    Negative plant-soil feedback predicts tree-species relative abundance in a tropical forest (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-06-29
    Description: The accumulation of species-specific enemies around adults is hypothesized to maintain plant diversity by limiting the recruitment of conspecific seedlings relative to heterospecific seedlings. Although previous studies in forested ecosystems have documented patterns consistent with the process of negative feedback, these studies are unable to address which classes of enemies (for example, pathogens, invertebrates, mammals) exhibit species-specific effects strong enough to generate negative feedback, and whether negative feedback at the level of the individual tree is sufficient to influence community-wide forest composition. Here we use fully reciprocal shade-house and field experiments to test whether the performance of conspecific tree seedlings (relative to heterospecific seedlings) is reduced when grown in the presence of enemies associated with adult trees. Both experiments provide strong evidence for negative plant-soil feedback mediated by soil biota. In contrast, above-ground enemies (mammals, foliar herbivores and foliar pathogens) contributed little to negative feedback observed in the field. In both experiments, we found that tree species that showed stronger negative feedback were less common as adults in the forest community, indicating that susceptibility to soil biota may determine species relative abundance in these tropical forests. Finally, our simulation models confirm that the strength of local negative feedback that we measured is sufficient to produce the observed community-wide patterns in tree-species relative abundance. Our findings indicate that plant-soil feedback is an important mechanism that can maintain species diversity and explain patterns of tree-species relative abundance in tropical forests.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mangan, Scott A -- Schnitzer, Stefan A -- Herre, Edward A -- Mack, Keenan M L -- Valencia, Mariana C -- Sanchez, Evelyn I -- Bever, James D -- R01 GM092660/GM/NIGMS NIH HHS/ -- England -- Nature. 2010 Aug 5;466(7307):752-5. doi: 10.1038/nature09273.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Wisconsin-Milwaukee, Wisconsin 53201, USA. smangan37@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20581819" target="_blank"〉PubMed〈/a〉

    A methyl transferase links the circadian clock to the regulation of alternative splicing (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-10-22
    Description: Circadian rhythms allow organisms to time biological processes to the most appropriate phases of the day-night cycle. Post-transcriptional regulation is emerging as an important component of circadian networks, but the molecular mechanisms linking the circadian clock to the control of RNA processing are largely unknown. Here we show that PROTEIN ARGININE METHYL TRANSFERASE 5 (PRMT5), which transfers methyl groups to arginine residues present in histones and Sm spliceosomal proteins, links the circadian clock to the control of alternative splicing in plants. Mutations in PRMT5 impair several circadian rhythms in Arabidopsis thaliana and this phenotype is caused, at least in part, by a strong alteration in alternative splicing of the core-clock gene PSEUDO RESPONSE REGULATOR 9 (PRR9). Furthermore, genome-wide studies show that PRMT5 contributes to the regulation of many pre-messenger-RNA splicing events, probably by modulating 5'-splice-site recognition. PRMT5 expression shows daily and circadian oscillations, and this contributes to the mediation of the circadian regulation of expression and alternative splicing of a subset of genes. Circadian rhythms in locomotor activity are also disrupted in dart5-1, a mutant affected in the Drosophila melanogaster PRMT5 homologue, and this is associated with alterations in splicing of the core-clock gene period and several clock-associated genes. Our results demonstrate a key role for PRMT5 in the regulation of alternative splicing and indicate that the interplay between the circadian clock and the regulation of alternative splicing by PRMT5 constitutes a common mechanism that helps organisms to synchronize physiological processes with daily changes in environmental conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sanchez, Sabrina E -- Petrillo, Ezequiel -- Beckwith, Esteban J -- Zhang, Xu -- Rugnone, Matias L -- Hernando, C Esteban -- Cuevas, Juan C -- Godoy Herz, Micaela A -- Depetris-Chauvin, Ana -- Simpson, Craig G -- Brown, John W S -- Cerdan, Pablo D -- Borevitz, Justin O -- Mas, Paloma -- Ceriani, M Fernanda -- Kornblihtt, Alberto R -- Yanovsky, Marcelo J -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Nov 4;468(7320):112-6. doi: 10.1038/nature09470.

    Loss of fish actinotrichia proteins and the fin-to-limb transition (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-06-25
    Description: The early development of teleost paired fins is strikingly similar to that of tetrapod limb buds and is controlled by similar mechanisms. One early morphological divergence between pectoral fins and limbs is in the fate of the apical ectodermal ridge (AER), the distal epidermis that rims the bud. Whereas the AER of tetrapods regresses after specification of the skeletal progenitors, the AER of teleost fishes forms a fold that elongates. Formation of the fin fold is accompanied by the synthesis of two rows of rigid, unmineralized fibrils called actinotrichia, which keep the fold straight and guide the migration of mesenchymal cells within the fold. The actinotrichia are made of elastoidin, the components of which, apart from collagen, are unknown. Here we show that two zebrafish proteins, which we name actinodin 1 and 2 (And1 and And2), are essential structural components of elastoidin. The presence of actinodin sequences in several teleost fishes and in the elephant shark (Callorhinchus milii, which occupies a basal phylogenetic position), but not in tetrapods, suggests that these genes have been lost during tetrapod species evolution. Double gene knockdown of and1 and and2 in zebrafish embryos results in the absence of actinotrichia and impaired fin folds. Gene expression profiles in embryos lacking and1 and and2 function are consistent with pectoral fin truncation and may offer a potential explanation for the polydactyly observed in early tetrapod fossils. We propose that the loss of both actinodins and actinotrichia during evolution may have led to the loss of lepidotrichia and may have contributed to the fin-to-limb transition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Jing -- Wagh, Purva -- Guay, Danielle -- Sanchez-Pulido, Luis -- Padhi, Bhaja K -- Korzh, Vladimir -- Andrade-Navarro, Miguel A -- Akimenko, Marie-Andree -- MC_U137761446/Medical Research Council/United Kingdom -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2010 Jul 8;466(7303):234-7. doi: 10.1038/nature09137.

    Stage-specific sensitivity to p53 restoration during lung cancer progression (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-11-26
    Description: Tumorigenesis is a multistep process that results from the sequential accumulation of mutations in key oncogene and tumour suppressor pathways. Personalized cancer therapy that is based on targeting these underlying genetic abnormalities presupposes that sustained inactivation of tumour suppressors and activation of oncogenes is essential in advanced cancers. Mutations in the p53 tumour-suppressor pathway are common in human cancer and significant efforts towards pharmaceutical reactivation of defective p53 pathways are underway. Here we show that restoration of p53 in established murine lung tumours leads to significant but incomplete tumour cell loss specifically in malignant adenocarcinomas, but not in adenomas. We define amplification of MAPK signalling as a critical determinant of malignant progression and also a stimulator of Arf tumour-suppressor expression. The response to p53 restoration in this context is critically dependent on the expression of Arf. We propose that p53 not only limits malignant progression by suppressing the acquisition of alterations that lead to tumour progression, but also, in the context of p53 restoration, responds to increased oncogenic signalling to mediate tumour regression. Our observations also underscore that the p53 pathway is not engaged by low levels of oncogene activity that are sufficient for early stages of lung tumour development. These data suggest that restoration of pathways important in tumour progression, as opposed to initiation, may lead to incomplete tumour regression due to the stage-heterogeneity of tumour cell populations.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3003305/" 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/PMC3003305/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feldser, David M -- Kostova, Kamena K -- Winslow, Monte M -- Taylor, Sarah E -- Cashman, Chris -- Whittaker, Charles A -- Sanchez-Rivera, Francisco J -- Resnick, Rebecca -- Bronson, Roderick -- Hemann, Michael T -- Jacks, Tyler -- P30 CA014051/CA/NCI NIH HHS/ -- P30 CA014051-37/CA/NCI NIH HHS/ -- P30 CA014051-38/CA/NCI NIH HHS/ -- P30 CA014051-39/CA/NCI NIH HHS/ -- P30 CA014051-40/CA/NCI NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Nov 25;468(7323):572-5. doi: 10.1038/nature09535.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Koch Institute for Integrative Cancer Research, Department of Biology, and Howard Hughes Medical Institute, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, Massachusetts 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21107428" target="_blank"〉PubMed〈/a〉

    Oxidant stress evoked by pacemaking in dopaminergic neurons is attenuated by DJ-1 (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-11-12
    Description: Parkinson's disease is a pervasive, ageing-related neurodegenerative disease the cardinal motor symptoms of which reflect the loss of a small group of neurons, the dopaminergic neurons in the substantia nigra pars compacta (SNc). Mitochondrial oxidant stress is widely viewed as being responsible for this loss, but why these particular neurons should be stressed is a mystery. Here we show, using transgenic mice that expressed a redox-sensitive variant of green fluorescent protein targeted to the mitochondrial matrix, that the engagement of plasma membrane L-type calcium channels during normal autonomous pacemaking created an oxidant stress that was specific to vulnerable SNc dopaminergic neurons. The oxidant stress engaged defences that induced transient, mild mitochondrial depolarization or uncoupling. The mild uncoupling was not affected by deletion of cyclophilin D, which is a component of the permeability transition pore, but was attenuated by genipin and purine nucleotides, which are antagonists of cloned uncoupling proteins. Knocking out DJ-1 (also known as PARK7 in humans and Park7 in mice), which is a gene associated with an early-onset form of Parkinson's disease, downregulated the expression of two uncoupling proteins (UCP4 (SLC25A27) and UCP5 (SLC25A14)), compromised calcium-induced uncoupling and increased oxidation of matrix proteins specifically in SNc dopaminergic neurons. Because drugs approved for human use can antagonize calcium entry through L-type channels, these results point to a novel neuroprotective strategy for both idiopathic and familial forms of Parkinson's disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4465557/" 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/PMC4465557/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guzman, Jaime N -- Sanchez-Padilla, Javier -- Wokosin, David -- Kondapalli, Jyothisri -- Ilijic, Ema -- Schumacker, Paul T -- Surmeier, D James -- HL35440/HL/NHLBI NIH HHS/ -- K12GM088020/GM/NIGMS NIH HHS/ -- NS 054850/NS/NINDS NIH HHS/ -- NS047085/NS/NINDS NIH HHS/ -- P30 NS054850/NS/NINDS NIH HHS/ -- P50 NS047085/NS/NINDS NIH HHS/ -- R01 HL035440/HL/NHLBI NIH HHS/ -- R21 RR025355/RR/NCRR NIH HHS/ -- RR025355/RR/NCRR NIH HHS/ -- England -- Nature. 2010 Dec 2;468(7324):696-700. doi: 10.1038/nature09536.

    Deep winds beneath Saturn's upper clouds from a seasonal long-lived planetary-scale storm (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-07-08
    Description: Convective storms occur regularly in Saturn's atmosphere. Huge storms known as Great White Spots, which are ten times larger than the regular storms, are rarer and occur about once per Saturnian year (29.5 Earth years). Current models propose that the outbreak of a Great White Spot is due to moist convection induced by water. However, the generation of the global disturbance and its effect on Saturn's permanent winds have hitherto been unconstrained by data, because there was insufficient spatial resolution and temporal sampling to infer the dynamics of Saturn's weather layer (the layer in the troposphere where the cloud forms). Theoretically, it has been suggested that this phenomenon is seasonally controlled. Here we report observations of a storm at northern latitudes in the peak of a weak westward jet during the beginning of northern springtime, in accord with the seasonal cycle but earlier than expected. The storm head moved faster than the jet, was active during the two-month observation period, and triggered a planetary-scale disturbance that circled Saturn but did not significantly alter the ambient zonal winds. Numerical simulations of the phenomenon show that, as on Jupiter, Saturn's winds extend without decay deep down into the weather layer, at least to the water-cloud base at pressures of 10-12 bar, which is much deeper than solar radiation penetrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sanchez-Lavega, A -- del Rio-Gaztelurrutia, T -- Hueso, R -- Gomez-Forrellad, J M -- Sanz-Requena, J F -- Legarreta, J -- Garcia-Melendo, E -- Colas, F -- Lecacheux, J -- Fletcher, L N -- Barrado-Navascues, D -- Parker, D -- International Outer Planet Watch Team -- England -- Nature. 2011 Jul 6;475(7354):71-4. doi: 10.1038/nature10203.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departamento de Fisica Aplicada I, Escuela Tecnica Superior de Ingenieria, Universidad del Pais Vasco, Alameda Urquijo s/n, 48013 Bilbao, Spain. agustin.sanchez@ehu.es〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21734704" target="_blank"〉PubMed〈/a〉

    Sequence analysis of mutations and translocations across breast cancer subtypes (2012)
    Nature Publishing Group (NPG)

    Publication Date: 2012-06-23
    Description: Breast carcinoma is the leading cause of cancer-related mortality in women worldwide, with an estimated 1.38 million new cases and 458,000 deaths in 2008 alone. This malignancy represents a heterogeneous group of tumours with characteristic molecular features, prognosis and responses to available therapy. Recurrent somatic alterations in breast cancer have been described, including mutations and copy number alterations, notably ERBB2 amplifications, the first successful therapy target defined by a genomic aberration. Previous DNA sequencing studies of breast cancer genomes have revealed additional candidate mutations and gene rearrangements. Here we report the whole-exome sequences of DNA from 103 human breast cancers of diverse subtypes from patients in Mexico and Vietnam compared to matched-normal DNA, together with whole-genome sequences of 22 breast cancer/normal pairs. Beyond confirming recurrent somatic mutations in PIK3CA, TP53, AKT1, GATA3 and MAP3K1, we discovered recurrent mutations in the CBFB transcription factor gene and deletions of its partner RUNX1. Furthermore, we have identified a recurrent MAGI3-AKT3 fusion enriched in triple-negative breast cancer lacking oestrogen and progesterone receptors and ERBB2 expression. The MAGI3-AKT3 fusion leads to constitutive activation of AKT kinase, which is abolished by treatment with an ATP-competitive AKT small-molecule inhibitor.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4148686/" 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/PMC4148686/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banerji, Shantanu -- Cibulskis, Kristian -- Rangel-Escareno, Claudia -- Brown, Kristin K -- Carter, Scott L -- Frederick, Abbie M -- Lawrence, Michael S -- Sivachenko, Andrey Y -- Sougnez, Carrie -- Zou, Lihua -- Cortes, Maria L -- Fernandez-Lopez, Juan C -- Peng, Shouyong -- Ardlie, Kristin G -- Auclair, Daniel -- Bautista-Pina, Veronica -- Duke, Fujiko -- Francis, Joshua -- Jung, Joonil -- Maffuz-Aziz, Antonio -- Onofrio, Robert C -- Parkin, Melissa -- Pho, Nam H -- Quintanar-Jurado, Valeria -- Ramos, Alex H -- Rebollar-Vega, Rosa -- Rodriguez-Cuevas, Sergio -- Romero-Cordoba, Sandra L -- Schumacher, Steven E -- Stransky, Nicolas -- Thompson, Kristin M -- Uribe-Figueroa, Laura -- Baselga, Jose -- Beroukhim, Rameen -- Polyak, Kornelia -- Sgroi, Dennis C -- Richardson, Andrea L -- Jimenez-Sanchez, Gerardo -- Lander, Eric S -- Gabriel, Stacey B -- Garraway, Levi A -- Golub, Todd R -- Melendez-Zajgla, Jorge -- Toker, Alex -- Getz, Gad -- Hidalgo-Miranda, Alfredo -- Meyerson, Matthew -- CA089393/CA/NCI NIH HHS/ -- CA122099/CA/NCI NIH HHS/ -- R01 CA122099/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Jun 20;486(7403):405-9. doi: 10.1038/nature11154.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Broad Institute of MIT and Harvard, Cambridge, Massachusetts 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22722202" target="_blank"〉PubMed〈/a〉

    Description: Tapeworms (Cestoda) cause neglected diseases that can be fatal and are difficult to treat, owing to inefficient drugs. Here we present an analysis of tapeworm genome sequences using the human-infective species Echinococcus multilocularis, E. granulosus, Taenia solium and the laboratory model Hymenolepis microstoma as examples. The 115- to 141-megabase genomes offer insights into the evolution of parasitism. Synteny is maintained with distantly related blood flukes but we find extreme losses of genes and pathways that are ubiquitous in other animals, including 34 homeobox families and several determinants of stem cell fate. Tapeworms have specialized detoxification pathways, metabolism that is finely tuned to rely on nutrients scavenged from their hosts, and species-specific expansions of non-canonical heat shock proteins and families of known antigens. We identify new potential drug targets, including some on which existing pharmaceuticals may act. The genomes provide a rich resource to underpin the development of urgently needed treatments and control.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3964345/" 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/PMC3964345/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsai, Isheng J -- Zarowiecki, Magdalena -- Holroyd, Nancy -- Garciarrubio, Alejandro -- Sanchez-Flores, Alejandro -- Brooks, Karen L -- Tracey, Alan -- Bobes, Raul J -- Fragoso, Gladis -- Sciutto, Edda -- Aslett, Martin -- Beasley, Helen -- Bennett, Hayley M -- Cai, Jianping -- Camicia, Federico -- Clark, Richard -- Cucher, Marcela -- De Silva, Nishadi -- Day, Tim A -- Deplazes, Peter -- Estrada, Karel -- Fernandez, Cecilia -- Holland, Peter W H -- Hou, Junling -- Hu, Songnian -- Huckvale, Thomas -- Hung, Stacy S -- Kamenetzky, Laura -- Keane, Jacqueline A -- Kiss, Ferenc -- Koziol, Uriel -- Lambert, Olivia -- Liu, Kan -- Luo, Xuenong -- Luo, Yingfeng -- Macchiaroli, Natalia -- Nichol, Sarah -- Paps, Jordi -- Parkinson, John -- Pouchkina-Stantcheva, Natasha -- Riddiford, Nick -- Rosenzvit, Mara -- Salinas, Gustavo -- Wasmuth, James D -- Zamanian, Mostafa -- Zheng, Yadong -- Taenia solium Genome Consortium -- Cai, Xuepeng -- Soberon, Xavier -- Olson, Peter D -- Laclette, Juan P -- Brehm, Klaus -- Berriman, Matthew -- 085775/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- BBG0038151/Biotechnology and Biological Sciences Research Council/United Kingdom -- MOP#84556/Canadian Institutes of Health Research/Canada -- TW008588/TW/FIC NIH HHS/ -- England -- Nature. 2013 Apr 4;496(7443):57-63. doi: 10.1038/nature12031.
