Proteolytic cleavage of ras GTPase-activating protein during apoptosis. (1/647)p120-ras GTPase-activating protein (rasGAP) associates with Ras and negatively regulates Ras signaling by stimulating the intrinsic rate of Ras GTPase activity. rasGAP also associates with other cellular signaling proteins which suggest that rasGAP may play a role in coordinating other signal transduction pathways. Disruption of rasGAP in vivo results in extensive apoptosis. Fas-mediated apoptosis results in the activation of caspases that cleave cellular substrates which are important for maintaining cytoplasmic and nuclear integrity. We show here that rasGAP is proteolytically cleaved by caspases early in Fas-induced apoptosis of Jurkat cells. rasGAP was also cleaved by DNA-damaging chemotherapeutic agents and TNF-related apoptosis inducing ligand (TRAIL), also known as Apo2L. Based on the size of the products generated by cleavage of deletion mutants of rasGAP we predict that cleavage of rasGAP occurs in the hydrophobic region and between the SH2(2) and ras-p21 interacting domain which would leave an intact ras-p21 interacting domain. Interestingly, cleavage of rasGAP in vitro enhanced rasGAP hydrolysis activity. Our results demonstrate that diverse apoptotic stimuli cause caspase-mediated cleavage of rasGAP early in apoptosis.

Caspase activation by BCR cross-linking in immature B cells: differential effects on growth arrest and apoptosis. (2/647)The B cell lymphoma WEHI-231 has been used as a model to study immature B cell tolerance, based on its capacity to undergo growth arrest and programmed cell death on B cell receptor (BCR) cross-linking. Using this model to identify the molecular mechanisms underlying these processes, we found that BCR cross-linking results in the selective activation of caspase 7/Mch3, but not of the other two members of the CPP32 family, caspase 2/Nedd2 and caspase 3/CPP32. This was evidenced by the induction of proteolytic activity against the substrate for the CPP32 subfamily of caspases (z-DVED-AMC) in vitro, as well as PARP proteolysis in vivo and by the processing of the 35 kDa Mch3 into a 32 kDa species, which was later further proteolyzed. The general caspase inhibitor z-VAD-fmk, but not the CPP32 family inhibitor Ac-DEVD-CHO, blocked anti- micro-induced apoptosis, indicating that a caspase not belonging to the CPP32-like family is also implicated in anti- micro-triggered apoptosis. In contrast, z-VAD-fmk was not able to counteract growth arrest induced by anti- micro treatment, suggesting that caspase activation is not necessary for induction of growth arrest. Neither of the inhibitors prevented Mch3 processing; however, z-VAD-fmk prevented proteolysis of the p32 subunit, suggesting that further processing of this subunit is associated with apoptosis. Bcl-2 overexpression prevented anti- micro induction of CPP32-like activity and apoptosis, and blocked further processing of the Mch3 p32 subunit. In contrast, CD40 stimulation completely blocked the appearance of the p32 subunit in addition to blocking CPP32-like activity and apoptosis induced by BCR cross-linking. Moreover, only CD40 stimulation was able to prevent anti- micro-induced growth arrest, which was correlated with inhibition of retinoblastoma and of cyclin A down-regulation. In splenic B cells, Mch3 is also specifically proteolyzed ex vivo after induction of apoptosis by BCR cross-linking, demonstrating the specific involvement of caspase-7/Mch3 in apoptosis induced in B cell tolerance.

Activation of the apoptotic endonuclease DFF40 (caspase-activated DNase or nuclease). Oligomerization and direct interaction with histone H1. (3/647)DNA fragmentation factor (DFF) is a heterodimeric protein composed of 45-kDa (DFF45) and 40-kDa (DFF40) subunits, a protein that mediates regulated DNA fragmentation and chromatin condensation in response to apoptotic signals. DFF45 is a specific molecular chaperone and an inhibitor for the nuclease activity of DFF40. Previous studies have shown that upon cleavage of DFF45 by caspase-3, the nuclease activity of DFF40 is relieved of inhibition. Here we further investigate the mechanism of DFF40 activation. We demonstrate that DFF45 can also be cleaved and inactivated by caspase-7 but not by caspase-6 and caspase-8. The cleaved DFF45 fragments dissociate from DFF40, allowing DFF40 to oligomerize to form a large functional complex that cleaves DNA by introducing double strand breaks. Histone H1 directly interacts with DFF, confers DNA binding ability to DFF, and stimulates the nuclease activity of DFF40 by increasing its Kcat and decreasing its Km. (+info)
Synthesis of procaspases-3 and -7 during apoptosis in prostate cancer cells. (4/647)Cells differ in the time required to execute cell death after receipt of a death signal. One reason may be the requirement for de novo synthesis of components of the death pathway. TSU-Pr1 prostate cancer cells treated with okadaic acid demonstrated activation of caspase-3, PARP cleavage, and nuclear fragmentation by 24 h and apoptosis by 72 h. Levels of procaspase-3 and procaspase-7, the precursor molecules of two effector caspases, were not depleted during apoptosis. Levels of procaspase-3 and -7 mRNA increased steadily in TSU-Pr1 cells up to 72 h after exposure to okadaic acid. Nuclear run-off experiments showed that the increase in mRNA was not due to transcriptional activation of caspase-3 and -7 mRNA. Antisense caspase-3 and caspase-7 oligodeoxynucleotides caused a depletion of procaspases-3 and -7 and a delay in apoptosis of TSU-Pr1 cells. Caspase antisense oligodeoxynucleotides inhibited apoptosis to a similar extent as peptide inhibitors of cysteine proteases. Synthesis of procaspases-3 and -7 was necessary to sustain programmed cell death in TSU-Pr1 prostate cancer cells. (+info)
Caspases-3 and -7 are activated in goniothalamin-induced apoptosis in human Jurkat T-cells. (5/647)Goniothalamin, a plant styrylpyrone derivative isolated from Goniothalamus andersonii, induced apoptosis in Jurkat T-cells as assessed by the externalisation of phosphatidylserine. Immunoblotting showed processing of caspases-3 and -7 with the appearance of their catalytically active large subunits of 17 and 19 kDa, respectively. Activation of these caspases was further evidenced by detection of poly(ADP-ribose) polymerase cleavage (PARP). Pre-treatment with the caspase inhibitor benzyloxycarbonyl-Val-Ala-Asp fluoromethyl ketone (Z-VAD.FMK) blocked apoptosis and the resultant cleavage of these caspases and PARP. Our results demonstrate that activation of at least two effector caspases is a key feature of goniothalamin-induced apoptosis in Jurkat T-cells. (+info)
Implication of calpain in caspase activation during B cell clonal deletion. (6/647)In the absence of costimulating signals, B cell receptor (BCR) crosslinking on immature B cells triggers the apoptotic cell death program. In the WEHI-231 B cell lymphoma model, anti-IgM crosslinking triggers activation of caspase-7 independently of caspase-8, followed by apoptosis. Two main mechanisms for caspase-7 activation have been proposed: (i) caspase-8 recruitment to death receptors (Fas or tumour necrosis factor); and (ii) changes in mitochondrial membrane permeability and cytochrome c release, which activate caspase-9. Here we report that caspase-7 activation induced by BCR crosslinking is independent of caspase-8 and cytochrome c translocation from mitochondria to the cytosol, as well as of mitochondrial depolarization. In addition, in a cell-free system, the S-100 fraction of anti-IgM-treated WEHI-231 cells induces a caspase activation pattern different from that activated by cytochrome c and dATP. We demonstrate that calpain specifically triggers activation and processing of caspase-7 both in vitro and in vivo, and that both processes are inhibited by calpain inhibitors. Furthermore, calpain activation is associated with decreased expression levels of calpastatin, which is upregulated by CD40 ligation. These data confirm a role for calpain during BCR crosslinking, which may be critical for cell deletion by apoptosis during B cell development and activation. (+info)
Cleavage of automodified poly(ADP-ribose) polymerase during apoptosis. Evidence for involvement of caspase-7. (7/647)The abundant nuclear enzyme poly(ADP-ribose) polymerase (PARP) synthesizes poly(ADP-ribose) in response to DNA strand breaks. During almost all forms of apoptosis, PARP is cleaved by caspases, suggesting the crucial role of its inactivation. A few studies have also reported a stimulation of PARP during apoptosis. However, the role of PARP stimulation and cleavage during this cell death process remains poorly understood. Here, we measured the stimulation of endogenous poly(ADP-ribose) synthesis during VP-16-induced apoptosis in HL60 cells and found that PARP was cleaved by caspases at the time of its poly(ADP-ribosyl)ation. In vitro experiments showed that PARP cleavage by caspase-7, but not by caspase-3, was stimulated by its automodification by long and branched poly(ADP-ribose). Consistently, caspase-7 exhibited an affinity for poly(ADP-ribose), whereas caspase-3 did not. In addition, caspase-7 was activated and accumulated in the nucleus of HL60 cells in response to the VP-16 treatment. Furthermore, caspase-7 activation was concommitant with PARP cleavage in the caspase-3-deficient cell line MCF-7 in response to staurosporine treatment. These results strongly suggest that, in vivo, it is caspase-7 that is responsible for PARP cleavage and that poly(ADP-ribosyl)ation of PARP accelerates its proteolysis. Cleavage of the active form of caspase substrates could be a general feature of the apoptotic process, ensuring the rapid inactivation of stress signaling proteins. (+info)
Caspase-3 is the primary activator of apoptotic DNA fragmentation via DNA fragmentation factor-45/inhibitor of caspase-activated DNase inactivation. (8/647)Caspase-3 initiates apoptotic DNA fragmentation by proteolytically inactivating DFF45 (DNA fragmentation factor-45)/ICAD (inhibitor of caspase-activated DNase), which releases active DFF40/CAD (caspase-activated DNase), the inhibitor's associated endonuclease. Here, we examined whether other apoptotic proteinases initiated DNA fragmentation via DFF45/ICAD inactivation. In a cell-free assay, caspases-3, -6, -7, -8, and granzyme B initiated benzoyloxycarbonyl-Asp-Glu-Val-Asp (DEVD) cleaving caspase activity, DFF45/ICAD inactivation, and DNA fragmentation, but calpain and cathepsin D failed to initiate these events. Strikingly, only the DEVD cleaving caspases, caspase-3 and caspase-7, inactivated DFF45/ICAD and promoted DNA fragmentation in an in vitro DFF40/CAD assay, suggesting that granzyme B, caspase-6, and caspase-8 promote DFF45/ICAD inactivation and DNA fragmentation indirectly by activating caspase-3 and/or caspase-7. In vitro, however, caspase-3 inactivated DFF45/ICAD and promoted DNA fragmentation more effectively than caspase-7 and endogenous levels of caspase-7 failed to inactivate DFF45/ICAD in caspase-3 null MCF7 cells and extracts. Together, these data suggest that caspase-3 is the primary inactivator of DFF45/ICAD and therefore the primary activator of apoptotic DNA fragmentation. (+info)

Caspases are a conserved family of cysteine proteases. They play diverse roles in inflammatory responses and apoptotic pathways. Among the caspases is a subgroup whose primary function is to initiate apoptosis. Within their long prodomains, caspases-2, -9 and -12 contain a caspase activation and recruitment domain while caspases-8 and -10 bear death effector domains. Activation follows the recruitment of the procaspase molecule via the prodomain to a high molecular mass complex. Despite sharing some common features, other aspects of the biochemistry, substrate specificity, regulation and signaling mechanisms differ between initiator apoptotic caspases. Defects in expression or activity of these caspases are related to certain pathological conditions including neurodegenerative disorders, autoimmune diseases and cancer ...

Post-transcriptional control of executioner caspases by RNA-binding proteins - Surrey Research Insight Open Access
Caspases are key components of apoptotic pathways. Regulation of caspases occurs at several levels, including transcription, proteolytic processing, inhibition of enzymatic function, and protein degradation. In contrast, little is known about the extent of post-transcriptional control of caspases. Here, we describe four conserved RNA-binding proteins (RBPs)-PUF-8, MEX-3, GLD-1, and CGH-1-that sequentially repress the CED-3 caspase in distinct regions of the Caenorhabditis elegans germline. We demonstrate that GLD-1 represses ced-3 mRNA translation via two binding sites in its 3′ untranslated region (UTR), thereby ensuring a dual control of unwanted cell death: at the level of p53/CEP-1 and at the executioner caspase level. Moreover, we identified seven RBPs that regulate human caspase-3 expression and/or activation, including human PUF-8, GLD-1, and CGH-1 homologs PUM1, QKI, and DDX6. Given the presence of unusually long executioner caspase 3′ UTRs in many metazoans, translational control of ...

Last month, federal Judge Beth Phillips said in a ruling in a death penalty case that it weighed heavily on her that condemned inmate Herbert Smulls had no legal means to learn more about how Missouris execution drug is made.. Under a Missouri law enacted in 2007, information that could be used to identify Missouri executioners is exempt from the states open records law. Under one of the laws provisions, executioners can sue anyone who knowingly releases their identities. When Missouri hired a compounding pharmacy last fall to produce drugs for its lethal injections, the Department of Corrections said it considered the pharmacy, as part of the execution team, to be secret under the law.. By the time Smulls case got to Phillips, the 8th Circuit U.S. Court of Appeals had already ruled that he was not entitled to learn more about the pharmacists making Missouris drugs for executions. The issue was moot, the court said, because Smulls had not proposed a more humane way to die. Phillips denied ...

Caspase-6 is an enzyme that in humans is encoded by the CASP6 gene. CASP6 orthologs have been identified in numerous mammals for which complete genome data are available. Unique orthologs are also present in birds, lizards, lissamphibians, and teleosts. Caspase-6 has known functions in apoptosis, early immune response and neurodegenration in Huntingtons and Alzheimers disease. This gene encodes a protein that is a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes that undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme. This protein is processed by caspases 7, 8 and 10, and is thought to function as a downstream enzyme in the caspase activation cascade. Caspase 6 can also undergo self-processing without other members of the caspase family. Alternative ...
Caspase 12 is a protein that belongs to a family of enzymes called caspases which cleave their substrates at C-terminal aspartic acid residues. It is closely related to caspase 1 and other members of the caspase family, known as inflammatory caspases, which process and activate inflammatory cytokines such as interleukin 1 and interleukin 18. It is found on chromosome 11 in humans in a locus with other inflammatory caspases. CASP12 orthologs have been identified in numerous mammals for which complete genome data are available. The CASP12 gene is subject to polymorphism, which can generate a full length caspase protein (Csp12L) or an inactive truncated form (Csp12S). The functional form appears to be confined to people of African descent and is linked with susceptibility to sepsis; people carrying the functional gene have decreased responses to bacterial molecules such as lipopolysaccharide (LPS). A study in May 2009 by McGill University Health Centre has suggested that estrogen may serve to block ...

Silibinin, a natural flavonolignan, induces apoptosis in human bladder transitional-cell papilloma RT4 cells both in vitro and in vivo; however, mechanisms of such efficacy are not completely identified. Here, we studied the mechanisms involved in silibinin-induced apoptosis of RT4 cells having intact p53. Silibinin increased p53 protein level together with its increased phosphorylation at serine 15, activated caspase cascade and caused Bid cleavage for apoptosis. Silibinin-caused p53 activation was mediated via ATM-Chk2 pathway, which in turn induced caspase 2-mediated apoptosis. Pifithrin-α, a p53 inhibitor, reversed silibinin-induced caspase activation including caspase 2; however, caspase 2 inhibitor also reversed p53 phosphorylation suggesting a bidirectional regulation between them. Further, silibinin caused a rapid translocation of p53 and Bid into mitochondria leading to increased permeabilization of mitochondrial membrane and cytochrome c release into the cytosol. JNK1/2 activation was ...
Caspase-mediated cleavage of HuR in the cytoplasm contributes to pp32/PHAP-I regulation of apoptosis<...
TY - JOUR. T1 - Caspase-mediated cleavage of HuR in the cytoplasm contributes to pp32/PHAP-I regulation of apoptosis. AU - Mazroui, Rachid. AU - Di Marco, Sergio. AU - Clair, Eveline. AU - Von Roretz, Christopher. AU - Tenenbaum, Scott A.. AU - Keene, Jack D.. AU - Saleh, Maya. AU - Gallouzi, Imed Eddine. PY - 2008/1/14. Y1 - 2008/1/14. N2 - The RNA-binding protein HuR affects cell fate by regulating the stability and/or the translation of messenger RNAs that encode cell stress response proteins. In this study, we delineate a novel regulatory mechanism by which HuR contributes to stress-induced cell death. Upon lethal stress, HuR translocates into the cytoplasm by a mechanism involving its association with the apoptosome activator pp32/PHAP-I. Depleting the expression of pp32/PHAP-I by RNA interference reduces both HuR cytoplasmic accumulation and the efficiency of caspase activation. In the cytoplasm, HuR undergoes caspase-mediated cleavage at aspartate 226. This cleavage activity is ...

Welcome to CDC stacks | Turning ON Caspases with Genetics and Small Molecules - 30186 | CDC Public Access
Caspases, aspartate-specific cysteine proteases, have fate-determining roles in many cellular processes including apoptosis, differentiation, neuronal remodeling, and inflammation (for review, see Yuan & Kroemer, 2010). There are a dozen caspases in humans alone, yet their individual contributions toward these phenotypes are not well understood. Thus, there has been considerable interest in activating individual caspases or using their activity to drive these processes in cells and animals. We envision that such experimental control of caspase activity can not only afford novel insights into fundamental biological problems but may also enable new models for disease and suggest possible routes to therapeutic intervention. In particular, localized, genetic, and small-molecule-controlled caspase activation has the potential to target the desired cell type in a tissue. Suppression of caspase activation is one of the hallmarks of cancer and thus there has been significant enthusiasm for generating ...

As one of the Imperiums many staging grounds for the forces serving in the Great Crusade, the verdant world of Tallarn has long served as a transfer point for vast numbers of military personnel and their war machines. Now, destroyed by a deadly virus-bomb attack launched by the battered Iron Warriors fleet, the entire world is reduced to a toxic wasteland where the survivors must fight to defend what little remains of their home. The remnants of the once-mighty Jurnian 701st armoured regiment emerge from their underground shelters, and the opening movements of the Battle of Tallarn begin... ...

- It has been identified as one of the ''effector'' caspases (which include caspase 3, 6, 7) that are cleaved by ''initiator'' caspases (which include caspase 8, 9) into active form, and then, in turn, cleave various cellular proteins for apoptosis. (acris-antibodies.com)
- The current model of apoptosis holds that upstream signals lead to activation of downstream effector caspases. (sciencemag.org)
- The endothelial monocyte-activating polypeptide II (EMAP II) is a substrate for caspase-7. (acris-antibodies.com)
- Specific activity of caspase-3 or -7 can then be analyzed using the common caspase-3/7 substrate DEVD-AFC. (promokine.info)
- DFFA is the substrate for caspase-3 and triggers DNA fragmentation during apoptosis. (wikipedia.org)
- Recombinant protein encompassing a sequence within the C-terminus region of human Caspase 7. (genetex.com)
- Additionally we are shipping Caspase 7 Kits (60) and Caspase 7 Proteins (25) and many more products for this protein. (antibodies-online.com)
- Casp ase-7 (also known as Mch-3 / ICE-LAP3 / CMH-1) is a 35 kDa protein that has the highest similarity to caspase-3 (52% amino acid identity) among all caspase members. (acris-antibodies.com)
- Caspases orchestrate the organized death of the cell by cleaving a small but specific complement of protein substrates. (jneurosci.org)
- Caspase 3 is responsible for cellular differentiation, although it is unclear how this kind of protein can promote the cell apoptosis. (wikipedia.org)
- Hello all, I recently purchased a Caspase 3/7 Glo assay kit from Promega for apoptosis detection.My assay was done with HEK293 cells which were stimulated with Etoposide.I performed the assay exactly described in the protocol,and detected the luminescence with our Luminoskan Ascent luminometer. (protocol-online.org)
- I used etoposide to treat my cells for different time,and i also use different concentration.I also use the caspase 3/7 glo assay kit from promega. (protocol-online.org)
- The EarlyTox ™ Caspase-3/7 R110 Assay Kit provides a single-step, homogenous assay that is specifically designed for microplate readers. (moleculardevices.com)
- In this application note we report the use of the EarlyTox Caspase-3/7 R110 Assay Kit in combination with SpectraMax ® fluorescence microplate readers . (moleculardevices.com)
- Moreover, we show that, in contrast to the human enzymes, mouse caspase-7 is as efficient as caspase-3 at cleaving and thus inactivating ICAD (inhibitor of caspase-activated DNase), the inhibitor of apoptotic DNA fragmentation. (jneurosci.org)
- Per usual in non-apoptotic growing cells caspase activated dnase is held in check inactivated in the cytoplasm thanks to the association with its inhibitor, inhibitor of caspase-activated DNase (ICAD) also known as DNA fragmentation factor 45 kDa (DFF45). (wikipedia.org)
- DFFA is encoded by an alternatively encrypted mRNAs originating two distinct forms: short (ICAD-S) and long (ICAD-L), which act like a specific chaperone ensuring the correct CAD's folding Besides, it contains two aspartic acid residues (Asp117 and Asp224) where CAD is identified and, consequently, it stays bounded until Caspase-3 splits this union. (wikipedia.org)
- Lysates from control (lanes 1-3) and camptothecin-treated Jurkat cells (lanes 4-6) were probed with anti-human caspase-7 (clone 8-1-47, ABIN967331) at the following concentrations: 0.25 (lanes 1,4), 0.125 (lanes 2,5) and 0.062 µg/ml (lanes 3,6). (antibodies-online.com)
- Lysates from control (lane 1) or camptothecin-treated Jurkat cells (lane 2) were each immunoprecipitated with anti-human caspase-7 (clone 8-1-47) and western blotted with anti-human caspase-7 (clone 8-1-47). (antibodies-online.com)
- Recent study says that in Fas-mediated hepatocyte apoptosis, active caspase-7 is associated almost exclusivel y with the mitochondrial and microsomal fractions, whereas active caspase-3 is confined primarily to the cytosol. (acris-antibodies.com)
- We conclude that caspases 3 and 7 are critical mediators of mitochondrial events of apoptosis. (sciencemag.org)
- Abstract: Caspase-independent, non-apoptotic cell death in ischemic heart disease is considered to be one of the important therapeutic targets, however, the detailed mechanisms of this cell death process are not clear. (osti.gov)
