The Pioneering Discovery of MicroRNA
In 1992, Gary Ruvkun and Victor Ambros made a groundbreaking discovery that would redefine the landscape of gene regulation: microRNA. Initially, this revolutionary finding did not garner the recognition it deserved, as the evolutionary biology community was skeptical about the significance of these small RNAs. Ruvkun recalls that, at the time, their work seemed ordinary, lacking the buzz typically associated with groundbreaking scientific breakthroughs. However, the true potential of microRNA would gradually reveal itself, marking a transformative moment in genetic research.
Following their publication in the journal Cell in 1993, Ruvkun and Ambros faced a tepid response from the scientific community. Many experts were uncertain whether the microRNAs they identified in the C. elegans roundworm were relevant to other species, particularly humans. Despite receiving NIH grants that supported their research, it wasn’t until other scientists began to explore the implications of microRNA that interest surged, ultimately cementing the discovery’s importance in the realm of RNA research.
