continued those studies while on the faculty of Harvard (1984-1992), Dartmouth (1992-2007), and the UMass Chan Medical School (2008-present). In 1993, members of the Ambros lab identified the first microRNA, the product of lin-4, a heterochronic gene of C. elegans. Since then, the role of microRNAs in development has been a major focus of his research.
