S.A. patient study promising

Abstract:
In a small study involving San Antonio patients, a team of researchers proved it's possible to trick cancer genes into switching themselves off.

The trick involves using tiny strands of material known as small-interfering RNA, or siRNA, which tells genes to stop making proteins. These siRNAs appear naturally in the body to tell healthy cells to stop growing.

The idea is called RNA interference, and for its discovery, scientists Andrew Fire and Craig Mello were awarded the 2006 Nobel Prize in Physiology or Medicine.

In the latest technology, developed by researchers at the California Institute of Technology, the strands were placed in protective nanoparticles covered with transferrin, a material that is absorbed into cells.
