Apoptosis: regulation and relevance to toxicology

Hum Exp Toxicol. 1995 Mar;14(3):234-47. doi: 10.1177/096032719501400302.

Abstract

1. Apoptosis is a remarkably stereotyped morphological event across all tissues in response to a vast array of damaging agents. 2. Our very existence depends upon a willing exchange of old life for new: apoptotic cell death is our guardian and saviour from genetic damage. 3. There is a close link between cell proliferation and apoptosis: When a cell picks up the machinery to proliferate it also acquires an abort pathway--'better dead than wrong'. 4. A wide variety of highly conserved genes have been implicated in triggering apoptosis. 5. The release of DNA loops from the nuclear scaffold is a more crucial intracellular event than DNA 'laddering' in apoptotic cells. 6. The manipulation of apoptotic rates in many of the common diseases in man will be a major therapeutic strategy in the future.
