Preferred Label : Apoptosis DNA Damage Pathway;
NCIt related terms : Apoptotic Signaling in Response to DNA Damage;
Alternative definition : BIOCARTA: The cellular activation of the caspase cascade resulting in cell death is
triggered by chemical damage to DNA which stimulates a sequence resulting in the cleavage
of BID or directly initiates the permeability transition of the mitochondrial membrane.
The permeability transition releases several factors including cytochrome c, AIF and
other factors in to the cytoplasm. Cytochrome c, a key protein in electron transport,
is released from mitochondria in response to apoptotic signals, and activates Apaf-1,
a protease released from mitochondria. Activated Apaf-1 activates caspase-9 and the
rest of the caspase cascade. The caspases are a class of cysteine proteases that includes
several representatives involved in apoptosis. The caspases convey the apoptotic signal
in a proteolytic cascade, with caspases cleaving and activating other caspases that
then degrade other cellular targets that lead to cell death. (This definition may
