By Amplifying Cell Death Signals, Scientists Make Precancerous Cells Self-destruct

On the cellular level, death signals can actually be life saving -- by killing off abnormally dividing cells before they turn cancerous. Now, Rockefeller University researchers have found a way to amplify these signals by turning a life affirming protein into a killer. The findings not only mark a breakthrough in the field but also open the door to a new line of drugs for cancer therapeutics.
