Proto-Oncogene Proteins c-bcl-2
Membrane proteins encoded by the BCL-2 GENES and serving as potent inhibitors of cell death by APOPTOSIS. The proteins are found on mitochondrial, microsomal, and NUCLEAR MEMBRANE sites within many cell types. Overexpression of bcl-2 proteins, due to a translocation of the gene, is associated with follicular lymphoma.
bcl-2-Associated X Protein
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
Apoptosis Regulatory Proteins
Iron Regulatory Protein 1
A multifunctional iron-sulfur protein that is both an iron regulatory protein and cytoplasmic form of aconitate hydratase. It binds to iron regulatory elements found on mRNAs involved in iron metabolism and regulates their translation. Its RNA binding ability and its aconitate hydrolase activity are dependent upon availability of IRON.
A family of intracellular CYSTEINE ENDOPEPTIDASES that play a role in regulating INFLAMMATION and APOPTOSIS. They specifically cleave peptides at a CYSTEINE amino acid that follows an ASPARTIC ACID residue. Caspases are activated by proteolytic cleavage of a precursor form to yield large and small subunits that form the enzyme. Since the cleavage site within precursors matches the specificity of caspases, sequential activation of precursors by activated caspases can occur.
Iron Regulatory Protein 2
Inhibitor of Apoptosis Proteins
A conserved class of proteins that control APOPTOSIS in both VERTEBRATES and INVERTEBRATES. IAP proteins interact with and inhibit CASPASES, and they function as ANTI-APOPTOTIC PROTEINS. The protein class is defined by an approximately 80-amino acid motif called the baculoviral inhibitor of apoptosis repeat.

Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
In Situ Nick-End Labeling
An in situ method for detecting areas of DNA which are nicked during APOPTOSIS. Terminal deoxynucleotidyl transferase is used to add labeled dUTP, in a template-independent manner, to the 3 prime OH ends of either single- or double-stranded DNA. The terminal deoxynucleotidyl transferase nick end labeling, or TUNEL, assay labels apoptosis on a single-cell level, making it more sensitive than agarose gel electrophoresis for analysis of DNA FRAGMENTATION.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
X-Linked Inhibitor of Apoptosis Protein
Apoptosis Inducing Factor
A flavoprotein that functions as a powerful antioxidant in the MITOCHONDRIA and promotes APOPTOSIS when released from the mitochondria. In mammalian cells AIF is released in response to pro-apoptotic protein members of the bcl-2 protein family. It translocates to the CELL NUCLEUS and binds DNA to stimulate CASPASE-independent CHROMATIN condensation.
CASP8 and FADD-Like Apoptosis Regulating Protein
An APOPTOSIS-regulating protein that is structurally related to CASPASE 8 and competes with CASPASE 8 for binding to FAS ASSOCIATED DEATH DOMAIN PROTEIN.

Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes. (King & Stansfield, A Dictionary of Genetics, 4th ed)

The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Fas Ligand Protein
A transmembrane protein belonging to the tumor necrosis factor superfamily that was originally discovered on cells of the lymphoid-myeloid lineage, including activated T-LYMPHOCYTES and NATURAL KILLER CELLS.

Gene Expression Regulation
Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
Injuries to DNA that introduce deviations from its normal, intact structure and which may, if left unrepaired, result in a MUTATION or a block of DNA REPLICATION. These deviations may be caused by physical or chemical agents and occur by natural or unnatural, introduced circumstances. They include the introduction of illegitimate bases during replication or by deamination or other modification of bases; the loss of a base from the DNA backbone leaving an abasic site; single-strand breaks; double strand breaks; and intrastrand (PYRIMIDINE DIMERS) or interstrand crosslinking. Damage can often be repaired (DNA REPAIR). If the damage is extensive, it can induce APOPTOSIS.
Cytochrome c Group
Proto-Oncogene Proteins c-akt
Protein Structure, Tertiary
The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.
Gene Expression Regulation, Neoplastic

Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.
The pathological process occurring in cells that are dying from irreparable injuries. It is caused by the progressive, uncontrolled action of degradative ENZYMES, leading to MITOCHONDRIAL SWELLING, nuclear flocculation, and cell lysis. It is distinct it from APOPTOSIS, which is a normal, regulated cellular process.
A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
A gene silencing phenomenon whereby specific dsRNAs (RNA, DOUBLE-STRANDED) trigger the degradation of homologous mRNA (RNA, MESSENGER). The specific dsRNAs are processed into SMALL INTERFERING RNA (siRNA) which serves as a guide for cleavage of the homologous mRNA in the RNA-INDUCED SILENCING COMPLEX. DNA METHYLATION may also be triggered during this process.

A long pro-domain caspase that contains a caspase recruitment domain in its pro-domain region. Activation of this enzyme can occur via the interaction of its caspase recruitment domain with CARD SIGNALING ADAPTOR PROTEINS.

A semisynthetic derivative of PODOPHYLLOTOXIN that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle.
Decreased expression of the pro-apoptotic protein Par-4 in renal cell carcinoma. (1/5488)Par-4 is a widely expressed leucine zipper protein that confers sensitization to apoptosis induced by exogenous insults. Because the expression of genes that promote apoptosis may be down-regulated during tumorigenesis, we sought to examine the expression of Par-4 in human tumors. We present here evidence that Par-4 protein levels were severely decreased in human renal cell carcinoma specimens relative to normal tubular cells. Replenishment of Par-4 protein levels in renal cell carcinoma cell lines conferred sensitivity to apoptosis. Because apoptosis may serve as a defense mechanism against malignant transformation or progression, decreased expression of Par-4 may contribute to the pathophysiology of renal cell carcinoma.

Characterization of a novel mouse cDNA, ES18, involved in apoptotic cell death of T-cells. (2/5488)Using the modified screening approach in combination with expressed sequence tags, we have identified several novel cDNAs from mouse embryonic stem (ES) cells, whose expression is tissue-restricted and/or developmentally regulated. One of the cDNAs, ES18, is preferentially expressed in lymph node and thymus, and contains noteworthy features of transcriptional regulator. The expression of ES18 transcript was selectively regulated during the apoptosis of T-cell thymoma S49.1 induced by several stimuli. Interestingly, the ES18 transcript was differently regulated in the mutually antagonistic process, between dexamethasone- and A23187-induced cell death of T-cells. Moreover, the message level of ES18 was selectively enhanced by staurosporine, a broad protein kinase inhibitor, but not by other protein kinase inhibitors such as GF109203X and H89. In addition, ES18 transcript was induced by C2-ceramide, which is a mediator of both dexamethasone- and staurosporine-induced apoptotic signaling. We further showed that transient overexpression of ES18 in mouse T-cell lymphoma increased the apoptotic cell death. These data suggest that ES18 may be selectively involved in specific apoptotic processes in mouse T-cells. (+info)
Functional analysis of TRAIL receptors using monoclonal antibodies. (3/5488)mAbs were generated against the extracellular domain of the four known TNF-related apoptosis-inducing ligand (TRAIL) receptors and tested on a panel of human melanoma cell lines. The specificity of the mAb permitted a precise evaluation of the TRAIL receptors that induce apoptosis (TRAIL-R1 and -R2) compared with the TRAIL receptors that potentially regulate TRAIL-mediated apoptosis (TRAIL-R3 and -R4). Immobilized anti-TRAIL-R1 or -R2 mAbs were cytotoxic to TRAIL-sensitive tumor cells, whereas tumor cells resistant to recombinant TRAIL were also resistant to these mAbs and only became sensitive when cultured with actinomycin D. The anti-TRAIL-R1 and -R2 mAb-induced death was characterized by the activation of intracellular caspases, which could be blocked by carbobenzyloxy-Val-Ala-Asp (OMe) fluoromethyl ketone (zVAD-fmk) and carbobenzyloxy-Ile-Glu(OMe)-Thr-Asp (OMe) fluoromethyl ketone (zIETD-fmk). When used in solution, one of the anti-TRAIL-R2 mAbs was capable of blocking leucine zipper-human TRAIL binding to TRAIL-R2-expressing cells and prevented TRAIL-induced death of these cells, whereas two of the anti-TRAIL-R1 mAbs could inhibit leucine zipper-human TRAIL binding to TRAIL-R1:Fc. Furthermore, use of the blocking anti-TRAIL-R2 mAb allowed us to demonstrate that the signals transduced through either TRAIL-R1 or TRAIL-R2 were necessary and sufficient to mediate cell death. In contrast, the expression of TRAIL-R3 or TRAIL-R4 did not appear to be a significant factor in determining the resistance or sensitivity of these tumor target cells to the effects of TRAIL. (+info)
Involvement of TNF-related apoptosis-inducing ligand in human CD4+ T cell-mediated cytotoxicity. (4/5488)TNF-related apoptosis-inducing ligand (TRAIL) has been identified as a member of the TNF family that induces apoptosis in a variety of tumor cells, but its physiological functions are largely unknown. In the present study, we examined the expression and function of TRAIL in human CD4+ T cell clones by utilizing newly established anti-human TRAIL mAbs. Human CD4+ T cell clones, HK12 and 4HM1, exhibited perforin-independent and Fas ligand (FasL)-independent cytotoxicity against certain target cells, including T lymphoma (Jurkat) and keratinocyte (HaCaT) cell lines, which are susceptible to TRAIL-mediated cytotoxicity. In contrast to FasL, the expression of which was inducible upon anti-CD3 stimulation, TRAIL was constitutively expressed on HK12 and 4HM1 cells, and no further increase was observed after anti-CD3 stimulation. Spontaneous cytotoxic activities of resting HK12 and 4HM1 cells against Jurkat and HaCaT cells were blocked by anti-TRAIL mAb but not by anti-FasL mAb, and bystander cytotoxic activities of anti-CD3-stimulated HK12 and 4HM1 cells were abolished by the combination of anti-TRAIL and anti-FasL mAbs. These results indicate a differential regulation of TRAIL and FasL expression on human CD4+ T cell clones and that TRAIL constitutes an additional pathway of T cell-mediated cytotoxicity. (+info)
The cell death-promoting gene DP5, which interacts with the BCL2 family, is induced during neuronal apoptosis following exposure to amyloid beta protein. (5/5488)DP5, which contains a BH3 domain, was cloned as a neuronal apoptosis-inducing gene. To confirm that DP5 interacts with members of the Bcl-2 family, 293T cells were transiently co-transfected with DP5 and Bcl-xl cDNA constructs, and immunoprecipitation was carried out. The 30-kDa Bcl-xl was co-immunoprecipitated with Myc-tagged DP5, suggesting that DP5 physically interacts with Bcl-xl in mammalian cells. Previously, we reported that DP5 is induced during neuronal apoptosis in cultured sympathetic neurons. Here, we analyzed DP5 gene expression and the specific interaction of DP5 with Bcl-xl during neuronal death induced by amyloid-beta protein (A beta). DP5 mRNA was induced 6 h after treatment with A beta in cultured rat cortical neurons. The protein encoded by DP5 mRNA showed a specific interaction with Bcl-xl. Induction of DP5 gene expression was blocked by nifedipine, an inhibitor of L-type voltage-dependent calcium channels, and dantrolene, an inhibitor of calcium release from the endoplasmic reticulum. These results suggested that the induction of DP5 mRNA occurs downstream of the increase in cytosolic calcium concentration caused by A beta. Moreover, DP5 specifically interacts with Bcl-xl during neuronal apoptosis following exposure to A beta, and its binding could impair the survival-promoting activities of Bcl-xl. Thus, the induction of DP5 mRNA and the interaction of DP5 and Bcl-xl could play significant roles in neuronal degeneration following exposure to A beta. (+info)
TWEAK induces angiogenesis and proliferation of endothelial cells. (6/5488)TWEAK is a recently described member of the Tumor Necrosis Factor (TNF) ligand family whose transcripts are present in a wide variety of human tissues (Chicheportiche, Y., Bourdon, P. R., Xu, H., Hsu Y. M., Scott, H., Hession, C., Garcia, I., and Browning, J. L. (1997) J. Biol. Chem. 272, 32401-32410). TWEAK is a weak inducer of apoptosis in transformed cells when administered with interferon-gamma or cycloheximide (Chicheportiche, Y., Bourdon, P. R., Xu, H., Hsu Y. M., Scott, H., Hession, C., Garcia, I., and Browning, J. L. (1997) J. Biol. Chem. 272, 32401-32410; Masters, S. A., Sheridan, J. P., Pitti, R. M., Brush, A. G., and Ashkenazi, A. (1998) Curr. Biol. 8, 525-528) and also promotes IL-8 secretion in cultured cells. We report here that picomolar concentrations of recombinant soluble TWEAK induce proliferation in a variety of normal human endothelial cells and in aortic smooth muscle cells and reduce culture requirements for serum and growth factors. Blocking antibodies to Vascular Endothelial Growth Factor (VEGF) do not significantly inhibit TWEAK-induced proliferation, indicating that TWEAK does not function indirectly through up-regulation of VEGF. Pellets containing TWEAK induce a strong angiogenic response when implanted in rat corneas, suggesting a role for TWEAK in vasculature formation in vivo. (+info)
The ubiquitin-homology protein, DAP-1, associates with tumor necrosis factor receptor (p60) death domain and induces apoptosis. (7/5488)The tumor necrosis factor receptor, p60 (TNF-R1), transduces death signals via the association of its cytoplasmic domain with several intracellular proteins. By screening a mammalian cDNA library using the yeast two-hybrid cloning technique, we isolated a ubiquitin-homology protein, DAP-1, which specifically interacts with the cytoplasmic death domain of TNF-R1. Sequence analysis reveals that DAP-1 shares striking sequence homology with the yeast SMT3 protein that is essential for the maintenance of chromosome integrity during mitosis (Meluh, P. B., and Koshland, D. (1995) Mol. Biol. Cell 6, 793-807). DAP-1 is nearly identical to PIC1, a protein that interacts with the PML tumor suppressor implicated in acute promyelocytic leukemia (Boddy, M. N., Howe, K., Etkin, L. D., Solomon, E., and Freemont, P. S. (1996) Oncogene 13, 971-982), and the sentrin protein, which associates with the Fas death receptor (Okura, T., Gong, L., Kamitani, T., Wada, T., Okura, I., Wei, C. F., Chang, H. M., and Yeh, E. T. (1996) J. Immunol. 157, 4277-4281). The in vivo interaction between DAP-1 and TNF-R1 was further confirmed in mammalian cells. In transient transfection assays, overexpression of DAP-1 suppresses NF-kappaB/Rel activity in 293T cells, a human kidney embryonic carcinoma cell line. Overexpression of either DAP-1 or sentrin causes apoptosis of TNF-sensitive L929 fibroblast cell line, as well as TNF-resistant osteosarcoma cell line, U2OS. Furthermore, the dominant negative Fas-associated death domain protein (FADD) protein blocks the cell death induced by either DAP-1 or FADD. Collectively, these observations highly suggest a role for DAP-1 in mediating TNF-induced cell death signaling pathways, presumably through the recruitment of FADD death effector. (+info)
Alternative splicing determines the intracellular localization of the novel nuclear protein Nop30 and its interaction with the splicing factor SRp30c. (8/5488)We report on the molecular cloning of a novel human cDNA by its interaction with the splicing factor SRp30c in a yeast two-hybrid screen. This cDNA is predominantly expressed in muscle and encodes a protein that is present in the nucleoplasm and concentrated in nucleoli. It was therefore termed Nop30 (nucleolar protein of 30 kDa). We have also identified a related cDNA with a different carboxyl terminus. Sequencing of the NOP gene demonstrated that both cDNAs are generated by alternative 5' splice site usage from a single gene that consists of four exons, spans at least 1800 nucleotides, and is located on chromosome 16q21-q23. The alternative 5' splice site usage introduces a frameshift creating two different carboxyl termini. The carboxyl terminus of Nop30 is rich in serines and arginines and has been found to target the protein into the nucleus, whereas its isoform is characterized by proline/glutamic acid dipeptides in its carboxyl terminus and is predominantly found in the cytosol. Interaction studies in yeast, in vitro protein interaction assays, and co-immunoprecipitations demonstrated that Nop30 multimerizes and binds to the RS domain of SRp30c but not to other splicing factors tested. Overexpression of Nop30 changes alternative exon usage in preprotachykinin and SRp20 reporter genes, suggesting that Nop30 influences alternative splice site selection in vivo. (+info)
Expression pattern of the apoptosis-stimulating protein of p53 family in p53 + human breast cancer cell lines | Cancer Cell...
The apoptosis-stimulating protein of p53 (ASPP) family comprises three members, namely, ASPP1, ASPP2, and iASPP. They regulate the promotive effect of p53 on apoptosis. Breast cancer (BC) remains as one of the leading causes of cancer or cancer-related mortality among women. However, the relationship between the ASPP family members and p53, as well as the dissemination and expression pattern of ASPP family members in p53+ BC, has not been elucidated. Our objectives are to detect the expression of ASPP family members in p53+ BC cell lines and determine its significance in tumor cell apoptosis. The mRNA expression of ASPP family members in five p53+ BC cell lines was detected through RT-PCR and assayed using Quality-one software. The p53 protein expression was detected by immunohistochemistry. Afterward, the apoptosis indices of the five BC cell lines were detected by flow cytometry. The iASPP mRNA was expressed in Bcap-37, MCF-7, and HBL-100. Compared with the human peripheral blood mononuclear cells,

Regulation of heat-induced cell death by the pro-apoptotic Bcl-2 family protein PUMA
Apoptosis is often deregulated in a number of human diseases. Hyperthermia induced apoptosis is a model system for studying the consequences of protein misfolding and is mediated by the Bcl-2 family of proteins. This family consists of both pro-apoptotic and anti-apoptotic members that control mitochondrial integrity. The BH3-only pro-apoptotic members are strong inducers of apoptosis. Our examination of the effect of hyperthermia on the BH3-only protein PUMA, found that although protein levels were rapidly depleted following exposure to heat shock, levels of PUMA mRNA increased. This suggests that post-transcriptional mechanisms control the translation of PUMA mRNA in heat-shocked cells. We therefore examined whether miRNA-mediated inhibition of PUMA translation was responsible for the loss of PUMA protein. We provide evidence for the role of miR-24-2 and miR-29a as mediators of this repression and that strategies directed at the inhibition of these miRNAs could be effective in sensitizing ...

Dopamine is a neurotransmitter in circuits that convey reward and motivation, and abnormalities in dopamine signaling have been associated with mental illness. In particular, reduced function of the D2-type dopamine receptor (D2DR) is thought to contribute to schizophrenia, addiction, and mood disorders. Park et al. used a yeast two-hybrid screen to uncover prostate apoptosis response 4 (Par-4) as a binding partner for D2DR. In striatal neurons from mice that expressed a mutant form of Par-4 (in which the domain mediating the interaction with D2DR had been deleted), activation of signaling through cAMP was disrupted. Furthermore, behavioral tests of the mutant mice showed a depression-like phenotype, but no effects on measures of anxiety. Beaulieu et al. examined another signaling pathway emanating from D2DR, and they find that β-arrestin 2 is important in mediating the behavioral effects of dopamine. In wild-type mice, β-arrestin 2 was shown to associate with protein phosphatase 2a (PP2A) and ...

Death-associated protein kinase (DAPK) family modulators: Current and future therapeutic outcomes - International Natural...
Abstract. Serine/threonine kinases (STKs) represent the majority of discovered kinases to date even though a few Food and Drug Administration approved STKs inhibitors are reported. The third millennium came with the discovery of an important group of STKs that reshaped our understanding of several biological signaling pathways. This family was named death-associated protein kinase family (DAPK family). DAPKs comprise five members (DAPK1, DAPK2, DAPK3, DRAK1, and DRAK2) and belong to the calcium/calmodulin-dependent kinases domain. As time goes on, the list of biological functions of this family is constantly updated. The most extensively studied member is DAPK1 (based on the publications number and Protein Data Bank reported crystal structures) that plays fundamental biological roles depending on the cellular context. DAPK1 regulates apoptosis, autophagy, contributes to the pathogenesis of Alzheimers disease, acts as a tumor suppressor, inhibits metastasis, mediates the body responses to viral ...
Tumor suppressor death-associated protein kinase is required for full IL-1β production. - Semantic Scholar
Interleukin-1β (IL-1β) is critical for inflammation and control of infection. The production of IL-1β depends on expression of pro-IL-1β and inflammasome component induced by inflammatory stimuli, followed by assembly of inflammasome to generate caspase-1 for cleavage of pro-IL-1β. Here we show that tumor suppressor death-associated protein kinase (DAPK) deficiency impaired IL-1β production in macrophages. Generation of tumor necrosis factor-α in macrophages, in contrast, was not affected by DAPK knockout. Two tiers of defects in IL-1β generation were found in DAPK-deficient macrophages: decreased pro-IL-1β induction by some stimuli and reduced caspase-1 activation by all inflammatory stimuli examined. With a normal NLRP3 induction in DAPK-deficient macrophages, the diminished caspase-1 generation is attributed to impaired inflammasome assembly. There is a direct binding of DAPK to NLRP3, suggesting an involvement of DAPK in inflammasome formation. We further illustrated that the formation of
Epigenetic down-regulation of death-associated protein kinase in lung cancers. - Early Detection Research Network
Death-associated protein kinase (DAPK) is a pro-apoptotic serine/threonine kinase involved in apoptosis. Aberrant methylation of DAPK was reported in lung cancers by methylation-specific PCR. However, we were unable to relate methylation with gene silencing with the same methodology. Our goals were to develop a methodology that related methylation with gene silencing and use it to study the state of the gene in lung cancers.. Using a semiquantitative real-time reverse transcription-PCR, DAPK expression was lower in lung cancers than in corresponding nonmalignant bronchial epithelial cells in five of six primary short-term cultures. In continuous cell lines, mRNA expression was down-regulated, as well as compared with nonmalignant bronchial epithelial cells, and its protein was not detected by Western blotting in 17 of 23 (74%) cell lines. We investigated methylation status of 5 flanking region of DAPK by combined bisulfite restriction analysis and bisulfited DNA sequencing. Aberrant methylation ...
A novel inhibitor of zipper-interacting protein kinase (ZIPK) was utilized to examine the involvement of ZIPK in the regulation of smooth muscle contraction. Pre-treatment of de-endothelialized rat caudal arterial smooth muscle strips with the pyrazolo[3,4-d]pyrimidinone inhibitor HS38 decreased the velocity of contraction (time to reach half-maximal force) induced by the phosphatase inhibitor calyculin A in the presence of Ca2+ without affecting maximal force development. This effect was reversed following washout of HS38 and correlated with a reduction in the rate of phosphorylation of LC20 (myosin 20-kDa regulatory light chains) but not of CPI-17 (protein kinase C-potentiated inhibitory protein for myosin phosphatase of 17 kDa), Par-4 (prostate apoptosis response-4) or MYPT1 (myosin phosphatase targeting subunit 1), all of which have been implicated in the regulation of vascular contractility. A structural analog of HS38, with inhibitory activity towards PIM3 kinase but not ZIPK, had no ...

Negative regulator of epidermal barrier repair and innate immune responses to wounding (PubMed:19164535, PubMed:27661253). The role in epidermal tissue integrity and wound healing is established through the inhibition of epidermal microtubule stability, possibly via the negative regulation of the microtubule minus-end binding protein ptrn-1 (PubMed:27661253). In epidermis, prevents expression of specific unc-44 isoforms probably by promoting nuclear localization of pinn-1, which in turn may affect sydn-1-ssup-72-mediated regulation of alternative polyadenylation of unc-44 mRNA (PubMed:28087624). Appears to act downstream of or in parallel to muscarinic signaling in the regulation of autophagy (PubMed:17785524).
BAC-mediated transgenic expression of fluorescent autophagic protein Beclin 1 reveals a role for Beclin 1 in lymphocyte...
Beclin 1/Atg6 is an essential component of the evolutionary conserved PtdIns(3)-kinase (Vps34) protein complex that regulates macroautophagy (autophagy) in eukaryotic cells and also interacts with antiapoptotic Bcl-2 family members, Bcl-2, and Bcl-x(L). To elucidate the physiological function of Beclin 1, we generated transgenic mice producing a green fluorescent Beclin 1 protein (Beclin 1-GFP) under Beclin 1 endogenous regulation. The beclin 1-GFP transgene is functional because it completely rescues early embryonic lethality in beclin 1-deficient mice. The transgenic mice appear normal, with undetected change in basal autophagy levels in different tissues, despite the additional expression of functional Beclin 1-GFP. Staining of Beclin 1-GFP shows mostly diffuse cytoplasmic distribution in various tissues. Detailed analysis of the transgene expression by flow cytometry reveals a Bcl-2-like biphasic expression pattern in developing T and B cells, as well as differential regulation of expression in

Silencing Cell Death? | Science Signaling
Although most cases of chronic lymphocytic leukemia (CLL, one of the most common forms of adult leukemia) are sporadic, perhaps 10 to 20% are familial (see Debatin). Noting that aberrant DNA methylation--and thereby abnormal gene silencing--was emerging as a factor in CLL, Raval et al. performed quantitative high-throughput analysis to investigate DNA methylation in the CpG island of DAPK1 (death-associated protein kinase 1). DNA methylation of DAPK1 gene, which encodes a serine/threonine kinase implicated in promoting apoptosis in response to Fas, interferon-γ, and TNF-α, was increased in peripheral blood mononuclear cells and CD19+ B cells from people with CLL compared with that in cells from healthy volunteers. Reverse transcription polymerase chain reaction analysis indicated that DAPK1 expression was decreased in CD19+ CLL cells compared with that in B lymphocytes, and methylation reduced activity of a gene reporter containing a region of the DAPK1 promoter. Genome-wide linkage analysis ...

Death-associated protein kinase (DAPK) is really a calmodulin-regulated serine/threonine kinase and possesses apoptotic and tumor-suppressive functions. in regulating cell polarity during migration, which might work as well as its apoptotic function to suppress tumor development. Intro Cell migration is vital for many natural procedures, AZD4547 including embryonic advancement, wound curing, and immune monitoring. Migration is really a complicated and extremely coordinated process that will require a cell to polarize, expand protrusions in direction of motion, type adhesions at the best advantage, translocate the cell body, and, finally, detach through the substratum in the trailing advantage (Lauffenburger and Horwitz, 1996; Ridley et al., 2003). Directed cell migration is normally initiated in response to extracellular cues such as for example chemoattractants, development factors, as well as the extracellular matrix. The establishment and maintenance of polarity during directed migration are ...

Waldenström macroglobulinemia (WM) is a proliferative disorder of IgM-secreting, lymphoplasmacytoid cells that inhabit the lymph nodes and bone marrow. The disease carries a high prevalence of activating mutations in MyD88 (91%) and CXCR4 (28%). Because signaling through these pathways leads to Bcl-xL induction, we examined Bcl-2 family expression in WM patients and cell lines. Unlike other B-lymphocyte-derived malignancies, which become dependent on expression of anti-apoptotic proteins to counter expression of pro-apoptotic proteins, WM samples expressed both pro- and anti-apoptotic Bcl-2 proteins at low levels similar to their normal B-cell and plasma cell counterparts. Three WM cell lines expressed pro-apoptotic Bcl-2 family members Bim or Bax and Bak at low levels, which determined their sensitivity to inducers of intrinsic apoptosis. In two cell lines, miR-155 upregulation, which is common in WM, was responsible for the inhibition of FOXO3a and Bim expression. Both antagonizing miR-155 to ...
The results above reveal that, in contrast to down-regulation of Bcl-2 and Mcl-1 by ER stress in a number of cell types ( 7, 15), these antiapoptotic proteins of the Bcl-2 family are transcriptionally up-regulated by ER stress in human melanoma cell lines. They show that the increase in Mcl-1 plays an essential role in antagonizing the proapoptotic BH3-only proteins PUMA and Noxa, which are also up-regulated by transcriptional mechanisms in melanoma cell lines when subjected to ER stress.. Although up-regulated, Bcl-2 did not seem to be critical for protection of melanoma cells from ER stress-induced apoptosis. This was evidenced by the minimal effect of siRNA inhibition of Bcl-2 on sensitivity of melanoma cells to apoptosis induced by thapsigargin or tunicamycin, and the inability of overexpression of Bcl-2 to rescue melanoma cells with deficient Mcl-1 expression upon ER stress, although it did delay the onset of apoptosis. In contrast, siRNA inhibition of Mcl-1 readily enhanced ER ...

Combination Study of Guadecitabine and Pembrolizumab. - Full Text View - ClinicalTrials.gov
This is a phase I trial of the combination of the hypo-methylating agent guadecitabine and an anti-PD1 antibody (anti- programmed cell death protein 1) pembrolizumab. Patients will receive subcutaneous guadecitabine daily on Days 1-4 of each 21-day cycle. Patients will receive pembrolizumab intravenously once per 21-day cycle: on Day 8 of Cycle 2 and on Day 1 of each cycle from Cycle 3 onwards.. The rational for this design is that this pre-loading with Guadecitabine will sensitise the tumour to Pembrolizumab through the re-expression of genes that enhance tumour recognition, the increase in density of tumour infiltrating T-cells and stimulation of the adaptive immune response.. In Part A (Dose Escalation) the investigators will investigate escalating doses of Guadecitabine in combination with Pembrolizumab. Patients with advanced solid tumours will be recruited in cohorts of 3 to 6 patients to investigate the combination of 200 mg of pembrolizumab, administered as an intravenous injection, with ...
