Victor Ambros and Gary Ruvkun were on Monday awarded the 2024 Nobel Prize in Physiology or Medicine for their discovery of microRNAs, a class of small molecules essential for gene regulation.
This year’s Nobel Prize focuses on the discovery of a vital regulatory mechanism used in cells to control gene activity. Genetic information flows from DNA to messenger RNA (mRNA), via a process called transcription, and then on to the cellular machinery for protein production. There, mRNAs are translated so that proteins are made according to the genetic instructions stored in DNA. Since the mid-20th century, several of the most fundamental scientific discoveries have explained how these processes work.
Our organs and tissues consist of many different cell types, all with identical genetic information stored in their DNA. However, these different cells express unique sets of proteins. How is this possible? The answer lies in the precise regulation of gene activity so that only the correct set of genes is active in each specific cell type. This enables, for example, muscle cells, intestinal cells, and different types of nerve cells to perform their specialized functions. In addition, gene activity must be continually fine-tuned to adapt cellular functions to changing conditions in our bodies and environment. If gene regulation goes awry, it can lead to serious diseases such as cancer, diabetes, or autoimmunity. Therefore, understanding the regulation of gene activity has been an important goal for many decades.
In the 1960s, it was shown that specialized proteins, known as transcription factors, can bind to specific regions in DNA and control the flow of genetic information by determining which mRNAs are produced. Since then, thousands of transcription factors have been identified, and for a long time it was believed that the main principles of gene regulation had been solved. However, in 1993, this year’s Nobel laureates published unexpected findings describing a new level of gene regulation, which turned out to be highly significant and conserved throughout evolution.
