Deficiency in caspase-9 or caspase-3 induces compensatory caspase activation
Nature Medicine, 2000Dysregulation of apoptosis contributes to the pathogenesis of many human diseases. As effectors of the apoptotic machinery, caspases are considered potential therapeutic targets. Using an established in vivo model of Fas-mediated apoptosis, we demonstrate here that elimination of certain caspases was compensated in vivo by the activation of other ...

Caspases belong to a family of highly conserved aspartate-specific cysteine proteases and are members of the interleukin-1beta-converting enzyme family, present in multicellular organisms. The caspase gene family consists of 15 mammalian members that are grouped into two major sub-families, namely inflammatory caspases and apoptotic caspases.

Apoptosis, 2009
Developmental and tissue homeostasis is a delicate balance between cell proliferation and cell death. The activation of caspases, a conserved family of cysteine proteases, is a main event in the initiation and execution of programmed cell death. While caspases have been characterized from many organisms, comparatively little is known about insect ...

Caspases comprise a structurally related group of cysteine proteases that share a dominant primary specificity for cleaving peptide bonds following Asp residues. Present in the cytosol of all animals, the caspases participate in proteolytic pathways required for executing programmed cell death, or apoptosis.

The expedition into the apoptosis signaling pathway, although it has just begun, has resulted in the discovery of a significant number of remarkable signaling molecules at all levels of this novel pathway After the pinnacle of this frenetic cloning effort has been reached, however, it is important to put this pathway and its constituents into a ...

Death without caspases, caspases without death
Trends in Cell Biology, 2004Apoptosis is a conserved cell-death process displaying characteristic morphological and molecular changes including activation of caspase proteases. Recent work challenges the accepted roles of these proteases. New investigations in mice and the nematode Caenorhabditis elegans suggest that there could be caspase-independent pathways leading to cell ...

Essays in Biochemistry, 2002
The ability of metazoan cells to undergo programmed cell death is vital to both the precise development and long-term survival of the mature adult. Cell deaths that result from engagement of this programme end in apoptosis, the ordered dismantling of the cell that results in its 'silent' demise, in which packaged cell fragments are removed by ...

Caspase activation is the 'point of no return' commitment to cell death. Synthesized as inactive zymogens, it is essential that the caspases remain inactive until the death signal is received. It is known for the downstream executioner caspases-3 and -7 that the activation event is proteolytic cleavage, and this had been assumed to apply to the ...

The main effectors of apoptosis encompass proteases from the caspase family, which reside as latent precursors in most nucleated animal cells. The apoptotic caspases constitute a minimal two-step signaling pathway. The apical (initiator) caspases are activated within oligomeric signaling complexes in response to apoptotic stimuli.

Caspase cascades and caspase targets
2000Apoptosis is an evolutionarily conserved form of cell suicide. Cells that die by apoptosis are disassembled in a stereotypical manner resulting in a characteristic ‘apoptotic morphology’. It was this characteristic, uniform morphology displayed by cells during apoptosis which led to the assumption that cells contain a similar execution machinery ...
