The apoptosome is a large quaternary protein structure formed in the process of apoptosis. (wikipedia.org)
The term Apoptosome was first introduced in Yoshihide Tsujimoto's 1998 paper "Role of Bcl-2 family proteins in apoptosis: apoptosomes or mitochondria? (wikipedia.org)
The apoptosome is a multimolecular holoenzyme complex assembled around the adaptor protein Apaf1 (apoptotic protease activating factor 1) upon mitochondria-mediated apoptosis which must be stimulated by some type of stress signal. (wikipedia.org)
The apoptosome triggers the activation of caspases in the intrinsic pathway of apoptosis. (wikipedia.org)
1996). This work shows that it has anti-apoptotic activity and can protect against Bak- and Apaf-1-induced apoptosis. (uni-frankfurt.de)
Flow cytometry analysis showed that VALD-3 triggered cell cycle arrest and induced apoptosis of breast cancer cells. (researchsquare.com)
This study is the first to show that VALD-3 induces apoptosis and cell cycle arrest in human breast cancer cells by suppressing Wnt/β-catenin signaling, indicating that it could be a potential drug for the treatment of breast cancer. (researchsquare.com)
In order to delineate the combined contributions of XIAP and the apoptosome molecular timer to apoptosis execution we utilised a systems modelling approach. (uni-stuttgart.de)
In contract using the cytoprotective part of molecular chaperones it's been shown, they can prevent stress-induced apoptosis [29, 30]. (nuche.org)
Overexpression of Hsp70 chaperones (ORP150 belongs to the family members) prevents cytochrome c launch from mitochondria, blocks apoptosome development by binding towards the apoptotic protease-activating element (Apaf-1), inhibits the discharge of apoptosis-inducing element (AIF) from mitochondria, and prevents the increased loss of mitochondrial transmembrane potential. (nuche.org)
TUNEL and western blot assay showed that KTC could induce apoptosis of endometriotic tissues, accompanied with the increased protein expression of caspases 8 and 9, activated caspase-3, and cytochrome c in a dose-dependent manner. (hindawi.com)
In the intrinsic pathway of apoptosis, cell-damaging signals promote the release of cytochrome c from mitochondria, triggering activation of the Apaf-1 and caspase-9 apoptosome. (duke.edu)
In an ex vivo model KNK437 was used as an inhibition model assay of HSP70, showed dose-dependent inhibition of cell growth and burst formation unit erythroid (BFU-E) in PV and ET, increased apoptosis in the erythroid lineage, and decreased pJAK2 signaling, as well as a specific siRNA for HSP70. (biomedcentral.com)
The subsequent release of Cytochrome C inside the citoplasm of the cells induces the formation of a multiprotein complex, called apoptosome, that activates the caspase cascade through caspase-9 (C9) leading to Apoptosis. (parathyroid-hormone1-34.com)
In a previous study we showed that pre-incubation with TNFα sensitizes primary murine hepatocytes to Fas ligand (FasL) induced apoptosis [2]. (biospraysehatalami.com)
Activates2
Promotes apoptosome formation and activates caspase-9/caspase-3 pathway. (rndsystems.com)
Cytochrome CYT997 (Lexibulin) c activates the apoptosome composed of Apaf-1 and caspase-9 which finally cleaves and activates the executioner caspase-3 to stimulate cell loss of life. (biospraysehatalami.com)
Cytochrome10
In mammalian cells, once cytochrome c is released, it binds to the cytosolic protein Apaf-1 to facilitate the formation of an apoptosome. (wikipedia.org)
An early biochemical study suggests a two-to-one ratio of cytochrome c to apaf-1 for apoptosome formation. (wikipedia.org)
The mammalian apoptosome had never been crystallized, but a human APAF-1/cytochrome-c apoptosome has been imaged at lower (2 nm) resolution by cryogenic transmission electron microscopy in 2002, revealing a heptameric wheel-like particle with 7-fold symmetry. (wikipedia.org)
Recently, a medium resolution (9.5 Ångström) structure of human apoptosome was also solved by cryo-electron microscopy, which allows unambiguous inference for positions of all the APAF-1 domains (CARD, NBARC and WD40) and cytochrome c. (wikipedia.org)
The stable APAF-1 and cytochrome multimeric complex fit this description, and is now called the apoptosome. (wikipedia.org)
The formation of the apoptosome requires the presence of ATP/dATP and cytochrome c in the cytosol. (wikipedia.org)
GSDME-N terminal domain also permeabilizes the mitochondrial membrane, releasing cytochrome C and activating the apoptosome. (adipogen.com)
The principal goals for Bcl-XL are Bak and Bax, which migrate to and oligomerize over the external mitochondrial membrane and therefore alter the permeability from the mitochondria, resulting in the discharge of small substances, which includes cytochrome sets off the set up of apoptosomes and, hence, activation of caspase cascade (13, 14, 17). (careersfromscience.org)
In response to apoptotic stimulus, permeabilized mitochondria release cytochrome c into the cytoplasm, where cytochrome c forms an apoptosome with Apaf-1 and caspase-9 and triggers the caspase cascade. (biomedcentral.com)
When released into the cytosol, cytochrome c binds to APAF-1, which oligomerizes to form a complex or apoptosome. (xpressbioeurope.com)
Caspase cascade1
This protein complex assembly called "apoptosome" leads to the activation of Casp-9 which then initiates or amplifies the caspase cascade. (uni-frankfurt.de)
XIAP4
Recent findings have shown that autocleavage of PC9 to Caspase 9 (C9) p35/p12 not only permits XIAP-mediated C9 inhibition but also temporally shuts down apoptosome activity, forming a molecular timer. (uni-stuttgart.de)
We demonstrate that cooperative recruitment of PC9 to the apoptosome, based on existing PC9-apoptosome interaction data, is important for efficient formation of PC9 homodimers, autocatalytic cleavage and dual regulation by XIAP and the molecular timer across biologically relevant PC9 and APAF1 concentrations. (uni-stuttgart.de)
It was shown that when cytoplasmic survivin is just not phosphorylated at S20 it binds XIAP and enhances XIAP stability by defending it from proteaso mal degradation as a result enabling antagonization of apoptosome mediated cell death via the capacity of XIAP to inhibit caspase three, 7 and 9 activation in vivo. (faksignaling.com)

Adaptor protein1
Upon cytosolic entry, it serves as a cofactor in the formation of the "apoptosome," a complex consisting of the adaptor protein Apaf-1 and procaspase-9, which in turn causes the activation of caspase-9 and downstream caspases, such as caspase-3 ( Chinnaiyan, 1999 ). (rupress.org)
