    Bifurcation of lipid and protein kinase signals of PI3Kgamma to the protein kinases PKB and MAPK (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-10-09
    Description: Phosphoinositide 3-kinases (PI3Ks) activate protein kinase PKB (also termed Akt), and PI3Kgamma activated by heterotrimeric guanosine triphosphate-binding protein can stimulate mitogen-activated protein kinase (MAPK). Exchange of a putative lipid substrate-binding site generated PI3Kgamma proteins with altered or aborted lipid but retained protein kinase activity. Transiently expressed, PI3Kgamma hybrids exhibited wortmannin-sensitive activation of MAPK, whereas a catalytically inactive PI3Kgamma did not. Membrane-targeted PI3Kgamma constitutively produced phosphatidylinositol 3,4, 3,4,5-trisphosphate and activated PKB but not MAPK. Moreover, stimulation of MAPK in response to lysophosphatidic acid was blocked by catalytically inactive PI3Kgamma but not by hybrid PI3Kgammas. Thus, two major signals emerge from PI3Kgamma: phosphoinositides that target PKB and protein phosphorylation that activates MAPK.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bondeva, T -- Pirola, L -- Bulgarelli-Leva, G -- Rubio, I -- Wetzker, R -- Wymann, M P -- New York, N.Y. -- Science. 1998 Oct 9;282(5387):293-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Unit "Molecular Cell Biology," University of Jena, D-07747 Jena, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9765155" target="_blank"〉PubMed〈/a〉

    Secreted semaphorins control spine distribution and morphogenesis in the postnatal CNS (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-17
    Description: The majority of excitatory synapses in the mammalian CNS (central nervous system) are formed on dendritic spines, and spine morphology and distribution are critical for synaptic transmission, synaptic integration and plasticity. Here, we show that a secreted semaphorin, Sema3F, is a negative regulator of spine development and synaptic structure. Mice with null mutations in genes encoding Sema3F, and its holoreceptor components neuropilin-2 (Npn-2, also known as Nrp2) and plexin A3 (PlexA3, also known as Plxna3), exhibit increased dentate gyrus (DG) granule cell (GC) and cortical layer V pyramidal neuron spine number and size, and also aberrant spine distribution. Moreover, Sema3F promotes loss of spines and excitatory synapses in dissociated neurons in vitro, and in Npn-2(-/-) brain slices cortical layer V and DG GCs exhibit increased mEPSC (miniature excitatory postsynaptic current) frequency. In contrast, a distinct Sema3A-Npn-1/PlexA4 signalling cascade controls basal dendritic arborization in layer V cortical neurons, but does not influence spine morphogenesis or distribution. These disparate effects of secreted semaphorins are reflected in the restricted dendritic localization of Npn-2 to apical dendrites and of Npn-1 (also known as Nrp1) to all dendrites of cortical pyramidal neurons. Therefore, Sema3F signalling controls spine distribution along select dendritic processes, and distinct secreted semaphorin signalling events orchestrate CNS connectivity through the differential control of spine morphogenesis, synapse formation, and the elaboration of dendritic morphology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2842559/" 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/PMC2842559/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tran, Tracy S -- Rubio, Maria E -- Clem, Roger L -- Johnson, Dontais -- Case, Lauren -- Tessier-Lavigne, Marc -- Huganir, Richard L -- Ginty, David D -- Kolodkin, Alex L -- F32 NS051003/NS/NINDS NIH HHS/ -- P50 MH06883/MH/NIMH NIH HHS/ -- R01 DC-006881/DC/NIDCD NIH HHS/ -- R01 MH059199/MH/NIMH NIH HHS/ -- R01 MH059199-07/MH/NIMH NIH HHS/ -- R01 MH059199-08/MH/NIMH NIH HHS/ -- R01 MH059199-09/MH/NIMH NIH HHS/ -- R01 MH059199-10/MH/NIMH NIH HHS/ -- R01 MH59199/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 Dec 24;462(7276):1065-9. doi: 10.1038/nature08628.

    Notch and EGFR pathway interaction regulates neural stem cell number and self-renewal (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-09-17
    Description: Specialized cellular microenvironments, or 'niches', modulate stem cell properties, including cell number, self-renewal and fate decisions. In the adult brain, niches that maintain a source of neural stem cells (NSCs) and neural progenitor cells (NPCs) are the subventricular zone (SVZ) of the lateral ventricle and the dentate gyrus of the hippocampus. The size of the NSC population of the SVZ at any time is the result of several ongoing processes, including self-renewal, cell differentiation, and cell death. Maintaining the balance between NSCs and NPCs in the SVZ niche is critical to supply the brain with specific neural populations, both under normal conditions or after injury. A fundamental question relevant to both normal development and to cell-based repair strategies in the central nervous system is how the balance of different NSC and NPC populations is maintained in the niche. EGFR (epidermal growth factor receptor) and Notch signalling pathways have fundamental roles during development of multicellular organisms. In Drosophila and in Caenorhabditis elegans these pathways may have either cooperative or antagonistic functions. In the SVZ, Notch regulates NSC identity and self-renewal, whereas EGFR specifically affects NPC proliferation and migration. This suggests that interplay of these two pathways may maintain the balance between NSC and NPC numbers. Here we show that functional cell-cell interaction between NPCs and NSCs through EGFR and Notch signalling has a crucial role in maintaining the balance between these cell populations in the SVZ. Enhanced EGFR signalling in vivo results in the expansion of the NPC pool, and reduces NSC number and self-renewal. This occurs through a non-cell-autonomous mechanism involving EGFR-mediated regulation of Notch signalling. Our findings define a novel interaction between EGFR and Notch pathways in the adult SVZ, and thus provide a mechanism for NSC and NPC pool maintenance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2941915/" 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/PMC2941915/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aguirre, Adan -- Rubio, Maria E -- Gallo, Vittorio -- K99NS057944/NS/NINDS NIH HHS/ -- P30HD40677/HD/NICHD NIH HHS/ -- R00 NS057944/NS/NINDS NIH HHS/ -- R01 DC006881/DC/NIDCD NIH HHS/ -- R01 DC006881-03/DC/NIDCD NIH HHS/ -- R01 DC006881-04/DC/NIDCD NIH HHS/ -- R01DC006881/DC/NIDCD NIH HHS/ -- R01NS045702/NS/NINDS NIH HHS/ -- R01NS056427/NS/NINDS NIH HHS/ -- R0O NS057944-03/NS/NINDS NIH HHS/ -- England -- Nature. 2010 Sep 16;467(7313):323-7. doi: 10.1038/nature09347.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Neuroscience Research, Children's National Medical Center, Washington, District of Columbia 20010, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20844536" target="_blank"〉PubMed〈/a〉

    BRCA2 prevents R-loop accumulation and associates with TREX-2 mRNA export factor PCID2 (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-06-05
    Description: Genome instability is central to ageing, cancer and other diseases. It is not only proteins involved in DNA replication or the DNA damage response (DDR) that are important for maintaining genome integrity: from yeast to higher eukaryotes, mutations in genes involved in pre-mRNA splicing and in the biogenesis and export of messenger ribonucleoprotein (mRNP) also induce DNA damage and genome instability. This instability is frequently mediated by R-loops formed by DNA-RNA hybrids and a displaced single-stranded DNA. Here we show that the human TREX-2 complex, which is involved in mRNP biogenesis and export, prevents genome instability as determined by the accumulation of gamma-H2AX (Ser-139 phosphorylated histone H2AX) and 53BP1 foci and single-cell electrophoresis in cells depleted of the TREX-2 subunits PCID2, GANP and DSS1. We show that the BRCA2 repair factor, which binds to DSS1, also associates with PCID2 in the cell. The use of an enhanced green fluorescent protein-tagged hybrid-binding domain of RNase H1 and the S9.6 antibody did not detect R-loops in TREX-2-depleted cells, but did detect the accumulation of R-loops in BRCA2-depleted cells. The results indicate that R-loops are frequently formed in cells and that BRCA2 is required for their processing. This link between BRCA2 and RNA-mediated genome instability indicates that R-loops may be a chief source of replication stress and cancer-associated instability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bhatia, Vaibhav -- Barroso, Sonia I -- Garcia-Rubio, Maria L -- Tumini, Emanuela -- Herrera-Moyano, Emilia -- Aguilera, Andres -- England -- Nature. 2014 Jul 17;511(7509):362-5. doi: 10.1038/nature13374.

    Interpreting cancer genomes using systematic host network perturbations by tumour virus proteins (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-07-20
    Description: Genotypic differences greatly influence susceptibility and resistance to disease. Understanding genotype-phenotype relationships requires that phenotypes be viewed as manifestations of network properties, rather than simply as the result of individual genomic variations. Genome sequencing efforts have identified numerous germline mutations, and large numbers of somatic genomic alterations, associated with a predisposition to cancer. However, it remains difficult to distinguish background, or 'passenger', cancer mutations from causal, or 'driver', mutations in these data sets. Human viruses intrinsically depend on their host cell during the course of infection and can elicit pathological phenotypes similar to those arising from mutations. Here we test the hypothesis that genomic variations and tumour viruses may cause cancer through related mechanisms, by systematically examining host interactome and transcriptome network perturbations caused by DNA tumour virus proteins. The resulting integrated viral perturbation data reflects rewiring of the host cell networks, and highlights pathways, such as Notch signalling and apoptosis, that go awry in cancer. We show that systematic analyses of host targets of viral proteins can identify cancer genes with a success rate on a par with their identification through functional genomics and large-scale cataloguing of tumour mutations. Together, these complementary approaches increase the specificity of cancer gene identification. Combining systems-level studies of pathogen-encoded gene products with genomic approaches will facilitate the prioritization of cancer-causing driver genes to advance the understanding of the genetic basis of human cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3408847/" 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/PMC3408847/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rozenblatt-Rosen, Orit -- Deo, Rahul C -- Padi, Megha -- Adelmant, Guillaume -- Calderwood, Michael A -- Rolland, Thomas -- Grace, Miranda -- Dricot, Amelie -- Askenazi, Manor -- Tavares, Maria -- Pevzner, Samuel J -- Abderazzaq, Fieda -- Byrdsong, Danielle -- Carvunis, Anne-Ruxandra -- Chen, Alyce A -- Cheng, Jingwei -- Correll, Mick -- Duarte, Melissa -- Fan, Changyu -- Feltkamp, Mariet C -- Ficarro, Scott B -- Franchi, Rachel -- Garg, Brijesh K -- Gulbahce, Natali -- Hao, Tong -- Holthaus, Amy M -- James, Robert -- Korkhin, Anna -- Litovchick, Larisa -- Mar, Jessica C -- Pak, Theodore R -- Rabello, Sabrina -- Rubio, Renee -- Shen, Yun -- Singh, Saurav -- Spangle, Jennifer M -- Tasan, Murat -- Wanamaker, Shelly -- Webber, James T -- Roecklein-Canfield, Jennifer -- Johannsen, Eric -- Barabasi, Albert-Laszlo -- Beroukhim, Rameen -- Kieff, Elliott -- Cusick, Michael E -- Hill, David E -- Munger, Karl -- Marto, Jarrod A -- Quackenbush, John -- Roth, Frederick P -- DeCaprio, James A -- Vidal, Marc -- F32 GM095284/GM/NIGMS NIH HHS/ -- F32GM095284/GM/NIGMS NIH HHS/ -- K08 CA122833/CA/NCI NIH HHS/ -- K08 HL098361/HL/NHLBI NIH HHS/ -- K08HL098361/HL/NHLBI NIH HHS/ -- K25 HG006031/HG/NHGRI NIH HHS/ -- K25HG006031/HG/NHGRI NIH HHS/ -- P01 CA050661/CA/NCI NIH HHS/ -- P01CA050661/CA/NCI NIH HHS/ -- P50 HG004233/HG/NHGRI NIH HHS/ -- P50HG004233/HG/NHGRI NIH HHS/ -- R01 CA047006/CA/NCI NIH HHS/ -- R01 CA063113/CA/NCI NIH HHS/ -- R01 CA066980/CA/NCI NIH HHS/ -- R01 CA081135/CA/NCI NIH HHS/ -- R01 CA085180/CA/NCI NIH HHS/ -- R01 CA093804/CA/NCI NIH HHS/ -- R01 CA131354/CA/NCI NIH HHS/ -- R01 HG001715/HG/NHGRI NIH HHS/ -- R01CA047006/CA/NCI NIH HHS/ -- R01CA063113/CA/NCI NIH HHS/ -- R01CA066980/CA/NCI NIH HHS/ -- R01CA081135/CA/NCI NIH HHS/ -- R01CA085180/CA/NCI NIH HHS/ -- R01CA093804/CA/NCI NIH HHS/ -- R01CA131354/CA/NCI NIH HHS/ -- R01HG001715/HG/NHGRI NIH HHS/ -- T32 HL007208/HL/NHLBI NIH HHS/ -- T32HL007208/HL/NHLBI NIH HHS/ -- U01 CA141583/CA/NCI NIH HHS/ -- U01CA141583/CA/NCI NIH HHS/ -- England -- Nature. 2012 Jul 26;487(7408):491-5. doi: 10.1038/nature11288.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genomic Analysis of Network Perturbations Center of Excellence in Genomic Science, Dana-Farber Cancer Institute, Boston, Massachusetts 02215, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22810586" target="_blank"〉PubMed〈/a〉

    Analysis of Plasmodium falciparum diversity in natural infections by deep sequencing (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-06-23
    Description: Malaria elimination strategies require surveillance of the parasite population for genetic changes that demand a public health response, such as new forms of drug resistance. Here we describe methods for the large-scale analysis of genetic variation in Plasmodium falciparum by deep sequencing of parasite DNA obtained from the blood of patients with malaria, either directly or after short-term culture. Analysis of 86,158 exonic single nucleotide polymorphisms that passed genotyping quality control in 227 samples from Africa, Asia and Oceania provides genome-wide estimates of allele frequency distribution, population structure and linkage disequilibrium. By comparing the genetic diversity of individual infections with that of the local parasite population, we derive a metric of within-host diversity that is related to the level of inbreeding in the population. An open-access web application has been established for the exploration of regional differences in allele frequency and of highly differentiated loci in the P. falciparum genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3738909/" 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/PMC3738909/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Manske, Magnus -- Miotto, Olivo -- Campino, Susana -- Auburn, Sarah -- Almagro-Garcia, Jacob -- Maslen, Gareth -- O'Brien, Jack -- Djimde, Abdoulaye -- Doumbo, Ogobara -- Zongo, Issaka -- Ouedraogo, Jean-Bosco -- Michon, Pascal -- Mueller, Ivo -- Siba, Peter -- Nzila, Alexis -- Borrmann, Steffen -- Kiara, Steven M -- Marsh, Kevin -- Jiang, Hongying -- Su, Xin-Zhuan -- Amaratunga, Chanaki -- Fairhurst, Rick -- Socheat, Duong -- Nosten, Francois -- Imwong, Mallika -- White, Nicholas J -- Sanders, Mandy -- Anastasi, Elisa -- Alcock, Dan -- Drury, Eleanor -- Oyola, Samuel -- Quail, Michael A -- Turner, Daniel J -- Ruano-Rubio, Valentin -- Jyothi, Dushyanth -- Amenga-Etego, Lucas -- Hubbart, Christina -- Jeffreys, Anna -- Rowlands, Kate -- Sutherland, Colin -- Roper, Cally -- Mangano, Valentina -- Modiano, David -- Tan, John C -- Ferdig, Michael T -- Amambua-Ngwa, Alfred -- Conway, David J -- Takala-Harrison, Shannon -- Plowe, Christopher V -- Rayner, Julian C -- Rockett, Kirk A -- Clark, Taane G -- Newbold, Chris I -- Berriman, Matthew -- MacInnis, Bronwyn -- Kwiatkowski, Dominic P -- 075491/Z/04/Wellcome Trust/United Kingdom -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 082370/Wellcome Trust/United Kingdom -- 089275/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 090770/Wellcome Trust/United Kingdom -- 090770/Z/09/Z/Wellcome Trust/United Kingdom -- 092654/Wellcome Trust/United Kingdom -- 093956/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- 55005502/Howard Hughes Medical Institute/ -- G0600718/Medical Research Council/United Kingdom -- G19/9/Medical Research Council/United Kingdom -- Intramural NIH HHS/ -- England -- Nature. 2012 Jul 19;487(7407):375-9. doi: 10.1038/nature11174.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Hinxton, Cambridge CB10 1SA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22722859" target="_blank"〉PubMed〈/a〉

    Genetic risk and a primary role for cell-mediated immune mechanisms in multiple sclerosis (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-08-13
    Description: Multiple sclerosis is a common disease of the central nervous system in which the interplay between inflammatory and neurodegenerative processes typically results in intermittent neurological disturbance followed by progressive accumulation of disability. Epidemiological studies have shown that genetic factors are primarily responsible for the substantially increased frequency of the disease seen in the relatives of affected individuals, and systematic attempts to identify linkage in multiplex families have confirmed that variation within the major histocompatibility complex (MHC) exerts the greatest individual effect on risk. Modestly powered genome-wide association studies (GWAS) have enabled more than 20 additional risk loci to be identified and have shown that multiple variants exerting modest individual effects have a key role in disease susceptibility. Most of the genetic architecture underlying susceptibility to the disease remains to be defined and is anticipated to require the analysis of sample sizes that are beyond the numbers currently available to individual research groups. In a collaborative GWAS involving 9,772 cases of European descent collected by 23 research groups working in 15 different countries, we have replicated almost all of the previously suggested associations and identified at least a further 29 novel susceptibility loci. Within the MHC we have refined the identity of the HLA-DRB1 risk alleles and confirmed that variation in the HLA-A gene underlies the independent protective effect attributable to the class I region. Immunologically relevant genes are significantly overrepresented among those mapping close to the identified loci and particularly implicate T-helper-cell differentiation in the pathogenesis of multiple sclerosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3182531/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009"

    Cloning and characterization of a G protein-activated human phosphoinositide-3 kinase (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-08-04
    Description: Phosphoinositide-3 kinase activity is implicated in diverse cellular responses triggered by mammalian cell surface receptors and in the regulation of protein sorting in yeast. Receptors with intrinsic and associated tyrosine kinase activity recruit heterodimeric phosphoinositide-3 kinases that consist of p110 catalytic subunits and p85 adaptor molecules containing Src homology 2 (SH2) domains. A phosphoinositide-3 kinase isotype, p110 gamma, was cloned and characterized. The p110 gamma enzyme was activated in vitro by both the alpha and beta gamma subunits of heterotrimeric guanosine triphosphate (GTP)-binding proteins (G proteins) and did not interact with p85. A potential pleckstrin homology domain is located near its amino terminus. The p110 gamma isotype may link signaling through G protein-coupled receptors to the generation of phosphoinositide second messengers phosphorylated in the D-3 position.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stoyanov, B -- Volinia, S -- Hanck, T -- Rubio, I -- Loubtchenkov, M -- Malek, D -- Stoyanova, S -- Vanhaesebroeck, B -- Dhand, R -- Nurnberg, B -- New York, N.Y. -- Science. 1995 Aug 4;269(5224):690-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Research Unit in Growth Factor Signal Transduction, Medical Faculty, University of Jena, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624799" target="_blank"〉PubMed〈/a〉

    Sodium-driven potassium uptake by the plant potassium transporter HKT1 and mutations conferring salt tolerance (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-12-08
    Description: Sodium (Na+) at high millimolar concentrations in soils is toxic to most higher plants and severely reduces agricultural production worldwide. However, the molecular mechanisms for plant Na+ uptake remain unknown. Here, the wheat root high-affinity potassium (K+) uptake transporter HKT1 was shown to function as a high-affinity K(+)-Na+ cotransporter. High-affinity K+ uptake was activated by micromolar Na+ concentrations; moreover, high-affinity Na+ uptake was activated by K+ (half-activation constant, 2.8 microM K+). However, at physiologically detrimental concentrations of Na+, K+ accumulation mediated by HKT1 was blocked and low-affinity Na+ uptake occurred (Michaelis constant, approximately 16 mM Na+), which correlated to Na+ toxicity in plants. Point mutations in the sixth putative transmembrane domain of HKT1 that increase Na+ tolerance were isolated with the use of yeast as a screening system. Na+ uptake and Na+ inhibition of K+ accumulation indicate a possible role for HKT1 in physiological Na+ toxicity in plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rubio, F -- Gassmann, W -- Schroeder, J I -- New York, N.Y. -- Science. 1995 Dec 8;270(5242):1660-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of California, San Diego, La Jolla 92093-0116, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7502075" target="_blank"〉PubMed〈/a〉

    Bergmann glial AMPA receptors are required for fine motor coordination (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-07-07
    Description: The impact of glial neurotransmitter receptors in vivo is still elusive. In the cerebellum, Bergmann glial (BG) cells express alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-type glutamate receptors (AMPARs) composed exclusively of GluA1 and/or GluA4 subunits. With the use of conditional gene inactivation, we found that the majority of cerebellar GluA1/A4-type AMPARs are expressed in BG cells. In young mice, deletion of BG AMPARs resulted in retraction of glial appendages from Purkinje cell (PC) synapses, increased amplitude and duration of evoked PC currents, and a delayed formation of glutamatergic synapses. In adult mice, AMPAR inactivation also caused retraction of glial processes. The physiological and structural changes were accompanied by behavioral impairments in fine motor coordination. Thus, BG AMPARs are essential to optimize synaptic integration and cerebellar output function throughout life.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saab, Aiman S -- Neumeyer, Alexander -- Jahn, Hannah M -- Cupido, Alexander -- Simek, Antonia A M -- Boele, Henk-Jan -- Scheller, Anja -- Le Meur, Karim -- Gotz, Magdalena -- Monyer, Hannah -- Sprengel, Rolf -- Rubio, Maria E -- Deitmer, Joachim W -- De Zeeuw, Chris I -- Kirchhoff, Frank -- R01-DC006881/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 2012 Aug 10;337(6095):749-53. doi: 10.1126/science.1221140.
