Interference RNA technology is one of the most exciting new developments in genetics in recent years

In April 2004, Cancer Research UK and the Netherlands Cancer Institute announced creation of a 24,000-molecule iRNA library, designed to inactivate about 8,000 human genes. One hope for this library is its application in combating cancer. How might iRNA be implemented in cancer treatment?


Cancers for which the genetic basis is understood might be treated by preventing gene expression through iRNA-mediated gene silencing. Use of this technology may depend on the type of cancer and its localization.
