**Stockholm, Sweden:** American scientists Victor Ambros and Gary Ruvkun have been awarded the 2023 Nobel Prize in Medicine for their groundbreaking discovery of microRNA and its crucial role in regulating gene expression. This discovery, made in the 1980s while studying the tiny roundworm C. elegans, has revolutionized our understanding of how cells control protein production.

MicroRNA are small molecules that bind to messenger RNA (mRNA), the blueprint for protein production, effectively silencing the production of specific proteins. This process is vital for the proper development and functioning of all multicellular organisms, including humans.

Ambros and Ruvkun, working independently, identified a key microRNA, lin-4, which was found to inhibit the expression of the lin-14 gene in C. elegans. This groundbreaking discovery challenged the prevailing belief that gene regulation only occurred at the mRNA level.

Their work has paved the way for understanding how microRNAs regulate a vast array of biological processes and how dysregulation of these molecules can contribute to diseases like cancer, diabetes, and autoimmunity.

“We know from genetic research that cells and tissues do not develop normally without microRNAs,” emphasizes the Nobel Prize website. “Abnormal regulation by microRNA can contribute to cancer, and mutations in genes coding for microRNAs have been found in humans, causing conditions such as congenital hearing loss, eye and skeletal disorders.”

This Nobel Prize recognizes the profound impact of Ambros and Ruvkun’s discovery, which has opened up new avenues for research into gene regulation and its implications for human health. The duo’s work has provided valuable insights into complex biological processes and holds immense potential for future therapeutic interventions.
