    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.

    Plant cuticular lipid export requires an ABC transporter (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-10-23
    Description: A waxy protective cuticle coats all primary aerial plant tissues. Its synthesis requires extensive export of lipids from epidermal cells to the plant surface. Arabidopsis cer5 mutants had reduced stem cuticular wax loads and accumulated sheetlike inclusions in the cytoplasm of wax-secreting cells. These inclusions represented abnormal deposits of cuticular wax and resembled inclusions found in a human disorder caused by a defective peroxisomal adenosine triphosphate binding cassette (ABC) transporter. We found that the CER5 gene encodes an ABC transporter localized in the plasma membrane of epidermal cells and conclude that it is required for wax export to the cuticle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pighin, Jamie A -- Zheng, Huanquan -- Balakshin, Laura J -- Goodman, Ian P -- Western, Tamara L -- Jetter, Reinhard -- Kunst, Ljerka -- Samuels, A Lacey -- New York, N.Y. -- Science. 2004 Oct 22;306(5696):702-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Botany, University of British Columbia (UBC), 6270 University Boulevard, Vancouver, BC V6T 1Z4, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15499022" target="_blank"〉PubMed〈/a〉

    Stress-dependent regulation of FOXO transcription factors by the SIRT1 deacetylase (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-21
    Description: The Sir2 deacetylase modulates organismal life-span in various species. However, the molecular mechanisms by which Sir2 increases longevity are largely unknown. We show that in mammalian cells, the Sir2 homolog SIRT1 appears to control the cellular response to stress by regulating the FOXO family of Forkhead transcription factors, a family of proteins that function as sensors of the insulin signaling pathway and as regulators of organismal longevity. SIRT1 and the FOXO transcription factor FOXO3 formed a complex in cells in response to oxidative stress, and SIRT1 deacetylated FOXO3 in vitro and within cells. SIRT1 had a dual effect on FOXO3 function: SIRT1 increased FOXO3's ability to induce cell cycle arrest and resistance to oxidative stress but inhibited FOXO3's ability to induce cell death. Thus, one way in which members of the Sir2 family of proteins may increase organismal longevity is by tipping FOXO-dependent responses away from apoptosis and toward stress resistance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brunet, Anne -- Sweeney, Lora B -- Sturgill, J Fitzhugh -- Chua, Katrin F -- Greer, Paul L -- Lin, Yingxi -- Tran, Hien -- Ross, Sarah E -- Mostoslavsky, Raul -- Cohen, Haim Y -- Hu, Linda S -- Cheng, Hwei-Ling -- Jedrychowski, Mark P -- Gygi, Steven P -- Sinclair, David A -- Alt, Frederick W -- Greenberg, Michael E -- NIHP30-HD18655/HD/NICHD NIH HHS/ -- P01 NS35138-17/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2004 Mar 26;303(5666):2011-5.

    Global mapping of the yeast genetic interaction network (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-07
    Description: A genetic interaction network containing approximately 1000 genes and approximately 4000 interactions was mapped by crossing mutations in 132 different query genes into a set of approximately 4700 viable gene yeast deletion mutants and scoring the double mutant progeny for fitness defects. Network connectivity was predictive of function because interactions often occurred among functionally related genes, and similar patterns of interactions tended to identify components of the same pathway. The genetic network exhibited dense local neighborhoods; therefore, the position of a gene on a partially mapped network is predictive of other genetic interactions. Because digenic interactions are common in yeast, similar networks may underlie the complex genetics associated with inherited phenotypes in other organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tong, Amy Hin Yan -- Lesage, Guillaume -- Bader, Gary D -- Ding, Huiming -- Xu, Hong -- Xin, Xiaofeng -- Young, James -- Berriz, Gabriel F -- Brost, Renee L -- Chang, Michael -- Chen, YiQun -- Cheng, Xin -- Chua, Gordon -- Friesen, Helena -- Goldberg, Debra S -- Haynes, Jennifer -- Humphries, Christine -- He, Grace -- Hussein, Shamiza -- Ke, Lizhu -- Krogan, Nevan -- Li, Zhijian -- Levinson, Joshua N -- Lu, Hong -- Menard, Patrice -- Munyana, Christella -- Parsons, Ainslie B -- Ryan, Owen -- Tonikian, Raffi -- Roberts, Tania -- Sdicu, Anne-Marie -- Shapiro, Jesse -- Sheikh, Bilal -- Suter, Bernhard -- Wong, Sharyl L -- Zhang, Lan V -- Zhu, Hongwei -- Burd, Christopher G -- Munro, Sean -- Sander, Chris -- Rine, Jasper -- Greenblatt, Jack -- Peter, Matthias -- Bretscher, Anthony -- Bell, Graham -- Roth, Frederick P -- Brown, Grant W -- Andrews, Brenda -- Bussey, Howard -- Boone, Charles -- GM39066/GM/NIGMS NIH HHS/ -- GM61221/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 6;303(5659):808-13.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Banting and Best Department of Medical Research, University of Toronto, Toronto, ON, Canada M5G 1L6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14764870" target="_blank"〉PubMed〈/a〉

    Host-parasite coevolutionary conflict between Arabidopsis and downy mildew (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-14
    Description: Plants are constantly exposed to attack by an array of diverse pathogens but lack a somatically adaptive immune system. In spite of this, natural plant populations do not often suffer destructive disease epidemics. Elucidating how allelic diversity within plant genes that function to detect pathogens (resistance genes) counteracts changing structures of pathogen genes required for host invasion (pathogenicity effectors) is critical to our understanding of the dynamics of natural plant populations. The RPP13 resistance gene is the most polymorphic gene analyzed to date in the model plant Arabidopsis thaliana. Here we report the cloning of the avirulence gene, ATR13, that triggers RPP13-mediated resistance, and we show that it too exhibits extreme levels of amino acid polymorphism. Evidence of diversifying selection visible in both components suggests that the host and pathogen may be locked in a coevolutionary conflict at these loci, where attempts to evade host resistance by the pathogen are matched by the development of new detection capabilities by the host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Allen, Rebecca L -- Bittner-Eddy, Peter D -- Grenville-Briggs, Laura J -- Meitz, Julia C -- Rehmany, Anne P -- Rose, Laura E -- Beynon, Jim L -- New York, N.Y. -- Science. 2004 Dec 10;306(5703):1957-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Warwick, HRI University of Warwick, Wellesbourne, Warwick, CV35 9EF, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15591208" target="_blank"〉PubMed〈/a〉

    Acetylation by Tip60 is required for selective histone variant exchange at DNA lesions (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-11-06
    Description: Phosphorylation of the human histone variant H2A.X and H2Av, its homolog in Drosophila melanogaster, occurs rapidly at sites of DNA double-strand breaks. Little is known about the function of this phosphorylation or its removal during DNA repair. Here, we demonstrate that the Drosophila Tip60 (dTip60) chromatin-remodeling complex acetylates nucleosomal phospho-H2Av and exchanges it with an unmodified H2Av. Both the histone acetyltransferase dTip60 as well as the adenosine triphosphatase Domino/p400 catalyze the exchange of phospho-H2Av. Thus, these data reveal a previously unknown mechanism for selective histone exchange that uses the concerted action of two distinct chromatin-remodeling enzymes within the same multiprotein complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kusch, Thomas -- Florens, Laurence -- Macdonald, W Hayes -- Swanson, Selene K -- Glaser, Robert L -- Yates, John R 3rd -- Abmayr, Susan M -- Washburn, Michael P -- Workman, Jerry L -- New York, N.Y. -- Science. 2004 Dec 17;306(5704):2084-7.

    Reflectins: the unusual proteins of squid reflective tissues (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-01-13
    Description: A family of unusual proteins is deposited in flat, structural platelets in reflective tissues of the squid Euprymna scolopes. These proteins, which we have named reflectins, are encoded by at least six genes in three subfamilies and have no reported homologs outside of squids. Reflectins possess five repeating domains, which are highly conserved among members of the family. The proteins have a very unusual composition, with four relatively rare residues (tyrosine, methionine, arginine, and tryptophan) comprising approximately 57% of a reflectin, and several common residues (alanine, isoleucine, leucine, and lysine) occurring in none of the family members. These protein-based reflectors in squids provide a marked example of nanofabrication in animal systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crookes, Wendy J -- Ding, Lin-Lin -- Huang, Qing Ling -- Kimbell, Jennifer R -- Horwitz, Joseph -- McFall-Ngai, Margaret J -- NEI R01 EY3897/EY/NEI NIH HHS/ -- R01 A150661/PHS HHS/ -- New York, N.Y. -- Science. 2004 Jan 9;303(5655):235-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Kewalo Marine Laboratory, Pacific Biomedical Research Center, University of Hawaii-Manoa, 41 Ahui Street, Honolulu, HI 96813, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14716016" target="_blank"〉PubMed〈/a〉

    SUMO modification of Huntingtin and Huntington's disease pathology (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-06
    Description: Huntington's disease (HD) is characterized by the accumulation of a pathogenic protein, Huntingtin (Htt), that contains an abnormal polyglutamine expansion. Here, we report that a pathogenic fragment of Htt (Httex1p) can be modified either by small ubiquitin-like modifier (SUMO)-1 or by ubiquitin on identical lysine residues. In cultured cells, SUMOylation stabilizes Httex1p, reduces its ability to form aggregates, and promotes its capacity to repress transcription. In a Drosophila model of HD, SUMOylation of Httex1p exacerbates neurodegeneration, whereas ubiquitination of Httex1p abrogates neurodegeneration. Lysine mutations that prevent both SUMOylation and ubiquitination of Httex1p reduce HD pathology, indicating that the contribution of SUMOylation to HD pathology extends beyond preventing Htt ubiquitination and degradation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steffan, Joan S -- Agrawal, Namita -- Pallos, Judit -- Rockabrand, Erica -- Trotman, Lloyd C -- Slepko, Natalia -- Illes, Katalin -- Lukacsovich, Tamas -- Zhu, Ya-Zhen -- Cattaneo, Elena -- Pandolfi, Pier Paolo -- Thompson, Leslie Michels -- Marsh, J Lawrence -- CA-62203/CA/NCI NIH HHS/ -- HD36049/HD/NICHD NIH HHS/ -- HD36081/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2004 Apr 2;304(5667):100-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry and Human Behavior, Gillespie 2121, University of California, Irvine, CA 92697, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15064418" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-01-31
    Description: The lantibiotic lacticin 481 is synthesized on ribosomes as a prepeptide (LctA) and posttranslationally modified to its mature form. These modifications include dehydration of serines and threonines, followed by intramolecular addition of cysteines to the unsaturated amino acids, which generates cyclic thioethers. This process breaks eight chemical bonds and forms six newbonds and is catalyzed by one enzyme, LctM. We have characterized the in vitro activity of LctM, which completely processed a series of LctA mutants, displaying a permissive substrate specificity that holds promise for antibiotic engineering.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xie, Lili -- Miller, Leah M -- Chatterjee, Champak -- Averin, Olga -- Kelleher, Neil L -- van der Donk, Wilfred A -- GM 067725/GM/NIGMS NIH HHS/ -- GM58822/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Jan 30;303(5658):679-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Illinois at Urbana-Champaign, 600 S.

    Modulation of Th1 activation and inflammation by the NF-kappaB repressor Foxj1 (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-14
    Description: Forkhead transcription factors play key roles in the regulation of immune responses. Here, we identify a role for one member of this family, Foxj1, in the regulation of T cell activation and autoreactivity. Foxj1 deficiency resulted in multiorgan systemic inflammation, exaggerated Th1 cytokine production, and T cell proliferation in autologous mixed lymphocyte reactions. Foxj1 suppressed NF-kappaB transcription activity in vitro, and Foxj1-deficient T cells possessed increased NF-kappaB activity in vivo, correlating with the ability of Foxj1 to regulate IkappaB proteins, particularly IkappaBbeta. Thus, Foxj1 likely modulates inflammatory reactions and prevents autoimmunity by antagonizing proinflammatory transcriptional activities. These results suggest a potentially general role for forkhead genes in the enforcement of lymphocyte quiescence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Ling -- Spoor, Melanie S -- Gerth, Andrea J -- Brody, Steven L -- Peng, Stanford L -- AI01803/AI/NIAID NIH HHS/ -- AI057471/AI/NIAID NIH HHS/ -- DK52574/DK/NIDDK NIH HHS/ -- HL56244/HL/NHLBI NIH HHS/ -- HL63988/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 13;303(5660):1017-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Rheumatology, Department of Internal Medicine, Washington University School of Medicine, 660 South Euclid Avenue, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14963332" target="_blank"〉PubMed〈/a〉
