    Description: The ACT workshop "Enabling Sensor Interoperability" addressed the need for protocols at thehardware, firmware, and higher levels in order to attain instrument interoperability within and betweenocean observing systems. For the purpose of the workshop, participants spoke in tern of "instruments" rather than "sensors," defining an instrument as a device that contains one or more sensors or actuators and can convert signals from analog to digital.An increase in the abundance, variety, and complexity of instruments and observing systems suggeststhat effective standards would greatly improve "plug-and-work" capabilities. However, there are few standards or standards bodies that currently address instrument interoperability and configuration.Instrument interoperability issues span the length and breadth of these systems, from the measurementto the end user, including middleware services. There are three major components of instrumentinteroperability including physical, communication, and application/control layers. Participantsidentified the essential issues, current obstacles, and enabling technologies and standards,then came up with a series of short and long term solutions.The top three recommended actions, deemed achievable within 6 months of the release of thisreport are:A list of recommendations for enabling instrument interoperability should be put togetherand distributed to instrument developers.A recommendation for funding sources to achieve instrument interoperability should bedrafted. Funding should be provided (for example through NOPP or an IOOS request forproposals) to develop and demonstrate instrument interoperability technologies involvinginstrument manufacturers, observing system operators, and cyberinfrastructure groups.Program managers should be identified and made to understand that milestones for achievinginstrument interoperability include a) selection of a methodology for uniquely identifyingan instrument, b) development of a common protocol for automatic instrumentdiscovery, c) agreement on uniform methods for measurements, d) enablement of end usercontrolled power cycling, and e) implementation of a registry component for IDS and attributes.The top three recommended actions, deemed achievable within S years of the release of this reportare:An ocean observing interoperability standards body should be established that addresses standards for a) metadata, b) commands, c) protocols, d) processes, e) exclusivity, and f)naming authorities.[PDF contains 48 pages]

    Description: The co-organized Alliance for Coastal Technologies (ACT) and National Data Buoy Center (NDBC)Workshop "Meteorological Buoy Sensors Workshop" convened in Solomons, Maryland, April 19to 21,2006, sponsored by the University of Maryland Center for Environmental Science (UMCES)Chesapeake Bay Laboratory (CBL), an ACT partner institution. Participants from various sectorsincluding resource managers and industry representatives collaborated to focus on technologies andsensors that measure the near surface variables of wind speed and direction, barometric pressure,humidity and air temperature. The vendor list was accordingly targeted at companies that producedthese types of sensors. The managers represented a cross section of federal, regional and academicmarine observing interests from around the country. Workshop discussions focused on the challengesassociated with making marine meteorological observations in general and problems that werespecific to a particular variable. Discussions also explored methods to mitigate these challengesthrough the adoption of best practices, improved technologies and increased standardization. Someof the key workshop outcomes and recommendations included:0cean.US should establish a committee devoted to observations. The committee wouldhave a key role in developing observing standards.The community should adopt the target cost, reliability and performance standards draftedfor a typical meteorological package to be used by a regional observing system.A forum should be established to allow users and manufacturers to share best practicesfor the employment of marine meteorological sensors. The ACT website would host theforum.Federal activities that evaluate meteorological sensors should make their results publiclyavailable.ACT should extend their evaluation process to include meteorological sensors.A follow on workshop should be conducted that covers the observing of meteorologicalvariables not addressed by this workshop.

    Description: The Alliance for Coastal Technologies (ACT) convened a workshop on Evaluating Approaches and Technologies for Monitoring Organic Contaminants in the Aquatic Environment in Ann Arbor, MI on July 21-23, 2006. The primary objectives of this workshop were to: 1) identify the priority management information needs relative to organic contaminant loading; 2) explore themost appropriate approaches to estimating mass loading; and 3) evaluate the current status of thesensor technology. To meet these objectives, a mixture of leading research scientists, resourcemanagers, and industry representatives were brought together for a focused two-day workshop.The workshop featured four plenary talks followed by breakout sessions in which arranged groupsof participants where charged to respond to a series of focused discussion questions.At present, there are major concerns about the inadequacies in approaches and technologies forquantifying mass emissions and detection of organic contaminants for protecting municipal watersupplies and receiving waters. Managers use estimates of land-based contaminant loadings torivers, lakes, and oceans to assess relative risk among various contaminant sources, determinecompliance with regulatory standards, and define progress in source reduction. However, accuratelyquantifying contaminant loading remains a major challenge. Loading occurs over a range ofhydrologic conditions, requiring measurement technologies that can accommodate a broad rangeof ambient conditions. In addition, in situ chemical sensors that provide a means for acquiringcontinuous concentration measurements are still under development, particularly for organic contaminantsthat typically occur at low concentrations. Better approaches and strategies for estimatingcontaminant loading, including evaluations of both sampling design and sensor technologies,need to be identified. The following general recommendations were made in an effort to advancefuture organic contaminant monitoring:1. Improve the understanding of material balance in aquatic systems and the relationship betweenpotential surrogate measures (e.g., DOC, chlorophyll, particle size distribution) and target constituents.2. Develop continuous real-time sensors to be used by managers as screening measures and triggersfor more intensive monitoring.3. Pursue surrogate measures and indicators of organic pollutant contamination, such as CDOM,turbidity, or non-equilibrium partitioning.4. Develop continuous field-deployable sensors for PCBs, PAHs, pyrethroids, and emerging contaminantsof concern and develop strategies that couple sampling approaches with tools that incorporatesensor synergy (i.e., measure appropriate surrogates along with the dissolved organics toallow full mass emission estimation).[PDF contains 20 pages]

    Description: The Alliance for Coastal Technologies (ACT) Workshop "Making Oxygen MeasurementsRoutine Like Temperature" was convened in St. Petersburg, Florida, January 4th - 6th, 2006. Thisevent was sponsored by the University of South Florida (USF) College of Marine Science, anACT partner institution and co-hosted by the Ocean Research Interactive Observatory Networks(ORION). Participants from researcldacademia, resource management, industry, and engineeringsectors collaborated with the aim to foster ideas and information on how to make measuringdissolved oxygen a routine part of a coastal or open ocean observing system.Plans are in motion to develop large scale ocean observing systems as part of the US IntegratedOcean Observing System (100s; see http://ocean.us) and the NSF Ocean Observatory Initiative(001; see http://www.orionprogram.org/00I/default.hl). These systems will require biologicaland chemical sensors that can be deployed in large numbers, with high reliability, and forextended periods of time (years). It is also likely that the development cycle for new sensors issufficiently long enough that completely new instruments, which operate on novel principles,cannot be developed before these complex observing systems will be deployed. The most likelypath to development of robust, reliable, high endurance sensors in the near future is to movethe current generation of sensors to a much greater degree of readiness. The ACT OxygenSensor Technology Evaluation demonstrated two important facts that are related to the need forsensors. There is a suite of commercially available sensors that can, in some circumstances,generate high quality data; however, the evaluation also showed that none of the sensors were ableto generate high quality data in all circumstances for even one month time periods due tobiofouling issues.Many groups are attempting to use oxygen sensors in large observing programs; however, thereoften seems to be limited communication between these groups and they often do not have accessto sophisticated engineering resources. Instrument manufacturers also do not have sufficientresources to bring sensors, which are marketable, but of limited endurance or reliability, to ahigher state of readiness. The goal of this ACT/ORION Oxygen Sensor Workshop was to bringtogether a group of experienced oceanographers who are now deploying oxygen sensors inextended arrays along with a core of experienced and interested academic and industrialengineers, and manufacturers. The intended direction for this workshop was for this group toexchange information accumulated through a variety of sensor deployments, examine failuremechanisms and explore a variety of potential solutions to these problems. One anticipatedoutcome was for there to be focused recommendations to funding agencies on development needsand potential solutions for 02 sensors. (pdf contains 19 pages)

    Description: The Alliance for Coastal Technologies (ACT) Workshop on Towed Vehicles: Undulating PlatformsAs Tools for Mapping Coastal Processes and Water Quality Assessment was convenedFebruary 5-7,2007 at The Embassy Suites Hotel, Seaside, California and sponsored by the ACT-PacificCoast partnership at the Moss Landing Marine Laboratories (MLML). The TUV workshopwas co-chaired by Richard Burt (Chelsea Technology Group) and Stewart Lamerdin (MLMLMarine Operations). Invited participants were selected to provide a uniform representation of theacademic researchers, private sector product developers, and existing and potential data productusers from the resource management community to enable development of broad consensus opinionson the application of TUV platforms in coastal resource assessment and management.The workshop was organized to address recognized limitations of point-based monitoring programs,which, while providing valuable data, are incapable of describing the spatial heterogeneityand the extent of features distributed in the bulk solution. This is particularly true as surveysapproach the coastal zone where tidal and estuarine influences result in spatially and temporallyheterogeneous water masses and entrained biological components. Aerial or satellite based remotesensing can provide an assessment of the aerial extent of plumes and blooms, yet provide no informationregarding the third dimension of these features. Towed vehicles offer a cost-effectivesolution to this problem by providing platforms, which can sample in the horizontal, vertical, andtime-based domains. Towed undulating vehicles (henceforth TUVs) represent useful platformsfor event-response characterization. This workshop reviewed the current status of towed vehicletechnology focusing on limitations of depth, data telemetry, instrument power demands, and shiprequirements in an attempt to identify means to incorporate such technology more routinely inmonitoring and event-response programs. Specifically, the participants were charged to addressthe following: (1) Summarize the state of the art in TUV technologies; (2) Identify how TUVplatforms are used and how they can assist coastal managers in fulfilling their regulatory and managementresponsibilities; (3) Identify barriers and challenges to the application of TUV technologiesin management and research activities, and (4) Recommend a series of community actions toovercome identified barriers and challenges.A series of plenary presentation were provided to enhance subsequent breakout discussions bythe participants. Dave Nelson (University of Rhode Island) provided extensive summaries andreal-world assessment of the operational features of a variety of TUV platforms available in theUNOLs scientific fleet. Dr. Burke Hales (Oregon State University) described the modification ofTUV to provide a novel sampling platform for high resolution mapping of chemical distributionsin near real time. Dr. Sonia Batten (Sir Alister Hardy Foundation for Ocean Sciences) providedan overview on the deployment of specialized towed vehicles equipped with rugged continuousplankton recorders on ships of opportunity to obtain long-term, basin wide surveys of zooplanktoncommunity structure, enhancing our understanding of trends in secondary production in the upperocean.

    Description: The Alliance for Coastal Technologies (ACT) convened a Workshop on "Recent Developments in In Situ Nutrient Sensors: Applications and Future Directions" from 11-13 December, 2006. The workshop was held at the Georgia Coastal Center in Savannah, Georgia, with local coordination provided by the ACT partner at the Skidaway Institute of Oceanography (University System of Georgia). Since its formation in 2000, ACT partners have been conducting workshops on various sensor technologies and supporting infrastructure for sensor systems. This was the first workshop to revisit a topic area addressed previously by ACT.An earlier workshop on the "State of Technology in the Development and Application of Nutrient Sensors" was held in Savannah, Georgia from 10-12 March, 2003. Participants in the first workshop included representatives from management, industry, and research sectors. Among the topics addressed at the first workshop were characteristics of "ideal" in situ nutrient sensors, particularly with regard to applications in coastal marine waters.In contrast, the present workshop focused on the existing commercial solutions. The in situ nutrient sensor technologies that appear likely to remain the dominant commercial options for the next decade are reagent-based in situ auto-analyzers (or fluidics systems) and an optical approach (spectrophotometric measurement of nitrate). The number of available commercial systems has expanded since 2003, and community support for expanded application and further development of these technologies appears warranted. Application in coastal observing systems, including freshwater as well as estuarine and marine environments, was a focus of the present workshop.This included discussion of possible refinements for sustained deployments as part of integrated instrument packages and means to better promote broader use of nutrient sensors in observing system and management applications. The present workshop also made a number of specific recommendations concerning plans for a demonstration of in situ nutrient sensor technologies that ACT will be conducting in coordination with sensor manufacturers.[PDF contains 40 pages]

    Description: The Alliance for Coastal Technologies (ACT) convened a workshop on "Wave Sensor Technologies" in St. Petersburg, Florida on March 7-9, 2007, hosted by the University of South Florida (USF) College of Marine Science, an ACT partner institution. The primary objectives of thisworkshop were to: 1) define the present state of wave measurement technologies, 2) identify the major impediments to their advancement, and 3) make strategic recommendations for future development and on the necessary steps to integrate wave measurement sensors into operationalcoastal ocean observing systems. The participants were from various sectors, including research scientists, technology developers and industry providers, and technology users, such as operational coastal managers and coastal decision makers.Waves consistently are ranked as a critical variable for numerous coastal issues, from maritime transportation to beach erosion to habitat restoration. For the purposes of this workshop, the participants focused on measuring "wind waves" (i.e., waves on the water surface, generated by thewind, restored by gravity and existing between approximately 3 and 30-second periods), although it was recognized that a wide range of both forced and free waves exist on and in the oceans. Also, whereas the workshop put emphasis on the nearshore coastal component of wave measurements, the participants also stressed the importance of open ocean surface waves measurement. Wave sensor technologies that are presently available for both environments include bottom-mounted pressure gauges, surface following buoys, wave staffs, acoustic Doppler current profilers, and shore-based remote sensing radar instruments.One of the recurring themes of workshop discussions was the dichotomous nature of wave data users. The two separate groups, open ocean wave data users and the nearshore/coastal wave data users, have different requirements. Generally, the user requirements increase both in spatial/temporal resolution and precision as one moves closer to shore. Most ocean going mariners areadequately satisfied with measurements of wave period and height and a wave general direction.However, most coastal and nearshore users require at least the first five Fourier parameters ("First 5"): wave energy and the first four directional Fourier coefficients. Furthermore, wave research scientists would like sensors capable of providing measurements beyond the first four Fourier coefficients. It was debated whether or not high precision wave observations in one location cantake the place of a less precise measurement at a different location. This could be accomplished by advancing wave models and using wave models to extend data to nearby areas. However, the consensus was that models are no substitution for in situ wave data.[PDF contains 26 pages]

    Description: A three day workshop on turbidity measurements was held at the Hawaii Institute of MarineBiology from August 3 1 to September 2, 2005. The workshop was attended by 30 participantsfrom industry, coastal management agencies, and academic institutions. All groups recognizedcommon issues regarding the definition of turbidity, limitations of consistent calibration, and thelarge variety of instrumentation that nominally measure "turbidity." The major recommendations,in order of importance for the coastal monitoring community are listed below:1. The community of users in coastal ecosystems should tighten instrument designconfigurations to minimize inter-instrument variability, choosing a set of specificationsthat are best suited for coastal waters. The IS0 7027 design standard is not tight enough.Advice on these design criteria should be solicited through the ASTM as well as Federaland State regulatory agencies representing the majority of turbidity sensor end users.Parties interested in making turbidity measurements in coastal waters should developdesign specifications for these water types rather than relying on design standards madefor the analysis of drinking water.2. The coastal observing groups should assemble a community database relating output ofspecific sensors to different environmental parameters, so that the entire community ofusers can benefit from shared information. This would include an unbiased, parallel studyof different turbidity sensors, employing a variety of designs and configuration in thebroadest range of coastal environments.3. Turbidity should be used as a measure of relative change in water quality rather than anabsolute measure of water quality. Thus, this is a recommendation for managers todevelop their own local calibrations. See next recommendation.4. If the end user specifically wants to use a turbidity sensor to measure a specific waterquality parameter such as suspended particle concentration, then direct measurement ofthat water quality parameter is necessary to correlate with 'turbidity1 for a particularenvironment. These correlations, however, will be specific to the environment in whichthey are measured. This works because there are many environments in which watercomposition is relatively stable but varies in magnitude or concentration. (pdf contains 22 pages)

    Description: This Alliance for Coastal Technologies (ACT) workshop was convened to assess the availabilityand state of development of conductivity-temperature sensors that can meet the needs of coastalmonitoring and management communities. Rased on the discussion, there are presently a numberof commercial sensor options available, with a wide range of package configurations suitable fordeployment in a range of coastal environments. However, some of the central questions posedin the workshop planning documents were left somewhat unresolved. The workshop descriptionemphasized coastal management requirements and, in particular, whether less expensive, easilydeployed, lower-resolution instruments might serve many management needs. While several participantsexpressed interest in this class of conductivity-temperature sensors, based on input fromthe manufacturers, it is not clear that simply relaxing the present level of resolution of existing instrumentswill result in instruments of significantly lower unit cost. Conductivity-temperature sensorsare available near or under the $1,000 unit cost that was operationally defined at the workshopas a breakpoint for what might be considered to be a "low cost" sensor. For the manufacturers, akey consideration before undertaking the effort to develop lower cost sensors is whether there willbe a significant market. In terms of defining "low cost," it was also emphasized that the "life cyclecosts" for a given instrument must be considered (e.g., including personnel costs for deploymentand maintenance). An adequate market survey to demonstrate likely applications and a viablemarket for lower cost sensors is needed. Another topic for the workshop was the introductionto the proposed ACT verification for conductivity-temperature sensors. Following a summaryof the process as envisioned by ACT, initial feedback was solicited. Protocol development willbe pursued further in a workshop involving ACT personnel and conductivity-temperature sensormanufacturers.[PDF contains 28 pages]

    Description: The use of self-contained, low-maintenance sensor systems installed on commercial vessels isbecoming an important monitoring and scientific tool in many regions around the world. Thesesystems integrate data from meteorological and water quality sensors with GPS data into a datastream that is automatically transferred from ship to shore. To begin linking some of this developingexpertise, the Alliance for Coastal Technologies (ACT) and the European Coastal and OceanObserving Technology (ECOOT) organized a workshop on this topic in Southampton, UnitedKingdom, October 10-12, 2006. The participants included technology users, technology developers,and shipping representatives. They collaborated to identify sensors currently employed onintegrated systems, users of this data, limitations associated with these systems, and ways to overcomethese limitations. The group also identified additional technologies that could be employedon future systems and examined whether standard architectures and data protocols for integratedsystems should be established.Participants at the workshop defined 17 different parameters currently being measured by integratedsystems. They identified that diverse user groups utilize information from these systemsfrom resource management agencies, such as the Environmental Protection Agency (EPA), to localtourism groups and educational organizations. Among the limitations identified were instrumentcompatibility and interoperability, data quality control and quality assurance, and sensor calibrationandlor maintenance frequency. Standardization of these integrated systems was viewed to beboth advantageous and disadvantageous; while participants believed that standardization could bebeneficial on many levels, they also felt that users may be hesitant to purchase a suite of instrumentsfrom a single manufacturer; and that a "plug and play" system including sensors from multiplemanufactures may be difficult to achieve.A priority recommendation and conclusion for the general integrated sensor system communitywas to provide vessel operators with real-time access to relevant data (e.g., ambient temperatureand salinity to increase efficiency of water treatment systems and meteorological data for increasedvessel safety and operating efficiency) for broader system value. Simplified data displaysare also required for education and public outreach/awareness. Other key recommendations wereto encourage the use of integrated sensor packages within observing systems such as 100s andEuroGOOS, identify additional customers of sensor system data, and publish results of previouswork in peer-reviewed journals to increase agency and scientific awareness and confidence in thetechnology.Priority recommendations and conclusions for ACT entailed highlighting the value of integratedsensor systems for vessels of opportunity through articles in the popular press, and marine science.

    Description: The Alliance for Coastal Technologies (ACT) Workshop entitled "Technologies for MeasuringCurrents in Coastal Environments" was held in Portland, Maine, October 26-28, 2005, withsponsorship by the Gulf of Maine Ocean Observing System (GoMOOS), an ACT partnerorganization. The primary goals of the event were to summarize recent trends in nearshoreresearch and management applications for current meter technologies, identify how currentmeters can assist coastal managers to fulfill their regulatory and management objectives, and torecommend actions to overcome barriers to use of the technologies. The workshop was attendedby 25 participants representing state and federal environmental management agencies,manufacturers of current meter technologies, and researchers from academic institutions andprivate industry.Common themes that were discussed during the workshop included 1) advantages and limitationsof existing current measuring equipment, 2) reliability and ease of use with each instrument type,3) data decoding and interpretation procedures, and 4) mechanisms to facilitate better training andguidance to a broad user group. Seven key recommendations, which were ranked in order ofimportance during the last day of the workshop are listed below.1. Forums should be developed to facilitate the exchange of information among users andindustry:a) On-line forums that not only provide information on specific instruments andtechnologies, but also provide an avenue for the exchange of user experiences withvarious instruments (i.e. problems encountered, cautions, tips, advantages, etc). (seeReferences for manufacturer websites with links to application and technical forums atend of report)b) Regional training/meetings for operational managers to exchange ideas on methods formeasuring currents and evaluating data.c) Organize mini-meetings or tutorial sessions within larger conference venues.2. A committee of major stakeholders should be convened to develop common standards(similar to the Institute of Electrical and Electronics Engineers (IEEE) committee) thatenable users to switch sensors without losing software or display capabilities.

    Description: The Alliance for Coastal Technologies (ACT) held a Workshop on Sensor Technology forAssessing Groundwater-Surface Water Interactions in the Coastal Zone on March 7 to 9,2005 inSavannah, GA. The main goal of the workshop was to summarize the general parameters, whichhave been found to be useful in assessing groundwater-surface water (GW-SW) interactions in thecoastal zone. The workshop participants (Appendix I) were specifically charged with identifyingthe types of sensor systems, if any, that have been used to obtain time-series data and to makeknown which parameters may be the most amenable to the development/application of sensortechnology. The group consisted of researchers, industry representatives, and environmentalmanagers.Four general recommendations were made:1. Educate coastal managers and agencies on the importance of GW-SW interactions,keeping in mind that regulatory agencies are driven by a different set of rules thanresearchers: the focus is on understanding the significance of the problem and providingsolutions. ACT could facilitate this process in two ways. First, given that the researchliterature on this subject is fairly diffuse, ACT could provide links from its web site to factsheets or other literature. Second, ACT could organize a focused meeting for managersand/or agency groups.Encourage development of primary tools for quantifying flow. The most promisingtechnology in this respect is flow meters designed for flux chambers, mainly because theyshould be simple to use and can be made relatively inexpensively. However, it should bekept in mind that they provide only point measurements and several would need to bedeployed as a network in order to obtain reliable flow estimates. For evaluating systemwide GW-SW interactions, tools that integrate the signal over large areas would berequired. Suggestions include a user-friendly hydrogeologic models, keeping in mind thatfreshwater flow is not the entire story, or continuous radon monitors. Though the latterwould be slightly more difficult to use in terms of background knowledge, such aninstrument would be low power and easy to operate and maintain. ACT could facilitatethis recommendation by identifying funding opportunities on its web site and/orperforming evaluations of existing technologies that could be summarized on the web site.

    Description: The Alliance for Coastal Technologies (ACT) Workshop on Optical Remote Sensing of CoastalHabitats was convened January 9-11, 2006 at Moss Landing Marine Laboratories in MossLanding, California, sponsored by the ACT West Coast regional partnership comprised of theMoss Landing Marine Laboratories (MLML) and the Monterey Bay Aquarium Research Institute(MBARI). The "Optical Remote Sensing of Coastal Habitats" (ORS) Workshop completesACT'S Remote Sensing Technology series by building upon the success of ACT'S West CoastRegional Partner Workshop "Acoustic Remote Sensing Technologies for Coastal Imaging andResource Assessment" (ACT 04-07). Drs. Paul Bissett of the Florida Environmental ResearchInstitute (FERI) and Scott McClean of Satlantic, Inc. were the ORS workshop co-chairs. Invitedparticipants were selected to provide a uniform representation of the academic researchers, privatesector product developers, and existing and potential data product users from the resource managementcommunity to enable development of broad consensus opinions on the role of ORS technologiesin coastal resource assessment and management.The workshop was organized to examine the current state of multi- and hyper-spectral imagingtechnologies with the intent to assess the current limits on their routine application for habitat classificationand resource monitoring of coastal watersheds, nearshore shallow water environments,and adjacent optically deep waters. Breakout discussions focused on the capabilities, advantages,and limitations of the different technologies (e.g., spectral & spatial resolution), as well as practicalissues related to instrument and platform availability, reliability, hardware, software, and technicalskill levels required to exploit the data products generated by these instruments. Specifically,the participants were charged to address the following: (1) Identify the types of ORS data productscurrently used for coastal resource assessment and how they can assist coastal managers in fulfillingtheir regulatory and management responsibilities; (2) Identify barriers and challenges to theapplication of ORS technologies in management and research activities; (3) Recommend a seriesof community actions to overcome identified barriers and challenges.Plenary presentations by Drs. Curtiss 0. Davis (Oregon State University) and Stephan Lataille(ITRES Research, Ltd.) provided background summaries on the varieties of ORS technologiesavailable, deployment platform options, and tradeoffs for application of ORS data products withspecific applications to the assessment of coastal zone water quality and habitat characterization.Dr. Jim Aiken (CASIX) described how multiscale ground-truth measurements were essential fordeveloping robust assessment of modeled biogeochemical interpretations derived from opticallybased earth observation data sets. While continuing improvements in sensor spectral resolution,signal to noise and dynamic range coupled with sensor-integrated GPS, improved processing algorithmsfor georectification, and atmospheric correction have made ORS data products invaluablesynoptic tools for oceanographic research, their adoption as management tools has lagged. SethBlitch (Apalachicola National Estuarine Research Reserve) described the obvious needs for, yetsubstantial challenges hindering the adoption of advanced spectroscopic imaging data productsto supplement the current dominance of digital ortho-quad imagery by the resource managementcommunity, especially when they impinge on regulatory issues.

    Description: The Alliance for Coastal Technologies (ACT) Workshop on Trace Metal Sensors for CoastalMonitoring was convened April 11-13, 2005 at the Embassy Suites in Seaside, California withpartnership from Moss Landing Marine Laboratories (MLML) and the Monterey Bay AquariumResearch Institute (MBARI).Trace metals play many important roles in marine ecosystems. Due to their extreme toxicity, theeffects of copper, cadmium and certain organo-metallinc compounds (such as tributyltin andmethylmercury) have received much attention. Lately, the sublethal effects of metals onphytoplankton biochemistry, and in some cases the expression of neurotoxins (Domoic acid),have been shown to be important environmental forcing functions determining the compositionand gene expression in some groups. More recently the role of iron in controlling phytoplanktongrowth has led to an understanding of trace metal limitation in coastal systems. Although metalsplay an important role at many different levels, few technologies exist to provide rapid assessmentof metal concentrations or metal speciation in the coastal zone where metal-induced toxicity orpotential stimulation of harmful algal blooms, can have major economic impacts. This workshopfocused on the state of on-site and in situ trace element detection technologies, in terms of whatis currently working well and what is needed to effectively inform coastal zone managers, as wellas guide adaptive scientific sampling of the coastal zone. Specifically the goals of this workshopwere to: 1) summarize current regional requirements and future targets for metal monitoring infreshwater, estuarine and coastal environments; 2) evaluate the current status of metal sensors andpossibilities for leveraging emerging technologies for expanding detection limits and targetelements; and 3) help identify critical steps needed for and limits to operational deployment ofmetal sensors as part of routine water quality monitoring efforts.Following a series of breakout group discussions and overview talks on metal monitoringregulatory issues, analytical techniques and market requirements, workshop participants madeseveral recommendations for steps needed to foster development of in situ metal monitoringcapacities:1. Increase scientific and public awareness of metals of environmental and biologicalconcern and their impacts in aquatic environments. Inform scientific and publiccommunities regarding actual levels of trace metals in natural and perturbed systems.2. Identify multiple use applications (e.g., industrial waste steam and drinking water qualitymonitoring) to support investments in metal sensor development. (pdf contains 27 pages)

Participants included representatives fromstate and federal environmental management agencies as well as research institutions, many ofwhom are currently using this technology in their research and management applications.Manufacturers and developers of fluorometric measuring systems also attended the meeting.The Workshop attendees discussed the historical and present uses of fluorometry technology andidentified the great potential for its use by coastal managers to fulfill their regulatory andmanagement objectives. Participants also identified some of the challenges associated with thecorrect use of Fluorometers to estimate biomass and the rate of primary productivity. TheWorkshop concluded that in order to expand the existing use of fluorometers in both academicand resource management disciplines, several issues concerning data collection, instrumentcalibration, and data interpretation needed to be addressed. Participants identified twelverecommendations, the top five of which are listed below:Recommendations1) Develop a "Guide" that describes the most important aspects of fluorescencemeasurements. This guide should be written by an expert party, with both research andindustry input, and should be distributed by all manufacturers with theirinstrumentation. The guide should also be made available on the ACT website as wellas those of other relevant organizations. The guide should include discussions on thefollowing topics:The benefits of using fluorometers in research and resource managementapplications;What fluorometers can and cannot provide in terms of measurements;The necessary assumptions required before applying fluorometry;Characterization and calibration of fluorometers; (pdf contains 32 pages)

    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〉

    RANK ligand mediates progestin-induced mammary epithelial proliferation and carcinogenesis (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-10-01
    Description: RANK ligand (RANKL), a TNF-related molecule, is essential for osteoclast formation, function and survival through interaction with its receptor RANK. Mammary glands of RANK- and RANKL-deficient mice develop normally during sexual maturation, but fail to form lobuloalveolar structures during pregnancy because of defective proliferation and increased apoptosis of mammary epithelium. It has been shown that RANKL is responsible for the major proliferative response of mouse mammary epithelium to progesterone during mammary lactational morphogenesis, and in mouse models, manipulated to induce activation of the RANK/RANKL pathway in the absence of strict hormonal control, inappropriate mammary proliferation is observed. However, there is no evidence so far of a functional contribution of RANKL to tumorigenesis. Here we show that RANK and RANKL are expressed within normal, pre-malignant and neoplastic mammary epithelium, and using complementary gain-of-function (mouse mammary tumour virus (MMTV)-RANK transgenic mice) and loss-of function (pharmacological inhibition of RANKL) approaches, define a direct contribution of this pathway in mammary tumorigenesis. Accelerated pre-neoplasias and increased mammary tumour formation were observed in MMTV-RANK transgenic mice after multiparity or treatment with carcinogen and hormone (progesterone). Reciprocally, selective pharmacological inhibition of RANKL attenuated mammary tumour development not only in hormone- and carcinogen-treated MMTV-RANK and wild-type mice, but also in the MMTV-neu transgenic spontaneous tumour model. The reduction in tumorigenesis upon RANKL inhibition was preceded by a reduction in pre-neoplasias as well as rapid and sustained reductions in hormone- and carcinogen-induced mammary epithelial proliferation and cyclin D1 levels. Collectively, our results indicate that RANKL inhibition is acting directly on hormone-induced mammary epithelium at early stages in tumorigenesis, and the permissive contribution of progesterone to increased mammary cancer incidence is due to RANKL-dependent proliferative changes in the mammary epithelium. The current study highlights a potential role for RANKL inhibition in the management of proliferative breast disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gonzalez-Suarez, Eva -- Jacob, Allison P -- Jones, Jon -- Miller, Robert -- Roudier-Meyer, Martine P -- Erwert, Ryan -- Pinkas, Jan -- Branstetter, Dan -- Dougall, William C -- England -- Nature. 2010 Nov 4;468(7320):103-7. doi: 10.1038/nature09495.

    A population-specific HTR2B stop codon predisposes to severe impulsivity (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-12-24
    Description: Impulsivity, describing action without foresight, is an important feature of several psychiatric diseases, suicidality and violent behaviour. The complex origins of impulsivity hinder identification of the genes influencing it and the diseases with which it is associated. Here we perform exon-focused sequencing of impulsive individuals in a founder population, targeting fourteen genes belonging to the serotonin and dopamine domain. A stop codon in HTR2B was identified that is common (minor allele frequency 〉 1%) but exclusive to Finnish people. Expression of the gene in the human brain was assessed, as well as the molecular functionality of the stop codon, which was associated with psychiatric diseases marked by impulsivity in both population and family-based analyses. Knockout of Htr2b increased impulsive behaviours in mice, indicative of predictive validity. Our study shows the potential for identifying and tracing effects of rare alleles in complex behavioural phenotypes using founder populations, and indicates a role for HTR2B in impulsivity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3183507/" 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/PMC3183507/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bevilacqua, Laura -- Doly, Stephane -- Kaprio, Jaakko -- Yuan, Qiaoping -- Tikkanen, Roope -- Paunio, Tiina -- Zhou, Zhifeng -- Wedenoja, Juho -- Maroteaux, Luc -- Diaz, Silvina -- Belmer, Arnaud -- Hodgkinson, Colin A -- Dell'osso, Liliana -- Suvisaari, Jaana -- Coccaro, Emil -- Rose, Richard J -- Peltonen, Leena -- Virkkunen, Matti -- Goldman, David -- AA-09203/AA/NIAAA NIH HHS/ -- AA-12502/AA/NIAAA NIH HHS/ -- Z01 AA000301-09/Intramural NIH HHS/ -- Z01 AA000301-10/Intramural NIH HHS/ -- Z99 AA999999/Intramural NIH HHS/ -- England -- Nature. 2010 Dec 23;468(7327):1061-6. doi: 10.1038/nature09629.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Neurogenetics, National Institute on Alcohol Abuse and Alcoholism, NIH, Rockville, Maryland 20852, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21179162" target="_blank"〉PubMed〈/a〉

    MICU1 encodes a mitochondrial EF hand protein required for Ca(2+) uptake (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-08-10
    Description: Mitochondrial calcium uptake has a central role in cell physiology by stimulating ATP production, shaping cytosolic calcium transients and regulating cell death. The biophysical properties of mitochondrial calcium uptake have been studied in detail, but the underlying proteins remain elusive. Here we use an integrative strategy to predict human genes involved in mitochondrial calcium entry based on clues from comparative physiology, evolutionary genomics and organelle proteomics. RNA interference against 13 top candidates highlighted one gene, CBARA1, that we call hereafter mitochondrial calcium uptake 1 (MICU1). Silencing MICU1 does not disrupt mitochondrial respiration or membrane potential but abolishes mitochondrial calcium entry in intact and permeabilized cells, and attenuates the metabolic coupling between cytosolic calcium transients and activation of matrix dehydrogenases. MICU1 is associated with the mitochondrial inner membrane and has two canonical EF hands that are essential for its activity, indicating a role in calcium sensing. MICU1 represents the founding member of a set of proteins required for high-capacity mitochondrial calcium uptake. Its discovery may lead to the complete molecular characterization of mitochondrial calcium uptake pathways, and offers genetic strategies for understanding their contribution to normal physiology and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2977980/" 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/PMC2977980/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perocchi, Fabiana -- Gohil, Vishal M -- Girgis, Hany S -- Bao, X Robert -- McCombs, Janet E -- Palmer, Amy E -- Mootha, Vamsi K -- DK080261/DK/NIDDK NIH HHS/ -- GM0077465/GM/NIGMS NIH HHS/ -- GM084027/GM/NIGMS NIH HHS/ -- R01 GM077465/GM/NIGMS NIH HHS/ -- R01 GM077465-01A1/GM/NIGMS NIH HHS/ -- R01 GM077465-02/GM/NIGMS NIH HHS/ -- R01 GM077465-03/GM/NIGMS NIH HHS/ -- R01 GM077465-04/GM/NIGMS NIH HHS/ -- R01 GM077465-05/GM/NIGMS NIH HHS/ -- R01 GM077465-06/GM/NIGMS NIH HHS/ -- R01 GM084027/GM/NIGMS NIH HHS/ -- R24 DK080261/DK/NIDDK NIH HHS/ -- R24 DK080261-04/DK/NIDDK NIH HHS/ -- TR2 GM08759/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Sep 16;467(7313):291-6. doi: 10.1038/nature09358.

    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.

    Reprogramming towards pluripotency requires AID-dependent DNA demethylation (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-23
    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〉

    Oxidative stress induces angiogenesis by activating TLR2 with novel endogenous ligands (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-10-12
    Description: Reciprocity of inflammation, oxidative stress and neovascularization is emerging as an important mechanism underlying numerous processes from tissue healing and remodelling to cancer progression. Whereas the mechanism of hypoxia-driven angiogenesis is well understood, the link between inflammation-induced oxidation and de novo blood vessel growth remains obscure. Here we show that the end products of lipid oxidation, omega-(2-carboxyethyl)pyrrole (CEP) and other related pyrroles, are generated during inflammation and wound healing and accumulate at high levels in ageing tissues in mice and in highly vascularized tumours in both murine and human melanoma. The molecular patterns of carboxyalkylpyrroles are recognized by Toll-like receptor 2 (TLR2), but not TLR4 or scavenger receptors on endothelial cells, leading to an angiogenic response that is independent of vascular endothelial growth factor. CEP promoted angiogenesis in hindlimb ischaemia and wound healing models through MyD88-dependent TLR2 signalling. Neutralization of endogenous carboxyalkylpyrroles impaired wound healing and tissue revascularization and diminished tumour angiogenesis. Both TLR2 and MyD88 are required for CEP-induced stimulation of Rac1 and endothelial migration. Taken together, these findings establish a new function of TLR2 as a sensor of oxidation-associated molecular patterns, providing a key link connecting inflammation, oxidative stress, innate immunity and angiogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2990914/" 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/PMC2990914/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉West, Xiaoxia Z -- Malinin, Nikolay L -- Merkulova, Alona A -- Tischenko, Mira -- Kerr, Bethany A -- Borden, Ernest C -- Podrez, Eugene A -- Salomon, Robert G -- Byzova, Tatiana V -- CA126847/CA/NCI NIH HHS/ -- GM021249/GM/NIGMS NIH HHS/ -- HL071625/HL/NHLBI NIH HHS/ -- HL073311/HL/NHLBI NIH HHS/ -- HL077213/HL/NHLBI NIH HHS/ -- R01 HL071625/HL/NHLBI NIH HHS/ -- R01 HL071625-07/HL/NHLBI NIH HHS/ -- R01 HL071625-08/HL/NHLBI NIH HHS/ -- R01 HL077213/HL/NHLBI NIH HHS/ -- England -- Nature. 2010 Oct 21;467(7318):972-6. doi: 10.1038/nature09421.

    Functional genomic screen for modulators of ciliogenesis and cilium length (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-04-16
    Description: Primary cilia are evolutionarily conserved cellular organelles that organize diverse signalling pathways. Defects in the formation or function of primary cilia are associated with a spectrum of human diseases and developmental abnormalities. Genetic screens in model organisms have discovered core machineries of cilium assembly and maintenance. However, regulatory molecules that coordinate the biogenesis of primary cilia with other cellular processes, including cytoskeletal organization, vesicle trafficking and cell-cell adhesion, remain to be identified. Here we report the results of a functional genomic screen using RNA interference (RNAi) to identify human genes involved in ciliogenesis control. The screen identified 36 positive and 13 negative ciliogenesis modulators, which include molecules involved in actin dynamics and vesicle trafficking. Further investigation demonstrated that blocking actin assembly facilitates ciliogenesis by stabilizing the pericentrosomal preciliary compartment (PPC), a previously uncharacterized compact vesiculotubular structure storing transmembrane proteins destined for cilia during the early phase of ciliogenesis. The PPC was labelled by recycling endosome markers. Moreover, knockdown of modulators that are involved in the endocytic recycling pathway affected the formation of the PPC as well as ciliogenesis. Our results uncover a critical regulatory step that couples actin dynamics and endocytic recycling with ciliogenesis, and also provides potential target molecules for future study.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2929961/" 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/PMC2929961/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Joon -- Lee, Ji Eun -- Heynen-Genel, Susanne -- Suyama, Eigo -- Ono, Keiichiro -- Lee, Kiyoung -- Ideker, Trey -- Aza-Blanc, Pedro -- Gleeson, Joseph G -- GM070743/GM/NIGMS NIH HHS/ -- P30 CA023100/CA/NCI NIH HHS/ -- P30 CA23100/CA/NCI NIH HHS/ -- P30 NS047101/NS/NINDS NIH HHS/ -- P30 NS057096/NS/NINDS NIH HHS/ -- R01 GM070743/GM/NIGMS NIH HHS/ -- R01 NS052455/NS/NINDS NIH HHS/ -- R01 NS052455-05/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Apr 15;464(7291):1048-51. doi: 10.1038/nature08895.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurosciences, Institute for Genomic Medicine, Howard Hughes Medical Institute, University of California San Diego, La Jolla, California 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20393563" target="_blank"〉PubMed〈/a〉
