    Future Global Shocks : Improving Risk Governance (2011)
    Paris : OECD
    Details
    Keywords: risk assessment
    Description / Table of Contents: Recent global shocks, such as the 2008 financial crisis, have driven policy makers and industry strategists to re-examine how to prepare for and respond to events that can begin locally and propagate around the world with devastating effects on society and the economy. This report considers how the growing interconnectedness in the global economy could create the conditions and vectors for rapid and widespread disruptions. It looks at examples of hazards and threats that emerge from the financial world, cyberspace, biological systems and even the solar system, to reflect on what strategic capacities are called for to improve assessment, mapping, modelling, response and resilience to such large scale risks.

    Topics: Biology
    Notes: Abstract The quality of sediment was assessed in 46 sites in the delta of the rivers Rhine and Meuse (The Netherlands) by means of physical-chemical analysis, field observations on the macrobenthic community structure, accumulation studies and bioassays using Chironomus riparius, Daphnia magna and Photobacterium phosphoreum. The results of chemical analyses were classified using national criteria for sediment quality. Results of field studies and bioassays were classified using criteria derived from research in reference areas or based on data from literature. Risk assessment was carried out according to the sediment quality triad and by means of multi criteria analysis (MCA). The Triad approach was used to demonstrate causal relations between effects on the macrozoobenthos community structure, effects demonstrated in bioassays and sediment pollution. This was done by making a comparison of sediment contamination levels with toxicity data from literature for the test organisms of the bioassays. Using the MCA method, for each site a numerical value was derived for total environmental risk in the present situation, based on observed effects. In this way, a relative risk ranking of all sites was realized. The MCA values for the present situation were also compared with MCA scores based on estimated risks after remediation in 1995, in order to set priorities for sites where remediation is expected to cause a significant reduction in environmental risk. In most of the 46 sites studied so far, the macrofauna community was poorly developed, judged by a low number of benthic species, low abundances and a high dominance of species regarded as relatively tolerant to chemical pollution. In bioassays high sediment toxicity was demonstrated for 24 sites. Using the sediment quality triad approach, 25 sites were identified as areas where pollution can be held responsible for the effects observed in the field. From a comparison of contaminant concentrations in different types of food with maximum tolerable risk levels, and the application of a bioaccumulation model it was concluded that the sediment pollution also implies high risks for plant-, benthos- or fish-eating birds (secondary poisoning of top predators). In the Nieuwe Merwede highest MCA risk scores were found for shallow parts where highly polluted sediments are found. It is concluded that the sediment quality triad and the MCA provide additional information which can be used to establish priorities for remedial action. Based on an ecotoxicological evaluation of the improved quality of new sediments that will be deposited after removal of the polluted sediments in the Nieuwe Merwede, it is concluded that in this upstream part of the Rhine delta remedial action will be effective.

    Geophysical and geotechnical observations to assess the morphological risk in the Acqua Albule Basin sinkhole prone area (Rome, Italy): two case studies (2020)
    Details
    Publication Date: 2021-02-23
    Description: We present the results of multidisciplinary investigations of two significant sites, located in the Acque Albule Basin (AAB), 25 km Northeast of Rome (Italy). This basin has been interpreted as a transtensional structure, lying in the western margin of the Apennine range and affecting the Plio-Pleistocene sedimentary and volcanic sequences. During late Pleistocene times, AAB has been filled in with thermogenic travertine of variable thickness. Since historical time, lithoid travertine has been quarried, becoming the main building material during the Roman period (Lapis Tiburtinus). At present, the mining activity still represents the main economic resource of the region together with thermal baths. After the end of the II World War this area has experienced a strong urbanization and marshy lands were transformed into densely populated areas affected by subsidence and sinkhole phenomena. In order to characterize these environmental hazards from the geophysical and geotechnical point of view, we chose two test sites close to relevant anthropic infrastructures. Site A, located at the southern side of the Guidonia military airport and beside an important road; site B, a few kilometers South-East of site A, lies next to the Regina and Colonnelle Lakes and close to the Roma- Pescara railway. The former feature is a large sinkhole depression, hundreds of meters in width, characterized by ongoing subsidence, whereas the latter consists of two sinkholes actually acting as springs. Both sites lie in proximity of inferred faults, which would affect the AAB in the N-S and NE-SW– directions respectively. The aim of this study is to compare the two cases by collecting geological, geomorphological and geophysical parameters and thus testing the variable controlling their formation and development. We also extended the geophysical campaign in the surrounding area using a multidisciplinary approach to image both surface and subsurface features. We carried out stratigraphic and geomorphological survey, 2 and 3D Geoelectrical Tomography (ERT), differential GPS altimetry, gravity, magnetic, seismic, and soil gas measurements. Moreover, two drillings have been bored inside and outside the depression area of the Site A, reaching depths of 60 and 20 meter, respectively. Geotechnical parameters of the recovered stratigraphy were also measured by laboratory tests. In general, the approach we propose could provide key elements to recognize similar situations in sinkhole prone areas. Moreover, comparative analysis together with the monitoring of the A site can represent useful tools to understand the genesis and dynamics of phenomena and hopefully to forecast their evolution, particularly in the parts of the basin where active movements caused fractures and damages to buildings and infrastructures.

    A WebGis tool for seismic hazard scenarios and risk analysis (2010)
    Elsevier
    Details
    Publication Date: 2017-04-04
    Description: The WebGis development represents a natural answer to the growing requests for dissemination and use of geographical information data. WebGis originates from a combination of web technology and the Geographical Information System, which is a recognised technology that is mainly composed of data handling tools for storage, recovery, management and analysis of spatial data. Here, we illustrate two examples of seismic hazard and risk analysis through the WebGis system in terms of architecture and content. The first presents ground shaking scenarios associated with the repetition of the earthquake that struck the Lake of Garda area (northern Italy) in 2004. The second shows data and results of a more extensive analysis of seismic risk in the western part of the Liguria region (north-western Italy) for residential buildings, strategic structures and historic architecture. The adoption of a freeware application (ALOVMap) assures easy exportability of the WebGis structures for projects dealing with natural hazard evaluation.

    Description: An edited version of this paper was published by AGU. Copyright (2009) American Geophysical Union.
    Description: Despite volcanic risk having been defined quantitatively more than 30 years ago, this risk has been managed without being effectively measured. The recent substantial progress in quantifying eruption probability paves the way for a new era of rational science-based volcano risk management, based on what may be termed ‘‘volcanic risk metrics’’ (VRM). In this paper, we propose the basic principles of VRM, based on coupling probabilistic volcanic hazard assessment and eruption forecasting with cost-benefit analysis. The VRM strategy has the potential to rationalize decision making across a broad spectrum of volcanological questions. When should the call for evacuation be made? What early preparations should be made for a volcano crisis? Is it worthwhile waiting longer? What areas should be covered by an emergency plan? During unrest, what areas of a large volcanic field or caldera should be evacuated, and when? The VRM strategy has the paramount advantage of providing a set of quantitative and transparent rules that can be established well in advance of a crisis, optimizing and clarifying decision-making procedures. It enables volcanologists to apply all their scientific knowledge and observational information to assist authorities in quantifying the positive and negative risk implications of any decision.

    Mercury emissions and stable isotopic compositions at Vulcano Island (Italy) (2010)
    ELSEVIER
    Details
    Publication Date: 2017-04-04
    Description: Sampling and analyses methods for determining the stable isotopic compositions of Hg in an active volcanic system were tested and optimized at the volcanic complex of Vulcano (Aeolian Islands, Italy). Condensed gaseous fumarole Hg(fum) T , plume gaseous elemental Hg(g) 0 and plume particulate Hg(p) II were obtained at fumaroles F0, F5, F11, and FA. The average total Hg emissions, based on HgT/SO2 in condensed fumarolic gases and plumes, range from 2.5 to 10.1 kg y−1, in agreement with published values [Ferrara, R., Mazzolai, B., Lanzillotta, E., Nucaro, E., Pirrone, N., 2000. Volcanoes as emission sources of atmospheric mercury in the Mediterranean Basin. Sci. Total Environ. 259(1–3), 115–121; Aiuppa, A., Bagnato, E., Witt, M.L.I., Mather, T.A., Parello, F., Pyle, D.M., Martin, R.S., 2007. Real-time simultaneous detection of volcanic Hg and SO2 at La Fossa Crater, Vulcano (Aeolian Islands, Sicily). Geophys. Res. Lett. 34(L21307).]. Plume Hg(p) II increases with distance from the fumarole vent, at the expense of Hg(g) 0 and indicates significant in-plume oxidation and condensation of fumarole Hg(fum) T . Relative to the NIST SRM3133 Hg standard, the stable isotopic compositions of Hg are δ202Hg(fum) T =−0.74‰±0.18 (2SD, n=4) for condensed gaseous fumarole Hg(fum) T , δ202Hg(g) 0 =−1.74‰±0.36 (2SD, n=1) for plume gaseous elemental Hg(g) 0 at the F0 fumarole, and δ202Hg(p) II =−0.11‰±0.18 (2SD, n=4) for plume particulate Hg(p) II . The enrichment of Hg(p) II in the heavy isotopes and Hg(g) 0 in the light isotopes relative to the total condensed fumarolic Hg(fum) T gas complements the speciation data and demonstrates a gas-particle fractionation occurring after the gas expulsion inambient T° atmosphere. A first order Rayleigh equilibriumcondensation isotope fractionation model yields a fractionation factor αcond-gas of 1.00135±0.00058.

    A buried volcano in the Calabrian Arc (Italy) revealed by high‐resolution aeromagnetic data (2010)
    American Geophysical Union
    Details
    Publication Date: 2012-02-03
    Description: An edited version of this paper was published by AGU. Copyright (2010) American Geophysical Union.
    Description: Aeromagnetic data collected between the Aeolian volcanoes (southern Tyrrhenian Sea) and the Calabrian Arc (Italy) highlight a WNW‐ESE elongated positive magnetic anomaly centered on the Capo Vaticano morphological ridge (Tyrrhenian coast of Calabria), characterized by an apical, subcircular, flat surface. Results of forward and inverse modeling of the magnetic data show a 20 km long and 3–5 km wide magnetized body that extends from sea floor to about 3 km below sea level. The magnetic properties of this body are consistent with those of the medium to highly evolved volcanic rocks of the Aeolian Arc (i.e., dacites and rhyolites). In the Calabria mainland, widespread dacitic to rhyolitic pumices with calc‐alkaline affinity of Pleistocene age (1–0.7 Ma) are exposed. The tephra falls are related to explosive activity and show a decreasing thickness from the Capo Vaticano area southeastward. The presence of lithics indicates a provenance from a source located not far from Capo Vaticano. The combined interpretation of the magnetic and available geological data reveal that (1) the Capo Vaticano WNW‐ESE elongated positive magnetic anomaly is due to the occurrence of a WNW‐ESE elongated sill; (2) such a sill represents the remnant of the plumbing system of a Pleistocene volcano that erupted explosively producing the pumice tephra exposed in Calabria; and (3) the volcanism is consistent with the Aeolian products, in terms of age, magnetic signature, and geochemical affinity of the erupted products,. The results indicate that such volcanism developed along seismically active faults transversal to the general trend of the Aeolian Arc and Calabria block, in an area where uplift is maximized (∼4 mm/yr). Such uplift could also be responsible for fragmentation of the upper crust and formation of transversal faults along which seismic activity and volcanism occur.

    Seamless Estimation of Hydrometeorological Risk Across Spatial Scales (2021)
    Details
    Publication Date: 2021-07-24
    Description: Hydrometeorological hazards caused losses of approximately 110 billion U.S. Dollars in 2016 worldwide. Current damage estimations do not consider the uncertainties in a comprehensive way, and they are not consistent between spatial scales. Aggregated land use data are used at larger spatial scales, although detailed exposure data at the object level, such as openstreetmap.org, is becoming increasingly available across the globe. We present a probabilistic approach for object-based damage estimation which represents uncertainties and is fully scalable in space. The approach is applied and validated to company damage from the flood of 2013 in Germany. Damage estimates are more accurate compared to damage models using land use data, and the estimation works reliably at all spatial scales. Therefore, it can as well be used for pre-event analysis and risk assessments. This method takes hydrometeorological damage estimation and risk assessments to the next level, making damage estimates and their uncertainties fully scalable in space, from object to country level, and enabling the exploitation of new exposure data.

    Final Evaluation Memorandum: Strategies for Resolving Low Dissolved Oxygen and Methylmercury Events in Northern Suisun Marsh (2021)

    Description: The purpose of the project is to improve our understanding about best management practices that can be utilized on diked managed wetlands in Suisun Marsh for reducing the occurrence of low dissolved oxygen (DO) and high methylmercury (MeHg) events associated primarily with fall flood-up practices. Low DO events are of concern because they can lead to undue stress and even mortality of sensitive aquatic organisms. Elevated MeHg levels are of concern because MeHg is a neurotoxin that bio-magnifies up the food chain and can cause deleterious effects to higher trophic level consumers such as piscivorous fish, birds, and mammals (including humans). This study involved two years (2007-2008) of intensive field data collection at two managed wetland sites in northwest Suisun Marsh and their surrounding tidal sloughs, an area with prior documented low DO events. In addition, the study collected limited soils and water quality field data and mapped vegetation for three managed wetland sites in the central interior of Suisun Marsh, for the purpose of examining whether wetlands at other locations exhibit characteristics that could indicate potential for similar concerns. In Year 1 of the study, the objective was to identify the baseline conditions in the managed wetlands and determine which physical management conditions could be modified for Year 2 to reduce low DO and MeHg production issues most effectively. The objective of Year 2 was to evaluate the effectiveness of these modified management actions at reducing production of low DO and elevated MeHg conditions within the managed wetlands and to continue improving understanding of the underlying biogeochemical processes at play. This Final Evaluation Memorandum examined a total of 19 BMPs, 14 involving modified water management operations and the remaining five involving modified soil and vegetation management practices. Some of these BMPs were previously employed and others have not yet been tested. For each BMP this report assesses its efficacy in improving water quality conditions and potential conflicts with wetland management. It makes recommendations for further study (either feasibility assessments or field testing) and whether to consider for future use. Certain previously used BMPs were found to be important contributors to poor water quality conditions and their continued use is not recommended. Some BMPs that could improve water quality conditions appear difficult to implement in regards to compatibility with wetland management; these BMPs require further elaboration and feasibility assessment to determine whether they should be field tested. In practice for any given wetland, there is likely a combination of BMPs that would together have the greatest potential to address the low DO and high MeHg water quality concerns. Consequently, this report makes no sweeping recommendations applicable to large groups of wetlands but instead promotes a careful consideration of factors at each wetland or small groups of wetlands and from that assessment to apply the most effective suite of BMPs.This report also identifies a number of recommended future actions and studies. These recommendations are geared toward improving the process understanding of factors that promote low DO and high MeHg conditions, the extent of these problems in Suisun Marsh, the regulatory basis for the DO standards for a large estuarine marsh, the economics of BMPs, and alternative approaches to BMPs on diked managed wetlands that may address the water quality issues. The most important of these recommendations is that future BMP implementation should be carried out within the context of rigorous scientific evaluation so as to gain the maximum improvement in how to manage these water quality issues in the diked managed wetlands of Suisun Marsh.

    Description: Phenyl-mercuric lactate is included in the pulp processing reagents by some paper mills to eliminate slime formation in the pulp. Small quantities of this chemical are added to the wet pulp in the beaters, particularly for the bactericidal action against Aerobacter aerogenes. Subsequently the mecurial is carried away in the wash waters. However, as the highly poisonous nature of many compounds of mercury is well known, questions have been raised concerning the pollution hazards created by phenyl-mercuric lactate in streams receiving effluents from mills using this substance.

    Description: This study is an attempt to evaluate the biomonitoring capabilities of rock oyster, Saccostrea cucullata, for mercury (Hg) pollution. The oyster and sediment samples were collected from 10 rocky habitats of Qeshm and Hormoz Islands in the Persian Gulf. The concentration of mercury in the shell and soft tissues of the oysters and sediments were analyzed using an advanced mercury analyzer. Biota-sediment accumulation factor (BSAF) was calculated based on the ratio of Hg concentrations in soft tissues to that in sediments.The results showed that the rate of mercury accumulation in the soft tissues of the oyster was significantly higher than that in its shell (P 〈 0.05). There was a significant correlation between mercury concentrations in the soft tissues and the sediments (r =0.75). According to BSAF, soft tissues of the oyster were recognized as an appropriate indicator for biomonitoring mercury. The present study generally supports the usability of soft tissue of S. cucullata as a sensitive biomonitoring organ to warn mercury pollution in the Persian Gulf.

    Description: Previous studies showed that the level of mercury in Sanandaj Gheshlagh Reservoir (SGR) was higher than limits established by the World Health Organization. Total Mercury (T-Hg) concentrations in white muscle, red muscle and liver tissues of Common carp as the most consumed fish in the region were investigated. For the first time the content of mercury in red muscle tissue was measured and compared with white muscle and liver tissues. During the July to December 2009, 24 Common carp were caught from SGR (4 samples per month). THg concentrations in above mentioned tissues were measured, using Mercury Analyzer. T-Hg concentrations variations in white muscle, red muscle and liver tissues were (123-458), (115- 455) and (107-303) ng g-1, respectively. Statically significant differences were found between three tissues. A significant monthly variations of T-Hg concentrations were observed within liver tissue samples. Fish weights in this ranged between 330.1 to 753 grams. T-Hg in white and red muscle tissues in all samples weighted above 500 grams were higher than the limits established by the EPA. Therefore, additional researches are needed to evaluate any potential effluence of this fish consumption on people health.

    Description: Because mercury, a toxic metallic element, has been shown to bioaccumulate in fish tissue, humans consuming fish can potentially consume significant levels of mercury. Limited information is available on mercury levels in Florida’s marine and estuarine fish species. We examined the concentration of mercury in 2,832 fish representing 81 species from 32 families. Species represented all major trophic groups, from primary consumers to apex predators. Mercury concentrations in individual fish varied greatly within and among species. However, the majority of individuals we examined contained low concentrations. Species with very low mean or median mercury concentrations tended to be planktivores, detritivores, species that feed on invertebrates, or species that feed on benthic invertebrates and small fish. Apex predators typically had the highest mercury concentrations. In most species, mercury concentration increased as fish size increased. Sampling in Florida waters is continuing, and future research relating mercury levels to fish age, feeding ecology, and the trophic structure of Florida’s marine and estuarine ecosystems will help us to further identify important sources of variation.

    Description: In this study the amounts of mercury (Hg) were determined in tentacles and muscle tissues of O. ehrenbergii and S. buccalis from two coastal sites of Karachi; Buleji and Sunehri during Southwest monsoon (August and September) and Northeast monsoon (December and January) seasons of the year 2018. The mean amounts of Hg in edible tissues of sea cucumbers were as follows: O. ehrenbergii (0.0176 mg/kg dry wt.) and S. buccalis (0.0155 mg/kg dry wt.). Hg amounts in muscles of both species are much lower than the maximum permissible limits (0.5 mg/kg wet wt.). Estimated Daily Intakes for adults consuming O. ehrenbergii and S. buccalis are lower than published RfD values. Total Target Hazard Quotient (TTHQ) values (0.00787) are also lower than 1, it may be concluded that the consumption of these sea cucumbers from Karachi, do not pose any health hazards to human as Hg amounts were concerned.

    Description: The Florida Fish and Wildlife Conservation Commission’s Florida Marine Research Institute (FWC-FMRI) hasexamined total mercury levels in muscle tissue from a variety of economically and ecologically important speciesas part of an ongoing study to better understand mercury contamination in marine fishes.The FWC-FMRI MercuryProgram is one of the most comprehensive programs in the United States for monitoring mercury levels inmarine and estuarine fishes. Because mercury, a toxic metallic element, has been shown to bioaccumulate in fishtissue, humans consuming fish can potentially consume significant levels of mercury.We examined the concentrationof total mercury in 6,806 fish, representing 108 species from 40 families. Species represented all major trophicgroups, from primary consumers to apex predators.The majority of individuals we examined contained low concentrationsof mercury, but concentrations in individual fish varied greatly within and among species. Specieswith very low mean or median mercury concentrations tended to be planktivores, detritivores, species that feedon invertebrates, or species that feed on invertebrates and small fish prey.Apex predators typically had the highestmercury concentrations. In most species, mercury concentration increased as fish size increased. Samplingin Florida waters is continuing, and future research relating mercury levels to fish age, feeding ecology, and thetrophic structure of Florida’s marine and estuarine ecosystems will help us better understand concentrations ofthis element in marine fishes.

    Description: For assessing the status of the marine environment of the North Sea and the Baltic Sea, international monitoring programmes are performed in the framework of the international conventions for the protection of the marine environment of the North Atlantic Ocean and the Baltic Sea. The German contribution to these programmes is covered by the national Joint Marine Monitoring Programme, which is carried out by several institutes of the coastal Federal States and the Federal Government of Germany. The Institute for Fishery Ecology of the Federal Fisheries Research Centreis responsible for the investigations of harmful substancesin fish samples from the open sea areas. This article gives a short description of how this task is performed and, as an example, how concentrations of polychlorinated biphenyls and mercury in plaice from the German Bight have developed over a period of thirteen and eight years, respectively.

    Effect of mercury contamination on the hepatopancreas ultrastructure of Armadillo officinalis duméril, 1816 (crustacea, isopoda) (2021)
    Details
    Publication Date: 2021-10-27
    Description: This study aimed to evaluate the effect of substrate contamination by mercury on the hepatopancreas of the Crustacean species; Armadillo officinalis Duméril, 1816. Uncontaminated specimens were collected from the banks of Ghar El Melh lagoon then exposed for three weeks to three concentrations of mercury salt solution. After the end of the exposure, the hepatopancreas of unexposed and exposed animals were compared to detect histological changes. Transmission Electron Microscopy observations showed that the hepatopancreas of Hg-exposed animals showed morphological and histological changes compared with control animals even at the lowest concentration. The degree of these alterations was found to be dose-dependent. The global predominant features were: microvillus border disruption, condensation of some cytoplasm areas and of chromatin, rough endoplasmic reticulum and mitochondrial alterations, lipid droplets modifications in addition to the increasing number of B-granules in the B and S cells.
    Description: Cette étude vise à évaluer l’effet de la contamination du substrat par le mercure sur l’hépatopancréas de l’espèce de Crustacés; Armadillo officinalis Duméril, 1816. Des échantillons non contaminés ont été recueillis sur les rives de la lagune de Ghar El Melh, puis exposés pendant trois semaines à trois concentrations de solution de sel de mercure. A la fin de l'exposition, l’hépatopancréas des animaux non exposés et exposés ont été comparés pour détecter les modifications histologiques. Les observations en microscopie électronique à transmission ont montré que l'hépatopancréas des animaux exposés au mercure présentait des changements morphologiques et histologiques par rapport aux animaux témoins, même à la concentration la plus faible. Le degré de ces altérations s'est avéré dépendant de la dose. Les principales caractéristiques globales étaient: la rupture de la frontière des microvillosités, la condensation de certaines zones du cytoplasme et de la chromatine, l’altération du réticulum endoplasmique rugueux et des mitochondries, la modification des gouttelettes lipidiques en plus du nombre croissant de granules B dans les cellules B et S.

    Description: The behaviour of metals in aquatic ecosystems is dependent on various environmental factors. Experiments were conducted in five different contact times (0.5, 2, 12, 24 and 48h) between soil sediment and mercury on Cyprinus carpio var communis. It was observed that contact time with soil sediment had significant effect in reducing the toxicity of mercury. Higher the time of contact, greater the effect. Medium hard water (150 mg/L CaC0 sub(3) of total hardness) had the highest effect as compared to other water in reducing the toxicity of mercury when combined with underlying soil sediment. With the increase in contact time, complexation and adsorption of inorganic mercury ions with the dissolved and particulate phases of water and soil sediment were increased; thereby bioaccumulation of mercury ions by scale carp was more. Applicability of the result of this experiment in natural ecosystems was also suggested.

    Description: The acute toxicity test conducted by static bioassay techniques have revealed that among selected heavy metals, copper is more toxic than zinc and mercury to Planaxis sulcatus and Trochus radiatus. The natural availability of heavy metals in the surrounding environment of these organisms is found to be deciding factor for their toxicity. Natural habitat of the animal also contributes to the sensitivity of a particular animal to the heavy metals tested. In addition the tendency of the animal to overcome the adverse conditions in their surrounding also plays a significant role in toxicity of pollutants.

    Description: Lethal and sub-lethal effects of mercury have been studied in Perna viridis and Modiolus carvalhoi. For P. viridis LC30 is 1.0 p.p.m. at 48 h and 0.23 p.p.m. at 96 h. Recorded LC50 values for M. carvalhoi are 0.5 p.p.m. and 0.19 p.p.m. at 48 h and 96 h respectively. The results document that these two species, although inhabiting the same area in the tidal belt, exhibit clear differences in mercury resistance. It is further shown that the duration of exposure affects mortality rates. In sub-lethal concentration, between 0.01 and 0.10 p.p.m. decrease in pedal-gland activity is conspicuous in P. viridis. At concentrations much below LC50 values (at 96 h), although some animals are alive, pedal-gland activity is totally suspended, supporting the assumption that shell closure ability plays a minor role in byssus thread production. In M. carvalhoi total cessation of pedal gland activity occurred at 0.09 p.p.m. of mercury.

    Description: Chitosan from prawn waste was used for the removal of mercury from solutions. Mercuric chloride solutions containing 250, 500, 1000, 10000 and 100000 ng of Hg super(+2)/ml were treated with chitosan samples of different particle size for different periods. The effect of initial concentration of mercury in the solution, particle size of chitosan and time of treatment on the adsorption of Hg super(+2) was studied. The residual mercury content after treatment for ten min. with chitosan of 40 mesh size from a solution of initial concentration 10000 ng/ml was 10 ng/ml whereas it was 50 ng/ml for chitosan of larger particle size (10-20 mesh). From solutions of lower concentrations complete removal of mercury was possible by chitosan treatment. Though the particle size and time of treatment have significant effect, the concentration of mercury in solution is more influential on the removal of mercury from solution.

    The genome-wide structure of the Jewish people (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-06-10
    Description: Contemporary Jews comprise an aggregate of ethno-religious communities whose worldwide members identify with each other through various shared religious, historical and cultural traditions. Historical evidence suggests common origins in the Middle East, followed by migrations leading to the establishment of communities of Jews in Europe, Africa and Asia, in what is termed the Jewish Diaspora. This complex demographic history imposes special challenges in attempting to address the genetic structure of the Jewish people. Although many genetic studies have shed light on Jewish origins and on diseases prevalent among Jewish communities, including studies focusing on uniparentally and biparentally inherited markers, genome-wide patterns of variation across the vast geographic span of Jewish Diaspora communities and their respective neighbours have yet to be addressed. Here we use high-density bead arrays to genotype individuals from 14 Jewish Diaspora communities and compare these patterns of genome-wide diversity with those from 69 Old World non-Jewish populations, of which 25 have not previously been reported. These samples were carefully chosen to provide comprehensive comparisons between Jewish and non-Jewish populations in the Diaspora, as well as with non-Jewish populations from the Middle East and north Africa. Principal component and structure-like analyses identify previously unrecognized genetic substructure within the Middle East. Most Jewish samples form a remarkably tight subcluster that overlies Druze and Cypriot samples but not samples from other Levantine populations or paired Diaspora host populations. In contrast, Ethiopian Jews (Beta Israel) and Indian Jews (Bene Israel and Cochini) cluster with neighbouring autochthonous populations in Ethiopia and western India, respectively, despite a clear paternal link between the Bene Israel and the Levant. These results cast light on the variegated genetic architecture of the Middle East, and trace the origins of most Jewish Diaspora communities to the Levant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Behar, Doron M -- Yunusbayev, Bayazit -- Metspalu, Mait -- Metspalu, Ene -- Rosset, Saharon -- Parik, Juri -- Rootsi, Siiri -- Chaubey, Gyaneshwer -- Kutuev, Ildus -- Yudkovsky, Guennady -- Khusnutdinova, Elza K -- Balanovsky, Oleg -- Semino, Ornella -- Pereira, Luisa -- Comas, David -- Gurwitz, David -- Bonne-Tamir, Batsheva -- Parfitt, Tudor -- Hammer, Michael F -- Skorecki, Karl -- Villems, Richard -- England -- Nature. 2010 Jul 8;466(7303):238-42. doi: 10.1038/nature09103.

    The structural basis for autonomous dimerization of the pre-T-cell antigen receptor (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-10-15
    Description: The pre-T-cell antigen receptor (pre-TCR), expressed by immature thymocytes, has a pivotal role in early T-cell development, including TCR beta-selection, survival and proliferation of CD4(-)CD8(-) double-negative thymocytes, and subsequent alphabeta T-cell lineage differentiation. Whereas alphabetaTCR ligation by the peptide-loaded major histocompatibility complex initiates T-cell signalling, pre-TCR-induced signalling occurs by means of a ligand-independent dimerization event. The pre-TCR comprises an invariant alpha-chain (pre-Talpha) that pairs with any TCR beta-chain (TCRbeta) following successful TCR beta-gene rearrangement. Here we provide the basis of pre-Talpha-TCRbeta assembly and pre-TCR dimerization. The pre-Talpha chain comprised a single immunoglobulin-like domain that is structurally distinct from the constant (C) domain of the TCR alpha-chain; nevertheless, the mode of association between pre-Talpha and TCRbeta mirrored that mediated by the Calpha-Cbeta domains of the alphabetaTCR. The pre-TCR had a propensity to dimerize in solution, and the molecular envelope of the pre-TCR dimer correlated well with the observed head-to-tail pre-TCR dimer. This mode of pre-TCR dimerization enabled the pre-Talpha domain to interact with the variable (V) beta domain through residues that are highly conserved across the Vbeta and joining (J) beta gene families, thus mimicking the interactions at the core of the alphabetaTCR's Valpha-Vbeta interface. Disruption of this pre-Talpha-Vbeta dimer interface abrogated pre-TCR dimerization in solution and impaired pre-TCR expression on the cell surface. Accordingly, we provide a mechanism of pre-TCR self-association that allows the pre-Talpha chain to simultaneously 'sample' the correct folding of both the V and C domains of any TCR beta-chain, regardless of its ultimate specificity, which represents a critical checkpoint in T-cell development. This unusual dual-chaperone-like sensing function of pre-Talpha represents a unique mechanism in nature whereby developmental quality control regulates the expression and signalling of an integral membrane receptor complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pang, Siew Siew -- Berry, Richard -- Chen, Zhenjun -- Kjer-Nielsen, Lars -- Perugini, Matthew A -- King, Glenn F -- Wang, Christina -- Chew, Sock Hui -- La Gruta, Nicole L -- Williams, Neal K -- Beddoe, Travis -- Tiganis, Tony -- Cowieson, Nathan P -- Godfrey, Dale I -- Purcell, Anthony W -- Wilce, Matthew C J -- McCluskey, James -- Rossjohn, Jamie -- England -- Nature. 2010 Oct 14;467(7317):844-8. doi: 10.1038/nature09448.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Protein Crystallography Unit, Department of Biochemistry and Molecular Biology, School of Biomedical Sciences, Monash University, Clayton, Victoria 3800, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20944746" target="_blank"〉PubMed〈/a〉

    Foot strike patterns and collision forces in habitually barefoot versus shod runners (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-01-30
    Description: Humans have engaged in endurance running for millions of years, but the modern running shoe was not invented until the 1970s. For most of human evolutionary history, runners were either barefoot or wore minimal footwear such as sandals or moccasins with smaller heels and little cushioning relative to modern running shoes. We wondered how runners coped with the impact caused by the foot colliding with the ground before the invention of the modern shoe. Here we show that habitually barefoot endurance runners often land on the fore-foot (fore-foot strike) before bringing down the heel, but they sometimes land with a flat foot (mid-foot strike) or, less often, on the heel (rear-foot strike). In contrast, habitually shod runners mostly rear-foot strike, facilitated by the elevated and cushioned heel of the modern running shoe. Kinematic and kinetic analyses show that even on hard surfaces, barefoot runners who fore-foot strike generate smaller collision forces than shod rear-foot strikers. This difference results primarily from a more plantarflexed foot at landing and more ankle compliance during impact, decreasing the effective mass of the body that collides with the ground. Fore-foot- and mid-foot-strike gaits were probably more common when humans ran barefoot or in minimal shoes, and may protect the feet and lower limbs from some of the impact-related injuries now experienced by a high percentage of runners.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lieberman, Daniel E -- Venkadesan, Madhusudhan -- Werbel, William A -- Daoud, Adam I -- D'Andrea, Susan -- Davis, Irene S -- Mang'eni, Robert Ojiambo -- Pitsiladis, Yannis -- England -- Nature. 2010 Jan 28;463(7280):531-5. doi: 10.1038/nature08723.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Evolutionary Biology, 11 Divinity Avenue, Harvard University, Cambridge, Massachusetts 02138, USA. danlieb@fas.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20111000" target="_blank"〉PubMed〈/a〉

    Active site remodelling accompanies thioester bond formation in the SUMO E1 (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-02-19
    Description: E1 enzymes activate ubiquitin (Ub) and ubiquitin-like (Ubl) proteins in two steps by carboxy-terminal adenylation and thioester bond formation to a conserved catalytic cysteine in the E1 Cys domain. The structural basis for these intermediates remains unknown. Here we report crystal structures for human SUMO E1 in complex with SUMO adenylate and tetrahedral intermediate analogues at 2.45 and 2.6 A, respectively. These structures show that side chain contacts to ATP.Mg are released after adenylation to facilitate a 130 degree rotation of the Cys domain during thioester bond formation that is accompanied by remodelling of key structural elements including the helix that contains the E1 catalytic cysteine, the crossover and re-entry loops, and refolding of two helices that are required for adenylation. These changes displace side chains required for adenylation with side chains required for thioester bond formation. Mutational and biochemical analyses indicate these mechanisms are conserved in other E1s.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2866016/" 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/PMC2866016/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olsen, Shaun K -- Capili, Allan D -- Lu, Xuequan -- Tan, Derek S -- Lima, Christopher D -- F32 GM075695/GM/NIGMS NIH HHS/ -- F32 GM075695-03/GM/NIGMS NIH HHS/ -- R01 AI068038/AI/NIAID NIH HHS/ -- R01 AI068038-02/AI/NIAID NIH HHS/ -- R01 AI068038-03/AI/NIAID NIH HHS/ -- R01 GM065872/GM/NIGMS NIH HHS/ -- R01 GM065872-09/GM/NIGMS NIH HHS/ -- RR-15301/RR/NCRR NIH HHS/ -- England -- Nature. 2010 Feb 18;463(7283):906-12. doi: 10.1038/nature08765.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural Biology, Sloan-Kettering Institute, New York, New York 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20164921" target="_blank"〉PubMed〈/a〉

    Helical assembly in the MyD88-IRAK4-IRAK2 complex in TLR/IL-1R signalling (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-05-21
    Description: MyD88, IRAK4 and IRAK2 are critical signalling mediators of the TLR/IL1-R superfamily. Here we report the crystal structure of the MyD88-IRAK4-IRAK2 death domain (DD) complex, which surprisingly reveals a left-handed helical oligomer that consists of 6 MyD88, 4 IRAK4 and 4 IRAK2 DDs. Assembly of this helical signalling tower is hierarchical, in which MyD88 recruits IRAK4 and the MyD88-IRAK4 complex recruits the IRAK4 substrates IRAK2 or the related IRAK1. Formation of these Myddosome complexes brings the kinase domains of IRAKs into proximity for phosphorylation and activation. Composite binding sites are required for recruitment of the individual DDs in the complex, which are confirmed by mutagenesis and previously identified signalling mutations. Specificities in Myddosome formation are dictated by both molecular complementarity and correspondence of surface electrostatics. The MyD88-IRAK4-IRAK2 complex provides a template for Toll signalling in Drosophila and an elegant mechanism for versatile assembly and regulation of DD complexes in signal transduction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2888693/" 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/PMC2888693/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Su-Chang -- Lo, Yu-Chih -- Wu, Hao -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 AI050872/AI/NIAID NIH HHS/ -- R01 AI050872-09/AI/NIAID NIH HHS/ -- England -- Nature. 2010 Jun 17;465(7300):885-90. doi: 10.1038/nature09121.

    Histone H2A deubiquitinase activity of the Polycomb repressive complex PR-DUB (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-05-04
    Description: Polycomb group (PcG) proteins are transcriptional repressors that control processes ranging from the maintenance of cell fate decisions and stem cell pluripotency in animals to the control of flowering time in plants. In Drosophila, genetic studies identified more than 15 different PcG proteins that are required to repress homeotic (HOX) and other developmental regulator genes in cells where they must stay inactive. Biochemical analyses established that these PcG proteins exist in distinct multiprotein complexes that bind to and modify chromatin of target genes. Among those, Polycomb repressive complex 1 (PRC1) and the related dRing-associated factors (dRAF) complex contain an E3 ligase activity for monoubiquitination of histone H2A (refs 1-4). Here we show that the uncharacterized Drosophila PcG gene calypso encodes the ubiquitin carboxy-terminal hydrolase BAP1. Biochemically purified Calypso exists in a complex with the PcG protein ASX, and this complex, named Polycomb repressive deubiquitinase (PR-DUB), is bound at PcG target genes in Drosophila. Reconstituted recombinant Drosophila and human PR-DUB complexes remove monoubiquitin from H2A but not from H2B in nucleosomes. Drosophila mutants lacking PR-DUB show a strong increase in the levels of monoubiquitinated H2A. A mutation that disrupts the catalytic activity of Calypso, or absence of the ASX subunit abolishes H2A deubiquitination in vitro and HOX gene repression in vivo. Polycomb gene silencing may thus entail a dynamic balance between H2A ubiquitination by PRC1 and dRAF, and H2A deubiquitination by PR-DUB.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3182123/" 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/PMC3182123/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scheuermann, Johanna C -- de Ayala Alonso, Andres Gaytan -- Oktaba, Katarzyna -- Ly-Hartig, Nga -- McGinty, Robert K -- Fraterman, Sven -- Wilm, Matthias -- Muir, Tom W -- Muller, Jurg -- R01 GM086868/GM/NIGMS NIH HHS/ -- R01 GM086868-13/GM/NIGMS NIH HHS/ -- RC2 CA148354/CA/NCI NIH HHS/ -- RC2 CA148354-02/CA/NCI NIH HHS/ -- RC2CA148354/CA/NCI NIH HHS/ -- England -- Nature. 2010 May 13;465(7295):243-7. doi: 10.1038/nature08966.

    Regulation of myeloid leukaemia by the cell-fate determinant Musashi (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-07-20
    Description: Chronic myelogenous leukaemia (CML) can progress from a slow growing chronic phase to an aggressive blast crisis phase, but the molecular basis of this transition remains poorly understood. Here we have used mouse models of CML to show that disease progression is regulated by the Musashi-Numb signalling axis. Specifically, we find that the chronic phase is marked by high levels of Numb expression whereas the blast crisis phase has low levels of Numb expression, and that ectopic expression of Numb promotes differentiation and impairs advanced-phase disease in vivo. As a possible explanation for the decreased levels of Numb in the blast crisis phase, we show that NUP98-HOXA9, an oncogene associated with blast crisis CML, can trigger expression of the RNA-binding protein Musashi2 (Msi2), which in turn represses Numb. Notably, loss of Msi2 restores Numb expression and significantly impairs the development and propagation of blast crisis CML in vitro and in vivo. Finally we show that Msi2 expression is not only highly upregulated during human CML progression but is also an early indicator of poorer prognosis. These data show that the Musashi-Numb pathway can control the differentiation of CML cells, and raise the possibility that targeting this pathway may provide a new strategy for the therapy of aggressive leukaemias.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2918284/" 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/PMC2918284/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ito, Takahiro -- Kwon, Hyog Young -- Zimdahl, Bryan -- Congdon, Kendra L -- Blum, Jordan -- Lento, William E -- Zhao, Chen -- Lagoo, Anand -- Gerrard, Gareth -- Foroni, Letizia -- Goldman, John -- Goh, Harriet -- Kim, Soo-Hyun -- Kim, Dong-Wook -- Chuah, Charles -- Oehler, Vivian G -- Radich, Jerald P -- Jordan, Craig T -- Reya, Tannishtha -- AI067798/AI/NIAID NIH HHS/ -- CA122206/CA/NCI NIH HHS/ -- CA140371/CA/NCI NIH HHS/ -- CA18029/CA/NCI NIH HHS/ -- DK072234/DK/NIDDK NIH HHS/ -- DK63031/DK/NIDDK NIH HHS/ -- DP1 CA174422/CA/NCI NIH HHS/ -- DP1 OD006430/OD/NIH HHS/ -- DP1 OD006430-01/OD/NIH HHS/ -- DP1 OD006430-02/OD/NIH HHS/ -- DP1OD006430/OD/NIH HHS/ -- HL097767/HL/NHLBI NIH HHS/ -- P01 CA018029/CA/NCI NIH HHS/ -- R01 CA140371/CA/NCI NIH HHS/ -- R01 DK063031/DK/NIDDK NIH HHS/ -- R01 DK063031-01/DK/NIDDK NIH HHS/ -- R01 DK063031-01S1/DK/NIDDK NIH HHS/ -- R01 DK063031-02/DK/NIDDK NIH HHS/ -- R01 DK063031-03/DK/NIDDK NIH HHS/ -- R01 DK063031-04/DK/NIDDK NIH HHS/ -- R01 DK063031-05/DK/NIDDK NIH HHS/ -- R01 DK063031-06/DK/NIDDK NIH HHS/ -- R01 DK063031-07/DK/NIDDK NIH HHS/ -- R01 DK063031-07S1/DK/NIDDK NIH HHS/ -- R01 DK063031-08/DK/NIDDK NIH HHS/ -- R01 DK072234/DK/NIDDK NIH HHS/ -- R01 DK072234-01A1/DK/NIDDK NIH HHS/ -- R01 DK072234-02/DK/NIDDK NIH HHS/ -- R01 DK072234-03/DK/NIDDK NIH HHS/ -- R01 DK072234-04/DK/NIDDK NIH HHS/ -- R01 HL097767/HL/NHLBI NIH HHS/ -- R01 HL097767-01/HL/NHLBI NIH HHS/ -- R01 HL097767-02/HL/NHLBI NIH HHS/ -- T32 GM007184-33/GM/NIGMS NIH HHS/ -- U19 AI067798/AI/NIAID NIH HHS/ -- U19 AI067798-010006/AI/NIAID NIH HHS/ -- U19 AI067798-020006/AI/NIAID NIH HHS/ -- U19 AI067798-030006/AI/NIAID NIH HHS/ -- U19 AI067798-040006/AI/NIAID NIH HHS/ -- U19 AI067798-050006/AI/NIAID NIH HHS/ -- England -- Nature. 2010 Aug 5;466(7307):765-8. doi: 10.1038/nature09171.

    Thousands of chemical starting points for antimalarial lead identification (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-05-21
    Description: Malaria is a devastating infection caused by protozoa of the genus Plasmodium. Drug resistance is widespread, no new chemical class of antimalarials has been introduced into clinical practice since 1996 and there is a recent rise of parasite strains with reduced sensitivity to the newest drugs. We screened nearly 2 million compounds in GlaxoSmithKline's chemical library for inhibitors of P. falciparum, of which 13,533 were confirmed to inhibit parasite growth by at least 80% at 2 microM concentration. More than 8,000 also showed potent activity against the multidrug resistant strain Dd2. Most (82%) compounds originate from internal company projects and are new to the malaria community. Analyses using historic assay data suggest several novel mechanisms of antimalarial action, such as inhibition of protein kinases and host-pathogen interaction related targets. Chemical structures and associated data are hereby made public to encourage additional drug lead identification efforts and further research into this disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gamo, Francisco-Javier -- Sanz, Laura M -- Vidal, Jaume -- de Cozar, Cristina -- Alvarez, Emilio -- Lavandera, Jose-Luis -- Vanderwall, Dana E -- Green, Darren V S -- Kumar, Vinod -- Hasan, Samiul -- Brown, James R -- Peishoff, Catherine E -- Cardon, Lon R -- Garcia-Bustos, Jose F -- England -- Nature. 2010 May 20;465(7296):305-10. doi: 10.1038/nature09107.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tres Cantos Medicines Development Campus, GlaxoSmithKline, Severo Ochoa 2, 28760 Tres Cantos, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20485427" target="_blank"〉PubMed〈/a〉

    A coding-independent function of gene and pseudogene mRNAs regulates tumour biology (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-06-26
    Description: The canonical role of messenger RNA (mRNA) is to deliver protein-coding information to sites of protein synthesis. However, given that microRNAs bind to RNAs, we hypothesized that RNAs could possess a regulatory role that relies on their ability to compete for microRNA binding, independently of their protein-coding function. As a model for the protein-coding-independent role of RNAs, we describe the functional relationship between the mRNAs produced by the PTEN tumour suppressor gene and its pseudogene PTENP1 and the critical consequences of this interaction. We find that PTENP1 is biologically active as it can regulate cellular levels of PTEN and exert a growth-suppressive role. We also show that the PTENP1 locus is selectively lost in human cancer. We extended our analysis to other cancer-related genes that possess pseudogenes, such as oncogenic KRAS. We also demonstrate that the transcripts of protein-coding genes such as PTEN are biologically active. These findings attribute a novel biological role to expressed pseudogenes, as they can regulate coding gene expression, and reveal a non-coding function for mRNAs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3206313/" 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/PMC3206313/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Poliseno, Laura -- Salmena, Leonardo -- Zhang, Jiangwen -- Carver, Brett -- Haveman, William J -- Pandolfi, Pier Paolo -- R01 CA-82328-09/CA/NCI NIH HHS/ -- R01 CA102142/CA/NCI NIH HHS/ -- R01 CA102142-07/CA/NCI NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2010 Jun 24;465(7301):1033-8. doi: 10.1038/nature09144.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Genetics Program, Beth Israel Deaconess Cancer Center, Department of Medicine, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts 02215, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20577206" target="_blank"〉PubMed〈/a〉

    Genome-wide RNAi screen identifies human host factors crucial for influenza virus replication (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-01-19
    Description: Influenza A virus, being responsible for seasonal epidemics and reoccurring pandemics, represents a worldwide threat to public health. High mutation rates facilitate the generation of viral escape mutants, rendering vaccines and drugs directed against virus-encoded targets potentially ineffective. In contrast, targeting host cell determinants temporarily dispensable for the host but crucial for virus replication could prevent viral escape. Here we report the discovery of 287 human host cell genes influencing influenza A virus replication in a genome-wide RNA interference (RNAi) screen. Using an independent assay we confirmed 168 hits (59%) inhibiting either the endemic H1N1 (119 hits) or the current pandemic swine-origin (121 hits) influenza A virus strains, with an overlap of 60%. Notably, a subset of these common hits was also essential for replication of a highly pathogenic avian H5N1 strain. In-depth analyses of several factors provided insights into their infection stage relevance. Notably, SON DNA binding protein (SON) was found to be important for normal trafficking of influenza virions to late endosomes early in infection. We also show that a small molecule inhibitor of CDC-like kinase 1 (CLK1) reduces influenza virus replication by more than two orders of magnitude, an effect connected with impaired splicing of the viral M2 messenger RNA. Furthermore, influenza-virus-infected p27(-/-) (cyclin-dependent kinase inhibitor 1B; Cdkn1b) mice accumulated significantly lower viral titres in the lung, providing in vivo evidence for the importance of this gene. Thus, our results highlight the potency of genome-wide RNAi screening for the dissection of virus-host interactions and the identification of drug targets for a broad range of influenza viruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karlas, Alexander -- Machuy, Nikolaus -- Shin, Yujin -- Pleissner, Klaus-Peter -- Artarini, Anita -- Heuer, Dagmar -- Becker, Daniel -- Khalil, Hany -- Ogilvie, Lesley A -- Hess, Simone -- Maurer, Andre P -- Muller, Elke -- Wolff, Thorsten -- Rudel, Thomas -- Meyer, Thomas F -- England -- Nature. 2010 Feb 11;463(7282):818-22. doi: 10.1038/nature08760.

    Origin of the human malaria parasite Plasmodium falciparum in gorillas (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-09-25
    Description: Plasmodium falciparum is the most prevalent and lethal of the malaria parasites infecting humans, yet the origin and evolutionary history of this important pathogen remain controversial. Here we develop a single-genome amplification strategy to identify and characterize Plasmodium spp. DNA sequences in faecal samples from wild-living apes. Among nearly 3,000 specimens collected from field sites throughout central Africa, we found Plasmodium infection in chimpanzees (Pan troglodytes) and western gorillas (Gorilla gorilla), but not in eastern gorillas (Gorilla beringei) or bonobos (Pan paniscus). Ape plasmodial infections were highly prevalent, widely distributed and almost always made up of mixed parasite species. Analysis of more than 1,100 mitochondrial, apicoplast and nuclear gene sequences from chimpanzees and gorillas revealed that 99% grouped within one of six host-specific lineages representing distinct Plasmodium species within the subgenus Laverania. One of these from western gorillas comprised parasites that were nearly identical to P. falciparum. In phylogenetic analyses of full-length mitochondrial sequences, human P. falciparum formed a monophyletic lineage within the gorilla parasite radiation. These findings indicate that P. falciparum is of gorilla origin and not of chimpanzee, bonobo or ancient human origin.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997044/" 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/PMC2997044/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Weimin -- Li, Yingying -- Learn, Gerald H -- Rudicell, Rebecca S -- Robertson, Joel D -- Keele, Brandon F -- Ndjango, Jean-Bosco N -- Sanz, Crickette M -- Morgan, David B -- Locatelli, Sabrina -- Gonder, Mary K -- Kranzusch, Philip J -- Walsh, Peter D -- Delaporte, Eric -- Mpoudi-Ngole, Eitel -- Georgiev, Alexander V -- Muller, Martin N -- Shaw, George M -- Peeters, Martine -- Sharp, Paul M -- Rayner, Julian C -- Hahn, Beatrice H -- P30 AI 7767/AI/NIAID NIH HHS/ -- P30 AI027767/AI/NIAID NIH HHS/ -- P30 AI027767-21A1/AI/NIAID NIH HHS/ -- R01 AI058715/AI/NIAID NIH HHS/ -- R01 AI058715-06A1/AI/NIAID NIH HHS/ -- R01 AI058715-07/AI/NIAID NIH HHS/ -- R01 AI50529/AI/NIAID NIH HHS/ -- R01 I58715/PHS HHS/ -- R03 AI074778/AI/NIAID NIH HHS/ -- R03 AI074778-02/AI/NIAID NIH HHS/ -- R37 AI050529/AI/NIAID NIH HHS/ -- R37 AI050529-07/AI/NIAID NIH HHS/ -- R37 AI050529-08/AI/NIAID NIH HHS/ -- T32 AI007245/AI/NIAID NIH HHS/ -- T32 AI007245-26/AI/NIAID NIH HHS/ -- T32 GM008111/GM/NIGMS NIH HHS/ -- T32 GM008111-13/GM/NIGMS NIH HHS/ -- U19 AI 067854/AI/NIAID NIH HHS/ -- U19 AI067854/AI/NIAID NIH HHS/ -- U19 AI067854-06/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- Wellcome Trust/United Kingdom -- England -- Nature. 2010 Sep 23;467(7314):420-5. doi: 10.1038/nature09442.〈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/20864995" target="_blank"〉PubMed〈/a〉

    Enzyme-inhibitor-like tuning of Ca(2+) channel connectivity with calmodulin (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-02-09
    Description: Ca(2+) channels and calmodulin (CaM) are two prominent signalling hubs that synergistically affect functions as diverse as cardiac excitability, synaptic plasticity and gene transcription. It is therefore fitting that these hubs are in some sense coordinated, as the opening of Ca(V)1-2 Ca(2+) channels are regulated by a single CaM constitutively complexed with channels. The Ca(2+)-free form of CaM (apoCaM) is already pre-associated with the isoleucine-glutamine (IQ) domain on the channel carboxy terminus, and subsequent Ca(2+) binding to this 'resident' CaM drives conformational changes that then trigger regulation of channel opening. Another potential avenue for channel-CaM coordination could arise from the absence of Ca(2+) regulation in channels lacking a pre-associated CaM. Natural fluctuations in CaM concentrations might then influence the fraction of regulable channels and, thereby, the overall strength of Ca(2+) feedback. However, the prevailing view has been that the ultrastrong affinity of channels for apoCaM ensures their saturation with CaM, yielding a significant form of concentration independence between Ca(2+) channels and CaM. Here we show that significant exceptions to this autonomy exist, by combining electrophysiology (to characterize channel regulation) with optical fluorescence resonance energy transfer (FRET) sensor determination of free-apoCaM concentration in live cells. This approach translates quantitative CaM biochemistry from the traditional test-tube context into the realm of functioning holochannels within intact cells. From this perspective, we find that long splice forms of Ca(V)1.3 and Ca(V)1.4 channels include a distal carboxy tail that resembles an enzyme competitive inhibitor that retunes channel affinity for apoCaM such that natural CaM variations affect the strength of Ca(2+) feedback modulation. Given the ubiquity of these channels, the connection between ambient CaM levels and Ca(2+) entry through channels is broadly significant for Ca(2+) homeostasis. Strategies such as ours promise key advances for the in situ analysis of signalling molecules resistant to in vitro reconstitution, such as Ca(2+) channels.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3553577/" 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/PMC3553577/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Xiaodong -- Yang, Philemon S -- Yang, Wanjun -- Yue, David T -- P30 DC005211/DC/NIDCD NIH HHS/ -- R01 DC000276/DC/NIDCD NIH HHS/ -- England -- Nature. 2010 Feb 18;463(7283):968-72. doi: 10.1038/nature08766.

    COT drives resistance to RAF inhibition through MAP kinase pathway reactivation (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-11-26
    Description: Oncogenic mutations in the serine/threonine kinase B-RAF (also known as BRAF) are found in 50-70% of malignant melanomas. Pre-clinical studies have demonstrated that the B-RAF(V600E) mutation predicts a dependency on the mitogen-activated protein kinase (MAPK) signalling cascade in melanoma-an observation that has been validated by the success of RAF and MEK inhibitors in clinical trials. However, clinical responses to targeted anticancer therapeutics are frequently confounded by de novo or acquired resistance. Identification of resistance mechanisms in a manner that elucidates alternative 'druggable' targets may inform effective long-term treatment strategies. Here we expressed approximately 600 kinase and kinase-related open reading frames (ORFs) in parallel to interrogate resistance to a selective RAF kinase inhibitor. We identified MAP3K8 (the gene encoding COT/Tpl2) as a MAPK pathway agonist that drives resistance to RAF inhibition in B-RAF(V600E) cell lines. COT activates ERK primarily through MEK-dependent mechanisms that do not require RAF signalling. Moreover, COT expression is associated with de novo resistance in B-RAF(V600E) cultured cell lines and acquired resistance in melanoma cells and tissue obtained from relapsing patients following treatment with MEK or RAF inhibitors. We further identify combinatorial MAPK pathway inhibition or targeting of COT kinase activity as possible therapeutic strategies for reducing MAPK pathway activation in this setting. Together, these results provide new insights into resistance mechanisms involving the MAPK pathway and articulate an integrative approach through which high-throughput functional screens may inform the development of novel therapeutic strategies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3058384/" 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/PMC3058384/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johannessen, Cory M -- Boehm, Jesse S -- Kim, So Young -- Thomas, Sapana R -- Wardwell, Leslie -- Johnson, Laura A -- Emery, Caroline M -- Stransky, Nicolas -- Cogdill, Alexandria P -- Barretina, Jordi -- Caponigro, Giordano -- Hieronymus, Haley -- Murray, Ryan R -- Salehi-Ashtiani, Kourosh -- Hill, David E -- Vidal, Marc -- Zhao, Jean J -- Yang, Xiaoping -- Alkan, Ozan -- Kim, Sungjoon -- Harris, Jennifer L -- Wilson, Christopher J -- Myer, Vic E -- Finan, Peter M -- Root, David E -- Roberts, Thomas M -- Golub, Todd -- Flaherty, Keith T -- Dummer, Reinhard -- Weber, Barbara L -- Sellers, William R -- Schlegel, Robert -- Wargo, Jennifer A -- Hahn, William C -- Garraway, Levi A -- CA134502/CA/NCI NIH HHS/ -- DP2 OD002750/OD/NIH HHS/ -- DP2 OD002750-01/OD/NIH HHS/ -- K08 CA115927/CA/NCI NIH HHS/ -- K08 CA115927-05/CA/NCI NIH HHS/ -- P50 CA093683/CA/NCI NIH HHS/ -- R01 CA134502/CA/NCI NIH HHS/ -- R33 CA128625/CA/NCI NIH HHS/ -- RC2 CA148268/CA/NCI NIH HHS/ -- England -- Nature. 2010 Dec 16;468(7326):968-72. doi: 10.1038/nature09627.

    Chemical genetics strategy identifies an HCV NS5A inhibitor with a potent clinical effect (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-04-23
    Description: The worldwide prevalence of chronic hepatitis C virus (HCV) infection is estimated to be approaching 200 million people. Current therapy relies upon a combination of pegylated interferon-alpha and ribavirin, a poorly tolerated regimen typically associated with less than 50% sustained virological response rate in those infected with genotype 1 virus. The development of direct-acting antiviral agents to treat HCV has focused predominantly on inhibitors of the viral enzymes NS3 protease and the RNA-dependent RNA polymerase NS5B. Here we describe the profile of BMS-790052, a small molecule inhibitor of the HCV NS5A protein that exhibits picomolar half-maximum effective concentrations (EC(50)) towards replicons expressing a broad range of HCV genotypes and the JFH-1 genotype 2a infectious virus in cell culture. In a phase I clinical trial in patients chronically infected with HCV, administration of a single 100-mg dose of BMS-790052 was associated with a 3.3 log(10) reduction in mean viral load measured 24 h post-dose that was sustained for an additional 120 h in two patients infected with genotype 1b virus. Genotypic analysis of samples taken at baseline, 24 and 144 h post-dose revealed that the major HCV variants observed had substitutions at amino-acid positions identified using the in vitro replicon system. These results provide the first clinical validation of an inhibitor of HCV NS5A, a protein with no known enzymatic function, as an approach to the suppression of virus replication that offers potential as part of a therapeutic regimen based on combinations of HCV inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gao, Min -- Nettles, Richard E -- Belema, Makonen -- Snyder, Lawrence B -- Nguyen, Van N -- Fridell, Robert A -- Serrano-Wu, Michael H -- Langley, David R -- Sun, Jin-Hua -- O'Boyle, Donald R 2nd -- Lemm, Julie A -- Wang, Chunfu -- Knipe, Jay O -- Chien, Caly -- Colonno, Richard J -- Grasela, Dennis M -- Meanwell, Nicholas A -- Hamann, Lawrence G -- England -- Nature. 2010 May 6;465(7294):96-100. doi: 10.1038/nature08960.

    RAF inhibitors transactivate RAF dimers and ERK signalling in cells with wild-type BRAF (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-02-25
    Description: Tumours with mutant BRAF are dependent on the RAF-MEK-ERK signalling pathway for their growth. We found that ATP-competitive RAF inhibitors inhibit ERK signalling in cells with mutant BRAF, but unexpectedly enhance signalling in cells with wild-type BRAF. Here we demonstrate the mechanistic basis for these findings. We used chemical genetic methods to show that drug-mediated transactivation of RAF dimers is responsible for paradoxical activation of the enzyme by inhibitors. Induction of ERK signalling requires direct binding of the drug to the ATP-binding site of one kinase of the dimer and is dependent on RAS activity. Drug binding to one member of RAF homodimers (CRAF-CRAF) or heterodimers (CRAF-BRAF) inhibits one protomer, but results in transactivation of the drug-free protomer. In BRAF(V600E) tumours, RAS is not activated, thus transactivation is minimal and ERK signalling is inhibited in cells exposed to RAF inhibitors. These results indicate that RAF inhibitors will be effective in tumours in which BRAF is mutated. Furthermore, because RAF inhibitors do not inhibit ERK signalling in other cells, the model predicts that they would have a higher therapeutic index and greater antitumour activity than mitogen-activated protein kinase (MEK) inhibitors, but could also cause toxicity due to MEK/ERK activation. These predictions have been borne out in a recent clinical trial of the RAF inhibitor PLX4032 (refs 4, 5). The model indicates that promotion of RAF dimerization by elevation of wild-type RAF expression or RAS activity could lead to drug resistance in mutant BRAF tumours. In agreement with this prediction, RAF inhibitors do not inhibit ERK signalling in cells that coexpress BRAF(V600E) and mutant RAS.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3178447/" 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/PMC3178447/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Poulikakos, Poulikos I -- Zhang, Chao -- Bollag, Gideon -- Shokat, Kevan M -- Rosen, Neal -- 1P01CA129243-02/CA/NCI NIH HHS/ -- 2R01EB001987/EB/NIBIB NIH HHS/ -- P01 CA129243-010002/CA/NCI NIH HHS/ -- R01 EB001987/EB/NIBIB NIH HHS/ -- U01 CA091178/CA/NCI NIH HHS/ -- U01 CA091178-01/CA/NCI NIH HHS/ -- England -- Nature. 2010 Mar 18;464(7287):427-30. doi: 10.1038/nature08902.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Molecular Pharmacology and Chemistry and Department of Medicine, Memorial Sloan-Kettering Cancer Center, New York, New York 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20179705" target="_blank"〉PubMed〈/a〉

    Description: Developing a human immunodeficiency virus (HIV) vaccine is critical to end the global acquired immunodeficiency syndrome (AIDS) epidemic, but many question whether this goal is achievable. Natural immunity is not protective, and despite immunogenicity of HIV vaccine candidates, human trials have exclusively yielded disappointing results. Nevertheless, there is an indication that success may be possible, but this will be dependent on understanding the antiviral immune response in unprecedented depth to identify and engineer the types of immunity required. Here we outline fundamental immunological questions that need to be answered to develop a protective HIV vaccine, and the immediate need to harness a much broader scientific community to achieve this goal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Virgin, Herbert W -- Walker, Bruce D -- England -- Nature. 2010 Mar 11;464(7286):224-31. doi: 10.1038/nature08898.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Washington University School of Medicine and Midwest Regional Center of Excellence for Biodefense and Emerging Infectious Disease Research, Campus Box 8118, 660 South Euclid Avenue, Saint Louis, Missouri 63110, USA. virgin@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20220841" target="_blank"〉PubMed〈/a〉

    Systems survey of endocytosis by multiparametric image analysis (2010)

    Details
    Publication Date: 2010-03-02
    Description: Endocytosis is a complex process fulfilling many cellular and developmental functions. Understanding how it is regulated and integrated with other cellular processes requires a comprehensive analysis of its molecular constituents and general design principles. Here, we developed a new strategy to phenotypically profile the human genome with respect to transferrin (TF) and epidermal growth factor (EGF) endocytosis by combining RNA interference, automated high-resolution confocal microscopy, quantitative multiparametric image analysis and high-performance computing. We identified several novel components of endocytic trafficking, including genes implicated in human diseases. We found that signalling pathways such as Wnt, integrin/cell adhesion, transforming growth factor (TGF)-beta and Notch regulate the endocytic system, and identified new genes involved in cargo sorting to a subset of signalling endosomes. A systems analysis by Bayesian networks further showed that the number, size, concentration of cargo and intracellular position of endosomes are not determined randomly but are subject to specific regulation, thus uncovering novel properties of the endocytic system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Collinet, Claudio -- Stoter, Martin -- Bradshaw, Charles R -- Samusik, Nikolay -- Rink, Jochen C -- Kenski, Denise -- Habermann, Bianca -- Buchholz, Frank -- Henschel, Robert -- Mueller, Matthias S -- Nagel, Wolfgang E -- Fava, Eugenio -- Kalaidzidis, Yannis -- Zerial, Marino -- England -- Nature. 2010 Mar 11;464(7286):243-9. doi: 10.1038/nature08779.

    Extrinsic regulation of pluripotent stem cells (2010)

    Details
    Publication Date: 2010-06-11
    Description: During early mammalian development, as the pluripotent cells that give rise to all of the tissues of the body proliferate and expand in number, they pass through transition states marked by a stepwise restriction in developmental potential and by changes in the expression of key regulatory genes. Recent findings show that cultured stem-cell lines derived from different stages of mouse development can mimic these transition states. They further reveal that there is a high degree of heterogeneity and plasticity in pluripotent populations in vitro and that these properties are modulated by extrinsic signalling. Understanding the extrinsic control of plasticity will guide efforts to use human pluripotent stem cells in research and therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pera, Martin F -- Tam, Patrick P L -- England -- Nature. 2010 Jun 10;465(7299):713-20. doi: 10.1038/nature09228.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Regenerative Medicine and Stem Cell Research, Keck School of Medicine, University of Southern California, Los Angeles, California 90033, USA. pera@usc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20535200" target="_blank"〉PubMed〈/a〉

    Epigenetic silencing of engineered L1 retrotransposition events in human embryonic carcinoma cells (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-08-06
    Description: Long interspersed element-1 (LINE-1 or L1) retrotransposition continues to affect human genome evolution. L1s can retrotranspose in the germline, during early development and in select somatic cells; however, the host response to L1 retrotransposition remains largely unexplored. Here we show that reporter genes introduced into the genome of various human embryonic carcinoma-derived cell lines (ECs) by L1 retrotransposition are rapidly and efficiently silenced either during or immediately after their integration. Treating ECs with histone deacetylase inhibitors rapidly reverses this silencing, and chromatin immunoprecipitation experiments revealed that reactivation of the reporter gene was correlated with changes in chromatin status at the L1 integration site. Under our assay conditions, rapid silencing was also observed when reporter genes were delivered into ECs by mouse L1s and a zebrafish LINE-2 element, but not when similar reporter genes were delivered into ECs by Moloney murine leukaemia virus or human immunodeficiency virus, suggesting that these integration events are silenced by distinct mechanisms. Finally, we demonstrate that subjecting ECs to culture conditions that promote differentiation attenuates the silencing of reporter genes delivered by L1 retrotransposition, but that differentiation, in itself, is not sufficient to reactivate previously silenced reporter genes. Thus, our data indicate that ECs differ from many differentiated cells in their ability to silence reporter genes delivered by L1 retrotransposition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3034402/" 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/PMC3034402/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garcia-Perez, Jose L -- Morell, Maria -- Scheys, Joshua O -- Kulpa, Deanna A -- Morell, Santiago -- Carter, Christoph C -- Hammer, Gary D -- Collins, Kathleen L -- O'Shea, K Sue -- Menendez, Pablo -- Moran, John V -- 5 P30 CA46592/CA/NCI NIH HHS/ -- GM-069985/GM/NIGMS NIH HHS/ -- GM060518/GM/NIGMS NIH HHS/ -- GM082970/GM/NIGMS NIH HHS/ -- NS-048187/NS/NINDS NIH HHS/ -- R01 DK62027/DK/NIDDK NIH HHS/ -- R01 GM060518/GM/NIGMS NIH HHS/ -- R01 GM060518-12/GM/NIGMS NIH HHS/ -- R01 GM082970/GM/NIGMS NIH HHS/ -- R01 GM082970-04/GM/NIGMS NIH HHS/ -- R01AI051198/AI/NIAID NIH HHS/ -- T32-GM08322/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Aug 5;466(7307):769-73. doi: 10.1038/nature09209.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Human Genetics, 1241 East Catherine Street, University of Michigan Medical School, Ann Arbor, Michigan 48109-5618, USA. josel.garcia.perez@juntadeandalucia.es〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20686575" target="_blank"〉PubMed〈/a〉

    Structural basis for the suppression of skin cancers by DNA polymerase eta (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-06-26
    Description: DNA polymerase eta (Poleta) is unique among eukaryotic polymerases in its proficient ability for error-free replication through ultraviolet-induced cyclobutane pyrimidine dimers, and inactivation of Poleta (also known as POLH) in humans causes the variant form of xeroderma pigmentosum (XPV). We present the crystal structures of Saccharomyces cerevisiae Poleta (also known as RAD30) in ternary complex with a cis-syn thymine-thymine (T-T) dimer and with undamaged DNA. The structures reveal that the ability of Poleta to replicate efficiently through the ultraviolet-induced lesion derives from a simple and yet elegant mechanism, wherein the two Ts of the T-T dimer are accommodated in an active site cleft that is much more open than in other polymerases. We also show by structural, biochemical and genetic analysis that the two Ts are maintained in a stable configuration in the active site via interactions with Gln 55, Arg 73 and Met 74. Together, these features define the basis for Poleta's action on ultraviolet-damaged DNA that is crucial in suppressing the mutagenic and carcinogenic consequences of sun exposure, thereby reducing the incidence of skin cancers in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3030469/" 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/PMC3030469/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Silverstein, Timothy D -- Johnson, Robert E -- Jain, Rinku -- Prakash, Louise -- Prakash, Satya -- Aggarwal, Aneel K -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 CA107650/CA/NCI NIH HHS/ -- R01 CA107650-39/CA/NCI NIH HHS/ -- R01 ES017767/ES/NIEHS NIH HHS/ -- R01 ES017767-01/ES/NIEHS NIH HHS/ -- England -- Nature. 2010 Jun 24;465(7301):1039-43. doi: 10.1038/nature09104.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural and Chemical Biology, Mount Sinai School of Medicine, Box 1677, 1425 Madison Avenue, New York, New York 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20577207" target="_blank"〉PubMed〈/a〉
