Born in 1953, Victor Ambros’s passion for biology led him to pursue a Ph.D. in genetics and developmental biology. His scientific career took a major turn during his time at Harvard University, where he worked with Gary Ruvkun on genetic mechanisms in Caenorhabditis elegans, a tiny roundworm often used in biological research. Their collaboration resulted in the discovery of lin-4, the first identified microRNA, in the early 1990s.

At the time, most scientists believed that genes primarily worked by coding for proteins, the molecular workhorses of the cell. However, Ambros and Ruvkun's work revealed that lin-4 didn’t code for any protein. Instead, it produced a small RNA molecule that regulated other genes by preventing the production of their corresponding proteins. This unexpected discovery of post-transcriptional gene regulation opened an entirely new area of RNA biology.

MicroRNAs, such as lin-4, act as critical regulators of gene expression. By binding to messenger RNA (mRNA), they can inhibit the production of proteins, which are the functional products of genes. Ambros and Ruvkun's work revealed that microRNAs play a key role in controlling a wide range of biological processes, including cell growth, differentiation, and apoptosis (programmed cell death). Their discovery changed how scientists understood gene regulation, offering insights into how cells control their behavior and respond to their environment.

The discovery of microRNAs has vast implications for both basic science and medicine. MicroRNAs are now understood to be crucial in many diseases, including cancer, where their abnormal regulation can lead to unchecked cell growth. As a result, researchers are exploring the use of microRNAs as biomarkers to diagnose diseases earlier or as targets for new therapies that can reprogram faulty gene regulation.

Their findings have also revealed that microRNAs are evolutionarily conserved across species, from plants to humans, underlining their importance in the biology of all living organisms.

Victor Ambros currently serves as a professor at the University of Massachusetts Chan Medical School, where his research continues to delve into the intricate mechanisms of gene regulation. His Nobel Prize recognition cements his legacy in the scientific community, and his work has sparked thousands of research studies in molecular biology, biotechnology, and medical research.

The Nobel Committee awarded Ambros and Ruvkun for what it called the discovery of "a new world of RNA biology." The recognition celebrates how their work revolutionized the understanding of gene regulation, with far-reaching effects on both health and disease. Their research continues to inspire the next generation of scientists, illustrating the profound impact of fundamental discoveries in biology.

Victor Ambros’s journey from investigating the genetic mechanisms of a roundworm to becoming a Nobel laureate is a testament to the unpredictable and transformative nature of science. His discovery of microRNA has revolutionized the understanding of gene regulation and has the potential to unlock new medical treatments. The 2024 Nobel Prize not only honors his past achievements but highlights the ongoing importance of this area of research in advancing human health.
