    Notes: Acid sludge produced from regeneration of used lubricating oil was chemically treated in order to convert it in to a saleable product. Investigates treatment with different inorganic formulations. Determines and discusses the optimum formulation composition. Characterizes the spectroscopic analysis, thermogravimetric and rheology behaviours, and hydrocarbon type analysis (asphaltene, oil and resin) of the extracted multicomponent resin (MCR-1). Uses the MCR-1 for the preparation of gilsonite varnish. The physico-chemical properties of the latter were determined and compared with those of a standard gilsonite varnish. Concludes that treatment of acid sludge with different salt formulations provides a potentially lowest cost source of gilsonite varnish for news ink and also helps reduce an environmental problem created by re-refining used oil.

    Notes: Measures the intrinsic viscosities, in acetone and tetrahydrofurane (THF) at different temperatures, of a terpolymer of methyl methacrylate, ethyl acrylate and methacrylic acid, prepared by semicontinuous emulsion polymerization (latex). Analyses data with the aid of the equations of Huggins, Kraemer, Martin, Schulz-Blaschke and an equation recently suggested by Rao. Considers relationships between different parameters. By comparing uncleaned samples with samples purified by single precipitation or by dissolution and precipitation from THF, observes the effects of low-molecular weight and water-soluble on the intrinsic viscosities. Discusses solvent powers and effects of degree of purification and temperature on viscosity. Discusses polymer-solvents interactions in terms of the acceptor/donor properties of the solvents. Concludes that purification of functionalized latices can lead to modifications of the original systems, through the elimination of different polymer chains.

    Notes: Applies Fourier transform infrared spectroscopy (FTIR) to the study of lac resin, a complex natural resin of insect origin, and some of its derivatives. Compares the result obtained by this method with those from earlier studies that used classical methods of chemical analysis (the so-called wet methods). Finds that FTIR has several advantages over the classical methods but, as spectroscopic assignments are still only tentative because of the complex nature of the lac resin, the FTIR data requires supplementing by other instrumental techniques such as FT-Raman spectroscopy and solid state nuclear magnetic resonance.

    Notes: Carbamoylethyl starch (CrES) and cyanoethyl starch (CES) were prepared by making use of the concept of the dry process under conditions which were developed to form the bases of environmentally sound (clean) technology. The obtained CrES and CES were saponified using alcoholic NaOH solution. The CrES and CES along with their saponified products were further modified by subjecting them to graft polymerization with Aam/AN mixture. Saponification of the so-obtained grafted substances was also carried out. Presents the findings of these investigations which are explained in terms of structural changes in the starch, the -CN and CONH2 groups, the Aam/AN polymeric graft and the site of attachment of the latter on the modified starch.

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Epoxy resin emulsions are used in water-based coatings for surface protection of concrete and metal. An unfortunate drawback for most emulsions is their poor freeze-thaw stability. Epoxy emulsions are indeed unstable below 0°C, -5°C or -10°C, depending on the type of resin. In this study, other factors capable of influencing the freeze-thaw behaviour were investigated: e.g. solids content, amount and type of emulsifiers, solvents, protective colloids. Discusses methods for testing the quality of thawed emulsions as well as the physics involved in their destabilization. Freeze-thaw performance can be improved by different means but mostly not without sacrificing resistance properties of the coating. Therefore, avoiding temperatures below 0°C is still the best advice.

    Notes: Details the preparation of emulsion copolymerization of styrene (St)-vinylacetate (VAc) with different molar ratio 33:67(A1), 50:50(A2) and 67:33(A3) using redox initiator system (k2S208/NaHS03) and investigates their film forming. Finds that the drying film characterization took on a brittle property which is attributed to the nature of styrene polymers. Explains that molar ratio 67:33 from butyl acrylate (BuA-VAc) and vinyl acetate (B1, B2 and B3) in the presence of pluronic F87 was chosen as the coemulsifier as it gives good transparent and elastic film properties but has a tacky character owing to the nature of butyl acrylate polymer. Shows that styrene-butylacrylate (St-BuA) 67:33 molar ratio(C) has high conversion and a solid content of 51 per cent, and its film forming gives a transparent sheet that dries within 45 minutes. Notes that incorporation of these latices into interior and exterior coatings gives good characterization (hardness, ductility, adhesion and washability of 4,042 cycles) compared with the standard specifications for evaluation of latex paint.

    Notes: Describes a study undertaken to evaluate the efficiency of heat-resistant paint formulations based on Egyptian manganese ore. Highly efficient heat-resistant paint formulations based on Egyptian manganese ore (high and medium grades) and silicon resin were prepared. The heat-resistance efficiency, as well as the physico-mechanical properties of the painted films were evaluated. Promising results were deduced which revealed that manganese ore imparts heat resistance protection for painted substrate up to 450°C. The anticorrosive properties of the mentioned paint formulations were moderate but their efficiency as heat resistant anticorrosive paint was improved by adding 1 per cent of melamine to the paint constituents.

    Notes: The UK Environmental Protection Act imposes very strict controls on paint and other coating systems. These include the reduction and eventual elimination of volatile organic compounds (VOCs); the elimination of offensive odours; and much tighter controls on waste disposal. Ecopaint is a revolutionary new water-based paint with very low levels of organic solvent, greatly reduced odours and can be recycled and reused. Overspray can be reused using ultrafiltration methods, ensuring 100 per cent paint utilization and the elimination of paint waste. This system represents a fundamental advance in industrial painting processes. It provides an entirely new concept for the coating industry and is suitable for a wide range of applications, pointing the way forward in the UK to cost-effective and environmentally-acceptable painting systems.

    Notes: Samples of loomstate cotton fabric were first treated with aqueous potassium permanganate solution at different concentrations in the presence of a non-ionic wetting agent. The samples were then washed and treated using solutions containing methacrylic acid, wetting agent and acid or basic dye along with citric acid of different concentrations at different temperatures for different times. The critical properties of the fabric such as graft yield (expressed as carboxyl content m.eq/100g cellulose), colour strength before and after soaping and percentage loss in colour strength due to soaping were found to depend on the concentrations of KMnO4, citric acid and methacrylic acid as well as duration of the treatment. Based on the results obtained, treating formulations consisting of KMnO4 (0.1g/l), citric acid (0.1g/l), methacrylic acid (50 per cent), dye (1 per cent) and wetting agent (2g/l) was considered appropriate for concurrent grafting and dyeing of the said fabrics provided that the treatment was carried out at 90°C for 60 minutes.

    The role of hot-melt adhesives in sift-proof sealing (1997)

    Notes: High speed cartoning offers a convenient way to pack a wide range of products. Sift-proof sealing is a technique which can provide major savings in energy and raw materials, thus reducing both cost and demands on resources. PVA has been the traditional adhesive used, but hot-melt adhesives have a number of advantages, not least of which is speed. This is becoming increasingly important as packers demand greater production speeds and so hot-melt adhesives are gradually supplanting PVA. Both elements of the process, adhesive and application equipment, will have to be skilfully engineered in order to cope with the added stresses placed on them by these high speeds. An exciting new development of the sift-proof technique has recently been unveiled, whereby a treated paper membrane is bonded to the inside of the carton at each end. Not only does this provide a means of applying a complete "circuit" of hot melt to give a totally air-tight pack but its barrier properties allow the carton to be used for perishable products. Further developments of the sift-proof technique in the future can be expected.

    STATs and gene regulation (1997)

    Details
    Publication Date: 1997-09-12
    Description: STATs (signal transducers and activators of transcription) are a family of latent cytoplasmic proteins that are activated to participate in gene control when cells encounter various extracellular polypeptides. Biochemical and molecular genetic explorations have defined a single tyrosine phosphorylation site and, in a dimeric partner molecule, an Src homology 2 (SH2) phosphotyrosine-binding domain, a DNA interaction domain, and a number of protein-protein interaction domains (with receptors, other transcription factors, the transcription machinery, and perhaps a tyrosine phosphatase). Mouse genetics experiments have defined crucial roles for each known mammalian STAT. The discovery of a STAT in Drosophila, and most recently in Dictyostelium discoideum, implies an ancient evolutionary origin for this dual-function set of proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Darnell, J E Jr -- AI32489/AI/NIAID NIH HHS/ -- AI34420/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1997 Sep 12;277(5332):1630-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Cell Biology, Rockefeller University, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9287210" target="_blank"〉PubMed〈/a〉

    Mass Spawning by Green Algae on Coral Reefs (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-02-21
    Description: Predawn episodes of mass spawning by green algae (up to nine species in five genera on a single morning) intermittently cloud Caribbean waters. Species- and sex-specific bouts of anisogamous gamete release occurred synchronously and predictably on a given morning, with closely related species spawning at different times. Algal sexual reproduction was seasonal, but, unlike the mass-spawning behavior of other sessile marine organisms, showed no lunar or tidal cycling. The discovery of mass-spawning behavior by these algae has important implications for future studies of the reproductive ecology and speciation of a vital, yet poorly understood, component of the coral reef community.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clifton -- New York, N.Y. -- Science. 1997 Feb 21;275(5303):1116-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Smithsonian Tropical Research Institute, Apartado 2072, Balboa, Panama.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9027310" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-01-31
    Description: Saturn's giant moon Titan has a thick (1.5 bar) nitrogen atmosphere, which has a temperature structure that is controlled by the absorption of solar and thermal radiation by methane, hydrogen, and organic aerosols into which methane is irreversibly converted by photolysis. Previous studies of Titan's climate evolution have been done with the assumption that the methane abundance was maintained against photolytic depletion throughout Titan's history, either by continuous supply from the interior or by buffering by a surface or near surface reservoir. Radiative-convective and radiative-saturated equilibrium models of Titan's atmosphere show that methane depletion may have allowed Titan's atmosphere to cool so that nitrogen, its main constituent, condenses onto the surface, collapsing Titan into a Triton-like frozen state with a thin atmosphere.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lorenz, R D -- McKay, C P -- Lunine, J I -- New York, N.Y. -- Science. 1997 Jan 31;275(5300):642-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Planetary Sciences, Lunar and Planetary Laboratory, University of Arizona, Tucson 85721, USA.rlorenz@pl.arizona.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9005844" target="_blank"〉PubMed〈/a〉

    Description: Conversion of methane to higher hydrocarbons by its low-temperature activation without forming undesirable carbon oxides is of great scientific and practical importance. Methane can be highly activated, yielding high rates of conversion to higher hydrocarbons and aromatics (10 to 45 percent) at low temperatures (400° to 600°C), by its reaction over H-galloaluminosilicate ZSM-5 type (MFI) zeolite in the presence of alkenes or higher alkanes. The methane activation results from its hydrogen-transfer reaction with alkenes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Choudhary -- Kinage -- New York, N.Y. -- Science. 1997 Feb 28;275(5304):1286-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Chemical Engineering Division, National Chemical Laboratory, Pune 411 008, India.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9036848" target="_blank"〉PubMed〈/a〉

    Nuclear accumulation of NFAT4 opposed by the JNK signal transduction pathway (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-12-31
    Description: The nuclear factor of activated T cells (NFAT) group of transcription factors is retained in the cytoplasm of quiescent cells. NFAT activation is mediated in part by induced nuclear import. This process requires calcium-dependent dephosphorylation of NFAT caused by the phosphatase calcineurin. The c-Jun amino-terminal kinase (JNK) phosphorylates NFAT4 on two sites. Mutational removal of the JNK phosphorylation sites caused constitutive nuclear localization of NFAT4. In contrast, JNK activation in calcineurin-stimulated cells caused nuclear exclusion of NFAT4. These findings show that the nuclear accumulation of NFAT4 promoted by calcineurin is opposed by the JNK signal transduction pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chow, C W -- Rincon, M -- Cavanagh, J -- Dickens, M -- Davis, R J -- CA58396/CA/NCI NIH HHS/ -- CA65831/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 28;278(5343):1638-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Program in Molecular Medicine, Department of Biochemistry and Molecular Biology, University of Massachusetts Medical School, Worcester, MA 01605, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9374467" target="_blank"〉PubMed〈/a〉

    Publication Date: 1997-03-21
    Description: The "Spanish" influenza pandemic killed at least 20 million people in 1918-1919, making it the worst infectious pandemic in history. Understanding the origins of the 1918 virus and the basis for its exceptional virulence may aid in the prediction of future influenza pandemics. RNA from a victim of the 1918 pandemic was isolated from a formalin-fixed, paraffin-embedded, lung tissue sample. Nine fragments of viral RNA were sequenced from the coding regions of hemagglutinin, neuraminidase, nucleoprotein, matrix protein 1, and matrix protein 2. The sequences are consistent with a novel H1N1 influenza A virus that belongs to the subgroup of strains that infect humans and swine, not the avian subgroup.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taubenberger, J K -- Reid, A H -- Krafft, A E -- Bijwaard, K E -- Fanning, T G -- New York, N.Y. -- Science. 1997 Mar 21;275(5307):1793-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Pathology, Department of Cellular Pathology, Armed Forces Institute of Pathology, Washington DC 20306-6000, USA. taubenbe@email.afip.osd.mil〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9065404" target="_blank"〉PubMed〈/a〉

    Discrete determinants in transfer RNA for editing and aminoacylation (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-05-23
    Description: During translation errors of aminoacylation are corrected in editing reactions which ensure that an amino acid is stably attached to its corresponding transfer RNA (tRNA). Previous studies have not shown whether the tRNA nucleotides needed for effecting translational editing are the same as or distinct from those required for aminoacylation, but several considerations have suggested that they are the same. Here, designed tRNAs that are highly active for aminoacylation but are not active in translational editing are presented. The editing reaction can be controlled by manipulation of nucleotides at the corner of the L-shaped tRNA. In contrast, these manipulations do not affect aminoacylation. These results demonstrate the segregation of nucleotide determinants for the editing and aminoacylation functions of tRNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hale, S P -- Auld, D S -- Schmidt, E -- Schimmel, P -- GM15539/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 May 23;276(5316):1250-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9157882" target="_blank"〉PubMed〈/a〉

    Independent photoreceptive circadian clocks throughout Drosophila (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-12-31
    Description: Transgenic Drosophila that expressed either luciferase or green fluorescent protein driven from the promoter of the clock gene period were used to monitor the circadian clock in explanted head, thorax, and abdominal tissues. The tissues (including sensory bristles in the leg and wing) showed rhythmic bioluminescence, and the rhythms could be reset by light. The photoreceptive properties of the explanted tissues indicate that unidentified photoreceptors are likely to contribute to photic signal transduction to the clock. These results show that autonomous circadian oscillators are present throughout the body, and they suggest that individual cells in Drosophila are capable of supporting their own independent clocks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Plautz, J D -- Kaneko, M -- Hall, J C -- Kay, S A -- MH-51573/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 28;278(5343):1632-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology and National Science Foundation Center for Biological Timing, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9374465" target="_blank"〉PubMed〈/a〉

    Requirement of the DEAD-Box protein ded1p for messenger RNA translation (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-03-07
    Description: The DED1 gene, which encodes a putative RNA helicase, has been implicated in nuclear pre-messenger RNA splicing in the yeast Saccharomyces cerevisiae. It is shown here by genetic and biochemical analysis that translation, rather than splicing, is severely impaired in two newly isolated ded1 conditional mutants. Preliminary evidence suggests that the protein Ded1p may be required for the initiation step of translation, as is the distinct DEAD-box protein, eukaryotic initiation factor 4A (eIF4A). The DED1 gene could be functionally replaced by a mouse homolog, PL10, which suggests that the function of Ded1p in translation is evolutionarily conserved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chuang, R Y -- Weaver, P L -- Liu, Z -- Chang, T H -- GM48752/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Mar 7;275(5305):1468-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular, Cellular, and Developmental Biology Program, Ohio State University, Columbus, OH 43210, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9045610" target="_blank"〉PubMed〈/a〉

    Mating type switching in yeast controlled by asymmetric localization of ASH1 mRNA (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-07-18
    Description: Cell divisions that produce progeny differing in their patterns of gene expression are key to the development of multicellular organisms. In the budding yeast Saccharomyces cerevisiae, mother cells but not daughter cells can switch mating type because they selectively express the HO endonuclease gene. This asymmetry is due to the preferential accumulation of an unstable transcriptional repressor protein, Ash1p, in daughter cell nuclei. Here it is shown that ASH1 messenger RNA (mRNA) preferentially accumulates in daughter cells by a process that is dependent on actin and myosin. A cis-acting element in the 3'-untranslated region of ASH1 mRNA is sufficient to localize a chimeric RNA to daughter cells. These results suggest that localization of mRNA may have been an early property of the eukaryotic lineage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Long, R M -- Singer, R H -- Meng, X -- Gonzalez, I -- Nasmyth, K -- Jansen, R P -- 7 F32 HD08088-02/HD/NICHD NIH HHS/ -- GM54887/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jul 18;277(5324):383-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Structural Biology, Albert Einstein College of Medicine, 1300 Morris Park Avenue, Bronx, NY 10461, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9219698" target="_blank"〉PubMed〈/a〉

    Oncogenic transcription factors in the human acute leukemias (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-11-14
    Description: Chromosomal translocations in the human acute leukemias rearrange the regulatory and coding regions of a variety of transcription factor genes. The resultant protein products can interfere with regulatory cascades that control the growth, differentiation, and survival of normal blood cell precursors. Support for this interpretation comes from the results of gene manipulation studies in mice, as well as the sequence homology of oncogenic transcription factors with proteins known to regulate embryonic development in primitive organisms, including the nematode Caenorhabditis elegans and the fruit fly Drosophila melanogaster. Many of these genetic alterations have important prognostic implications that can guide the selection of therapy. The insights gained from studies of translocation-generated oncogenes and their protein products should hasten the development of highly specific, and hence less toxic, forms of leukemia therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Look, A T -- CA-20180/CA/NCI NIH HHS/ -- CA-21765/CA/NCI NIH HHS/ -- CA-59571/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 7;278(5340):1059-64.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Oncology, St. Jude Children's Research Hospital, Memphis, TN 38105, USA. 38163, USA. thomas.look@stjude.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9353180" target="_blank"〉PubMed〈/a〉

    Publication Date: 1997-11-14
    Description: Genetic testing for cancer susceptibility is already part of the clinical management of families with some of the well-defined (but uncommon) inherited cancer syndromes. In cases where the risks associated with a predisposing mutation are less certain, or where there is no clearly effective intervention to offer those with a positive result, its use is more controversial. Careful evaluation of costs and benefits, and of the efficacy of interventions in those found to be at risk, is essential and is only just beginning. An immediate challenge is to ensure that both health professionals and the public understand clearly the issues involved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ponder, B -- New York, N.Y. -- Science. 1997 Nov 7;278(5340):1050-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Oncology, University of Cambridge, Addenbrooke's Hospital, Box 238, Level 3 Lab Block, Hills Road, Cambridge CB2 2QQ, UK. bajp@mole.bio.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9353178" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1997-11-05
    Description: Reactive and potentially toxic cofactors such as copper ions are imported into eukaryotic cells and incorporated into target proteins by unknown mechanisms. Atx1, a prototypical copper chaperone protein from yeast, has now been shown to act as a soluble cytoplasmic copper(I) receptor that can adopt either a two- or three-coordinate metal center in the active site. Atx1 also associated directly with the Atx1-like cytosolic domains of Ccc2, a vesicular protein defined in genetic studies as a member of the copper-trafficking pathway. The unusual structure and dynamics of Atx1 suggest a copper exchange function for this protein and related domains in the Menkes and Wilson disease proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pufahl, R A -- Singer, C P -- Peariso, K L -- Lin, S J -- Schmidt, P J -- Fahrni, C J -- Culotta, V C -- Penner-Hahn, J E -- O'Halloran, T V -- GM-38047/GM/NIGMS NIH HHS/ -- GM-50016/GM/NIGMS NIH HHS/ -- GM-54111/GM/NIGMS NIH HHS/ -- R01 GM054111/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1997 Oct 31;278(5339):853-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Northwestern University, Evanston, IL 60208, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9346482" target="_blank"〉PubMed〈/a〉

    Mitochondrial and chloroplast phage-type RNA polymerases in Arabidopsis (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-08-08
    Description: In addition to the RNA polymerases (RNAPs) transcribing the nuclear genes, eukaryotic cells also require RNAPs to transcribe the genes of the mitochondrial genome and, in plants, of the chloroplast genome. The plant Arabidopsis thaliana was found to contain two nuclear genes similar to genes encoding the mitochondrial RNAP from yeast and RNAPs of bacteriophages T7, T3, and SP6. The putative transit peptides of the two polymerases were capable of targeting fusion proteins to mitochondria and chloroplasts, respectively, in vitro. The results indicate that the mitochondrial RNAP in plants is a bacteriophage-type enzyme. A gene duplication event may have generated the second RNAP, which along with the plastid-encoded eubacteria-like RNAP could transcribe the chloroplast genome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hedtke, B -- Borner, T -- Weihe, A -- New York, N.Y. -- Science. 1997 Aug 8;277(5327):809-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Humboldt University Berlin, Institute of Biology, Chausseestrasse 117, D-10115 Berlin, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9242608" target="_blank"〉PubMed〈/a〉

    Angiopoietin-2, a natural antagonist for Tie2 that disrupts in vivo angiogenesis (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-07-04
    Description: Angiogenesis is thought to depend on a precise balance of positive and negative regulation. Angiopoietin-1 (Ang1) is an angiogenic factor that signals through the endothelial cell-specific Tie2 receptor tyrosine kinase. Like vascular endothelial growth factor, Ang1 is essential for normal vascular development in the mouse. An Ang1 relative, termed angiopoietin-2 (Ang2), was identified by homology screening and shown to be a naturally occurring antagonist for Ang1 and Tie2. Transgenic overexpression of Ang2 disrupts blood vessel formation in the mouse embryo. In adult mice and humans, Ang2 is expressed only at sites of vascular remodeling. Natural antagonists for vertebrate receptor tyrosine kinases are atypical; thus, the discovery of a negative regulator acting on Tie2 emphasizes the need for exquisite regulation of this angiogenic receptor system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maisonpierre, P C -- Suri, C -- Jones, P F -- Bartunkova, S -- Wiegand, S J -- Radziejewski, C -- Compton, D -- McClain, J -- Aldrich, T H -- Papadopoulos, N -- Daly, T J -- Davis, S -- Sato, T N -- Yancopoulos, G D -- New York, N.Y. -- Science. 1997 Jul 4;277(5322):55-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Regeneron Pharmaceuticals Inc., 777 Old Saw Mill River Road, Tarrytown, NY 10591, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9204896" target="_blank"〉PubMed〈/a〉

    Adenosine: a mediator of the sleep-inducing effects of prolonged wakefulness (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-05-23
    Description: Both subjective and electroencephalographic arousal diminish as a function of the duration of prior wakefulness. Data reported here suggest that the major criteria for a neural sleep factor mediating the somnogenic effects of prolonged wakefulness are satisfied by adenosine, a neuromodulator whose extracellular concentration increases with brain metabolism and which, in vitro, inhibits basal forebrain cholinergic neurons. In vivo microdialysis measurements in freely behaving cats showed that adenosine extracellular concentrations in the basal forebrain cholinergic region increased during spontaneous wakefulness as contrasted with slow wave sleep; exhibited progressive increases during sustained, prolonged wakefulness; and declined slowly during recovery sleep. Furthermore, the sleep-wakefulness profile occurring after prolonged wakefulness was mimicked by increased extracellular adenosine induced by microdialysis perfusion of an adenosine transport inhibitor in the cholinergic basal forebrain but not by perfusion in a control noncholinergic region.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3599777/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3599777/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Porkka-Heiskanen, T -- Strecker, R E -- Thakkar, M -- Bjorkum, A A -- Greene, R W -- McCarley, R W -- R01 MH039683/MH/NIMH NIH HHS/ -- R37 MH39,683/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1997 May 23;276(5316):1265-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, Harvard Medical School, Brockton Veterans Administration Medical Center (VAMC), 116 A, 940 Belmont Street, Brockton, MA 02401, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9157887" target="_blank"〉PubMed〈/a〉

    Crystal structure of the nucleotide exchange factor GrpE bound to the ATPase domain of the molecular chaperone DnaK (1997)

    Publication Date: 1997-04-18
    Description: The crystal structure of the adenine nucleotide exchange factor GrpE in complex with the adenosine triphosphatase (ATPase) domain of Escherichia coli DnaK [heat shock protein 70 (Hsp70)] was determined at 2.8 angstrom resolution. A dimer of GrpE binds asymmetrically to a single molecule of DnaK. The structure of the nucleotide-free ATPase domain in complex with GrpE resembles closely that of the nucleotide-bound mammalian Hsp70 homolog, except for an outward rotation of one of the subdomains of the protein. This conformational change is not consistent with tight nucleotide binding. Two long alpha helices extend away from the GrpE dimer and suggest a role for GrpE in peptide release from DnaK.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harrison, C J -- Hayer-Hartl, M -- Di Liberto, M -- Hartl, F -- Kuriyan, J -- New York, N.Y. -- Science. 1997 Apr 18;276(5311):431-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratories of Molecular Biophysics and Howard Hughes Medical Institute, Rockefeller University, 1230 York Avenue, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9103205" target="_blank"〉PubMed〈/a〉

    Integrating genetic approaches into the discovery of anticancer drugs (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-11-14
    Description: The discovery of anticancer drugs is now driven by the numerous molecular alterations identified in tumor cells over the past decade. To exploit these alterations, it is necessary to understand how they define a molecular context that allows increased sensitivity to particular compounds. Traditional genetic approaches together with the new wealth of genomic information for both human and model organisms open up strategies by which drugs can be profiled for their ability to selectively kill cells in a molecular context that matches those found in tumors. Similarly, it may be possible to identify and validate new targets for drugs that would selectively kill tumor cells with a particular molecular context. This article outlines some of the ways that yeast genetics can be used to streamline anticancer drug discovery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hartwell, L H -- Szankasi, P -- Roberts, C J -- Murray, A W -- Friend, S H -- N01-BC65017/BC/NCI NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 7;278(5340):1064-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Seattle Project, Molecular Pharmacology Department, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9353181" target="_blank"〉PubMed〈/a〉

    Osmotic activation of the HOG MAPK pathway via Ste11p MAPKKK: scaffold role of Pbs2p MAPKK (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-06-13
    Description: Exposure of the yeast Saccharomyces cerevisiae to high extracellular osmolarity induces the Sln1p-Ypd1p-Ssk1p two-component osmosensor to activate a mitogen-activated protein (MAP) kinase cascade composed of the Ssk2p and Ssk22p MAP kinase kinase kinases (MAPKKKs), the Pbs2p MAPKK, and the Hog1p MAPK. A second osmosensor, Sho1p, also activated Pbs2p and Hog1p, but did so through the Ste11p MAPKKK. Although Ste11p also participates in the mating pheromone-responsive MAPK cascade, there was no detectable cross talk between these two pathways. The MAPKK Pbs2p bound to the Sho1p osmosensor, the MAPKKK Ste11p, and the MAPK Hog1p. Thus, Pbs2p may serve as a scaffold protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Posas, F -- Saito, H -- GM50909/GM/NIGMS NIH HHS/ -- GM53415/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 13;276(5319):1702-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Tumor Immunology, Dana-Farber Cancer Institute, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9180081" target="_blank"〉PubMed〈/a〉

    Requirement for macrophage elastase for cigarette smoke-induced emphysema in mice (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-09-26
    Description: To determine which proteinases are responsible for the lung destruction characteristic of pulmonary emphysema, macrophage elastase-deficient (MME-/-) mice were subjected to cigarette smoke. In contrast to wild-type mice, MME-/- mice did not have increased numbers of macrophages in their lungs and did not develop emphysema in response to long-term exposure to cigarette smoke. Smoke-exposed MME-/- mice that received monthly intratracheal instillations of monocyte chemoattractant protein-1 showed accumulation of alveolar macrophages but did not develop air space enlargement. Thus, macrophage elastase is probably sufficient for the development of emphysema that results from chronic inhalation of cigarette smoke.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hautamaki, R D -- Kobayashi, D K -- Senior, R M -- Shapiro, S D -- New York, N.Y. -- Science. 1997 Sep 26;277(5334):2002-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, Washington University School of Medicine at Barnes-Jewish Hospital, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9302297" target="_blank"〉PubMed〈/a〉

    Pain affect encoded in human anterior cingulate but not somatosensory cortex (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-08-15
    Description: Recent evidence demonstrating multiple regions of human cerebral cortex activated by pain has prompted speculation about their individual contributions to this complex experience. To differentiate cortical areas involved in pain affect, hypnotic suggestions were used to alter selectively the unpleasantness of noxious stimuli, without changing the perceived intensity. Positron emission tomography revealed significant changes in pain-evoked activity within anterior cingulate cortex, consistent with the encoding of perceived unpleasantness, whereas primary somatosensory cortex activation was unaltered. These findings provide direct experimental evidence in humans linking frontal-lobe limbic activity with pain affect, as originally suggested by early clinical lesion studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rainville, P -- Duncan, G H -- Price, D D -- Carrier, B -- Bushnell, M C -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):968-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉D-epartement de Psychologie and Centre de Recherche en Sciences Neurologiques, Universite de Montreal, Montreal, Quebec, Canada H3C 3J7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252330" target="_blank"〉PubMed〈/a〉

    Control of vertebrate left-right asymmetry by a snail-related zinc finger gene (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-02-28
    Description: A gene encoding a zinc finger protein of the Snail family, cSnR, is expressed in the right-hand lateral mesoderm during normal chick development. Antisense disruption of cSnR function during the hours immediately preceding heart formation randomized the normally reliable direction of heart looping and subsequent embryo torsion. Implanted ectopic sources of intercellular signal proteins that are involved in establishing normal left-right information randomized the handedness of heart development and also altered the asymmetry of cSnR expression. cSnR thus appears to act downstream of these signals, or perhaps in parallel with the latest expressed of them, the Nodal protein, in controlling the anatomical asymmetry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Isaac, A -- Sargent, M G -- Cooke, J -- New York, N.Y. -- Science. 1997 Feb 28;275(5304):1301-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute for Medical Research, Mill Hill, London NW7 1AA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9036854" target="_blank"〉PubMed〈/a〉

    Description: The healing of an adult skin wound is a complex process requiring the collaborative efforts of many different tissues and cell lineages. The behavior of each of the contributing cell types during the phases of proliferation, migration, matrix synthesis, and contraction, as well as the growth factor and matrix signals present at a wound site, are now roughly understood. Details of how these signals control wound cell activities are beginning to emerge, and studies of healing in embryos have begun to show how the normal adult repair process might be readjusted to make it less like patching up and more like regeneration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, P -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1997 Apr 4;276(5309):75-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Developmental Biology, University College London, Gower Street, London WC1E 6BT, UK. paul.martin@ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9082989" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-11-21
    Description: Many neuropeptides and peptide hormones require amidation at the carboxyl terminus for activity. Peptidylglycine alpha-amidating monooxygenase (PAM) catalyzes the amidation of these diverse physiological regulators. The amino-terminal domain of the bifunctional PAM protein is a peptidylglycine alpha-hydroxylating monooxygenase (PHM) with two coppers that cycle through cupric and cuprous oxidation states. The anomalous signal of the endogenous coppers was used to determine the structure of the catalytic core of oxidized rat PHM with and without bound peptide substrate. These structures strongly suggest that the PHM reaction proceeds via activation of substrate by a copper-bound oxygen species. The mechanistic and structural insight gained from the PHM structures can be directly extended to dopamine beta-monooxygenase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prigge, S T -- Kolhekar, A S -- Eipper, B A -- Mains, R E -- Amzel, L M -- DK32949/DK/NIDDK NIH HHS/ -- GM44692/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Nov 14;278(5341):1300-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biophysics and Biophysical Chemistry, Johns Hopkins School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9360928" target="_blank"〉PubMed〈/a〉

    Rescue of a Drosophila NF1 mutant phenotype by protein kinase A (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-05-02
    Description: The neurofibromatosis type 1 (NF1) tumor suppressor protein is thought to restrict cell proliferation by functioning as a Ras-specific guanosine triphosphatase-activating protein. However, Drosophila homozygous for null mutations of an NF1 homolog showed no obvious signs of perturbed Ras1-mediated signaling. Loss of NF1 resulted in a reduction in size of larvae, pupae, and adults. This size defect was not modified by manipulating Ras1 signaling but was restored by expression of activated adenosine 3', 5'-monophosphate-dependent protein kinase (PKA). Thus, NF1 and PKA appear to interact in a pathway that controls the overall growth of Drosophila.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉The, I -- Hannigan, G E -- Cowley, G S -- Reginald, S -- Zhong, Y -- Gusella, J F -- Hariharan, I K -- Bernards, A -- NS22229/NS/NINDS NIH HHS/ -- NS34779/NS/NINDS NIH HHS/ -- NS36084/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1997 May 2;276(5313):791-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts General Hospital Cancer Center and Harvard Medical School Building 149, 13th Street, Charlestown, MA 02129, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9115203" target="_blank"〉PubMed〈/a〉

    The Seismic 8degrees Discontinuity and Partial Melting in Continental Mantle (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-03-14
    Description: Strong, scattered reflections beyond 8 degrees (8degrees) offset are characteristic features of all high-resolution seismic sections from the continents. The reflections identify a low-velocity zone below approximately 100 kilometers depth beneath generally stratified mantle. This zone may be caused by partial melting, globally initiated at equal depth in the continental mantle. Solid state is again attained at the Lehmann discontinuity in cold, stable areas, whereas the zone extends to near the 400-kilometer discontinuity in hot, tectonically active areas. Thus, the depth to the Lehmann discontinuity may be an indicator of the thermal state of the continental mantle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thybo -- Perchuc -- New York, N.Y. -- Science. 1997 Mar 14;275(5306):1626-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉H.

    Description: A selection strategy was devised to identify bacterial genes preferentially expressed when a bacterium associates with its host cell. Fourteen Salmonella typhimurium genes, which were under the control of at least four independent regulatory circuits, were identified to be selectively induced in host macrophages. Four genes encode virulence factors, including a component of a type III secretory apparatus. This selection methodology should be generally applicable to the identification of genes from pathogenic organisms that are induced upon association with host cells or tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Valdivia, R H -- Falkow, S -- AI26195/AI/NIAID NIH HHS/ -- DK38707/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1997 Sep 26;277(5334):2007-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Stanford University School of Medicine, Stanford, CA 94305, USA. valdivia@cmgm.stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9302299" target="_blank"〉PubMed〈/a〉

    Precursor-directed biosynthesis of erythromycin analogs by an engineered polyketide synthase (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-07-18
    Description: A genetic block was introduced in the first condensation step of the polyketide biosynthetic pathway that leads to the formation of 6-deoxyerythronolide B (6-dEB), the macrocyclic precursor of erythromycin. Exogenous addition of designed synthetic molecules to small-scale cultures of this null mutant resulted in highly selective multimilligram production of unnatural polyketides, including aromatic and ring-expanded variants of 6-dEB. Unexpected incorporation patterns were observed, illustrating the catalytic versatility of modular polyketide synthases. Further processing of some of these scaffolds by postpolyketide enzymes of the erythromycin pathway resulted in the generation of novel antibacterials with in vitro potency comparable to that of their natural counterparts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacobsen, J R -- Hutchinson, C R -- Cane, D E -- Khosla, C -- CA66736/CA/NCI NIH HHS/ -- GM22172/GM/NIGMS NIH HHS/ -- GM31925/GM/NIGMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1997 Jul 18;277(5324):367-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemical Engineering, Stanford University, Stanford, CA 94305-5025, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9219693" target="_blank"〉PubMed〈/a〉

    Regulation of replicon size in Xenopus egg extracts (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-02-14
    Description: Once a specific number of cells have been produced in the early Xenopus laevis embryo, replicon size during the S phase of the cell cycle increases. Here, it is reported that similar increase in replicon size occurred when the concentration of nuclei in replication-competent Xenopus egg extracts exceeded a critical threshold. In this system, the origin recognition complex (ORC) did not become stoichiometrically limiting for initiation, and similar amounts of this complex bound to chromatin regardless of replicon size. These data suggest that in early development, an unidentified factor controls how many preformed ORC-DNA complexes initiate DNA replication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walter, J -- Newport, J W -- 1F32FM17980-01/PHS HHS/ -- R01FM44656/PHS HHS/ -- New York, N.Y. -- Science. 1997 Feb 14;275(5302):993-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of California, San Diego, La Jolla, CA 92093-0347, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9020085" target="_blank"〉PubMed〈/a〉

    Inhibition of Ran guanosine triphosphatase-dependent nuclear transport by the matrix protein of vesicular stomatitis virus (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-06-20
    Description: Transport of macromolecules into and out of nuclei, essential steps in gene expression, are potential points of control. The matrix protein (M protein) of vesicular stomatitis virus (VSV) was shown to block transport of RNAs and proteins between the nucleus and cytoplasm of Xenopus laevis oocytes. The pattern of inhibition indicated that M protein interfered with transport that is dependent on the ras-like nuclear guanosine triphosphatase (GTPase) Ran-TC4 and its associated factors. This inhibition of nuclear transport by M protein explains several observations about the effects of VSV infection on host cell gene expression and suggests that RNA export is closely coupled to protein import.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Her, L S -- Lund, E -- Dahlberg, J E -- GM30220/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 20;276(5320):1845-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biomolecular Chemistry, University of Wisconsin-Madison, 1300 University Avenue, Madison, WI 53706, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9188527" target="_blank"〉PubMed〈/a〉

    A mouse model with features of familial combined hyperlipidemia (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-01-17
    Description: Familial combined hyperlipidemia (FCHL) is a common inherited lipid disorder, affecting 1 to 2 percent of the population in Westernized societies. Individuals with FCHL have large quantities of very low density lipoprotein (VLDL) and low density lipoprotein (LDL) and develop premature coronary heart disease. A mouse model displaying some of the features of FCHL was created by crossing mice carrying the human apolipoprotein C-III (APOC3) transgene with mice deficient in the LDL receptor. A synergistic interaction between the apolipoprotein C-III and the LDL receptor defects produced large quantities of VLDL and LDL and enhanced the development of atherosclerosis. This mouse model may provide clues to the origin of human FCHL.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masucci-Magoulas, L -- Goldberg, I J -- Bisgaier, C L -- Serajuddin, H -- Francone, O L -- Breslow, J L -- Tall, A R -- HL 21006/HL/NHLBI NIH HHS/ -- HL 54591/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1997 Jan 17;275(5298):391-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Columbia University, 630 West 168 Street, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8994037" target="_blank"〉PubMed〈/a〉

    Formation of actin stress fibers and focal adhesions enhanced by Rho-kinase (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-02-28
    Description: The small guanosine triphosphatase (GTPase) Rho is implicated in the formation of stress fibers and focal adhesions in fibroblasts stimulated by extracellular signals such as lysophosphatidic acid (LPA). Rho-kinase is activated by Rho and may mediate some biological effects of Rho. Microinjection of the catalytic domain of Rho-kinase into serum-starved Swiss 3T3 cells induced the formation of stress fibers and focal adhesions, whereas microinjection of the inactive catalytic domain, the Rho-binding domain, or the pleckstrin-homology domain inhibited the LPA-induced formation of stress fibers and focal adhesions. Thus, Rho-kinase appears to mediate signals from Rho and to induce the formation of stress fibers and focal adhesions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amano, M -- Chihara, K -- Kimura, K -- Fukata, Y -- Nakamura, N -- Matsuura, Y -- Kaibuchi, K -- New York, N.Y. -- Science. 1997 Feb 28;275(5304):1308-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Signal Transduction, Nara Institute of Science and Technology, Ikoma 630-01, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9036856" target="_blank"〉PubMed〈/a〉

    Hypermethylated SUPERMAN epigenetic alleles in arabidopsis (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-08-22
    Description: Mutations in the SUPERMAN gene affect flower development in Arabidopsis. Seven heritable but unstable sup epi-alleles (the clark kent alleles) are associated with nearly identical patterns of excess cytosine methylation within the SUP gene and a decreased level of SUP RNA. Revertants of these alleles are largely demethylated at the SUP locus and have restored levels of SUP RNA. A transgenic Arabidopsis line carrying an antisense methyltransferase gene, which shows an overall decrease in genomic cytosine methylation, also contains a hypermethylated sup allele. Thus, disruption of methylation systems may yield more complex outcomes than expected and can result in methylation defects at known genes. The clark kent alleles differ from the antisense line because they do not show a general decrease in genomic methylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacobsen, S E -- Meyerowitz, E M -- New York, N.Y. -- Science. 1997 Aug 22;277(5329):1100-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology 156-29, California Institute of Technology, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9262479" target="_blank"〉PubMed〈/a〉

    Functional specificity among Hsp70 molecular chaperones (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-01-17
    Description: Molecular chaperones of the 70-kilodalton heat shock protein (Hsp70) class bind to partially unfolded polypeptide substrates and participate in a wide variety of cellular processes. Differences in peptide-binding specificity among Hsp70s have led to the hypothesis that peptide binding determines specific Hsp70 functions. Protein domains were identified that were required for two separate functions of a yeast Hsp70 family. The peptide-binding domain was not required for either of these specific Hsp70 functions, which suggests that peptide-binding specificity plays little or no role in determining Hsp70 functions in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉James, P -- Pfund, C -- Craig, E A -- New York, N.Y. -- Science. 1997 Jan 17;275(5298):387-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biomolecular Chemistry, University of Wisconsin, Madison, WI 53706, USA. ecraig@facstaff.wisc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8994035" target="_blank"〉PubMed〈/a〉

    Dictyostelium development in the absence of cAMP (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-07-11
    Description: Adenosine 3',5'-monophosphate (cAMP) and cAMP-dependent protein kinase (PKA) are regulators of development in many organisms. Dictyostelium uses cAMP as an extracellular chemoattractant and as an intracellular signal for differentiation. Cells that are mutant in adenylyl cyclase do not develop. Moderate expression of the catalytic subunit of PKA in adenylyl cyclase-null cells led to near-normal development without detectable accumulation of cAMP. These results suggest that all intracellular cAMP signaling is effected through PKA and that signals other than extracellular cAMP coordinate morphogenesis in Dictyostelium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, B -- Kuspa, A -- R01 GM052359/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jul 11;277(5323):251-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Verna and Marrs McLean Department of Biochemistry, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9211856" target="_blank"〉PubMed〈/a〉

    Chemical selection for catalysis in combinatorial antibody libraries (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-02-14
    Description: For the past decade the immune system has been exploited as a rich source of de novo catalysts. Catalytic antibodies have been shown to have chemoselectivity, enantioselectivity, large rate accelerations, and even an ability to reroute chemical reactions. In many instances catalysts have been made for reactions for which there are no known natural or man-made enzymes. Yet, the full power of this combinatorial system can only be exploited if there was a system that allows for the direct selection of a particular function. A method that allows for the direct chemical selection for catalysis from antibody libraries was so devised, whereby the positive aspects of hybridoma technology were preserved and re-formatted in the filamentous phage system to allow direct selection of catalysis. This methodology is based on a purely chemical selection process, making it more general than biologically based selection systems because it is not limited to reaction products that perturb cellular machinery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janda, K D -- Lo, L C -- Lo, C H -- Sim, M M -- Wang, R -- Wong, C H -- Lerner, R A -- GM-43858/GM/NIGMS NIH HHS/ -- GM-44154/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Feb 14;275(5302):945-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Scripps Research Institute, Department of Chemistry, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9020070" target="_blank"〉PubMed〈/a〉

    Description: Ferroelectric field effect devices offer the possibility of nonvolatile active memory elements. Doped rare-earth manganates, which are usually associated with colossal magnetoresistive properties, have been used as the semiconductor channel material of a prototypical epitaxial field effect device. The carrier concentration of the semiconductor channel can be "tuned" by varying the manganate stochiometry. A device with La0.7Ca0.3MnO3 as the semiconductor and PbZr0.2Ti0.8O3 as the ferroelectric gate exhibited a modulation in channel conductance of at least a factor of 3 and a retention loss of 3 percent after 45 minutes without power.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mathews -- Ramesh -- Venkatesan -- Benedetto -- New York, N.Y. -- Science. 1997 Apr 11;276(5310):238-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉S.

    American Association for the Advancement of Science (AAAS)

    Publication Date: 1997-08-15
    Description: Posttranslational protein translocation across the endoplasmic reticulum membrane of yeast requires a seven-component transmembrane complex (the Sec complex) in collaboration with the lumenal Kar2 protein (Kar2p). A translocation substrate was initially bound to the cytosolic face of the purified Sec complex in a signal-sequence-dependent but Kar2p- and nucleotide-independent manner. In a subsequent reaction, in which Kar2p interacted with the lumenal face of the Sec complex and hydrolyzed adenosine triphosphate, the substrate moved through a channel formed by the Sec complex and was released at the lumenal end. Movement through the channel occurred in detergent solution in the absence of a lipid bilayer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matlack, K E -- Plath, K -- Misselwitz, B -- Rapoport, T A -- GM54238-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Aug 15;277(5328):938-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, 240 Longwood Avenue, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9252322" target="_blank"〉PubMed〈/a〉

    Ndj1p, a meiotic telomere protein required for normal chromosome synapsis and segregation in yeast (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-05-23
    Description: The Saccharomyces cerevisiae gene NDJ1 (nondisjunction) encodes a protein that accumulates at telomeres during meiotic prophase. Deletion of NDJ1 (ndj1Delta) caused nondisjunction, impaired distributive segregation of linear chromosomes, and disordered the distribution of telomeric Rap1p, but it did not affect distributive segregation of circular plasmids. Induction of meiotic recombination and the extent of crossing-over were largely normal in ndj1Delta cells, but formation of axial elements and synapsis were delayed. Thus, Ndj1p may stabilize homologous DNA interactions at telomeres, and possibly at other sites, and it is required for a telomere activity in distributive segregation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Conrad, M N -- Dominguez, A M -- Dresser, M E -- GM45250/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 May 23;276(5316):1252-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Molecular and Cell Biology, Oklahoma Medical Research Foundation, 825 Northeast 13th Street, Oklahoma City, OK 73104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9157883" target="_blank"〉PubMed〈/a〉

    Description: Neuroendocrine hormones of the hypothalamus-pituitary-thyroid axis can exert positive or negative immunoregulatory effects on intestinal lymphocytes. Small intestine epithelial cells were found to express receptors for thyrotropin-releasing hormone (TRH) and to be a primary source of intestine-derived thyroid-stimulating hormone (TSH). The gene for the TSH receptor (TSH-R) was expressed in intestinal T cells but not in epithelial cells, which suggested a hormone-mediated link between lymphoid and nonhematopoietic components of the intestine. Because mice with congenitally mutant TSH-R (hyt/hyt mice) have a selectively impaired intestinal T cell repertoire, TSH may be a key immunoregulatory mediator in the intestine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, J -- Whetsell, M -- Klein, J R -- DK35566/DK/NIDDK NIH HHS/ -- R01 DK035566/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1997 Mar 28;275(5308):1937-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Science and Mervin Bovaird Center for Studies in Molecular Biology and Biotechnology, University of Tulsa, Tulsa, OK 74104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9072972" target="_blank"〉PubMed〈/a〉
