    Beschreibung: Human beings routinely help others to achieve their goals, even when the helper receives no immediate benefit and the person helped is a stranger. Such altruistic behaviors (toward non-kin) are extremely rare evolutionarily, with some theorists even proposing that they are uniquely human. Here we show that human children as young as 18 months of age (prelinguistic or just-linguistic) quite readily help others to achieve their goals in a variety of different situations. This requires both an understanding of others' goals and an altruistic motivation to help. In addition, we demonstrate similar though less robust skills and motivations in three young chimpanzees.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warneken, Felix -- Tomasello, Michael -- New York, N.Y. -- Science. 2006 Mar 3;311(5765):1301-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental and Comparative Psychology, Max Planck Institute for Evolutionary Anthropology, Deutscher Platz 6, 04103 Leipzig, Germany. warneken@eva.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16513986" target="_blank"〉PubMed〈/a〉

    Beschreibung: CD8-positive T lymphocytes recognize peptides that are usually derived from the degradation of cellular proteins and are presented by class I molecules of the major histocompatibility complex. Here we describe a human minor histocompatibility antigen created by a polymorphism in the SP110 nuclear phosphoprotein gene. The antigenic peptide comprises two noncontiguous SP110 peptide segments spliced together in reverse order to that in which they occur in the predicted SP110 protein. The antigenic peptide could be produced in vitro by incubation of precursor peptides with highly purified 20S proteasomes. Cutting and splicing probably occur within the proteasome by transpeptidation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Edus H -- Vigneron, Nathalie J -- Gavin, Marc A -- Coulie, Pierre G -- Stroobant, Vincent -- Dalet, Alexandre -- Tykodi, Scott S -- Xuereb, Suzanne M -- Mito, Jeffrey K -- Riddell, Stanley R -- Van den Eynde, Benoit J -- CA106512/CA/NCI NIH HHS/ -- CA18029/CA/NCI NIH HHS/ -- P01 CA018029/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 8;313(5792):1444-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Immunology, Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16960008" target="_blank"〉PubMed〈/a〉

    Beschreibung: Small noncoding RNAs regulate processes essential for cell growth and development, including mRNA degradation, translational repression, and transcriptional gene silencing (TGS). During a search for candidate mammalian factors for TGS, we purified a complex that contains small RNAs and Riwi, the rat homolog to human Piwi. The RNAs, frequently 29 to 30 nucleotides in length, are called Piwi-interacting RNAs (piRNAs), 94% of which map to 100 defined (〈 or = 101 kb) genomic regions. Within these regions, the piRNAs generally distribute across only one genomic strand or distribute on two strands but in a divergent, nonoverlapping manner. Preparations of piRNA complex (piRC) contain rRecQ1, which is homologous to qde-3 from Neurospora, a gene implicated in silencing pathways. Piwi has been genetically linked to TGS in flies, and slicer activity cofractionates with the purified complex. These results are consistent with a gene-silencing role for piRC in mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lau, Nelson C -- Seto, Anita G -- Kim, Jinkuk -- Kuramochi-Miyagawa, Satomi -- Nakano, Toru -- Bartel, David P -- Kingston, Robert E -- New York, N.Y. -- Science. 2006 Jul 21;313(5785):363-7.

    Beschreibung: How does the bilingual brain distinguish and control which language is in use? Previous functional imaging experiments have not been able to answer this question because proficient bilinguals activate the same brain regions irrespective of the language being tested. Here, we reveal that neuronal responses within the left caudate are sensitive to changes in the language or the meaning of words. By demonstrating this effect in populations of German-English and Japanese-English bilinguals, we suggest that the left caudate plays a universal role in monitoring and controlling the language in use.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crinion, J -- Turner, R -- Grogan, A -- Hanakawa, T -- Noppeney, U -- Devlin, J T -- Aso, T -- Urayama, S -- Fukuyama, H -- Stockton, K -- Usui, K -- Green, D W -- Price, C J -- 051067/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Jun 9;312(5779):1537-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Department of Imaging Neuroscience, University College London, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16763154" target="_blank"〉PubMed〈/a〉

    Beschreibung: Efforts to test sex ratio theory have focused mostly on females. However, when males possess traits that could enhance the reproductive success of sons, males would also benefit from the manipulation of the offspring sex ratio. We tested the prediction that more-fertile red deer males produce more sons. Our findings reveal that male fertility is positively related to the proportion of male offspring. We also show that there is a positive correlation between the percentage of morphologically normal spermatozoa (a main determinant of male fertility) and the proportion of male offspring. Thus, males may contribute significantly to biases in sex ratio at birth among mammals, creating the potential for conflicts of interest between males and females.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gomendio, Montserrat -- Malo, Aurelio F -- Soler, Ana J -- Fernandez-Santos, Maria R -- Esteso, Milagros C -- Garcia, Andres J -- Roldan, Eduardo R S -- Garde, Julian -- New York, N.Y. -- Science. 2006 Dec 1;314(5804):1445-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Reproductive Ecology and Biology Group, Department of Evolutionary Ecology, Museo Nacional de Ciencias Naturales [Consejo Superior de Investigaciones Cientificas (CSIC)], 28006-Madrid, Spain. montseg@mncn.csic.es〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17138900" target="_blank"〉PubMed〈/a〉

    Beschreibung: According to theory, homoploid hybrid speciation, which is hybrid speciation without a change in chromosome number, is facilitated by adaptation to a novel or extreme habitat. Using molecular and ecological data, we found that the alpine-adapted butterflies in the genus Lycaeides are the product of hybrid speciation. The alpine populations possess a mosaic genome derived from both L. melissa and L. idas and are differentiated from and younger than their putative parental species. As predicted, adaptive traits may allow for persistence in the environmentally extreme alpine habitat and reproductively isolate these populations from their parental species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gompert, Zachariah -- Fordyce, James A -- Forister, Matthew L -- Shapiro, Arthur M -- Nice, Chris C -- New York, N.Y. -- Science. 2006 Dec 22;314(5807):1923-5.

    Beschreibung: During embryogenesis, stem cells are set aside to fuel the postnatal hair cycle and repair the epidermis after injury. To define how hair follicle stem cells are specified and maintained in an undifferentiated state, we developed a strategy to isolate and transcriptionally profile embryonic hair progenitors in mice. We identified Lhx2 as a transcription factor positioned downstream of signals necessary to specify hair follicle stem cells, but upstream from signals required to drive activated stem cells to terminally differentiate. Using gain- and loss-of-function studies, we uncovered a role for Lhx2 in maintaining the growth and undifferentiated properties of hair follicle progenitors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2405918/" 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/PMC2405918/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rhee, Horace -- Polak, Lisa -- Fuchs, Elaine -- R01 AR031737/AR/NIAMS NIH HHS/ -- R01 AR031737-24/AR/NIAMS NIH HHS/ -- R01 AR050452/AR/NIAMS NIH HHS/ -- R01 AR050452-04/AR/NIAMS NIH HHS/ -- R01-AR050452/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Jun 30;312(5782):1946-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Rockefeller University, 1230 York Avenue, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16809539" target="_blank"〉PubMed〈/a〉

We have since obtained a specimen killed by a farmer on Mount Rungwe, the type locality. Detailed molecular phylogenetic analyses of this specimen demonstrate that the genus Lophocebus is diphyletic. We provide a description of a new genus of African monkey and of the only preserved specimen of this primate.

    Beschreibung: The Dobzhansky-Muller model proposes that hybrid incompatibilities are caused by the interaction between genes that have functionally diverged in the respective hybridizing species. Here, we show that Lethal hybrid rescue (Lhr) has functionally diverged in Drosophila simulans and interacts with Hybrid male rescue (Hmr), which has functionally diverged in D. melanogaster, to cause lethality in F1 hybrid males. LHR localizes to heterochromatic regions of the genome and has diverged extensively in sequence between these species in a manner consistent with positive selection. Rapidly evolving heterochromatic DNA sequences may be driving the evolution of this incompatibility gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brideau, Nicholas J -- Flores, Heather A -- Wang, Jun -- Maheshwari, Shamoni -- Wang, Xu -- Barbash, Daniel A -- R01 GM074737-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 24;314(5803):1292-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Genetics, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17124320" target="_blank"〉PubMed〈/a〉

    Beschreibung: The liver can regenerate its volume after major tissue loss. In a mouse model of liver regeneration, thrombocytopenia, or impaired platelet activity resulted in the failure to initiate cellular proliferation in the liver. Platelets are major carriers of serotonin in the blood. In thrombocytopenic mice, a serotonin agonist reconstituted liver proliferation. The expression of 5-HT2A and 2B subtype serotonin receptors in the liver increased after hepatectomy. Antagonists of 5-HT2A and 2B receptors inhibited liver regeneration. Liver regeneration was also blunted in mice lacking tryptophan hydroxylase 1, which is the rate-limiting enzyme for the synthesis of peripheral serotonin.

    Beschreibung: Translocation is one of the most frequently occurring human chromosomal aberrations. The constitutional t(11;22)(q23;q11), which is the only known recurrent non-Robertsonian translocation, represents a good model for studying translocations in humans. Here we demonstrate polymorphisms of the palindromic sequence at the t(11;22) breakpoint that affect the frequency of de novo translocations in sperm from normal males. A typical allele consists of a perfect palindrome, producing ~10-5 de novo t(11;22) translocations. Alleles with an asymmetric center do not form the t(11;22). Our data show the importance of genome sequence on chromosomal rearrangements, a class of human mutation that is thought to be random.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2818512/" 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/PMC2818512/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kato, Takema -- Inagaki, Hidehito -- Yamada, Kouji -- Kogo, Hiroshi -- Ohye, Tamae -- Kowa, Hiroe -- Nagaoka, Kayuri -- Taniguchi, Mariko -- Emanuel, Beverly S -- Kurahashi, Hiroki -- CA39926/CA/NCI NIH HHS/ -- P01 DC002027/DC/NIDCD NIH HHS/ -- P01 DC002027-070006/DC/NIDCD NIH HHS/ -- R01 CA039926/CA/NCI NIH HHS/ -- R01 CA039926-18/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):971.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Genetics, Institute for Comprehensive Medical Science, Fujita Health University, 1-98 Dengakugakubo, Kutsukake-cho, Toyoake Aichi 470-1192, Japan [corrected]〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484486" target="_blank"〉PubMed〈/a〉

    Beschreibung: Few sub-Saharan African countries have witnessed declines in HIV prevalence, and only Uganda has compelling evidence for a decline founded on sexual behavior change. We report a decline in HIV prevalence in eastern Zimbabwe between 1998 and 2003 associated with sexual behavior change in four distinct socioeconomic strata. HIV prevalence fell most steeply at young ages-by 23 and 49%, respectively, among men aged 17 to 29 years and women aged 15 to 24 years-and in more educated groups. Sexually experienced men and women reported reductions in casual sex of 49 and 22%, respectively, whereas recent cohorts reported delayed sexual debut. Selective AIDS-induced mortality contributed to the decline in HIV prevalence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gregson, Simon -- Garnett, Geoffrey P -- Nyamukapa, Constance A -- Hallett, Timothy B -- Lewis, James J C -- Mason, Peter R -- Chandiwana, Stephen K -- Anderson, Roy M -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Feb 3;311(5761):664-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Infectious Disease Epidemiology, Imperial College London, UK.

    Beschreibung: The molecular mechanisms controlling human hair growth and scalp hair loss are poorly understood. By screening about 350,000 individuals in two populations from the Volga-Ural region of Russia, we identified a gene mutation in families who show an inherited form of hair loss and a hair growth defect. Affected individuals were homozygous for a deletion in the LIPH gene on chromosome 3q27, caused by short interspersed nuclear element-retrotransposon-mediated recombination. The LIPH gene is expressed in hair follicles and encodes a phospholipase called lipase H (alternatively known as membrane-associated phosphatidic acid-selective phospholipase A1alpha), an enzyme that regulates the production of bioactive lipids. These results suggest that lipase H participates in hair growth and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kazantseva, Anastasiya -- Goltsov, Andrey -- Zinchenko, Rena -- Grigorenko, Anastasia P -- Abrukova, Anna V -- Moliaka, Yuri K -- Kirillov, Alexander G -- Guo, Zhiru -- Lyle, Stephen -- Ginter, Evgeny K -- Rogaev, Evgeny I -- K08-AR02179/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 10;314(5801):982-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brudnick Neuropsychiatric Research Institute, Department of Psychiatry, University of Massachusetts Medical School, 303 Belmont Street, Worcester, MA 01604, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17095700" target="_blank"〉PubMed〈/a〉

    Beschreibung: Eukaryotic flagella and cilia are built on a 9 + 2 array of microtubules plus 〉250 accessory proteins, forming a biological machine called the axoneme. Here we describe the three-dimensional structure of rapidly frozen axonemes from Chlamydomonas and sea urchin sperm, using cryoelectron tomography and image processing to focus on the motor enzyme dynein. Our images suggest a model for the way dynein generates force to slide microtubules. They also reveal two dynein linkers that may provide "hard-wiring" to coordinate motor enzyme action, both circumferentially and along the axoneme. Periodic densities were also observed inside doublet microtubules; these may contribute to doublet stability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nicastro, Daniela -- Schwartz, Cindi -- Pierson, Jason -- Gaudette, Richard -- Porter, Mary E -- McIntosh, J Richard -- 2R37-GM55667/GM/NIGMS NIH HHS/ -- RR 000592/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2006 Aug 18;313(5789):944-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for 3D Electron Microscopy of Cells, Department of Molecular, Cellular, and Developmental Biology, CB 347, University of Colorado, Boulder, CO 80309-0347, USA. nicastro@colorado.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16917055" target="_blank"〉PubMed〈/a〉

    Beschreibung: Age-related macular degeneration (AMD), the most common cause of irreversible vision loss in individuals aged older than 50 years, is classified as either wet (neovascular) or dry (nonneovascular). Inherited variation in the complement factor H gene is a major risk factor for drusen in dry AMD. Here we report that a single-nucleotide polymorphism in the promoter region of HTRA1, a serine protease gene on chromosome 10q26, is a major genetic risk factor for wet AMD. A whole-genome association mapping strategy was applied to a Chinese population, yielding a P value of 〈10(-11). Individuals with the risk-associated genotype were estimated to have a likelihood of developing wet AMD 10 times that of individuals with the wild-type genotype.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dewan, Andrew -- Liu, Mugen -- Hartman, Stephen -- Zhang, Samuel Shao-Min -- Liu, David T L -- Zhao, Connie -- Tam, Pancy O S -- Chan, Wai Man -- Lam, Dennis S C -- Snyder, Michael -- Barnstable, Colin -- Pang, Chi Pui -- Hoh, Josephine -- New York, N.Y. -- Science. 2006 Nov 10;314(5801):989-92.

    Beschreibung: Mounting evidence has revealed pathological interactions between HIV and malaria in dually infected patients, but the public health implications of the interplay have remained unclear. A transient almost one-log elevation in HIV viral load occurs during febrile malaria episodes; in addition, susceptibility to malaria is enhanced in HIV-infected patients. A mathematical model applied to a setting in Kenya with an adult population of roughly 200,000 estimated that, since 1980, the disease interaction may have been responsible for 8,500 excess HIV infections and 980,000 excess malaria episodes. Co-infection might also have facilitated the geographic expansion of malaria in areas where HIV prevalence is high. Hence, transient and repeated increases in HIV viral load resulting from recurrent co-infection with malaria may be an important factor in promoting the spread of HIV in sub-Saharan Africa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abu-Raddad, Laith J -- Patnaik, Padmaja -- Kublin, James G -- P30 AI 27757/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1603-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Statistical Center for HIV/AIDS Research and Prevention, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA. laith@scharp.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158329" target="_blank"〉PubMed〈/a〉

    Beschreibung: Fat tissue is the most important energy depot in vertebrates. The release of free fatty acids (FFAs) from stored fat requires the enzymatic activity of lipases. We showed that genetic inactivation of adipose triglyceride lipase (ATGL) in mice increases adipose mass and leads to triacylglycerol deposition in multiple tissues. ATGL-deficient mice accumulated large amounts of lipid in the heart, causing cardiac dysfunction and premature death. Defective cold adaptation indicated that the enzyme provides FFAs to fuel thermogenesis. The reduced availability of ATGL-derived FFAs leads to increased glucose use, increased glucose tolerance, and increased insulin sensitivity. These results indicate that ATGL is rate limiting in the catabolism of cellular fat depots and plays an important role in energy homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haemmerle, Guenter -- Lass, Achim -- Zimmermann, Robert -- Gorkiewicz, Gregor -- Meyer, Carola -- Rozman, Jan -- Heldmaier, Gerhard -- Maier, Robert -- Theussl, Christian -- Eder, Sandra -- Kratky, Dagmar -- Wagner, Erwin F -- Klingenspor, Martin -- Hoefler, Gerald -- Zechner, Rudolf -- F 3001/Austrian Science Fund FWF/Austria -- F 3002/Austrian Science Fund FWF/Austria -- New York, N.Y. -- Science. 2006 May 5;312(5774):734-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular Biosciences, University of Graz, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16675698" target="_blank"〉PubMed〈/a〉

    Beschreibung: Our knowledge of Neanderthals is based on a limited number of remains and artifacts from which we must make inferences about their biology, behavior, and relationship to ourselves. Here, we describe the characterization of these extinct hominids from a new perspective, based on the development of a Neanderthal metagenomic library and its high-throughput sequencing and analysis. Several lines of evidence indicate that the 65,250 base pairs of hominid sequence so far identified in the library are of Neanderthal origin, the strongest being the ascertainment of sequence identities between Neanderthal and chimpanzee at sites where the human genomic sequence is different. These results enabled us to calculate the human-Neanderthal divergence time based on multiple randomly distributed autosomal loci. Our analyses suggest that on average the Neanderthal genomic sequence we obtained and the reference human genome sequence share a most recent common ancestor approximately 706,000 years ago, and that the human and Neanderthal ancestral populations split approximately 370,000 years ago, before the emergence of anatomically modern humans. Our finding that the Neanderthal and human genomes are at least 99.5% identical led us to develop and successfully implement a targeted method for recovering specific ancient DNA sequences from metagenomic libraries. This initial analysis of the Neanderthal genome advances our understanding of the evolutionary relationship of Homo sapiens and Homo neanderthalensis and signifies the dawn of Neanderthal genomics.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2583069/" 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/PMC2583069/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noonan, James P -- Coop, Graham -- Kudaravalli, Sridhar -- Smith, Doug -- Krause, Johannes -- Alessi, Joe -- Chen, Feng -- Platt, Darren -- Paabo, Svante -- Pritchard, Jonathan K -- Rubin, Edward M -- 1-F32-GM074367/GM/NIGMS NIH HHS/ -- HL066681/HL/NHLBI NIH HHS/ -- R01 HG002772/HG/NHGRI NIH HHS/ -- R01 HG002772-01/HG/NHGRI NIH HHS/ -- R01 HG002772-1/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 17;314(5802):1113-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉U.S. Department of Energy Joint Genome Institute, 2800 Mitchell Drive, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17110569" target="_blank"〉PubMed〈/a〉

    Beschreibung: Theories about sexual selection can be traced back to Darwin in 1871. He proposed that males fertilize as many females as possible with inexpensive sperm, whereas females, with a limited supply of large eggs, select the genetically highest quality males to endow their offspring with superior capabilities. Since its proposal, problems with this narrative have continued to accumulate, and it is our view that sexual selection theory needs to be replaced. We suggest an approach that relies on the exchange of direct ecological benefits among cooperating animals without reference to genetic benefits. This approach can be expressed mathematically in a branch of game theory that pertains to bargaining and side payments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roughgarden, Joan -- Oishi, Meeko -- Akcay, Erol -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):965-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Stanford University, Stanford, CA 94305-5020, USA. joan.roughgarden@stanford.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484485" target="_blank"〉PubMed〈/a〉

    Beschreibung: Cognitive functions dependent on the prefrontal cortex, such as the ability to suppress behavior (response inhibition) and to learn from complex feedback (probabilistic learning), play critical roles in activities of daily life. To what extent do different neurochemical systems modulate these two cognitive functions? Here, using stop-signal and probabilistic learning tasks, we show a double dissociation for the involvement of noradrenaline and serotonin in human cognition. In healthy volunteers, inhibition of central noradrenaline reuptake improved response inhibition but had no effect on probabilistic learning, whereas inhibition of central serotonin reuptake impaired probabilistic learning with no effect on response inhibition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1867315/" 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/PMC1867315/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chamberlain, Samuel R -- Muller, Ulrich -- Blackwell, Andrew D -- Clark, Luke -- Robbins, Trevor W -- Sahakian, Barbara J -- 076274/Wellcome Trust/United Kingdom -- G0001354/Medical Research Council/United Kingdom -- G0401099/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):861-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of Cambridge School of Clinical Medicine, Addenbrooke's Hospital, Box 189, Cambridge CB2 2QQ, UK. src33@cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469930" target="_blank"〉PubMed〈/a〉

    Beschreibung: The pathophysiology of depression remains enigmatic, although abnormalities in serotonin signaling have been implicated. We have found that the serotonin 1B receptor [5-hydroxytryptamine (5-HT1B) receptor] interacts with p11. p11 increases localization of 5-HT1B receptors at the cell surface. p11 is increased in rodent brains by antidepressants or electroconvulsive therapy, but decreased in an animal model of depression and in brain tissue from depressed patients. Overexpression of p11 increases 5-HT1B receptor function in cells and recapitulates certain behaviors seen after antidepressant treatment in mice. p11 knockout mice exhibit a depression-like phenotype and have reduced responsiveness to 5-HT1B receptor agonists and reduced behavioral reactions to an antidepressant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Svenningsson, Per -- Chergui, Karima -- Rachleff, Ilan -- Flajolet, Marc -- Zhang, Xiaoqun -- El Yacoubi, Malika -- Vaugeois, Jean-Marie -- Nomikos, George G -- Greengard, Paul -- DA10044/DA/NIDA NIH HHS/ -- MH40899/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):77-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular and Cellular Neuroscience, Rockefeller University, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400147" target="_blank"〉PubMed〈/a〉

    Beschreibung: Grid cells in the medial entorhinal cortex (MEC) are part of an environment-independent spatial coordinate system. To determine how information about location, direction, and distance is integrated in the grid-cell network, we recorded from each principal cell layer of MEC in rats that explored two-dimensional environments. Whereas layer II was predominated by grid cells, grid cells colocalized with head-direction cells and conjunctive grid x head-direction cells in the deeper layers. All cell types were modulated by running speed. The conjunction of positional, directional, and translational information in a single MEC cell type may enable grid coordinates to be updated during self-motion-based navigation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sargolini, Francesca -- Fyhn, Marianne -- Hafting, Torkel -- McNaughton, Bruce L -- Witter, Menno P -- Moser, May-Britt -- Moser, Edvard I -- New York, N.Y. -- Science. 2006 May 5;312(5774):758-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for the Biology of Memory, Norwegian University of Science and Technology, 7489 Trondheim, Norway.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16675704" target="_blank"〉PubMed〈/a〉

    Beschreibung: Obesity is a heritable trait and a risk factor for many common diseases such as type 2 diabetes, heart disease, and hypertension. We used a dense whole-genome scan of DNA samples from the Framingham Heart Study participants to identify a common genetic variant near the INSIG2 gene associated with obesity. We have replicated the finding in four separate samples composed of individuals of Western European ancestry, African Americans, and children. The obesity-predisposing genotype is present in 10% of individuals. Our study suggests that common genetic polymorphisms are important determinants of obesity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herbert, Alan -- Gerry, Norman P -- McQueen, Matthew B -- Heid, Iris M -- Pfeufer, Arne -- Illig, Thomas -- Wichmann, H-Erich -- Meitinger, Thomas -- Hunter, David -- Hu, Frank B -- Colditz, Graham -- Hinney, Anke -- Hebebrand, Johannes -- Koberwitz, Kerstin -- Zhu, Xiaofeng -- Cooper, Richard -- Ardlie, Kristin -- Lyon, Helen -- Hirschhorn, Joel N -- Laird, Nan M -- Lenburg, Marc E -- Lange, Christoph -- Christman, Michael F -- CA87969/CA/NCI NIH HHS/ -- K23DK067288/DK/NIDDK NIH HHS/ -- P30DK46200/DK/NIDDK NIH HHS/ -- R01 HD060726/HD/NICHD NIH HHS/ -- R01GM046877/GM/NIGMS NIH HHS/ -- R01HL074166/HL/NHLBI NIH HHS/ -- R01HL54485/HL/NHLBI NIH HHS/ -- R01HL66289/HL/NHLBI NIH HHS/ -- R01MH59532/MH/NIMH NIH HHS/ -- U01HL65899/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 14;312(5771):279-83.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics and Genomics, Boston University Medical School, E613, 715 Albany Street, Boston, MA 02118, USA. aherbert@bu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16614226" target="_blank"〉PubMed〈/a〉

    Beschreibung: The aging of organisms is characterized by a gradual functional decline of all organ systems. Mammalian somatic cells in culture display a limited proliferative life span, at the end of which they undergo an irreversible cell cycle arrest known as replicative senescence. Whether cellular senescence contributes to organismal aging has been controversial. We investigated telomere dysfunction, a recently discovered biomarker of cellular senescence, and found that the number of senescent fibroblasts increases exponentially in the skin of aging baboons, reaching 〉15% of all cells in very old individuals. In addition, the same cells contain activated ataxia-telangiectasia mutated kinase and heterochromatinized nuclei, confirming their senescent status.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herbig, Utz -- Ferreira, Mark -- Condel, Laura -- Carey, Dee -- Sedivy, John M -- F32 CA099388/CA/NCI NIH HHS/ -- P01 HL028972/HL/NHLBI NIH HHS/ -- P20 RR015578/RR/NCRR NIH HHS/ -- P51 RR013986/RR/NCRR NIH HHS/ -- R01 AG016694/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2006 Mar 3;311(5765):1257.

    Beschreibung: The Xist noncoding RNA is the key initiator of the process of X chromosome inactivation in eutherian mammals, but its precise function and origin remain unknown. Although Xist is well conserved among eutherians, until now, no homolog has been identified in other mammals. We show here that Xist evolved, at least partly, from a protein-coding gene and that the loss of protein-coding function of the proto-Xist coincides with the four flanking protein genes becoming pseudogenes. This event occurred after the divergence between eutherians and marsupials, which suggests that mechanisms of dosage compensation have evolved independently in both lineages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duret, Laurent -- Chureau, Corinne -- Samain, Sylvie -- Weissenbach, Jean -- Avner, Philip -- New York, N.Y. -- Science. 2006 Jun 16;312(5780):1653-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Biometrie et Biologie Evolutive (UMR 5558), CNRS and Universite Lyon 1, 16 rue Raphael Dubois, 69622 Villeurbanne Cedex, France. duret@biomserv.univ-lyon1.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16778056" target="_blank"〉PubMed〈/a〉

    Beschreibung: Weta are giant, flightless grasshoppers that are endemic to New Zealand. In the absence of native mammals, weta are thought to perform similar ecological functions. As such, they might be expected to be important seeds dispersers. However, insects are not known to consume fleshy fruits and to disperse seeds after gut passage. We conducted a series of observations and experiments to test whether weta form mutualistic partnerships with fleshy-fruited plants as seed dispersers, similar to small mammals elsewhere in the world. Results showed that weta are indeed effective seeds dispersers, providing an example of ecological convergence between unrelated organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duthie, Catherine -- Gibbs, George -- Burns, K C -- New York, N.Y. -- Science. 2006 Mar 17;311(5767):1575.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, Victoria University of Wellington, Post Office Box 600, Wellington, New Zealand.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16543452" target="_blank"〉PubMed〈/a〉

    Beschreibung: We describe reproductive isolation caused by a gene transposition. In certain Drosophila melanogaster-D. simulans hybrids, hybrid male sterility is caused by the lack of a single-copy gene essential for male fertility, JYAlpha. This gene is located on the fourth chromosome of D. melanogaster but on the third chromosome of D. simulans. Genomic and molecular analyses show that JYAlpha transposed to the third chromosome during the evolutionary history of the D. simulans lineage. Because of this transposition, a fraction of hybrids completely lack JYAlpha and are sterile, representing reproductive isolation without sequence evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masly, John P -- Jones, Corbin D -- Noor, Mohamed A F -- Locke, John -- Orr, H Allen -- New York, N.Y. -- Science. 2006 Sep 8;313(5792):1448-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Rochester, Rochester, NY 14627, USA. msly@mail.rochester.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16960009" target="_blank"〉PubMed〈/a〉

    Beschreibung: Face perception is a skill crucial to primates. In both humans and macaque monkeys, functional magnetic resonance imaging (fMRI) reveals a system of cortical regions that show increased blood flow when the subject views images of faces, compared with images of objects. However, the stimulus selectivity of single neurons within these fMRI-identified regions has not been studied. We used fMRI to identify and target the largest face-selective region in two macaques for single-unit recording. Almost all (97%) of the visually responsive neurons in this region were strongly face selective, indicating that a dedicated cortical area exists to support face processing in the macaque.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2678572/" 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/PMC2678572/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsao, Doris Y -- Freiwald, Winrich A -- Tootell, Roger B H -- Livingstone, Margaret S -- EY13025/EY/NEI NIH HHS/ -- EY13135/EY/NEI NIH HHS/ -- P41:RR14075/RR/NCRR NIH HHS/ -- R01 EY016187/EY/NEI NIH HHS/ -- R01 EY016187-01A2/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 3;311(5761):670-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Harvard Medical School, Boston, MA 02115, USA. doris@nmr.mgh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16456083" target="_blank"〉PubMed〈/a〉

    Beschreibung: Theory predicts that linkage between genetic loci reduces the efficiency of purifying selection. Because of the permanent linkage of all heritable genetic material, asexual lineages may be exceptionally prone to deleterious-mutation accumulation in both nuclear and organelle genes. Here, we show that the ratio of the rate of amino acid to silent substitution (Ka/Ks) in mitochondrial protein-coding genes is higher in obligately asexual lineages than in sexual lineages of the microcrustacean Daphnia pulex. Using a phylogeny-based approach to quantify the frequency of mutational-effect classes, we estimate that mitochondrial protein-coding genes in asexual lineages accumulate deleterious amino acid substitutions at four times the rate in sexual lineages. These results support the hypothesis that sexual reproduction plays a prominent role in reducing the mutational burden in populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paland, Susanne -- Lynch, Michael -- GM36827/GM/NIGMS NIH HHS/ -- R01 GM036827/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):990-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Indiana University, 1001 East 3rd Street, Bloomington, IN 47405, USA. spaland@indiana.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484491" target="_blank"〉PubMed〈/a〉

    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: Liver regeneration is an orchestrated cellular response that coordinates cell activation, lipid metabolism, and cell division. We found that caveolin-1 gene-disrupted mice (cav1-/- mice) exhibited impaired liver regeneration and low survival after a partial hepatectomy. Hepatocytes showed dramatically reduced lipid droplet accumulation and did not advance through the cell division cycle. Treatment of cav1-/- mice with glucose (which is a predominant energy substrate when compared to lipids) drastically increased survival and reestablished progression of the cell cycle. Thus, caveolin-1 plays a crucial role in the mechanisms that coordinate lipid metabolism with the proliferative response occurring in the liver after cellular injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fernandez, Manuel A -- Albor, Cecilia -- Ingelmo-Torres, Mercedes -- Nixon, Susan J -- Ferguson, Charles -- Kurzchalia, Teymuras -- Tebar, Francesc -- Enrich, Carlos -- Parton, Robert G -- Pol, Albert -- New York, N.Y. -- Science. 2006 Sep 15;313(5793):1628-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departament de Biologia Cellular, Facultat de Medicina, Institut d'Investigacions Biomediques August Pi i Sunyer, Universitat de Barcelona, Casanova 143, 08036 Barcelona, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16973879" target="_blank"〉PubMed〈/a〉

    Beschreibung: Humans restrain self-interest with moral and social values. They are the only species known to exhibit reciprocal fairness, which implies the punishment of other individuals' unfair behaviors, even if it hurts the punisher's economic self-interest. Reciprocal fairness has been demonstrated in the Ultimatum Game, where players often reject their bargaining partner's unfair offers. Despite progress in recent years, however, little is known about how the human brain limits the impact of selfish motives and implements fair behavior. Here we show that disruption of the right, but not the left, dorsolateral prefrontal cortex (DLPFC) by low-frequency repetitive transcranial magnetic stimulation substantially reduces subjects' willingness to reject their partners' intentionally unfair offers, which suggests that subjects are less able to resist the economic temptation to accept these offers. Importantly, however, subjects still judge such offers as very unfair, which indicates that the right DLPFC plays a key role in the implementation of fairness-related behaviors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knoch, Daria -- Pascual-Leone, Alvaro -- Meyer, Kaspar -- Treyer, Valerie -- Fehr, Ernst -- K24 RR018875/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 3;314(5800):829-32.

    Beschreibung: Organisms ranging from bacteria to humans synchronize their internal clocks to daily cycles of light and dark. Photic entrainment of the Drosophila clock is mediated by proteasomal degradation of the clock protein TIMELESS (TIM). We have identified mutations in jetlag-a gene coding for an F-box protein with leucine-rich repeats-that result in reduced light sensitivity of the circadian clock. Mutant flies show rhythmic behavior in constant light, reduced phase shifts in response to light pulses, and reduced light-dependent degradation of TIM. Expression of JET along with the circadian photoreceptor cryptochrome (CRY) in cultured S2R cells confers light-dependent degradation onto TIM, thereby reconstituting the acute response + of the circadian clock to light in a cell culture system. Our results suggest that JET is essential for resetting the clock by transmitting light signals from CRY to TIM.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2767177/" 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/PMC2767177/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koh, Kyunghee -- Zheng, Xiangzhong -- Sehgal, Amita -- NS048471/NS/NINDS NIH HHS/ -- R01 NS048471/NS/NINDS NIH HHS/ -- R01 NS048471-02/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2006 Jun 23;312(5781):1809-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Neuroscience, University of Pennsylvania School of Medicine, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16794082" 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: The role of dopamine in monitoring negative action outcomes and feedback-based learning was tested in a neuroimaging study in humans grouped according to the dopamine D2 receptor gene polymorphism DRD2-TAQ-IA. In a probabilistic learning task, A1-allele carriers with reduced dopamine D2 receptor densities learned to avoid actions with negative consequences less efficiently. Their posterior medial frontal cortex (pMFC), involved in feedback monitoring, responded less to negative feedback than others' did. Dynamically changing interactions between pMFC and hippocampus found to underlie feedback-based learning were reduced in A1-allele carriers. This demonstrates that learning from errors requires dopaminergic signaling. Dopamine D2 receptor reduction seems to decrease sensitivity to negative action consequences, which may explain an increased risk of developing addictive behaviors in A1-allele carriers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Klein, Tilmann A -- Neumann, Jane -- Reuter, Martin -- Hennig, Jurgen -- von Cramon, D Yves -- Ullsperger, Markus -- R01MH74457/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2007 Dec 7;318(5856):1642-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig, Germany. tklein@cbs.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18063800" 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: 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: Whether social comparison affects individual well-being is of central importance for understanding behavior in any social environment. Traditional economic theories focus on the role of absolute rewards, whereas behavioral evidence suggests that social comparisons influence well-being and decisions. We investigated the impact of social comparisons on reward-related brain activity using functional magnetic resonance imaging (fMRI). While being scanned in two adjacent MRI scanners, pairs of subjects had to simultaneously perform a simple estimation task that entailed monetary rewards for correct answers. We show that a variation in the comparison subject's payment affects blood oxygenation level-dependent responses in the ventral striatum. Our results provide neurophysiological evidence for the importance of social comparison on reward processing in the human brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fliessbach, K -- Weber, B -- Trautner, P -- Dohmen, T -- Sunde, U -- Elger, C E -- Falk, A -- New York, N.Y. -- Science. 2007 Nov 23;318(5854):1305-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Life and Brain Center Bonn, Department of NeuroCognition and Clinic of Epileptology, Bonn, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18033886" 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: 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: 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〉

Despite striking cellular and genetic similarities that suggest a common evolutionary origin, however, male and female GSCs also display important differences.

    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〉

We found that the mutual influence among neuronal groups depends on the phase relation between rhythmic activities within the groups. Phase relations supporting interactions between the groups preceded those interactions by a few milliseconds, consistent with a mechanistic role. These effects were specific in time, frequency, and space, and we therefore propose that the pattern of synchronization flexibly determines the pattern of neuronal interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Womelsdorf, Thilo -- Schoffelen, Jan-Mathijs -- Oostenveld, Robert -- Singer, Wolf -- Desimone, Robert -- Engel, Andreas K -- Fries, Pascal -- R01EY017292/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2007 Jun 15;316(5831):1609-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉F.

    Beschreibung: Long-term potentiation (LTP), which approximates Hebb's postulate of associative learning, typically requires depolarization-dependent glutamate receptors of the NMDA (N-methyl-D-aspartate) subtype. However, in some neurons, LTP depends instead on calcium-permeable AMPA-type receptors. This is paradoxical because intracellular polyamines block such receptors during depolarization. We report that LTP at synapses on hippocampal interneurons mediating feedback inhibition is "anti-Hebbian":Itis induced by presynaptic activity but prevented by postsynaptic depolarization. Anti-Hebbian LTP may occur in interneurons that are silent during periods of intense pyramidal cell firing, such as sharp waves, and lead to their altered activation during theta activity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3369266/" 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/PMC3369266/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamsa, Karri P -- Heeroma, Joost H -- Somogyi, Peter -- Rusakov, Dmitri A -- Kullmann, Dimitri M -- 071179/Wellcome Trust/United Kingdom -- G0400627/Medical Research Council/United Kingdom -- G0400627(71256)/Medical Research Council/United Kingdom -- G0400627(76527)/Medical Research Council/United Kingdom -- G0501424/Medical Research Council/United Kingdom -- G0600368/Medical Research Council/United Kingdom -- G0600368(77987)/Medical Research Council/United Kingdom -- MC_U138135973/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2007 Mar 2;315(5816):1262-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Neurology, University College London, Queen Square, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17332410" 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: Adult stem cells often divide asymmetrically to produce one self-renewed stem cell and one differentiating cell, thus maintaining both populations. The asymmetric outcome of stem cell divisions can be specified by an oriented spindle and local self-renewal signals from the stem cell niche. Here we show that developmentally programmed asymmetric behavior and inheritance of mother and daughter centrosomes underlies the stereotyped spindle orientation and asymmetric outcome of stem cell divisions in the Drosophila male germ line. The mother centrosome remains anchored near the niche while the daughter centrosome migrates to the opposite side of the cell before spindle formation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2563045/" 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/PMC2563045/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamashita, Yukiko M -- Mahowald, Anthony P -- Perlin, Julie R -- Fuller, Margaret T -- P01 DK053074/DK/NIDDK NIH HHS/ -- P01 DK53074/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2007 Jan 26;315(5811):518-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental Biology, Stanford University School of Medicine, Stanford, CA 94305-5329, USA. yukikomy@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17255513" 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〉

    Beschreibung: Sjoblom et al. (Research Article, 13 October 2006, p. 268) reported nearly 200 novel cancer genes said to have a 90% probability of being involved in colon or breast cancer. However, their analysis raises two statistical concerns. When these concerns are addressed, few genes with significantly elevated mutation rates remain. Although the biological methodology in Sjoblom et al. is sound, more samples are needed to achieve sufficient power.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Getz, Gad -- Hofling, Holger -- Mesirov, Jill P -- Golub, Todd R -- Meyerson, Matthew -- Tibshirani, Robert -- Lander, Eric S -- New York, N.Y. -- Science. 2007 Sep 14;317(5844):1500.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute of Massachusetts Institute of Technology and Harvard University, Cambridge, MA 02142, USA. gadgetz@broad.mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17872428" target="_blank"〉PubMed〈/a〉

    Beschreibung: Memory processes are modulated by the biological clock, although the mechanisms are unknown. Here, we report that in the diurnal zebrafish both learning and memory formation of an operant conditioning paradigm occur better during the day than during the night. Melatonin treatment during the day mimics the nighttime suppression of memory formation. Training in constant light improves nighttime memory formation while reducing endogenous melatonin concentrations. Treatment with melatonin receptor antagonists at night dramatically improves memory. Pinealectomy also significantly improves nighttime memory formation. We adduce that melatonin is both sufficient and necessary for poor memory formation during the night.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rawashdeh, Oliver -- de Borsetti, Nancy Hernandez -- Roman, Gregg -- Cahill, Gregory M -- MH60939/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 16;318(5853):1144-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology and Biochemistry, University of Houston, 369 Science and Research II, Houston, TX 77204-5001, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18006748" target="_blank"〉PubMed〈/a〉
