title: Molecular biology. Cancer fighter's modus operandi revealed.
abstract: Researchers have deciphered how a promising cancer drug acts like a smart bomb, homing in on only a very narrow range of its potential targets in the cell. The compound, known as STI-571, has shown remarkable success in early clinical trials on patients with chronic myelogenous leukemia. Now, in work reported on page 1938, scientists reveal just how the compound works--information that could aid in the design of similar cancer therapies.
