The fifth video released of the “RNA Explained Series”, is on RNA interference, or in short RNAi, and its applications to cure diseases. For its discovery, the 2006 Nobel Prize in Physiology or Medicine was awarded.
Imagine a tool that could eliminate specific disease-causing messages within a cell with pinpoint precision. For decades, scientists believed the flow of genetic information was a simple one-way street: DNA makes RNA, and RNA produces proteins.
In the late 1990s, that understanding was turned upside down with the discovery of RNA interference (RNAi). This natural defense mechanism allows cells to "silence" specific genes by destroying their messenger RNAs (mRNAs) before they can be translated into proteins.
Today, scientists are harnessing this power to develop RNAi-based therapies. By designing synthetic siRNAs, we can now target and destroy the instructions for harmful proteins, offering potential cures for genetic diseases, viral infections, and cancer.
