Apoptosis and cancer chemotherapy

Trends Cell Biol. 2001 Nov;11(11):S22-6. doi: 10.1016/s0962-8924(01)02124-9.

Abstract

The explosion of interest in apoptosis amongst cancer biologists has been underpinned by the hope that a mechanistic understanding of cell death will inform our understanding of tumour drug resistance. A framework for drug-induced apoptosis can now be described in which a balance exists between intrinsic and extrinsic survival signals and drug-induced death signals. Pro- and anti-apoptotic signals impact upon pro-apoptotic members of the Bcl-2 family of proteins, which ultimately control the cellular fate. This framework suggests multiple points at which therapeutic interventions could be made to overcome drug resistance and, in addition, generates novel molecular targets for the induction of apoptosis in cancer cells.
