    Beschreibung: Electrical microstimulation can establish causal links between the activity of groups of neurons and perceptual and cognitive functions. However, the number and identities of neurons microstimulated, as well as the number of action potentials evoked, are difficult to ascertain. To address these issues we introduced the light-gated algal channel channelrhodopsin-2 (ChR2) specifically into a small fraction of layer 2/3 neurons of the mouse primary somatosensory cortex. ChR2 photostimulation in vivo reliably generated stimulus-locked action potentials at frequencies up to 50 Hz. Here we show that naive mice readily learned to detect brief trains of action potentials (five light pulses, 1 ms, 20 Hz). After training, mice could detect a photostimulus firing a single action potential in approximately 300 neurons. Even fewer neurons (approximately 60) were required for longer stimuli (five action potentials, 250 ms). Our results show that perceptual decisions and learning can be driven by extremely brief epochs of cortical activity in a sparse subset of supragranular cortical pyramidal neurons.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3425380/" 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/PMC3425380/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huber, Daniel -- Petreanu, Leopoldo -- Ghitani, Nima -- Ranade, Sachin -- Hromadka, Tomas -- Mainen, Zach -- Svoboda, Karel -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 Jan 3;451(7174):61-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Janelia Farm Research Campus, Ashburn, Virginia 20147, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18094685" target="_blank"〉PubMed〈/a〉

    Beschreibung: Mating in many species induces a dramatic switch in female reproductive behaviour. In most insects, this switch is triggered by factors present in the male's seminal fluid. How these factors exert such profound effects in females is unknown. Here we identify a receptor for the Drosophila melanogaster sex peptide (SP, also known as Acp70A), the primary trigger of post-mating responses in this species. Females that lack the sex peptide receptor (SPR, also known as CG16752), either entirely or only in the nervous system, fail to respond to SP and continue to show virgin behaviours even after mating. SPR is expressed in the female's reproductive tract and central nervous system. The behavioural functions of SPR map to the subset of neurons that also express the fruitless gene, a key determinant of sex-specific reproductive behaviour. SPR is highly conserved across insects, opening up the prospect of new strategies to control the reproductive and host-seeking behaviours of agricultural pests and human disease vectors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yapici, Nilay -- Kim, Young-Joon -- Ribeiro, Carlos -- Dickson, Barry J -- England -- Nature. 2008 Jan 3;451(7174):33-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Institute of Molecular Pathology (IMP), Dr. Bohr-Gasse 7, A-1030 Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18066048" target="_blank"〉PubMed〈/a〉

    Beschreibung: Pluripotency pertains to the cells of early embryos that can generate all of the tissues in the organism. Embryonic stem cells are embryo-derived cell lines that retain pluripotency and represent invaluable tools for research into the mechanisms of tissue formation. Recently, murine fibroblasts have been reprogrammed directly to pluripotency by ectopic expression of four transcription factors (Oct4, Sox2, Klf4 and Myc) to yield induced pluripotent stem (iPS) cells. Using these same factors, we have derived iPS cells from fetal, neonatal and adult human primary cells, including dermal fibroblasts isolated from a skin biopsy of a healthy research subject. Human iPS cells resemble embryonic stem cells in morphology and gene expression and in the capacity to form teratomas in immune-deficient mice. These data demonstrate that defined factors can reprogramme human cells to pluripotency, and establish a method whereby patient-specific cells might be established in culture.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Park, In-Hyun -- Zhao, Rui -- West, Jason A -- Yabuuchi, Akiko -- Huo, Hongguang -- Ince, Tan A -- Lerou, Paul H -- Lensch, M William -- Daley, George Q -- England -- Nature. 2008 Jan 10;451(7175):141-6.

    Beschreibung: Population dynamics and evolutionary change are linked by the fundamental biological processes of birth and death. This means that population growth may correlate with the strength of selection, whereas evolutionary change can leave an ecological signature. We decompose population growth in an age-structured population into contributions from variation in a quantitative trait. We report that the distribution of body sizes within a population of Soay sheep can markedly influence population dynamics, accounting for up to one-fifth of observed population growth. Our results suggest that there is substantial opportunity for evolutionary dynamics to leave an ecological signature and visa versa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pelletier, Fanie -- Clutton-Brock, Tim -- Pemberton, Josephine -- Tuljapurkar, Shripad -- Coulson, Tim -- P01 AG 22500/AG/NIA NIH HHS/ -- P01 AG022500/AG/NIA NIH HHS/ -- P01 AG022500-04/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2007 Mar 16;315(5818):1571-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology and the Natural Environment Research Council (NERC) Centre for Population Biology, Imperial College London, Silwood Park, Ascot, Berkshire, SL5 7PY, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17363672" target="_blank"〉PubMed〈/a〉

    Beschreibung: Pleckstrin homology (PH) domain-mediated protein recruitment to cellular membranes is of paramount importance for signal transduction. The recruitment of many PH domains is controlled through production and turnover of their membrane ligand, phosphatidylinositol 3,4,5-trisphosphate (PIP3). We show that phosphorylation of the second messenger inositol 1,4,5-trisphosphate (IP3) into inositol 1,3,4,5-tetrakisphosphate (IP4) establishes another mode of PH domain regulation through a soluble ligand. At physiological concentrations, IP4 promoted PH domain binding to PIP3. In primary mouse CD4+CD8+ thymocytes, this was required for full activation of the protein tyrosine kinase Itk after T cell receptor engagement. Our data suggest that IP4 establishes a feedback loop of phospholipase C-gamma1 activation through Itk that is essential for T cell development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Yina H -- Grasis, Juris A -- Miller, Andrew T -- Xu, Ruo -- Soonthornvacharin, Stephen -- Andreotti, Amy H -- Tsoukas, Constantine D -- Cooke, Michael P -- Sauer, Karsten -- AR048848/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2007 May 11;316(5826):886-9.

    Beschreibung: The pre-B cell receptor (pre-BCR) serves as a checkpoint in B cell development. In the 2.7 angstrom structure of a human pre-BCR Fab-like fragment, consisting of an antibody heavy chain (HC) paired with the surrogate light chain, the "unique regions" of VpreB and lambda5 replace the complementarity-determining region 3 (CDR3) loop of an antibody light chain and appear to "probe" the HC CDR3, potentially influencing the selection of the antibody repertoire. Biochemical analysis indicates that the pre-BCR is impaired in its ability to recognize antigen, which, together with electron microscopic visualization of a pre-BCR dimer, suggests ligand-independent oligomerization as the likely signaling mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bankovich, Alexander J -- Raunser, Stefan -- Juo, Z Sean -- Walz, Thomas -- Davis, Mark M -- Garcia, K Christopher -- T32 AI007290/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2007 Apr 13;316(5822):291-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Immunology, Stanford University School of Medicine, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17431183" target="_blank"〉PubMed〈/a〉

    Beschreibung: Altruism-benefiting fellow group members at a cost to oneself-and parochialism-hostility toward individuals not of one's own ethnic, racial, or other group-are common human behaviors. The intersection of the two-which we term "parochial altruism"-is puzzling from an evolutionary perspective because altruistic or parochial behavior reduces one's payoffs by comparison to what one would gain by eschewing these behaviors. But parochial altruism could have evolved if parochialism promoted intergroup hostilities and the combination of altruism and parochialism contributed to success in these conflicts. Our game-theoretic analysis and agent-based simulations show that under conditions likely to have been experienced by late Pleistocene and early Holocene humans, neither parochialism nor altruism would have been viable singly, but by promoting group conflict, they could have evolved jointly.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Choi, Jung-Kyoo -- Bowles, Samuel -- New York, N.Y. -- Science. 2007 Oct 26;318(5850):636-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Economics and Trade, Kyungpook National University, 1370 Sankyuk-dong, Buk-gu, Daegu 702-701, Korea.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17962562" target="_blank"〉PubMed〈/a〉

    Beschreibung: Coronary heart disease (CHD) is a major cause of death in Western countries. We used genome-wide association scanning to identify a 58-kilobase interval on chromosome 9p21 that was consistently associated with CHD in six independent samples (more than 23,000 participants) from four Caucasian populations. This interval, which is located near the CDKN2A and CDKN2B genes, contains no annotated genes and is not associated with established CHD risk factors such as plasma lipoproteins, hypertension, or diabetes. Homozygotes for the risk allele make up 20 to 25% of Caucasians and have a approximately 30 to 40% increased risk of CHD.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2711874/" 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/PMC2711874/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McPherson, Ruth -- Pertsemlidis, Alexander -- Kavaslar, Nihan -- Stewart, Alexandre -- Roberts, Robert -- Cox, David R -- Hinds, David A -- Pennacchio, Len A -- Tybjaerg-Hansen, Anne -- Folsom, Aaron R -- Boerwinkle, Eric -- Hobbs, Helen H -- Cohen, Jonathan C -- HL-066681/HL/NHLBI NIH HHS/ -- HL-082896/HL/NHLBI NIH HHS/ -- R01 HL082896/HL/NHLBI NIH HHS/ -- R01 HL082896-02/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2007 Jun 8;316(5830):1488-91.

    Beschreibung: Differentiation of hepatic stellate cells (HSCs) to extracellular matrix- and growth factor-producing cells supports liver regeneration through promotion of hepatocyte proliferation. We show that the neurotrophin receptor p75NTR, a tumor necrosis factor receptor superfamily member expressed in HSCs after fibrotic and cirrhotic liver injury in humans, is a regulator of liver repair. In mice, depletion of p75NTR exacerbated liver pathology and inhibited hepatocyte proliferation in vivo. p75NTR-/- HSCs failed to differentiate to myofibroblasts and did not support hepatocyte proliferation. Moreover, inhibition of p75NTR signaling to the small guanosine triphosphatase Rho resulted in impaired HSC differentiation. Our results identify signaling from p75NTR to Rho as a mechanism for the regulation of HSC differentiation to regeneration-promoting cells that support hepatocyte proliferation in the diseased liver.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Passino, Melissa A -- Adams, Ryan A -- Sikorski, Shoana L -- Akassoglou, Katerina -- 5T32-GM07752/GM/NIGMS NIH HHS/ -- NS051470/NS/NINDS NIH HHS/ -- P30-NS047101/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2007 Mar 30;315(5820):1853-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of California, San Diego (UCSD), La Jolla, CA 92093-0636, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17395831" target="_blank"〉PubMed〈/a〉

    Beschreibung: The organization of chromatin affects all aspects of nuclear DNA metabolism in eukaryotes. H3.3 is an evolutionarily conserved histone variant and a key substrate for replication-independent chromatin assembly. Elimination of chromatin remodeling factor CHD1 in Drosophila embryos abolishes incorporation of H3.3 into the male pronucleus, renders the paternal genome unable to participate in zygotic mitoses, and leads to the development of haploid embryos. Furthermore, CHD1, but not ISWI, interacts with HIRA in cytoplasmic extracts. Our findings establish CHD1 as a major factor in replacement histone metabolism in the nucleus and reveal a critical role for CHD1 in the earliest developmental instances of genome-scale, replication-independent nucleosome assembly. Furthermore, our results point to the general requirement of adenosine triphosphate (ATP)-utilizing motor proteins for histone deposition in vivo.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3014568/" 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/PMC3014568/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Konev, Alexander Y -- Tribus, Martin -- Park, Sung Yeon -- Podhraski, Valerie -- Lim, Chin Yan -- Emelyanov, Alexander V -- Vershilova, Elena -- Pirrotta, Vincenzo -- Kadonaga, James T -- Lusser, Alexandra -- Fyodorov, Dmitry V -- GM58272/GM/NIGMS NIH HHS/ -- GM74233/GM/NIGMS NIH HHS/ -- R01 GM074233/GM/NIGMS NIH HHS/ -- Y 275/Austrian Science Fund FWF/Austria -- New York, N.Y. -- Science. 2007 Aug 24;317(5841):1087-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Albert Einstein College of Medicine, 1300 Morris Park Avenue, Bronx, NY 10461, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17717186" target="_blank"〉PubMed〈/a〉

    Beschreibung: Structural variation of the genome involves kilobase- to megabase-sized deletions, duplications, insertions, inversions, and complex combinations of rearrangements. We introduce high-throughput and massive paired-end mapping (PEM), a large-scale genome-sequencing method to identify structural variants (SVs) approximately 3 kilobases (kb) or larger that combines the rescue and capture of paired ends of 3-kb fragments, massive 454 sequencing, and a computational approach to map DNA reads onto a reference genome. PEM was used to map SVs in an African and in a putatively European individual and identified shared and divergent SVs relative to the reference genome. Overall, we fine-mapped more than 1000 SVs and documented that the number of SVs among humans is much larger than initially hypothesized; many of the SVs potentially affect gene function. The breakpoint junction sequences of more than 200 SVs were determined with a novel pooling strategy and computational analysis. Our analysis provided insights into the mechanisms of SV formation in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2674581/" 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/PMC2674581/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Korbel, Jan O -- Urban, Alexander Eckehart -- Affourtit, Jason P -- Godwin, Brian -- Grubert, Fabian -- Simons, Jan Fredrik -- Kim, Philip M -- Palejev, Dean -- Carriero, Nicholas J -- Du, Lei -- Taillon, Bruce E -- Chen, Zhoutao -- Tanzer, Andrea -- Saunders, A C Eugenia -- Chi, Jianxiang -- Yang, Fengtang -- Carter, Nigel P -- Hurles, Matthew E -- Weissman, Sherman M -- Harkins, Timothy T -- Gerstein, Mark B -- Egholm, Michael -- Snyder, Michael -- 077008/Wellcome Trust/United Kingdom -- 077014/Wellcome Trust/United Kingdom -- RR19895/RR/NCRR NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2007 Oct 19;318(5849):420-6.

    Beschreibung: Changes in the genes encoding sensory receptor proteins are an essential step in the evolution of new sensory capacities. In primates, trichromatic color vision evolved after changes in X chromosome-linked photopigment genes. To model this process, we studied knock-in mice that expressed a human long-wavelength-sensitive (L) cone photopigment in the form of an X-linked polymorphism. Behavioral tests demonstrated that heterozygous females, whose retinas contained both native mouse pigments and human L pigment, showed enhanced long-wavelength sensitivity and acquired a new capacity for chromatic discrimination. An inherent plasticity in the mammalian visual system thus permits the emergence of a new dimension of sensory experience based solely on gene-driven changes in receptor organization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jacobs, Gerald H -- Williams, Gary A -- Cahill, Hugh -- Nathans, Jeremy -- EY002052/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2007 Mar 23;315(5819):1723-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neuroscience Research Institute and Department of Psychology, University of California, Santa Barbara, CA 93106, USA. jacobs@psych.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17379811" target="_blank"〉PubMed〈/a〉

    Beschreibung: Negative associations between birth order and intelligence level have been found in numerous studies. The explanation for this relation is not clear, and several hypotheses have been suggested. One family of hypotheses suggests that the relation is due to more-favorable family interaction and stimulation of low-birth-order children, whereas others claim that the effect is caused by prenatal gestational factors. We show that intelligence quotient (IQ) score levels among nearly 250,000 military conscripts were dependent on social rank in the family and not on birth order as such, providing support for a family interaction explanation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kristensen, Petter -- Bjerkedal, Tor -- New York, N.Y. -- Science. 2007 Jun 22;316(5832):1717.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Occupational Health, N-0033 Oslo, Norway. petter.kristensen@stami.no〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17588924" target="_blank"〉PubMed〈/a〉

    Beschreibung: The in vivo potential of neural stem cells in the postnatal mouse brain is not known, but because they produce many different types of neurons, they must be either very versatile or very diverse. By specifically targeting stem cells and following their progeny in vivo, we showed that postnatal stem cells in different regions produce different types of neurons, even when heterotopically grafted or grown in culture. This suggests that rather than being plastic and homogeneous, neural stem cells are a restricted and diverse population of progenitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Merkle, Florian T -- Mirzadeh, Zaman -- Alvarez-Buylla, Arturo -- New York, N.Y. -- Science. 2007 Jul 20;317(5836):381-4.

    Beschreibung: The limb blastemal cells of an adult salamander regenerate the structures distal to the level of amputation, and the surface protein Prod 1 is a critical determinant of their proximodistal identity. The anterior gradient protein family member nAG is a secreted ligand for Prod 1 and a growth factor for cultured newt blastemal cells. nAG is sequentially expressed after amputation in the regenerating nerve and the wound epidermis-the key tissues of the stem cell niche-and its expression in both locations is abrogated by denervation. The local expression of nAG after electroporation is sufficient to rescue a denervated blastema and regenerate the distal structures. Our analysis brings together the positional identity of the blastema and the classical nerve dependence of limb regeneration.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2696928/" 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/PMC2696928/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kumar, Anoop -- Godwin, James W -- Gates, Phillip B -- Garza-Garcia, A Acely -- Brockes, Jeremy P -- G0600229/Medical Research Council/United Kingdom -- G0600229(77696)/Medical Research Council/United Kingdom -- G9537983/Medical Research Council/United Kingdom -- G9537983(56733)/Medical Research Council/United Kingdom -- MC_U117574559/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2007 Nov 2;318(5851):772-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, University College London, Gower Street, London WC1E 6BT, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17975060" target="_blank"〉PubMed〈/a〉

    Beschreibung: Obesity is a serious international health problem that increases the risk of several common diseases. The genetic factors predisposing to obesity are poorly understood. A genome-wide search for type 2 diabetes-susceptibility genes identified a common variant in the FTO (fat mass and obesity associated) gene that predisposes to diabetes through an effect on body mass index (BMI). An additive association of the variant with BMI was replicated in 13 cohorts with 38,759 participants. The 16% of adults who are homozygous for the risk allele weighed about 3 kilograms more and had 1.67-fold increased odds of obesity when compared with those not inheriting a risk allele. This association was observed from age 7 years upward and reflects a specific increase in fat mass.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2646098/" 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/PMC2646098/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frayling, Timothy M -- Timpson, Nicholas J -- Weedon, Michael N -- Zeggini, Eleftheria -- Freathy, Rachel M -- Lindgren, Cecilia M -- Perry, John R B -- Elliott, Katherine S -- Lango, Hana -- Rayner, Nigel W -- Shields, Beverley -- Harries, Lorna W -- Barrett, Jeffrey C -- Ellard, Sian -- Groves, Christopher J -- Knight, Bridget -- Patch, Ann-Marie -- Ness, Andrew R -- Ebrahim, Shah -- Lawlor, Debbie A -- Ring, Susan M -- Ben-Shlomo, Yoav -- Jarvelin, Marjo-Riitta -- Sovio, Ulla -- Bennett, Amanda J -- Melzer, David -- Ferrucci, Luigi -- Loos, Ruth J F -- Barroso, Ines -- Wareham, Nicholas J -- Karpe, Fredrik -- Owen, Katharine R -- Cardon, Lon R -- Walker, Mark -- Hitman, Graham A -- Palmer, Colin N A -- Doney, Alex S F -- Morris, Andrew D -- Smith, George Davey -- Hattersley, Andrew T -- McCarthy, Mark I -- 079557/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- G0000934/Medical Research Council/United Kingdom -- G0500070/Medical Research Council/United Kingdom -- G0600705/Medical Research Council/United Kingdom -- G9815508/Medical Research Council/United Kingdom -- MC_U106179471/Medical Research Council/United Kingdom -- MC_U106188470/Medical Research Council/United Kingdom -- Z99 AG999999/Intramural NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2007 May 11;316(5826):889-94.

    Beschreibung: The 66-kilodalton isoform of the growth factor adapter Shc (p66Shc) translates oxidative damage into cell death by acting as reactive oxygen species (ROS) producer within mitochondria. However, the signaling link between cellular stress and mitochondrial proapoptotic activity of p66Shc was not known. We demonstrate that protein kinase C beta, activated by oxidative conditions in the cell, induces phosphorylation of p66Shc and triggers mitochondrial accumulation of the protein after it is recognized by the prolyl isomerase Pin1. Once imported, p66Shc causes alterations of mitochondrial Ca2+ responses and three-dimensional structure, thus inducing apoptosis. These data identify a signaling route that activates an apoptotic inducer shortening the life span and could be a potential target of pharmacological approaches to inhibit aging.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pinton, Paolo -- Rimessi, Alessandro -- Marchi, Saverio -- Orsini, Francesca -- Migliaccio, Enrica -- Giorgio, Marco -- Contursi, Cristina -- Minucci, Saverio -- Mantovani, Fiamma -- Wieckowski, Mariusz R -- Del Sal, Giannino -- Pelicci, Pier Giuseppe -- Rizzuto, Rosario -- GGP05284/Telethon/Italy -- New York, N.Y. -- Science. 2007 Feb 2;315(5812):659-63.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental and Diagnostic Medicine, Section of General Pathology and Interdisciplinary Center for the Study of Inflammation (ICSI), University of Ferrara, Ferrera, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17272725" target="_blank"〉PubMed〈/a〉

    Beschreibung: Early specification of endomesodermal territories in the sea urchin embryo depends on a moving torus of regulatory gene expression. We show how this dynamic patterning function is encoded in a gene regulatory network (GRN) subcircuit that includes the otx, wnt8, and blimp1 genes, the cis-regulatory control systems of which have all been experimentally defined. A cis-regulatory reconstruction experiment revealed that blimp1 autorepression accounts for progressive extinction of expression in the center of the torus, whereas its outward expansion follows reception of the Wnt8 ligand by adjacent cells. GRN circuitry thus controls not only static spatial assignment in development but also dynamic regulatory patterning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, Joel -- Theodoris, Christina -- Davidson, Eric H -- HD-37105/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 2;318(5851):794-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, 156-29, California Institute of Technology, Pasadena, CA 91125, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17975065" target="_blank"〉PubMed〈/a〉

    Beschreibung: A central issue in the regulation of apoptosis by the Bcl-2 family is whether its BH3-only members initiate apoptosis by directly binding to the essential cell-death mediators Bax and Bak, or whether they can act indirectly, by engaging their pro-survival Bcl-2-like relatives. Contrary to the direct-activation model, we show that Bax and Bak can mediate apoptosis without discernable association with the putative BH3-only activators (Bim, Bid, and Puma), even in cells with no Bim or Bid and reduced Puma. Our results indicate that BH3-only proteins induce apoptosis at least primarily by engaging the multiple pro-survival relatives guarding Bax and Bak.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Willis, Simon N -- Fletcher, Jamie I -- Kaufmann, Thomas -- van Delft, Mark F -- Chen, Lin -- Czabotar, Peter E -- Ierino, Helen -- Lee, Erinna F -- Fairlie, W Douglas -- Bouillet, Philippe -- Strasser, Andreas -- Kluck, Ruth M -- Adams, Jerry M -- Huang, David C S -- CA43540/CA/NCI NIH HHS/ -- CA80188/CA/NCI NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2007 Feb 9;315(5813):856-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Walter and Eliza Hall Institute of Medical Research, 1G Royal Parade, Parkville, Victoria 3050, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17289999" target="_blank"〉PubMed〈/a〉

    Beschreibung: The roles of endocannabinoid signaling during central nervous system development are unknown. We report that CB(1) cannabinoid receptors (CB(1)Rs) are enriched in the axonal growth cones of gamma-aminobutyric acid-containing (GABAergic) interneurons in the rodent cortex during late gestation. Endocannabinoids trigger CB(1)R internalization and elimination from filopodia and induce chemorepulsion and collapse of axonal growth cones of these GABAergic interneurons by activating RhoA. Similarly, endocannabinoids diminish the galvanotropism of Xenopus laevis spinal neurons. These findings, together with the impaired target selection of cortical GABAergic interneurons lacking CB(1)Rs, identify endocannabinoids as axon guidance cues and demonstrate that endocannabinoid signaling regulates synaptogenesis and target selection in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berghuis, Paul -- Rajnicek, Ann M -- Morozov, Yury M -- Ross, Ruth A -- Mulder, Jan -- Urban, Gabriella M -- Monory, Krisztina -- Marsicano, Giovanni -- Matteoli, Michela -- Canty, Alison -- Irving, Andrew J -- Katona, Istvan -- Yanagawa, Yuchio -- Rakic, Pasko -- Lutz, Beat -- Mackie, Ken -- Harkany, Tibor -- DA00286/DA/NIDA NIH HHS/ -- DA015916/DA/NIDA NIH HHS/ -- DA11322/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2007 May 25;316(5828):1212-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Neurobiology, Department of Medical Biochemistry and Biophysics, Karolinska Institutet, S-17177 Stockholm, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17525344" target="_blank"〉PubMed〈/a〉

    Beschreibung: Research on sexual selection shows that the evolution of secondary sexual characters in males and the distribution of sex differences are more complex than was initially suggested but does not undermine our understanding of the evolutionary mechanisms involved. However, the operation of sexual selection in females has still received relatively little attention. Recent studies show that both intrasexual competition between females and male choice of mating partners are common, leading to strong sexual selection in females and, in extreme cases, to reversals in the usual pattern of sex differences in behavior and morphology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clutton-Brock, Tim -- New York, N.Y. -- Science. 2007 Dec 21;318(5858):1882-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Cambridge, Downing Street, Cambridge CB2 3EJ, UK. thcb@cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18096798" target="_blank"〉PubMed〈/a〉

    Beschreibung: The mechanisms controlling the establishment of the embryonic-abembryonic (E-Ab) axis of the mammalian blastocyst are controversial. We used in vitro time-lapse imaging and in vivo lineage labeling to provide evidence that the E-Ab axis of the mouse blastocyst is generated independently of early cell lineage. Rather, both the boundary between two-cell blastomeres and the E-Ab axis of the blastocyst align relative to the ellipsoidal shape of the zona pellucida (ZP), an extraembryonic structure. Lack of correlation between cell lineage and the E-Ab axis can be explained by the rotation of the embryo within the ZP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kurotaki, Yoko -- Hatta, Kohei -- Nakao, Kazuki -- Nabeshima, Yo-Ichi -- Fujimori, Toshihiko -- New York, N.Y. -- Science. 2007 May 4;316(5825):719-23.

    Beschreibung: The Staphylococcus aureus Panton-Valentine leukocidin (PVL) is a pore-forming toxin secreted by strains epidemiologically associated with the current outbreak of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) and with the often-lethal necrotizing pneumonia. To investigate the role of PVL in pulmonary disease, we tested the pathogenicity of clinical isolates, isogenic PVL-negative and PVL-positive S. aureus strains, as well as purified PVL, in a mouse acute pneumonia model. Here we show that PVL is sufficient to cause pneumonia and that the expression of this leukotoxin induces global changes in transcriptional levels of genes encoding secreted and cell wall-anchored staphylococcal proteins, including the lung inflammatory factor staphylococcal protein A (Spa).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Labandeira-Rey, Maria -- Couzon, Florence -- Boisset, Sandrine -- Brown, Eric L -- Bes, Michele -- Benito, Yvonne -- Barbu, Elena M -- Vazquez, Vanessa -- Hook, Magnus -- Etienne, Jerome -- Vandenesch, Francois -- Bowden, M Gabriela -- AI020624/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2007 Feb 23;315(5815):1130-3.

    Beschreibung: Mutations affecting the BRCT domains of the breast cancer-associated tumor suppressor BRCA1 disrupt the recruitment of this protein to DNA double-strand breaks (DSBs). The molecular structures at DSBs recognized by BRCA1 are presently unknown. We report the interaction of the BRCA1 BRCT domain with RAP80, a ubiquitin-binding protein. RAP80 targets a complex containing the BRCA1-BARD1 (BRCA1-associated ring domain protein 1) E3 ligase and the deubiquitinating enzyme (DUB) BRCC36 to MDC1-gammaH2AX-dependent lysine(6)- and lysine(63)-linked ubiquitin polymers at DSBs. These events are required for cell cycle checkpoint and repair responses to ionizing radiation, implicating ubiquitin chain recognition and turnover in the BRCA1-mediated repair of DSBs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2706583/" 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/PMC2706583/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sobhian, Bijan -- Shao, Genze -- Lilli, Dana R -- Culhane, Aedin C -- Moreau, Lisa A -- Xia, Bing -- Livingston, David M -- Greenberg, Roger A -- K08 CA106597/CA/NCI NIH HHS/ -- K08 CA106597-01A2/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2007 May 25;316(5828):1198-202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute and Department of Genetics and Department of Medicine, Harvard Medical School, 44 Binney Street, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17525341" target="_blank"〉PubMed〈/a〉

    Beschreibung: The insect order of Hymenoptera (ants, bees, sawflies, and wasps) consists almost entirely of haplodiploid species. Under haplodiploidy, males develop from unfertilized eggs and are haploid, whereas females develop from fertilized eggs and are diploid. Although diploid males commonly occur, haploid females have never been reported. In analyzing the phenomenon of gynandromorphism in the parasitoid wasp Nasonia vitripennis, we found a line that generates complete phenotypic females from unfertilized eggs. These females have ovaries, can lay eggs, and are haploid, as shown by cytological and flow cytometric analyses. The data show that diploidy is not necessary for female development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beukeboom, Leo W -- Kamping, Albert -- Louter, Marina -- Pijnacker, Laas P -- Katju, Vaishali -- Ferree, Patrick M -- Werren, John H -- 5 RO1 GM070026-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Jan 12;315(5809):206.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Evolutionary Genetics, Centre for Ecological and Evolutionary Studies, University of Groningen, Post Office Box 14, 9750 AA Haren, Netherlands. l.w.beukeboom@rug.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17218519" target="_blank"〉PubMed〈/a〉

    Beschreibung: Human cancer is caused by the accumulation of mutations in oncogenes and tumor suppressor genes. To catalog the genetic changes that occur during tumorigenesis, we isolated DNA from 11 breast and 11 colorectal tumors and determined the sequences of the genes in the Reference Sequence database in these samples. Based on analysis of exons representing 20,857 transcripts from 18,191 genes, we conclude that the genomic landscapes of breast and colorectal cancers are composed of a handful of commonly mutated gene "mountains" and a much larger number of gene "hills" that are mutated at low frequency. We describe statistical and bioinformatic tools that may help identify mutations with a role in tumorigenesis. These results have implications for understanding the nature and heterogeneity of human cancers and for using personal genomics for tumor diagnosis and therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wood, Laura D -- Parsons, D Williams -- Jones, Sian -- Lin, Jimmy -- Sjoblom, Tobias -- Leary, Rebecca J -- Shen, Dong -- Boca, Simina M -- Barber, Thomas -- Ptak, Janine -- Silliman, Natalie -- Szabo, Steve -- Dezso, Zoltan -- Ustyanksky, Vadim -- Nikolskaya, Tatiana -- Nikolsky, Yuri -- Karchin, Rachel -- Wilson, Paul A -- Kaminker, Joshua S -- Zhang, Zemin -- Croshaw, Randal -- Willis, Joseph -- Dawson, Dawn -- Shipitsin, Michail -- Willson, James K V -- Sukumar, Saraswati -- Polyak, Kornelia -- Park, Ben Ho -- Pethiyagoda, Charit L -- Pant, P V Krishna -- Ballinger, Dennis G -- Sparks, Andrew B -- Hartigan, James -- Smith, Douglas R -- Suh, Erick -- Papadopoulos, Nickolas -- Buckhaults, Phillip -- Markowitz, Sanford D -- Parmigiani, Giovanni -- Kinzler, Kenneth W -- Velculescu, Victor E -- Vogelstein, Bert -- CA 43460/CA/NCI NIH HHS/ -- CA 57345/CA/NCI NIH HHS/ -- CA109274/CA/NCI NIH HHS/ -- CA112828/CA/NCI NIH HHS/ -- CA121113/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- GM070219/GM/NIGMS NIH HHS/ -- GM07309/GM/NIGMS NIH HHS/ -- P30-CA43703/CA/NCI NIH HHS/ -- RR017698/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 16;318(5853):1108-13.

    Beschreibung: Migrating cells extend protrusions, probing the surrounding matrix in search of permissive sites to form adhesions. We found that actin fibers polymerizing along the leading edge directed local protrusions and drove synchronous sideways movement of beta1 integrin adhesion receptors. These movements lead to the clustering and positioning of conformationally activated, but unligated, beta1 integrins along the leading edge of fibroblast lamellae and growth cone filopodia. Thus, rapid actin-based movement of primed integrins along the leading edge suggests a "sticky fingers" mechanism to probe for new adhesion sites and to direct migration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Galbraith, Catherine G -- Yamada, Kenneth M -- Galbraith, James A -- New York, N.Y. -- Science. 2007 Feb 16;315(5814):992-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Dental and Craniofacial Research, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17303755" target="_blank"〉PubMed〈/a〉

    Beschreibung: Although expansion of trinucleotide repeats accounts for over 30 human diseases, mechanisms of repeat instability remain poorly understood. We show that a Drosophila model for the CAG/polyglutamine (polyQ) disease spinocerebellar ataxia type 3 recapitulates key features of human CAG-repeat instability, including large repeat changes and strong expansion bias. Instability is dramatically enhanced by transcription and modulated by nuclear excision repair and a regulator of DNA repair adenosine 3',5'-monophosphate (cAMP) response element-binding protein (CREB)-binding protein-a histone acetyltransferase (HAT) whose decreased activity contributes to polyQ disease. Pharmacological treatment to normalize acetylation suppressed instability. Thus, toxic consequences of pathogenic polyQ protein may include enhancing repeat instability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jung, Joonil -- Bonini, Nancy -- New York, N.Y. -- Science. 2007 Mar 30;315(5820):1857-9.

    Beschreibung: Platelets are generated from megakaryocytes (MKs) in mammalian bone marrow (BM) by mechanisms that remain poorly understood. Here we describe the use of multiphoton intravital microscopy in intact BM to visualize platelet generation in mice. MKs were observed as sessile cells that extended dynamic proplatelet-like protrusions into microvessels. These intravascular extensions appeared to be sheared from their transendothelial stems by flowing blood, resulting in the appearance of proplatelets in peripheral blood. In vitro, proplatelet production from differentiating MKs was enhanced by fluid shear. These results confirm the concept of proplatelet formation in vivo and are consistent with the possibility that blood flow-induced hydrodynamic shear stress is a biophysical determinant of thrombopoiesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Junt, Tobias -- Schulze, Harald -- Chen, Zhao -- Massberg, Steffen -- Goerge, Tobias -- Krueger, Andreas -- Wagner, Denisa D -- Graf, Thomas -- Italiano, Joseph E Jr -- Shivdasani, Ramesh A -- von Andrian, Ulrich H -- HL068130/HL/NHLBI NIH HHS/ -- HL56949/HL/NHLBI NIH HHS/ -- HL63143/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2007 Sep 21;317(5845):1767-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immune Disease Institute and Department of Pathology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17885137" target="_blank"〉PubMed〈/a〉

    Beschreibung: The catalytic (C) subunit of cyclic adenosine monophosphate (cAMP)-dependent protein kinase (PKA) is inhibited by two classes of regulatory subunits, RI and RII. The RII subunits are substrates as well as inhibitors and do not require adenosine triphosphate (ATP) to form holoenzyme, which distinguishes them from RI subunits. To understand the molecular basis for isoform diversity, we solved the crystal structure of an RIIalpha holoenzyme and compared it to the RIalpha holoenzyme. Unphosphorylated RIIalpha(90-400), a deletion mutant, undergoes major conformational changes as both of the cAMP-binding domains wrap around the C subunit's large lobe. The hallmark of this conformational reorganization is the helix switch in domain A. The C subunit is in an open conformation, and its carboxyl-terminal tail is disordered. This structure demonstrates the conserved and isoform-specific features of RI and RII and the importance of ATP, and also provides a new paradigm for designing isoform-specific activators or antagonists for PKA.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4036697/" 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/PMC4036697/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Jian -- Brown, Simon H J -- von Daake, Sventja -- Taylor, Susan S -- GM34921/GM/NIGMS NIH HHS/ -- R01 GM034921/GM/NIGMS NIH HHS/ -- R01 GM034921-23/GM/NIGMS NIH HHS/ -- T32-CA009524/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):274-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of California, San Diego, La Jolla, CA 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932298" target="_blank"〉PubMed〈/a〉

    Beschreibung: Primary pneumonic plague is transmitted easily, progresses rapidly, and causes high mortality, but the mechanisms by which Yersinia pestis overwhelms the lungs are largely unknown. We show that the plasminogen activator Pla is essential for Y. pestis to cause primary pneumonic plague but is less important for dissemination during pneumonic plague than during bubonic plague. Experiments manipulating its temporal expression showed that Pla allows Y. pestis to replicate rapidly in the airways, causing a lethal fulminant pneumonia; if unexpressed, inflammation is aborted, and lung repair is activated. Inhibition of Pla expression prolonged the survival of animals with the disease, offering a therapeutic option to extend the period during which antibiotics are effective.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lathem, Wyndham W -- Price, Paul A -- Miller, Virginia L -- Goldman, William E -- AI53298/AI/NIAID NIH HHS/ -- DK52574/DK/NIDDK NIH HHS/ -- F32 AI069688-01/AI/NIAID NIH HHS/ -- NRSA T32 GM07067/GM/NIGMS NIH HHS/ -- U54 AI057160/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2007 Jan 26;315(5811):509-13.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Microbiology, Washington University School of Medicine, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17255510" target="_blank"〉PubMed〈/a〉

    Beschreibung: During pregnancy, maternal pancreatic islets grow to match dynamic physiological demands, but the mechanisms regulating adaptive islet growth in this setting are poorly understood. Here we show that menin, a protein previously characterized as an endocrine tumor suppressor and transcriptional regulator, controls islet growth in pregnant mice. Pregnancy stimulated proliferation of maternal pancreatic islet beta-cells that was accompanied by reduced islet levels of menin and its targets. Transgenic expression of menin in maternal beta-cells prevented islet expansion and led to hyperglycemia and impaired glucose tolerance, hallmark features of gestational diabetes. Prolactin, a hormonal regulator of pregnancy, repressed islet menin levels and stimulated beta-cell proliferation. These results expand our understanding of mechanisms underlying diabetes pathogenesis and reveal potential targets for therapy in diabetes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karnik, Satyajit K -- Chen, Hainan -- McLean, Graeme W -- Heit, Jeremy J -- Gu, Xueying -- Zhang, Andrew Y -- Fontaine, Magali -- Yen, Michael H -- Kim, Seung K -- T32DK007217-32/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 2;318(5851):806-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental Biology, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17975067" target="_blank"〉PubMed〈/a〉

    Beschreibung: Sex in reptiles is determined by genes on sex chromosomes or by incubation temperature. Previously these two modes were thought to be distinct, yet we show that high incubation temperatures reverse genotypic males (ZZ) to phenotypic females in a lizard with ZZ and ZW sex chromosomes. Thus, the W chromosome is not necessary for female differentiation. Sex determination is probably via a dosage-sensitive male-determining gene on the Z chromosome that is inactivated by extreme temperatures. Our data invite a novel hypothesis for the evolution of temperature-dependent sex determination (TSD) and suggest that sex chromosomes may exist in many TSD reptiles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Quinn, Alexander E -- Georges, Arthur -- Sarre, Stephen D -- Guarino, Fiorenzo -- Ezaz, Tariq -- Graves, Jennifer A Marshall -- New York, N.Y. -- Science. 2007 Apr 20;316(5823):411.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Applied Ecology, University of Canberra, ACT 2601, Australia. quinn@aerg.canberra.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17446395" target="_blank"〉PubMed〈/a〉

However, their analysis raises two statistical concerns. When these concerns are addressed, few genes with significantly elevated mutation rates remain.

    Beschreibung: Artificial biochemical circuits are likely to play as large a role in biological engineering as electrical circuits have played in the engineering of electromechanical devices. Toward that end, nucleic acids provide a designable substrate for the regulation of biochemical reactions. However, it has been difficult to incorporate signal amplification components. We introduce a design strategy that allows a specified input oligonucleotide to catalyze the release of a specified output oligonucleotide, which in turn can serve as a catalyst for other reactions. This reaction, which is driven forward by the configurational entropy of the released molecule, provides an amplifying circuit element that is simple, fast, modular, composable, and robust. We have constructed and characterized several circuits that amplify nucleic acid signals, including a feedforward cascade with quadratic kinetics and a positive feedback circuit with exponential growth kinetics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, David Yu -- Turberfield, Andrew J -- Yurke, Bernard -- Winfree, Erik -- New York, N.Y. -- Science. 2007 Nov 16;318(5853):1121-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Computation and Neural Systems, California Institute of Technology, MC 136-93, 1200 East California Boulevard, Pasadena, CA91125, USA. dzhang@dna.caltech.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18006742" target="_blank"〉PubMed〈/a〉

    Beschreibung: The normal synovium forms a membrane at the edges of joints and provides lubrication and nutrients for the cartilage. In rheumatoid arthritis, the synovium is the site of inflammation, and it participates in an organized tissue response that damages cartilage and bone. We identified cadherin-11 as essential for the development of the synovium. Cadherin-11-deficient mice have a hypoplastic synovial lining, display a disorganized synovial reaction to inflammation, and are resistant to inflammatory arthritis. Cadherin-11 therapeutics prevent and reduce arthritis in mouse models. Thus, synovial cadherin-11 determines the behavior of synovial cells in their proinflammatory and destructive tissue response in inflammatory arthritis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, David M -- Kiener, Hans P -- Agarwal, Sandeep K -- Noss, Erika H -- Watts, Gerald F M -- Chisaka, Osamu -- Takeichi, Masatoshi -- Brenner, Michael B -- K08 AR2214/AR/NIAMS NIH HHS/ -- R01 AR48114/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Feb 16;315(5814):1006-10.

    Beschreibung: The rhesus macaque (Macaca mulatta) is an abundant primate species that diverged from the ancestors of Homo sapiens about 25 million years ago. Because they are genetically and physiologically similar to humans, rhesus monkeys are the most widely used nonhuman primate in basic and applied biomedical research. We determined the genome sequence of an Indian-origin Macaca mulatta female and compared the data with chimpanzees and humans to reveal the structure of ancestral primate genomes and to identify evidence for positive selection and lineage-specific expansions and contractions of gene families. A comparison of sequences from individual animals was used to investigate their underlying genetic diversity. The complete description of the macaque genome blueprint enhances the utility of this animal model for biomedical research and improves our understanding of the basic biology of the species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rhesus Macaque Genome Sequencing and Analysis Consortium -- Gibbs, Richard A -- Rogers, Jeffrey -- Katze, Michael G -- Bumgarner, Roger -- Weinstock, George M -- Mardis, Elaine R -- Remington, Karin A -- Strausberg, Robert L -- Venter, J Craig -- Wilson, Richard K -- Batzer, Mark A -- Bustamante, Carlos D -- Eichler, Evan E -- Hahn, Matthew W -- Hardison, Ross C -- Makova, Kateryna D -- Miller, Webb -- Milosavljevic, Aleksandar -- Palermo, Robert E -- Siepel, Adam -- Sikela, James M -- Attaway, Tony -- Bell, Stephanie -- Bernard, Kelly E -- Buhay, Christian J -- Chandrabose, Mimi N -- Dao, Marvin -- Davis, Clay -- Delehaunty, Kimberly D -- Ding, Yan -- Dinh, Huyen H -- Dugan-Rocha, Shannon -- Fulton, Lucinda A -- Gabisi, Ramatu Ayiesha -- Garner, Toni T -- Godfrey, Jennifer -- Hawes, Alicia C -- Hernandez, Judith -- Hines, Sandra -- Holder, Michael -- Hume, Jennifer -- Jhangiani, Shalini N -- Joshi, Vandita -- Khan, Ziad Mohid -- Kirkness, Ewen F -- Cree, Andrew -- Fowler, R Gerald -- Lee, Sandra -- Lewis, Lora R -- Li, Zhangwan -- Liu, Yih-Shin -- Moore, Stephanie M -- Muzny, Donna -- Nazareth, Lynne V -- Ngo, Dinh Ngoc -- Okwuonu, Geoffrey O -- Pai, Grace -- Parker, David -- Paul, Heidie A -- Pfannkoch, Cynthia -- Pohl, Craig S -- Rogers, Yu-Hui -- Ruiz, San Juana -- Sabo, Aniko -- Santibanez, Jireh -- Schneider, Brian W -- Smith, Scott M -- Sodergren, Erica -- Svatek, Amanda F -- Utterback, Teresa R -- Vattathil, Selina -- Warren, Wesley -- White, Courtney Sherell -- Chinwalla, Asif T -- Feng, Yucheng -- Halpern, Aaron L -- Hillier, Ladeana W -- Huang, Xiaoqiu -- Minx, Pat -- Nelson, Joanne O -- Pepin, Kymberlie H -- Qin, Xiang -- Sutton, Granger G -- Venter, Eli -- Walenz, Brian P -- Wallis, John W -- Worley, Kim C -- Yang, Shiaw-Pyng -- Jones, Steven M -- Marra, Marco A -- Rocchi, Mariano -- Schein, Jacqueline E -- Baertsch, Robert -- Clarke, Laura -- Csuros, Miklos -- Glasscock, Jarret -- Harris, R Alan -- Havlak, Paul -- Jackson, Andrew R -- Jiang, Huaiyang -- Liu, Yue -- Messina, David N -- Shen, Yufeng -- Song, Henry Xing-Zhi -- Wylie, Todd -- Zhang, Lan -- Birney, Ewan -- Han, Kyudong -- Konkel, Miriam K -- Lee, Jungnam -- Smit, Arian F A -- Ullmer, Brygg -- Wang, Hui -- Xing, Jinchuan -- Burhans, Richard -- Cheng, Ze -- Karro, John E -- Ma, Jian -- Raney, Brian -- She, Xinwei -- Cox, Michael J -- Demuth, Jeffery P -- Dumas, Laura J -- Han, Sang-Gook -- Hopkins, Janet -- Karimpour-Fard, Anis -- Kim, Young H -- Pollack, Jonathan R -- Vinar, Tomas -- Addo-Quaye, Charles -- Degenhardt, Jeremiah -- Denby, Alexandra -- Hubisz, Melissa J -- Indap, Amit -- Kosiol, Carolin -- Lahn, Bruce T -- Lawson, Heather A -- Marklein, Alison -- Nielsen, Rasmus -- Vallender, Eric J -- Clark, Andrew G -- Ferguson, Betsy -- Hernandez, Ryan D -- Hirani, Kashif -- Kehrer-Sawatzki, Hildegard -- Kolb, Jessica -- Patil, Shobha -- Pu, Ling-Ling -- Ren, Yanru -- Smith, David Glenn -- Wheeler, David A -- Schenck, Ian -- Ball, Edward V -- Chen, Rui -- Cooper, David N -- Giardine, Belinda -- Hsu, Fan -- Kent, W James -- Lesk, Arthur -- Nelson, David L -- O'brien, William E -- Prufer, Kay -- Stenson, Peter D -- Wallace, James C -- Ke, Hui -- Liu, Xiao-Ming -- Wang, Peng -- Xiang, Andy Peng -- Yang, Fan -- Barber, Galt P -- Haussler, David -- Karolchik, Donna -- Kern, Andy D -- Kuhn, Robert M -- Smith, Kayla E -- Zwieg, Ann S -- 062023/Wellcome Trust/United Kingdom -- R01 HG002939/HG/NHGRI NIH HHS/ -- U54 HG003068/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2007 Apr 13;316(5822):222-34.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Genome Sequencing Center, Baylor College of Medicine, Houston, TX 77030, USA. agibbs@bcm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17431167" target="_blank"〉PubMed〈/a〉

    Beschreibung: PDZ domains have long been thought to cluster into discrete functional classes defined by their peptide-binding preferences. We used protein microarrays and quantitative fluorescence polarization to characterize the binding selectivity of 157 mouse PDZ domains with respect to 217 genome-encoded peptides. We then trained a multidomain selectivity model to predict PDZ domain-peptide interactions across the mouse proteome with an accuracy that exceeds many large-scale, experimental investigations of protein-protein interactions. Contrary to the current paradigm, PDZ domains do not fall into discrete classes; instead, they are evenly distributed throughout selectivity space, which suggests that they have been optimized across the proteome to minimize cross-reactivity. We predict that focusing on families of interaction domains, which facilitates the integration of experimentation and modeling, will play an increasingly important role in future investigations of protein function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2674608/" 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/PMC2674608/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stiffler, Michael A -- Chen, Jiunn R -- Grantcharova, Viara P -- Lei, Ying -- Fuchs, Daniel -- Allen, John E -- Zaslavskaia, Lioudmila A -- MacBeath, Gavin -- 1 RO1 GM072872-01/GM/NIGMS NIH HHS/ -- 5 T32 GM07598-25/GM/NIGMS NIH HHS/ -- R01 GM072872/GM/NIGMS NIH HHS/ -- R01 GM072872-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Jul 20;317(5836):364-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Harvard University, 12 Oxford Street, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17641200" target="_blank"〉PubMed〈/a〉

    Beschreibung: Plasmacytoid dendritic cells (pDCs) detect viruses in the acidified endosomes by means of Toll-like receptors (TLRs). Yet, pDC responses to certain single-stranded RNA (ssRNA) viruses occur only after live viral infection. We present evidence here that the recognition of such viruses by TLR7 requires transport of cytosolic viral replication intermediates into the lysosome by the process of autophagy. In addition, autophagy was found to be required for the production of interferon-alpha by pDCs. These results support a key role for autophagy in mediating ssRNA virus detection and interferon-alpha secretion by pDCs and suggest that cytosolic replication intermediates of viruses serve as pathogen signatures recognized by TLR7.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Heung Kyu -- Lund, Jennifer M -- Ramanathan, Balaji -- Mizushima, Noboru -- Iwasaki, Akiko -- AI054359/AI/NIAID NIH HHS/ -- AI064705/AI/NIAID NIH HHS/ -- AI07019/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2007 Mar 9;315(5817):1398-401.

    Beschreibung: Inflammation is increasingly recognized as an important component of tumorigenesis, although the mechanisms and pathways involved are not well understood. Tumor development is regulated by products of several modifier genes, but instructions for their tumor-specific expression are currently unknown. We show that the signaling through the adaptor protein MyD88 has a critical role in spontaneous tumor development in mice with heterozygous mutation in the adenomatous polyposis coli (APC) gene. We found that MyD88-dependent signaling controls the expression of several key modifier genes of intestinal tumorigenesis and has a critical role in both spontaneous and carcinogen-induced tumor development. This study thus reveals the important role of an innate immune signaling pathway in intestinal tumorigenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rakoff-Nahoum, Seth -- Medzhitov, Ruslan -- New York, N.Y. -- Science. 2007 Jul 6;317(5834):124-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Immunobiology, Yale University School of Medicine, New Haven, CT 06510, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17615359" target="_blank"〉PubMed〈/a〉

    Beschreibung: Significant fractions of eukaryotic genomes give rise to RNA, much of which is unannotated and has reduced protein-coding potential. The genomic origins and the associations of human nuclear and cytosolic polyadenylated RNAs longer than 200 nucleotides (nt) and whole-cell RNAs less than 200 nt were investigated in this genome-wide study. Subcellular addresses for nucleotides present in detected RNAs were assigned, and their potential processing into short RNAs was investigated. Taken together, these observations suggest a novel role for some unannotated RNAs as primary transcripts for the production of short RNAs. Three potentially functional classes of RNAs have been identified, two of which are syntenically conserved and correlate with the expression state of protein-coding genes. These data support a highly interleaved organization of the human transcriptome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kapranov, Philipp -- Cheng, Jill -- Dike, Sujit -- Nix, David A -- Duttagupta, Radharani -- Willingham, Aarron T -- Stadler, Peter F -- Hertel, Jana -- Hackermuller, Jorg -- Hofacker, Ivo L -- Bell, Ian -- Cheung, Evelyn -- Drenkow, Jorg -- Dumais, Erica -- Patel, Sandeep -- Helt, Gregg -- Ganesh, Madhavan -- Ghosh, Srinka -- Piccolboni, Antonio -- Sementchenko, Victor -- Tammana, Hari -- Gingeras, Thomas R -- N01-CO-12400/CO/NCI NIH HHS/ -- U01HG003147/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2007 Jun 8;316(5830):1484-8.

    Beschreibung: We found that, in the mouse visual cortex, action potentials generated in a single layer-2/3 pyramidal (excitatory) neuron can reliably evoke large, constant-latency inhibitory postsynaptic currents in other nearby pyramidal cells. This effect is mediated by axo-axonic ionotropic glutamate receptor-mediated excitation of the nerve terminals of inhibitory interneurons, which connect to the target pyramidal cells. Therefore, individual cortical excitatory neurons can generate inhibition independently from the somatic firing of inhibitory interneurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ren, Ming -- Yoshimura, Yumiko -- Takada, Naoki -- Horibe, Shoko -- Komatsu, Yukio -- New York, N.Y. -- Science. 2007 May 4;316(5825):758-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Research Institute of Environmental Medicine, Nagoya University, Nagoya 464-8601, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17478724" target="_blank"〉PubMed〈/a〉

    Beschreibung: Grid cells in layer II of rat entorhinal cortex fire to spatial locations in a repeating hexagonal grid, with smaller spacing between grid fields for neurons in more dorsal anatomical locations. Data from in vitro whole-cell patch recordings showed differences in frequency of subthreshold membrane potential oscillations in entorhinal neurons that correspond to different positions along the dorsal-to-ventral axis, supporting a model of physiological mechanisms for grid cell responses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2950607/" 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/PMC2950607/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giocomo, Lisa M -- Zilli, Eric A -- Fransen, Erik -- Hasselmo, Michael E -- DA16454/DA/NIDA NIH HHS/ -- MH60013/MH/NIMH NIH HHS/ -- MH71702/MH/NIMH NIH HHS/ -- P50 MH071702/MH/NIMH NIH HHS/ -- P50 MH071702-01A20004/MH/NIMH NIH HHS/ -- R01 DA016454/DA/NIDA NIH HHS/ -- R01 DA016454-04/DA/NIDA NIH HHS/ -- R01 DA016454-05/DA/NIDA NIH HHS/ -- R01 MH060013/MH/NIMH NIH HHS/ -- R01 MH060013-05/MH/NIMH NIH HHS/ -- R01 MH060013-06/MH/NIMH NIH HHS/ -- R01 MH061492/MH/NIMH NIH HHS/ -- R01 MH061492-05/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2007 Mar 23;315(5819):1719-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Memory and Brain, Department of Psychology, Program in Neuroscience, Boston University, 2 Cummington Street, Boston, MA 02215, USA. giocomo@bu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17379810" target="_blank"〉PubMed〈/a〉

    Beschreibung: Monoallelic expression with random choice between the maternal and paternal alleles defines an unusual class of genes comprising X-inactivated genes and a few autosomal gene families. Using a genome-wide approach, we assessed allele-specific transcription of about 4000 human genes in clonal cell lines and found that more than 300 were subject to random monoallelic expression. For a majority of monoallelic genes, we also observed some clonal lines displaying biallelic expression. Clonal cell lines reflect an independent choice to express the maternal, the paternal, or both alleles for each of these genes. This can lead to differences in expressed protein sequence and to differences in levels of gene expression. Unexpectedly widespread monoallelic expression suggests a mechanism that generates diversity in individual cells and their clonal descendants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gimelbrant, Alexander -- Hutchinson, John N -- Thompson, Benjamin R -- Chess, Andrew -- New York, N.Y. -- Science. 2007 Nov 16;318(5853):1136-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Human Genetic Research and Department of Medicine, Massachusetts General Hospital, Harvard Medical School, Simches Research Building, 185 Cambridge Street, Boston, MA 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18006746" target="_blank"〉PubMed〈/a〉

    Beschreibung: Humans normally experience the conscious self as localized within their bodily borders. This spatial unity may break down in certain neurological conditions such as out-of-body experiences, leading to a striking disturbance of bodily self-consciousness. On the basis of these clinical data, we designed an experiment that uses conflicting visual-somatosensory input in virtual reality to disrupt the spatial unity between the self and the body. We found that during multisensory conflict, participants felt as if a virtual body seen in front of them was their own body and mislocalized themselves toward the virtual body, to a position outside their bodily borders. Our results indicate that spatial unity and bodily self-consciousness can be studied experimentally and are based on multisensory and cognitive processing of bodily information.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lenggenhager, Bigna -- Tadi, Tej -- Metzinger, Thomas -- Blanke, Olaf -- New York, N.Y. -- Science. 2007 Aug 24;317(5841):1096-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cognitive Neuroscience, Ecole Polytechnique Federale de Lausanne, Station 15, 1015 Lausanne, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17717189" target="_blank"〉PubMed〈/a〉
