    Mutations in a human ROBO gene disrupt hindbrain axon pathway crossing and morphogenesis (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-24
    Description: The mechanisms controlling axon guidance are of fundamental importance in understanding brain development. Growing corticospinal and somatosensory axons cross the midline in the medulla to reach their targets and thus form the basis of contralateral motor control and sensory input. The motor and sensory projections appeared uncrossed in patients with horizontal gaze palsy with progressive scoliosis (HGPPS). In patients affected with HGPPS, we identified mutations in the ROBO3 gene, which shares homology with roundabout genes important in axon guidance in developing Drosophila, zebrafish, and mouse. Like its murine homolog Rig1/Robo3, but unlike other Robo proteins, ROBO3 is required for hindbrain axon midline crossing.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1618874/" 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/PMC1618874/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jen, Joanna C -- Chan, Wai-Man -- Bosley, Thomas M -- Wan, Jijun -- Carr, Janai R -- Rub, Udo -- Shattuck, David -- Salamon, Georges -- Kudo, Lili C -- Ou, Jing -- Lin, Doris D M -- Salih, Mustafa A M -- Kansu, Tulay -- Al Dhalaan, Hesham -- Al Zayed, Zayed -- MacDonald, David B -- Stigsby, Bent -- Plaitakis, Andreas -- Dretakis, Emmanuel K -- Gottlob, Irene -- Pieh, Christina -- Traboulsi, Elias I -- Wang, Qing -- Wang, Lejin -- Andrews, Caroline -- Yamada, Koki -- Demer, Joseph L -- Karim, Shaheen -- Alger, Jeffry R -- Geschwind, Daniel H -- Deller, Thomas -- Sicotte, Nancy L -- Nelson, Stanley F -- Baloh, Robert W -- Engle, Elizabeth C -- DC00162/DC/NIDCD NIH HHS/ -- DC05524/DC/NIDCD NIH HHS/ -- EY12498/EY/NEI NIH HHS/ -- EY13583/EY/NEI NIH HHS/ -- EY15298/EY/NEI NIH HHS/ -- EY15311/EY/NEI NIH HHS/ -- MH60233/MH/NIMH NIH HHS/ -- P30 HD 18655/HD/NICHD NIH HHS/ -- R01 EY008313/EY/NEI NIH HHS/ -- R01 EY008313-14/EY/NEI NIH HHS/ -- R01 HL066251/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2004 Jun 4;304(5676):1509-13.

    Oscillations in NF-kappaB signaling control the dynamics of gene expression (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-10-23
    Description: Signaling by the transcription factor nuclear factor kappa B (NF-kappaB) involves its release from inhibitor kappa B (IkappaB) in the cytosol, followed by translocation into the nucleus. NF-kappaB regulation of IkappaBalpha transcription represents a delayed negative feedback loop that drives oscillations in NF-kappaB translocation. Single-cell time-lapse imaging and computational modeling of NF-kappaB (RelA) localization showed asynchronous oscillations following cell stimulation that decreased in frequency with increased IkappaBalpha transcription. Transcription of target genes depended on oscillation persistence, involving cycles of RelA phosphorylation and dephosphorylation. The functional consequences of NF-kappaB signaling may thus depend on number, period, and amplitude of oscillations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nelson, D E -- Ihekwaba, A E C -- Elliott, M -- Johnson, J R -- Gibney, C A -- Foreman, B E -- Nelson, G -- See, V -- Horton, C A -- Spiller, D G -- Edwards, S W -- McDowell, H P -- Unitt, J F -- Sullivan, E -- Grimley, R -- Benson, N -- Broomhead, D -- Kell, D B -- White, M R H -- New York, N.Y. -- Science. 2004 Oct 22;306(5696):704-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Cell Imaging, School of Biological Sciences, Bioscience Research Building, Crown Street, Liverpool, L69 7ZB, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15499023" target="_blank"〉PubMed〈/a〉

    The structure and receptor binding properties of the 1918 influenza hemagglutinin (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-07
    Description: The 1918 influenza pandemic resulted in about 20 million deaths. This enormous impact, coupled with renewed interest in emerging infections, makes characterization of the virus involved a priority. Receptor binding, the initial event in virus infection, is a major determinant of virus transmissibility that, for influenza viruses, is mediated by the hemagglutinin (HA) membrane glycoprotein. We have determined the crystal structures of the HA from the 1918 virus and two closely related HAs in complex with receptor analogs. They explain how the 1918 HA, while retaining receptor binding site amino acids characteristic of an avian precursor HA, is able to bind human receptors and how, as a consequence, the virus was able to spread in the human population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gamblin, S J -- Haire, L F -- Russell, R J -- Stevens, D J -- Xiao, B -- Ha, Y -- Vasisht, N -- Steinhauer, D A -- Daniels, R S -- Elliot, A -- Wiley, D C -- Skehel, J J -- AI-13654/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2004 Mar 19;303(5665):1838-42.

    T cell activation by lipopeptide antigens (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-01-24
    Description: Unlike major histocompatibility proteins, which bind peptides, CD1 proteins display lipid antigens to T cells. Here, we report that CD1a presents a family of previously unknown lipopeptides from Mycobacterium tuberculosis, named didehydroxymycobactins because of their structural relation to mycobactin siderophores. T cell activation was mediated by the alphabeta T cell receptors and was specific for structure of the acyl and peptidic components of these antigens. These studies identify a means of intracellular pathogen detection and identify lipopeptides as a biochemical class of antigens for T cells, which, like conventional peptides, have a potential for marked structural diversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moody, D Branch -- Young, David C -- Cheng, Tan-Yun -- Rosat, Jean-Pierre -- Roura-Mir, Carme -- O'Connor, Peter B -- Zajonc, Dirk M -- Walz, Andrew -- Miller, Marvin J -- Levery, Steven B -- Wilson, Ian A -- Costello, Catherine E -- Brenner, Michael B -- AI30988/AI/NIAID NIH HHS/ -- AI50216/AI/NIAID NIH HHS/ -- AR48632/AR/NIAMS NIH HHS/ -- CA58896/CA/NCI NIH HHS/ -- GM25845/GM/NIGMS NIH HHS/ -- GM62116/GM/NIGMS NIH HHS/ -- P20 RR16459/RR/NCRR NIH HHS/ -- P41-RR10888/RR/NCRR NIH HHS/ -- S10-RR10493/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2004 Jan 23;303(5657):527-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Rheumatology, Immunology and Allergy, Brigham and Women's Hospital and Harvard Medical School, Smith Building Room 514, 1 Jimmy Fund Way, Boston, MA 02115, USA. bmoody@rics.bwh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14739458" target="_blank"〉PubMed〈/a〉

    Hereditary early-onset Parkinson's disease caused by mutations in PINK1 (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-17
    Description: Parkinson's disease (PD) is a neurodegenerative disorder characterized by degeneration of dopaminergic neurons in the substantia nigra. We previously mapped a locus for a rare familial form of PD to chromosome 1p36 (PARK6). Here we show that mutations in PINK1 (PTEN-induced kinase 1) are associated with PARK6. We have identified two homozygous mutations affecting the PINK1 kinase domain in three consanguineous PARK6 families: a truncating nonsense mutation and a missense mutation at a highly conserved amino acid. Cell culture studies suggest that PINK1 is mitochondrially located and may exert a protective effect on the cell that is abrogated by the mutations, resulting in increased susceptibility to cellular stress. These data provide a direct molecular link between mitochondria and the pathogenesis of PD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Valente, Enza Maria -- Abou-Sleiman, Patrick M -- Caputo, Viviana -- Muqit, Miratul M K -- Harvey, Kirsten -- Gispert, Suzana -- Ali, Zeeshan -- Del Turco, Domenico -- Bentivoglio, Anna Rita -- Healy, Daniel G -- Albanese, Alberto -- Nussbaum, Robert -- Gonzalez-Maldonado, Rafael -- Deller, Thomas -- Salvi, Sergio -- Cortelli, Pietro -- Gilks, William P -- Latchman, David S -- Harvey, Robert J -- Dallapiccola, Bruno -- Auburger, Georg -- Wood, Nicholas W -- G-4029/Parkinson's UK/United Kingdom -- GGP02089/Telethon/Italy -- New York, N.Y. -- Science. 2004 May 21;304(5674):1158-60.

    Semaphorin 3E and plexin-D1 control vascular pattern independently of neuropilins (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-11-20
    Description: The development of a patterned vasculature is essential for normal organogenesis. We found that signaling by semaphorin 3E (Sema3E) and its receptor plexin-D1 controls endothelial cell positioning and the patterning of the developing vasculature in the mouse. Sema3E is highly expressed in developing somites, where it acts as a repulsive cue for plexin-D1-expressing endothelial cells of adjacent intersomitic vessels. Sema3E-plexin-D1 signaling did not require neuropilins, which were previously presumed to be obligate Sema3 coreceptors. Moreover, genetic ablation of Sema3E or plexin-D1 but not neuropilin-mediated Sema3 signaling disrupted vascular patterning. These findings reveal an unexpected semaphorin signaling pathway and define a mechanism for controlling vascular patterning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gu, Chenghua -- Yoshida, Yutaka -- Livet, Jean -- Reimert, Dorothy V -- Mann, Fanny -- Merte, Janna -- Henderson, Christopher E -- Jessell, Thomas M -- Kolodkin, Alex L -- Ginty, David D -- CA23767-24/CA/NCI NIH HHS/ -- MH59199-06/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2005 Jan 14;307(5707):265-8.

    Structural basis of transcription: an RNA polymerase II-TFIIB cocrystal at 4.5 Angstroms (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-14
    Description: The structure of the general transcription factor IIB (TFIIB) in a complex with RNA polymerase II reveals three features crucial for transcription initiation: an N-terminal zinc ribbon domain of TFIIB that contacts the "dock" domain of the polymerase, near the path of RNA exit from a transcribing enzyme; a "finger" domain of TFIIB that is inserted into the polymerase active center; and a C-terminal domain, whose interaction with both the polymerase and with a TATA box-binding protein (TBP)-promoter DNA complex orients the DNA for unwinding and transcription. TFIIB stabilizes an early initiation complex, containing an incomplete RNA-DNA hybrid region. It may interact with the template strand, which sets the location of the transcription start site, and may interfere with RNA exit, which leads to abortive initiation or promoter escape. The trajectory of promoter DNA determined by the C-terminal domain of TFIIB traverses sites of interaction with TFIIE, TFIIF, and TFIIH, serving to define their roles in the transcription initiation process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bushnell, David A -- Westover, Kenneth D -- Davis, Ralph E -- Kornberg, Roger D -- AI21144/AI/NIAID NIH HHS/ -- GM49985/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 13;303(5660):983-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Biology, Stanford University School of Medicine, Stanford, CA 94305-5126, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14963322" target="_blank"〉PubMed〈/a〉

    Mutational analysis of the tyrosine phosphatome in colorectal cancers (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-05-25
    Description: Tyrosine phosphorylation, regulated by protein tyrosine phosphatases (PTPs) and kinases (PTKs), is important in signaling pathways underlying tumorigenesis. A mutational analysis of the tyrosine phosphatase gene superfamily in human cancers identified 83 somatic mutations in six PTPs (PTPRF, PTPRG, PTPRT, PTPN3, PTPN13, PTPN14), affecting 26% of colorectal cancers and a smaller fraction of lung, breast, and gastric cancers. Fifteen mutations were nonsense, frameshift, or splice-site alterations predicted to result in truncated proteins lacking phosphatase activity. Five missense mutations in the most commonly altered PTP (PTPRT) were biochemically examined and found to reduce phosphatase activity. Expression of wild-type but not a mutant PTPRT in human cancer cells inhibited cell growth. These observations suggest that the mutated tyrosine phosphatases are tumor suppressor genes, regulating cellular pathways that may be amenable to therapeutic intervention.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Zhenghe -- Shen, Dong -- Parsons, D Williams -- Bardelli, Alberto -- Sager, Jason -- Szabo, Steve -- Ptak, Janine -- Silliman, Natalie -- Peters, Brock A -- van der Heijden, Michiel S -- Parmigiani, Giovanni -- Yan, Hai -- Wang, Tian-Li -- Riggins, Greg -- Powell, Steven M -- Willson, James K V -- Markowitz, Sanford -- Kinzler, Kenneth W -- Vogelstein, Bert -- Velculescu, Victor E -- CA 43460/CA/NCI NIH HHS/ -- CA 57345/CA/NCI NIH HHS/ -- CA 62924/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2004 May 21;304(5674):1164-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sidney Kimmel Comprehensive Cancer Center, Howard Hughes Medical Institute, Johns Hopkins University Medical Institutions, Baltimore, MD 21231, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15155950" target="_blank"〉PubMed〈/a〉

    ABAD directly links Abeta to mitochondrial toxicity in Alzheimer's disease (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-17
    Description: Mitochondrial dysfunction is a hallmark of beta-amyloid (Abeta)-induced neuronal toxicity in Alzheimer's disease (AD). Here, we demonstrate that Abeta-binding alcohol dehydrogenase (ABAD) is a direct molecular link from Abeta to mitochondrial toxicity. Abeta interacts with ABAD in the mitochondria of AD patients and transgenic mice. The crystal structure of Abeta-bound ABAD shows substantial deformation of the active site that prevents nicotinamide adenine dinucleotide (NAD) binding. An ABAD peptide specifically inhibits ABAD-Abeta interaction and suppresses Abeta-induced apoptosis and free-radical generation in neurons. Transgenic mice overexpressing ABAD in an Abeta-rich environment manifest exaggerated neuronal oxidative stress and impaired memory. These data suggest that the ABAD-Abeta interaction may be a therapeutic target in AD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lustbader, Joyce W -- Cirilli, Maurizio -- Lin, Chang -- Xu, Hong Wei -- Takuma, Kazuhiro -- Wang, Ning -- Caspersen, Casper -- Chen, Xi -- Pollak, Susan -- Chaney, Michael -- Trinchese, Fabrizio -- Liu, Shumin -- Gunn-Moore, Frank -- Lue, Lih-Fen -- Walker, Douglas G -- Kuppusamy, Periannan -- Zewier, Zay L -- Arancio, Ottavio -- Stern, David -- Yan, Shirley ShiDu -- Wu, Hao -- 1K07AG00959/AG/NIA NIH HHS/ -- AG16736/AG/NIA NIH HHS/ -- AG17490/AG/NIA NIH HHS/ -- NS42855/NS/NINDS NIH HHS/ -- P50AG08702/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2004 Apr 16;304(5669):448-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Reproductive Sciences and Department of Obstetrics and Gynecology, College of Physicians and Surgeons, Columbia University, 630 West 168th Street, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15087549" target="_blank"〉PubMed〈/a〉

    Description: Understanding gene expression requires the ability to follow the fate of individual molecules. Here we use a cellular system for monitoring messenger RNA (mRNA)expression to characterize the movement in real time of single mRNA-protein complexes (mRNPs) in the nucleus of living mammalian cells. This mobility was not directed but was governed by simple diffusion. Some mRNPs were partially corralled throughout the nonhomogenous nuclear environment, but no accumulation at subnuclear domains was observed. Following energy deprivation, energy-independent motion of mRNPs was observed in a highly ATP-dependent nuclear environment; movements were constrained to chromatin-poor domains and excluded by newly formed chromatin barriers. This observation resolves a controversy, showing that the energetic requirements of nuclear mRNP trafficking are consistent with a diffusional model.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4765737/" 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/PMC4765737/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shav-Tal, Yaron -- Darzacq, Xavier -- Shenoy, Shailesh M -- Fusco, Dahlene -- Janicki, Susan M -- Spector, David L -- Singer, Robert H -- DOE63056/PHS HHS/ -- EB2060/EB/NIBIB NIH HHS/ -- GM42694/GM/NIGMS NIH HHS/ -- R01 EB002060/EB/NIBIB NIH HHS/ -- R01 GM042694/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Jun 18;304(5678):1797-800.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Anatomy and Structural Biology and Cell Biology, Albert Einstein College of Medicine, Bronx, NY 10461, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15205532" target="_blank"〉PubMed〈/a〉
