    Description: Genetic exchange has not been shown to be a mechanism underlying the extensive diversity of Leishmania parasites. We report here evidence that the invertebrate stages of Leishmania are capable of having a sexual cycle consistent with a meiotic process like that described for African trypanosomes. Hybrid progeny were generated that bore full genomic complements from both parents, but kinetoplast DNA maxicircles from one parent. Mating occurred only in the sand fly vector, and hybrids were transmitted to the mammalian host by sand fly bite. Genetic exchange likely contributes to phenotypic diversity in natural populations, and analysis of hybrid progeny will be useful for positional cloning of the genes controlling traits such as virulence, tissue tropism, and drug resistance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2729066/" 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/PMC2729066/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akopyants, Natalia S -- Kimblin, Nicola -- Secundino, Nagila -- Patrick, Rachel -- Peters, Nathan -- Lawyer, Phillip -- Dobson, Deborah E -- Beverley, Stephen M -- Sacks, David L -- A1020941/PHS HHS/ -- A1029646/PHS HHS/ -- R01 AI029646/AI/NIAID NIH HHS/ -- R01 AI029646-20/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):265-8. doi: 10.1126/science.1169464.〈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/19359589" target="_blank"〉PubMed〈/a〉

    Description: Sleep deprivation can impair human health and performance. Habitual total sleep time and homeostatic sleep response to sleep deprivation are quantitative traits in humans. Genetic loci for these traits have been identified in model organisms, but none of these potential animal models have a corresponding human genotype and phenotype. We have identified a mutation in a transcriptional repressor (hDEC2-P385R) that is associated with a human short sleep phenotype. Activity profiles and sleep recordings of transgenic mice carrying this mutation showed increased vigilance time and less sleep time than control mice in a zeitgeber time- and sleep deprivation-dependent manner. These mice represent a model of human sleep homeostasis that provides an opportunity to probe the effect of sleep on human physical and mental health.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2884988/" 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/PMC2884988/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He, Ying -- Jones, Christopher R -- Fujiki, Nobuhiro -- Xu, Ying -- Guo, Bin -- Holder, Jimmy L Jr -- Rossner, Moritz J -- Nishino, Seiji -- Fu, Ying-Hui -- HL059596/HL/NHLBI NIH HHS/ -- MH074924/MH/NIMH NIH HHS/ -- R01 HL059596/HL/NHLBI NIH HHS/ -- R01 HL059596-09/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 14;325(5942):866-70. doi: 10.1126/science.1174443.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, University of California at San Francisco, Mission Bay, 1550 Fourth Street, San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19679812" target="_blank"〉PubMed〈/a〉

    Description: The pace of Late Triassic (LT) biodiversity loss is uncertain, yet it could help to decipher causal mechanisms of mass extinction. We investigated relative abundance distributions (RADs) of six LT plant assemblages from the Kap Stewart Group, East Greenland, to determine the pace of collapse of LT primary productivity. RADs displayed not simply decreases in the number of taxa, but decreases in the number of common taxa. Likelihood tests rejected a hypothesis of continuously declining diversity. Instead, the RAD shift occurred over the upper two-to-four fossil plant assemblages and most likely over the last three (final 13 meters), coinciding with increased atmospheric carbon dioxide concentration and global warming. Thus, although the LT event did not induce mass extinction of plant families, it accompanied major and abrupt change in their ecology and diversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McElwain, Jennifer C -- Wagner, Peter J -- Hesselbo, Stephen P -- New York, N.Y. -- Science. 2009 Jun 19;324(5934):1554-6. doi: 10.1126/science.1171706.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UCD School of Biology and Environmental Science, University College Dublin, National University of Ireland, Belfield, Dublin 4, Ireland. jennifer.mcelwain@ucd.ie〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19541995" target="_blank"〉PubMed〈/a〉

    Description: Ecological speciation occurs when ecologically based, divergent selection causes the evolution of reproductive isolation. There are many empirical examples of this process; however, there exists a poorly characterized stage during which the traits that distinguish species ecologically and reproductively segregate in a single population. By using a combination of genetic mapping, mate-choice experiments, field observations, and population genetics, we studied a butterfly population with a mimetic wing color polymorphism and found that the butterflies exhibited partial, color-based, assortative mate preference. These traits represent the divergent, ecologically based signal and preference components of sexual isolation that usually distinguish incipient and sibling species. The association between behavior and recognition trait in a single population may enhance the probability of speciation and provides an example of the missing link between an interbreeding population and isolated species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875868/" 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/PMC2875868/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chamberlain, Nicola L -- Hill, Ryan I -- Kapan, Durrell D -- Gilbert, Lawrence E -- Kronforst, Marcus R -- GM068763/GM/NIGMS NIH HHS/ -- P50 GM068763/GM/NIGMS NIH HHS/ -- P50 GM068763-06/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):847-50. doi: 10.1126/science.1179141.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Faculty of Arts and Sciences Center for Systems Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892982" target="_blank"〉PubMed〈/a〉

    Description: Children acquire their native language according to a well-defined time frame. Surprisingly, although children raised in bilingual environments have to learn roughly twice as much about language as their monolingual peers, the speed of acquisition is comparable in monolinguals and bilinguals. Here, we show that preverbal 12-month-old bilingual infants have become more flexible at learning speech structures than monolinguals. When given the opportunity to simultaneously learn two different regularities, bilingual infants learned both, whereas monolinguals learned only one of them. Hence, bilinguals may acquire two languages in the time in which monolinguals acquire one because they quickly become more flexible learners.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kovacs, Agnes Melinda -- Mehler, Jacques -- New York, N.Y. -- Science. 2009 Jul 31;325(5940):611-2. doi: 10.1126/science.1173947.

    Description: Throughout the history of mathematics, concepts of number and space have been tightly intertwined. We tested the hypothesis that cortical circuits for spatial attention contribute to mental arithmetic in humans. We trained a multivariate classifier algorithm to infer the direction of an eye movement, left or right, from the brain activation measured in the posterior parietal cortex. Without further training, the classifier then generalized to an arithmetic task. Its left versus right classification could be used to sort out subtraction versus addition trials, whether performed with symbols or with sets of dots. These findings are consistent with the suggestion that mental arithmetic co-opts parietal circuitry associated with spatial coding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knops, Andre -- Thirion, Bertrand -- Hubbard, Edward M -- Michel, Vincent -- Dehaene, Stanislas -- New York, N.Y. -- Science. 2009 Jun 19;324(5934):1583-5. doi: 10.1126/science.1171599.

    Description: Platelets play a critical role in the pathogenesis of malarial infections by encouraging the sequestration of infected red blood cells within the cerebral vasculature. But platelets also have well-established roles in innate protection against microbial infections. We found that purified human platelets killed Plasmodium falciparum parasites cultured in red blood cells. Inhibition of platelet function by aspirin and other platelet inhibitors abrogated the lethal effect human platelets exert on P. falciparum parasites. Likewise, platelet-deficient and aspirin-treated mice were more susceptible to death during erythrocytic infection with Plasmodium chabaudi. Both mouse and human platelets bind malarial-infected red cells and kill the parasite within. These results indicate a protective function for platelets in the early stages of erythrocytic infection distinct from their role in cerebral malaria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McMorran, Brendan J -- Marshall, Vikki M -- de Graaf, Carolyn -- Drysdale, Karen E -- Shabbar, Meriam -- Smyth, Gordon K -- Corbin, Jason E -- Alexander, Warren S -- Foote, Simon J -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):797-800. doi: 10.1126/science.1166296.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Menzies Research Institute, University of Tasmania, Private Bag 23, Hobart, Tasmania 7000, Australia. brendan.mcmorran@utas.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197068" target="_blank"〉PubMed〈/a〉

    Description: Climate change could lead to mismatches between the reproductive cycles of marine organisms and their planktonic food. We tested this hypothesis by comparing shrimp (Pandalus borealis) egg hatching times and satellite-derived phytoplankton bloom dynamics throughout the North Atlantic. At large spatial and long temporal (10 years or longer) scales, hatching was correlated with the timing of the spring phytoplankton bloom. Annual egg development and hatching times were determined locally by bottom water temperature. We conclude that different populations of P. borealis have adapted to local temperatures and bloom timing, matching egg hatching to food availability under average conditions. This strategy is vulnerable to interannual oceanographic variability and long-term climatic changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koeller, P -- Fuentes-Yaco, C -- Platt, T -- Sathyendranath, S -- Richards, A -- Ouellet, P -- Orr, D -- Skuladottir, U -- Wieland, K -- Savard, L -- Aschan, M -- New York, N.Y. -- Science. 2009 May 8;324(5928):791-3. doi: 10.1126/science.1170987.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Fisheries and Oceans, Bedford Institute of Oceanography, Post Office Box 1006, Dartmouth, B2Y 4A2 Nova Scotia, Canada. koellerp@mar.dfo-mpo.gc.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19423827" target="_blank"〉PubMed〈/a〉

    Description: X-linked adrenoleukodystrophy (ALD) is a severe brain demyelinating disease in boys that is caused by a deficiency in ALD protein, an adenosine triphosphate-binding cassette transporter encoded by the ABCD1 gene. ALD progression can be halted by allogeneic hematopoietic cell transplantation (HCT). We initiated a gene therapy trial in two ALD patients for whom there were no matched donors. Autologous CD34+ cells were removed from the patients, genetically corrected ex vivo with a lentiviral vector encoding wild-type ABCD1, and then re-infused into the patients after they had received myeloablative treatment. Over a span of 24 to 30 months of follow-up, we detected polyclonal reconstitution, with 9 to 14% of granulocytes, monocytes, and T and B lymphocytes expressing the ALD protein. These results strongly suggest that hematopoietic stem cells were transduced in the patients. Beginning 14 to 16 months after infusion of the genetically corrected cells, progressive cerebral demyelination in the two patients stopped, a clinical outcome comparable to that achieved by allogeneic HCT. Thus, lentiviral-mediated gene therapy of hematopoietic stem cells can provide clinical benefits in ALD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cartier, Nathalie -- Hacein-Bey-Abina, Salima -- Bartholomae, Cynthia C -- Veres, Gabor -- Schmidt, Manfred -- Kutschera, Ina -- Vidaud, Michel -- Abel, Ulrich -- Dal-Cortivo, Liliane -- Caccavelli, Laure -- Mahlaoui, Nizar -- Kiermer, Veronique -- Mittelstaedt, Denice -- Bellesme, Celine -- Lahlou, Najiba -- Lefrere, Francois -- Blanche, Stephane -- Audit, Muriel -- Payen, Emmanuel -- Leboulch, Philippe -- l'Homme, Bruno -- Bougneres, Pierre -- Von Kalle, Christof -- Fischer, Alain -- Cavazzana-Calvo, Marina -- Aubourg, Patrick -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):818-23. doi: 10.1126/science.1171242.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM UMR745, University Paris-Descartes, 75279 Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892975" target="_blank"〉PubMed〈/a〉

    Description: Despite tremendous progress in understanding the nature of the immune system, the full diversity of an organism's antibody repertoire is unknown. We used high-throughput sequencing of the variable domain of the antibody heavy chain from 14 zebrafish to analyze VDJ usage and antibody sequence. Zebrafish were found to use between 50 and 86% of all possible VDJ combinations and shared a similar frequency distribution, with some correlation of VDJ patterns between individuals. Zebrafish antibodies retained a few thousand unique heavy chains that also exhibited a shared frequency distribution. We found evidence of convergence, in which different individuals made the same antibody. This approach provides insight into the breadth of the expressed antibody repertoire and immunological diversity at the level of an individual organism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3086368/" 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/PMC3086368/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weinstein, Joshua A -- Jiang, Ning -- White, Richard A 3rd -- Fisher, Daniel S -- Quake, Stephen R -- DP1 OD000251/OD/NIH HHS/ -- DP1 OD000251-04/OD/NIH HHS/ -- DP1 OD000251-05/OD/NIH HHS/ -- DP1 OD000251-06/OD/NIH HHS/ -- New York, N.Y. -- Science. 2009 May 8;324(5928):807-10. doi: 10.1126/science.1170020.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biophysics Program, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19423829" target="_blank"〉PubMed〈/a〉

    Description: Compared with more explicit racial slurs and statements, biased facial expressions and body language may resist conscious identification and thus produce a hidden social influence. In four studies, we show that race biases can be subtly transmitted via televised nonverbal behavior. Characters on 11 popular television shows exhibited more negative nonverbal behavior toward black than toward status-matched white characters. Critically, exposure to prowhite (versus problack) nonverbal bias increased viewers' bias even though patterns of nonverbal behavior could not be consciously reported. These findings suggest that hidden patterns of televised nonverbal behavior influence bias among viewers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3764987/" 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/PMC3764987/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weisbuch, Max -- Pauker, Kristin -- Ambady, Nalini -- F32 MH078350/MH/NIMH NIH HHS/ -- F32MH078350/MH/NIMH NIH HHS/ -- R01 MH070833/MH/NIMH NIH HHS/ -- R01 MH070833-02/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1711-4. doi: 10.1126/science.1178358.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Tufts University, 490 Boston Avenue, Medford, MA 02155, USA. max.weisbuch@tufts.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20019288" target="_blank"〉PubMed〈/a〉

    Description: Pleuropulmonary blastoma (PPB) is a rare pediatric lung tumor that is often part of an inherited cancer syndrome. PPBs consist of mesenchymal cells that are susceptible to malignant transformation and cysts lined by epithelial cells. In a subset of patients, overgrowth of the cysts by mesenchymal cells leads to sarcoma formation. Here, we show that 11 multiplex PPB families harbor heterozygous germline mutations in DICER1, a gene encoding an endoribonuclease critical to the generation of small noncoding regulatory RNAs. Expression of DICER1 protein was undetectable in the epithelial component of PPB tumors but was retained in the malignant mesenchyme (sarcoma). We hypothesize that loss of DICER1 in the epithelium of the developing lung alters the regulation of diffusible factors that promote mesenchymal proliferation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3098036/" 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/PMC3098036/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hill, D Ashley -- Ivanovich, Jennifer -- Priest, John R -- Gurnett, Christina A -- Dehner, Louis P -- Desruisseau, David -- Jarzembowski, Jason A -- Wikenheiser-Brokamp, Kathryn A -- Suarez, Brian K -- Whelan, Alison J -- Williams, Gretchen -- Bracamontes, Dawn -- Messinger, Yoav -- Goodfellow, Paul J -- P30 CA091842/CA/NCI NIH HHS/ -- P30 CA091842-07/CA/NCI NIH HHS/ -- P30 CA091842-08/CA/NCI NIH HHS/ -- R01 CA143167/CA/NCI NIH HHS/ -- R01 HL109265/HL/NHLBI NIH HHS/ -- UL1 RR024992/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 21;325(5943):965. doi: 10.1126/science.1174334.

    Description: Existing research reports inconsistent findings with regard to the effect of color on cognitive task performances. Some research suggests that blue or green leads to better performances than red; other studies record the opposite. Current work reconciles this discrepancy. We demonstrate that red (versus blue) color induces primarily an avoidance (versus approach) motivation (study 1, n = 69) and that red enhances performance on a detail-oriented task, whereas blue enhances performance on a creative task (studies 2 and 3, n = 208 and 118). Further, we replicate these results in the domains of product design (study 4, n = 42) and persuasive message evaluation (study 5, n = 161) and show that these effects occur outside of individuals' consciousness (study 6, n = 68). We also provide process evidence suggesting that the activation of alternative motivations mediates the effect of color on cognitive task performances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mehta, Ravi -- Zhu, Rui Juliet -- New York, N.Y. -- Science. 2009 Feb 27;323(5918):1226-9. doi: 10.1126/science.1169144.

    Description: Sexual conflict occurs when males and females act against each others' interest, typically resulting in selection favoring harmful males. We performed laboratory experiments on sexual conflict that both confined individuals in isolated groups, which prevents selection acting counter to this conflict, and provided more naturalistic multigroup population structures. We show that in water striders, aggressive male mating behavior was strongly favored within groups but not favored in a multigroup population when individuals can freely disperse among groups. These observations explain the persistence of less-aggressive males within natural populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eldakar, Omar Tonsi -- Dlugos, Michael J -- Pepper, John W -- Wilson, David Sloan -- 5 K12 GM000708/GM/NIGMS NIH HHS/ -- K12 GM000708/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):816. doi: 10.1126/science.1180183.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Insect Science, University of Arizona, Tucson, AZ 85721, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892974" target="_blank"〉PubMed〈/a〉

    Description: The familiar buzz of flying mosquitoes is an important mating signal, with the fundamental frequency of the female's flight tone signaling her presence. In the yellow fever and dengue vector Aedes aegypti, both sexes interact acoustically by shifting their flight tones to match, resulting in a courtship duet. Matching is made not at the fundamental frequency of 400 hertz (female) or 600 hertz (male) but at a shared harmonic of 1200 hertz, which exceeds the previously known upper limit of hearing in mosquitoes. Physiological recordings from Johnston's organ (the mosquito's "ear") reveal sensitivity up to 2000 hertz, consistent with our observed courtship behavior. These findings revise widely accepted limits of acoustic behavior in mosquitoes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2847473/" 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/PMC2847473/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cator, Lauren J -- Arthur, Ben J -- Harrington, Laura C -- Hoy, Ronald R -- R01 DC000103/DC/NIDCD NIH HHS/ -- R01 DC000103-34/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 20;323(5917):1077-9. doi: 10.1126/science.1166541.

    Description: The nuclear factor kappaB (NF-kappaB) transcription factor regulates cellular stress responses and the immune response to infection. NF-kappaB activation results in oscillations in nuclear NF-kappaB abundance. To define the function of these oscillations, we treated cells with repeated short pulses of tumor necrosis factor-alpha at various intervals to mimic pulsatile inflammatory signals. At all pulse intervals that were analyzed, we observed synchronous cycles of NF-kappaB nuclear translocation. Lower frequency stimulations gave repeated full-amplitude translocations, whereas higher frequency pulses gave reduced translocation, indicating a failure to reset. Deterministic and stochastic mathematical models predicted how negative feedback loops regulate both the resetting of the system and cellular heterogeneity. Altering the stimulation intervals gave different patterns of NF-kappaB-dependent gene expression, which supports the idea that oscillation frequency has a functional role.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2785900/" 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/PMC2785900/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ashall, Louise -- Horton, Caroline A -- Nelson, David E -- Paszek, Pawel -- Harper, Claire V -- Sillitoe, Kate -- Ryan, Sheila -- Spiller, David G -- Unitt, John F -- Broomhead, David S -- Kell, Douglas B -- Rand, David A -- See, Violaine -- White, Michael R H -- BB/C007158/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/C008219/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/C520471/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/D010748/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E004210/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E012965/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F005938/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBC0071581/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBC0082191/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBC5204711/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBD0107481/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBF0059381/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0500346/Medical Research Council/United Kingdom -- G0500346(73596)/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):242-6. doi: 10.1126/science.1164860.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Cell Imaging, School of Biological Sciences, Bioscience Research Building, Crown Street, Liverpool, L69 7ZB, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359585" target="_blank"〉PubMed〈/a〉

    Description: Schizophrenia is a devastating, highly heritable brain disorder of unknown etiology. Recently, the first common genetic variant associated on a genome-wide level with schizophrenia and possibly bipolar disorder was discovered in ZNF804A (rs1344706). We show, by using an imaging genetics approach, that healthy carriers of rs1344706 risk genotypes exhibit no changes in regional activity but pronounced gene dosage-dependent alterations in functional coupling (correlated activity) of dorsolateral prefrontal cortex (DLPFC) across hemispheres and with hippocampus, mirroring findings in patients, and abnormal coupling of amygdala. Our findings establish disturbed connectivity as a neurogenetic risk mechanism for psychosis supported by genome-wide association, show that rs1344706 or variation in linkage disequilibrium is functional in human brain, and validate the intermediate phenotype strategy in psychiatry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Esslinger, Christine -- Walter, Henrik -- Kirsch, Peter -- Erk, Susanne -- Schnell, Knut -- Arnold, Claudia -- Haddad, Leila -- Mier, Daniela -- Opitz von Boberfeld, Carola -- Raab, Kyeon -- Witt, Stephanie H -- Rietschel, Marcella -- Cichon, Sven -- Meyer-Lindenberg, Andreas -- New York, N.Y. -- Science. 2009 May 1;324(5927):605. doi: 10.1126/science.1167768.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry and Psychotherapy, Central Institute of Mental Health, University of Heidelberg, J5, 68159 Mannheim, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19407193" target="_blank"〉PubMed〈/a〉

    Description: A major transition in evolution is the origin of a division between reproduction and work among individuals. Nowhere is this divide more striking than in social insects, where workers rarely produce offspring even though they are often capable of reproduction should the queen or king die. The molecular mechanisms that control worker reproduction remain largely unknown. We used a combination of behavioral assays and RNA interference (RNAi) to identify a gene required for the reproductive division of labor between the queen and the workers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Korb, Judith -- Weil, Tobias -- Hoffmann, Katharina -- Foster, Kevin R -- Rehli, Michael -- New York, N.Y. -- Science. 2009 May 8;324(5928):758. doi: 10.1126/science.1170660.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Behavioral Biology, University of Osnabrueck, Barbarastrasse 11, D-49076 Osnabrueck, Germany. judith.korb@biologie.uni-osnabrueck.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19423819" target="_blank"〉PubMed〈/a〉

    Description: Actin filaments and microtubules polymerize and depolymerize by adding and removing subunits at polymer ends, and these dynamics drive cytoplasmic organization, cell division, and cell motility. Since Wegner proposed the treadmilling theory for actin in 1976, it has largely been assumed that the chemical state of the bound nucleotide determines the rates of subunit addition and removal. This chemical kinetics view is difficult to reconcile with observations revealing multiple structural states of the polymer that influence polymerization dynamics but that are not strictly coupled to the bound nucleotide state. We refer to these phenomena as "structural plasticity" and discuss emerging evidence that they play a central role in polymer dynamics and function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2864651/" 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/PMC2864651/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kueh, Hao Yuan -- Mitchison, Timothy J -- GM 23928/GM/NIGMS NIH HHS/ -- R01 GM023928/GM/NIGMS NIH HHS/ -- R01 GM023928-31/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Aug 21;325(5943):960-3. doi: 10.1126/science.1168823.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Systems Biology, Harvard Medical School, Boston, MA 02215, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19696342" target="_blank"〉PubMed〈/a〉

    Description: The genome of Mycoplasma pneumoniae is among the smallest found in self-replicating organisms. To study the basic principles of bacterial proteome organization, we used tandem affinity purification-mass spectrometry (TAP-MS) in a proteome-wide screen. The analysis revealed 62 homomultimeric and 116 heteromultimeric soluble protein complexes, of which the majority are novel. About a third of the heteromultimeric complexes show higher levels of proteome organization, including assembly into larger, multiprotein complex entities, suggesting sequential steps in biological processes, and extensive sharing of components, implying protein multifunctionality.

    Description: Hybrid sterility of the heterogametic sex is one of the first postzygotic reproductive barriers to evolve during speciation, yet the molecular basis of hybrid sterility is poorly understood. We show that the hybrid male sterility gene Odysseus-site homeobox (OdsH) encodes a protein that localizes to evolutionarily dynamic loci within heterochromatin and leads to their decondensation. In Drosophila mauritiana x Drosophila simulans male hybrids, OdsH from D. mauritiana (OdsHmau) acts as a sterilizing factor by associating with the heterochromatic Y chromosome of D. simulans, whereas D. simulans OdsH (OdsHsim) does not. Characterization of sterile hybrid testes revealed that OdsH abundance and localization in the premeiotic phases of spermatogenesis differ between species. These results reveal that rapid heterochromatin evolution affects the onset of hybrid sterility.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2987944/" 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/PMC2987944/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bayes, Joshua J -- Malik, Harmit S -- R01 GM074108/GM/NIGMS NIH HHS/ -- R01 GM074108-05/GM/NIGMS NIH HHS/ -- R01-GM74108/GM/NIGMS NIH HHS/ -- T32 GM07270/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1538-41. doi: 10.1126/science.1181756.

    Description: Mitochondria continuously undergo two opposing processes, fission and fusion. The disruption of this dynamic equilibrium may herald cell injury or death and may contribute to developmental and neurodegenerative disorders. Nitric oxide functions as a signaling molecule, but in excess it mediates neuronal injury, in part via mitochondrial fission or fragmentation. However, the underlying mechanism for nitric oxide-induced pathological fission remains unclear. We found that nitric oxide produced in response to beta-amyloid protein, thought to be a key mediator of Alzheimer's disease, triggered mitochondrial fission, synaptic loss, and neuronal damage, in part via S-nitrosylation of dynamin-related protein 1 (forming SNO-Drp1). Preventing nitrosylation of Drp1 by cysteine mutation abrogated these neurotoxic events. SNO-Drp1 is increased in brains of human Alzheimer's disease patients and may thus contribute to the pathogenesis of neurodegeneration.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2823371/" 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/PMC2823371/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cho, Dong-Hyung -- Nakamura, Tomohiro -- Fang, Jianguo -- Cieplak, Piotr -- Godzik, Adam -- Gu, Zezong -- Lipton, Stuart A -- P01 ES016738/ES/NIEHS NIH HHS/ -- P01 ES016738-01/ES/NIEHS NIH HHS/ -- P01 ES016738-010003/ES/NIEHS NIH HHS/ -- P01 ES016738-02/ES/NIEHS NIH HHS/ -- P01 ES016738-020003/ES/NIEHS NIH HHS/ -- P01 HD029587/HD/NICHD NIH HHS/ -- P01 HD029587-16/HD/NICHD NIH HHS/ -- P01 HD29587/HD/NICHD NIH HHS/ -- P30 NS057096/NS/NINDS NIH HHS/ -- P30 NS057096-04/NS/NINDS NIH HHS/ -- R01 EY005477/EY/NEI NIH HHS/ -- R01 EY005477-25/EY/NEI NIH HHS/ -- R01 EY05477/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 3;324(5923):102-5. doi: 10.1126/science.1171091.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Neuroscience, Aging, and Stem Cell Research, Burnham Institute for Medical Research, 10901 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19342591" target="_blank"〉PubMed〈/a〉

    Description: Two critical stages of mammalian oocyte regulation are prophase I arrest, which is important for sustaining the oocyte pool, and the progression through meiosis I (MI) to produce fertilizable eggs. We have found that the spindle assembly checkpoint protein BubR1 regulates both stages in mouse oocytes. We show that oocytes depleted of BubR1 cannot sustain prophase I arrest and readily undergo germinal vesicle breakdown, a marker for reentry into MI. BubR1-depleted oocytes then arrest before completing MI, marked by failure of polar body extrusion. Both meiotic defects in BubR1-depleted oocytes are due to reduced activity of the master regulator known as the anaphase-promoting complex (APC), brought about through diminished levels of the APC coactivator Cdh1.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3428834/" 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/PMC3428834/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Homer, Hayden -- Gui, Liming -- Carroll, John -- 082587/Wellcome Trust/United Kingdom -- 082587/Z/07/Z/Wellcome Trust/United Kingdom -- G0400530/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):991-4. doi: 10.1126/science.1175326.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Oocyte and Embryo Research Laboratory, Department of Cell and Developmental Biology, Division of Biosciences and Institute for Women's Health, University College London, London, UK. h.homer@ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965510" target="_blank"〉PubMed〈/a〉

    Description: Amyotrophic lateral sclerosis (ALS) is a fatal degenerative motor neuron disorder. Ten percent of cases are inherited; most involve unidentified genes. We report here 13 mutations in the fused in sarcoma/translated in liposarcoma (FUS/TLS) gene on chromosome 16 that were specific for familial ALS. The FUS/TLS protein binds to RNA, functions in diverse processes, and is normally located predominantly in the nucleus. In contrast, the mutant forms of FUS/TLS accumulated in the cytoplasm of neurons, a pathology that is similar to that of the gene TAR DNA-binding protein 43 (TDP43), whose mutations also cause ALS. Neuronal cytoplasmic protein aggregation and defective RNA metabolism thus appear to be common pathogenic mechanisms involved in ALS and possibly in other neurodegenerative disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kwiatkowski, T J Jr -- Bosco, D A -- Leclerc, A L -- Tamrazian, E -- Vanderburg, C R -- Russ, C -- Davis, A -- Gilchrist, J -- Kasarskis, E J -- Munsat, T -- Valdmanis, P -- Rouleau, G A -- Hosler, B A -- Cortelli, P -- de Jong, P J -- Yoshinaga, Y -- Haines, J L -- Pericak-Vance, M A -- Yan, J -- Ticozzi, N -- Siddique, T -- McKenna-Yasek, D -- Sapp, P C -- Horvitz, H R -- Landers, J E -- Brown, R H Jr -- New York, N.Y. -- Science. 2009 Feb 27;323(5918):1205-8. doi: 10.1126/science.1166066.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Massachusetts General Hospital, 114 16th Street, Charlestown, MA 02129, USA. tkwiatkowski@partners.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19251627" target="_blank"〉PubMed〈/a〉

    Description: Although the nematode Caenorhabditis elegans produces self-fertile hermaphrodites, it descended from a male/female species, so hermaphroditism provides a model for the origin of novel traits. In the related species C. remanei, which has only male and female sexes, lowering the activity of tra-2 by RNA interference created XX animals that made spermatids as well as oocytes, but their spermatids could not activate without the addition of male seminal fluid. However, by lowering the expression of both tra-2 and swm-1, a gene that regulates sperm activation in C. elegans, we produced XX animals with active sperm that were self-fertile. Thus, the evolution of hermaphroditism in Caenorhabditis probably required two steps: a mutation in the sex-determination pathway that caused XX spermatogenesis and a mutation that allowed these spermatids to self-activate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baldi, Chris -- Cho, Soochin -- Ellis, Ronald E -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):1002-5. doi: 10.1126/science.1176013.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate School of Biomedical Sciences, University of Medicine and Dentistry of New Jersey, Stratford, NJ 08084, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965511" target="_blank"〉PubMed〈/a〉

    Description: Dynamin-related proteins (DRPs) can generate forces to remodel membranes. In cells, DRPs require additional proteins [DRP-associated proteins (DAPs)] to conduct their functions. To dissect the mechanistic role of a DAP, we used the yeast mitochondrial division machine as a model, which requires the DRP Dnm1, and two other proteins, Mdv1 and Fis1. Mdv1 played a postmitochondrial targeting role in division by specifically interacting and coassembling with the guanosine triphosphate-bound form of Dnm1. This regulated interaction nucleated and promoted the self-assembly of Dnm1 into helical structures, which drive membrane scission. The nucleation of DRP assembly probably represents a general regulatory strategy for this family of filament-forming proteins, similar to F-actin regulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lackner, Laura L -- Horner, Jennifer S -- Nunnari, Jodi -- 1F32GM078749/GM/NIGMS NIH HHS/ -- R01 GM062942/GM/NIGMS NIH HHS/ -- R01GM062942/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 14;325(5942):874-7. doi: 10.1126/science.1176921.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, University of California, Davis, CA 95616, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19679814" target="_blank"〉PubMed〈/a〉

    Description: Insect wings are complex structures that deform dramatically in flight. We analyzed the aerodynamic consequences of wing deformation in locusts using a three-dimensional computational fluid dynamics simulation based on detailed wing kinematics. We validated the simulation against smoke visualizations and digital particle image velocimetry on real locusts. We then used the validated model to explore the effects of wing topography and deformation, first by removing camber while keeping the same time-varying twist distribution, and second by removing camber and spanwise twist. The full-fidelity model achieved greater power economy than the uncambered model, which performed better than the untwisted model, showing that the details of insect wing topography and deformation are important aerodynamically. Such details are likely to be important in engineering applications of flapping flight.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Young, John -- Walker, Simon M -- Bomphrey, Richard J -- Taylor, Graham K -- Thomas, Adrian L R -- 204513/European Research Council/International -- New York, N.Y. -- Science. 2009 Sep 18;325(5947):1549-52. doi: 10.1126/science.1175928.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Engineering and Information Technology, University of New South Wales, Australian Defence Force Academy, Canberra, Australian Capital Territory 2600, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19762645" target="_blank"〉PubMed〈/a〉

    Description: The brain's sensitivity to unexpected outcomes plays a fundamental role in an organism's ability to adapt and learn new behaviors. Emerging research suggests that midbrain dopaminergic neurons encode these unexpected outcomes. We used microelectrode recordings during deep brain stimulation surgery to study neuronal activity in the human substantia nigra (SN) while patients with Parkinson's disease engaged in a probabilistic learning task motivated by virtual financial rewards. Based on a model of the participants' expected reward, we divided trial outcomes into expected and unexpected gains and losses. SN neurons exhibited significantly higher firing rates after unexpected gains than unexpected losses. No such differences were observed after expected gains and losses. This result provides critical support for the hypothesized role of the SN in human reinforcement learning.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2839450/" 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/PMC2839450/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zaghloul, Kareem A -- Blanco, Justin A -- Weidemann, Christoph T -- McGill, Kathryn -- Jaggi, Jurg L -- Baltuch, Gordon H -- Kahana, Michael J -- MH062196/MH/NIMH NIH HHS/ -- MH61975/MH/NIMH NIH HHS/ -- P50 MH062196/MH/NIMH NIH HHS/ -- P50 MH062196-090008/MH/NIMH NIH HHS/ -- R01 MH061975/MH/NIMH NIH HHS/ -- R01 MH061975-08/MH/NIMH NIH HHS/ -- R01 NS048598/NS/NINDS NIH HHS/ -- R01 NS048598-04/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 13;323(5920):1496-9. doi: 10.1126/science.1167342.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurosurgery, University of Pennsylvania, Philadelphia, PA 19104, USA. zaghlouk@uphs.upenn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19286561" target="_blank"〉PubMed〈/a〉

    Description: We tested whether classroom activities that encourage students to connect course materials to their lives will increase student motivation and learning. We hypothesized that this effect will be stronger for students who have low expectations of success. In a randomized field experiment with high school students, we found that a relevance intervention, which encouraged students to make connections between their lives and what they were learning in their science courses, increased interest in science and course grades for students with low success expectations. The results have implications for the development of science curricula and theories of motivation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hulleman, Chris S -- Harackiewicz, Judith M -- New York, N.Y. -- Science. 2009 Dec 4;326(5958):1410-2. doi: 10.1126/science.1177067.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Graduate Psychology, James Madison University, Harrisonburg, VA 22807, USA. hullemcs@jmu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965759" target="_blank"〉PubMed〈/a〉

    Description: Evolution may be dominated by biotic factors, as in the Red Queen model, or abiotic factors, as in the Court Jester model, or a mixture of both. The two models appear to operate predominantly over different geographic and temporal scales: Competition, predation, and other biotic factors shape ecosystems locally and over short time spans, but extrinsic factors such as climate and oceanographic and tectonic events shape larger-scale patterns regionally and globally, and through thousands and millions of years. Paleobiological studies suggest that species diversity is driven largely by abiotic factors such as climate, landscape, or food supply, and comparative phylogenetic approaches offer new insights into clade dynamics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benton, Michael J -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):728-32. doi: 10.1126/science.1157719.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, University of Bristol, Bristol BS8 1RJ, UK. mike.benton@bristol.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197051" target="_blank"〉PubMed〈/a〉

    Description: The dentate gyrus (DG) of the mammalian hippocampus is hypothesized to mediate pattern separation-the formation of distinct and orthogonal representations of mnemonic information-and also undergoes neurogenesis throughout life. How neurogenesis contributes to hippocampal function is largely unknown. Using adult mice in which hippocampal neurogenesis was ablated, we found specific impairments in spatial discrimination with two behavioral assays: (i) a spatial navigation radial arm maze task and (ii) a spatial, but non-navigable, task in the mouse touch screen. Mice with ablated neurogenesis were impaired when stimuli were presented with little spatial separation, but not when stimuli were more widely separated in space. Thus, newborn neurons may be necessary for normal pattern separation function in the DG of adult mice.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997634/" 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/PMC2997634/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clelland, C D -- Choi, M -- Romberg, C -- Clemenson, G D Jr -- Fragniere, A -- Tyers, P -- Jessberger, S -- Saksida, L M -- Barker, R A -- Gage, F H -- Bussey, T J -- NS-050217/NS/NINDS NIH HHS/ -- R01 NS050217/NS/NINDS NIH HHS/ -- R01 NS050217-05/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 10;325(5937):210-3. doi: 10.1126/science.1173215.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, Salk Institute for Biological Studies, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19590004" target="_blank"〉PubMed〈/a〉

    Description: A major cause for biodiversity may be biodiversity itself. As new species form, they may create new niches for others to exploit, potentially catalyzing a chain reaction of speciation events across trophic levels. We tested for such sequential radiation in the Rhagoletis pomonella (Diptera: Tephritidae) complex, a model for sympatric speciation via host plant shifting. We report that the parasitic wasp Diachasma alloeum (Hymenoptera: Braconidae) has formed new incipient species as a result of specializing on diversifying fly hosts, including the recently derived apple-infesting race of R. pomonella. Furthermore, we show that traits that differentially adapt R. pomonella flies to their host plants have also quickly evolved and serve as ecological barriers to reproduction, isolating the wasps. Speciation therefore cascades as the effects of new niche construction move across trophic levels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Forbes, Andrew A -- Powell, Thomas H Q -- Stelinski, Lukasz L -- Smith, James J -- Feder, Jeffrey L -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):776-9. doi: 10.1126/science.1166981.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Notre Dame, Galvin Life Sciences Building, Notre Dame, IN 46556, USA. aaforbes@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197063" target="_blank"〉PubMed〈/a〉

    Description: After a long history of overexploitation, increasing efforts to restore marine ecosystems and rebuild fisheries are under way. Here, we analyze current trends from a fisheries and conservation perspective. In 5 of 10 well-studied ecosystems, the average exploitation rate has recently declined and is now at or below the rate predicted to achieve maximum sustainable yield for seven systems. Yet 63% of assessed fish stocks worldwide still require rebuilding, and even lower exploitation rates are needed to reverse the collapse of vulnerable species. Combined fisheries and conservation objectives can be achieved by merging diverse management actions, including catch restrictions, gear modification, and closed areas, depending on local context. Impacts of international fleets and the lack of alternatives to fishing complicate prospects for rebuilding fisheries in many poorer regions, highlighting the need for a global perspective on rebuilding marine resources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worm, Boris -- Hilborn, Ray -- Baum, Julia K -- Branch, Trevor A -- Collie, Jeremy S -- Costello, Christopher -- Fogarty, Michael J -- Fulton, Elizabeth A -- Hutchings, Jeffrey A -- Jennings, Simon -- Jensen, Olaf P -- Lotze, Heike K -- Mace, Pamela M -- McClanahan, Tim R -- Minto, Coilin -- Palumbi, Stephen R -- Parma, Ana M -- Ricard, Daniel -- Rosenberg, Andrew A -- Watson, Reg -- Zeller, Dirk -- New York, N.Y. -- Science. 2009 Jul 31;325(5940):578-85. doi: 10.1126/science.1173146.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biology Department, Dalhousie University, Halifax, NS B3H 4J1, Canada. bworm@dal.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19644114" target="_blank"〉PubMed〈/a〉

    Description: Biologists have long been fascinated by the exceptionally high diversity displayed by some evolutionary groups. Adaptive radiation in such clades is not only spectacular, but is also an extremely complex process influenced by a variety of ecological, genetic, and developmental factors and strongly dependent on historical contingencies. Using modeling approaches, we identify 10 general patterns concerning the temporal, spatial, and genetic/morphological properties of adaptive radiation. Some of these are strongly supported by empirical work, whereas for others, empirical support is more tentative. In almost all cases, more data are needed. Future progress in our understanding of adaptive radiation will be most successful if theoretical and empirical approaches are integrated, as has happened in other areas of evolutionary biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gavrilets, Sergey -- Losos, Jonathan B -- GM56693/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):732-7. doi: 10.1126/science.1157966.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, National Institute for Mathematical and Biological Synthesis, University of Tennessee, Knoxville, TN 37996, USA. sergey@tiem.utk.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197052" target="_blank"〉PubMed〈/a〉

    Description: The extracellular matrix (ECM) and ECM proteins are important in phenomena as diverse as developmental patterning, stem cell niches, cancer, and genetic diseases. The ECM has many effects beyond providing structural support. ECM proteins typically include multiple, independently folded domains whose sequences and arrangement are highly conserved. Some of these domains bind adhesion receptors such as integrins that mediate cell-matrix adhesion and also transduce signals into cells. However, ECM proteins also bind soluble growth factors and regulate their distribution, activation, and presentation to cells. As organized, solid-phase ligands, ECM proteins can integrate complex, multivalent signals to cells in a spatially patterned and regulated fashion. These properties need to be incorporated into considerations of the functions of the ECM.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3536535/" 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/PMC3536535/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hynes, Richard O -- P01 HL066105/HL/NHLBI NIH HHS/ -- R01 CA017007/CA/NCI NIH HHS/ -- U54 CA126515/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1216-9. doi: 10.1126/science.1176009.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, David H.

    Description: Determining proper responsiveness to incoming signals is fundamental to all biological systems. We demonstrate that intracellular signaling nodes can tune a signaling network's response threshold away from the basal median effective concentration established by ligand-receptor interactions. Focusing on the bistable kinase network that governs progesterone-induced meiotic entry in Xenopus oocytes, we characterized glycogen synthase kinase-3beta (GSK-3beta) as a dampener of progesterone responsiveness. GSK-3beta engages the meiotic kinase network through a double-negative feedback loop; this specific feedback architecture raises the progesterone threshold in correspondence with the strength of double-negative signaling. We also identified a marker of nutritional status, l-leucine, which lowers the progesterone threshold, indicating that oocytes integrate additional signals into their cell-fate decisions by modulating progesterone responsiveness.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2880456/" 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/PMC2880456/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Justman, Quincey A -- Serber, Zach -- Ferrell, James E Jr -- El-Samad, Hana -- Shokat, Kevan M -- AI49006/AI/NIAID NIH HHS/ -- GM46383/GM/NIGMS NIH HHS/ -- R01 AI044009/AI/NIAID NIH HHS/ -- R01 AI044009-10/AI/NIAID NIH HHS/ -- R01 GM046383/GM/NIGMS NIH HHS/ -- R01 GM046383-19/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Apr 24;324(5926):509-12. doi: 10.1126/science.1169498.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Group in Biophysics, University of California, San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19390045" target="_blank"〉PubMed〈/a〉

    Description: A single-base pair resolution silkworm genetic variation map was constructed from 40 domesticated and wild silkworms, each sequenced to approximately threefold coverage, representing 99.88% of the genome. We identified ~16 million single-nucleotide polymorphisms, many indels, and structural variations. We find that the domesticated silkworms are clearly genetically differentiated from the wild ones, but they have maintained large levels of genetic variability, suggesting a short domestication event involving a large number of individuals. We also identified signals of selection at 354 candidate genes that may have been important during domestication, some of which have enriched expression in the silk gland, midgut, and testis. These data add to our understanding of the domestication processes and may have applications in devising pest control strategies and advancing the use of silkworms as efficient bioreactors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951477/" 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/PMC3951477/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xia, Qingyou -- Guo, Yiran -- Zhang, Ze -- Li, Dong -- Xuan, Zhaoling -- Li, Zhuo -- Dai, Fangyin -- Li, Yingrui -- Cheng, Daojun -- Li, Ruiqiang -- Cheng, Tingcai -- Jiang, Tao -- Becquet, Celine -- Xu, Xun -- Liu, Chun -- Zha, Xingfu -- Fan, Wei -- Lin, Ying -- Shen, Yihong -- Jiang, Lan -- Jensen, Jeffrey -- Hellmann, Ines -- Tang, Si -- Zhao, Ping -- Xu, Hanfu -- Yu, Chang -- Zhang, Guojie -- Li, Jun -- Cao, Jianjun -- Liu, Shiping -- He, Ningjia -- Zhou, Yan -- Liu, Hui -- Zhao, Jing -- Ye, Chen -- Du, Zhouhe -- Pan, Guoqing -- Zhao, Aichun -- Shao, Haojing -- Zeng, Wei -- Wu, Ping -- Li, Chunfeng -- Pan, Minhui -- Li, Jingjing -- Yin, Xuyang -- Li, Dawei -- Wang, Juan -- Zheng, Huisong -- Wang, Wen -- Zhang, Xiuqing -- Li, Songgang -- Yang, Huanming -- Lu, Cheng -- Nielsen, Rasmus -- Zhou, Zeyang -- Wang, Jian -- Xiang, Zhonghuai -- Wang, Jun -- R01 HG003229/HG/NHGRI NIH HHS/ -- R01 HG003229-05/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 16;326(5951):433-6. doi: 10.1126/science.1176620.

    Description: Many species of parasitoid wasps inject polydnavirus particles in order to manipulate host defenses and development. Because the DNA packaged in these particles encodes almost no viral structural proteins, their relation to viruses has been debated. Characterization of complementary DNAs derived from braconid wasp ovaries identified genes encoding subunits of a viral RNA polymerase and structural components of polydnavirus particles related most closely to those of nudiviruses--a sister group of baculoviruses. The conservation of this viral machinery in different braconid wasp lineages sharing polydnaviruses suggests that parasitoid wasps incorporated a nudivirus-related genome into their own genetic material. We found that the nudiviral genes themselves are no longer packaged but are actively transcribed and produce particles used to deliver genes essential for successful parasitism in lepidopteran hosts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bezier, Annie -- Annaheim, Marc -- Herbiniere, Juline -- Wetterwald, Christoph -- Gyapay, Gabor -- Bernard-Samain, Sylvie -- Wincker, Patrick -- Roditi, Isabel -- Heller, Manfred -- Belghazi, Maya -- Pfister-Wilhem, Rita -- Periquet, Georges -- Dupuy, Catherine -- Huguet, Elisabeth -- Volkoff, Anne-Nathalie -- Lanzrein, Beatrice -- Drezen, Jean-Michel -- New York, N.Y. -- Science. 2009 Feb 13;323(5916):926-30. doi: 10.1126/science.1166788.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Recherche sur la Biologie de l'Insecte, CNRS UMR 6035, Universite Francois Rabelais, Parc de Grandmont, 37200 Tours, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19213916" target="_blank"〉PubMed〈/a〉

    Description: Metabolic pathways have traditionally been described in terms of biochemical reactions and metabolites. With the use of structural genomics and systems biology, we generated a three-dimensional reconstruction of the central metabolic network of the bacterium Thermotoga maritima. The network encompassed 478 proteins, of which 120 were determined by experiment and 358 were modeled. Structural analysis revealed that proteins forming the network are dominated by a small number (only 182) of basic shapes (folds) performing diverse but mostly related functions. Most of these folds are already present in the essential core (approximately 30%) of the network, and its expansion by nonessential proteins is achieved with relatively few additional folds. Thus, integration of structural data with networks analysis generates insight into the function, mechanism, and evolution of biological networks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2833182/" 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/PMC2833182/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Ying -- Thiele, Ines -- Weekes, Dana -- Li, Zhanwen -- Jaroszewski, Lukasz -- Ginalski, Krzysztof -- Deacon, Ashley M -- Wooley, John -- Lesley, Scott A -- Wilson, Ian A -- Palsson, Bernhard -- Osterman, Andrei -- Godzik, Adam -- P20 GM076221/GM/NIGMS NIH HHS/ -- P20 GM076221-03/GM/NIGMS NIH HHS/ -- U54 GM074898/GM/NIGMS NIH HHS/ -- U54 GM074898-05/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Sep 18;325(5947):1544-9. doi: 10.1126/science.1174671.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Joint Center for Molecular Modeling (JCMM), Burnham Institute for Medical Research, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19762644" target="_blank"〉PubMed〈/a〉

    Description: Heterozygous mutations in the gene encoding isocitrate dehydrogenase-1 (IDH1) occur in certain human brain tumors, but their mechanistic role in tumor development is unknown. We have shown that tumor-derived IDH1 mutations impair the enzyme's affinity for its substrate and dominantly inhibit wild-type IDH1 activity through the formation of catalytically inactive heterodimers. Forced expression of mutant IDH1 in cultured cells reduces formation of the enzyme product, alpha-ketoglutarate (alpha-KG), and increases the levels of hypoxia-inducible factor subunit HIF-1alpha, a transcription factor that facilitates tumor growth when oxygen is low and whose stability is regulated by alpha-KG. The rise in HIF-1alpha levels was reversible by an alpha-KG derivative. HIF-1alpha levels were higher in human gliomas harboring an IDH1 mutation than in tumors without a mutation. Thus, IDH1 appears to function as a tumor suppressor that, when mutationally inactivated, contributes to tumorigenesis in part through induction of the HIF-1 pathway.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3251015/" 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/PMC3251015/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Shimin -- Lin, Yan -- Xu, Wei -- Jiang, Wenqing -- Zha, Zhengyu -- Wang, Pu -- Yu, Wei -- Li, Zhiqiang -- Gong, Lingling -- Peng, Yingjie -- Ding, Jianping -- Lei, Qunying -- Guan, Kun-Liang -- Xiong, Yue -- R01 CA068377/CA/NCI NIH HHS/ -- R01 CA068377-14/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):261-5. doi: 10.1126/science.1170944.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular and Cell Biology Laboratory, Institute of Biomedical Sciences, Fudan University, 130 Dong-An Road, Shanghai 200032, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359588" target="_blank"〉PubMed〈/a〉

    Description: The toolbox of rat genetics currently lacks the ability to introduce site-directed, heritable mutations into the genome to create knockout animals. By using engineered zinc-finger nucleases (ZFNs) designed to target an integrated reporter and two endogenous rat genes, Immunoglobulin M (IgM) and Rab38, we demonstrate that a single injection of DNA or messenger RNA encoding ZFNs into the one-cell rat embryo leads to a high frequency of animals carrying 25 to 100% disruption at the target locus. These mutations are faithfully and efficiently transmitted through the germline. Our data demonstrate the feasibility of targeted gene disruption in multiple rat strains within 4 months time, paving the way to a humanized monoclonal antibody platform and additional human disease models.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2831805/" 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/PMC2831805/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Geurts, Aron M -- Cost, Gregory J -- Freyvert, Yevgeniy -- Zeitler, Bryan -- Miller, Jeffrey C -- Choi, Vivian M -- Jenkins, Shirin S -- Wood, Adam -- Cui, Xiaoxia -- Meng, Xiangdong -- Vincent, Anna -- Lam, Stephen -- Michalkiewicz, Mieczyslaw -- Schilling, Rebecca -- Foeckler, Jamie -- Kalloway, Shawn -- Weiler, Hartmut -- Menoret, Severine -- Anegon, Ignacio -- Davis, Gregory D -- Zhang, Lei -- Rebar, Edward J -- Gregory, Philip D -- Urnov, Fyodor D -- Jacob, Howard J -- Buelow, Roland -- 5P01HL082798-03/HL/NHLBI NIH HHS/ -- 5U01HL066579-08/HL/NHLBI NIH HHS/ -- P01 HL082798/HL/NHLBI NIH HHS/ -- P01 HL082798-03/HL/NHLBI NIH HHS/ -- U01 HL066579/HL/NHLBI NIH HHS/ -- U01 HL066579-08/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 24;325(5939):433. doi: 10.1126/science.1172447.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human and Molecular Genetics Center, Medical College of Wisconsin, Milwaukee, WI 52336, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19628861" target="_blank"〉PubMed〈/a〉

    Description: A current paradigm states that monocytes circulate freely and patrol blood vessels but differentiate irreversibly into dendritic cells (DCs) or macrophages upon tissue entry. Here we show that bona fide undifferentiated monocytes reside in the spleen and outnumber their equivalents in circulation. The reservoir monocytes assemble in clusters in the cords of the subcapsular red pulp and are distinct from macrophages and DCs. In response to ischemic myocardial injury, splenic monocytes increase their motility, exit the spleen en masse, accumulate in injured tissue, and participate in wound healing. These observations uncover a role for the spleen as a site for storage and rapid deployment of monocytes and identify splenic monocytes as a resource that the body exploits to regulate inflammation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2803111/" 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/PMC2803111/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Swirski, Filip K -- Nahrendorf, Matthias -- Etzrodt, Martin -- Wildgruber, Moritz -- Cortez-Retamozo, Virna -- Panizzi, Peter -- Figueiredo, Jose-Luiz -- Kohler, Rainer H -- Chudnovskiy, Aleksey -- Waterman, Peter -- Aikawa, Elena -- Mempel, Thorsten R -- Libby, Peter -- Weissleder, Ralph -- Pittet, Mikael J -- 1R01HL095612/HL/NHLBI NIH HHS/ -- P01 A154904/PHS HHS/ -- P01 AI054904/AI/NIAID NIH HHS/ -- P01 AI054904-010001/AI/NIAID NIH HHS/ -- P50 CA086355/CA/NCI NIH HHS/ -- P50 CA086355-07/CA/NCI NIH HHS/ -- P50 CA86355/CA/NCI NIH HHS/ -- R00 HL094533/HL/NHLBI NIH HHS/ -- R01 HL095629/HL/NHLBI NIH HHS/ -- R01 HL096576/HL/NHLBI NIH HHS/ -- R24 CA69246/CA/NCI NIH HHS/ -- U01 HL080731/HL/NHLBI NIH HHS/ -- U01 HL080731-05/HL/NHLBI NIH HHS/ -- U54 CA126515/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 31;325(5940):612-6. doi: 10.1126/science.1175202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Systems Biology, Massachusetts General Hospital and Harvard Medical School, Boston, MA 02114, USA. fswirski@mgh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19644120" target="_blank"〉PubMed〈/a〉

    Description: Sex determination mechanisms differ among animal species, but it is not clear how these differences evolve. New sex determiners may arise in response to sexual conflicts, which occur when traits benefit one sex but hinder the other. We identified the genetic basis for the orange-blotch (OB) color pattern, a trait under sexually antagonistic selection in the cichlid fish of Lake Malawi, East Africa. The OB phenotype is due to a cis-regulatory mutation in the Pax7 gene. OB provides benefits of camouflage to females but disrupts the species-specific male color patterns used for mate recognition. We suggest that the resulting sexual conflict over the OB allele has been resolved by selection for a novel female sex determination locus that has invaded populations with an ancestral male sex determination system.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3174268/" 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/PMC3174268/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, Reade B -- Ser, Jennifer R -- Kocher, Thomas D -- F32HD051383/HD/NICHD NIH HHS/ -- R01 HD058635/HD/NICHD NIH HHS/ -- R01 HD058635-04/HD/NICHD NIH HHS/ -- R01HD058635/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):998-1001. doi: 10.1126/science.1174705.

    Description: The imprints of domestication and breed development on the genomes of livestock likely differ from those of companion animals. A deep draft sequence assembly of shotgun reads from a single Hereford female and comparative sequences sampled from six additional breeds were used to develop probes to interrogate 37,470 single-nucleotide polymorphisms (SNPs) in 497 cattle from 19 geographically and biologically diverse breeds. These data show that cattle have undergone a rapid recent decrease in effective population size from a very large ancestral population, possibly due to bottlenecks associated with domestication, selection, and breed formation. Domestication and artificial selection appear to have left detectable signatures of selection within the cattle genome, yet the current levels of diversity within breeds are at least as great as exists within humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2735092/" 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/PMC2735092/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bovine HapMap Consortium -- Gibbs, Richard A -- Taylor, Jeremy F -- Van Tassell, Curtis P -- Barendse, William -- Eversole, Kellye A -- Gill, Clare A -- Green, Ronnie D -- Hamernik, Debora L -- Kappes, Steven M -- Lien, Sigbjorn -- Matukumalli, Lakshmi K -- McEwan, John C -- Nazareth, Lynne V -- Schnabel, Robert D -- Weinstock, George M -- Wheeler, David A -- Ajmone-Marsan, Paolo -- Boettcher, Paul J -- Caetano, Alexandre R -- Garcia, Jose Fernando -- Hanotte, Olivier -- Mariani, Paola -- Skow, Loren C -- Sonstegard, Tad S -- Williams, John L -- Diallo, Boubacar -- Hailemariam, Lemecha -- Martinez, Mario L -- Morris, Chris A -- Silva, Luiz O C -- Spelman, Richard J -- Mulatu, Woudyalew -- Zhao, Keyan -- Abbey, Colette A -- Agaba, Morris -- Araujo, Flabio R -- Bunch, Rowan J -- Burton, James -- Gorni, Chiara -- Olivier, Hanotte -- Harrison, Blair E -- Luff, Bill -- Machado, Marco A -- Mwakaya, Joel -- Plastow, Graham -- Sim, Warren -- Smith, Timothy -- Thomas, Merle B -- Valentini, Alessio -- Williams, Paul -- Womack, James -- Woolliams, John A -- Liu, Yue -- Qin, Xiang -- Worley, Kim C -- Gao, Chuan -- Jiang, Huaiyang -- Moore, Stephen S -- Ren, Yanru -- Song, Xing-Zhi -- Bustamante, Carlos D -- Hernandez, Ryan D -- Muzny, Donna M -- Patil, Shobha -- San Lucas, Anthony -- Fu, Qing -- Kent, Matthew P -- Vega, Richard -- Matukumalli, Aruna -- McWilliam, Sean -- Sclep, Gert -- Bryc, Katarzyna -- Choi, Jungwoo -- Gao, Hong -- Grefenstette, John J -- Murdoch, Brenda -- Stella, Alessandra -- Villa-Angulo, Rafael -- Wright, Mark -- Aerts, Jan -- Jann, Oliver -- Negrini, Riccardo -- Goddard, Mike E -- Hayes, Ben J -- Bradley, Daniel G -- Barbosa da Silva, Marcos -- Lau, Lilian P L -- Liu, George E -- Lynn, David J -- Panzitta, Francesca -- Dodds, Ken G -- R01 GM083606/GM/NIGMS NIH HHS/ -- R01 GM083606-02/GM/NIGMS NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 24;324(5926):528-32. doi: 10.1126/science.1167936.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19390050" target="_blank"〉PubMed〈/a〉

    Description: In the early stages of viral infection, outcomes depend on a race between expansion of infection and the immune response generated to contain it. We combined in situ tetramer staining with in situ hybridization to visualize, map, and quantify relationships between immune effector cells and their targets in tissues. In simian immunodeficiency virus infections in macaques and lymphocytic choriomeningitis virus infections in mice, the magnitude and timing of the establishment of an excess of effector cells versus targets were found to correlate with the extent of control and the infection outcome (i.e., control and clearance versus partial or poor control and persistent infection). This method highlights the importance of the location, timing, and magnitude of the immune response needed for a vaccine to be effective against agents of persistent infection, such as HIV-1.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2753492/" 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/PMC2753492/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Qingsheng -- Skinner, Pamela J -- Ha, Sang-Jun -- Duan, Lijie -- Mattila, Teresa L -- Hage, Aaron -- White, Cara -- Barber, Daniel L -- O'Mara, Leigh -- Southern, Peter J -- Reilly, Cavan S -- Carlis, John V -- Miller, Christopher J -- Ahmed, Rafi -- Haase, Ashley T -- AI066314/AI/NIAID NIH HHS/ -- AI20048/AI/NIAID NIH HHS/ -- AI48484/AI/NIAID NIH HHS/ -- P01 AI066314/AI/NIAID NIH HHS/ -- P01 AI066314-010003/AI/NIAID NIH HHS/ -- P01 AI066314-020003/AI/NIAID NIH HHS/ -- P01 AI066314-030003/AI/NIAID NIH HHS/ -- P01 AI066314-040003/AI/NIAID NIH HHS/ -- P51 RR000169/RR/NCRR NIH HHS/ -- P51 RR000169-430198/RR/NCRR NIH HHS/ -- R01 AI048484/AI/NIAID NIH HHS/ -- R01 AI048484-01/AI/NIAID NIH HHS/ -- R01 AI048484-02/AI/NIAID NIH HHS/ -- R01 AI048484-03/AI/NIAID NIH HHS/ -- R01 AI048484-04/AI/NIAID NIH HHS/ -- RR00169/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1726-9. doi: 10.1126/science.1168676.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Medical School, University of Minnesota, Minneapolis, MN 55455, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19325114" target="_blank"〉PubMed〈/a〉

    Description: Two experiments revealed that (i) people can more accurately predict their affective reactions to a future event when they know how a neighbor in their social network reacted to the event than when they know about the event itself and (ii) people do not believe this. Undergraduates made more accurate predictions about their affective reactions to a 5-minute speed date (n = 25) and to a peer evaluation (n = 88) when they knew only how another undergraduate had reacted to these events than when they had information about the events themselves. Both participants and independent judges mistakenly believed that predictions based on information about the event would be more accurate than predictions based on information about how another person had reacted to it.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gilbert, Daniel T -- Killingsworth, Matthew A -- Eyre, Rebecca N -- Wilson, Timothy D -- New York, N.Y. -- Science. 2009 Mar 20;323(5921):1617-9. doi: 10.1126/science.1166632.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Harvard University, Cambridge, MA 02138, USA. gilbert@wjh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19299622" target="_blank"〉PubMed〈/a〉

    Description: Sleep is universal, strictly regulated, and necessary for cognition. Why this is so remains a mystery, although recent work suggests that sleep, memory, and plasticity are linked. However, little is known about how wakefulness and sleep affect synapses. Using Western blots and confocal microscopy in Drosophila, we found that protein levels of key components of central synapses were high after waking and low after sleep. These changes were related to behavioral state rather than time of day and occurred in all major areas of the Drosophila brain. The decrease of synaptic markers during sleep was progressive, and sleep was necessary for their decline. Thus, sleep may be involved in maintaining synaptic homeostasis altered by waking activities.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2715914/" 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/PMC2715914/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gilestro, Giorgio F -- Tononi, Giulio -- Cirelli, Chiara -- DP1 OD000579/OD/NIH HHS/ -- DP1 OD000579-01/OD/NIH HHS/ -- DP1 OD000579-02/OD/NIH HHS/ -- DP1 OD000579-03/OD/NIH HHS/ -- DP1 OD000579-04/OD/NIH HHS/ -- R01 GM075315/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 3;324(5923):109-12. doi: 10.1126/science.1166673.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of Wisconsin, Madison, WI 53719, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19342593" target="_blank"〉PubMed〈/a〉

    Description: Successful cell division requires that chromosomes attach to opposite poles of the mitotic spindle (bi-orientation). Aurora B kinase regulates chromosome-spindle attachments by phosphorylating kinetochore substrates that bind microtubules. Centromere tension stabilizes bi-oriented attachments, but how physical forces are translated into signaling at individual centromeres is unknown. Using fluorescence resonance energy transfer-based biosensors to measure localized phosphorylation dynamics in living cells, we found that phosphorylation of an Aurora B substrate at the kinetochore depended on its distance from the kinase at the inner centromere. Furthermore, repositioning Aurora B closer to the kinetochore prevented stabilization of bi-oriented attachments and activated the spindle checkpoint. Thus, centromere tension can be sensed by increased spatial separation of Aurora B from kinetochore substrates, which reduces phosphorylation and stabilizes kinetochore microtubules.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2713345/" 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/PMC2713345/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Dan -- Vader, Gerben -- Vromans, Martijn J M -- Lampson, Michael A -- Lens, Susanne M A -- GM083988/GM/NIGMS NIH HHS/ -- R01 GM083988/GM/NIGMS NIH HHS/ -- R01 GM083988-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 6;323(5919):1350-3. doi: 10.1126/science.1167000.

    Description: The "royal disease," a blood disorder transmitted from Queen Victoria to European royal families, is a striking example of X-linked recessive inheritance. Although the disease is widely recognized to be a form of the blood clotting disorder hemophilia, its molecular basis has never been identified, and the royal disease is now likely extinct. We identified the likely disease-causing mutation by applying genomic methodologies (multiplex target amplification and massively parallel sequencing) to historical specimens from the Romanov branch of the royal family. The mutation occurs in F9, a gene on the X chromosome that encodes blood coagulation factor IX, and is predicted to alter RNA splicing and to lead to production of a truncated form of factor IX. Thus, the royal disease is the severe form of hemophilia, also known as hemophilia B or Christmas disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rogaev, Evgeny I -- Grigorenko, Anastasia P -- Faskhutdinova, Gulnaz -- Kittler, Ellen L W -- Moliaka, Yuri K -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):817. doi: 10.1126/science.1180660.

    Description: Amyloid-beta (Abeta) accumulation in the brain extracellular space is a hallmark of Alzheimer's disease. The factors regulating this process are only partly understood. Abeta aggregation is a concentration-dependent process that is likely responsive to changes in brain interstitial fluid (ISF) levels of Abeta. Using in vivo microdialysis in mice, we found that the amount of ISF Abeta correlated with wakefulness. The amount of ISF Abeta also significantly increased during acute sleep deprivation and during orexin infusion, but decreased with infusion of a dual orexin receptor antagonist. Chronic sleep restriction significantly increased, and a dual orexin receptor antagonist decreased, Abeta plaque formation in amyloid precursor protein transgenic mice. Thus, the sleep-wake cycle and orexin may play a role in the pathogenesis of Alzheimer's disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2789838/" 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/PMC2789838/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kang, Jae-Eun -- Lim, Miranda M -- Bateman, Randall J -- Lee, James J -- Smyth, Liam P -- Cirrito, John R -- Fujiki, Nobuhiro -- Nishino, Seiji -- Holtzman, David M -- AG025824/AG/NIA NIH HHS/ -- AG029524/AG/NIA NIH HHS/ -- AG030946/AG/NIA NIH HHS/ -- K01 AG029524/AG/NIA NIH HHS/ -- K01 AG029524-03/AG/NIA NIH HHS/ -- K23 AG030946/AG/NIA NIH HHS/ -- K23 AG030946-03/AG/NIA NIH HHS/ -- MH072525/MH/NIMH NIH HHS/ -- NS065667/NS/NINDS NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- P30 DK056341-09/DK/NIDDK NIH HHS/ -- P30 NS057105/NS/NINDS NIH HHS/ -- P30 NS057105-04/NS/NINDS NIH HHS/ -- P50 AG005681/AG/NIA NIH HHS/ -- R01 AG025824/AG/NIA NIH HHS/ -- R01 AG025824-03/AG/NIA NIH HHS/ -- R01 MH072525/MH/NIMH NIH HHS/ -- R01 MH072525-04/MH/NIMH NIH HHS/ -- R01 NS065667/NS/NINDS NIH HHS/ -- R01 NS065667-02/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):1005-7. doi: 10.1126/science.1180962.

    Description: Speciation often involves the evolution of incompatible gene interactions that cause sterility or lethality in hybrids between populations. These so-called hybrid incompatibilities occur between two or more functionally divergent loci. We show that the nucleoporin 160kDa (Nup160) gene of the fruitfly Drosophila simulans is incompatible with one or more factors on the D. melanogaster X chromosome, causing hybrid lethality. Nup160 encodes a nuclear pore complex protein and shows evidence of adaptive evolution. Furthermore, the protein encoded by Nup160 directly interacts with that of another hybrid lethality gene, Nup96, indicating that at least two lethal hybrid incompatibility genes have evolved as byproducts of divergent coevolution among interacting components of the Drosophila nuclear pore complex.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2826207/" 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/PMC2826207/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tang, Shanwu -- Presgraves, Daven C -- R01 GM079543/GM/NIGMS NIH HHS/ -- R01 GM079543-01A1/GM/NIGMS NIH HHS/ -- R01-GM079543/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):779-82. doi: 10.1126/science.1169123.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Rochester, Rochester, NY 14627, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197064" target="_blank"〉PubMed〈/a〉

    Description: The investigation and study of cancer stem cells (CSCs) have received enormous attention over the past 5 to 10 years but remain topics of considerable controversy. Opinions about the validity of the CSC hypothesis, the biological properties of CSCs, and the relevance of CSCs to cancer therapy differ widely. In the following commentary, we discuss the nature of the debate, the parameters by which CSCs can or cannot be defined, and the identification of new potential therapeutic targets elucidated by considering cancer as a problem in stem cell biology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2873047/" 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/PMC2873047/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosen, Jeffrey M -- Jordan, Craig T -- R01 CA122206/CA/NCI NIH HHS/ -- R01 CA122206-02/CA/NCI NIH HHS/ -- R01-CA122206/CA/NCI NIH HHS/ -- R37 CA016303/CA/NCI NIH HHS/ -- R37 CA016303-36/CA/NCI NIH HHS/ -- R37-CA16303/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jun 26;324(5935):1670-3. doi: 10.1126/science.1171837.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19556499" target="_blank"〉PubMed〈/a〉

    Description: Caloric restriction (CR), without malnutrition, delays aging and extends life span in diverse species; however, its effect on resistance to illness and mortality in primates has not been clearly established. We report findings of a 20-year longitudinal adult-onset CR study in rhesus monkeys aimed at filling this critical gap in aging research. In a population of rhesus macaques maintained at the Wisconsin National Primate Research Center, moderate CR lowered the incidence of aging-related deaths. At the time point reported, 50% of control fed animals survived as compared with 80% of the CR animals. Furthermore, CR delayed the onset of age-associated pathologies. Specifically, CR reduced the incidence of diabetes, cancer, cardiovascular disease, and brain atrophy. These data demonstrate that CR slows aging in a primate species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2812811/" 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/PMC2812811/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Colman, Ricki J -- Anderson, Rozalyn M -- Johnson, Sterling C -- Kastman, Erik K -- Kosmatka, Kristopher J -- Beasley, T Mark -- Allison, David B -- Cruzen, Christina -- Simmons, Heather A -- Kemnitz, Joseph W -- Weindruch, Richard -- P01 AG-11915/AG/NIA NIH HHS/ -- P01 AG011915/AG/NIA NIH HHS/ -- P01 AG011915-11A29002/AG/NIA NIH HHS/ -- P51 RR000167/RR/NCRR NIH HHS/ -- RR020141-01/RR/NCRR NIH HHS/ -- RR15459-01/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 10;325(5937):201-4. doi: 10.1126/science.1173635.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wisconsin National Primate Research Center, University of Wisconsin, Madison, WI 53715, USA. rcolman@primate.wisc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19590001" target="_blank"〉PubMed〈/a〉

    Description: Despite the costs of mating, females of most taxa mate with multiple males. Polyandrous females are hypothesized to gain genetic benefits for their offspring, but this assumes paternity bias favoring male genotypes that enhance offspring viability. We determined net male genetic effects on female and offspring fitness in a seed beetle and then tested whether fertilization success was biased in favor of high-quality male genotypes in double mating experiments. Contrary to expectations, high-quality male genotypes consistently had a lower postmating fertilization success in two independent assays. Our results imply that sexually antagonistic adaptations have a major and unappreciated influence on male postmating fertilization success. Such genetic variation renders indirect genetic benefits an unlikely driver of the evolution of polyandry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bilde, Trine -- Foged, Anne -- Schilling, Nadia -- Arnqvist, Goran -- New York, N.Y. -- Science. 2009 Jun 26;324(5935):1705-6. doi: 10.1126/science.1171675.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, Evolutionary Biology Centre, University of Uppsala, Norbyvagen 18d, SE - 752 36 Uppsala, Sweden. trine.bilde@biology.au.dk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19556506" target="_blank"〉PubMed〈/a〉

    Description: Male animals of many species deploy conditional reproductive strategies that contain distinct alternative phenotypes. Such facultatively expressed male tactics are assumed to be due to a single developmental threshold mechanism switching between the expression of two alternative phenotypes. However, we discovered a clade of dung beetles that commonly expresses two threshold mechanisms, resulting in three alternative phenotypes (male trimorphism). Once recognized, we found trimorphism in other beetle families that involves different types of male weapons. Evidence that insects assumed to be dimorphic can express three facultative male forms suggests that we need to adjust how we think about animal mating systems and the evolution of conditional strategies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowland, J Mark -- Emlen, Douglas J -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):773-6. doi: 10.1126/science.1167345.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of New Mexico, Albuquerque, NM 87131, USA. rowland@unm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197062" target="_blank"〉PubMed〈/a〉

    Description: Words, grammar, and phonology are linguistically distinct, yet their neural substrates are difficult to distinguish in macroscopic brain regions. We investigated whether they can be separated in time and space at the circuit level using intracranial electrophysiology (ICE), namely by recording local field potentials from populations of neurons using electrodes implanted in language-related brain regions while people read words verbatim or grammatically inflected them (present/past or singular/plural). Neighboring probes within Broca's area revealed distinct neuronal activity for lexical (approximately 200 milliseconds), grammatical (approximately 320 milliseconds), and phonological (approximately 450 milliseconds) processing, identically for nouns and verbs, in a region activated in the same patients and task in functional magnetic resonance imaging. This suggests that a linguistic processing sequence predicted on computational grounds is implemented in the brain in fine-grained spatiotemporally patterned activity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4030760/" 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/PMC4030760/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sahin, Ned T -- Pinker, Steven -- Cash, Sydney S -- Schomer, Donald -- Halgren, Eric -- HD18381/HD/NICHD NIH HHS/ -- NS18741/NS/NINDS NIH HHS/ -- NS44623/NS/NINDS NIH HHS/ -- P41 RR014075/RR/NCRR NIH HHS/ -- P41 RR014075-02/RR/NCRR NIH HHS/ -- P41-RR14075/RR/NCRR NIH HHS/ -- R01 HD018381-18/HD/NICHD NIH HHS/ -- R01 NS018741/NS/NINDS NIH HHS/ -- R01 NS018741-22/NS/NINDS NIH HHS/ -- R01 NS044623/NS/NINDS NIH HHS/ -- R01 NS044623-03/NS/NINDS NIH HHS/ -- T32 MH070328-03/MH/NIMH NIH HHS/ -- T32-MH070328/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 16;326(5951):445-9. doi: 10.1126/science.1174481.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Radiology, University of California-San Diego, La Jolla, CA 92037, USA. sahin@post.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19833971" target="_blank"〉PubMed〈/a〉

    Description: The thiol group of the amino acid cysteine can be modified to regulate protein activity. The Escherichia coli periplasm is an oxidizing environment in which most cysteine residues are involved in disulfide bonds. However, many periplasmic proteins contain single cysteine residues, which are vulnerable to oxidation to sulfenic acids and then irreversibly modified to sulfinic and sulfonic acids. We discovered that DsbG and DsbC, two thioredoxin-related proteins, control the global sulfenic acid content of the periplasm and protect single cysteine residues from oxidation. DsbG interacts with the YbiS protein and, along with DsbC, regulates oxidation of its catalytic cysteine residue. Thus, a potentially widespread mechanism controls sulfenic acid modification in the cellular environment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Depuydt, Matthieu -- Leonard, Stephen E -- Vertommen, Didier -- Denoncin, Katleen -- Morsomme, Pierre -- Wahni, Khadija -- Messens, Joris -- Carroll, Kate S -- Collet, Jean-Francois -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1109-11. doi: 10.1126/science.1179557.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉de Duve Institute, Universite catholique de Louvain, B-1200 Brussels, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965429" target="_blank"〉PubMed〈/a〉

    Description: After the domestication of animals and crops in the Near East some 11,000 years ago, farming had reached much of central Europe by 7500 years before the present. The extent to which these early European farmers were immigrants or descendants of resident hunter-gatherers who had adopted farming has been widely debated. We compared new mitochondrial DNA (mtDNA) sequences from late European hunter-gatherer skeletons with those from early farmers and from modern Europeans. We find large genetic differences between all three groups that cannot be explained by population continuity alone. Most (82%) of the ancient hunter-gatherers share mtDNA types that are relatively rare in central Europeans today. Together, these analyses provide persuasive evidence that the first farmers were not the descendants of local hunter-gatherers but immigrated into central Europe at the onset of the Neolithic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bramanti, B -- Thomas, M G -- Haak, W -- Unterlaender, M -- Jores, P -- Tambets, K -- Antanaitis-Jacobs, I -- Haidle, M N -- Jankauskas, R -- Kind, C-J -- Lueth, F -- Terberger, T -- Hiller, J -- Matsumura, S -- Forster, P -- Burger, J -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):137-40. doi: 10.1126/science.1176869.

    Description: Ten-month-old infants persistently search for a hidden object at its initial hiding place even after observing it being hidden at another location. Recent evidence suggests that communicative cues from the experimenter contribute to the emergence of this perseverative search error. We replicated these results with dogs (Canis familiaris), who also commit more search errors in ostensive-communicative (in 75% of the total trials) than in noncommunicative (39%) or nonsocial (17%) hiding contexts. However, comparative investigations suggest that communicative signals serve different functions for dogs and infants, whereas human-reared wolves (Canis lupus) do not show doglike context-dependent differences of search errors. We propose that shared sensitivity to human communicative signals stems from convergent social evolution of the Homo and the Canis genera.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Topal, Jozsef -- Gergely, Gyorgy -- Erdohegyi, Agnes -- Csibra, Gergely -- Miklosi, Adam -- G9715587/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Sep 4;325(5945):1269-72. doi: 10.1126/science.1176960.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Institute for Psychology, Hungarian Academy of Sciences, 1132 Budapest, Hungary. topaljozsef@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19729660" target="_blank"〉PubMed〈/a〉

    Description: Regeneration of injured neurons can restore function, but most neurons regenerate poorly or not at all. The failure to regenerate in some cases is due to a lack of activation of cell-intrinsic regeneration pathways. These pathways might be targeted for the development of therapies that can restore neuron function after injury or disease. Here, we show that the DLK-1 mitogen-activated protein (MAP) kinase pathway is essential for regeneration in Caenorhabditis elegans motor neurons. Loss of this pathway eliminates regeneration, whereas activating it improves regeneration. Further, these proteins also regulate the later step of growth cone migration. We conclude that after axon injury, activation of this MAP kinase cascade is required to switch the mature neuron from an aplastic state to a state capable of growth.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2729122/" 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/PMC2729122/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hammarlund, Marc -- Nix, Paola -- Hauth, Linda -- Jorgensen, Erik M -- Bastiani, Michael -- 1R21NS060275/NS/NINDS NIH HHS/ -- NS034307/NS/NINDS NIH HHS/ -- R21 NS060275-02/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):802-6. doi: 10.1126/science.1165527.

    Description: Expression of the Escherichia coli tryptophanase operon depends on ribosome stalling during translation of the upstream TnaC leader peptide, a process for which interactions between the TnaC nascent chain and the ribosomal exit tunnel are critical. We determined a 5.8 angstrom-resolution cryo-electron microscopy and single-particle reconstruction of a ribosome stalled during translation of the tnaC leader gene. The nascent chain was extended within the exit tunnel, making contacts with ribosomal components at distinct sites. Upon stalling, two conserved residues within the peptidyltransferase center adopted conformations that preclude binding of release factors. We propose a model whereby interactions within the tunnel are relayed to the peptidyltransferase center to inhibit translation. Moreover, we show that nascent chains adopt distinct conformations within the ribosomal exit tunnel.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2920484/" 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/PMC2920484/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seidelt, Birgit -- Innis, C Axel -- Wilson, Daniel N -- Gartmann, Marco -- Armache, Jean-Paul -- Villa, Elizabeth -- Trabuco, Leonardo G -- Becker, Thomas -- Mielke, Thorsten -- Schulten, Klaus -- Steitz, Thomas A -- Beckmann, Roland -- GM022778/GM/NIGMS NIH HHS/ -- P41 RR005969/RR/NCRR NIH HHS/ -- P41 RR005969-19/RR/NCRR NIH HHS/ -- P41-RR05969/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Dec 4;326(5958):1412-5. doi: 10.1126/science.1177662.

    Description: Horse domestication revolutionized transport, communications, and warfare in prehistory, yet the identification of early domestication processes has been problematic. Here, we present three independent lines of evidence demonstrating domestication in the Eneolithic Botai Culture of Kazakhstan, dating to about 3500 B.C.E. Metrical analysis of horse metacarpals shows that Botai horses resemble Bronze Age domestic horses rather than Paleolithic wild horses from the same region. Pathological characteristics indicate that some Botai horses were bridled, perhaps ridden. Organic residue analysis, using delta13C and deltaD values of fatty acids, reveals processing of mare's milk and carcass products in ceramics, indicating a developed domestic economy encompassing secondary products.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Outram, Alan K -- Stear, Natalie A -- Bendrey, Robin -- Olsen, Sandra -- Kasparov, Alexei -- Zaibert, Victor -- Thorpe, Nick -- Evershed, Richard P -- New York, N.Y. -- Science. 2009 Mar 6;323(5919):1332-5. doi: 10.1126/science.1168594.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Archaeology, University of Exeter, Exeter, EX4 4QE, UK. a.k.outram@ex.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19265018" target="_blank"〉PubMed〈/a〉

    Description: Caloric restriction (CR) protects against aging and disease, but the mechanisms by which this affects mammalian life span are unclear. We show in mice that deletion of ribosomal S6 protein kinase 1 (S6K1), a component of the nutrient-responsive mTOR (mammalian target of rapamycin) signaling pathway, led to increased life span and resistance to age-related pathologies, such as bone, immune, and motor dysfunction and loss of insulin sensitivity. Deletion of S6K1 induced gene expression patterns similar to those seen in CR or with pharmacological activation of adenosine monophosphate (AMP)-activated protein kinase (AMPK), a conserved regulator of the metabolic response to CR. Our results demonstrate that S6K1 influences healthy mammalian life-span and suggest that therapeutic manipulation of S6K1 and AMPK might mimic CR and could provide broad protection against diseases of aging.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Selman, Colin -- Tullet, Jennifer M A -- Wieser, Daniela -- Irvine, Elaine -- Lingard, Steven J -- Choudhury, Agharul I -- Claret, Marc -- Al-Qassab, Hind -- Carmignac, Danielle -- Ramadani, Faruk -- Woods, Angela -- Robinson, Iain C A -- Schuster, Eugene -- Batterham, Rachel L -- Kozma, Sara C -- Thomas, George -- Carling, David -- Okkenhaug, Klaus -- Thornton, Janet M -- Partridge, Linda -- Gems, David -- Withers, Dominic J -- BBS/E/B/0000C236/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/E/B/0000M979/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0800339/Medical Research Council/United Kingdom -- G108/551/Medical Research Council/United Kingdom -- MC_U117531708/Medical Research Council/United Kingdom -- MC_U120027537/Medical Research Council/United Kingdom -- MC_U120097114/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):140-4. doi: 10.1126/science.1177221.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Healthy Ageing, Centre for Diabetes and Endocrinology, Department of Medicine, University College London, London WC1E 6JJ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19797661" target="_blank"〉PubMed〈/a〉

    Description: Adults with Asperger syndrome can understand mental states such as desires and beliefs (mentalizing) when explicitly prompted to do so, despite having impairments in social communication. We directly tested the hypothesis that such individuals nevertheless fail to mentalize spontaneously. To this end, we used an eye-tracking task that has revealed the spontaneous ability to mentalize in typically developing infants. We showed that, like infants, neurotypical adults' (n = 17 participants) eye movements anticipated an actor's behavior on the basis of her false belief. This was not the case for individuals with Asperger syndrome (n = 19). Thus, these individuals do not attribute mental states spontaneously, but they may be able to do so in explicit tasks through compensatory learning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Senju, Atsushi -- Southgate, Victoria -- White, Sarah -- Frith, Uta -- G0701484/Medical Research Council/United Kingdom -- PTA 037-27-0107/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Aug 14;325(5942):883-5. doi: 10.1126/science.1176170.

    Description: The evolution and maintenance of sexual reproduction may involve important tradeoffs because asexual reproduction can double an individual's contribution to the gene pool but reduces diversity. Moreover, in social insects the maintenance of genetic diversity among workers may be important for colony growth and survival. We identified a previously unknown termite breeding system in which both parthenogenesis and sexual reproduction are conditionally used. Queens produce their replacements asexually but use normal sexual reproduction to produce other colony members. These findings show how eusociality can lead to extraordinary reproductive systems and provide important insights into the advantages and disadvantages of sex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsuura, Kenji -- Vargo, Edward L -- Kawatsu, Kazutaka -- Labadie, Paul E -- Nakano, Hiroko -- Yashiro, Toshihisa -- Tsuji, Kazuki -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1687. doi: 10.1126/science.1169702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Insect Ecology, Graduate School of Environmental Science, Okayama University, Okayama 700-8530, Japan. kenjijpn@cc.okayama-u.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19325106" target="_blank"〉PubMed〈/a〉

    Description: The gamma-secretase complex plays a role in Alzheimer's disease and cancer progression. The development of clinically useful inhibitors, however, is complicated by the role of the gamma-secretase complex in regulated intramembrane proteolysis of Notch and other essential proteins. Different gamma-secretase complexes containing different Presenilin or Aph1 protein subunits are present in various tissues. Here we show that these complexes have heterogeneous biochemical and physiological properties. Specific inactivation of the Aph1B gamma-secretase in a mouse Alzheimer's disease model led to improvements of Alzheimer's disease-relevant phenotypic features without any Notch-related side effects. The Aph1B complex contributes to total gamma-secretase activity in the human brain, and thus specific targeting of Aph1B-containing gamma-secretase complexes may help generate less toxic therapies for Alzheimer's disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2740474/" 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/PMC2740474/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Serneels, Lutgarde -- Van Biervliet, Jerome -- Craessaerts, Katleen -- Dejaegere, Tim -- Horre, Katrien -- Van Houtvin, Tine -- Esselmann, Hermann -- Paul, Sabine -- Schafer, Martin K -- Berezovska, Oksana -- Hyman, Bradley T -- Sprangers, Ben -- Sciot, Raf -- Moons, Lieve -- Jucker, Mathias -- Yang, Zhixiang -- May, Patrick C -- Karran, Eric -- Wiltfang, Jens -- D'Hooge, Rudi -- De Strooper, Bart -- AG 13579/AG/NIA NIH HHS/ -- AG026593/AG/NIA NIH HHS/ -- P01 AG015379/AG/NIA NIH HHS/ -- P01 AG015379-110009/AG/NIA NIH HHS/ -- P01AG015379/AG/NIA NIH HHS/ -- R01 AG026593/AG/NIA NIH HHS/ -- R01 AG026593-01A1/AG/NIA NIH HHS/ -- R01AG026593/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2009 May 1;324(5927):639-42. doi: 10.1126/science.1171176.

    Description: Acute exposure to ionizing radiation can cause lethal damage to the gastrointestinal (GI) tract, a condition called the GI syndrome. Whether the target cells affected by radiation to cause the GI syndrome are derived from the epithelium or endothelium and whether the target cells die by apoptosis or other mechanisms are controversial issues. Studying mouse models, we found that selective deletion of the proapoptotic genes Bak1 and Bax from the GI epithelium or from endothelial cells did not protect mice from developing the GI syndrome after sub-total-body gamma irradiation. In contrast, selective deletion of p53 from the GI epithelium, but not from endothelial cells, sensitized irradiated mice to the GI syndrome. Transgenic mice overexpressing p53 in all tissues were protected from the GI syndrome after irradiation. These results suggest that the GI syndrome is caused by the death of GI epithelial cells and that these epithelial cells die by a mechanism that is regulated by p53 but independent of apoptosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2897160/" 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/PMC2897160/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kirsch, David G -- Santiago, Philip M -- di Tomaso, Emmanuelle -- Sullivan, Julie M -- Hou, Wu-Shiun -- Dayton, Talya -- Jeffords, Laura B -- Sodha, Pooja -- Mercer, Kim L -- Cohen, Rhianna -- Takeuchi, Osamu -- Korsmeyer, Stanley J -- Bronson, Roderick T -- Kim, Carla F -- Haigis, Kevin M -- Jain, Rakesh K -- Jacks, Tyler -- K08 CA 114176/CA/NCI NIH HHS/ -- K08 CA114176/CA/NCI NIH HHS/ -- K08 CA114176-05/CA/NCI NIH HHS/ -- P01 CA080124/CA/NCI NIH HHS/ -- P01 CA080124-01A1/CA/NCI NIH HHS/ -- P01 CA80124/CA/NCI NIH HHS/ -- P30 CA014051/CA/NCI NIH HHS/ -- P30 CA014051-38/CA/NCI NIH HHS/ -- P30 DK043351/DK/NIDDK NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- RC1 AI078521/AI/NIAID NIH HHS/ -- RC1 AI078521-01/AI/NIAID NIH HHS/ -- RC1-AI078521/AI/NIAID NIH HHS/ -- U19-AI06775/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jan 29;327(5965):593-6. doi: 10.1126/science.1166202.

    Description: The liver-expressed microRNA-122 (miR-122) is essential for hepatitis C virus (HCV) RNA accumulation in cultured liver cells, but its potential as a target for antiviral intervention has not been assessed. We found that treatment of chronically infected chimpanzees with a locked nucleic acid (LNA)-modified oligonucleotide (SPC3649) complementary to miR-122 leads to long-lasting suppression of HCV viremia, with no evidence of viral resistance or side effects in the treated animals. Furthermore, transcriptome and histological analyses of liver biopsies demonstrated derepression of target mRNAs with miR-122 seed sites, down-regulation of interferon-regulated genes, and improvement of HCV-induced liver pathology. The prolonged virological response to SPC3649 treatment without HCV rebound holds promise of a new antiviral therapy with a high barrier to resistance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3436126/" 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/PMC3436126/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lanford, Robert E -- Hildebrandt-Eriksen, Elisabeth S -- Petri, Andreas -- Persson, Robert -- Lindow, Morten -- Munk, Martin E -- Kauppinen, Sakari -- Orum, Henrik -- C06 RR 12087/RR/NCRR NIH HHS/ -- C06 RR012087/RR/NCRR NIH HHS/ -- C06 RR012087-01/RR/NCRR NIH HHS/ -- P51 RR013986/RR/NCRR NIH HHS/ -- P51 RR13986/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):198-201. doi: 10.1126/science.1178178.

    Description: We report a high-quality draft sequence of the genome of the horse (Equus caballus). The genome is relatively repetitive but has little segmental duplication. Chromosomes appear to have undergone few historical rearrangements: 53% of equine chromosomes show conserved synteny to a single human chromosome. Equine chromosome 11 is shown to have an evolutionary new centromere devoid of centromeric satellite DNA, suggesting that centromeric function may arise before satellite repeat accumulation. Linkage disequilibrium, showing the influences of early domestication of large herds of female horses, is intermediate in length between dog and human, and there is long-range haplotype sharing among breeds.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3785132/" 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/PMC3785132/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wade, C M -- Giulotto, E -- Sigurdsson, S -- Zoli, M -- Gnerre, S -- Imsland, F -- Lear, T L -- Adelson, D L -- Bailey, E -- Bellone, R R -- Blocker, H -- Distl, O -- Edgar, R C -- Garber, M -- Leeb, T -- Mauceli, E -- MacLeod, J N -- Penedo, M C T -- Raison, J M -- Sharpe, T -- Vogel, J -- Andersson, L -- Antczak, D F -- Biagi, T -- Binns, M M -- Chowdhary, B P -- Coleman, S J -- Della Valle, G -- Fryc, S -- Guerin, G -- Hasegawa, T -- Hill, E W -- Jurka, J -- Kiialainen, A -- Lindgren, G -- Liu, J -- Magnani, E -- Mickelson, J R -- Murray, J -- Nergadze, S G -- Onofrio, R -- Pedroni, S -- Piras, M F -- Raudsepp, T -- Rocchi, M -- Roed, K H -- Ryder, O A -- Searle, S -- Skow, L -- Swinburne, J E -- Syvanen, A C -- Tozaki, T -- Valberg, S J -- Vaudin, M -- White, J R -- Zody, M C -- Broad Institute Genome Sequencing Platform -- Broad Institute Whole Genome Assembly Team -- Lander, E S -- Lindblad-Toh, K -- 098051/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):865-7. doi: 10.1126/science.1178158.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute, 7 Cambridge Center, Cambridge, MA 02142, USA. c.wade@usyd.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892987" target="_blank"〉PubMed〈/a〉

    Description: How environmental change affects species abundances depends on both the food web within which species interact and their potential to evolve. Using field experiments, we investigated both ecological and evolutionary responses of pea aphids (Acyrthosiphon pisum), a common agricultural pest, to increased frequency of episodic heat shocks. One predator species ameliorated the decrease in aphid population growth with increasing heat shocks, whereas a second predator did not, with this contrast caused by behavioral differences between predators. We also compared aphid strains with stably inherited differences in heat tolerance caused by bacterial endosymbionts and showed the potential for rapid evolution for heat-shock tolerance. Our results illustrate how ecological and evolutionary complexities should be incorporated into predictions of the consequences of environmental change for species' populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harmon, Jason P -- Moran, Nancy A -- Ives, Anthony R -- New York, N.Y. -- Science. 2009 Mar 6;323(5919):1347-50. doi: 10.1126/science.1167396.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Wisconsin, Madison, WI 53706, USA. jharmon@wisc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19265021" target="_blank"〉PubMed〈/a〉

    Description: Flying animals exhibit remarkable capabilities for both generating maneuvers and stabilizing their course and orientation after perturbation. Here we show that flapping fliers ranging in size from fruit flies to large birds benefit from substantial damping of angular velocity through a passive mechanism termed flapping counter-torque (FCT). Our FCT model predicts that isometrically scaled animals experience similar damping on a per-wingbeat time scale, resulting in similar turning dynamics in wingbeat time regardless of body size. The model also shows how animals may simultaneously specialize in both maneuverability and stability (at the cost of efficiency) and provides a framework for linking morphology, wing kinematics, maneuverability, and flight dynamics across a wide range of flying animals spanning insects, bats, and birds.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hedrick, Tyson L -- Cheng, Bo -- Deng, Xinyan -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):252-5. doi: 10.1126/science.1168431.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA. thedrick@bio.unc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359586" target="_blank"〉PubMed〈/a〉
