**Stockholm, Sweden** – The 2023 Nobel Prize in Medicine has been awarded to **Victor Ambros** and **Gary Ruvkun** for their groundbreaking discovery of microRNAs, a new class of RNA molecules that play a crucial role in regulating gene activity.
Ambros and Ruvkun, both US researchers, made their discovery while studying the tiny roundworm *Caenorhabditis elegans* in the 1980s. Their research revealed that these microRNAs, which are short RNA molecules, act as “molecular switches” controlling which genes are turned on or off in different cell types.
This discovery revolutionized our understanding of gene regulation, a process that governs the development and function of all multicellular organisms, including humans. Prior to their work, scientists believed that gene regulation was primarily controlled by proteins called transcription factors. However, Ambros and Ruvkun demonstrated that microRNAs are essential players in this process, adding a new dimension to the existing knowledge.
“This fundamental discovery has transformed our understanding of gene regulation and its importance for normal development and disease,” stated the Nobel Assembly. “It has opened up vast new fields of research, and microRNAs are now being investigated as targets for the development of new therapies for a wide range of diseases.”
MicroRNAs are now known to play a critical role in a variety of biological processes, including development, immunity, and metabolism. Dysregulation of microRNA function has been linked to various diseases, including cancer, diabetes, and autoimmune disorders.
This year’s Nobel Prize in Medicine acknowledges the profound impact of Ambros and Ruvkun’s discovery on our understanding of gene regulation and its implications for human health. Their work has paved the way for future research and therapeutic advancements in a range of fields.
