By amplifying cell death signals, scientists make precancerous cells self-destruct

When a cell begins to multiply in a dangerously abnormal way, a series of death signals trigger it to self-destruct before it turns cancerous. Now, in research to appear in the August 15 issue of Genes & Development, Rockefeller University scientists have figured out a way in mice to amplify the signals that tell these precancerous cells to die. The trick: Inactivating a protein that normally helps cells to avoid self-destruction.
