    Description: Blooms of toxic or harmful microalgae, commonly called "red tides," represent a significant and expanding threat to human health and fisheries resources throughout the United States and the world. Ecological, aesthetic, and public health impacts include: mass mortalities of wild and farmed fish and shellfish, human intoxication and death from the consumption of contaminated shellfish or fish, alterations of marine food webs through adverse effects on larvae and other life history stages of commercial fish species, the noxious smell and appearance of algae accumulated in nearshore waters or deposited on beaches, and mass mortalities of marine mammals, seabirds, and other animals. In this report, we provide an estimate of the economic impacts of HABs in the United States from events where such impacts were measurable with a fair degree of confidence during the interval 1987-92. The total economic impact averaged $49 million per year, with public health impacts representing the largest component (45 percent). Commercial fisheries impacts were the next largest (37 percent of the total), while recreation/tourism accounted for 13 percent, and monitoring/management impacts 4 percent. These estimates are highly conservative, as many economic costs or impacts from HABs could not be estimated.

    Description: All cancers carry somatic mutations. A subset of these somatic alterations, termed driver mutations, confer selective growth advantage and are implicated in cancer development, whereas the remainder are passengers. Here we have sequenced the genomes of a malignant melanoma and a lymphoblastoid cell line from the same person, providing the first comprehensive catalogue of somatic mutations from an individual cancer. The catalogue provides remarkable insights into the forces that have shaped this cancer genome. The dominant mutational signature reflects DNA damage due to ultraviolet light exposure, a known risk factor for malignant melanoma, whereas the uneven distribution of mutations across the genome, with a lower prevalence in gene footprints, indicates that DNA repair has been preferentially deployed towards transcribed regions. The results illustrate the power of a cancer genome sequence to reveal traces of the DNA damage, repair, mutation and selection processes that were operative years before the cancer became symptomatic.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3145108/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3145108/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pleasance, Erin D -- Cheetham, R Keira -- Stephens, Philip J -- McBride, David J -- Humphray, Sean J -- Greenman, Chris D -- Varela, Ignacio -- Lin, Meng-Lay -- Ordonez, Gonzalo R -- Bignell, Graham R -- Ye, Kai -- Alipaz, Julie -- Bauer, Markus J -- Beare, David -- Butler, Adam -- Carter, Richard J -- Chen, Lina -- Cox, Anthony J -- Edkins, Sarah -- Kokko-Gonzales, Paula I -- Gormley, Niall A -- Grocock, Russell J -- Haudenschild, Christian D -- Hims, Matthew M -- James, Terena -- Jia, Mingming -- Kingsbury, Zoya -- Leroy, Catherine -- Marshall, John -- Menzies, Andrew -- Mudie, Laura J -- Ning, Zemin -- Royce, Tom -- Schulz-Trieglaff, Ole B -- Spiridou, Anastassia -- Stebbings, Lucy A -- Szajkowski, Lukasz -- Teague, Jon -- Williamson, David -- Chin, Lynda -- Ross, Mark T -- Campbell, Peter J -- Bentley, David R -- Futreal, P Andrew -- Stratton, Michael R -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- 093867/Wellcome Trust/United Kingdom -- England -- Nature. 2010 Jan 14;463(7278):191-6. doi: 10.1038/nature08658.

    Description: Although information storage in the central nervous system is thought to be primarily mediated by various forms of synaptic plasticity, other mechanisms, such as modifications in membrane excitability, are available. Local dendritic spikes are nonlinear voltage events that are initiated within dendritic branches by spatially clustered and temporally synchronous synaptic input. That local spikes selectively respond only to appropriately correlated input allows them to function as input feature detectors and potentially as powerful information storage mechanisms. However, it is currently unknown whether any effective form of local dendritic spike plasticity exists. Here we show that the coupling between local dendritic spikes and the soma of rat hippocampal CA1 pyramidal neurons can be modified in a branch-specific manner through an N-methyl-d-aspartate receptor (NMDAR)-dependent regulation of dendritic Kv4.2 potassium channels. These data suggest that compartmentalized changes in branch excitability could store multiple complex features of synaptic input, such as their spatio-temporal correlation. We propose that this 'branch strength potentiation' represents a previously unknown form of information storage that is distinct from that produced by changes in synaptic efficacy both at the mechanistic level and in the type of information stored.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Losonczy, Attila -- Makara, Judit K -- Magee, Jeffrey C -- England -- Nature. 2008 Mar 27;452(7186):436-41. doi: 10.1038/nature06725.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Janelia Farm Research Campus, 19700 Helix Dr Ashburn, Virginia 20147, USA. losonczya@janelia.hhmi.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18368112" target="_blank"〉PubMed〈/a〉

    Description: Many tumour cells have elevated rates of glucose uptake but reduced rates of oxidative phosphorylation. This persistence of high lactate production by tumours in the presence of oxygen, known as aerobic glycolysis, was first noted by Otto Warburg more than 75 yr ago. How tumour cells establish this altered metabolic phenotype and whether it is essential for tumorigenesis is as yet unknown. Here we show that a single switch in a splice isoform of the glycolytic enzyme pyruvate kinase is necessary for the shift in cellular metabolism to aerobic glycolysis and that this promotes tumorigenesis. Tumour cells have been shown to express exclusively the embryonic M2 isoform of pyruvate kinase. Here we use short hairpin RNA to knockdown pyruvate kinase M2 expression in human cancer cell lines and replace it with pyruvate kinase M1. Switching pyruvate kinase expression to the M1 (adult) isoform leads to reversal of the Warburg effect, as judged by reduced lactate production and increased oxygen consumption, and this correlates with a reduced ability to form tumours in nude mouse xenografts. These results demonstrate that M2 expression is necessary for aerobic glycolysis and that this metabolic phenotype provides a selective growth advantage for tumour cells in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Christofk, Heather R -- Vander Heiden, Matthew G -- Harris, Marian H -- Ramanathan, Arvind -- Gerszten, Robert E -- Wei, Ru -- Fleming, Mark D -- Schreiber, Stuart L -- Cantley, Lewis C -- R01 GM056203/GM/NIGMS NIH HHS/ -- T32 CA009172/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 Mar 13;452(7184):230-3. doi: 10.1038/nature06734.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Systems Biology, Harvard Medical School, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18337823" target="_blank"〉PubMed〈/a〉

    Description: We often face alternatives that we are free to choose between. Planning movements to select an alternative involves several areas in frontal and parietal cortex that are anatomically connected into long-range circuits. These areas must coordinate their activity to select a common movement goal, but how neural circuits make decisions remains poorly understood. Here we simultaneously record from the dorsal premotor area (PMd) in frontal cortex and the parietal reach region (PRR) in parietal cortex to investigate neural circuit mechanisms for decision making. We find that correlations in spike and local field potential (LFP) activity between these areas are greater when monkeys are freely making choices than when they are following instructions. We propose that a decision circuit featuring a sub-population of cells in frontal and parietal cortex may exchange information to coordinate activity between these areas. Cells participating in this decision circuit may influence movement choices by providing a common bias to the selection of movement goals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2728060/" 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/PMC2728060/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pesaran, Bijan -- Nelson, Matthew J -- Andersen, Richard A -- R01 EY007492/EY/NEI NIH HHS/ -- R01 EY007492-19/EY/NEI NIH HHS/ -- England -- Nature. 2008 May 15;453(7193):406-9. doi: 10.1038/nature06849.

    Description: Sound communication plays a vital role in frog reproduction, in which vocal advertisement is generally the domain of males. Females are typically silent, but in a few anuran species they can produce a feeble reciprocal call or rapping sounds during courtship. Males of concave-eared torrent frogs (Odorrana tormota) have demonstrated ultrasonic communication capacity. Although females of O. tormota have an unusually well-developed vocal production system, it is unclear whether or not they produce calls or are only passive partners in a communication system dominated by males. Here we show that before ovulation, gravid females of O. tormota emit calls that are distinct from males' advertisement calls, having higher fundamental frequencies and harmonics and shorter call duration. In the field and in a quiet, darkened indoor arena, these female calls evoke vocalizations and extraordinarily precise positive phonotaxis (a localization error of 〈1 degrees ), rivalling that of vertebrates with the highest localization acuity (barn owls, dolphins, elephants and humans). The localization accuracy of O. tormota is remarkable in light of their small head size (interaural distance of 〈1 cm), and suggests an additional selective advantage of high-frequency hearing beyond the ability to avoid masking by low-frequency background noise.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, Jun-Xian -- Feng, Albert S -- Xu, Zhi-Min -- Yu, Zu-Lin -- Arch, Victoria S -- Yu, Xin-Jian -- Narins, Peter M -- England -- Nature. 2008 Jun 12;453(7197):914-6. doi: 10.1038/nature06719.

    Description: As perceived by Darwin, evolutionary adaptation by the processes of mutation and selection is difficult to understand for complex features that are the product of numerous traits acting in concert, for example the eye or the apparatus of flight. Typically, mutations simultaneously affect multiple phenotypic characters. This phenomenon is known as pleiotropy. The impact of pleiotropy on evolution has for decades been the subject of formal analysis. Some authors have suggested that pleiotropy can impede evolutionary progress (a so-called 'cost of complexity'). The plausibility of various phenomena attributed to pleiotropy depends on how many traits are affected by each mutation and on our understanding of the correlation between the number of traits affected by each gene substitution and the size of mutational effects on individual traits. Here we show, by studying pleiotropy in mice with the use of quantitative trait loci (QTLs) affecting skeletal characters, that most QTLs affect a relatively small subset of traits and that a substitution at a QTL has an effect on each trait that increases with the total number of traits affected. This suggests that evolution of higher organisms does not suffer a 'cost of complexity' because most mutations affect few traits and the size of the effects does not decrease with pleiotropy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wagner, Gunter P -- Kenney-Hunt, Jane P -- Pavlicev, Mihaela -- Peck, Joel R -- Waxman, David -- Cheverud, James M -- England -- Nature. 2008 Mar 27;452(7186):470-2. doi: 10.1038/nature06756.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Yale University, New Haven, Connecticut 06520-8106, USA. gunter.wagner@yale.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18368117" target="_blank"〉PubMed〈/a〉

    Description: Genetic data from two or more species provide information about the process of speciation. In their analysis of DNA from humans, chimpanzees, gorillas, orangutans and macaques (HCGOM), Patterson et al. suggest that the apparently short divergence time between humans and chimpanzees on the X chromosome is explained by a massive interspecific hybridization event in the ancestry of these two species. However, Patterson et al. do not statistically test their own null model of simple speciation before concluding that speciation was complex, and--even if the null model could be rejected--they do not consider other explanations of a short divergence time on the X chromosome. These include natural selection on the X chromosome in the common ancestor of humans and chimpanzees, changes in the ratio of male-to-female mutation rates over time, and less extreme versions of divergence with gene flow (see ref. 2, for example). I therefore believe that their claim of hybridization is unwarranted.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wakeley, John -- England -- Nature. 2008 Mar 13;452(7184):E3-4; discussion E4. doi: 10.1038/nature06805.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismic and Evolutionary Biology, Harvard University, 16 Divinity Avenue, Cambridge, Massachusetts 02138, USA. wakeley@fas.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18337768" target="_blank"〉PubMed〈/a〉

    Description: Relapse to cocaine use after prolonged abstinence is an important clinical problem. This relapse is often induced by exposure to cues associated with cocaine use. To account for the persistent propensity for relapse, it has been suggested that cue-induced cocaine craving increases over the first several weeks of abstinence and remains high for extended periods. We and others identified an analogous phenomenon in rats that was termed 'incubation of cocaine craving': time-dependent increases in cue-induced cocaine-seeking over the first months after withdrawal from self-administered cocaine. Cocaine-seeking requires the activation of glutamate projections that excite receptors for alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) in the nucleus accumbens. Here we show that the number of synaptic AMPA receptors in the accumbens is increased after prolonged withdrawal from cocaine self-administration by the addition of new AMPA receptors lacking glutamate receptor 2 (GluR2). Furthermore, we show that these new receptors mediate the incubation of cocaine craving. Our results indicate that GluR2-lacking AMPA receptors could be a new target for drug development for the treatment of cocaine addiction. We propose that after prolonged withdrawal from cocaine, increased numbers of synaptic AMPA receptors combined with the higher conductance of GluR2-lacking AMPA receptors causes increased reactivity of accumbens neurons to cocaine-related cues, leading to an intensification of drug craving and relapse.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2574981/" 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/PMC2574981/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Conrad, Kelly L -- Tseng, Kuei Y -- Uejima, Jamie L -- Reimers, Jeremy M -- Heng, Li-Jun -- Shaham, Yavin -- Marinelli, Michela -- Wolf, Marina E -- DA00453/DA/NIDA NIH HHS/ -- DA015835/DA/NIDA NIH HHS/ -- DA020654/DA/NIDA NIH HHS/ -- DA09621/DA/NIDA NIH HHS/ -- Z01 DA000434-08/Intramural NIH HHS/ -- England -- Nature. 2008 Jul 3;454(7200):118-21. doi: 10.1038/nature06995.

    Description: Human primordial germ cells and mouse neonatal and adult germline stem cells are pluripotent and show similar properties to embryonic stem cells. Here we report the successful establishment of human adult germline stem cells derived from spermatogonial cells of adult human testis. Cellular and molecular characterization of these cells revealed many similarities to human embryonic stem cells, and the germline stem cells produced teratomas after transplantation into immunodeficient mice. The human adult germline stem cells differentiated into various types of somatic cells of all three germ layers when grown under conditions used to induce the differentiation of human embryonic stem cells. We conclude that the generation of human adult germline stem cells from testicular biopsies may provide simple and non-controversial access to individual cell-based therapy without the ethical and immunological problems associated with human embryonic stem cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Conrad, Sabine -- Renninger, Markus -- Hennenlotter, Jorg -- Wiesner, Tina -- Just, Lothar -- Bonin, Michael -- Aicher, Wilhelm -- Buhring, Hans-Jorg -- Mattheus, Ulrich -- Mack, Andreas -- Wagner, Hans-Joachim -- Minger, Stephen -- Matzkies, Matthias -- Reppel, Michael -- Hescheler, Jurgen -- Sievert, Karl-Dietrich -- Stenzl, Arnulf -- Skutella, Thomas -- England -- Nature. 2008 Nov 20;456(7220):344-9. doi: 10.1038/nature07404.

    Description: Dorsal-ventral patterning in vertebrate and invertebrate embryos is mediated by a conserved system of secreted proteins that establishes a bone morphogenetic protein (BMP) gradient. Although the Drosophila embryonic Decapentaplegic (Dpp) gradient has served as a model to understand how morphogen gradients are established, no role for the extracellular matrix has been previously described. Here we show that type IV collagen extracellular matrix proteins bind Dpp and regulate its signalling in both the Drosophila embryo and ovary. We provide evidence that the interaction between Dpp and type IV collagen augments Dpp signalling in the embryo by promoting gradient formation, yet it restricts the signalling range in the ovary through sequestration of the Dpp ligand. Together, these results identify a critical function of type IV collagens in modulating Dpp in the extracellular space during Drosophila development. On the basis of our findings that human type IV collagen binds BMP4, we predict that this role of type IV collagens will be conserved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Xiaomeng -- Harris, Robin E -- Bayston, Laura J -- Ashe, Hilary L -- BBS/B/11672/Biotechnology and Biological Sciences Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- England -- Nature. 2008 Sep 4;455(7209):72-7. doi: 10.1038/nature07214.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Faculty of Life Sciences, The University of Manchester, Oxford Road, Manchester M13 9PT, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18701888" target="_blank"〉PubMed〈/a〉

    Description: The existence of a small population of 'cancer-initiating cells' responsible for tumour maintenance has been firmly demonstrated in leukaemia. This concept is currently being tested in solid tumours. Leukaemia-initiating cells, particularly those that are in a quiescent state, are thought to be resistant to chemotherapy and targeted therapies, resulting in disease relapse. Chronic myeloid leukaemia is a paradigmatic haematopoietic stem cell disease in which the leukaemia-initiating-cell pool is not eradicated by current therapy, leading to disease relapse on drug discontinuation. Here we define the critical role of the promyelocytic leukaemia protein (PML) tumour suppressor in haematopoietic stem cell maintenance, and present a new therapeutic approach for targeting quiescent leukaemia-initiating cells and possibly cancer-initiating cells by pharmacological inhibition of PML.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2712082/" 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/PMC2712082/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ito, Keisuke -- Bernardi, Rosa -- Morotti, Alessandro -- Matsuoka, Sahoko -- Saglio, Giuseppe -- Ikeda, Yasuo -- Rosenblatt, Jacalyn -- Avigan, David E -- Teruya-Feldstein, Julie -- Pandolfi, Pier Paolo -- K99 CA139009/CA/NCI NIH HHS/ -- R00 CA139009/CA/NCI NIH HHS/ -- R37 CA071692/CA/NCI NIH HHS/ -- R37 CA071692-12/CA/NCI NIH HHS/ -- England -- Nature. 2008 Jun 19;453(7198):1072-8. doi: 10.1038/nature07016.

    Description: Our decisions are guided by information learnt from our environment. This information may come via personal experiences of reward, but also from the behaviour of social partners. Social learning is widely held to be distinct from other forms of learning in its mechanism and neural implementation; it is often assumed to compete with simpler mechanisms, such as reward-based associative learning, to drive behaviour. Recently, neural signals have been observed during social exchange reminiscent of signals seen in studies of associative learning. Here we demonstrate that social information may be acquired using the same associative processes assumed to underlie reward-based learning. We find that key computational variables for learning in the social and reward domains are processed in a similar fashion, but in parallel neural processing streams. Two neighbouring divisions of the anterior cingulate cortex were central to learning about social and reward-based information, and for determining the extent to which each source of information guides behaviour. When making a decision, however, the information learnt using these parallel streams was combined within ventromedial prefrontal cortex. These findings suggest that human social valuation can be realized by means of the same associative processes previously established for learning other, simpler, features of the environment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2605577/" 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/PMC2605577/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Behrens, Timothy E J -- Hunt, Laurence T -- Woolrich, Mark W -- Rushworth, Matthew F S -- G0501316/Medical Research Council/United Kingdom -- G0501316(75487)/Medical Research Council/United Kingdom -- G0600994/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 Nov 13;456(7219):245-9. doi: 10.1038/nature07538.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉FMRIB Centre, University of Oxford, John Radcliffe Hospital, Oxford OX3 9DU, UK. behrens@fmrib.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19005555" target="_blank"〉PubMed〈/a〉

    Description: The integrity of the cornea, the most anterior part of the eye, is indispensable for vision. Forty-five million individuals worldwide are bilaterally blind and another 135 million have severely impaired vision in both eyes because of loss of corneal transparency; treatments range from local medications to corneal transplants, and more recently to stem cell therapy. The corneal epithelium is a squamous epithelium that is constantly renewing, with a vertical turnover of 7 to 14 days in many mammals. Identification of slow cycling cells (label-retaining cells) in the limbus of the mouse has led to the notion that the limbus is the niche for the stem cells responsible for the long-term renewal of the cornea; hence, the corneal epithelium is supposedly renewed by cells generated at and migrating from the limbus, in marked opposition to other squamous epithelia in which each resident stem cell has in charge a limited area of epithelium. Here we show that the corneal epithelium of the mouse can be serially transplanted, is self-maintained and contains oligopotent stem cells with the capacity to generate goblet cells if provided with a conjunctival environment. Furthermore, the entire ocular surface of the pig, including the cornea, contains oligopotent stem cells (holoclones) with the capacity to generate individual colonies of corneal and conjunctival cells. Therefore, the limbus is not the only niche for corneal stem cells and corneal renewal is not different from other squamous epithelia. We propose a model that unifies our observations with the literature and explains why the limbal region is enriched in stem cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Majo, Francois -- Rochat, Ariane -- Nicolas, Michael -- Jaoude, Georges Abou -- Barrandon, Yann -- England -- Nature. 2008 Nov 13;456(7219):250-4. doi: 10.1038/nature07406.

    Description: Understanding the mechanisms that determine an individual's sex remains a primary challenge for evolutionary biology. Chromosome-based systems (genotypic sex determination) that generate roughly equal numbers of sons and daughters accord with theory, but the adaptive significance of environmental sex determination (that is, when embryonic environmental conditions determine offspring sex, ESD) is a major unsolved problem. Theoretical models predict that selection should favour ESD over genotypic sex determination when the developmental environment differentially influences male versus female fitness (that is, the Charnov-Bull model), but empirical evidence for this hypothesis remains elusive in amniote vertebrates--the clade in which ESD is most prevalent. Here we provide the first substantial empirical support for this model by showing that incubation temperatures influence reproductive success of males differently than that of females in a short-lived lizard (Amphibolurus muricatus, Agamidae) with temperature-dependent sex determination. We incubated eggs at a variety of temperatures, and de-confounded sex and incubation temperature by using hormonal manipulations to embryos. We then raised lizards in field enclosures and quantified their lifetime reproductive success. Incubation temperature affected reproductive success differently in males versus females in exactly the way predicted by theory: the fitness of each sex was maximized by the incubation temperature that produces that sex. Our results provide unequivocal empirical support for the Charnov-Bull model for the adaptive significance of temperature-dependent sex determination in amniote vertebrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warner, D A -- Shine, R -- England -- Nature. 2008 Jan 31;451(7178):566-8. doi: 10.1038/nature06519.

    Description: Internal brain states form key determinants for sensory perception, sensorimotor coordination and learning. A prominent reflection of different brain states in the mammalian central nervous system is the presence of distinct patterns of cortical synchrony, as revealed by extracellular recordings of the electroencephalogram, local field potential and action potentials. Such temporal correlations of cortical activity are thought to be fundamental mechanisms of neuronal computation. However, it is unknown how cortical synchrony is reflected in the intracellular membrane potential (V(m)) dynamics of behaving animals. Here we show, using dual whole-cell recordings from layer 2/3 primary somatosensory barrel cortex in behaving mice, that the V(m) of nearby neurons is highly correlated during quiet wakefulness. However, when the mouse is whisking, an internally generated state change reduces the V(m) correlation, resulting in a desynchronized local field potential and electroencephalogram. Action potential activity was sparse during both quiet wakefulness and active whisking. Single action potentials were driven by a large, brief and specific excitatory input that was not present in the V(m) of neighbouring cells. Action potential initiation occurs with a higher signal-to-noise ratio during active whisking than during quiet periods. Therefore, we show that an internal brain state dynamically regulates cortical membrane potential synchrony during behaviour and defines different modes of cortical processing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Poulet, James F A -- Petersen, Carl C H -- England -- Nature. 2008 Aug 14;454(7206):881-5. doi: 10.1038/nature07150.

    Description: We present a draft genome sequence of the platypus, Ornithorhynchus anatinus. This monotreme exhibits a fascinating combination of reptilian and mammalian characters. For example, platypuses have a coat of fur adapted to an aquatic lifestyle; platypus females lactate, yet lay eggs; and males are equipped with venom similar to that of reptiles. Analysis of the first monotreme genome aligned these features with genetic innovations. We find that reptile and platypus venom proteins have been co-opted independently from the same gene families; milk protein genes are conserved despite platypuses laying eggs; and immune gene family expansions are directly related to platypus biology. Expansions of protein, non-protein-coding RNA and microRNA families, as well as repeat elements, are identified. Sequencing of this genome now provides a valuable resource for deep mammalian comparative analyses, as well as for monotreme biology and conservation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2803040/" 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/PMC2803040/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Wesley C -- Hillier, LaDeana W -- Marshall Graves, Jennifer A -- Birney, Ewan -- Ponting, Chris P -- Grutzner, Frank -- Belov, Katherine -- Miller, Webb -- Clarke, Laura -- Chinwalla, Asif T -- Yang, Shiaw-Pyng -- Heger, Andreas -- Locke, Devin P -- Miethke, Pat -- Waters, Paul D -- Veyrunes, Frederic -- Fulton, Lucinda -- Fulton, Bob -- Graves, Tina -- Wallis, John -- Puente, Xose S -- Lopez-Otin, Carlos -- Ordonez, Gonzalo R -- Eichler, Evan E -- Chen, Lin -- Cheng, Ze -- Deakin, Janine E -- Alsop, Amber -- Thompson, Katherine -- Kirby, Patrick -- Papenfuss, Anthony T -- Wakefield, Matthew J -- Olender, Tsviya -- Lancet, Doron -- Huttley, Gavin A -- Smit, Arian F A -- Pask, Andrew -- Temple-Smith, Peter -- Batzer, Mark A -- Walker, Jerilyn A -- Konkel, Miriam K -- Harris, Robert S -- Whittington, Camilla M -- Wong, Emily S W -- Gemmell, Neil J -- Buschiazzo, Emmanuel -- Vargas Jentzsch, Iris M -- Merkel, Angelika -- Schmitz, Juergen -- Zemann, Anja -- Churakov, Gennady -- Kriegs, Jan Ole -- Brosius, Juergen -- Murchison, Elizabeth P -- Sachidanandam, Ravi -- Smith, Carly -- Hannon, Gregory J -- Tsend-Ayush, Enkhjargal -- McMillan, Daniel -- Attenborough, Rosalind -- Rens, Willem -- Ferguson-Smith, Malcolm -- Lefevre, Christophe M -- Sharp, Julie A -- Nicholas, Kevin R -- Ray, David A -- Kube, Michael -- Reinhardt, Richard -- Pringle, Thomas H -- Taylor, James -- Jones, Russell C -- Nixon, Brett -- Dacheux, Jean-Louis -- Niwa, Hitoshi -- Sekita, Yoko -- Huang, Xiaoqiu -- Stark, Alexander -- Kheradpour, Pouya -- Kellis, Manolis -- Flicek, Paul -- Chen, Yuan -- Webber, Caleb -- Hardison, Ross -- Nelson, Joanne -- Hallsworth-Pepin, Kym -- Delehaunty, Kim -- Markovic, Chris -- Minx, Pat -- Feng, Yucheng -- Kremitzki, Colin -- Mitreva, Makedonka -- Glasscock, Jarret -- Wylie, Todd -- Wohldmann, Patricia -- Thiru, Prathapan -- Nhan, Michael N -- Pohl, Craig S -- Smith, Scott M -- Hou, Shunfeng -- Nefedov, Mikhail -- de Jong, Pieter J -- Renfree, Marilyn B -- Mardis, Elaine R -- Wilson, Richard K -- 062023/Wellcome Trust/United Kingdom -- HG002238/HG/NHGRI NIH HHS/ -- MC_U137761446/Medical Research Council/United Kingdom -- P01 CA013106/CA/NCI NIH HHS/ -- P01 CA013106-37/CA/NCI NIH HHS/ -- R01 GM59290/GM/NIGMS NIH HHS/ -- R01 HG002939/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG004037-02/HG/NHGRI NIH HHS/ -- R01HG02385/HG/NHGRI NIH HHS/ -- Medical Research Council/United Kingdom -- England -- Nature. 2008 May 8;453(7192):175-83. doi: 10.1038/nature06936.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genome Sequencing Center, Washington University School of Medicine, Campus Box 8501, 4444 Forest Park Avenue, St Louis, Missouri 63108, USA. wwarren@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18464734" target="_blank"〉PubMed〈/a〉

    Description: Brain mechanisms for communication must establish a correspondence between sensory and motor codes used to represent the signal. One idea is that this correspondence is established at the level of single neurons that are active when the individual performs a particular gesture or observes a similar gesture performed by another individual. Although neurons that display a precise auditory-vocal correspondence could facilitate vocal communication, they have yet to be identified. Here we report that a certain class of neurons in the swamp sparrow forebrain displays a precise auditory-vocal correspondence. We show that these neurons respond in a temporally precise fashion to auditory presentation of certain note sequences in this songbird's repertoire and to similar note sequences in other birds' songs. These neurons display nearly identical patterns of activity when the bird sings the same sequence, and disrupting auditory feedback does not alter this singing-related activity, indicating it is motor in nature. Furthermore, these neurons innervate striatal structures important for song learning, raising the possibility that singing-related activity in these cells is compared to auditory feedback to guide vocal learning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prather, J F -- Peters, S -- Nowicki, S -- Mooney, R -- R01 DC002524/DC/NIDCD NIH HHS/ -- England -- Nature. 2008 Jan 17;451(7176):305-10. doi: 10.1038/nature06492.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Duke University Medical Center, North Carolina 27710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18202651" target="_blank"〉PubMed〈/a〉

    Description: DNA sequence information underpins genetic research, enabling discoveries of important biological or medical benefit. Sequencing projects have traditionally used long (400-800 base pair) reads, but the existence of reference sequences for the human and many other genomes makes it possible to develop new, fast approaches to re-sequencing, whereby shorter reads are compared to a reference to identify intraspecies genetic variation. Here we report an approach that generates several billion bases of accurate nucleotide sequence per experiment at low cost. Single molecules of DNA are attached to a flat surface, amplified in situ and used as templates for synthetic sequencing with fluorescent reversible terminator deoxyribonucleotides. Images of the surface are analysed to generate high-quality sequence. We demonstrate application of this approach to human genome sequencing on flow-sorted X chromosomes and then scale the approach to determine the genome sequence of a male Yoruba from Ibadan, Nigeria. We build an accurate consensus sequence from 〉30x average depth of paired 35-base reads. We characterize four million single-nucleotide polymorphisms and four hundred thousand structural variants, many of which were previously unknown. Our approach is effective for accurate, rapid and economical whole-genome re-sequencing and many other biomedical applications.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2581791/" 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/PMC2581791/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bentley, David R -- Balasubramanian, Shankar -- Swerdlow, Harold P -- Smith, Geoffrey P -- Milton, John -- Brown, Clive G -- Hall, Kevin P -- Evers, Dirk J -- Barnes, Colin L -- Bignell, Helen R -- Boutell, Jonathan M -- Bryant, Jason -- Carter, Richard J -- Keira Cheetham, R -- Cox, Anthony J -- Ellis, Darren J -- Flatbush, Michael R -- Gormley, Niall A -- Humphray, Sean J -- Irving, Leslie J -- Karbelashvili, Mirian S -- Kirk, Scott M -- Li, Heng -- Liu, Xiaohai -- Maisinger, Klaus S -- Murray, Lisa J -- Obradovic, Bojan -- Ost, Tobias -- Parkinson, Michael L -- Pratt, Mark R -- Rasolonjatovo, Isabelle M J -- Reed, Mark T -- Rigatti, Roberto -- Rodighiero, Chiara -- Ross, Mark T -- Sabot, Andrea -- Sankar, Subramanian V -- Scally, Aylwyn -- Schroth, Gary P -- Smith, Mark E -- Smith, Vincent P -- Spiridou, Anastassia -- Torrance, Peta E -- Tzonev, Svilen S -- Vermaas, Eric H -- Walter, Klaudia -- Wu, Xiaolin -- Zhang, Lu -- Alam, Mohammed D -- Anastasi, Carole -- Aniebo, Ify C -- Bailey, David M D -- Bancarz, Iain R -- Banerjee, Saibal -- Barbour, Selena G -- Baybayan, Primo A -- Benoit, Vincent A -- Benson, Kevin F -- Bevis, Claire -- Black, Phillip J -- Boodhun, Asha -- Brennan, Joe S -- Bridgham, John A -- Brown, Rob C -- Brown, Andrew A -- Buermann, Dale H -- Bundu, Abass A -- Burrows, James C -- Carter, Nigel P -- Castillo, Nestor -- Chiara E Catenazzi, Maria -- Chang, Simon -- Neil Cooley, R -- Crake, Natasha R -- Dada, Olubunmi O -- Diakoumakos, Konstantinos D -- Dominguez-Fernandez, Belen -- Earnshaw, David J -- Egbujor, Ugonna C -- Elmore, David W -- Etchin, Sergey S -- Ewan, Mark R -- Fedurco, Milan -- Fraser, Louise J -- Fuentes Fajardo, Karin V -- Scott Furey, W -- George, David -- Gietzen, Kimberley J -- Goddard, Colin P -- Golda, George S -- Granieri, Philip A -- Green, David E -- Gustafson, David L -- Hansen, Nancy F -- Harnish, Kevin -- Haudenschild, Christian D -- Heyer, Narinder I -- Hims, Matthew M -- Ho, Johnny T -- Horgan, Adrian M -- Hoschler, Katya -- Hurwitz, Steve -- Ivanov, Denis V -- Johnson, Maria Q -- James, Terena -- Huw Jones, T A -- Kang, Gyoung-Dong -- Kerelska, Tzvetana H -- Kersey, Alan D -- Khrebtukova, Irina -- Kindwall, Alex P -- Kingsbury, Zoya -- Kokko-Gonzales, Paula I -- Kumar, Anil -- Laurent, Marc A -- Lawley, Cynthia T -- Lee, Sarah E -- Lee, Xavier -- Liao, Arnold K -- Loch, Jennifer A -- Lok, Mitch -- Luo, Shujun -- Mammen, Radhika M -- Martin, John W -- McCauley, Patrick G -- McNitt, Paul -- Mehta, Parul -- Moon, Keith W -- Mullens, Joe W -- Newington, Taksina -- Ning, Zemin -- Ling Ng, Bee -- Novo, Sonia M -- O'Neill, Michael J -- Osborne, Mark A -- Osnowski, Andrew -- Ostadan, Omead -- Paraschos, Lambros L -- Pickering, Lea -- Pike, Andrew C -- Pike, Alger C -- Chris Pinkard, D -- Pliskin, Daniel P -- Podhasky, Joe -- Quijano, Victor J -- Raczy, Come -- Rae, Vicki H -- Rawlings, Stephen R -- Chiva Rodriguez, Ana -- Roe, Phyllida M -- Rogers, John -- Rogert Bacigalupo, Maria C -- Romanov, Nikolai -- Romieu, Anthony -- Roth, Rithy K -- Rourke, Natalie J -- Ruediger, Silke T -- Rusman, Eli -- Sanches-Kuiper, Raquel M -- Schenker, Martin R -- Seoane, Josefina M -- Shaw, Richard J -- Shiver, Mitch K -- Short, Steven W -- Sizto, Ning L -- Sluis, Johannes P -- Smith, Melanie A -- Ernest Sohna Sohna, Jean -- Spence, Eric J -- Stevens, Kim -- Sutton, Neil -- Szajkowski, Lukasz -- Tregidgo, Carolyn L -- Turcatti, Gerardo -- Vandevondele, Stephanie -- Verhovsky, Yuli -- Virk, Selene M -- Wakelin, Suzanne -- Walcott, Gregory C -- Wang, Jingwen -- Worsley, Graham J -- Yan, Juying -- Yau, Ling -- Zuerlein, Mike -- Rogers, Jane -- Mullikin, James C -- Hurles, Matthew E -- McCooke, Nick J -- West, John S -- Oaks, Frank L -- Lundberg, Peter L -- Klenerman, David -- Durbin, Richard -- Smith, Anthony J -- B05823/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0701805/Medical Research Council/United Kingdom -- MOL04534/Biotechnology and Biological Sciences Research Council/United Kingdom -- Z01 HG200330-03/Intramural NIH HHS/ -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 Nov 6;456(7218):53-9. doi: 10.1038/nature07517.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Illumina Cambridge Ltd.

    Description: Nuclear exclusion of the PTEN (phosphatase and tensin homologue deleted in chromosome 10) tumour suppressor has been associated with cancer progression. However, the mechanisms leading to this aberrant PTEN localization in human cancers are currently unknown. We have previously reported that ubiquitinylation of PTEN at specific lysine residues regulates its nuclear-cytoplasmic partitioning. Here we show that functional promyelocytic leukaemia protein (PML) nuclear bodies co-ordinate PTEN localization by opposing the action of a previously unknown PTEN-deubiquitinylating enzyme, herpesvirus-associated ubiquitin-specific protease (HAUSP, also known as USP7), and that the integrity of this molecular framework is required for PTEN to be able to enter the nucleus. We find that PTEN is aberrantly localized in acute promyelocytic leukaemia, in which PML function is disrupted by the PML-RARalpha fusion oncoprotein. Remarkably, treatment with drugs that trigger PML-RARalpha degradation, such as all-trans retinoic acid or arsenic trioxide, restore nuclear PTEN. We demonstrate that PML opposes the activity of HAUSP towards PTEN through a mechanism involving the adaptor protein DAXX (death domain-associated protein). In support of this paradigm, we show that HAUSP is overexpressed in human prostate cancer and is associated with PTEN nuclear exclusion. Thus, our results delineate a previously unknown PML-DAXX-HAUSP molecular network controlling PTEN deubiquitinylation and trafficking, which is perturbed by oncogenic cues in human cancer, in turn defining a new deubiquitinylation-dependent model for PTEN subcellular compartmentalization.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3398484/" 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/PMC3398484/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Song, Min Sup -- Salmena, Leonardo -- Carracedo, Arkaitz -- Egia, Ainara -- Lo-Coco, Francesco -- Teruya-Feldstein, Julie -- Pandolfi, Pier Paolo -- P50 CA092629/CA/NCI NIH HHS/ -- P50 CA092629-01/CA/NCI NIH HHS/ -- R01 CA082328/CA/NCI NIH HHS/ -- England -- Nature. 2008 Oct 9;455(7214):813-7. doi: 10.1038/nature07290.

    Description: On activation by receptors, the ubiquitously expressed class IA isoforms (p110alpha and p110beta) of phosphatidylinositol-3-OH kinase (PI(3)K) generate lipid second messengers, which initiate multiple signal transduction cascades. Recent studies have demonstrated specific functions for p110alpha in growth factor and insulin signalling. To probe for distinct functions of p110beta, we constructed conditional knockout mice. Here we show that ablation of p110beta in the livers of the resulting mice leads to impaired insulin sensitivity and glucose homeostasis, while having little effect on phosphorylation of Akt, suggesting the involvement of a kinase-independent role of p110beta in insulin metabolic action. Using established mouse embryonic fibroblasts, we found that removal of p110beta also had little effect on Akt phosphorylation in response to stimulation by insulin and epidermal growth factor, but resulted in retarded cell proliferation. Reconstitution of p110beta-null cells with a wild-type or kinase-dead allele of p110beta demonstrated that p110beta possesses kinase-independent functions in regulating cell proliferation and trafficking. However, the kinase activity of p110beta was required for G-protein-coupled receptor signalling triggered by lysophosphatidic acid and had a function in oncogenic transformation. Most strikingly, in an animal model of prostate tumour formation induced by Pten loss, ablation of p110beta (also known as Pik3cb), but not that of p110alpha (also known as Pik3ca), impeded tumorigenesis with a concomitant diminution of Akt phosphorylation. Taken together, our findings demonstrate both kinase-dependent and kinase-independent functions for p110beta, and strongly indicate the kinase-dependent functions of p110beta as a promising target in cancer therapy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2750091/" 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/PMC2750091/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jia, Shidong -- Liu, Zhenning -- Zhang, Sen -- Liu, Pixu -- Zhang, Lei -- Lee, Sang Hyun -- Zhang, Jing -- Signoretti, Sabina -- Loda, Massimo -- Roberts, Thomas M -- Zhao, Jean J -- P01 CA050661/CA/NCI NIH HHS/ -- P01 CA050661-200001/CA/NCI NIH HHS/ -- P01 CA089021/CA/NCI NIH HHS/ -- P01 CA089021-06A1/CA/NCI NIH HHS/ -- P50 CA089393/CA/NCI NIH HHS/ -- P50 CA089393-08S1/CA/NCI NIH HHS/ -- P50 CA090381/CA/NCI NIH HHS/ -- P50 CA090381-05/CA/NCI NIH HHS/ -- R01 CA030002/CA/NCI NIH HHS/ -- R01 CA030002-27/CA/NCI NIH HHS/ -- R01 CA134502/CA/NCI NIH HHS/ -- R01 CA134502-01/CA/NCI NIH HHS/ -- England -- Nature. 2008 Aug 7;454(7205):776-9. doi: 10.1038/nature07091.

    Description: Myc is a pleiotropic basic helix-loop-helix leucine zipper transcription factor that coordinates expression of the diverse intracellular and extracellular programs that together are necessary for growth and expansion of somatic cells. In principle, this makes inhibition of Myc an attractive pharmacological approach for treating diverse types of cancer. However, enthusiasm has been muted by lack of direct evidence that Myc inhibition would be therapeutically efficacious, concerns that it would induce serious side effects by inhibiting proliferation of normal tissues, and practical difficulties in designing Myc inhibitory drugs. We have modelled genetically both the therapeutic impact and the side effects of systemic Myc inhibition in a preclinical mouse model of Ras-induced lung adenocarcinoma by reversible, systemic expression of a dominant-interfering Myc mutant. We show that Myc inhibition triggers rapid regression of incipient and established lung tumours, defining an unexpected role for endogenous Myc function in the maintenance of Ras-dependent tumours in vivo. Systemic Myc inhibition also exerts profound effects on normal regenerating tissues. However, these effects are well tolerated over extended periods and rapidly and completely reversible. Our data demonstrate the feasibility of targeting Myc, a common downstream conduit for many oncogenic signals, as an effective, efficient and tumour-specific cancer therapy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4485609/" 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/PMC4485609/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Soucek, Laura -- Whitfield, Jonathan -- Martins, Carla P -- Finch, Andrew J -- Murphy, Daniel J -- Sodir, Nicole M -- Karnezis, Anthony N -- Swigart, Lamorna Brown -- Nasi, Sergio -- Evan, Gerard I -- 2R01 CA98018/CA/NCI NIH HHS/ -- R01 CA098018/CA/NCI NIH HHS/ -- R01 CA098018-05/CA/NCI NIH HHS/ -- R01 CA098018-06/CA/NCI NIH HHS/ -- R01 CA098018-07/CA/NCI NIH HHS/ -- T32 CA108462/CA/NCI NIH HHS/ -- T32 CA108462-01/CA/NCI NIH HHS/ -- England -- Nature. 2008 Oct 2;455(7213):679-83. doi: 10.1038/nature07260.

    Description: Half a century ago, the apical ectodermal ridge (AER) at the distal tip of the tetrapod limb bud was shown to produce signals necessary for development along the proximal-distal (P-D) axis, but how these signals influence limb patterning is still much debated. Fibroblast growth factor (FGF) gene family members are key AER-derived signals, with Fgf4, Fgf8, Fgf9 and Fgf17 expressed specifically in the mouse AER. Here we demonstrate that mouse limbs lacking Fgf4, Fgf9 and Fgf17 have normal skeletal pattern, indicating that Fgf8 is sufficient among AER-FGFs to sustain normal limb formation. Inactivation of Fgf8 alone causes a mild skeletal phenotype; however, when we also removed different combinations of the other AER-FGF genes, we obtained unexpected skeletal phenotypes of increasing severity, reflecting the contribution that each FGF can make to the total AER-FGF signal. Analysis of the compound mutant limb buds revealed that, in addition to sustaining cell survival, AER-FGFs regulate P-D-patterning gene expression during early limb bud development, providing genetic evidence that AER-FGFs function to specify a distal domain and challenging the long-standing hypothesis that AER-FGF signalling is permissive rather than instructive for limb patterning. We discuss how a two-signal model for P-D patterning can be integrated with the concept of early specification to explain the genetic data presented here.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2631409/" 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/PMC2631409/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mariani, Francesca V -- Ahn, Christina P -- Martin, Gail R -- F32 HD008696/HD/NICHD NIH HHS/ -- F32 HD008696-01/HD/NICHD NIH HHS/ -- F32 HD008696-02/HD/NICHD NIH HHS/ -- F32 HD008696-03/HD/NICHD NIH HHS/ -- R01 HD034380/HD/NICHD NIH HHS/ -- R01 HD034380-05/HD/NICHD NIH HHS/ -- R01 HD034380-06/HD/NICHD NIH HHS/ -- R01 HD034380-07/HD/NICHD NIH HHS/ -- R01 HD034380-08/HD/NICHD NIH HHS/ -- R01 HD034380-09/HD/NICHD NIH HHS/ -- R01 HD34380/HD/NICHD NIH HHS/ -- England -- Nature. 2008 May 15;453(7193):401-5. doi: 10.1038/nature06876.

    Description: Type 1 diabetes (T1D) is a debilitating autoimmune disease that results from T-cell-mediated destruction of insulin-producing beta-cells. Its incidence has increased during the past several decades in developed countries, suggesting that changes in the environment (including the human microbial environment) may influence disease pathogenesis. The incidence of spontaneous T1D in non-obese diabetic (NOD) mice can be affected by the microbial environment in the animal housing facility or by exposure to microbial stimuli, such as injection with mycobacteria or various microbial products. Here we show that specific pathogen-free NOD mice lacking MyD88 protein (an adaptor for multiple innate immune receptors that recognize microbial stimuli) do not develop T1D. The effect is dependent on commensal microbes because germ-free MyD88-negative NOD mice develop robust diabetes, whereas colonization of these germ-free MyD88-negative NOD mice with a defined microbial consortium (representing bacterial phyla normally present in human gut) attenuates T1D. We also find that MyD88 deficiency changes the composition of the distal gut microbiota, and that exposure to the microbiota of specific pathogen-free MyD88-negative NOD donors attenuates T1D in germ-free NOD recipients. Together, these findings indicate that interaction of the intestinal microbes with the innate immune system is a critical epigenetic factor modifying T1D predisposition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2574766/" 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/PMC2574766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wen, Li -- Ley, Ruth E -- Volchkov, Pavel Yu -- Stranges, Peter B -- Avanesyan, Lia -- Stonebraker, Austin C -- Hu, Changyun -- Wong, F Susan -- Szot, Gregory L -- Bluestone, Jeffrey A -- Gordon, Jeffrey I -- Chervonsky, Alexander V -- DK063452/DK/NIDDK NIH HHS/ -- DK30292/DK/NIDDK NIH HHS/ -- DK42086/DK/NIDDK NIH HHS/ -- DK45735/DK/NIDDK NIH HHS/ -- DK70977/DK/NIDDK NIH HHS/ -- P30 DK042086/DK/NIDDK NIH HHS/ -- P30 DK042086-16/DK/NIDDK NIH HHS/ -- P30 DK045735/DK/NIDDK NIH HHS/ -- P30 DK045735-10/DK/NIDDK NIH HHS/ -- P30 DK045735-119006/DK/NIDDK NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- P30 DK056341-07/DK/NIDDK NIH HHS/ -- P30 DK056341-08/DK/NIDDK NIH HHS/ -- P30 DK063720/DK/NIDDK NIH HHS/ -- P30 DK063720-01/DK/NIDDK NIH HHS/ -- P30 DK63720/DK/NIDDK NIH HHS/ -- R01 DK030292/DK/NIDDK NIH HHS/ -- R01 DK030292-24/DK/NIDDK NIH HHS/ -- R01 DK070977/DK/NIDDK NIH HHS/ -- R01 DK070977-04/DK/NIDDK NIH HHS/ -- R21 DK063452/DK/NIDDK NIH HHS/ -- R21 DK063452-02/DK/NIDDK NIH HHS/ -- R37 AI046643/AI/NIAID NIH HHS/ -- R37 AI046643-10/AI/NIAID NIH HHS/ -- R37 AI46643/AI/NIAID NIH HHS/ -- England -- Nature. 2008 Oct 23;455(7216):1109-13. doi: 10.1038/nature07336.

    Description: Human cancer cells typically harbour multiple chromosomal aberrations, nucleotide substitutions and epigenetic modifications that drive malignant transformation. The Cancer Genome Atlas (TCGA) pilot project aims to assess the value of large-scale multi-dimensional analysis of these molecular characteristics in human cancer and to provide the data rapidly to the research community. Here we report the interim integrative analysis of DNA copy number, gene expression and DNA methylation aberrations in 206 glioblastomas--the most common type of adult brain cancer--and nucleotide sequence aberrations in 91 of the 206 glioblastomas. This analysis provides new insights into the roles of ERBB2, NF1 and TP53, uncovers frequent mutations of the phosphatidylinositol-3-OH kinase regulatory subunit gene PIK3R1, and provides a network view of the pathways altered in the development of glioblastoma. Furthermore, integration of mutation, DNA methylation and clinical treatment data reveals a link between MGMT promoter methylation and a hypermutator phenotype consequent to mismatch repair deficiency in treated glioblastomas, an observation with potential clinical implications. Together, these findings establish the feasibility and power of TCGA, demonstrating that it can rapidly expand knowledge of the molecular basis of cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2671642/" 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/PMC2671642/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cancer Genome Atlas Research Network -- R01 CA099041/CA/NCI NIH HHS/ -- R01 CA099041-05/CA/NCI NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- U24 CA126543-01/CA/NCI NIH HHS/ -- U24 CA126544/CA/NCI NIH HHS/ -- U24 CA126544-01/CA/NCI NIH HHS/ -- U24 CA126546/CA/NCI NIH HHS/ -- U24 CA126546-01/CA/NCI NIH HHS/ -- U24 CA126551-01/CA/NCI NIH HHS/ -- U24 CA126554/CA/NCI NIH HHS/ -- U24 CA126554-01/CA/NCI NIH HHS/ -- U24 CA126561/CA/NCI NIH HHS/ -- U24 CA126561-01/CA/NCI NIH HHS/ -- U24 CA126563/CA/NCI NIH HHS/ -- U24 CA126563-01/CA/NCI NIH HHS/ -- U24CA126543/CA/NCI NIH HHS/ -- U24CA126544/CA/NCI NIH HHS/ -- U24CA126546/CA/NCI NIH HHS/ -- U24CA126551/CA/NCI NIH HHS/ -- U24CA126554/CA/NCI NIH HHS/ -- U24CA126561/CA/NCI NIH HHS/ -- U24CA126563/CA/NCI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54 HG003067-01/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003079-05/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- U54 HG003273-01/HG/NHGRI NIH HHS/ -- U54HG003067/HG/NHGRI NIH HHS/ -- U54HG003079/HG/NHGRI NIH HHS/ -- U54HG003273/HG/NHGRI NIH HHS/ -- England -- Nature. 2008 Oct 23;455(7216):1061-8. doi: 10.1038/nature07385.

    Description: The association of genetic variation with disease and drug response, and improvements in nucleic acid technologies, have given great optimism for the impact of 'genomic medicine'. However, the formidable size of the diploid human genome, approximately 6 gigabases, has prevented the routine application of sequencing methods to deciphering complete individual human genomes. To realize the full potential of genomics for human health, this limitation must be overcome. Here we report the DNA sequence of a diploid genome of a single individual, James D. Watson, sequenced to 7.4-fold redundancy in two months using massively parallel sequencing in picolitre-size reaction vessels. This sequence was completed in two months at approximately one-hundredth of the cost of traditional capillary electrophoresis methods. Comparison of the sequence to the reference genome led to the identification of 3.3 million single nucleotide polymorphisms, of which 10,654 cause amino-acid substitution within the coding sequence. In addition, we accurately identified small-scale (2-40,000 base pair (bp)) insertion and deletion polymorphism as well as copy number variation resulting in the large-scale gain and loss of chromosomal segments ranging from 26,000 to 1.5 million base pairs. Overall, these results agree well with recent results of sequencing of a single individual by traditional methods. However, in addition to being faster and significantly less expensive, this sequencing technology avoids the arbitrary loss of genomic sequences inherent in random shotgun sequencing by bacterial cloning because it amplifies DNA in a cell-free system. As a result, we further demonstrate the acquisition of novel human sequence, including novel genes not previously identified by traditional genomic sequencing. This is the first genome sequenced by next-generation technologies. Therefore it is a pilot for the future challenges of 'personalized genome sequencing'.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wheeler, David A -- Srinivasan, Maithreyan -- Egholm, Michael -- Shen, Yufeng -- Chen, Lei -- McGuire, Amy -- He, Wen -- Chen, Yi-Ju -- Makhijani, Vinod -- Roth, G Thomas -- Gomes, Xavier -- Tartaro, Karrie -- Niazi, Faheem -- Turcotte, Cynthia L -- Irzyk, Gerard P -- Lupski, James R -- Chinault, Craig -- Song, Xing-zhi -- Liu, Yue -- Yuan, Ye -- Nazareth, Lynne -- Qin, Xiang -- Muzny, Donna M -- Margulies, Marcel -- Weinstock, George M -- Gibbs, Richard A -- Rothberg, Jonathan M -- U54 HG003273/HG/NHGRI NIH HHS/ -- England -- Nature. 2008 Apr 17;452(7189):872-6. doi: 10.1038/nature06884.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Genome Sequencing Center, Baylor College of Medicine, One Baylor Plaza, Houston, Texas 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18421352" target="_blank"〉PubMed〈/a〉

    Description: In many organisms, population-density sensing and sexual attraction rely on small-molecule-based signalling systems. In the nematode Caenorhabditis elegans, population density is monitored through specific glycosides of the dideoxysugar ascarylose (the 'ascarosides') that promote entry into an alternative larval stage, the non-feeding and highly persistent dauer stage. In addition, adult C. elegans males are attracted to hermaphrodites by a previously unidentified small-molecule signal. Here we show, by means of combinatorial activity-guided fractionation of the C. elegans metabolome, that the mating signal consists of a synergistic blend of three dauer-inducing ascarosides, which we call ascr#2, ascr#3 and ascr#4. This blend of ascarosides acts as a potent male attractant at very low concentrations, whereas at the higher concentrations required for dauer formation the compounds no longer attract males and instead deter hermaphrodites. The ascarosides ascr#2 and ascr#3 carry different, but overlapping, information, as ascr#3 is more potent as a male attractant than ascr#2, whereas ascr#2 is slightly more potent than ascr#3 in promoting dauer formation. We demonstrate that ascr#2, ascr#3 and ascr#4 are strongly synergistic, and that two types of neuron, the amphid single-ciliated sensory neuron type K (ASK) and the male-specific cephalic companion neuron (CEM), are required for male attraction by ascr#3. On the basis of these results, male attraction and dauer formation in C. elegans appear as alternative behavioural responses to a common set of signalling molecules. The ascaroside signalling system thus connects reproductive and developmental pathways and represents a unique example of structure- and concentration-dependent differential activity of signalling molecules.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2774729/" 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/PMC2774729/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Srinivasan, Jagan -- Kaplan, Fatma -- Ajredini, Ramadan -- Zachariah, Cherian -- Alborn, Hans T -- Teal, Peter E A -- Malik, Rabia U -- Edison, Arthur S -- Sternberg, Paul W -- Schroeder, Frank C -- P41 GM079571/GM/NIGMS NIH HHS/ -- P41 GM079571-02/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 Aug 28;454(7208):1115-8. doi: 10.1038/nature07168.

    Description: The kidney has an important role in the regulation of acid-base homeostasis. Renal ammonium production and excretion are essential for net acid excretion under basal conditions and during metabolic acidosis. Ammonium is secreted into the urine by the collecting duct, a distal nephron segment where ammonium transport is believed to occur by non-ionic NH(3) diffusion coupled to H(+) secretion. Here we show that this process is largely dependent on the Rhesus factor Rhcg. Mice lacking Rhcg have abnormal urinary acidification due to impaired ammonium excretion on acid loading-a feature of distal renal tubular acidosis. In vitro microperfused collecting ducts of Rhcg(-/-) acid-loaded mice show reduced apical permeability to NH(3) and impaired transepithelial NH(3) transport. Furthermore, Rhcg is localized in epididymal epithelial cells and is required for normal fertility and epididymal fluid pH. We anticipate a critical role for Rhcg in ammonium handling and pH homeostasis both in the kidney and the male reproductive tract.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biver, Sophie -- Belge, Hendrica -- Bourgeois, Soline -- Van Vooren, Pascale -- Nowik, Marta -- Scohy, Sophie -- Houillier, Pascal -- Szpirer, Josiane -- Szpirer, Claude -- Wagner, Carsten A -- Devuyst, Olivier -- Marini, Anna Maria -- England -- Nature. 2008 Nov 20;456(7220):339-43. doi: 10.1038/nature07518.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Universite Libre de Bruxelles (U.L.B.), Institut de Biologie et de Medecine Moleculaires, Laboratoire de Biologie du Developpement, Gosselies, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19020613" target="_blank"〉PubMed〈/a〉

    Description: Calcium signalling in astrocytes couples changes in neural activity to alterations in cerebral blood flow by eliciting vasoconstriction or vasodilation of arterioles. However, the mechanism for how these opposite astrocyte influences provide appropriate changes in vessel tone within an environment that has dynamic metabolic requirements remains unclear. Here we show that the ability of astrocytes to induce vasodilations over vasoconstrictions relies on the metabolic state of the rat brain tissue. When oxygen availability is lowered and astrocyte calcium concentration is elevated, astrocyte glycolysis and lactate release are maximized. External lactate attenuates transporter-mediated uptake from the extracellular space of prostaglandin E(2), leading to accumulation and subsequent vasodilation. In conditions of low oxygen concentration extracellular adenosine also increases, which blocks astrocyte-mediated constriction, facilitating dilation. These data reveal the role of metabolic substrates in regulating brain blood flow and provide a mechanism for differential astrocyte control over cerebrovascular diameter during different states of brain activation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4097022/" 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/PMC4097022/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gordon, Grant R J -- Choi, Hyun B -- Rungta, Ravi L -- Ellis-Davies, Graham C R -- MacVicar, Brian A -- R01 GM053395/GM/NIGMS NIH HHS/ -- R01 GM053395-13/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Dec 11;456(7223):745-9. doi: 10.1038/nature07525.

    Description: Despite intense investigation, mechanisms that facilitate the emergence of the pre-eclampsia phenotype in women are still unknown. Placental hypoxia, hypertension, proteinuria and oedema are the principal clinical features of this disease. It is speculated that hypoxia-driven disruption of the angiogenic balance involving vascular endothelial growth factor (VEGF)/placenta-derived growth factor (PLGF) and soluble Fms-like tyrosine kinase-1 (sFLT-1, the soluble form of VEGF receptor 1) might contribute to some of the maternal symptoms of pre-eclampsia. However, pre-eclampsia does not develop in all women with high sFLT-1 or low PLGF levels, and it also occurs in some women with low sFLT-1 and high PLGF levels. Moreover, recent experiments strongly suggest that several soluble factors affecting the vasculature are probably elevated because of placental hypoxia in the pre-eclamptic women, indicating that upstream molecular defect(s) may contribute to pre-eclampsia. Here we show that pregnant mice deficient in catechol-O-methyltransferase (COMT) show a pre-eclampsia-like phenotype resulting from an absence of 2-methoxyoestradiol (2-ME), a natural metabolite of oestradiol that is elevated during the third trimester of normal human pregnancy. 2-ME ameliorates all pre-eclampsia-like features without toxicity in the Comt(-/-) pregnant mice and suppresses placental hypoxia, hypoxia-inducible factor-1alpha expression and sFLT-1 elevation. The levels of COMT and 2-ME are significantly lower in women with severe pre-eclampsia. Our studies identify a genetic mouse model for pre-eclampsia and suggest that 2-ME may have utility as a plasma and urine diagnostic marker for this disease, and may also serve as a therapeutic supplement to prevent or treat this disorder.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kanasaki, Keizo -- Palmsten, Kristin -- Sugimoto, Hikaru -- Ahmad, Shakil -- Hamano, Yuki -- Xie, Liang -- Parry, Samuel -- Augustin, Hellmut G -- Gattone, Vincent H -- Folkman, Judah -- Strauss, Jerome F -- Kalluri, Raghu -- DK 13193/DK/NIDDK NIH HHS/ -- DK 55001/DK/NIDDK NIH HHS/ -- DK 61688/DK/NIDDK NIH HHS/ -- DK 62987/DK/NIDDK NIH HHS/ -- G0700288/Medical Research Council/United Kingdom -- R01 DK055001/DK/NIDDK NIH HHS/ -- R01 DK061688/DK/NIDDK NIH HHS/ -- British Heart Foundation/United Kingdom -- Medical Research Council/United Kingdom -- England -- Nature. 2008 Jun 19;453(7198):1117-21. doi: 10.1038/nature06951.

    Description: Dopamine orchestrates motor behaviour and reward-driven learning. Perturbations of dopamine signalling have been implicated in several neurological and psychiatric disorders, and in drug addiction. The actions of dopamine are mediated in part by the regulation of gene expression in the striatum, through mechanisms that are not fully understood. Here we show that drugs of abuse, as well as food reinforcement learning, promote the nuclear accumulation of 32-kDa dopamine-regulated and cyclic-AMP-regulated phosphoprotein (DARPP-32). This accumulation is mediated through a signalling cascade involving dopamine D1 receptors, cAMP-dependent activation of protein phosphatase-2A, dephosphorylation of DARPP-32 at Ser 97 and inhibition of its nuclear export. The nuclear accumulation of DARPP-32, a potent inhibitor of protein phosphatase-1, increases the phosphorylation of histone H3, an important component of nucleosomal response. Mutation of Ser 97 profoundly alters behavioural effects of drugs of abuse and decreases motivation for food, underlining the functional importance of this signalling cascade.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2796210/" 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/PMC2796210/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stipanovich, Alexandre -- Valjent, Emmanuel -- Matamales, Miriam -- Nishi, Akinori -- Ahn, Jung-Hyuck -- Maroteaux, Matthieu -- Bertran-Gonzalez, Jesus -- Brami-Cherrier, Karen -- Enslen, Herve -- Corbille, Anne-Gaelle -- Filhol, Odile -- Nairn, Angus C -- Greengard, Paul -- Herve, Denis -- Girault, Jean-Antoine -- DA10044/DA/NIDA NIH HHS/ -- MH74866/MH/NIMH NIH HHS/ -- P01 DA010044/DA/NIDA NIH HHS/ -- P01 DA010044-020002/DA/NIDA NIH HHS/ -- P01 DA010044-030002/DA/NIDA NIH HHS/ -- P01 DA010044-04/DA/NIDA NIH HHS/ -- P01 DA010044-040002/DA/NIDA NIH HHS/ -- P01 DA010044-05/DA/NIDA NIH HHS/ -- P01 DA010044-050002/DA/NIDA NIH HHS/ -- P01 DA010044-06/DA/NIDA NIH HHS/ -- P01 DA010044-060002/DA/NIDA NIH HHS/ -- P01 DA010044-07/DA/NIDA NIH HHS/ -- P01 DA010044-070002/DA/NIDA NIH HHS/ -- P01 DA010044-08/DA/NIDA NIH HHS/ -- P01 DA010044-080002/DA/NIDA NIH HHS/ -- P01 DA010044-09/DA/NIDA NIH HHS/ -- P01 DA010044-090002/DA/NIDA NIH HHS/ -- P01 DA010044-10/DA/NIDA NIH HHS/ -- P01 DA010044-100002/DA/NIDA NIH HHS/ -- P01 DA010044-11/DA/NIDA NIH HHS/ -- P01 DA010044-110005/DA/NIDA NIH HHS/ -- P01 DA010044-12/DA/NIDA NIH HHS/ -- P01 DA010044-120005/DA/NIDA NIH HHS/ -- P01 DA010044-129002/DA/NIDA NIH HHS/ -- P01 DA010044-13/DA/NIDA NIH HHS/ -- P01 DA010044-130005/DA/NIDA NIH HHS/ -- P01 DA010044-139002/DA/NIDA NIH HHS/ -- P01 DA010044-14/DA/NIDA NIH HHS/ -- P01 DA010044-140005/DA/NIDA NIH HHS/ -- P01 DA010044-149002/DA/NIDA NIH HHS/ -- P01 DA010044-14S1/DA/NIDA NIH HHS/ -- P50 MH074866/MH/NIMH NIH HHS/ -- P50 MH074866-010001/MH/NIMH NIH HHS/ -- P50 MH074866-019001/MH/NIMH NIH HHS/ -- P50 MH074866-020001/MH/NIMH NIH HHS/ -- P50 MH074866-029001/MH/NIMH NIH HHS/ -- P50 MH074866-030001/MH/NIMH NIH HHS/ -- P50 MH074866-039001/MH/NIMH NIH HHS/ -- P50 MH074866-040001/MH/NIMH NIH HHS/ -- P50 MH074866-049001/MH/NIMH NIH HHS/ -- P50 MH074866-050001/MH/NIMH NIH HHS/ -- P50 MH074866-059001/MH/NIMH NIH HHS/ -- England -- Nature. 2008 Jun 12;453(7197):879-84. doi: 10.1038/nature06994.

    Description: Angiogenesis and the development of a vascular network are required for tumour progression, and they involve the release of angiogenic factors, including vascular endothelial growth factor (VEGF-A), from both malignant and stromal cell types. Infiltration by cells of the myeloid lineage is a hallmark of many tumours, and in many cases the macrophages in these infiltrates express VEGF-A. Here we show that the deletion of inflammatory-cell-derived VEGF-A attenuates the formation of a typical high-density vessel network, thus blocking the angiogenic switch in solid tumours in mice. Vasculature in tumours lacking myeloid-cell-derived VEGF-A was less tortuous, with increased pericyte coverage and decreased vessel length, indicating vascular normalization. In addition, loss of myeloid-derived VEGF-A decreases the phosphorylation of VEGF receptor 2 (VEGFR2) in tumours, even though overall VEGF-A levels in the tumours are unaffected. However, deletion of myeloid-cell VEGF-A resulted in an accelerated tumour progression in multiple subcutaneous isograft models and an autochthonous transgenic model of mammary tumorigenesis, with less overall tumour cell death and decreased tumour hypoxia. Furthermore, loss of myeloid-cell VEGF-A increased the susceptibility of tumours to chemotherapeutic cytotoxicity. This shows that myeloid-derived VEGF-A is essential for the tumorigenic alteration of vasculature and signalling to VEGFR2, and that these changes act to retard, not promote, tumour progression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3103772/" 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/PMC3103772/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stockmann, Christian -- Doedens, Andrew -- Weidemann, Alexander -- Zhang, Na -- Takeda, Norihiko -- Greenberg, Joshua I -- Cheresh, David A -- Johnson, Randall S -- AI060840/AI/NIAID NIH HHS/ -- CA118165/CA/NCI NIH HHS/ -- CA82515/CA/NCI NIH HHS/ -- R01 CA082515/CA/NCI NIH HHS/ -- R01 CA082515-12/CA/NCI NIH HHS/ -- R01 CA118165/CA/NCI NIH HHS/ -- England -- Nature. 2008 Dec 11;456(7223):814-8. doi: 10.1038/nature07445.

    Description: Humans and other animals must often make decisions on the basis of imperfect evidence. Statisticians use measures such as P values to assign degrees of confidence to propositions, but little is known about how the brain computes confidence estimates about decisions. We explored this issue using behavioural analysis and neural recordings in rats in combination with computational modelling. Subjects were trained to perform an odour categorization task that allowed decision confidence to be manipulated by varying the distance of the test stimulus to the category boundary. To understand how confidence could be computed along with the choice itself, using standard models of decision-making, we defined a simple measure that quantified the quality of the evidence contributing to a particular decision. Here we show that the firing rates of many single neurons in the orbitofrontal cortex match closely to the predictions of confidence models and cannot be readily explained by alternative mechanisms, such as learning stimulus-outcome associations. Moreover, when tested using a delayed reward version of the task, we found that rats' willingness to wait for rewards increased with confidence, as predicted by the theoretical model. These results indicate that confidence estimates, previously suggested to require 'metacognition' and conscious awareness are available even in the rodent brain, can be computed with relatively simple operations, and can drive adaptive behaviour. We suggest that confidence estimation may be a fundamental and ubiquitous component of decision-making.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kepecs, Adam -- Uchida, Naoshige -- Zariwala, Hatim A -- Mainen, Zachary F -- England -- Nature. 2008 Sep 11;455(7210):227-31. doi: 10.1038/nature07200.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cold Spring Harbor Laboratory, 1 Bungtown Road, Cold Spring Harbor, New York 11724, USA. kepecs@cshl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18690210" target="_blank"〉PubMed〈/a〉
