Abstract:
:The recognition that apoptosis is regulated by an evolutionarily conserved set of polypeptides from the nematode Caenorhabditis elegans to humans suggests that a conserved set of biochemical mechanisms may also he involved in the response. Work from a number of independent laboratories suggests that alterations in cytosolic Ca2+ homeostasis represent one such candidate mechanism, and molecular targets for Ca2+ are now being identified. This review will summarize what is known about the role of Ca2+ in the regulation of apoptosis and discuss how Ca2+ might interact with some of the other biochemical signals implicated in cell death.
