Abstract
The importance of caspase activation during apoptosis has become eminently apparent in the last few years. The caspases participate in a proteolytic cascade activated in response to various stimuli, including anticancer drugs, that results in the systematic and orderly eradication of the cell. The core machinery of caspase activation is now emerging and involves multiple molecular complexes. We describe the two best-studied models of caspase activation, the mitochondrial pathway and the cell death receptor pathway, and discuss their involvement in caspase activation induced by various anticancer drugs used in chemotherapy. Defective apoptosis contributes to tumor growth and drug resistance. Understanding the activation and role of caspases in apoptosis may help develop new therapeutic strategies to circumvent drug resistance. Copyright 1999 Harcourt Publishers Ltd.
