Context: Papillary thyroid cancer (PTC) is the second most common cancer in females in Saudi Arabia. However, the pathogenesis of PTC is still not fully elucidated. Objective: To identify potential genes that play important role in progression of PTC, we studied the role of X-linked inhibitor of apoptosis protein (XIAP) as a potential prognostic marker and therapeutic target in a large cohort of PTC samples and cell lines.Design: A DNA microarray chip was used to screen for gene copy number. XIAP expression was assessed by immunohistochemistry in a tissue microarray format on a cohort of 1022 clinical samples. In vitro and in vivo studies were performed using Embelin and/or LY294002 on PTC cell lines. Results: XIAP was found to be amplified in 14 of 29 and overexpressed in 48.8% of PTC cases. XIAP overexpression was significantly associated with old age, extrathyroidal extension, tumor size, nodal involvement, tall-cell variant, advanced stage disease, and significantly poor disease-free survival (P =

Apoptosis triggered through the intrinsic pathway by radiation and anti-neoplastic drugs is initiated by the activation of caspase-9. To elucidate control mechanisms in this pathway we used a range of synthetic and natural reagents. The inhibitory potency of acetyl-Asp-Glu-Val-Asp-aldehyde (Ac-DEVD-CHO), benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone (Z-VAD-FMK) and the endogenous caspase inhibitor X-chromosome-linked inhibitor of apoptosis protein (XIAP) against recombinant caspase-9 were predictive of the efficacy of these compounds in a cell-free system. However, the viral proteins CrmA and p35, although potent inhibitors of recombinant caspase-9, had almost no ability to block caspase-9 in this system. These findings were also mirrored in cell expression studies. We hypothesize that the viral inhibitors CrmA and p35 are excluded from reacting productively with the natural form of active caspase-9 in vivo, making the potency of inhibitors highly context-dependent. This is supported by ...
In rectal cancer patients routinely undergo neoadjuvant radio chemotherapy. Radio chemotherapy, and also radiotherapy alone, prior to surgery has been shown to reduce rates of local recurrence and improve disease free survival, when compared to surgery alone [29, 30]. Patients who experience complete pathological response to neo-adjuvant radio chemotherapy experience low incidence of local recurrence and distant metastases [7, 8]. A response to neo-adjuvant radio chemotherapy of 95 % or greater is associated with a good long term outcome for the patient [31]. Many patients respond poorly to neoadjuvant radio chemotherapy but the reason for this is currently not well understood [9, 10, 32]. We examined XIAP, cIAP-1, cIAP-2 and Smac protein levels in a cohort of rectal cancer patients to examine whether more chemo resistant tissue displayed an altered protein expression. We found that XIAP levels in tumour tissue increased as chemo resistance grades progressed from RCPath A, through RCPath B, to ...
Human X-linked inhibitor of apoptosis (XIAP) protein belongs to a family of apoptotic suppressor proteins that share a conserved motif, the baculovirus IAP repeat (BIR). The BIR motif is necessary for antiapoptotic function. XIAP plays a variety of other functional roles, such as also modulation of inflammatory signaling and immunity, mitogenic kinase signaling, cell proliferation, and copper homeostasis. XIAP acts as a caspase inhibitor by binding to the active site of caspase 3 and 7; it also inactivates caspase 9 by preventing it from forming active homodimers. Mutations in the XIAP gene are associated with X-linked lymphoproliferative syndrome. XIAP is also known as baculoviral IAP repeat-containing 4 (BIRC4), inhibitor of apoptosis protein 3 (IAP3), hIAP3, IAP-like protein, API3, ILP1, MIHA, and XLP2.. ...
X-linked inhibitor of apoptosis protein (XIAP), survivin, and BRUCE are members of the inhibitor-of-apoptosis protein (IAP) family known for their inhibitory effects on caspase activity and dysregulation of these molecules has widely been shown to cause embryonic defects and to promote tumorigenesis in human. Besides the anti-apoptotic functions, recent discoveries have revealed that XIAP, survivin, and BRUCE also exhibit regulatory functions for autophagy in cells. As the role of autophagy in human diseases has already been discussed extensively in different reviews; in this review, we will discuss the emerging autophagic role of XIAP, survivin, and BRUCE in cancer cells. We also provide an update on the anti-apoptotic functions and the roles in maintaining DNA integrity of these molecules. Second mitochondria-derived activator of caspases (Smac) is a pro-apoptotic protein and IAPs are the molecular targets of various Smac mimetics currently under clinical trials. Better understanding on the functions
Although an increased expression level of XIAP is associated with cancer cell metastasis, the underlying molecular mechanisms remain largely unexplored. To verify the specific structural basis of XIAP for regulation of cancer cell migration, we introduced different XIAP domains into XIAP−/− HCT116 cells, and found that reconstitutive expression of full length HA-XIAP and HA-XIAP ΔBIR, both of which have intact RING domain, restored β-Actin expression, actin polymerization and cancer cell motility. Whereas introduction of HA-XIAP ΔRING or H467A mutant, which abolished its E3 ligase function, did not show obvious restoration, demonstrating that E3 ligase activity of XIAP RING domain played a crucial role of XIAP in regulation of cancer cell motility. Moreover, RING domain rather than BIR domain was required for interaction with RhoGDI independent on its E3 ligase activity. To sum up, our present studies found that role of XIAP in regulating cellular motility was uncoupled from its caspase

The potent anti-apoptotic protein XIAP has substantial therapeutic potential in diseases where apoptosis plays a central role (9,10). Overexpression of XIAP has been shown to inhibit cell death in models of neurodegeneration including neuronal ischemia (11) and glaucoma (14), and inhibition of XIAP expression by an antisense approach to induce apoptosis has proven beneficial in preventing oncogenesis (22-24). Because apoptosis of islet β-cells is central to the pathogenesis of both autoimmune diabetes and failure of islet transplants, we hypothesized that XIAP, as an endogenous repressor of the terminal caspase pathway, may similarly confer protection to transplanted islet cells from allograft rejection. Using a simple model of adenoviral overexpression of XIAP, we found a marked protective effect of XIAP on cytokine-induced killing of β-cells in vitro and demonstrated that XIAP overexpression provides prolonged protection of islets transplanted into diabetic allogeneic recipients.. An ...
Inhibitor of apoptosis (IAP) proteins inhibit caspases, a function counteracted by IAP antagonists, insect Grim, HID, and Reaper and mammalian DIABLO/Smac. We now demonstrate that HtrA2, a mammalian homologue of the Escherichia coli heat shock-inducible protein HtrA, can bind to MIHA/XIAP, MIHB, and baculoviral OpIAP but not survivin. Although produced as a 50-kDa protein, HtrA2 is processed to yield an active serine protease with an N terminus similar to that of Grim, Reaper, HID, and DIABLO/Smac that mediates its interaction with XIAP. HtrA2 is largely membrane-associated in healthy cells, with a significant proportion observed within the mitochondria, but in response to UV irradiation, HtrA2 shifts into the cytosol, where it can interact with IAPs. HtrA2 can, like DIABLO/Smac, prevent XIAP inhibition of active caspase 3 in vitro and is able to counteract XIAP protection of mammalian NT2 cells against UV-induced cell death. The proapoptotic activity of HtrA2 in vivo involves both IAP binding and
MDM2 and X-linked inhibitor of apoptosis (XIAP) promote cancer cell survival by binding p53 and promoting its degradation and by inhibiting caspase activation to prevent apoptosis, respectively. Further, the RING domain of MDM2 can bind to the internal ribosome entry site (IRES) of XIAP mRNA transcripts to promote XIAP translation, increase MDM2 protein expression, and enhance resistance to apoptosis, suggesting a potential p53-independent role for MDM2 in enhancing cell survival. Gu and colleagues hypothesized that disrupting the interaction between MDM2 and XIAP would decrease expression of both proteins and enhance cancer cell apoptosis. A fluorescence polarization assay was developed for high-throughput screening of small-molecule inhibitors of XIAP IRES binding to the MDM2 RING domain. Of 141,394 small-molecule compounds tested, 8 candidates disrupted MDM2-XIAP binding, and 3 compounds selected for further study (MX3, MX11, and MX69) reduced protein expression of both MDM2 and XIAP when ...

XIAP, an associate from the inhibitor of apoptosis category of protein, is a crucial regulator of apoptosis. superfamily by their particular ligands. Activation of the receptors network marketing leads to the forming of the receptor-associated FADD (Fas-associated loss of life domain) complicated and following cleavage of caspase-8 and caspase-10. These prepared caspases after that cleave and activate caspase-3 and caspase-7 (Ashkenazi, 2008 ?). This aspect represents the convergence from the intrinsic and extrinsic pathways, as well as the unavoidable cleavage of downstream substrates leading to cell loss of life. XIAP (X-linked inhibitor of apoptosis) straight inhibits the upstream caspase-9 as well as the downstream caspase-3 and caspase-7, and for that reason controls important apoptotic checkpoints (Holcik & Korneluk, 2001 ?). The XIAP proteins consists of many domains, including three zinc-containing BIR (baculovirus IAP do it again) domains (BIR1, BIR2 and BIR3) and a C-terminal Band ...
3213 The mechanism and functional significance of XIAP and Mcl-1 down-regulation in human leukemia cells exposed to the HDAC inhibitor vorinostat and the CDK inhibitor flavopiridol was investigated. Combined exposure of U937 leukemia cells to marginally toxic concentrations of vorinostat and flavopiridol resulted in a marked increase in mitochondrial damage and apoptosis accompanied by pronounced reductions in XIAP and Mcl-1 mRNA and protein. Down-regulation of Mcl-1 and XIAP expression by vorinostat/flavopiridol was associated with enhanced inhibition of phosphorylation of RNA PolII and was amplified by caspase-mediated protein degradation. Chromatin immunoprecipitation (ChIP) analysis revealed that XIAP and Mcl-1 down-regulation were also accompanied by both decreased association of NF-κB (XIAP) and increased E2F1 association (Mcl-1) with their promoter regions, respectively. Ectopic expression of Mcl-1 but not XIAP partially protected cells from flavopiridol/vorinostat-mediated mitochondrial ...
TRAIL, a recently identified member of the tumor necrosis factor family, is capable of inducing apoptosis in various tumor cells (16, 17). The anti-neoplastic specificity of TRAIL warrants interest in the use of this compound in the clinic; however, in vitro resistance of some cancer cell lines might predict a limited role for TRAIL as a single agent. Hence, an active search for novel therapeutics directed against diverse molecular targets to overcome resistance of tumors to TRAIL is ongoing. A burgeoning literature shows that combining TRAIL with chemotherapeutic or certain signaling inhibitors results in robust enhancement of apoptosis, albeit via different mechanisms. Synergism of the combination was induced through enhanced induction of intrinsic apoptotic pathway, inhibition of pro-survival signaling via AKT and/or nuclear factor-κB, and down-regulation of inhibitor of apoptosis protein (XIAP). In the present study, we show for the first time that treatment of various cancer cells with ...
Background: Efforts to disrupt the establishment and maintenance of the latent reservoir have focused on the shock-and-kill therapeutic approach to reverse HIV latency from CD4+ T cells with subsequent killing of the infected cells. The X-linked inhibitor of apoptosis protein (XIAP) is up regulated in latently infected cell lines. In this study, we investigated whether this molecular signature existed in primary latently-infected resting central memory CD4+ T cells and whether this could be used to selectively target and kill latent HIV harboring cells.. Methods: CCL19-treated naïve CD4+ T cells isolated from HIV-uninfected donors were infected with HIV then expanded in the presence of IL2 for 12 d. Memory CD4+ T cells were then isolated and cultured in the presence of IL7 for a further 20 d then analyzed by flow cytometry. HIV integration was analyzed by Alu-LTR qPCR. Expression of XIAP was assessed using Western blotting. HIV p24 antigen was quantified by ELISA. Long-lived, resting memory ...
proteopedia link. proteopedia link. One of the CBI Molecules being studied in the University of Massachusetts Amherst Chemistry-Biology Interface Program at UMass Amherst and on display at the Molecular Playground. Caspase-9 belongs to a family of molecular scissors called cysteine aspartate proteases. These proteases are the facilitators of apoptosis, the highly process of programmed cell death which is an important cellular process critical for normal development and stability of an organism. Caspase-9 is regulated by controlling its multimeric state through monomer-dimer transitions. Caspase-9 exists as an inactive monomer and becomes active upon dimerization. It is in this dimeric state that caspase-9 can cut its intended protein partners (called substrates) at a specific amino acid sequence. X-linked inhibitors of apoptosis proteins, specifically the BIR3 domain, bind to monomeric caspase-9 to block dimerization thus preventing activation. ...
Supplementary MaterialsData_Sheet_1. by looking at with healthy individuals, higher levels of serum exosomal miR-92b-3p, let-7g-5p, miR-146b-5p, and miR-9-5p were found to be significantly associated with early-stage GC ( 0.05). Diagnostic power of the combined panels of the exosomal miRNAs or the combination of exosomal BAY 80-6946 supplier miRNAs and CEA outperformed that of single exosomal miRNA marker for establishing a diagnosis of early-stage GC. The combined diagnosis of exosomal miR-92b-3p + let-7g-5p + miR-146b-5p + miR-9-5p with CEA had the most powerful efficiency with an AUC up to 0.786. In addition, serum levels of exosomal miR-92b-3p were significantly associated with poor cohesiveness (= 0.0021), let-7g-5p and miR-146b-5p were significantly correlated with nerve infiltration (= 0.0234 and = 0.0126, respectively), and miR146b-5p was statistically correlated with tumor invasion depth in early-stage GC (= 0.0089). In conclusion, serum exosomal miR-92b-3p, -146b-5p, -9-5p, and ...

Within an apoptotic history, upon tension induction, a portion of the N-terminal area of HtrA proteases harboring the mitochondrial localization sign gets cleaved resulting in the forming of an adult enzyme, which is certainly subsequently translocated through the mitochondria towards the cytoplasm to mediate apoptosis frequently through both caspase-dependent and indie system [1,25C27]. HtrA2 and HtrA3 particularly bind and cleave XIAP (X-linked inhibitor of apoptosis) to cause the caspase-mediated intrinsic pathway [22,28C32]. While HtrA2 binds XIAP via the tetrapeptide IBM (AVPS residues) thats open on maturation, no such series has been described for HtrA3. Besides, their involvement in non-classical cell loss of life pathways continues to be hypothesized [25 also,26,33]. HtrA3, initial defined as a pregnancy-related serine ...

Background: Berberine (BBR) has gained considerable attention because of its anti-tumor activity. BBR can induce apoptosis of acute lymphoblastic leukemia (ALL) cells through the MDM2/p53 pathway. However, the effects of BBR on those ALL patients with p53 deficiency remain unclear.Results: We found that BBR reduced ALL cell viability and induced apoptosis in p53-null EU-4 and p53-mutant EU-6 cells by downregulating X-linked inhibitor of apoptosis protein (XIAP), which is increased in ALL tissues and cells. BBR-induced cell apoptosis was attenuated by inhibition of XIAP that was controlled by PIM-2. Mechanistic studies showed that BBR treatment induced an enhancement of miR-24-3p. PIM-2 is a direct target of miR-24-3p. Blockade of PIM-2 or miR-24-3p reversed BBR-induced cell apoptosis. In vivo studies, BBR remarkably alleviated leukemia conditions in a EU4 xenograft mouse model, whereas inhibition of miR-24-3p significantly reversed the effects of BBR in the leukemia condition.Conclusions: miR-24
BIRC7 (baculoviral IAP repeat containing 7), Authors: Dhiego Botelho Rigato, Paola Cristina Branco , Catarina Sofia Mateus Reis Silva, João Agostinho Machado-Neto, Letícia Veras Costa-Lotufo, Paula Christine Jimenez. Published in: Atlas Genet Cytogenet Oncol Haematol.
We report herein the role of XIAP, an antiapoptotic protein that can inhibit both mitochondrial and extrinsic pathways of apoptosis, to play a key role in therapeutic sensitivity in IBC cells. A distinct mechanism of increased expression of XIAP and survivin, key members of the BIRC/IAP protein family post-trastuzumab treatment, was observed in ErbB2-overexpressing SUM190PT IBC cells, an established ErbB2-overexpressing IBC line isolated from a primary tumor of an IBC patient (30). In contrast, decrease in tumor cell viability in response to treatment with the small-molecule ErbB2-targeting agent, GW583340, correlated with a significant decrease in XIAP and survivin abundance. Further, XIAP inhibition was only seen at concentrations wherein there was ,50% cell death.. Our data reveal that trastuzumab can bind effectively to cell surface ErbB2 and elicit a potent ADCC response in both sensitive SKBR3 non-IBC and resistant SUM190PT IBC cells (Fig. 6A and B, 1). Whether this immune-mediated ...
Members of the inhibitor of apoptosis (IAP) family of proteins are able to inhibit cell death following viral infection, during development or in cell lines in vitro. All IAP proteins bear one or more baculoviral IAP repeats (BIRs). Here we describe the solution structure of the third BIR domain from the mammalian IAP homolog B (MIHB/c-IAP-1). The BIR domain has a novel fold that is stabilized by zinc tetrahedrally coordinated by one histidine and three cysteine residues. The structure consists of a series of short alpha-helices and turns with the zinc packed in an unusually hydrophobic environment created by residues that are highly conserved among all BIRs.
SY26-01 The inhibitor of apoptosis (IAP) proteins are major regulators of apoptosis that bind to and inhibit caspases 3, 7, and/or 9. Overexpression of IAP proteins has been demonstrated to confer protection against a variety of pro apoptotic stimuli, including chemotherapies, and is a marker for poor prognosis in a variety of solid tumors and hematologic malignancies. All IAP proteins contain one to three copies of the baculoviral IAP repeat (BIR) domain, zinc-binding domains of about 80 amino acids, that are necessary for their interactions with a number of cytosolic target proteins, including activated caspases 3, 7, and/or 9. Antagonism of the IAP protein mediated inhibition of these caspases is required for caspase dependent cell death, and can be achieved by the mitochondrial protein second mitochondria derived activator of caspases/direct IAP binding protein with low pI (Smac/DIABLO), which is released into the cytoplasm in response to pro apoptotic stimuli. The pro apoptotic function of ...

article{9ddf7583-09ff-4701-b27d-66a382e51d06, abstract = {,p,Second mitochondria-derived activator of caspase (SMAC) mimetics (SMs) are selective antagonists of the inhibitor of apoptosis proteins (IAPs), which activate noncanonical NF-B signaling and promote tumor cell death. Through gene expression analysis, we found that treatment of CD4,sup,+,/sup, T cells with SMs during T helper 17 (T,sub,H,/sub,17) cell differentiation disrupted the balance between two antagonistic transcription factor modules. Moreover, proteomics analysis revealed that SMs altered the abundance of proteins associated with cell cycle, mitochondrial activity, and the balance between canonical and noncanonical NF-B signaling. Whereas SMs inhibited interleukin-17 (IL-17) production and ameliorated T,sub,H,/sub,17 cell-driven inflammation, they stimulated IL-22 secretion. Mechanistically, SM-mediated activation of NF-B-inducing kinase (NIK) and the transcription factors RelB and p52 directly suppressed Il17a expression and ...

Survivin antibody (baculoviral IAP repeat containing 5) for ELISA, ICC/IF, WB. Anti-Survivin pAb (GTX31651) is tested in Human samples. 100% Ab-Assurance.
Regulators of apoptosis are thought to work in concert, but the molecular interactions of this process are not understood. Here, we show that in response to cell death stimulation, survivin, a member of the inhibitor of apoptosis (IAP) gene family, associates with another IAP protein, XIAP, via conserved baculovirus IAP repeats. Formation of a survivin-XIAP complex promotes increased XIAP stability against ubiquitination/proteasomal destruction and synergistic inhibition of apoptosis, which is abolished in XIAP(-/-) cells. Therefore, orchestration of an IAP-IAP complex regulates apoptosis.
We next generated rabbit polyclonal antibodies against bacterially expressed and purified GST fusion proteins of each of the three rat IAPs and used these antibodies to examine the rat IAP distribution in multiple tissues (Figure 2). The protein samples were prepared from fresh adult rat tissues and analyzed by Western blot. The rat IAP-1 was expressed in all tissues examined with the exception of brain, liver and thymus. The expression of IAP-2 was observed in all tissues except brain, lung and thymus. In contrast, IAP-3 was found in all tissues examined. In the majority of the tissues we observed one prominent protein band of the expected molecular mass for each of the rat IAPs. Several tissues (intestine, kidney, spleen, testes), however, showed smaller protein bands of varying intensity which could be detected with the anti-iap-1 and anti-iap-2 antibodies, but not the anti-iap-3 antibody. The corresponding shorter mRNA transcripts that could give rise to smaller protein bands were only ...
IAP (Inhibitors of Apoptosis) is a family of functionally and structurally related proteins, which serve as endogenous inhibitors of programmed cell death (apoptosis). A common feature of all IAPs is the presence of a BIR in one to three copies. The human IAP family consists of 8 members, and IAP homologs have been identified in numerous organisms. The members of the IAPs included IAPs, Cp-IAP, Op-IAP, XIAP, c-IAPl, C-IAP2, NAIP, Livin and Survivin. The best characterized IAP is XIAP, which binds caspase-9, caspase-3 and caspase 7, thereby inhibiting their activation and preventing apoptosis. Also cIAP1 and cIAP2 have been shown to bind caspases, although how the IAPs inhibit apoptosis mechanistically at the molecular level is not completely understood.. ...
