    Prevention of organ allograft rejection by a specific Janus kinase 3 inhibitor (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-01
    Description: Because of its requirement for signaling by multiple cytokines, Janus kinase 3 (JAK3) is an excellent target for clinical immunosuppression. We report the development of a specific, orally active inhibitor of JAK3, CP-690,550, that significantly prolonged survival in a murine model of heart transplantation and in cynomolgus monkeys receiving kidney transplants. CP-690,550 treatment was not associated with hypertension, hyperlipidemia, or lymphoproliferative disease. On the basis of these preclinical results, we believe JAK3 blockade by CP-690,550 has potential for therapeutically desirable immunosuppression in human organ transplantation and in other clinical settings.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Changelian, Paul S -- Flanagan, Mark E -- Ball, Douglas J -- Kent, Craig R -- Magnuson, Kelly S -- Martin, William H -- Rizzuti, Bonnie J -- Sawyer, Perry S -- Perry, Bret D -- Brissette, William H -- McCurdy, Sandra P -- Kudlacz, Elizabeth M -- Conklyn, Maryrose J -- Elliott, Eileen A -- Koslov, Erika R -- Fisher, Michael B -- Strelevitz, Timothy J -- Yoon, Kwansik -- Whipple, David A -- Sun, Jianmin -- Munchhof, Michael J -- Doty, John L -- Casavant, Jeffrey M -- Blumenkopf, Todd A -- Hines, Michael -- Brown, Matthew F -- Lillie, Brett M -- Subramanyam, Chakrapani -- Shang-Poa, Chang -- Milici, Anthony J -- Beckius, Gretchen E -- Moyer, James D -- Su, Chunyan -- Woodworth, Thasia G -- Gaweco, Anderson S -- Beals, Chan R -- Littman, Bruce H -- Fisher, Douglas A -- Smith, James F -- Zagouras, Panayiotis -- Magna, Holly A -- Saltarelli, Mary J -- Johnson, Kimberly S -- Nelms, Linda F -- Des Etages, Shelley G -- Hayes, Lisa S -- Kawabata, Thomas T -- Finco-Kent, Deborah -- Baker, Deanna L -- Larson, Michael -- Si, Ming-Sing -- Paniagua, Ricardo -- Higgins, John -- Holm, Bari -- Reitz, Bruce -- Zhou, Yong-Jie -- Morris, Randall E -- O'Shea, John J -- Borie, Dominic C -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):875-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immunology Group, Department of Antibacterials and Immunology, Pfizer Global Researchand Development, Groton, CT 06340, USA. paul_s_changelian@groton.pfizer.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14593182" target="_blank"〉PubMed〈/a〉

    Human chromosome 7: DNA sequence and biology (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-04-12
    Description: DNA sequence and annotation of the entire human chromosome 7, encompassing nearly 158 million nucleotides of DNA and 1917 gene structures, are presented. To generate a higher order description, additional structural features such as imprinted genes, fragile sites, and segmental duplications were integrated at the level of the DNA sequence with medical genetic data, including 440 chromosome rearrangement breakpoints associated with disease. This approach enabled the discovery of candidate genes for developmental diseases including autism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2882961/" 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/PMC2882961/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scherer, Stephen W -- Cheung, Joseph -- MacDonald, Jeffrey R -- Osborne, Lucy R -- Nakabayashi, Kazuhiko -- Herbrick, Jo-Anne -- Carson, Andrew R -- Parker-Katiraee, Layla -- Skaug, Jennifer -- Khaja, Razi -- Zhang, Junjun -- Hudek, Alexander K -- Li, Martin -- Haddad, May -- Duggan, Gavin E -- Fernandez, Bridget A -- Kanematsu, Emiko -- Gentles, Simone -- Christopoulos, Constantine C -- Choufani, Sanaa -- Kwasnicka, Dorota -- Zheng, Xiangqun H -- Lai, Zhongwu -- Nusskern, Deborah -- Zhang, Qing -- Gu, Zhiping -- Lu, Fu -- Zeesman, Susan -- Nowaczyk, Malgorzata J -- Teshima, Ikuko -- Chitayat, David -- Shuman, Cheryl -- Weksberg, Rosanna -- Zackai, Elaine H -- Grebe, Theresa A -- Cox, Sarah R -- Kirkpatrick, Susan J -- Rahman, Nazneen -- Friedman, Jan M -- Heng, Henry H Q -- Pelicci, Pier Giuseppe -- Lo-Coco, Francesco -- Belloni, Elena -- Shaffer, Lisa G -- Pober, Barbara -- Morton, Cynthia C -- Gusella, James F -- Bruns, Gail A P -- Korf, Bruce R -- Quade, Bradley J -- Ligon, Azra H -- Ferguson, Heather -- Higgins, Anne W -- Leach, Natalia T -- Herrick, Steven R -- Lemyre, Emmanuelle -- Farra, Chantal G -- Kim, Hyung-Goo -- Summers, Anne M -- Gripp, Karen W -- Roberts, Wendy -- Szatmari, Peter -- Winsor, Elizabeth J T -- Grzeschik, Karl-Heinz -- Teebi, Ahmed -- Minassian, Berge A -- Kere, Juha -- Armengol, Lluis -- Pujana, Miguel Angel -- Estivill, Xavier -- Wilson, Michael D -- Koop, Ben F -- Tosi, Sabrina -- Moore, Gudrun E -- Boright, Andrew P -- Zlotorynski, Eitan -- Kerem, Batsheva -- Kroisel, Peter M -- Petek, Erwin -- Oscier, David G -- Mould, Sarah J -- Dohner, Hartmut -- Dohner, Konstanze -- Rommens, Johanna M -- Vincent, John B -- Venter, J Craig -- Li, Peter W -- Mural, Richard J -- Adams, Mark D -- Tsui, Lap-Chee -- 38103/Canadian Institutes of Health Research/Canada -- P01 GM061354/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 May 2;300(5620):767-72.

    Mutations in dynein link motor neuron degeneration to defects in retrograde transport (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-06
    Description: Degenerative disorders of motor neurons include a range of progressive fatal diseases such as amyotrophic lateral sclerosis (ALS), spinal-bulbar muscular atrophy (SBMA), and spinal muscular atrophy (SMA). Although the causative genetic alterations are known for some cases, the molecular basis of many SMA and SBMA-like syndromes and most ALS cases is unknown. Here we show that missense point mutations in the cytoplasmic dynein heavy chain result in progressive motor neuron degeneration in heterozygous mice, and in homozygotes this is accompanied by the formation of Lewy-like inclusion bodies, thus resembling key features of human pathology. These mutations exclusively perturb neuron-specific functions of dynein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hafezparast, Majid -- Klocke, Rainer -- Ruhrberg, Christiana -- Marquardt, Andreas -- Ahmad-Annuar, Azlina -- Bowen, Samantha -- Lalli, Giovanna -- Witherden, Abi S -- Hummerich, Holger -- Nicholson, Sharon -- Morgan, P Jeffrey -- Oozageer, Ravi -- Priestley, John V -- Averill, Sharon -- King, Von R -- Ball, Simon -- Peters, Jo -- Toda, Takashi -- Yamamoto, Ayumu -- Hiraoka, Yasushi -- Augustin, Martin -- Korthaus, Dirk -- Wattler, Sigrid -- Wabnitz, Philipp -- Dickneite, Carmen -- Lampel, Stefan -- Boehme, Florian -- Peraus, Gisela -- Popp, Andreas -- Rudelius, Martina -- Schlegel, Juergen -- Fuchs, Helmut -- Hrabe de Angelis, Martin -- Schiavo, Giampietro -- Shima, David T -- Russ, Andreas P -- Stumm, Gabriele -- Martin, Joanne E -- Fisher, Elizabeth M C -- New York, N.Y. -- Science. 2003 May 2;300(5620):808-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurodegenerative Disease, Institute of Neurology, National Hospital for Neurology and Neurosurgery, Queen Square, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12730604" target="_blank"〉PubMed〈/a〉

    Design and chemical synthesis of a homogeneous polymer-modified erythropoiesis protein (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-02-08
    Description: We report the design and total chemical synthesis of "synthetic erythropoiesis protein" (SEP), a 51-kilodalton protein-polymer construct consisting of a 166-amino-acid polypeptide chain and two covalently attached, branched, and monodisperse polymer moieties that are negatively charged. The ability to control the chemistry allowed us to synthesize a macromolecule of precisely defined covalent structure. SEP was homogeneous as shown by high-resolution analytical techniques, with a mass of 50,825 +/-10 daltons by electrospray mass spectrometry, and with a pI of 5.0. In cell and animal assays for erythropoiesis, SEP displayed potent biological activity and had significantly prolonged duration of action in vivo. These chemical methods are a powerful tool in the rational design of protein constructs with potential therapeutic applications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kochendoerfer, Gerd G -- Chen, Shiah-Yun -- Mao, Feng -- Cressman, Sonya -- Traviglia, Stacey -- Shao, Haiyan -- Hunter, Christie L -- Low, Donald W -- Cagle, E Neil -- Carnevali, Maia -- Gueriguian, Vincent -- Keogh, Peter J -- Porter, Heather -- Stratton, Stephen M -- Wiedeke, M Con -- Wilken, Jill -- Tang, Jie -- Levy, Jay J -- Miranda, Les P -- Crnogorac, Milan M -- Kalbag, Suresh -- Botti, Paolo -- Schindler-Horvat, Janice -- Savatski, Laura -- Adamson, John W -- Kung, Ada -- Kent, Stephen B H -- Bradburne, James A -- New York, N.Y. -- Science. 2003 Feb 7;299(5608):884-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Gryphon Therapeutics, 250 East Grand Avenue, Suite 90, South San Francisco, CA 94080, USA.

    Melanopsin is required for non-image-forming photic responses in blind mice (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-06-28
    Description: Although mice lacking rod and cone photoreceptors are blind, they retain many eye-mediated responses to light, possibly through photosensitive retinal ganglion cells. These cells express melanopsin, a photopigment that confers this photosensitivity. Mice lacking melanopsin still retain nonvisual photoreception, suggesting that rods and cones could operate in this capacity. We observed that mice with both outer-retinal degeneration and a deficiency in melanopsin exhibited complete loss of photoentrainment of the circadian oscillator, pupillary light responses, photic suppression of arylalkylamine-N-acetyltransferase transcript, and acute suppression of locomotor activity by light. This indicates the importance of both nonvisual and classical visual photoreceptor systems for nonvisual photic responses in mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Panda, Satchidananda -- Provencio, Ignacio -- Tu, Daniel C -- Pires, Susana S -- Rollag, Mark D -- Castrucci, Ana Maria -- Pletcher, Mathew T -- Sato, Trey K -- Wiltshire, Tim -- Andahazy, Mary -- Kay, Steve A -- Van Gelder, Russell N -- Hogenesch, John B -- K08-EY00403/EY/NEI NIH HHS/ -- MH 62405/MH/NIMH NIH HHS/ -- MH51573/MH/NIMH NIH HHS/ -- R01-EY14988/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2003 Jul 25;301(5632):525-7.

    CB1 cannabinoid receptors and on-demand defense against excitotoxicity (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-10-04
    Description: Abnormally high spiking activity can damage neurons. Signaling systems to protect neurons from the consequences of abnormal discharge activity have been postulated. We generated conditional mutant mice that lack expression of the cannabinoid receptor type 1 in principal forebrain neurons but not in adjacent inhibitory interneurons. In mutant mice,the excitotoxin kainic acid (KA) induced excessive seizures in vivo. The threshold to KA-induced neuronal excitation in vitro was severely reduced in hippocampal pyramidal neurons of mutants. KA administration rapidly raised hippocampal levels of anandamide and induced protective mechanisms in wild-type principal hippocampal neurons. These protective mechanisms could not be triggered in mutant mice. The endogenous cannabinoid system thus provides on-demand protection against acute excitotoxicity in central nervous system neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marsicano, Giovanni -- Goodenough, Sharon -- Monory, Krisztina -- Hermann, Heike -- Eder, Matthias -- Cannich, Astrid -- Azad, Shahnaz C -- Cascio, Maria Grazia -- Gutierrez, Silvia Ortega -- van der Stelt, Mario -- Lopez-Rodriguez, Maria Luz -- Casanova, Emilio -- Schutz, Gunther -- Zieglgansberger, Walter -- Di Marzo, Vincenzo -- Behl, Christian -- Lutz, Beat -- New York, N.Y. -- Science. 2003 Oct 3;302(5642):84-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Genetics of Behaviour, Max-Planck-Institute of Psychiatry, Kraepelinstrabetae 2-10, 80804 Munich, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14526074" target="_blank"〉PubMed〈/a〉

    Wild-type nonneuronal cells extend survival of SOD1 mutant motor neurons in ALS mice (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-10-04
    Description: The most common inherited [correct] form of amyotrophic lateral sclerosis (ALS), a neurodegenerative disease affecting adult motor neurons, is caused by dominant mutations in the ubiquitously expressed Cu-Zn superoxide dismutase (SOD1). In chimeric mice that are mixtures of normal and SOD1 mutant-expressing cells, toxicity to motor neurons is shown to require damage from mutant SOD1 acting within nonneuronal cells. Normal motor neurons in SOD1 mutant chimeras develop aspects of ALS pathology. Most important, nonneuronal cells that do not express mutant SOD1 delay degeneration and significantly extend survival of mutant-expressing motor neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clement, A M -- Nguyen, M D -- Roberts, E A -- Garcia, M L -- Boillee, S -- Rule, M -- McMahon, A P -- Doucette, W -- Siwek, D -- Ferrante, R J -- Brown, R H Jr -- Julien, J-P -- Goldstein, L S B -- Cleveland, D W -- AG 12992/AG/NIA NIH HHS/ -- AG 13846/AG/NIA NIH HHS/ -- HD 30249/HD/NICHD NIH HHS/ -- NS 27036/NS/NINDS NIH HHS/ -- NS 31248/NS/NINDS NIH HHS/ -- NS 37912/NS/NINDS NIH HHS/ -- R37 NS027036/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Oct 3;302(5642):113-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ludwig Institute for Cancer Research, University of California, 9500 Gilman Drive, La Jolla, CA 92093-0670, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14526083" target="_blank"〉PubMed〈/a〉

    Roles of NPM2 in chromatin and nucleolar organization in oocytes and embryos (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-04-26
    Description: Upon fertilization, remodeling of condensed maternal and paternal gamete DNA occurs to form the diploid genome. In Xenopus laevis, nucleoplasmin 2 (NPM2) decondenses sperm DNA in vitro. To study chromatin remodeling in vivo, we isolated mammalian NPM2 orthologs. Mouse NPM2 accumulates in oocyte nuclei and persists in preimplantation embryos. Npm2 knockout females have fertility defects owing to failed preimplantation embryo development. Although sperm DNA decondensation proceeds without NPM2, abnormalities are evident in oocyte and early embryonic nuclei. These defects include an absence of coalesced nucleolar structures and loss of heterochromatin and deacetylated histone H3 that normally circumscribe nucleoli in oocytes and early embryos, respectively. Thus, Npm2 is a maternal effect gene critical for nuclear and nucleolar organization and embryonic development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burns, Kathleen H -- Viveiros, Maria M -- Ren, Yongsheng -- Wang, Pei -- DeMayo, Francesco J -- Frail, Donald E -- Eppig, John J -- Matzuk, Martin M -- HD07495/HD/NICHD NIH HHS/ -- HD21970/HD/NICHD NIH HHS/ -- HD33438/HD/NICHD NIH HHS/ -- HD42500/HD/NICHD NIH HHS/ -- T32GM07330/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Apr 25;300(5619):633-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Baylor College of Medicine, One Baylor Plaza, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12714744" target="_blank"〉PubMed〈/a〉

    Polyubiquitination of p53 by a ubiquitin ligase activity of p300 (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-04-12
    Description: Rapid turnover of the tumor suppressor protein p53 requires the MDM2 ubiquitin ligase, and both interact with p300-CREB-binding protein transcriptional coactivator proteins. p53 is stabilized by the binding of p300 to the oncoprotein E1A, suggesting that p300 regulates p53 degradation. Purified p300 exhibited intrinsic ubiquitin ligase activity that was inhibited by E1A. In vitro, p300 with MDM2 catalyzed p53 polyubiquitination, whereas MDM2 catalyzed p53 monoubiquitination. E1A expression caused a decrease in polyubiquitinated but not monoubiquitinated p53 in cells. Thus, generation of the polyubiquitinated forms of p53 that are targeted for proteasome degradation requires the intrinsic ubiquitin ligase activities of MDM2 and p300.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grossman, Steven R -- Deato, Maria E -- Brignone, Chrystelle -- Chan, Ho Man -- Kung, Andrew L -- Tagami, Hideaki -- Nakatani, Yoshihiro -- Livingston, David M -- CA15751/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2003 Apr 11;300(5617):342-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cancer Biology, 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/12690203" target="_blank"〉PubMed〈/a〉

    Description: Stimulation of Toll-like receptors (TLRs) triggers activation of a common MyD88-dependent signaling pathway as well as a MyD88-independent pathway that is unique to TLR3 and TLR4 signaling pathways leading to interferon (IFN)-beta production. Here we disrupted the gene encoding a Toll/IL-1 receptor (TIR) domain-containing adaptor, TRIF. TRIF-deficient mice were defective in both TLR3- and TLR4-mediated expression of IFN-beta and activation of IRF-3. Furthermore, inflammatory cytokine production in response to the TLR4 ligand, but not to other TLR ligands, was severely impaired in TRIF-deficient macrophages. Mice deficient in both MyD88 and TRIF showed complete loss of nuclear factor kappa B activation in response to TLR4 stimulation. These findings demonstrate that TRIF is essential for TLR3- and TLR4-mediated signaling pathways facilitating mammalian antiviral host defense.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamamoto, Masahiro -- Sato, Shintaro -- Hemmi, Hiroaki -- Hoshino, Katsuaki -- Kaisho, Tsuneyasu -- Sanjo, Hideki -- Takeuchi, Osamu -- Sugiyama, Masanaka -- Okabe, Masaru -- Takeda, Kiyoshi -- Akira, Shizuo -- New York, N.Y. -- Science. 2003 Aug 1;301(5633):640-3.
