The 2024 Nobel Prize in Physiology or Medicine has been awarded to American biologists Victor Ambros and Gary Ruvkun. Their groundbreaking discovery of microRNA and its role in post-transcriptional gene regulation has revolutionized the field of molecular biology. The Nobel Assembly at the Karolinska Institute in Stockholm announced the award, recognizing their pioneering work in uncovering a fundamental principle of gene regulation.
The Discovery of microRNA
MicroRNA is a tiny molecule that controls gene activity within cells, specifically after transcription. This post-transcriptional gene regulation is crucial for allowing cells to perform diverse functions, despite all cells in the human body having the same genetic code. The discovery of microRNA revealed a new layer of gene regulation, explaining how cells can “switch on” the necessary genes to specialize into various types, such as muscle or nerve cells.
Importance and Impact of the Discovery of MicroRNA
The Nobel Assembly described Ambros and Ruvkun’s discovery as “fundamentally important for how organisms develop and function.” Their work has shown that the human genome encodes over one thousand microRNAs, emphasizing their significant role in the development and functioning of multicellular organisms, including humans. This discovery has opened new pathways for understanding genetic diseases and developing therapies targeting gene regulation mechanisms.

The Prize and Ceremony
The winners will receive a prize sum of 11 million Swedish kronor (approximately $1.1 million or ₹8.3 crore), in accordance with the traditions of Alfred Nobel’s bequest. The Nobel Prizes are awarded annually on December 10, the anniversary of Nobel’s death, in a ceremony held in Stockholm.
Context: Previous Nobel Prizes
Last year, the Nobel Prize in Medicine was awarded to Katalin Karikó and Drew Weissman for their groundbreaking work that enabled the development of mRNA vaccines against COVID-19. Their contributions played a crucial role in combating the global pandemic, showcasing the Nobel Prize’s tradition of recognizing impactful medical research.
