In 1998, Andrew Fire, Craig Mello and their coworkers discovered that double-stranded RNA injected into a worm could cause the specific destruction of the normal mRNA from the gene with the same sequence - thus 'silencing' the gene's function. This process came to called "RNA interference," or "RNAi". This technique allowed researchers to powerfully block the function of a specific gene in the model organism C. elegans. Researchers soon discovered that RNAi could block gene function in other organisms, from plants to humans. In fact, the phenomenon had been discovered earlier in plants, but the generality of RNAi had not been recognized. Now it became obvious that RNAi would not only be a powerful technique for researchers to study the function of genes, but that RNAi would likely become an important tool in the treatment of disease. In this case, the medical application of RNAi has progressed quite rapidly: the first clinical trials of an RNAi-based therapy were begun in 2004 to treat age-related macular degeneration, a condition that causes blindness.
