    Spontaneous and x-ray-triggered crystallization at long range in self-assembling filament networks (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2009-12-19
    Beschreibung: We report here crystallization at long range in networks of like-charge supramolecular peptide filaments mediated by repulsive forces. The crystallization is spontaneous beyond a given concentration of the molecules that form the filaments but can be triggered by x-rays at lower concentrations. The crystalline domains formed by x-ray irradiation, with interfilament separations of up to 320 angstroms, can be stable for hours after the beam is turned off, and ions that screen charges on the filaments suppress ordering. We hypothesize that the stability of crystalline domains emerges from a balance of repulsive tensions linked to native or x-ray-induced charges and the mechanical compressive entrapment of filaments within a network. Similar phenomena may occur naturally in the cytoskeleton of cells and, if induced externally in biological or artificial systems, lead to possible biomedical and lithographic functions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3086396/" 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/PMC3086396/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cui, Honggang -- Pashuck, E Thomas -- Velichko, Yuri S -- Weigand, Steven J -- Cheetham, Andrew G -- Newcomb, Christina J -- Stupp, Samuel I -- 5R01 DE015920/DE/NIDCR NIH HHS/ -- R01 DE015920/DE/NIDCR NIH HHS/ -- R01 DE015920-05/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 29;327(5965):555-9. doi: 10.1126/science.1182340.

    p53 controls radiation-induced gastrointestinal syndrome in mice independent of apoptosis (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2009-12-19
    Beschreibung: Acute exposure to ionizing radiation can cause lethal damage to the gastrointestinal (GI) tract, a condition called the GI syndrome. Whether the target cells affected by radiation to cause the GI syndrome are derived from the epithelium or endothelium and whether the target cells die by apoptosis or other mechanisms are controversial issues. Studying mouse models, we found that selective deletion of the proapoptotic genes Bak1 and Bax from the GI epithelium or from endothelial cells did not protect mice from developing the GI syndrome after sub-total-body gamma irradiation. In contrast, selective deletion of p53 from the GI epithelium, but not from endothelial cells, sensitized irradiated mice to the GI syndrome. Transgenic mice overexpressing p53 in all tissues were protected from the GI syndrome after irradiation. These results suggest that the GI syndrome is caused by the death of GI epithelial cells and that these epithelial cells die by a mechanism that is regulated by p53 but independent of apoptosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2897160/" 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/PMC2897160/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kirsch, David G -- Santiago, Philip M -- di Tomaso, Emmanuelle -- Sullivan, Julie M -- Hou, Wu-Shiun -- Dayton, Talya -- Jeffords, Laura B -- Sodha, Pooja -- Mercer, Kim L -- Cohen, Rhianna -- Takeuchi, Osamu -- Korsmeyer, Stanley J -- Bronson, Roderick T -- Kim, Carla F -- Haigis, Kevin M -- Jain, Rakesh K -- Jacks, Tyler -- K08 CA 114176/CA/NCI NIH HHS/ -- K08 CA114176/CA/NCI NIH HHS/ -- K08 CA114176-05/CA/NCI NIH HHS/ -- P01 CA080124/CA/NCI NIH HHS/ -- P01 CA080124-01A1/CA/NCI NIH HHS/ -- P01 CA80124/CA/NCI NIH HHS/ -- P30 CA014051/CA/NCI NIH HHS/ -- P30 CA014051-38/CA/NCI NIH HHS/ -- P30 DK043351/DK/NIDDK NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- RC1 AI078521/AI/NIAID NIH HHS/ -- RC1 AI078521-01/AI/NIAID NIH HHS/ -- RC1-AI078521/AI/NIAID NIH HHS/ -- U19-AI06775/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jan 29;327(5965):593-6. doi: 10.1126/science.1166202.

    Norbin is an endogenous regulator of metabotropic glutamate receptor 5 signaling (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2009-12-17
    Beschreibung: Metabotropic glutamate receptor 5 (mGluR5) is highly expressed in the mammalian central nervous system (CNS). It is involved in multiple physiological functions and is a target for treatment of various CNS disorders, including schizophrenia. We report that Norbin, a neuron-specific protein, physically interacts with mGluR5 in vivo, increases the cell surface localization of the receptor, and positively regulates mGluR5 signaling. Genetic deletion of Norbin attenuates mGluR5-dependent stable changes in synaptic function measured as long-term depression or long-term potentiation of synaptic transmission in the hippocampus. As with mGluR5 knockout mice or mice treated with mGluR5-selective antagonists, Norbin knockout mice showed a behavioral phenotype associated with a rodent model of schizophrenia, as indexed by alterations both in sensorimotor gating and psychotomimetic-induced locomotor activity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2796550/" 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/PMC2796550/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Hong -- Westin, Linda -- Nong, Yi -- Birnbaum, Shari -- Bendor, Jacob -- Brismar, Hjalmar -- Nestler, Eric -- Aperia, Anita -- Flajolet, Marc -- Greengard, Paul -- DA 10044/DA/NIDA NIH HHS/ -- MH074866/MH/NIMH NIH HHS/ -- MH66172/MH/NIMH NIH HHS/ -- P01 DA010044/DA/NIDA NIH HHS/ -- P01 DA010044-020002/DA/NIDA NIH HHS/ -- P01 DA010044-030002/DA/NIDA NIH HHS/ -- P01 DA010044-04/DA/NIDA NIH HHS/ -- P01 DA010044-040002/DA/NIDA NIH HHS/ -- P01 DA010044-05/DA/NIDA NIH HHS/ -- P01 DA010044-050002/DA/NIDA NIH HHS/ -- P01 DA010044-06/DA/NIDA NIH HHS/ -- P01 DA010044-060002/DA/NIDA NIH HHS/ -- P01 DA010044-07/DA/NIDA NIH HHS/ -- P01 DA010044-070002/DA/NIDA NIH HHS/ -- P01 DA010044-08/DA/NIDA NIH HHS/ -- P01 DA010044-080002/DA/NIDA NIH HHS/ -- P01 DA010044-09/DA/NIDA NIH HHS/ -- P01 DA010044-090002/DA/NIDA NIH HHS/ -- P01 DA010044-10/DA/NIDA NIH HHS/ -- P01 DA010044-100002/DA/NIDA NIH HHS/ -- P01 DA010044-11/DA/NIDA NIH HHS/ -- P01 DA010044-110005/DA/NIDA NIH HHS/ -- P01 DA010044-12/DA/NIDA NIH HHS/ -- P01 DA010044-120005/DA/NIDA NIH HHS/ -- P01 DA010044-129002/DA/NIDA NIH HHS/ -- P01 DA010044-13/DA/NIDA NIH HHS/ -- P01 DA010044-130005/DA/NIDA NIH HHS/ -- P01 DA010044-139002/DA/NIDA NIH HHS/ -- P01 DA010044-14/DA/NIDA NIH HHS/ -- P01 DA010044-140005/DA/NIDA NIH HHS/ -- P01 DA010044-149002/DA/NIDA NIH HHS/ -- P01 DA010044-14S1/DA/NIDA NIH HHS/ -- P01 DA010044-14S10005/DA/NIDA NIH HHS/ -- P01 DA010044-14S19002/DA/NIDA NIH HHS/ -- P50 MH074866/MH/NIMH NIH HHS/ -- P50 MH074866-010001/MH/NIMH NIH HHS/ -- P50 MH074866-020001/MH/NIMH NIH HHS/ -- P50 MH074866-030001/MH/NIMH NIH HHS/ -- P50 MH074866-039001/MH/NIMH NIH HHS/ -- P50 MH074866-040001/MH/NIMH NIH HHS/ -- P50 MH074866-050001/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1554-7. doi: 10.1126/science.1178496.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular and Cellular Neuroscience, Rockefeller University, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20007903" target="_blank"〉PubMed〈/a〉

    MicroRNA-206 delays ALS progression and promotes regeneration of neuromuscular synapses in mice (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2009-12-17
    Beschreibung: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by loss of motor neurons, denervation of target muscles, muscle atrophy, and paralysis. Understanding ALS pathogenesis may require a fuller understanding of the bidirectional signaling between motor neurons and skeletal muscle fibers at neuromuscular synapses. Here, we show that a key regulator of this signaling is miR-206, a skeletal muscle-specific microRNA that is dramatically induced in a mouse model of ALS. Mice that are genetically deficient in miR-206 form normal neuromuscular synapses during development, but deficiency of miR-206 in the ALS mouse model accelerates disease progression. miR-206 is required for efficient regeneration of neuromuscular synapses after acute nerve injury, which probably accounts for its salutary effects in ALS. miR-206 mediates these effects at least in part through histone deacetylase 4 and fibroblast growth factor signaling pathways. Thus, miR-206 slows ALS progression by sensing motor neuron injury and promoting the compensatory regeneration of neuromuscular synapses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2796560/" 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/PMC2796560/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, Andrew H -- Valdez, Gregorio -- Moresi, Viviana -- Qi, Xiaoxia -- McAnally, John -- Elliott, Jeffrey L -- Bassel-Duby, Rhonda -- Sanes, Joshua R -- Olson, Eric N -- 1F32NS061464-01A1/NS/NINDS NIH HHS/ -- R01 HL093039/HL/NHLBI NIH HHS/ -- R01 HL093039-01A1/HL/NHLBI NIH HHS/ -- T32HL007360/HL/NHLBI NIH HHS/ -- U24 CA126608/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1549-54. doi: 10.1126/science.1181046.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, University of Texas Southwestern Medical Center, Dallas, TX 75390, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20007902" target="_blank"〉PubMed〈/a〉

    A spindle assembly checkpoint protein functions in prophase I arrest and prometaphase progression (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2009-12-08
    Beschreibung: Two critical stages of mammalian oocyte regulation are prophase I arrest, which is important for sustaining the oocyte pool, and the progression through meiosis I (MI) to produce fertilizable eggs. We have found that the spindle assembly checkpoint protein BubR1 regulates both stages in mouse oocytes. We show that oocytes depleted of BubR1 cannot sustain prophase I arrest and readily undergo germinal vesicle breakdown, a marker for reentry into MI. BubR1-depleted oocytes then arrest before completing MI, marked by failure of polar body extrusion. Both meiotic defects in BubR1-depleted oocytes are due to reduced activity of the master regulator known as the anaphase-promoting complex (APC), brought about through diminished levels of the APC coactivator Cdh1.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3428834/" 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/PMC3428834/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Homer, Hayden -- Gui, Liming -- Carroll, John -- 082587/Wellcome Trust/United Kingdom -- 082587/Z/07/Z/Wellcome Trust/United Kingdom -- G0400530/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):991-4. doi: 10.1126/science.1175326.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Oocyte and Embryo Research Laboratory, Department of Cell and Developmental Biology, Division of Biosciences and Institute for Women's Health, University College London, London, UK. h.homer@ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965510" target="_blank"〉PubMed〈/a〉

    Structure of an RNA polymerase II-TFIIB complex and the transcription initiation mechanism (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2009-12-08
    Beschreibung: Previous x-ray crystal structures have given insight into the mechanism of transcription and the role of general transcription factors in the initiation of the process. A structure of an RNA polymerase II-general transcription factor TFIIB complex at 4.5 angstrom resolution revealed the amino-terminal region of TFIIB, including a loop termed the "B finger," reaching into the active center of the polymerase where it may interact with both DNA and RNA, but this structure showed little of the carboxyl-terminal region. A new crystal structure of the same complex at 3.8 angstrom resolution obtained under different solution conditions is complementary with the previous one, revealing the carboxyl-terminal region of TFIIB, located above the polymerase active center cleft, but showing none of the B finger. In the new structure, the linker between the amino- and carboxyl-terminal regions can also be seen, snaking down from above the cleft toward the active center. The two structures, taken together with others previously obtained, dispel long-standing mysteries of the transcription initiation process.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2813267/" 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/PMC2813267/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Xin -- Bushnell, David A -- Wang, Dong -- Calero, Guillermo -- Kornberg, Roger D -- AI21144/AI/NIAID NIH HHS/ -- GM049985/GM/NIGMS NIH HHS/ -- K99 GM085136/GM/NIGMS NIH HHS/ -- K99 GM085136-02/GM/NIGMS NIH HHS/ -- R00 GM085136/GM/NIGMS NIH HHS/ -- R01 AI021144/AI/NIAID NIH HHS/ -- R01 AI021144-25/AI/NIAID NIH HHS/ -- R01 GM036659/GM/NIGMS NIH HHS/ -- R01 GM049985/GM/NIGMS NIH HHS/ -- R01 GM049985-16/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):206-9. doi: 10.1126/science.1182015.

    Tetrathiomolybdate inhibits copper trafficking proteins through metal cluster formation (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2009-12-08
    Beschreibung: Tetrathiomolybdate (TM) is an orally active agent for treatment of disorders of copper metabolism. Here we describe how TM inhibits proteins that regulate copper physiology. Crystallographic results reveal that the surprising stability of the drug complex with the metallochaperone Atx1 arises from formation of a sulfur-bridged copper-molybdenum cluster reminiscent of those found in molybdenum and iron sulfur proteins. Spectroscopic studies indicate that this cluster is stable in solution and corresponds to physiological clusters isolated from TM-treated Wilson's disease animal models. Finally, mechanistic studies show that the drug-metallochaperone inhibits metal transfer functions between copper-trafficking proteins. The results are consistent with a model wherein TM can directly and reversibly down-regulate copper delivery to secreted metalloenzymes and suggest that proteins involved in metal regulation might be fruitful drug targets.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3658115/" 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/PMC3658115/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alvarez, Hamsell M -- Xue, Yi -- Robinson, Chandler D -- Canalizo-Hernandez, Monica A -- Marvin, Rebecca G -- Kelly, Rebekah A -- Mondragon, Alfonso -- Penner-Hahn, James E -- O'Halloran, Thomas V -- GM38047/GM/NIGMS NIH HHS/ -- GM38784/GM/NIGMS NIH HHS/ -- GM54222/GM/NIGMS NIH HHS/ -- R01 GM038047/GM/NIGMS NIH HHS/ -- R01 GM038784/GM/NIGMS NIH HHS/ -- R01 GM054111/GM/NIGMS NIH HHS/ -- R37 GM038784/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):331-4. doi: 10.1126/science.1179907.

    Structural basis of immune evasion at the site of CD4 attachment on HIV-1 gp120 (2009)
    American Association for the Advancement of Science (AAAS)
    Details

    Beschreibung: The site on HIV-1 gp120 that binds to the CD4 receptor is vulnerable to antibodies. However, most antibodies that interact with this site cannot neutralize HIV-1. To understand the basis of this resistance, we determined co-crystal structures for two poorly neutralizing, CD4-binding site (CD4BS) antibodies, F105 and b13, in complexes with gp120. Both antibodies exhibited approach angles to gp120 similar to those of CD4 and a rare, broadly neutralizing CD4BS antibody, b12. Slight differences in recognition, however, resulted in substantial differences in F105- and b13-bound conformations relative to b12-bound gp120. Modeling and binding experiments revealed these conformations to be poorly compatible with the viral spike. This incompatibility, the consequence of slight differences in CD4BS recognition, renders HIV-1 resistant to all but the most accurately targeted antibodies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2862588/" 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/PMC2862588/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Lei -- Kwon, Young Do -- Zhou, Tongqing -- Wu, Xueling -- O'Dell, Sijy -- Cavacini, Lisa -- Hessell, Ann J -- Pancera, Marie -- Tang, Min -- Xu, Ling -- Yang, Zhi-Yong -- Zhang, Mei-Yun -- Arthos, James -- Burton, Dennis R -- Dimitrov, Dimiter S -- Nabel, Gary J -- Posner, Marshall R -- Sodroski, Joseph -- Wyatt, Richard -- Mascola, John R -- Kwong, Peter D -- Z99 AI999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1123-7. doi: 10.1126/science.1175868.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vaccine Research Center, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965434" target="_blank"〉PubMed〈/a〉
