    The impact generated on Sea Turtles by Fisheries in the Southwestern Atlantic Ocean (2009)
    WWF Programa Marino para Latinoamérica y el Caribe
    Details
    Publication Date: 2021-05-19
    Description: This document, which is directed at the fishing sector, researchers, conservationists and fishery administrators, was developed by researchers who are members of the Specialists Group for Marine Turtle Research and conservation in the Southwestern Atlantic Ocean (SWA) in response to the urgent need to evaluate the impact generated on sea turtles by fisheries. Historically, sea turtle conservation efforts have focused almost exclusively on the protection of nesting beaches. Nevertheless, over the last decade, research has proved incidental mortality as a result of fishing activities to be one of the greatest threats to these animals. This type of interaction is not only problematic for turtles, but also generates financial losses for fishermen and businesses. In spite of the efforts that are currently underway, researchers still do not have a detailed understanding of the impact that bycatch produces on sea turtle populations in the SWA. We have a long way to go before its effects can be minimized. Further research is needed regarding the biology and ecology of the various turtle species as well as the effective application of mitigation measures. The life cycles of sea turtles are long and complex. Turtles occupy various ecosystems (nesting beaches, coastal, neritic and oceanic zones, as well as pelagic and demersal areas) throughout their lifetimes, transcending various Exclusive Economic Zones and International Waters. The five species that inhabit the SWA region perform vast feeding and reproductive migrations, traveling through areas where many different fishing fleets operate. Therefore, sea turtles in the SWA interact with virtually all fisheries. These circumstances make it necessary to carry out biological, fishing related and conservation studies on a regional level. The efficiency of the existing international and national legal instruments has yet to be determined, in terms of their effectiveness in protecting sea turtles. In some cases, legislation that is specifically related to the interaction between fisheries and turtles does exist, such as those laws requiring the mandatory use of turtle excluding devices (TEDs). There are also explicit bans on sea turtle capture. Nevertheless, none of these regulations prevent sea turtle bycatch. Although some regional legal instruments are needed, these and the existing legislation will only be effective if they are accompanied by a broader range of permanent education and control measures, to achieve the commitment of all the parties involved. The ecosystem approach is gaining popularity among fishery administration organizations. Research and conservation efforts should also be moving in that direction. A regional and international effort is required in order to compile information regarding the bycatch produced by the various types of fisheries and fleets operating in the area. The enormous increase in fishing pressure that these fleets are exerting in this area has not been accompanied by an increase in information regarding the bycatch of species that have no commercial value. Pelagic longlining is one of the fishing methods, which must be most closely monitored, due to the high levels of bycatch that it produces, as well its ample distribution throughout the region, and the high level of fishing effort that it accounts for. Coastal trawlers and gillnetters must also be considered critical players, because they too produce a large rate of bycatch. These are the three types of fisheries that are most broadly distributed throughout the region, accounting for the majority of the fishing effort. Most of the institutions that work toward sea turtle conservation in the area have only begun to address the issue of bycatch over the last decade. This timeframe is reflected in the scope and quantity of the available publications, as well as the progress of activities directed at mitigating this problem. All of the institutions that have been mentioned in this report have made the gathering of information regarding interaction between sea turtles and fisheries one of their top priorities. Some institutions are even developing working programs for monitoring fisheries and testing mitigation measures. Many of these institutions have managed to develop adequate relationships with fishermen, ship owners and administrators. Nevertheless, limited access to funding is an obstacle to the development and testing of mitigation measures. The SWA network, which is a very valuable instrument that was created in 2003, has allowed the region’s institutions and researchers to exchange information and share their experience, in addition to lending each other support in carrying out joint activities, thus strengthening sea turtle conservation efforts. The capacity demonstrated so far by the region’s researchers and institutions, testifies to their ability to continue to make progress in knowledge generation and tests of bycatch mitigation measures.

    El impacto generado por las pesquerías en las tortugas marinas en el Océano Atlántico Sud Occidental (2009)
    WWF Programa Marino para Latinoamérica y el Caribe
    Details
    Publication Date: 2021-05-19
    Description: Este documento, dirigido al sector pesquero, investigadores, conservacionistas y administradores de las pesquerías, surge como respuesta de investigadores pertenecientes al Grupo de Especialistas en Investigación y Conservación de Tortugas Marinas en el Atlántico Sud Occidental (ASO) a la urgente necesidad de evaluar el impacto de las pesquerías sobre las tortugas marinas. Históricamente, los esfuerzos referidos a la conservación de las tortugas marinas se han dirigido casi exclusivamente a proteger las playas de anidación. Sin embargo en la última década se ha podido comprobar que una de las mayores amenazas es la mortalidad incidental causada por las pesquerías. Esta interacción no implica únicamente un problema para las tortugas, sino que también genera pérdidas económicas para los pescadores y las empresas.

    Un estudio de histamina en Dorado MAHI-MAHI Coryphaena hippurus y su relación con la calidad de producto de la pesca ecuatoriana (2009)
    INP (Ecuador)
    Details
    Publication Date: 2021-05-19
    Description: El presente trabajo llama la atención a las recientes epidemias de intoxicación histamínicas reportadas en los Estados Unidos, debido al consumo del dorado (Coryphaena hippurus) o Mahi-Mah, contaminado. Esto dió como resultado la prohición de las importaciones de esta especie, proveniente de varios países entre ellos el Ecuador, y siendo el dorado una especie de relativa importancia económica en este país, dicha prohibición ha preocupado al sector pesquero. Los estudios llevados a cabo muestran claramente la susceptibilidad de esta especie a desarrollar histamina. Esto se debe principalmente a la temperatura a la que está expuesta, pues la demora antes de enhielar el pescado es la etapa crítica. Los resultados muestran un aumento exponencial de los niveles de histamina, en ciertos casos después de tan solo 9 horas de almacenaje a temperaturas ambientales entre 25-30°C. Los niveles de histamina en pescado muestreado en el mercado local fueron tan altos como 250 mg/100g de muestra. Se demuestra que el problema se debe fundamentalmente al mal manejo de la captura por parte de la flota artesanal, y la subsecuente falta de infraestructura adecuada para conservarla, es decir, no se enfría el pescado. Sin embargo, el estudio muestra que una reducción de la temperatura del pescado de solo 15° menos, podría dar como resultado un producto de mayor calidad. En el presente trabajo se hacen recomendaciones para establecer un nivel máximo permitido para la exportación de 10 mg%, y se comparan dos métodos rápidos de análisis.

    Un estudio de la factibilidad del uso de trampas para peces como un nuevo método de pesca en las Islas Galápagos (2009)
    INP (Ecuador)
    Details
    Publication Date: 2021-05-19
    Description: 153 experimental sets were made with stackable Antillean fish traps in depths of 5 to 30 m in the waters around the Galápagos Island (Ecuador), between Octobre and April 1983. 1,885 fish were caught of 18 species mainly of the families Pomadasyidae, Acanthuridae, Sparidae and Serranidae. The mean catch rate was 5,5 Kg per lift or 0,4 Kg.h-1, and the mean weight of the fish caught was 0,45 Kg. The optimum set duration was found to be between 2 and 18 hours (possibly indicating a high rate of escape). This study took place during the period of the ”El Niño”, when catches of fish in this area generally were low, and it is not known what effect this had. The catches were good compared with other shallow areas, but the fishes caught were mainly of medium quality. It is thought that significant increases in the quantity and quality of the catch could be obtained with commercial traps in deeper areas, but the efficient use of these would require new vessels and equipment, and the resulting increase in fishing effort could lead to overfishing of the most acceptable species of reef fish. Hence the development of fishery using fish traps is not recommended for Galápagos. A study of the biology of the fish caught was carried out. A bibliography of references on fish traps and their use was compiled and is included.

    Rapport national sur l'état de l'environnement marin et côtier (2009)
    Details
    Publication Date: 2021-01-30
    Description: Le domaine maritime sénégalais s’étend de 18°00 N, -20°00 W, -16°30 E, 12°15 S ; la presqu’île du Cap-Vert située entre 14°30 N et 15°00 N le divise en deux zones aux caractéristiques topographiques distinctes. Au nord, le plateau continental est peu étendu vers le large et orienté Nord-Nord/Est. Au sud de la presqu’île, le plateau s’élargit et le talus continental est orienté nord-sud. L’embouchure du fleuve Sénégal au Sénégal au Nord de la presqu’île du Cap-Vert et celles de la Gambie et de la Casamance au Sud constituent également un trait marquant de cette région. Les travaux réalisés au Sénégal en océanographie ont montré : - l’existence de deux saisons marines aux caractéristiques très différentes qui se succèdent : une saison chaude de juillet à octobre et une saison froide de décembre à mai. Ces deux saisons sont séparées par des périodes de transition. Pendant la saison froide, les alizés (vent de secteur nord-ouest à nord-est) s’établissent et engendrent à la côte une résurgence d’eau profonde (upwelling) vers la surface ; - la mise en évidence de systèmes de grands courants aux caractéristiques différentes : le courant des Canaries et le contre courant équatorial ; - la description de trois grandes houles au large du Sénégal : o la houle de Nord-Nord ouest qui a lieu toute l’année o la houle de Sud-Sud ouest apparaissant pendant l’hivernage o la houle d’ouest possible aux environs du mois de novembre. Le littoral sénégalais représente une zone d’intérêt stratégique à la fois sur le plan démographique, économique et environnemental. Les milieux naturels, dans un état de conservation relativement préservé, produisent des ressources vitales pour les 11 millions d’habitants peuplant le Sénégal. L’économie nationale sénégalaise est très dépendante de ces ressources côtières et marines qui constituent les principales recettes en devises, qu’il s’agisse de pêche ou de tourisme. L’analyse de la situation et des tendances montre que la zone côtière fait l’objet de pressions diversifiées et de plus en plus lourdes. Ces pressions se traduisent souvent par des conflits d’intérêts entre les différents secteurs et par des impacts qui génèrent une dégradation de l’environnement et des conditions de vie des populations. Cette évolution risque ainsi de compromettre les potentialités de développement offertes par les 700 Km de littoral sénégalais. La pression démographique se développe préférentiellement sur la zone côtière qui accueille déjà près de 60% des habitants, notamment dans les centres urbains et les capitale, toutes situées en bord de mer, et qui continuent à recevoir des populations en provenance de l’intérieur, réfugiés climatiques ou économiques, ou simplement jeunesse attirée par les « lumières de la ville ». Cet exode, à l’origine de dysfonctionnements des systèmes de production ruraux qui manquent peu à peu de main d’oeuvre, contribue à son tour à générer des perturbations au niveau des centres urbains où la misère se substitue parfois à la pauvreté.
    Description: Les besoins en matériaux de construction consécutifs à cette évolution démographique entraînent des prélèvements massifs de sable sur les plages qui ont à leur tour des conséquences négatives sur l’érosion et la protection du littoral. La fragilisation des cordons dunaires augmente ainsi les risques d’inondations des terres, la ville de Saint Louis étant particulièrement vulnérable à cet égard. Les besoins en développement ont conduit à la réalisation d’infrastructures le long du littoral. Ces constructions, qui tiennent trop rarement compte des contraintes environnementales, ont entraîné des répercussions structurelles sur l’équilibre de la zone côtière. Ainsi, les barrages anti-sel, tel le barrage de Diama sur le fleuve Sénégal, ont entraîné des répercussions sur le fonctionnement de certains écosystèmes côtiers. En condamnant les influences des apports d’eau douce ils appauvrissent les milieux situés en aval, stérilisant peu à peu des zones riches en ressources ainsi que les économies et les cultures qui en dépendent. Le ralentissement des courants et la baisse de salinité en amont du barrage favorisent l’apparition de certaines plantes envahissantes, telles que la bilharziose ou le paludisme. Les effectifs de poissons dépendant de milieux à salinité variable sont directement affectés, expliquant par exemple une chute de près de 70% des captures dans le bas delta du Sénégal. Les besoins du développement se traduisent également par l’amélioration ou la création d’axes routiers qui, dans la majorité des cas, longent la zone côtière. Ces ouvrages entraînent des impacts directs sur l’environnement, tels la destruction des mangroves là où les routes barrent l’écoulement des marées (exemple de la route Samba Dia – Djifère. Les systèmes de production traditionnels sont en règle générale peu préparés à faire face à des circuits de commercialisation organisés à une échelle régionale ou internationale, où à des technologies plus performantes, et éprouvent des difficultés à maintenir un contrôle sur leur terroir. Faute de pouvoir opérer une métamorphose rapide de leur système de production, le risque existe de voir peu à peu disparaître des savoir-faire d’une grande valeur dans la gestion même de ces territoires et de leurs ressources et , plus généralement, des cultures qui leur sont associées. Le développement industriel exerce des impacts potentiels ou réels de grande magnitude sur la zone côtière et marine. Les secteurs les plus significatifs à cet égard sont le tourisme et les hydrocarbures. Concernant le premier, les infrastructures, principalement orientées vers le tourisme balnéaire, sont en grande majorité installées à proximité directe de la zone côtière. L’absence quasi généralisée d’études d’impacts approfondies et indépendantes a conduit à de nombreux échecs. Ainsi, la plupart des projets ont été pensés et réalisés sans tenir suffisamment compte des contextes socio-économiques, culturels et environnementaux dans lesquels ils s’insèrent. Certaines réalisations ont été planifiées sur des secteurs soumis à une forte érosion littorale, compromettant de façon irrémédiable non seulement les investissements mais l’utilisation ultérieure du site, comme cela s’est produit sur les plages au sud immédiat du Cap Skirring. Les questions relatives à la disponibilité en eau douce qui se posent de façon cruciale dans le Saloum par exemple, à la gestion des déchets et des eaux usées ne sont que rarement prises en considération de façon structurelle et durable, conduisant à la dégradation de l’environnement ou à des conflits avec les communautés locales qui nuisent à la qualité même du tourisme. L’exploration et l’exploitation des ressources en hydrocarbures représentent aussi un secteur d’intérêt stratégique avec une généralisation des prospections. Si la découverte de gisement d’intérêt commercial représente une opportunité majeure pour l’économie nationale, elle soulève néanmoins un certain nombre de questions au regard de l’environnement. En effet les des puits. Parmi ces risques nous pouvons citer les impacts des études sismiques sur les organismes marins, notamment poissons et cétacés, le rejet de fluides toxiques et déblais de forage, le déversement des eaux de production et les pollutions aiguës dues à des accidents intervenant pendant le forage, le stockage ou le transport. Le Sénégal en ce moment, en est au stade de la prospection. Toutefois, pour ce qui concerne le transport d’hydrocarbures, plus de 90 000 0000 de tonnes d’hydrocarbures transitent par les côtes sénégalaises. Les modèles de dérive des nappes élaborés par la Compagnie pétrolière Woodside en relation avec le champ de Chinguetti, actuellement en cours de production au large de la Mauritanie, montrent des probabilités d’impact sur les côtes allant du golfe d’Arguin jusqu’à Dakar, en cas d’accident. La surexploitation des ressources halieutiques constitue également un problème au niveau de l’environnement marin et côtier. En effet, si une partie de la fluctuation des biomasses peut s’expliquer par les changements du régime des upwellings, la baisse des captures s’explique par un effort de pêche excessif, que ce soit dans le sous-secteur industriel ou artisanal. A cette surcapacité vient s’ajouter la présence de flottes illicites non déclarées et non réglementées. L’utilisation de certains engins ou pratiques de pêche contribue à aggraver la situation : la pêche crevettière est à l’origine de prises accidentelles qui représentent jusqu’à 85 % du total des captures, incluant des espèces protégées comme les tortues marines, et qui sont rejetés à la mer . Les chaluts de fonds, qui vont pêcher jusqu’à 800 m de profondeur, ainsi que les dragues à coquillages entraînant des dégâts structurels sur les écosystèmes De plus l’influence des marchés à l’exportation exerce des pressions sélectives sur certaines espèces, les espèces démersales de poissons, céphalopodes étant les plus recherchées sur le marché. Les changements climatiques ont également des impacts négatifs sur l’environnement marin et côtier. On sait que l’élévation du niveau marin aura des répercussions directes sur les installations humaines littorales ainsi que sur les écosystèmes insulaires et côtiers. Des zones de mangroves entières qui ne disposent pas des conditions écologiques pour s’adapter peuvent disparaître, entraînant des risques accrus d’érosion et d’inondation. Ces mêmes risques se multiplient avec la fréquence accrue des épisodes météorologiques exceptionnels tels que les ondes de tempêtes capables de drosser les pirogues à la côte ou de provoquer la rupture de cordons dunaires. On sait par ailleurs que le réchauffement de la température des mers influe négativement sur la productivité des océans et la dynamique des courants tels que le courant profond originaire de l’antarctique et qui exporte vers le Sénégal et les autres pays de la sousrégion des sels nutritifs présents dans les upwellings. On observe également une diminution de la puissance des alizés qui pourrait avoir des répercussions directes sur la force des upwellings et donc sur la productivité des pêcheries et du milieu marin en général. La stratégie de réponse proposée combine une protection des zones côtières importantes et un reboisement des dunes littorales dans les secteurs de la côte nord et de la Flèche de Sangomar particulièrement menacés. L’évaluation économique de cette stratégie montre qu’elle est coûteuse mais nettement en deçà de la valeur économique des terres qu’elle sera amenée à protéger. Des efforts complémentaires devront cependant être faits pour évaluer le coût d’autres solutions de protection telles que le nourissement artificiel des plages. Par ailleurs, la stratégie envisagée ne répondant qu’à l’un des impacts des changements climatiques, à savoir les inondations, toute une série de mesures dites d’accompagnement ont été suggérées qui visent à diminuer la vulnérabilité en gérant mieux les ressources présentes dans la zone côtière, en développant les techniques de récupération des sols salés et en prenant des mesures législatives et institutionnelles appropriées. Enfin, il est très important de souligner que ces différentes mesures ne devraient être envisagées que dans un cadre plus global de gestion intégrée des zones côtières, seul à même d’assurer la participation de l’ensemble des acteurs concernés, l’éducation, la recherche et l’information environnementales mais aussi la cohérences et le suivi des mesures.

    From Farming to Fishing: Marine Resource Conservation (2009)
    Western Indian Ocean Marine Science Association
    Details
    Publication Date: 2021-05-19
    Description: This paper examines the arrival of a new group of fishermen on the Kenyan coast and what this has meant for the state of fishery resources. It reviews four subject areas: access and the number of fishermen; the fishermen’s identity; the choice of fishing gear; and the fishing grounds selected. Data were collected from a small number of fishing households in the villages of Uyombo and Takaungu in Kilifi District, using mainly qualitative research methods. Local households on the Kenyan coast face increasing pressure on land as well as on marine resources. The declining economic situation and greater pressure on land have made people turn to fishing as an income-generating activity. This group of fishermen is referred to as the ‘new’ generation of fishermen as they have been involved in fishing for only one or two generations (including the current one) in contrast to the ‘old’ generation from families who have been fishing or in fishingrelated activities for much longer. The old generation of fishermen and their households have also diversified their incomes, with many fishing households turning to farming, for example, with women and grown-up children involved in various activities. The new generation of fishermen, mainly of the Mijikenda population group, has often been blamed for the loss of traditional access regulations and for using harmful fishing gear. This paper discusses the new generation of fishermen and their identity as they perceive it and relates this to employment generation as a policy measure for marine conservation.

    Origins and functional impact of copy number variation in the human genome (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-10-09
    Description: Structural variations of DNA greater than 1 kilobase in size account for most bases that vary among human genomes, but are still relatively under-ascertained. Here we use tiling oligonucleotide microarrays, comprising 42 million probes, to generate a comprehensive map of 11,700 copy number variations (CNVs) greater than 443 base pairs, of which most (8,599) have been validated independently. For 4,978 of these CNVs, we generated reference genotypes from 450 individuals of European, African or East Asian ancestry. The predominant mutational mechanisms differ among CNV size classes. Retrotransposition has duplicated and inserted some coding and non-coding DNA segments randomly around the genome. Furthermore, by correlation with known trait-associated single nucleotide polymorphisms (SNPs), we identified 30 loci with CNVs that are candidates for influencing disease susceptibility. Despite this, having assessed the completeness of our map and the patterns of linkage disequilibrium between CNVs and SNPs, we conclude that, for complex traits, the heritability void left by genome-wide association studies will not be accounted for by common CNVs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3330748/" 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/PMC3330748/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Conrad, Donald F -- Pinto, Dalila -- Redon, Richard -- Feuk, Lars -- Gokcumen, Omer -- Zhang, Yujun -- Aerts, Jan -- Andrews, T Daniel -- Barnes, Chris -- Campbell, Peter -- Fitzgerald, Tomas -- Hu, Min -- Ihm, Chun Hwa -- Kristiansson, Kati -- Macarthur, Daniel G -- Macdonald, Jeffrey R -- Onyiah, Ifejinelo -- Pang, Andy Wing Chun -- Robson, Sam -- Stirrups, Kathy -- Valsesia, Armand -- Walter, Klaudia -- Wei, John -- Wellcome Trust Case Control Consortium -- Tyler-Smith, Chris -- Carter, Nigel P -- Lee, Charles -- Scherer, Stephen W -- Hurles, Matthew E -- 077006/Z/05/Z/Wellcome Trust/United Kingdom -- 077008/Wellcome Trust/United Kingdom -- 077009/Wellcome Trust/United Kingdom -- 077014/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- GM081533/GM/NIGMS NIH HHS/ -- HG004221/HG/NHGRI NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2010 Apr 1;464(7289):704-12. doi: 10.1038/nature08516.

    Description: Reprogramming of somatic cell nuclei to yield induced pluripotent stem (iPS) cells makes possible derivation of patient-specific stem cells for regenerative medicine. However, iPS cell generation is asynchronous and slow (2-3 weeks), the frequency is low (〈0.1%), and DNA demethylation constitutes a bottleneck. To determine regulatory mechanisms involved in reprogramming, we generated interspecies heterokaryons (fused mouse embryonic stem (ES) cells and human fibroblasts) that induce reprogramming synchronously, frequently and fast. Here we show that reprogramming towards pluripotency in single heterokaryons is initiated without cell division or DNA replication, rapidly (1 day) and efficiently (70%). Short interfering RNA (siRNA)-mediated knockdown showed that activation-induced cytidine deaminase (AID, also known as AICDA) is required for promoter demethylation and induction of OCT4 (also known as POU5F1) and NANOG gene expression. AID protein bound silent methylated OCT4 and NANOG promoters in fibroblasts, but not active demethylated promoters in ES cells. These data provide new evidence that mammalian AID is required for active DNA demethylation and initiation of nuclear reprogramming towards pluripotency in human somatic cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2906123/" 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/PMC2906123/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bhutani, Nidhi -- Brady, Jennifer J -- Damian, Mara -- Sacco, Alessandra -- Corbel, Stephane Y -- Blau, Helen M -- AG009521/AG/NIA NIH HHS/ -- AG024987/AG/NIA NIH HHS/ -- AI007328/AI/NIAID NIH HHS/ -- R01 AG009521/AG/NIA NIH HHS/ -- R01 AG009521-25/AG/NIA NIH HHS/ -- R01 AG024987/AG/NIA NIH HHS/ -- R01 AG024987-05/AG/NIA NIH HHS/ -- T32 AI007328/AI/NIAID NIH HHS/ -- U01 HL100397/HL/NHLBI NIH HHS/ -- England -- Nature. 2010 Feb 25;463(7284):1042-7. doi: 10.1038/nature08752.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Baxter Laboratory for Stem Cell Biology, Institute for Stem Cell Biology and Regenerative Medicine, Department of Microbiology and Immunology, Stanford University School of Medicine, Stanford, California 94305-5175, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20027182" target="_blank"〉PubMed〈/a〉

    The sequence and de novo assembly of the giant panda genome (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-17
    Description: Using next-generation sequencing technology alone, we have successfully generated and assembled a draft sequence of the giant panda genome. The assembled contigs (2.25 gigabases (Gb)) cover approximately 94% of the whole genome, and the remaining gaps (0.05 Gb) seem to contain carnivore-specific repeats and tandem repeats. Comparisons with the dog and human showed that the panda genome has a lower divergence rate. The assessment of panda genes potentially underlying some of its unique traits indicated that its bamboo diet might be more dependent on its gut microbiome than its own genetic composition. We also identified more than 2.7 million heterozygous single nucleotide polymorphisms in the diploid genome. Our data and analyses provide a foundation for promoting mammalian genetic research, and demonstrate the feasibility for using next-generation sequencing technologies for accurate, cost-effective and rapid de novo assembly of large eukaryotic genomes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951497/" 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/PMC3951497/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Ruiqiang -- Fan, Wei -- Tian, Geng -- Zhu, Hongmei -- He, Lin -- Cai, Jing -- Huang, Quanfei -- Cai, Qingle -- Li, Bo -- Bai, Yinqi -- Zhang, Zhihe -- Zhang, Yaping -- Wang, Wen -- Li, Jun -- Wei, Fuwen -- Li, Heng -- Jian, Min -- Li, Jianwen -- Zhang, Zhaolei -- Nielsen, Rasmus -- Li, Dawei -- Gu, Wanjun -- Yang, Zhentao -- Xuan, Zhaoling -- Ryder, Oliver A -- Leung, Frederick Chi-Ching -- Zhou, Yan -- Cao, Jianjun -- Sun, Xiao -- Fu, Yonggui -- Fang, Xiaodong -- Guo, Xiaosen -- Wang, Bo -- Hou, Rong -- Shen, Fujun -- Mu, Bo -- Ni, Peixiang -- Lin, Runmao -- Qian, Wubin -- Wang, Guodong -- Yu, Chang -- Nie, Wenhui -- Wang, Jinhuan -- Wu, Zhigang -- Liang, Huiqing -- Min, Jiumeng -- Wu, Qi -- Cheng, Shifeng -- Ruan, Jue -- Wang, Mingwei -- Shi, Zhongbin -- Wen, Ming -- Liu, Binghang -- Ren, Xiaoli -- Zheng, Huisong -- Dong, Dong -- Cook, Kathleen -- Shan, Gao -- Zhang, Hao -- Kosiol, Carolin -- Xie, Xueying -- Lu, Zuhong -- Zheng, Hancheng -- Li, Yingrui -- Steiner, Cynthia C -- Lam, Tommy Tsan-Yuk -- Lin, Siyuan -- Zhang, Qinghui -- Li, Guoqing -- Tian, Jing -- Gong, Timing -- Liu, Hongde -- Zhang, Dejin -- Fang, Lin -- Ye, Chen -- Zhang, Juanbin -- Hu, Wenbo -- Xu, Anlong -- Ren, Yuanyuan -- Zhang, Guojie -- Bruford, Michael W -- Li, Qibin -- Ma, Lijia -- Guo, Yiran -- An, Na -- Hu, Yujie -- Zheng, Yang -- Shi, Yongyong -- Li, Zhiqiang -- Liu, Qing -- Chen, Yanling -- Zhao, Jing -- Qu, Ning -- Zhao, Shancen -- Tian, Feng -- Wang, Xiaoling -- Wang, Haiyin -- Xu, Lizhi -- Liu, Xiao -- Vinar, Tomas -- Wang, Yajun -- Lam, Tak-Wah -- Yiu, Siu-Ming -- Liu, Shiping -- Zhang, Hemin -- Li, Desheng -- Huang, Yan -- Wang, Xia -- Yang, Guohua -- Jiang, Zhi -- Wang, Junyi -- Qin, Nan -- Li, Li -- Li, Jingxiang -- Bolund, Lars -- Kristiansen, Karsten -- Wong, Gane Ka-Shu -- Olson, Maynard -- Zhang, Xiuqing -- Li, Songgang -- Yang, Huanming -- Wang, Jian -- Wang, Jun -- R01 HG003229/HG/NHGRI NIH HHS/ -- R01 HG003229-05/HG/NHGRI NIH HHS/ -- England -- Nature. 2010 Jan 21;463(7279):311-7. doi: 10.1038/nature08696.

    A comprehensive catalogue of somatic mutations from a human cancer genome (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-18
    Description: All cancers carry somatic mutations. A subset of these somatic alterations, termed driver mutations, confer selective growth advantage and are implicated in cancer development, whereas the remainder are passengers. Here we have sequenced the genomes of a malignant melanoma and a lymphoblastoid cell line from the same person, providing the first comprehensive catalogue of somatic mutations from an individual cancer. The catalogue provides remarkable insights into the forces that have shaped this cancer genome. The dominant mutational signature reflects DNA damage due to ultraviolet light exposure, a known risk factor for malignant melanoma, whereas the uneven distribution of mutations across the genome, with a lower prevalence in gene footprints, indicates that DNA repair has been preferentially deployed towards transcribed regions. The results illustrate the power of a cancer genome sequence to reveal traces of the DNA damage, repair, mutation and selection processes that were operative years before the cancer became symptomatic.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3145108/" 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/PMC3145108/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pleasance, Erin D -- Cheetham, R Keira -- Stephens, Philip J -- McBride, David J -- Humphray, Sean J -- Greenman, Chris D -- Varela, Ignacio -- Lin, Meng-Lay -- Ordonez, Gonzalo R -- Bignell, Graham R -- Ye, Kai -- Alipaz, Julie -- Bauer, Markus J -- Beare, David -- Butler, Adam -- Carter, Richard J -- Chen, Lina -- Cox, Anthony J -- Edkins, Sarah -- Kokko-Gonzales, Paula I -- Gormley, Niall A -- Grocock, Russell J -- Haudenschild, Christian D -- Hims, Matthew M -- James, Terena -- Jia, Mingming -- Kingsbury, Zoya -- Leroy, Catherine -- Marshall, John -- Menzies, Andrew -- Mudie, Laura J -- Ning, Zemin -- Royce, Tom -- Schulz-Trieglaff, Ole B -- Spiridou, Anastassia -- Stebbings, Lucy A -- Szajkowski, Lukasz -- Teague, Jon -- Williamson, David -- Chin, Lynda -- Ross, Mark T -- Campbell, Peter J -- Bentley, David R -- Futreal, P Andrew -- Stratton, Michael R -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- England -- Nature. 2010 Jan 14;463(7278):191-6. doi: 10.1038/nature08658.

    Crystal structure of DNA-PKcs reveals a large open-ring cradle comprised of HEAT repeats (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-22
    Description: Broken chromosomes arising from DNA double-strand breaks result from endogenous events such as the production of reactive oxygen species during cellular metabolism, as well as from exogenous sources such as ionizing radiation. Left unrepaired or incorrectly repaired they can lead to genomic changes that may result in cell death or cancer. DNA-dependent protein kinase (DNA-PK), a holoenzyme that comprises the DNA-PK catalytic subunit (DNA-PKcs) and the heterodimer Ku70/Ku80, has a major role in non-homologous end joining-the main pathway in mammals used to repair double-strand breaks. DNA-PKcs is a serine/threonine protein kinase comprising a single polypeptide chain of 4,128 amino acids and belonging to the phosphatidylinositol-3-OH kinase (PI(3)K)-related protein family. DNA-PKcs is involved in the sensing and transmission of DNA damage signals to proteins such as p53, setting off events that lead to cell cycle arrest. It phosphorylates a wide range of substrates in vitro, including Ku70/Ku80, which is translocated along DNA. Here we present the crystal structure of human DNA-PKcs at 6.6 A resolution, in which the overall fold is clearly visible, to our knowledge, for the first time. The many alpha-helical HEAT repeats (helix-turn-helix motifs) facilitate bending and allow the polypeptide chain to fold into a hollow circular structure. The carboxy-terminal kinase domain is located on top of this structure, and a small HEAT repeat domain that probably binds DNA is inside. The structure provides a flexible cradle to promote DNA double-strand-break repair.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2811870/" 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/PMC2811870/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sibanda, Bancinyane L -- Chirgadze, Dimitri Y -- Blundell, Tom L -- 079281/Wellcome Trust/United Kingdom -- A3846/Cancer Research UK/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2010 Jan 7;463(7277):118-21. doi: 10.1038/nature08648.

    Preventing the return of fear in humans using reconsolidation update mechanisms (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-17
    Description: Recent research on changing fears has examined targeting reconsolidation. During reconsolidation, stored information is rendered labile after being retrieved. Pharmacological manipulations at this stage result in an inability to retrieve the memories at later times, suggesting that they are erased or persistently inhibited. Unfortunately, the use of these pharmacological manipulations in humans can be problematic. Here we introduce a non-invasive technique to target the reconsolidation of fear memories in humans. We provide evidence that old fear memories can be updated with non-fearful information provided during the reconsolidation window. As a consequence, fear responses are no longer expressed, an effect that lasted at least a year and was selective only to reactivated memories without affecting others. These findings demonstrate the adaptive role of reconsolidation as a window of opportunity to rewrite emotional memories, and suggest a non-invasive technique that can be used safely in humans to prevent the return of fear.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3640262/" 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/PMC3640262/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schiller, Daniela -- Monfils, Marie-H -- Raio, Candace M -- Johnson, David C -- Ledoux, Joseph E -- Phelps, Elizabeth A -- K05 MH067048/MH/NIMH NIH HHS/ -- P50 MH058911/MH/NIMH NIH HHS/ -- R01 MH038774/MH/NIMH NIH HHS/ -- R01 MH046516/MH/NIMH NIH HHS/ -- R21 MH072279/MH/NIMH NIH HHS/ -- R37 MH038774/MH/NIMH NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2010 Jan 7;463(7277):49-53. doi: 10.1038/nature08637.

    Disease-corrected haematopoietic progenitors from Fanconi anaemia induced pluripotent stem cells (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-06-02
    Description: The generation of induced pluripotent stem (iPS) cells has enabled the derivation of patient-specific pluripotent cells and provided valuable experimental platforms to model human disease. Patient-specific iPS cells are also thought to hold great therapeutic potential, although direct evidence for this is still lacking. Here we show that, on correction of the genetic defect, somatic cells from Fanconi anaemia patients can be reprogrammed to pluripotency to generate patient-specific iPS cells. These cell lines appear indistinguishable from human embryonic stem cells and iPS cells from healthy individuals. Most importantly, we show that corrected Fanconi-anaemia-specific iPS cells can give rise to haematopoietic progenitors of the myeloid and erythroid lineages that are phenotypically normal, that is, disease-free.

    Frequent inactivation of A20 in B-cell lymphomas (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-05-05
    Description: A20 is a negative regulator of the NF-kappaB pathway and was initially identified as being rapidly induced after tumour-necrosis factor-alpha stimulation. It has a pivotal role in regulation of the immune response and prevents excessive activation of NF-kappaB in response to a variety of external stimuli; recent genetic studies have disclosed putative associations of polymorphic A20 (also called TNFAIP3) alleles with autoimmune disease risk. However, the involvement of A20 in the development of human cancers is unknown. Here we show, using a genome-wide analysis of genetic lesions in 238 B-cell lymphomas, that A20 is a common genetic target in B-lineage lymphomas. A20 is frequently inactivated by somatic mutations and/or deletions in mucosa-associated tissue lymphoma (18 out of 87; 21.8%) and Hodgkin's lymphoma of nodular sclerosis histology (5 out of 15; 33.3%), and, to a lesser extent, in other B-lineage lymphomas. When re-expressed in a lymphoma-derived cell line with no functional A20 alleles, wild-type A20, but not mutant A20, resulted in suppression of cell growth and induction of apoptosis, accompanied by downregulation of NF-kappaB activation. The A20-deficient cells stably generated tumours in immunodeficient mice, whereas the tumorigenicity was effectively suppressed by re-expression of A20. In A20-deficient cells, suppression of both cell growth and NF-kappaB activity due to re-expression of A20 depended, at least partly, on cell-surface-receptor signalling, including the tumour-necrosis factor receptor. Considering the physiological function of A20 in the negative modulation of NF-kappaB activation induced by multiple upstream stimuli, our findings indicate that uncontrolled signalling of NF-kappaB caused by loss of A20 function is involved in the pathogenesis of subsets of B-lineage lymphomas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kato, Motohiro -- Sanada, Masashi -- Kato, Itaru -- Sato, Yasuharu -- Takita, Junko -- Takeuchi, Kengo -- Niwa, Akira -- Chen, Yuyan -- Nakazaki, Kumi -- Nomoto, Junko -- Asakura, Yoshitaka -- Muto, Satsuki -- Tamura, Azusa -- Iio, Mitsuru -- Akatsuka, Yoshiki -- Hayashi, Yasuhide -- Mori, Hiraku -- Igarashi, Takashi -- Kurokawa, Mineo -- Chiba, Shigeru -- Mori, Shigeo -- Ishikawa, Yuichi -- Okamoto, Koji -- Tobinai, Kensei -- Nakagama, Hitoshi -- Nakahata, Tatsutoshi -- Yoshino, Tadashi -- Kobayashi, Yukio -- Ogawa, Seishi -- England -- Nature. 2009 Jun 4;459(7247):712-6. doi: 10.1038/nature07969.

    Pore architecture and ion sites in acid-sensing ion channels and P2X receptors (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-07-31
    Description: Acid-sensing ion channels are proton-activated, sodium-selective channels composed of three subunits, and are members of the superfamily of epithelial sodium channels, mechanosensitive and FMRF-amide peptide-gated ion channels. These ubiquitous eukaryotic ion channels have essential roles in biological activities as diverse as sodium homeostasis, taste and pain. Despite their crucial roles in biology and their unusual trimeric subunit stoichiometry, there is little knowledge of the structural and chemical principles underlying their ion channel architecture and ion-binding sites. Here we present the structure of a functional acid-sensing ion channel in a desensitized state at 3 A resolution, the location and composition of the approximately 8 A 'thick' desensitization gate, and the trigonal antiprism coordination of caesium ions bound in the extracellular vestibule. Comparison of the acid-sensing ion channel structure with the ATP-gated P2X(4) receptor reveals similarity in pore architecture and aqueous vestibules, suggesting that there are unanticipated yet common structural and mechanistic principles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2845979/" 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/PMC2845979/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gonzales, Eric B -- Kawate, Toshimitsu -- Gouaux, Eric -- F32 GM083615/GM/NIGMS NIH HHS/ -- F32 GM083615-01/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 Jul 30;460(7255):599-604. doi: 10.1038/nature08218.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health and Science University, 3181 Southwest Sam Jackson Park Road, Portland, Oregon 97239, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19641589" target="_blank"〉PubMed〈/a〉

    Zc3h12a is an RNase essential for controlling immune responses by regulating mRNA decay (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-03-27
    Description: Toll-like receptors (TLRs) recognize microbial components, and evoke inflammation and immune responses. TLR stimulation activates complex gene expression networks that regulate the magnitude and duration of the immune reaction. Here we identify the TLR-inducible gene Zc3h12a as an immune response modifier that has an essential role in preventing immune disorders. Zc3h12a-deficient mice suffered from severe anaemia, and most died within 12 weeks. Zc3h12a(-/-) mice also showed augmented serum immunoglobulin levels and autoantibody production, together with a greatly increased number of plasma cells, as well as infiltration of plasma cells to the lung. Most Zc3h12a(-/-) splenic T cells showed effector/memory characteristics and produced interferon-gamma in response to T-cell receptor stimulation. Macrophages from Zc3h12a(-/-) mice showed highly increased production of interleukin (IL)-6 and IL-12p40 (also known as IL12b), but not TNF, in response to TLR ligands. Although the activation of TLR signalling pathways was normal, Il6 messenger RNA decay was severely impaired in Zc3h12a(-/-) macrophages. Overexpression of Zc3h12a accelerated Il6 mRNA degradation via its 3'-untranslated region (UTR), and destabilized RNAs with 3'-UTRs for genes including Il6, Il12p40 and the calcitonin receptor gene Calcr. Zc3h12a contains a putative amino-terminal nuclease domain, and the expressed protein had RNase activity, consistent with a role in the decay of Il6 mRNA. Together, these results indicate that Zc3h12a is an essential RNase that prevents immune disorders by directly controlling the stability of a set of inflammatory genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsushita, Kazufumi -- Takeuchi, Osamu -- Standley, Daron M -- Kumagai, Yutaro -- Kawagoe, Tatsukata -- Miyake, Tohru -- Satoh, Takashi -- Kato, Hiroki -- Tsujimura, Tohru -- Nakamura, Haruki -- Akira, Shizuo -- P01 AI070167/AI/NIAID NIH HHS/ -- England -- Nature. 2009 Apr 30;458(7242):1185-90. doi: 10.1038/nature07924.

    Linking the p53 tumour suppressor pathway to somatic cell reprogramming (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-08-12
    Description: Reprogramming somatic cells to induced pluripotent stem (iPS) cells has been accomplished by expressing pluripotency factors and oncogenes, but the low frequency and tendency to induce malignant transformation compromise the clinical utility of this powerful approach. We address both issues by investigating the mechanisms limiting reprogramming efficiency in somatic cells. Here we show that reprogramming factors can activate the p53 (also known as Trp53 in mice, TP53 in humans) pathway. Reducing signalling to p53 by expressing a mutated version of one of its negative regulators, by deleting or knocking down p53 or its target gene, p21 (also known as Cdkn1a), or by antagonizing reprogramming-induced apoptosis in mouse fibroblasts increases reprogramming efficiency. Notably, decreasing p53 protein levels enabled fibroblasts to give rise to iPS cells capable of generating germline-transmitting chimaeric mice using only Oct4 (also known as Pou5f1) and Sox2. Furthermore, silencing of p53 significantly increased the reprogramming efficiency of human somatic cells. These results provide insights into reprogramming mechanisms and suggest new routes to more efficient reprogramming while minimizing the use of oncogenes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2735889/" 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/PMC2735889/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawamura, Teruhisa -- Suzuki, Jotaro -- Wang, Yunyuan V -- Menendez, Sergio -- Morera, Laura Batlle -- Raya, Angel -- Wahl, Geoffrey M -- Izpisua Belmonte, Juan Carlos -- 5 R01 CA061449/CA/NCI NIH HHS/ -- 5 R01 CA100845/CA/NCI NIH HHS/ -- R01 CA061449/CA/NCI NIH HHS/ -- R01 CA061449-30/CA/NCI NIH HHS/ -- R01 CA100845/CA/NCI NIH HHS/ -- R01 CA100845-05/CA/NCI NIH HHS/ -- R33 HL088293/HL/NHLBI NIH HHS/ -- R33 HL088293-03/HL/NHLBI NIH HHS/ -- England -- Nature. 2009 Aug 27;460(7259):1140-4. doi: 10.1038/nature08311.

    Adaptation of HIV-1 to human leukocyte antigen class I (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-02-27
    Description: The rapid and extensive spread of the human immunodeficiency virus (HIV) epidemic provides a rare opportunity to witness host-pathogen co-evolution involving humans. A focal point is the interaction between genes encoding human leukocyte antigen (HLA) and those encoding HIV proteins. HLA molecules present fragments (epitopes) of HIV proteins on the surface of infected cells to enable immune recognition and killing by CD8(+) T cells; particular HLA molecules, such as HLA-B*57, HLA-B*27 and HLA-B*51, are more likely to mediate successful control of HIV infection. Mutation within these epitopes can allow viral escape from CD8(+) T-cell recognition. Here we analysed viral sequences and HLA alleles from 〉2,800 subjects, drawn from 9 distinct study cohorts spanning 5 continents. Initial analysis of the HLA-B*51-restricted epitope, TAFTIPSI (reverse transcriptase residues 128-135), showed a strong correlation between the frequency of the escape mutation I135X and HLA-B*51 prevalence in the 9 study cohorts (P = 0.0001). Extending these analyses to incorporate other well-defined CD8(+) T-cell epitopes, including those restricted by HLA-B*57 and HLA-B*27, showed that the frequency of these epitope variants (n = 14) was consistently correlated with the prevalence of the restricting HLA allele in the different cohorts (together, P 〈 0.0001), demonstrating strong evidence of HIV adaptation to HLA at a population level. This process of viral adaptation may dismantle the well-established HLA associations with control of HIV infection that are linked to the availability of key epitopes, and highlights the challenge for a vaccine to keep pace with the changing immunological landscape presented by HIV.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3148020/" 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/PMC3148020/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawashima, Yuka -- Pfafferott, Katja -- Frater, John -- Matthews, Philippa -- Payne, Rebecca -- Addo, Marylyn -- Gatanaga, Hiroyuki -- Fujiwara, Mamoru -- Hachiya, Atsuko -- Koizumi, Hirokazu -- Kuse, Nozomi -- Oka, Shinichi -- Duda, Anna -- Prendergast, Andrew -- Crawford, Hayley -- Leslie, Alasdair -- Brumme, Zabrina -- Brumme, Chanson -- Allen, Todd -- Brander, Christian -- Kaslow, Richard -- Tang, James -- Hunter, Eric -- Allen, Susan -- Mulenga, Joseph -- Branch, Songee -- Roach, Tim -- John, Mina -- Mallal, Simon -- Ogwu, Anthony -- Shapiro, Roger -- Prado, Julia G -- Fidler, Sarah -- Weber, Jonathan -- Pybus, Oliver G -- Klenerman, Paul -- Ndung'u, Thumbi -- Phillips, Rodney -- Heckerman, David -- Harrigan, P Richard -- Walker, Bruce D -- Takiguchi, Masafumi -- Goulder, Philip -- 1 R01 AI067073/AI/NIAID NIH HHS/ -- G0500384/Medical Research Council/United Kingdom -- G0501777/Medical Research Council/United Kingdom -- G108/626/Medical Research Council/United Kingdom -- R01 AI046995/AI/NIAID NIH HHS/ -- R01 AI046995-10/AI/NIAID NIH HHS/ -- R01 AI060460/AI/NIAID NIH HHS/ -- R01 AI064060/AI/NIAID NIH HHS/ -- R01 AI064060-06A1/AI/NIAID NIH HHS/ -- R01AI46995/AI/NIAID NIH HHS/ -- R01AI64060/AI/NIAID NIH HHS/ -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2009 Apr 2;458(7238):641-5. doi: 10.1038/nature07746.

    Reconstructing Indian population history (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-09-26
    Description: India has been underrepresented in genome-wide surveys of human variation. We analyse 25 diverse groups in India to provide strong evidence for two ancient populations, genetically divergent, that are ancestral to most Indians today. One, the 'Ancestral North Indians' (ANI), is genetically close to Middle Easterners, Central Asians, and Europeans, whereas the other, the 'Ancestral South Indians' (ASI), is as distinct from ANI and East Asians as they are from each other. By introducing methods that can estimate ancestry without accurate ancestral populations, we show that ANI ancestry ranges from 39-71% in most Indian groups, and is higher in traditionally upper caste and Indo-European speakers. Groups with only ASI ancestry may no longer exist in mainland India. However, the indigenous Andaman Islanders are unique in being ASI-related groups without ANI ancestry. Allele frequency differences between groups in India are larger than in Europe, reflecting strong founder effects whose signatures have been maintained for thousands of years owing to endogamy. We therefore predict that there will be an excess of recessive diseases in India, which should be possible to screen and map genetically.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2842210/" 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/PMC2842210/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reich, David -- Thangaraj, Kumarasamy -- Patterson, Nick -- Price, Alkes L -- Singh, Lalji -- HG004168/HG/NHGRI NIH HHS/ -- R01 HG006399/HG/NHGRI NIH HHS/ -- U01 HG004168/HG/NHGRI NIH HHS/ -- U01 HG004168-03/HG/NHGRI NIH HHS/ -- England -- Nature. 2009 Sep 24;461(7263):489-94. doi: 10.1038/nature08365.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Boston, Massachusetts 02115, USA. reich@genetics.med.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19779445" target="_blank"〉PubMed〈/a〉

    Cancer-associated IDH1 mutations produce 2-hydroxyglutarate (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-26
    Description: Mutations in the enzyme cytosolic isocitrate dehydrogenase 1 (IDH1) are a common feature of a major subset of primary human brain cancers. These mutations occur at a single amino acid residue of the IDH1 active site, resulting in loss of the enzyme's ability to catalyse conversion of isocitrate to alpha-ketoglutarate. However, only a single copy of the gene is mutated in tumours, raising the possibility that the mutations do not result in a simple loss of function. Here we show that cancer-associated IDH1 mutations result in a new ability of the enzyme to catalyse the NADPH-dependent reduction of alpha-ketoglutarate to R(-)-2-hydroxyglutarate (2HG). Structural studies demonstrate that when arginine 132 is mutated to histidine, residues in the active site are shifted to produce structural changes consistent with reduced oxidative decarboxylation of isocitrate and acquisition of the ability to convert alpha-ketoglutarate to 2HG. Excess accumulation of 2HG has been shown to lead to an elevated risk of malignant brain tumours in patients with inborn errors of 2HG metabolism. Similarly, in human malignant gliomas harbouring IDH1 mutations, we find markedly elevated levels of 2HG. These data demonstrate that the IDH1 mutations result in production of the onco-metabolite 2HG, and indicate that the excess 2HG which accumulates in vivo contributes to the formation and malignant progression of gliomas.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2818760/" 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/PMC2818760/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dang, Lenny -- White, David W -- Gross, Stefan -- Bennett, Bryson D -- Bittinger, Mark A -- Driggers, Edward M -- Fantin, Valeria R -- Jang, Hyun Gyung -- Jin, Shengfang -- Keenan, Marie C -- Marks, Kevin M -- Prins, Robert M -- Ward, Patrick S -- Yen, Katharine E -- Liau, Linda M -- Rabinowitz, Joshua D -- Cantley, Lewis C -- Thompson, Craig B -- Vander Heiden, Matthew G -- Su, Shinsan M -- P01 CA104838/CA/NCI NIH HHS/ -- P01 CA104838-05/CA/NCI NIH HHS/ -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 CA105463/CA/NCI NIH HHS/ -- R01 CA105463-06/CA/NCI NIH HHS/ -- R21 CA128620/CA/NCI NIH HHS/ -- England -- Nature. 2009 Dec 10;462(7274):739-44. doi: 10.1038/nature08617.

    Modulation of microRNA processing by p53 (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-07-25
    Description: MicroRNAs (miRNAs) have emerged as key post-transcriptional regulators of gene expression, involved in diverse physiological and pathological processes. Although miRNAs can function as both tumour suppressors and oncogenes in tumour development, a widespread downregulation of miRNAs is commonly observed in human cancers and promotes cellular transformation and tumorigenesis. This indicates an inherent significance of small RNAs in tumour suppression. However, the connection between tumour suppressor networks and miRNA biogenesis machineries has not been investigated in depth. Here we show that a central tumour suppressor, p53, enhances the post-transcriptional maturation of several miRNAs with growth-suppressive function, including miR-16-1, miR-143 and miR-145, in response to DNA damage. In HCT116 cells and human diploid fibroblasts, p53 interacts with the Drosha processing complex through the association with DEAD-box RNA helicase p68 (also known as DDX5) and facilitates the processing of primary miRNAs to precursor miRNAs. We also found that transcriptionally inactive p53 mutants interfere with a functional assembly between Drosha complex and p68, leading to attenuation of miRNA processing activity. These findings suggest that transcription-independent modulation of miRNA biogenesis is intrinsically embedded in a tumour suppressive program governed by p53. Our study reveals a previously unrecognized function of p53 in miRNA processing, which may underlie key aspects of cancer biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suzuki, Hiroshi I -- Yamagata, Kaoru -- Sugimoto, Koichi -- Iwamoto, Takashi -- Kato, Shigeaki -- Miyazono, Kohei -- England -- Nature. 2009 Jul 23;460(7254):529-33. doi: 10.1038/nature08199.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Pathology, Graduate School of Medicine, University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113-0033, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19626115" target="_blank"〉PubMed〈/a〉

    Human DAZL, DAZ and BOULE genes modulate primordial germ-cell and haploid gamete formation (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-10-30
    Description: The leading cause of infertility in men and women is quantitative and qualitative defects in human germ-cell (oocyte and sperm) development. Yet, it has not been possible to examine the unique developmental genetics of human germ-cell formation and differentiation owing to inaccessibility of germ cells during fetal development. Although several studies have shown that germ cells can be differentiated from mouse and human embryonic stem cells, human germ cells differentiated in these studies generally did not develop beyond the earliest stages. Here we used a germ-cell reporter to quantify and isolate primordial germ cells derived from both male and female human embryonic stem cells. By silencing and overexpressing genes that encode germ-cell-specific cytoplasmic RNA-binding proteins (not transcription factors), we modulated human germ-cell formation and developmental progression. We observed that human DAZL (deleted in azoospermia-like) functions in primordial germ-cell formation, whereas closely related genes DAZ and BOULE (also called BOLL) promote later stages of meiosis and development of haploid gametes. These results are significant to the generation of gametes for future basic science and potential clinical applications.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3133736/" 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/PMC3133736/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kee, Kehkooi -- Angeles, Vanessa T -- Flores, Martha -- Nguyen, Ha Nam -- Reijo Pera, Renee A -- R01 HD047721/HD/NICHD NIH HHS/ -- R01 HD047721-06/HD/NICHD NIH HHS/ -- R01HD047721/HD/NICHD NIH HHS/ -- U54 HD055764/HD/NICHD NIH HHS/ -- U54 HD055764-015755/HD/NICHD NIH HHS/ -- U54HD055764/HD/NICHD NIH HHS/ -- England -- Nature. 2009 Nov 12;462(7270):222-5. doi: 10.1038/nature08562.

    Crystal structure of the ATP-gated P2X(4) ion channel in the closed state (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-07-31
    Description: P2X receptors are cation-selective ion channels gated by extracellular ATP, and are implicated in diverse physiological processes, from synaptic transmission to inflammation to the sensing of taste and pain. Because P2X receptors are not related to other ion channel proteins of known structure, there is at present no molecular foundation for mechanisms of ligand-gating, allosteric modulation and ion permeation. Here we present crystal structures of the zebrafish P2X(4) receptor in its closed, resting state. The chalice-shaped, trimeric receptor is knit together by subunit-subunit contacts implicated in ion channel gating and receptor assembly. Extracellular domains, rich in beta-strands, have large acidic patches that may attract cations, through fenestrations, to vestibules near the ion channel. In the transmembrane pore, the 'gate' is defined by an approximately 8 A slab of protein. We define the location of three non-canonical, intersubunit ATP-binding sites, and suggest that ATP binding promotes subunit rearrangement and ion channel opening.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2720809/" 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/PMC2720809/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawate, Toshimitsu -- Michel, Jennifer Carlisle -- Birdsong, William T -- Gouaux, Eric -- U54 GM075026/GM/NIGMS NIH HHS/ -- U54 GM075026-04/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 Jul 30;460(7255):592-8. doi: 10.1038/nature08198.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health and Science University, 3181 Southwest Sam Jackson Park Road, Oregon 97239, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19641588" target="_blank"〉PubMed〈/a〉

    Increased mortality and AIDS-like immunopathology in wild chimpanzees infected with SIVcpz (2009)
    Nature Publishing Group (NPG)

    Description: African primates are naturally infected with over 40 different simian immunodeficiency viruses (SIVs), two of which have crossed the species barrier and generated human immunodeficiency virus types 1 and 2 (HIV-1 and HIV-2). Unlike the human viruses, however, SIVs do not generally cause acquired immunodeficiency syndrome (AIDS) in their natural hosts. Here we show that SIVcpz, the immediate precursor of HIV-1, is pathogenic in free-ranging chimpanzees. By following 94 members of two habituated chimpanzee communities in Gombe National Park, Tanzania, for over 9 years, we found a 10- to 16-fold higher age-corrected death hazard for SIVcpz-infected (n = 17) compared to uninfected (n = 77) chimpanzees. We also found that SIVcpz-infected females were less likely to give birth and had a higher infant mortality rate than uninfected females. Immunohistochemistry and in situ hybridization of post-mortem spleen and lymph node samples from three infected and two uninfected chimpanzees revealed significant CD4(+) T-cell depletion in all infected individuals, with evidence of high viral replication and extensive follicular dendritic cell virus trapping in one of them. One female, who died within 3 years of acquiring SIVcpz, had histopathological findings consistent with end-stage AIDS. These results indicate that SIVcpz, like HIV-1, is associated with progressive CD4(+) T-cell loss, lymphatic tissue destruction and premature death. These findings challenge the prevailing view that all natural SIV infections are non-pathogenic and suggest that SIVcpz has a substantial negative impact on the health, reproduction and lifespan of chimpanzees in the wild.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2872475/" 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/PMC2872475/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keele, Brandon F -- Jones, James Holland -- Terio, Karen A -- Estes, Jacob D -- Rudicell, Rebecca S -- Wilson, Michael L -- Li, Yingying -- Learn, Gerald H -- Beasley, T Mark -- Schumacher-Stankey, Joann -- Wroblewski, Emily -- Mosser, Anna -- Raphael, Jane -- Kamenya, Shadrack -- Lonsdorf, Elizabeth V -- Travis, Dominic A -- Mlengeya, Titus -- Kinsel, Michael J -- Else, James G -- Silvestri, Guido -- Goodall, Jane -- Sharp, Paul M -- Shaw, George M -- Pusey, Anne E -- Hahn, Beatrice H -- HHSN266200400088C/PHS HHS/ -- P30 AI 27767/AI/NIAID NIH HHS/ -- P30 AI027767/AI/NIAID NIH HHS/ -- P30 AI027767-21A17134/AI/NIAID NIH HHS/ -- R01 AI058715/AI/NIAID NIH HHS/ -- R01 AI058715-06A1/AI/NIAID NIH HHS/ -- R01 AI50529/AI/NIAID NIH HHS/ -- R01 AI58715/AI/NIAID NIH HHS/ -- R37 AI050529/AI/NIAID NIH HHS/ -- R37 AI050529-06A1/AI/NIAID NIH HHS/ -- RR-00165/RR/NCRR NIH HHS/ -- T32 GM008111/GM/NIGMS NIH HHS/ -- U19 AI067854/AI/NIAID NIH HHS/ -- U19 AI067854-059010/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 Jul 23;460(7254):515-9. doi: 10.1038/nature08200.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Alabama at Birmingham, Birmingham, Alabama 35294, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19626114" target="_blank"〉PubMed〈/a〉

    CBP/p300-mediated acetylation of histone H3 on lysine 56 (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-03-10
    Description: Acetylation within the globular core domain of histone H3 on lysine 56 (H3K56) has recently been shown to have a critical role in packaging DNA into chromatin following DNA replication and repair in budding yeast. However, the function or occurrence of this specific histone mark has not been studied in multicellular eukaryotes, mainly because the Rtt109 enzyme that is known to mediate acetylation of H3K56 (H3K56ac) is fungal-specific. Here we demonstrate that the histone acetyl transferase CBP (also known as Nejire) in flies and CBP and p300 (Ep300) in humans acetylate H3K56, whereas Drosophila Sir2 and human SIRT1 and SIRT2 deacetylate H3K56ac. The histone chaperones ASF1A in humans and Asf1 in Drosophila are required for acetylation of H3K56 in vivo, whereas the histone chaperone CAF-1 (chromatin assembly factor 1) in humans and Caf1 in Drosophila are required for the incorporation of histones bearing this mark into chromatin. We show that, in response to DNA damage, histones bearing acetylated K56 are assembled into chromatin in Drosophila and human cells, forming foci that colocalize with sites of DNA repair. Furthermore, acetylation of H3K56 is increased in multiple types of cancer, correlating with increased levels of ASF1A in these tumours. Our identification of multiple proteins regulating the levels of H3K56 acetylation in metazoans will allow future studies of this critical and unique histone modification that couples chromatin assembly to DNA synthesis, cell proliferation and cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756583/" 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/PMC2756583/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Das, Chandrima -- Lucia, M Scott -- Hansen, Kirk C -- Tyler, Jessica K -- CA95641/CA/NCI NIH HHS/ -- GM64475/GM/NIGMS NIH HHS/ -- R01 CA095641/CA/NCI NIH HHS/ -- R01 CA095641-07/CA/NCI NIH HHS/ -- R01 GM064475/GM/NIGMS NIH HHS/ -- R01 GM064475-07/GM/NIGMS NIH HHS/ -- England -- Nature. 2009 May 7;459(7243):113-7. doi: 10.1038/nature07861.

    Riboflavin kinase couples TNF receptor 1 to NADPH oxidase (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-07-31
    Description: Reactive oxygen species (ROS) produced by NADPH oxidase function as defence and signalling molecules related to innate immunity and various cellular responses. The activation of NADPH oxidase in response to plasma membrane receptor activation depends on the phosphorylation of cytoplasmic oxidase subunits, their translocation to membranes and the assembly of all NADPH oxidase components. Tumour necrosis factor (TNF) is a prominent stimulus of ROS production, but the molecular mechanisms by which TNF activates NADPH oxidase are poorly understood. Here we identify riboflavin kinase (RFK, formerly known as flavokinase) as a previously unrecognized TNF-receptor-1 (TNFR1)-binding protein that physically and functionally couples TNFR1 to NADPH oxidase. In mouse and human cells, RFK binds to both the TNFR1-death domain and to p22(phox), the common subunit of NADPH oxidase isoforms. RFK-mediated bridging of TNFR1 and p22(phox) is a prerequisite for TNF-induced but not for Toll-like-receptor-induced ROS production. Exogenous flavin mononucleotide or FAD was able to substitute fully for TNF stimulation of NADPH oxidase in RFK-deficient cells. RFK is rate-limiting in the synthesis of FAD, an essential prosthetic group of NADPH oxidase. The results suggest that TNF, through the activation of RFK, enhances the incorporation of FAD in NADPH oxidase enzymes, a critical step for the assembly and activation of NADPH oxidase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yazdanpanah, Benjamin -- Wiegmann, Katja -- Tchikov, Vladimir -- Krut, Oleg -- Pongratz, Carola -- Schramm, Michael -- Kleinridders, Andre -- Wunderlich, Thomas -- Kashkar, Hamid -- Utermohlen, Olaf -- Bruning, Jens C -- Schutze, Stefan -- Kronke, Martin -- England -- Nature. 2009 Aug 27;460(7259):1159-63. doi: 10.1038/nature08206.

    Predicting new molecular targets for known drugs (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-03
    Description: Although drugs are intended to be selective, at least some bind to several physiological targets, explaining side effects and efficacy. Because many drug-target combinations exist, it would be useful to explore possible interactions computationally. Here we compared 3,665 US Food and Drug Administration (FDA)-approved and investigational drugs against hundreds of targets, defining each target by its ligands. Chemical similarities between drugs and ligand sets predicted thousands of unanticipated associations. Thirty were tested experimentally, including the antagonism of the beta(1) receptor by the transporter inhibitor Prozac, the inhibition of the 5-hydroxytryptamine (5-HT) transporter by the ion channel drug Vadilex, and antagonism of the histamine H(4) receptor by the enzyme inhibitor Rescriptor. Overall, 23 new drug-target associations were confirmed, five of which were potent (〈100 nM). The physiological relevance of one, the drug N,N-dimethyltryptamine (DMT) on serotonergic receptors, was confirmed in a knockout mouse. The chemical similarity approach is systematic and comprehensive, and may suggest side-effects and new indications for many drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2784146/" 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/PMC2784146/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keiser, Michael J -- Setola, Vincent -- Irwin, John J -- Laggner, Christian -- Abbas, Atheir I -- Hufeisen, Sandra J -- Jensen, Niels H -- Kuijer, Michael B -- Matos, Roberto C -- Tran, Thuy B -- Whaley, Ryan -- Glennon, Richard A -- Hert, Jerome -- Thomas, Kelan L H -- Edwards, Douglas D -- Shoichet, Brian K -- Roth, Bryan L -- R01 DA017204/DA/NIDA NIH HHS/ -- R01 DA017204-04/DA/NIDA NIH HHS/ -- R01 DA017204-05/DA/NIDA NIH HHS/ -- R01 MH061887/MH/NIMH NIH HHS/ -- R01 MH061887-09/MH/NIMH NIH HHS/ -- R01 MH061887-10/MH/NIMH NIH HHS/ -- U19 MH082441/MH/NIMH NIH HHS/ -- U19 MH082441-01/MH/NIMH NIH HHS/ -- U19 MH082441-010001/MH/NIMH NIH HHS/ -- U19 MH082441-019002/MH/NIMH NIH HHS/ -- U19 MH082441-019003/MH/NIMH NIH HHS/ -- U19 MH082441-02/MH/NIMH NIH HHS/ -- U19 MH082441-020001/MH/NIMH NIH HHS/ -- U19 MH082441-029002/MH/NIMH NIH HHS/ -- U19 MH082441-03/MH/NIMH NIH HHS/ -- U19 MH082441-030001/MH/NIMH NIH HHS/ -- U19 MH082441-039002/MH/NIMH NIH HHS/ -- England -- Nature. 2009 Nov 12;462(7270):175-81. doi: 10.1038/nature08506.

    Changes of mind in decision-making (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-08-21
    Description: A decision is a commitment to a proposition or plan of action based on evidence and the expected costs and benefits associated with the outcome. Progress in a variety of fields has led to a quantitative understanding of the mechanisms that evaluate evidence and reach a decision. Several formalisms propose that a representation of noisy evidence is evaluated against a criterion to produce a decision. Without additional evidence, however, these formalisms fail to explain why a decision-maker would change their mind. Here we extend a model, developed to account for both the timing and the accuracy of the initial decision, to explain subsequent changes of mind. Subjects made decisions about a noisy visual stimulus, which they indicated by moving a handle. Although they received no additional information after initiating their movement, their hand trajectories betrayed a change of mind in some trials. We propose that noisy evidence is accumulated over time until it reaches a criterion level, or bound, which determines the initial decision, and that the brain exploits information that is in the processing pipeline when the initial decision is made to subsequently either reverse or reaffirm the initial decision. The model explains both the frequency of changes of mind as well as their dependence on both task difficulty and whether the initial decision was accurate or erroneous. The theoretical and experimental findings advance the understanding of decision-making to the highly flexible and cognitive acts of vacillation and self-correction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875179/" 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/PMC2875179/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Resulaj, Arbora -- Kiani, Roozbeh -- Wolpert, Daniel M -- Shadlen, Michael N -- 077730/Wellcome Trust/United Kingdom -- EY11378/EY/NEI NIH HHS/ -- Howard Hughes Medical Institute/ -- Wellcome Trust/United Kingdom -- England -- Nature. 2009 Sep 10;461(7261):263-6. doi: 10.1038/nature08275.

    Publication Date: 2009-12-04
    Description: The ability to produce stem cells by induced pluripotency (iPS reprogramming) has rekindled an interest in earlier studies showing that transcription factors can directly convert specialized cells from one lineage to another. Lineage reprogramming has become a powerful tool to study cell fate choice during differentiation, akin to inducing mutations for the discovery of gene functions. The lessons learnt provide a rubric for how cells may be manipulated for therapeutic purposes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graf, Thomas -- Enver, Tariq -- MC_U137973817/Medical Research Council/United Kingdom -- England -- Nature. 2009 Dec 3;462(7273):587-94. doi: 10.1038/nature08533.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Genomic Regulation and ICREA, 08003 Barcelona, Spain. thomas.graf@crg.es〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19956253" target="_blank"〉PubMed〈/a〉

    CCR3 is a target for age-related macular degeneration diagnosis and therapy (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-06-16
    Description: Age-related macular degeneration (AMD), a leading cause of blindness worldwide, is as prevalent as cancer in industrialized nations. Most blindness in AMD results from invasion of the retina by choroidal neovascularisation (CNV). Here we show that the eosinophil/mast cell chemokine receptor CCR3 is specifically expressed in choroidal neovascular endothelial cells in humans with AMD, and that despite the expression of its ligands eotaxin-1, -2 and -3, neither eosinophils nor mast cells are present in human CNV. Genetic or pharmacological targeting of CCR3 or eotaxins inhibited injury-induced CNV in mice. CNV suppression by CCR3 blockade was due to direct inhibition of endothelial cell proliferation, and was uncoupled from inflammation because it occurred in mice lacking eosinophils or mast cells, and was independent of macrophage and neutrophil recruitment. CCR3 blockade was more effective at reducing CNV than vascular endothelial growth factor A (VEGF-A) neutralization, which is in clinical use at present, and, unlike VEGF-A blockade, is not toxic to the mouse retina. In vivo imaging with CCR3-targeting quantum dots located spontaneous CNV invisible to standard fluorescein angiography in mice before retinal invasion. CCR3 targeting might reduce vision loss due to AMD through early detection and therapeutic angioinhibition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2712122/" 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/PMC2712122/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takeda, Atsunobu -- Baffi, Judit Z -- Kleinman, Mark E -- Cho, Won Gil -- Nozaki, Miho -- Yamada, Kiyoshi -- Kaneko, Hiroki -- Albuquerque, Romulo J C -- Dridi, Sami -- Saito, Kuniharu -- Raisler, Brian J -- Budd, Steven J -- Geisen, Pete -- Munitz, Ariel -- Ambati, Balamurali K -- Green, Martha G -- Ishibashi, Tatsuro -- Wright, John D -- Humbles, Alison A -- Gerard, Craig J -- Ogura, Yuichiro -- Pan, Yuzhen -- Smith, Justine R -- Grisanti, Salvatore -- Hartnett, M Elizabeth -- Rothenberg, Marc E -- Ambati, Jayakrishna -- AI039759/AI/NIAID NIH HHS/ -- AI45898/AI/NIAID NIH HHS/ -- DK076893/DK/NIDDK NIH HHS/ -- EY010572/EY/NEI NIH HHS/ -- EY015130/EY/NEI NIH HHS/ -- EY015422/EY/NEI NIH HHS/ -- EY017011/EY/NEI NIH HHS/ -- EY017182/EY/NEI NIH HHS/ -- EY017950/EY/NEI NIH HHS/ -- EY018350/EY/NEI NIH HHS/ -- EY018836/EY/NEI NIH HHS/ -- R01 DK076893/DK/NIDDK NIH HHS/ -- R01 EY015422/EY/NEI NIH HHS/ -- R01 EY015422-04/EY/NEI NIH HHS/ -- R01 EY018350/EY/NEI NIH HHS/ -- R01 EY018350-02/EY/NEI NIH HHS/ -- R01 EY018836/EY/NEI NIH HHS/ -- R01 EY018836-02/EY/NEI NIH HHS/ -- England -- Nature. 2009 Jul 9;460(7252):225-30. doi: 10.1038/nature08151.

    Travelling-wave nuclear magnetic resonance (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-02-20
    Description: Nuclear magnetic resonance (NMR) is one of the most versatile experimental methods in chemistry, physics and biology, providing insight into the structure and dynamics of matter at the molecular scale. Its imaging variant-magnetic resonance imaging (MRI)-is widely used to examine the anatomy, physiology and metabolism of the human body. NMR signal detection is traditionally based on Faraday induction in one or multiple radio-frequency resonators that are brought into close proximity with the sample. Alternative principles involving structured-material flux guides, superconducting quantum interference devices, atomic magnetometers, Hall probes or magnetoresistive elements have been explored. However, a common feature of all NMR implementations until now is that they rely on close coupling between the detector and the object under investigation. Here we show that NMR can also be excited and detected by long-range interaction, relying on travelling radio-frequency waves sent and received by an antenna. One benefit of this approach is more uniform coverage of samples that are larger than the wavelength of the NMR signal-an important current issue in MRI of humans at very high magnetic fields. By allowing a significant distance between the probe and the sample, travelling-wave interaction also introduces new possibilities in the design of NMR experiments and systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brunner, David O -- De Zanche, Nicola -- Frohlich, Jurg -- Paska, Jan -- Pruessmann, Klaas P -- England -- Nature. 2009 Feb 19;457(7232):994-8. doi: 10.1038/nature07752.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Biomedical Engineering, University of Zurich and ETH Zurich, Gloriastrasse 35, 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19225521" target="_blank"〉PubMed〈/a〉

    Human ISL1 heart progenitors generate diverse multipotent cardiovascular cell lineages (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-07-03
    Description: The generation and expansion of diverse cardiovascular cell lineages is a critical step during human cardiogenesis, with major implications for congenital heart disease. Unravelling the mechanisms for the diversification of human heart cell lineages has been hampered by the lack of genetic tools to purify early cardiac progenitors and define their developmental potential. Recent studies in the mouse embryo have identified a multipotent cardiac progenitor that contributes to all of the major cell types in the murine heart. In contrast to murine development, human cardiogenesis has a much longer onset of heart cell lineage diversification and expansion, suggesting divergent pathways. Here we identify a diverse set of human fetal ISL1(+) cardiovascular progenitors that give rise to the cardiomyocyte, smooth muscle and endothelial cell lineages. Using two independent transgenic and gene-targeting approaches in human embryonic stem cell lines, we show that purified ISL1(+) primordial progenitors are capable of self-renewal and expansion before differentiation into the three major cell types in the heart. These results lay the foundation for the generation of human model systems for cardiovascular disease and novel approaches for human regenerative cardiovascular medicine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bu, Lei -- Jiang, Xin -- Martin-Puig, Silvia -- Caron, Leslie -- Zhu, Shenjun -- Shao, Ying -- Roberts, Drucilla J -- Huang, Paul L -- Domian, Ibrahim J -- Chien, Kenneth R -- England -- Nature. 2009 Jul 2;460(7251):113-7. doi: 10.1038/nature08191.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cardiovascular Research Center, Massachusetts General Hospital, Charles River Plaza/CPZN 3208, 185 Cambridge Street, Boston, Massachusetts 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19571884" target="_blank"〉PubMed〈/a〉

    Reconstruction of the history of anthropogenic CO(2) concentrations in the ocean (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-20
    Description: The release of fossil fuel CO(2) to the atmosphere by human activity has been implicated as the predominant cause of recent global climate change. The ocean plays a crucial role in mitigating the effects of this perturbation to the climate system, sequestering 20 to 35 per cent of anthropogenic CO(2) emissions. Although much progress has been made in recent years in understanding and quantifying this sink, considerable uncertainties remain as to the distribution of anthropogenic CO(2) in the ocean, its rate of uptake over the industrial era, and the relative roles of the ocean and terrestrial biosphere in anthropogenic CO(2) sequestration. Here we address these questions by presenting an observationally based reconstruction of the spatially resolved, time-dependent history of anthropogenic carbon in the ocean over the industrial era. Our approach is based on the recognition that the transport of tracers in the ocean can be described by a Green's function, which we estimate from tracer data using a maximum entropy deconvolution technique. Our results indicate that ocean uptake of anthropogenic CO(2) has increased sharply since the 1950s, with a small decline in the rate of increase in the last few decades. We estimate the inventory and uptake rate of anthropogenic CO(2) in 2008 at 140 +/- 25 Pg C and 2.3 +/- 0.6 Pg C yr(-1), respectively. We find that the Southern Ocean is the primary conduit by which this CO(2) enters the ocean (contributing over 40 per cent of the anthropogenic CO(2) inventory in the ocean in 2008). Our results also suggest that the terrestrial biosphere was a source of CO(2) until the 1940s, subsequently turning into a sink. Taken over the entire industrial period, and accounting for uncertainties, we estimate that the terrestrial biosphere has been anywhere from neutral to a net source of CO(2), contributing up to half as much CO(2) as has been taken up by the ocean over the same period.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Khatiwala, S -- Primeau, F -- Hall, T -- England -- Nature. 2009 Nov 19;462(7271):346-9. doi: 10.1038/nature08526.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lamont-Doherty Earth Observatory of Columbia University, Palisades, New York 10964, USA. spk@ldeo.columbia.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19924213" target="_blank"〉PubMed〈/a〉

    JAK2 phosphorylates histone H3Y41 and excludes HP1alpha from chromatin (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-09-29
    Description: Activation of Janus kinase 2 (JAK2) by chromosomal translocations or point mutations is a frequent event in haematological malignancies. JAK2 is a non-receptor tyrosine kinase that regulates several cellular processes by inducing cytoplasmic signalling cascades. Here we show that human JAK2 is present in the nucleus of haematopoietic cells and directly phosphorylates Tyr 41 (Y41) on histone H3. Heterochromatin protein 1alpha (HP1alpha), but not HP1beta, specifically binds to this region of H3 through its chromo-shadow domain. Phosphorylation of H3Y41 by JAK2 prevents this binding. Inhibition of JAK2 activity in human leukaemic cells decreases both the expression of the haematopoietic oncogene lmo2 and the phosphorylation of H3Y41 at its promoter, while simultaneously increasing the binding of HP1alpha at the same site. Tauhese results identify a previously unrecognized nuclear role for JAK2 in the phosphorylation of H3Y41 and reveal a direct mechanistic link between two genes, jak2 and lmo2, involved in normal haematopoiesis and leukaemia.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3785147/" 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/PMC3785147/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dawson, Mark A -- Bannister, Andrew J -- Gottgens, Berthold -- Foster, Samuel D -- Bartke, Till -- Green, Anthony R -- Kouzarides, Tony -- 089957/Wellcome Trust/United Kingdom -- 12765/Cancer Research UK/United Kingdom -- G0800784/Medical Research Council/United Kingdom -- MC_UP_1102/2/Medical Research Council/United Kingdom -- Cancer Research UK/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2009 Oct 8;461(7265):819-22. doi: 10.1038/nature08448.

    Formyl peptide receptor-like proteins are a novel family of vomeronasal chemosensors (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-04-24
    Description: Mammals rely heavily on olfaction to interact adequately with each other and with their environment. They make use of seven-transmembrane G-protein-coupled receptors to identify odorants and pheromones. These receptors are present on dendrites of olfactory sensory neurons located in the main olfactory or vomeronasal sensory epithelia, and pertain to the odorant, trace amine-associated receptor and vomeronasal type 1 (ref. 4) or 2 (refs 5-7) receptor superfamilies. Whether these four sensor classes represent the complete olfactory molecular repertoire used by mammals to make sense of the outside world is unknown. Here we report the expression of formyl peptide receptor-related genes by vomeronasal sensory neurons, in multiple mammalian species. Similar to the four known olfactory receptor gene classes, these genes encode seven-transmembrane proteins, and are characterized by monogenic transcription and a punctate expression pattern in the sensory neuroepithelium. In vitro expression of mouse formyl peptide receptor-like 1, 3, 4, 6 and 7 provides sensitivity to disease/inflammation-related ligands. Establishing an in situ approach that combines whole-mount vomeronasal preparations with dendritic calcium imaging in the intact neuroepithelium, we show neuronal responses to the same molecules, which therefore represent a new class of vomeronasal agonists. Taken together, these results suggest that formyl peptide receptor-like proteins have an olfactory function associated with the identification of pathogens, or of pathogenic states.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Riviere, Stephane -- Challet, Ludivine -- Fluegge, Daniela -- Spehr, Marc -- Rodriguez, Ivan -- England -- Nature. 2009 May 28;459(7246):574-7. doi: 10.1038/nature08029.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology and Animal Biology, and National Center of Competence Frontiers in Genetics, University of Geneva, 1205 Geneva, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19387439" target="_blank"〉PubMed〈/a〉

    Direct reprogramming of human neural stem cells by OCT4 (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-09-01
    Description: Induced pluripotent stem (iPS) cells have been generated from mouse and human somatic cells by ectopic expression of four transcription factors (OCT4 (also called POU5F1), SOX2, c-Myc and KLF4). We previously reported that Oct4 alone is sufficient to reprogram directly adult mouse neural stem cells to iPS cells. Here we report the generation of one-factor human iPS cells from human fetal neural stem cells (one-factor (1F) human NiPS cells) by ectopic expression of OCT4 alone. One-factor human NiPS cells resemble human embryonic stem cells in global gene expression profiles, epigenetic status, as well as pluripotency in vitro and in vivo. These findings demonstrate that the transcription factor OCT4 is sufficient to reprogram human neural stem cells to pluripotency. One-factor iPS cell generation will advance the field further towards understanding reprogramming and generating patient-specific pluripotent stem cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Jeong Beom -- Greber, Boris -- Arauzo-Bravo, Marcos J -- Meyer, Johann -- Park, Kook In -- Zaehres, Holm -- Scholer, Hans R -- England -- Nature. 2009 Oct 1;461(7264):649-3. doi: 10.1038/nature08436.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Molecular Biomedicine, Department of Cell and Developmental Biology, Rontgenstrasse 20, 48149 Munster, NRW, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19718018" target="_blank"〉PubMed〈/a〉

    Publication Date: 2009-05-02
    Description: The principal tumour-suppressor protein, p53, accumulates in cells in response to DNA damage, oncogene activation and other stresses. It acts as a nuclear transcription factor that transactivates genes involved in apoptosis, cell cycle regulation and numerous other processes. An emerging area of research unravels additional activities of p53 in the cytoplasm, where it triggers apoptosis and inhibits autophagy. These previously unknown functions contribute to the mission of p53 as a tumour suppressor.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2814168/" 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/PMC2814168/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, Douglas R -- Kroemer, Guido -- P01 CA069381/CA/NCI NIH HHS/ -- P01 CA069381-140010/CA/NCI NIH HHS/ -- R01 AI040646/AI/NIAID NIH HHS/ -- R01 AI040646-14/AI/NIAID NIH HHS/ -- R01 AI044828/AI/NIAID NIH HHS/ -- R01 AI044828-12/AI/NIAID NIH HHS/ -- R01 AI047891/AI/NIAID NIH HHS/ -- R01 AI047891-11/AI/NIAID NIH HHS/ -- R37 GM052735/GM/NIGMS NIH HHS/ -- R37 GM052735-19/GM/NIGMS NIH HHS/ -- England -- Nature. 2009 Apr 30;458(7242):1127-30. doi: 10.1038/nature07986.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, St Jude Children's Research Hospital, Memphis, Tennessee 38105, USA. douglas.green@stjude.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19407794" target="_blank"〉PubMed〈/a〉

    A highly annotated whole-genome sequence of a Korean individual (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-07-10
    Description: Recent advances in sequencing technologies have initiated an era of personal genome sequences. To date, human genome sequences have been reported for individuals with ancestry in three distinct geographical regions: a Yoruba African, two individuals of northwest European origin, and a person from China. Here we provide a highly annotated, whole-genome sequence for a Korean individual, known as AK1. The genome of AK1 was determined by an exacting, combined approach that included whole-genome shotgun sequencing (27.8x coverage), targeted bacterial artificial chromosome sequencing, and high-resolution comparative genomic hybridization using custom microarrays featuring more than 24 million probes. Alignment to the NCBI reference, a composite of several ethnic clades, disclosed nearly 3.45 million single nucleotide polymorphisms (SNPs), including 10,162 non-synonymous SNPs, and 170,202 deletion or insertion polymorphisms (indels). SNP and indel densities were strongly correlated genome-wide. Applying very conservative criteria yielded highly reliable copy number variants for clinical considerations. Potential medical phenotypes were annotated for non-synonymous SNPs, coding domain indels, and structural variants. The integration of several human whole-genome sequences derived from several ethnic groups will assist in understanding genetic ancestry, migration patterns and population bottlenecks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2860965/" 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/PMC2860965/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Jong-Il -- Ju, Young Seok -- Park, Hansoo -- Kim, Sheehyun -- Lee, Seonwook -- Yi, Jae-Hyuk -- Mudge, Joann -- Miller, Neil A -- Hong, Dongwan -- Bell, Callum J -- Kim, Hye-Sun -- Chung, In-Soon -- Lee, Woo-Chung -- Lee, Ji-Sun -- Seo, Seung-Hyun -- Yun, Ji-Young -- Woo, Hyun Nyun -- Lee, Heewook -- Suh, Dongwhan -- Lee, Seungbok -- Kim, Hyun-Jin -- Yavartanoo, Maryam -- Kwak, Minhye -- Zheng, Ying -- Lee, Mi Kyeong -- Park, Hyunjun -- Kim, Jeong Yeon -- Gokcumen, Omer -- Mills, Ryan E -- Zaranek, Alexander Wait -- Thakuria, Joseph -- Wu, Xiaodi -- Kim, Ryan W -- Huntley, Jim J -- Luo, Shujun -- Schroth, Gary P -- Wu, Thomas D -- Kim, HyeRan -- Yang, Kap-Seok -- Park, Woong-Yang -- Kim, Hyungtae -- Church, George M -- Lee, Charles -- Kingsmore, Stephen F -- Seo, Jeong-Sun -- HG004221/HG/NHGRI NIH HHS/ -- P20 RR016480/RR/NCRR NIH HHS/ -- P20 RR016480-08/RR/NCRR NIH HHS/ -- RR016480/RR/NCRR NIH HHS/ -- U01 AI066569/AI/NIAID NIH HHS/ -- U01 AI066569-04/AI/NIAID NIH HHS/ -- U19 HD077693/HD/NICHD NIH HHS/ -- England -- Nature. 2009 Aug 20;460(7258):1011-5. doi: 10.1038/nature08211.

    Requirement for NF-kappaB signalling in a mouse model of lung adenocarcinoma (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-10-23
    Description: NF-kappaB transcription factors function as crucial regulators of inflammatory and immune responses as well as of cell survival. They have also been implicated in cellular transformation and tumorigenesis. However, despite extensive biochemical characterization of NF-kappaB signalling during the past twenty years, the requirement for NF-kappaB in tumour development in vivo, particularly in solid tumours, is not completely understood. Here we show that the NF-kappaB pathway is required for the development of tumours in a mouse model of lung adenocarcinoma. Concomitant loss of p53 (also known as Trp53) and expression of oncogenic Kras(G12D) resulted in NF-kappaB activation in primary mouse embryonic fibroblasts. Conversely, in lung tumour cell lines expressing Kras(G12D) and lacking p53, p53 restoration led to NF-kappaB inhibition. Furthermore, the inhibition of NF-kappaB signalling induced apoptosis in p53-null lung cancer cell lines. Inhibition of the pathway in lung tumours in vivo, from the time of tumour initiation or after tumour progression, resulted in significantly reduced tumour development. Together, these results indicate a critical function for NF-kappaB signalling in lung tumour development and, further, that this requirement depends on p53 status. These findings also provide support for the development of NF-kappaB inhibitory drugs as targeted therapies for the treatment of patients with defined mutations in Kras and p53.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2780341/" 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/PMC2780341/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meylan, Etienne -- Dooley, Alison L -- Feldser, David M -- Shen, Lynn -- Turk, Erin -- Ouyang, Chensi -- Jacks, Tyler -- P30 CA014051/CA/NCI NIH HHS/ -- P30 CA014051-37/CA/NCI NIH HHS/ -- P30 CA014051-38/CA/NCI NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 Nov 5;462(7269):104-7. doi: 10.1038/nature08462.

    CtIP-BRCA1 modulates the choice of DNA double-strand-break repair pathway throughout the cell cycle (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-04-10
    Description: The repair of DNA double-strand breaks (DSBs) is tightly regulated during the cell cycle. In G1 phase, the absence of a sister chromatid means that repair of DSBs occurs through non-homologous end-joining or microhomology-mediated end-joining (MMEJ). These pathways often involve loss of DNA sequences at the break site and are therefore error-prone. In late S and G2 phases, even though DNA end-joining pathways remain functional, there is an increase in repair of DSBs by homologous recombination, which is mostly error-free. Consequently, the relative contribution of these different pathways to DSB repair in the cell cycle has a large influence on the maintenance of genetic integrity. It has remained unknown how DSBs are directed for repair by different, potentially competing, repair pathways. Here we identify a role for CtIP (also known as RBBP8) in this process in the avian B-cell line DT40. We establish that CtIP is required not only for repair of DSBs by homologous recombination in S/G2 phase but also for MMEJ in G1. The function of CtIP in homologous recombination, but not MMEJ, is dependent on the phosphorylation of serine residue 327 and recruitment of BRCA1. Cells expressing CtIP protein that cannot be phosphorylated at serine 327 are specifically defective in homologous recombination and have a decreased level of single-stranded DNA after DNA damage, whereas MMEJ remains unaffected. Our data support a model in which phosphorylation of serine 327 of CtIP as cells enter S phase and the recruitment of BRCA1 functions as a molecular switch to shift the balance of DSB repair from error-prone DNA end-joining to error-free homologous recombination.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2857324/" 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/PMC2857324/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yun, Maximina H -- Hiom, Kevin -- MC_U105184300/Medical Research Council/United Kingdom -- U.1051.03.005(78826)/Medical Research Council/United Kingdom -- England -- Nature. 2009 May 21;459(7245):460-3. doi: 10.1038/nature07955.

    Design of protein-interaction specificity gives selective bZIP-binding peptides (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-04-17
    Description: Interaction specificity is a required feature of biological networks and a necessary characteristic of protein or small-molecule reagents and therapeutics. The ability to alter or inhibit protein interactions selectively would advance basic and applied molecular science. Assessing or modelling interaction specificity requires treating multiple competing complexes, which presents computational and experimental challenges. Here we present a computational framework for designing protein-interaction specificity and use it to identify specific peptide partners for human basic-region leucine zipper (bZIP) transcription factors. Protein microarrays were used to characterize designed, synthetic ligands for all but one of 20 bZIP families. The bZIP proteins share strong sequence and structural similarities and thus are challenging targets to bind specifically. Nevertheless, many of the designs, including examples that bind the oncoproteins c-Jun, c-Fos and c-Maf (also called JUN, FOS and MAF, respectively), were selective for their targets over all 19 other families. Collectively, the designs exhibit a wide range of interaction profiles and demonstrate that human bZIPs have only sparsely sampled the possible interaction space accessible to them. Our computational method provides a way to systematically analyse trade-offs between stability and specificity and is suitable for use with many types of structure-scoring functions; thus, it may prove broadly useful as a tool for protein design.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2748673/" 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/PMC2748673/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grigoryan, Gevorg -- Reinke, Aaron W -- Keating, Amy E -- GM67681/GM/NIGMS NIH HHS/ -- R01 GM067681/GM/NIGMS NIH HHS/ -- R01 GM067681-04/GM/NIGMS NIH HHS/ -- R01 GM067681-05/GM/NIGMS NIH HHS/ -- England -- Nature. 2009 Apr 16;458(7240):859-64. doi: 10.1038/nature07885.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MIT Department of Biology, 77 Massachusetts Avenue, Cambridge, Massachusetts 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19370028" target="_blank"〉PubMed〈/a〉

    Chaperone-mediated pathway of proteasome regulatory particle assembly (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-05-05
    Description: The proteasome is a protease that controls diverse processes in eukaryotic cells. Its regulatory particle (RP) initiates the degradation of ubiquitin-protein conjugates by unfolding the substrate and translocating it into the proteasome core particle (CP) to be degraded. The RP has 19 subunits, and their pathway of assembly is not understood. Here we show that in the yeast Saccharomyces cerevisiae three proteins are found associated with RP but not with the RP-CP holoenzyme: Nas6, Rpn14 and Hsm3. Mutations in the corresponding genes confer proteasome loss-of-function phenotypes, despite their virtual absence from the holoenzyme. These effects result from deficient RP assembly. Thus, Nas6, Rpn14 and Hsm3 are RP chaperones. The RP contains six ATPases-the Rpt proteins-and each RP chaperone binds to the carboxy-terminal domain of a specific Rpt. We show in an accompanying study that RP assembly is templated through the Rpt C termini, apparently by their insertion into binding pockets in the CP. Thus, RP chaperones may regulate proteasome assembly by directly restricting the accessibility of Rpt C termini to the CP. In addition, competition between the RP chaperones and the CP for Rpt engagement may explain the release of RP chaperones as proteasomes mature.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2727592/" 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/PMC2727592/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roelofs, Jeroen -- Park, Soyeon -- Haas, Wilhelm -- Tian, Geng -- McAllister, Fiona E -- Huo, Ying -- Lee, Byung-Hoon -- Zhang, Fan -- Shi, Yigong -- Gygi, Steven P -- Finley, Daniel -- 5F32GM75737-2/GM/NIGMS NIH HHS/ -- GM043601/GM/NIGMS NIH HHS/ -- GM67945/GM/NIGMS NIH HHS/ -- R37 GM043601/GM/NIGMS NIH HHS/ -- R37 GM043601-19/GM/NIGMS NIH HHS/ -- England -- Nature. 2009 Jun 11;459(7248):861-5. doi: 10.1038/nature08063.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, 240 Longwood Avenue, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19412159" target="_blank"〉PubMed〈/a〉

    Cohesin acetylation speeds the replication fork (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-13
    Description: Cohesin not only links sister chromatids but also inhibits the transcriptional machinery's interaction with and movement along chromatin. In contrast, replication forks must traverse such cohesin-associated obstructions to duplicate the entire genome in S phase. How this occurs is unknown. Through single-molecule analysis, we demonstrate that the replication factor C (RFC)-CTF18 clamp loader (RFC(CTF18)) controls the velocity, spacing and restart activity of replication forks in human cells and is required for robust acetylation of cohesin's SMC3 subunit and sister chromatid cohesion. Unexpectedly, we discovered that cohesin acetylation itself is a central determinant of fork processivity, as slow-moving replication forks were found in cells lacking the Eco1-related acetyltransferases ESCO1 or ESCO2 (refs 8-10) (including those derived from Roberts' syndrome patients, in whom ESCO2 is biallelically mutated) and in cells expressing a form of SMC3 that cannot be acetylated. This defect was a consequence of cohesin's hyperstable interaction with two regulatory cofactors, WAPL and PDS5A (refs 12, 13); removal of either cofactor allowed forks to progress rapidly without ESCO1, ESCO2, or RFC(CTF18). Our results show a novel mechanism for clamp-loader-dependent fork progression, mediated by the post-translational modification and structural remodelling of the cohesin ring. Loss of this regulatory mechanism leads to the spontaneous accrual of DNA damage and may contribute to the abnormalities of the Roberts' syndrome cohesinopathy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2777716/" 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/PMC2777716/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Terret, Marie-Emilie -- Sherwood, Rebecca -- Rahman, Sadia -- Qin, Jun -- Jallepalli, Prasad V -- R01 CA107342/CA/NCI NIH HHS/ -- R01 CA107342-05/CA/NCI NIH HHS/ -- R01 GM094972/GM/NIGMS NIH HHS/ -- England -- Nature. 2009 Nov 12;462(7270):231-4. doi: 10.1038/nature08550.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology Program, Memorial Sloan-Kettering Cancer Center, 1275 York Avenue, New York, New York 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19907496" target="_blank"〉PubMed〈/a〉

    Description: The rapid turnover and exfoliation of mucosal epithelial cells provides an innate defence system against bacterial infection. Nevertheless, many pathogenic bacteria, including Shigella, are able to surmount exfoliation and colonize the epithelium efficiently. Here we show that the Shigella flexneri effector OspE (consisting of OspE1 and OspE2 proteins), which is highly conserved among enteropathogenic Escherichia coli, enterohaemorrhagic E. coli, Citrobacter rodentium and Salmonella strains, reinforces host cell adherence to the basement membrane by interacting with integrin-linked kinase (ILK). The number of focal adhesions was augmented along with membrane fraction ILK by ILK-OspE binding. The interaction between ILK and OspE increased cell surface levels of 1 integrin and suppressed phosphorylation of focal adhesion kinase and paxillin, which are required for rapid turnover of focal adhesion in cell motility. Nocodazole-washout-induced focal adhesion disassembly was blocked by expression of OspE. Polarized epithelial cells infected with a Shigella mutant lacking the ospE gene underwent more rapid cell detachment than cells infected with wild-type Shigella. Infection of guinea pig colons with Shigella corroborated the pivotal role of the OspE-ILK interaction in suppressing epithelial detachment, increasing bacterial cell-to-cell spreading, and promoting bacterial colonization. These results indicate that Shigella sustain their infectious foothold by using special tactics to prevent detachment of infected cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Minsoo -- Ogawa, Michinaga -- Fujita, Yukihiro -- Yoshikawa, Yuko -- Nagai, Takeshi -- Koyama, Tomohiro -- Nagai, Shinya -- Lange, Anika -- Fassler, Reinhard -- Sasakawa, Chihiro -- England -- Nature. 2009 May 28;459(7246):578-82. doi: 10.1038/nature07952.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Infectious Disease Control, International Research Center for Infectious Diseases, University of Tokyo, 4-6-1, Shirokanedai, Minato-ku, Tokyo 108-8639, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19489119" target="_blank"〉PubMed〈/a〉
