**Stockholm, Sweden** – Victor Ambros and Gary Ruvkun have been awarded the 2024 Nobel Prize in Physiology or Medicine for their groundbreaking discovery of microRNAs. These tiny pieces of RNA, about 20 base pairs long, play a vital role in regulating gene activity in animals and plants.

Ambros and Ruvkun’s discovery, made while studying mutant strains of the nematode worm Caenorhabditis elegans, revealed a previously unknown mechanism of gene control. While DNA contains the instructions for making proteins, microRNAs act as “tiny switches” that control the production of these proteins by binding to messenger RNAs (mRNAs). This binding can lead to the breakdown of the mRNA before protein production can occur, effectively silencing the gene.

Their findings, initially made in the 1980s and 1990s, were initially met with limited attention. However, with the discovery of more microRNAs and their widespread presence across organisms, the significance of their work became evident.

The impact of Ambros and Ruvkun’s work extends beyond basic research. The understanding of microRNAs has opened up new avenues for medical therapies. Scientists are exploring the potential of microRNAs for treating conditions like cancer and developing new diagnostic tools.

“Their seminal discovery of microRNAs has introduced a new and unexpected mechanism of gene regulation,” said Olle Kämpe, vice-chair of the Nobel committee for physiology and medicine. “These are important for our understanding of embryological development, normal physiology and diseases such as cancer.”

The Nobel Prize in Physiology or Medicine recognizes the significant 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 groundbreaking advancements in medicine and biology.
