    Antifungal drug resistance evoked via RNAi-dependent epimutations (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-08-01
    Description: Microorganisms evolve via a range of mechanisms that may include or involve sexual/parasexual reproduction, mutators, aneuploidy, Hsp90 and even prions. Mechanisms that may seem detrimental can be repurposed to generate diversity. Here we show that the human fungal pathogen Mucor circinelloides develops spontaneous resistance to the antifungal drug FK506 (tacrolimus) via two distinct mechanisms. One involves Mendelian mutations that confer stable drug resistance; the other occurs via an epigenetic RNA interference (RNAi)-mediated pathway resulting in unstable drug resistance. The peptidylprolyl isomerase FKBP12 interacts with FK506 forming a complex that inhibits the protein phosphatase calcineurin. Calcineurin inhibition by FK506 blocks M. circinelloides transition to hyphae and enforces yeast growth. Mutations in the fkbA gene encoding FKBP12 or the calcineurin cnbR or cnaA genes confer FK506 resistance and restore hyphal growth. In parallel, RNAi is spontaneously triggered to silence the fkbA gene, giving rise to drug-resistant epimutants. FK506-resistant epimutants readily reverted to the drug-sensitive wild-type phenotype when grown without exposure to the drug. The establishment of these epimutants is accompanied by generation of abundant fkbA small RNAs and requires the RNAi pathway as well as other factors that constrain or reverse the epimutant state. Silencing involves the generation of a double-stranded RNA trigger intermediate using the fkbA mature mRNA as a template to produce antisense fkbA RNA. This study uncovers a novel epigenetic RNAi-based epimutation mechanism controlling phenotypic plasticity, with possible implications for antimicrobial drug resistance and RNAi-regulatory mechanisms in fungi and other eukaryotes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4177005/" 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/PMC4177005/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Calo, Silvia -- Shertz-Wall, Cecelia -- Lee, Soo Chan -- Bastidas, Robert J -- Nicolas, Francisco E -- Granek, Joshua A -- Mieczkowski, Piotr -- Torres-Martinez, Santiago -- Ruiz-Vazquez, Rosa M -- Cardenas, Maria E -- Heitman, Joseph -- R01 AI039115/AI/NIAID NIH HHS/ -- R01 AI50438-10/AI/NIAID NIH HHS/ -- R01 CA154499/CA/NCI NIH HHS/ -- R01 CA154499-04/CA/NCI NIH HHS/ -- R37 AI039115/AI/NIAID NIH HHS/ -- R37 AI39115-17/AI/NIAID NIH HHS/ -- England -- Nature. 2014 Sep 25;513(7519):555-8. doi: 10.1038/nature13575.

    Fungal lipochitooligosaccharide symbiotic signals in arbuscular mycorrhiza (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-01-07
    Description: Arbuscular mycorrhiza (AM) is a root endosymbiosis between plants and glomeromycete fungi. It is the most widespread terrestrial plant symbiosis, improving plant uptake of water and mineral nutrients. Yet, despite its crucial role in land ecosystems, molecular mechanisms leading to its formation are just beginning to be unravelled. Recent evidence suggests that AM fungi produce diffusible symbiotic signals. Here we show that Glomus intraradices secretes symbiotic signals that are a mixture of sulphated and non-sulphated simple lipochitooligosaccharides (LCOs), which stimulate formation of AM in plant species of diverse families (Fabaceae, Asteraceae and Umbelliferae). In the legume Medicago truncatula these signals stimulate root growth and branching by the symbiotic DMI signalling pathway. These findings provide a better understanding of the evolution of signalling mechanisms involved in plant root endosymbioses and will greatly facilitate their molecular dissection. They also open the way to using these natural and very active molecules in agriculture.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maillet, Fabienne -- Poinsot, Verena -- Andre, Olivier -- Puech-Pages, Virginie -- Haouy, Alexandra -- Gueunier, Monique -- Cromer, Laurence -- Giraudet, Delphine -- Formey, Damien -- Niebel, Andreas -- Martinez, Eduardo Andres -- Driguez, Hugues -- Becard, Guillaume -- Denarie, Jean -- England -- Nature. 2011 Jan 6;469(7328):58-63. doi: 10.1038/nature09622.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire des Interactions Plantes-Microorganismes, UMR 441/2594 INRA-CNRS, B.P. 52627, F-31326 Castanet-Tolosan CEDEX, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21209659" target="_blank"〉PubMed〈/a〉

    A mitochondrial genome sequence of a hominin from Sima de los Huesos (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-12-07
    Description: Excavations of a complex of caves in the Sierra de Atapuerca in northern Spain have unearthed hominin fossils that range in age from the early Pleistocene to the Holocene. One of these sites, the 'Sima de los Huesos' ('pit of bones'), has yielded the world's largest assemblage of Middle Pleistocene hominin fossils, consisting of at least 28 individuals dated to over 300,000 years ago. The skeletal remains share a number of morphological features with fossils classified as Homo heidelbergensis and also display distinct Neanderthal-derived traits. Here we determine an almost complete mitochondrial genome sequence of a hominin from Sima de los Huesos and show that it is closely related to the lineage leading to mitochondrial genomes of Denisovans, an eastern Eurasian sister group to Neanderthals. Our results pave the way for DNA research on hominins from the Middle Pleistocene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, Matthias -- Fu, Qiaomei -- Aximu-Petri, Ayinuer -- Glocke, Isabelle -- Nickel, Birgit -- Arsuaga, Juan-Luis -- Martinez, Ignacio -- Gracia, Ana -- de Castro, Jose Maria Bermudez -- Carbonell, Eudald -- Paabo, Svante -- England -- Nature. 2014 Jan 16;505(7483):403-6. doi: 10.1038/nature12788.

    Structural basis for Ca2+ selectivity of a voltage-gated calcium channel (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-11-26
    Description: Voltage-gated calcium (CaV) channels catalyse rapid, highly selective influx of Ca(2+) into cells despite a 70-fold higher extracellular concentration of Na(+). How CaV channels solve this fundamental biophysical problem remains unclear. Here we report physiological and crystallographic analyses of a calcium selectivity filter constructed in the homotetrameric bacterial NaV channel NaVAb. Our results reveal interactions of hydrated Ca(2+) with two high-affinity Ca(2+)-binding sites followed by a third lower-affinity site that would coordinate Ca(2+) as it moves inward. At the selectivity filter entry, Site 1 is formed by four carboxyl side chains, which have a critical role in determining Ca(2+) selectivity. Four carboxyls plus four backbone carbonyls form Site 2, which is targeted by the blocking cations Cd(2+) and Mn(2+), with single occupancy. The lower-affinity Site 3 is formed by four backbone carbonyls alone, which mediate exit into the central cavity. This pore architecture suggests a conduction pathway involving transitions between two main states with one or two hydrated Ca(2+) ions bound in the selectivity filter and supports a 'knock-off' mechanism of ion permeation through a stepwise-binding process. The multi-ion selectivity filter of our CaVAb model establishes a structural framework for understanding the mechanisms of ion selectivity and conductance by vertebrate CaV channels.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3877713/" 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/PMC3877713/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tang, Lin -- Gamal El-Din, Tamer M -- Payandeh, Jian -- Martinez, Gilbert Q -- Heard, Teresa M -- Scheuer, Todd -- Zheng, Ning -- Catterall, William A -- R01 HL112808/HL/NHLBI NIH HHS/ -- R01 HL117896/HL/NHLBI NIH HHS/ -- R01 NS015751/NS/NINDS NIH HHS/ -- R01HL112808/HL/NHLBI NIH HHS/ -- R01NS015751/NS/NINDS NIH HHS/ -- T32 GM008268/GM/NIGMS NIH HHS/ -- T32GM008268/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Jan 2;505(7481):56-61. doi: 10.1038/nature12775.

    Crystal structure of a potassium ion transporter, TrkH (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-02-15
    Description: The TrkH/TrkG/KtrB proteins mediate K(+) uptake in bacteria and probably evolved from simple K(+) channels by multiple gene duplications or fusions. Here we present the crystal structure of a TrkH from Vibrio parahaemolyticus. TrkH is a homodimer, and each protomer contains an ion permeation pathway. A selectivity filter, similar in architecture to those of K(+) channels but significantly shorter, is lined by backbone and side-chain oxygen atoms. Functional studies showed that TrkH is selective for permeation of K(+) and Rb(+) over smaller ions such as Na(+) or Li(+). Immediately intracellular to the selectivity filter are an intramembrane loop and an arginine residue, both highly conserved, which constrict the permeation pathway. Substituting the arginine with an alanine significantly increases the rate of K(+) flux. These results reveal the molecular basis of K(+) selectivity and suggest a novel gating mechanism for this large and important family of membrane transport proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3077569/" 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/PMC3077569/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cao, Yu -- Jin, Xiangshu -- Huang, Hua -- Derebe, Mehabaw Getahun -- Levin, Elena J -- Kabaleeswaran, Venkataraman -- Pan, Yaping -- Punta, Marco -- Love, James -- Weng, Jun -- Quick, Matthias -- Ye, Sheng -- Kloss, Brian -- Bruni, Renato -- Martinez-Hackert, Erik -- Hendrickson, Wayne A -- Rost, Burkhard -- Javitch, Jonathan A -- Rajashankar, Kanagalaghatta R -- Jiang, Youxing -- Zhou, Ming -- DK088057/DK/NIDDK NIH HHS/ -- GM05026/GM/NIGMS NIH HHS/ -- GM05026-SUB0007/GM/NIGMS NIH HHS/ -- HL086392/HL/NHLBI NIH HHS/ -- K05 DA022413/DA/NIDA NIH HHS/ -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 DK088057/DK/NIDDK NIH HHS/ -- R01 DK088057-01/DK/NIDDK NIH HHS/ -- R01 HL086392/HL/NHLBI NIH HHS/ -- R01 HL086392-05/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Mar 17;471(7338):336-40. doi: 10.1038/nature09731.

    The genome of Tetranychus urticae reveals herbivorous pest adaptations (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-11-25
    Description: The spider mite Tetranychus urticae is a cosmopolitan agricultural pest with an extensive host plant range and an extreme record of pesticide resistance. Here we present the completely sequenced and annotated spider mite genome, representing the first complete chelicerate genome. At 90 megabases T. urticae has the smallest sequenced arthropod genome. Compared with other arthropods, the spider mite genome shows unique changes in the hormonal environment and organization of the Hox complex, and also reveals evolutionary innovation of silk production. We find strong signatures of polyphagy and detoxification in gene families associated with feeding on different hosts and in new gene families acquired by lateral gene transfer. Deep transcriptome analysis of mites feeding on different plants shows how this pest responds to a changing host environment. The T. urticae genome thus offers new insights into arthropod evolution and plant-herbivore interactions, and provides unique opportunities for developing novel plant protection strategies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grbic, Miodrag -- Van Leeuwen, Thomas -- Clark, Richard M -- Rombauts, Stephane -- Rouze, Pierre -- Grbic, Vojislava -- Osborne, Edward J -- Dermauw, Wannes -- Ngoc, Phuong Cao Thi -- Ortego, Felix -- Hernandez-Crespo, Pedro -- Diaz, Isabel -- Martinez, Manuel -- Navajas, Maria -- Sucena, Elio -- Magalhaes, Sara -- Nagy, Lisa -- Pace, Ryan M -- Djuranovic, Sergej -- Smagghe, Guy -- Iga, Masatoshi -- Christiaens, Olivier -- Veenstra, Jan A -- Ewer, John -- Villalobos, Rodrigo Mancilla -- Hutter, Jeffrey L -- Hudson, Stephen D -- Velez, Marisela -- Yi, Soojin V -- Zeng, Jia -- Pires-daSilva, Andre -- Roch, Fernando -- Cazaux, Marc -- Navarro, Marie -- Zhurov, Vladimir -- Acevedo, Gustavo -- Bjelica, Anica -- Fawcett, Jeffrey A -- Bonnet, Eric -- Martens, Cindy -- Baele, Guy -- Wissler, Lothar -- Sanchez-Rodriguez, Aminael -- Tirry, Luc -- Blais, Catherine -- Demeestere, Kristof -- Henz, Stefan R -- Gregory, T Ryan -- Mathieu, Johannes -- Verdon, Lou -- Farinelli, Laurent -- Schmutz, Jeremy -- Lindquist, Erika -- Feyereisen, Rene -- Van de Peer, Yves -- England -- Nature. 2011 Nov 23;479(7374):487-92. doi: 10.1038/nature10640.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, The University of Western Ontario, London N6A 5B7, Canada. mgrbic@uwo.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22113690" target="_blank"〉PubMed〈/a〉

    Genome sequence and analysis of the tuber crop potato (2011)

    Details
    Publication Date: 2011-07-12
    Description: Potato (Solanum tuberosum L.) is the world's most important non-grain food crop and is central to global food security. It is clonally propagated, highly heterozygous, autotetraploid, and suffers acute inbreeding depression. Here we use a homozygous doubled-monoploid potato clone to sequence and assemble 86% of the 844-megabase genome. We predict 39,031 protein-coding genes and present evidence for at least two genome duplication events indicative of a palaeopolyploid origin. As the first genome sequence of an asterid, the potato genome reveals 2,642 genes specific to this large angiosperm clade. We also sequenced a heterozygous diploid clone and show that gene presence/absence variants and other potentially deleterious mutations occur frequently and are a likely cause of inbreeding depression. Gene family expansion, tissue-specific expression and recruitment of genes to new pathways contributed to the evolution of tuber development. The potato genome sequence provides a platform for genetic improvement of this vital crop.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Potato Genome Sequencing Consortium -- Xu, Xun -- Pan, Shengkai -- Cheng, Shifeng -- Zhang, Bo -- Mu, Desheng -- Ni, Peixiang -- Zhang, Gengyun -- Yang, Shuang -- Li, Ruiqiang -- Wang, Jun -- Orjeda, Gisella -- Guzman, Frank -- Torres, Michael -- Lozano, Roberto -- Ponce, Olga -- Martinez, Diana -- De la Cruz, German -- Chakrabarti, S K -- Patil, Virupaksh U -- Skryabin, Konstantin G -- Kuznetsov, Boris B -- Ravin, Nikolai V -- Kolganova, Tatjana V -- Beletsky, Alexey V -- Mardanov, Andrei V -- Di Genova, Alex -- Bolser, Daniel M -- Martin, David M A -- Li, Guangcun -- Yang, Yu -- Kuang, Hanhui -- Hu, Qun -- Xiong, Xingyao -- Bishop, Gerard J -- Sagredo, Boris -- Mejia, Nilo -- Zagorski, Wlodzimierz -- Gromadka, Robert -- Gawor, Jan -- Szczesny, Pawel -- Huang, Sanwen -- Zhang, Zhonghua -- Liang, Chunbo -- He, Jun -- Li, Ying -- He, Ying -- Xu, Jianfei -- Zhang, Youjun -- Xie, Binyan -- Du, Yongchen -- Qu, Dongyu -- Bonierbale, Merideth -- Ghislain, Marc -- Herrera, Maria del Rosario -- Giuliano, Giovanni -- Pietrella, Marco -- Perrotta, Gaetano -- Facella, Paolo -- O'Brien, Kimberly -- Feingold, Sergio E -- Barreiro, Leandro E -- Massa, Gabriela A -- Diambra, Luis -- Whitty, Brett R -- Vaillancourt, Brieanne -- Lin, Haining -- Massa, Alicia N -- Geoffroy, Michael -- Lundback, Steven -- DellaPenna, Dean -- Buell, C Robin -- Sharma, Sanjeev Kumar -- Marshall, David F -- Waugh, Robbie -- Bryan, Glenn J -- Destefanis, Marialaura -- Nagy, Istvan -- Milbourne, Dan -- Thomson, Susan J -- Fiers, Mark -- Jacobs, Jeanne M E -- Nielsen, Kare L -- Sonderkaer, Mads -- Iovene, Marina -- Torres, Giovana A -- Jiang, Jiming -- Veilleux, Richard E -- Bachem, Christian W B -- de Boer, Jan -- Borm, Theo -- Kloosterman, Bjorn -- van Eck, Herman -- Datema, Erwin -- Hekkert, Bas te Lintel -- Goverse, Aska -- van Ham, Roeland C H J -- Visser, Richard G F -- BB/F012640/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F012640/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- WT 083481/Wellcome Trust/United Kingdom -- England -- Nature. 2011 Jul 10;475(7355):189-95. doi: 10.1038/nature10158.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉BGI-Shenzhen, Chinese Ministry of Agricultural, Key Lab of Genomics, Beishan Industrial Zone, Yantian District, Shenzhen 518083, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21743474" target="_blank"〉PubMed〈/a〉

    Description: Gorillas are humans' closest living relatives after chimpanzees, and are of comparable importance for the study of human origins and evolution. Here we present the assembly and analysis of a genome sequence for the western lowland gorilla, and compare the whole genomes of all extant great ape genera. We propose a synthesis of genetic and fossil evidence consistent with placing the human-chimpanzee and human-chimpanzee-gorilla speciation events at approximately 6 and 10 million years ago. In 30% of the genome, gorilla is closer to human or chimpanzee than the latter are to each other; this is rarer around coding genes, indicating pervasive selection throughout great ape evolution, and has functional consequences in gene expression. A comparison of protein coding genes reveals approximately 500 genes showing accelerated evolution on each of the gorilla, human and chimpanzee lineages, and evidence for parallel acceleration, particularly of genes involved in hearing. We also compare the western and eastern gorilla species, estimating an average sequence divergence time 1.75 million years ago, but with evidence for more recent genetic exchange and a population bottleneck in the eastern species. The use of the genome sequence in these and future analyses will promote a deeper understanding of great ape biology and evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3303130/" 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/PMC3303130/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scally, Aylwyn -- Dutheil, Julien Y -- Hillier, LaDeana W -- Jordan, Gregory E -- Goodhead, Ian -- Herrero, Javier -- Hobolth, Asger -- Lappalainen, Tuuli -- Mailund, Thomas -- Marques-Bonet, Tomas -- McCarthy, Shane -- Montgomery, Stephen H -- Schwalie, Petra C -- Tang, Y Amy -- Ward, Michelle C -- Xue, Yali -- Yngvadottir, Bryndis -- Alkan, Can -- Andersen, Lars N -- Ayub, Qasim -- Ball, Edward V -- Beal, Kathryn -- Bradley, Brenda J -- Chen, Yuan -- Clee, Chris M -- Fitzgerald, Stephen -- Graves, Tina A -- Gu, Yong -- Heath, Paul -- Heger, Andreas -- Karakoc, Emre -- Kolb-Kokocinski, Anja -- Laird, Gavin K -- Lunter, Gerton -- Meader, Stephen -- Mort, Matthew -- Mullikin, James C -- Munch, Kasper -- O'Connor, Timothy D -- Phillips, Andrew D -- Prado-Martinez, Javier -- Rogers, Anthony S -- Sajjadian, Saba -- Schmidt, Dominic -- Shaw, Katy -- Simpson, Jared T -- Stenson, Peter D -- Turner, Daniel J -- Vigilant, Linda -- Vilella, Albert J -- Whitener, Weldon -- Zhu, Baoli -- Cooper, David N -- de Jong, Pieter -- Dermitzakis, Emmanouil T -- Eichler, Evan E -- Flicek, Paul -- Goldman, Nick -- Mundy, Nicholas I -- Ning, Zemin -- Odom, Duncan T -- Ponting, Chris P -- Quail, Michael A -- Ryder, Oliver A -- Searle, Stephen M -- Warren, Wesley C -- Wilson, Richard K -- Schierup, Mikkel H -- Rogers, Jane -- Tyler-Smith, Chris -- Durbin, Richard -- 062023/Wellcome Trust/United Kingdom -- 075491/Z/04/Wellcome Trust/United Kingdom -- 077009/Wellcome Trust/United Kingdom -- 077192/Wellcome Trust/United Kingdom -- 077198/Wellcome Trust/United Kingdom -- 089066/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- 095908/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- G0501331/Medical Research Council/United Kingdom -- G0701805/Medical Research Council/United Kingdom -- HG002385/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- WT062023/Wellcome Trust/United Kingdom -- WT077009/Wellcome Trust/United Kingdom -- WT077192/Wellcome Trust/United Kingdom -- WT077198/Wellcome Trust/United Kingdom -- WT089066/Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- England -- Nature. 2012 Mar 7;483(7388):169-75. doi: 10.1038/nature10842.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton CB10 1SA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22398555" target="_blank"〉PubMed〈/a〉

    A novel multiple-stage antimalarial agent that inhibits protein synthesis (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-06-19
    Description: There is an urgent need for new drugs to treat malaria, with broad therapeutic potential and novel modes of action, to widen the scope of treatment and to overcome emerging drug resistance. Here we describe the discovery of DDD107498, a compound with a potent and novel spectrum of antimalarial activity against multiple life-cycle stages of the Plasmodium parasite, with good pharmacokinetic properties and an acceptable safety profile. DDD107498 demonstrates potential to address a variety of clinical needs, including single-dose treatment, transmission blocking and chemoprotection. DDD107498 was developed from a screening programme against blood-stage malaria parasites; its molecular target has been identified as translation elongation factor 2 (eEF2), which is responsible for the GTP-dependent translocation of the ribosome along messenger RNA, and is essential for protein synthesis. This discovery of eEF2 as a viable antimalarial drug target opens up new possibilities for drug discovery.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4700930/" 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/PMC4700930/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baragana, Beatriz -- Hallyburton, Irene -- Lee, Marcus C S -- Norcross, Neil R -- Grimaldi, Raffaella -- Otto, Thomas D -- Proto, William R -- Blagborough, Andrew M -- Meister, Stephan -- Wirjanata, Grennady -- Ruecker, Andrea -- Upton, Leanna M -- Abraham, Tara S -- Almeida, Mariana J -- Pradhan, Anupam -- Porzelle, Achim -- Martinez, Maria Santos -- Bolscher, Judith M -- Woodland, Andrew -- Norval, Suzanne -- Zuccotto, Fabio -- Thomas, John -- Simeons, Frederick -- Stojanovski, Laste -- Osuna-Cabello, Maria -- Brock, Paddy M -- Churcher, Tom S -- Sala, Katarzyna A -- Zakutansky, Sara E -- Jimenez-Diaz, Maria Belen -- Sanz, Laura Maria -- Riley, Jennifer -- Basak, Rajshekhar -- Campbell, Michael -- Avery, Vicky M -- Sauerwein, Robert W -- Dechering, Koen J -- Noviyanti, Rintis -- Campo, Brice -- Frearson, Julie A -- Angulo-Barturen, Inigo -- Ferrer-Bazaga, Santiago -- Gamo, Francisco Javier -- Wyatt, Paul G -- Leroy, Didier -- Siegl, Peter -- Delves, Michael J -- Kyle, Dennis E -- Wittlin, Sergio -- Marfurt, Jutta -- Price, Ric N -- Sinden, Robert E -- Winzeler, Elizabeth A -- Charman, Susan A -- Bebrevska, Lidiya -- Gray, David W -- Campbell, Simon -- Fairlamb, Alan H -- Willis, Paul A -- Rayner, Julian C -- Fidock, David A -- Read, Kevin D -- Gilbert, Ian H -- 079838/Wellcome Trust/United Kingdom -- 091625/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- 100476/Wellcome Trust/United Kingdom -- R01 AI090141/AI/NIAID NIH HHS/ -- R01 AI103058/AI/NIAID NIH HHS/ -- England -- Nature. 2015 Jun 18;522(7556):315-20. doi: 10.1038/nature14451.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Drug Discovery Unit, Division of Biological Chemistry and Drug Discovery, College of Life Sciences, University of Dundee, Dundee DD1 5EH, UK. ; Department of Microbiology and Immunology, Columbia University College of Physicians and Surgeons, New York, New York 10032, USA. ; Malaria Programme, Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Cambridge CB10 1SA, UK. ; Department of Life Sciences, Imperial College, London SW7 2AZ, UK. ; University of California, San Diego, School of Medicine, 9500 Gilman Drive 0760, La Jolla, California 92093, USA. ; Global Health and Tropical Medicine Division, Menzies School of Health Research, Charles Darwin University, PO Box 41096, Casuarina, Darwin, Northern Territory 0811, Australia. ; Department of Global Health, College of Public Health University of South Florida, 3720 Spectrum Boulevard, Suite 304, Tampa, Florida 33612, USA. ; GlaxoSmithKline, Tres Cantos Medicines Development Campus-Diseases of the Developing World, Severo Ochoa 2, Tres Cantos 28760, Madrid, Spain. ; TropIQ Health Sciences, Geert Grooteplein 28, Huispost 268, 6525 GA Nijmegen, The Netherlands. ; Centre for Drug Candidate Optimisation, Monash University, 381 Royal Parade, Parkville, Victoria 3052, Australia. ; Eskitis Institute, Brisbane Innovation Park, Nathan Campus, Griffith University, Queensland 4111, Australia. ; Malaria Pathogenesis Laboratory, Eijkman Institute for Molecular Biology, Jalan Diponegoro 69, 10430 Jakarta, Indonesia. ; Medicines for Malaria Venture, PO Box 1826, 20 route de Pre-Bois, 1215 Geneva 15, Switzerland. ; Swiss Tropical and Public Health Institute, Socinstrasse 57, 4051 Basel, Switzerland. ; 1] Global Health and Tropical Medicine Division, Menzies School of Health Research, Charles Darwin University, PO Box 41096, Casuarina, Darwin, Northern Territory 0811, Australia [2] Centre for Tropical Medicine and Global Health, Nuffield Department of Medicine, University of Oxford, Oxford OX3 7LJ, UK. ; 1] Department of Microbiology and Immunology, Columbia University College of Physicians and Surgeons, New York, New York 10032, USA [2] Division of Infectious Diseases, Department of Medicine, Columbia University College of Physicians and Surgeons, New York, New York 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26085270" target="_blank"〉PubMed〈/a〉

    Community genomics among stratified microbial assemblages in the ocean's interior (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-01-28
    Description: Microbial life predominates in the ocean, yet little is known about its genomic variability, especially along the depth continuum. We report here genomic analyses of planktonic microbial communities in the North Pacific Subtropical Gyre, from the ocean's surface to near-sea floor depths. Sequence variation in microbial community genes reflected vertical zonation of taxonomic groups, functional gene repertoires, and metabolic potential. The distributional patterns of microbial genes suggested depth-variable community trends in carbon and energy metabolism, attachment and motility, gene mobility, and host-viral interactions. Comparative genomic analyses of stratified microbial communities have the potential to provide significant insight into higher-order community organization and dynamics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DeLong, Edward F -- Preston, Christina M -- Mincer, Tracy -- Rich, Virginia -- Hallam, Steven J -- Frigaard, Niels-Ulrik -- Martinez, Asuncion -- Sullivan, Matthew B -- Edwards, Robert -- Brito, Beltran Rodriguez -- Chisholm, Sallie W -- Karl, David M -- New York, N.Y. -- Science. 2006 Jan 27;311(5760):496-503.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts Institute of Technology, Cambridge, MA 02139, USA. delong@mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16439655" target="_blank"〉PubMed〈/a〉
