    Beschreibung: Theory predicts, and recent empirical studies have shown, that the diversity of plant species determines the diversity of associated herbivores and mediates ecosystem processes, such as aboveground net primary productivity (ANPP). However, an often-overlooked component of plant diversity, namely population genotypic diversity, may also have wide-ranging effects on community structure and ecosystem processes. We showed experimentally that increasing population genotypic diversity in a dominant old-field plant species, Solidago altissima, determined arthropod diversity and community structure and increased ANPP. The effects of genotypic diversity on arthropod diversity and ANPP were comparable to the effects of plant species diversity measured in other studies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crutsinger, Gregory M -- Collins, Michael D -- Fordyce, James A -- Gompert, Zachariah -- Nice, Chris C -- Sanders, Nathan J -- New York, N.Y. -- Science. 2006 Aug 18;313(5789):966-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of Tennessee, Knoxville, TN 37996, USA. gcrutsin@utk.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16917062" target="_blank"〉PubMed〈/a〉

    Beschreibung: An ecological community's species diversity tends to erode through time as a result of stochastic extinction, competitive exclusion, and unstable host-enemy dynamics. This erosion of diversity can be prevented over the short term if recruits are highly diverse as a result of preferential recruitment of rare species or, alternatively, if rare species survive preferentially, which increases diversity as the ages of the individuals increase. Here, we present census data from seven New and Old World tropical forest dynamics plots that all show the latter pattern. Within local areas, the trees that survived were as a group more diverse than those that were recruited or those that died. The larger (and therefore on average older) survivors were more diverse within local areas than the smaller survivors. When species were rare in a local area, they had a higher survival rate than when they were common, resulting in enrichment for rare species and increasing diversity with age and size class in these complex ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wills, Christopher -- Harms, Kyle E -- Condit, Richard -- King, David -- Thompson, Jill -- He, Fangliang -- Muller-Landau, Helene C -- Ashton, Peter -- Losos, Elizabeth -- Comita, Liza -- Hubbell, Stephen -- Lafrankie, James -- Bunyavejchewin, Sarayudh -- Dattaraja, H S -- Davies, Stuart -- Esufali, Shameema -- Foster, Robin -- Gunatilleke, Nimal -- Gunatilleke, Savitri -- Hall, Pamela -- Itoh, Akira -- John, Robert -- Kiratiprayoon, Somboon -- de Lao, Suzanne Loo -- Massa, Marie -- Nath, Cheryl -- Noor, Md Nur Supardi -- Kassim, Abdul Rahman -- Sukumar, Raman -- Suresh, Hebbalalu Satyanarayana -- Sun, I-Fang -- Tan, Sylvester -- Yamakura, Takuo -- Zimmerman, Jess -- New York, N.Y. -- Science. 2006 Jan 27;311(5760):527-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biological Sciences, University of California, San Diego, La Jolla, CA 92093-0116, USA. cwills@ucsd.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16439661" target="_blank"〉PubMed〈/a〉

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

    Beschreibung: During embryogenesis, stem cells are set aside to fuel the postnatal hair cycle and repair the epidermis after injury. To define how hair follicle stem cells are specified and maintained in an undifferentiated state, we developed a strategy to isolate and transcriptionally profile embryonic hair progenitors in mice. We identified Lhx2 as a transcription factor positioned downstream of signals necessary to specify hair follicle stem cells, but upstream from signals required to drive activated stem cells to terminally differentiate. Using gain- and loss-of-function studies, we uncovered a role for Lhx2 in maintaining the growth and undifferentiated properties of hair follicle progenitors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2405918/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2405918/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rhee, Horace -- Polak, Lisa -- Fuchs, Elaine -- R01 AR031737/AR/NIAMS NIH HHS/ -- R01 AR031737-24/AR/NIAMS NIH HHS/ -- R01 AR050452/AR/NIAMS NIH HHS/ -- R01 AR050452-04/AR/NIAMS NIH HHS/ -- R01-AR050452/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Jun 30;312(5782):1946-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Rockefeller University, 1230 York Avenue, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16809539" target="_blank"〉PubMed〈/a〉

    Beschreibung: Coral reefs are generally associated with shallow tropical seas; however, recent deep-ocean exploration using advanced acoustics and submersibles has revealed unexpectedly widespread and diverse coral ecosystems in deep waters on continental shelves, slopes, seamounts, and ridge systems around the world. Advances reviewed here include the use of corals as paleoclimatic archives and their biogeological functioning, biodiversity, and biogeography. Threats to these fragile, long-lived, and rich ecosystems are mounting: The impacts of deep-water trawling are already widespread, and effects of ocean acidification are potentially devastating.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, J Murray -- Wheeler, Andrew J -- Freiwald, Andre -- New York, N.Y. -- Science. 2006 Apr 28;312(5773):543-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scottish Association for Marine Science, Dunstaffnage Marine Laboratory, Oban, Argyll, PA37 1QA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16645087" target="_blank"〉PubMed〈/a〉

    Beschreibung: Until recently, northern Bering Sea ecosystems were characterized by extensive seasonal sea ice cover, high water column and sediment carbon production, and tight pelagic-benthic coupling of organic production. Here, we show that these ecosystems are shifting away from these characteristics. Changes in biological communities are contemporaneous with shifts in regional atmospheric and hydrographic forcing. In the past decade, geographic displacement of marine mammal population distributions has coincided with a reduction of benthic prey populations, an increase in pelagic fish, a reduction in sea ice, and an increase in air and ocean temperatures. These changes now observed on the shallow shelf of the northern Bering Sea should be expected to affect a much broader portion of the Pacific-influenced sector of the Arctic Ocean.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grebmeier, Jacqueline M -- Overland, James E -- Moore, Sue E -- Farley, Ed V -- Carmack, Eddy C -- Cooper, Lee W -- Frey, Karen E -- Helle, John H -- McLaughlin, Fiona A -- McNutt, S Lyn -- New York, N.Y. -- Science. 2006 Mar 10;311(5766):1461-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Marine Biogeochemistry and Ecology Group, Department of Ecology and Evolutionary Biology, 10515 Research Drive, Building A, Suite 100, University of Tennessee, Knoxville, TN 37932, USA. jgrebmei@utk.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16527980" target="_blank"〉PubMed〈/a〉

    Beschreibung: Long-distance dispersal (LDD) of plants poses challenges to research because it involves rare events driven by complex and highly stochastic processes. The current surge of renewed interest in LDD, motivated by growing recognition of its critical importance for natural populations and communities and for humanity, promises an improved, quantitatively derived understanding of LDD. To gain deep insights into the patterns, mechanisms, causes, and consequences of LDD, we must look beyond the standard dispersal vectors and the mean trend of the distribution of dispersal distances. "Nonstandard" mechanisms such as extreme climatic events and generalized LDD vectors seem to hold the greatest explanatory power for the drastic deviations from the mean trend, deviations that make the nearly impossible LDD a reality.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nathan, Ran -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):786-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Movement Ecology Laboratory, Department of Evolution, Systematics and Ecology, Alexander Silberman Institute of Life Sciences, Hebrew University of Jerusalem, Givat Ram, 91904 Jerusalem, Israel. rnathan@cc.huji.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902126" target="_blank"〉PubMed〈/a〉

    Beschreibung: Conventional ecological theory predicts that predators affect nutrient cycling by decreasing the abundance or activity of prey. By using a predator-detritivore-detritus food chain in bromeliads, we show that predators can increase nutrient cycling by a previously undescribed, but broadly applicable, mechanism: reducing nutrient export by prey emigration. Contrary to expectations, predation on detritivores increases detrital nitrogen uptake by bromeliads. Predation reduces detritivore emergence and hence export of nitrogen from the system. Detritivores therefore benefit their host plant, but only when predators are present. More generally, our results show that predator loss or extinction can dramatically and unexpectedly affect ecosystem functioning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ngai, Jacqueline T -- Srivastava, Diane S -- New York, N.Y. -- Science. 2006 Nov 10;314(5801):963.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of British Columbia, 6270 University Boulevard, Vancouver, British Columbia V6T 1Z4, Canada. ngai@zoology.ubc.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17095695" target="_blank"〉PubMed〈/a〉

    Beschreibung: Aortic aneurysm and dissection are manifestations of Marfan syndrome (MFS), a disorder caused by mutations in the gene that encodes fibrillin-1. Selected manifestations of MFS reflect excessive signaling by the transforming growth factor-beta (TGF-beta) family of cytokines. We show that aortic aneurysm in a mouse model of MFS is associated with increased TGF-beta signaling and can be prevented by TGF-beta antagonists such as TGF-beta-neutralizing antibody or the angiotensin II type 1 receptor (AT1) blocker, losartan. AT1 antagonism also partially reversed noncardiovascular manifestations of MFS, including impaired alveolar septation. These data suggest that losartan, a drug already in clinical use for hypertension, merits investigation as a therapeutic strategy for patients with MFS and has the potential to prevent the major life-threatening manifestation of this disorder.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1482474/" 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/PMC1482474/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Habashi, Jennifer P -- Judge, Daniel P -- Holm, Tammy M -- Cohn, Ronald D -- Loeys, Bart L -- Cooper, Timothy K -- Myers, Loretha -- Klein, Erin C -- Liu, Guosheng -- Calvi, Carla -- Podowski, Megan -- Neptune, Enid R -- Halushka, Marc K -- Bedja, Djahida -- Gabrielson, Kathleen -- Rifkin, Daniel B -- Carta, Luca -- Ramirez, Francesco -- Huso, David L -- Dietz, Harry C -- K08 HL067056/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 7;312(5770):117-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Pediatrics, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16601194" target="_blank"〉PubMed〈/a〉

    Beschreibung: Cells must amplify external signals to orient and migrate in chemotactic gradient fields. We find that human neutrophils release adenosine triphosphate (ATP) from the leading edge of the cell surface to amplify chemotactic signals and direct cell orientation by feedback through P2Y2 nucleotide receptors. Neutrophils rapidly hydrolyze released ATP to adenosine that then acts via A3-type adenosine receptors, which are recruited to the leading edge, to promote cell migration. Thus, ATP release and autocrine feedback through P2Y2 and A3 receptors provide signal amplification, controlling gradient sensing and migration of neutrophils.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Yu -- Corriden, Ross -- Inoue, Yoshiaki -- Yip, Linda -- Hashiguchi, Naoyuki -- Zinkernagel, Annelies -- Nizet, Victor -- Insel, Paul A -- Junger, Wolfgang G -- GM-60475/GM/NIGMS NIH HHS/ -- GM-66232/GM/NIGMS NIH HHS/ -- PR043034/PR/OCPHP CDC HHS/ -- R01 GM-51477/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1792-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Surgery, University of California San Diego, San Diego, CA 92103, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170310" target="_blank"〉PubMed〈/a〉

    Beschreibung: Mutations in the nuclear structural protein lamin A cause the premature aging syndrome Hutchinson-Gilford progeria (HGPS). Whether lamin A plays any role in normal aging is unknown. We show that the same molecular mechanism responsible for HGPS is active in healthy cells. Cell nuclei from old individuals acquire defects similar to those of HGPS patient cells, including changes in histone modifications and increased DNA damage. Age-related nuclear defects are caused by sporadic use, in healthy individuals, of the same cryptic splice site in lamin A whose constitutive activation causes HGPS. Inhibition of this splice site reverses the nuclear defects associated with aging. These observations implicate lamin A in physiological aging.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1855250/" 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/PMC1855250/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scaffidi, Paola -- Misteli, Tom -- Z01 BC010309-07/BC/NCI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2006 May 19;312(5776):1059-63.

    Beschreibung: The tumor suppressor programmed cell death protein 4 (PDCD4) inhibits the translation initiation factor eIF4A, an RNA helicase that catalyzes the unwinding of secondary structure at the 5' untranslated region (5'UTR) of messenger RNAs (mRNAs). In response to mitogens, PDCD4 was rapidly phosphorylated on Ser67 by the protein kinase S6K1 and subsequently degraded via the ubiquitin ligase SCF(betaTRCP). Expression in cultured cells of a stable PDCD4 mutant that is unable to bind betaTRCP inhibited translation of an mRNA with a structured 5'UTR, resulted in smaller cell size, and slowed down cell cycle progression. We propose that regulated degradation of PDCD4 in response to mitogens allows efficient protein synthesis and consequently cell growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dorrello, N Valerio -- Peschiaroli, Angelo -- Guardavaccaro, Daniele -- Colburn, Nancy H -- Sherman, Nicholas E -- Pagano, Michele -- R01-CA76584/CA/NCI NIH HHS/ -- R01-GM57587/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Oct 20;314(5798):467-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, NYU Cancer Institute, New York University School of Medicine, 550 First Avenue, MSB 599, New York, NY 10016, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17053147" target="_blank"〉PubMed〈/a〉

    Beschreibung: In contrast with macroorganisms, whose geographical ranges are typically restricted, many microbial species appear to have cosmopolitan distributions. This observation has been explained as a consequence of ubiquitous dispersal caused by the enormous population sizes of microbial species. Recently, this "everything is everywhere, but, the environment selects" theory has been challenged by the detection of considerable regional genetic variability within microbial morphospecies. We demonstrate that, contrary to what is expected under ubiquitous dispersal, evidence of regional-scale metacommunity processes can be detected in microbial morphospecies. Our results imply that the microbial and macrobial world are structured by analogous processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Telford, Richard J -- Vandvik, Vigdis -- Birks, H J B -- New York, N.Y. -- Science. 2006 May 19;312(5776):1015.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bjerknes Centre for Climate Research, Allegaten 55, N-5007 Bergen, Norway. richard.telford@bjerknes.uib.no〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16709777" target="_blank"〉PubMed〈/a〉

    Beschreibung: IRAK-4 is a protein kinase that is pivotal in mediating signals for innate immune responses. Here, we report that IRAK-4 signaling is also essential for eliciting adaptive immune responses. Thus, in the absence of IRAK-4, in vivo T cell responses were significantly impaired. Upon T cell receptor stimulation, IRAK-4 is recruited to T cell lipid rafts, where it induces downstream signals, including protein kinase C activation through the association with Zap70. This signaling pathway was found to be required for optimal activation of nuclear factor kappaB. Our findings suggest that T cells use this critical regulator of innate immunity for the development of acquired immunity, suggesting that IRAK-4 may be involved in direct signal cross talk between the two systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suzuki, Nobutaka -- Suzuki, Shinobu -- Millar, Douglas G -- Unno, Midori -- Hara, Hiromitsu -- Calzascia, Thomas -- Yamasaki, Sho -- Yokosuka, Tadashi -- Chen, Nien-Jung -- Elford, Alisha R -- Suzuki, Jun-Ichiro -- Takeuchi, Arata -- Mirtsos, Christine -- Bouchard, Denis -- Ohashi, Pamela S -- Yeh, Wen-Chen -- Saito, Takashi -- New York, N.Y. -- Science. 2006 Mar 31;311(5769):1927-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Cell Signaling, RIKEN Research Center for Allergy and Immunology, 1-7-22 Suehiro-cho, Tsurumi-ku, Yokohama City, Kanagawa 230-0045, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16574867" target="_blank"〉PubMed〈/a〉

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

    Beschreibung: The inflammatory bowel diseases Crohn's disease and ulcerative colitis are common, chronic disorders that cause abdominal pain, diarrhea, and gastrointestinal bleeding. To identify genetic factors that might contribute to these disorders, we performed a genome-wide association study. We found a highly significant association between Crohn's disease and the IL23R gene on chromosome 1p31, which encodes a subunit of the receptor for the proinflammatory cytokine interleukin-23. An uncommon coding variant (rs11209026, c.1142G〉A, p.Arg381Gln) confers strong protection against Crohn's disease, and additional noncoding IL23R variants are independently associated. Replication studies confirmed IL23R associations in independent cohorts of patients with Crohn's disease or ulcerative colitis. These results and previous studies on the proinflammatory role of IL-23 prioritize this signaling pathway as a therapeutic target in inflammatory bowel disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4410764/" 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/PMC4410764/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duerr, Richard H -- Taylor, Kent D -- Brant, Steven R -- Rioux, John D -- Silverberg, Mark S -- Daly, Mark J -- Steinhart, A Hillary -- Abraham, Clara -- Regueiro, Miguel -- Griffiths, Anne -- Dassopoulos, Themistocles -- Bitton, Alain -- Yang, Huiying -- Targan, Stephan -- Datta, Lisa Wu -- Kistner, Emily O -- Schumm, L Philip -- Lee, Annette T -- Gregersen, Peter K -- Barmada, M Michael -- Rotter, Jerome I -- Nicolae, Dan L -- Cho, Judy H -- DK62413/DK/NIDDK NIH HHS/ -- DK62420/DK/NIDDK NIH HHS/ -- DK62422/DK/NIDDK NIH HHS/ -- DK62423/DK/NIDDK NIH HHS/ -- DK62429/DK/NIDDK NIH HHS/ -- DK62431/DK/NIDDK NIH HHS/ -- DK62432/DK/NIDDK NIH HHS/ -- P30 DK063491/DK/NIDDK NIH HHS/ -- P30 DK063491-019004/DK/NIDDK NIH HHS/ -- P30 DK063491-029004/DK/NIDDK NIH HHS/ -- P30 DK063491-039004/DK/NIDDK NIH HHS/ -- P30 DK063491-049004/DK/NIDDK NIH HHS/ -- U01 DK062420/DK/NIDDK NIH HHS/ -- U01 DK062422/DK/NIDDK NIH HHS/ -- U01 DK062423/DK/NIDDK NIH HHS/ -- U01 DK062429/DK/NIDDK NIH HHS/ -- U01 DK062432/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 1;314(5804):1461-3.

    Beschreibung: Checkpoints are evolutionarily conserved signaling mechanisms that arrest cell division and alter cellular stress resistance in response to DNA damage or stalled replication forks. To study the consequences of loss of checkpoint functions in whole animals, checkpoint genes were inactivated in the nematode C. elegans. We show that checkpoint proteins are not only essential for normal development but also determine adult somatic maintenance. Checkpoint proteins play a role in the survival of postmitotic adult cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2568993/" 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/PMC2568993/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olsen, Anders -- Vantipalli, Maithili C -- Lithgow, Gordon J -- AG21069/AG/NIA NIH HHS/ -- AG22868/AG/NIA NIH HHS/ -- NS050789-01/NS/NINDS NIH HHS/ -- R01 AG021069/AG/NIA NIH HHS/ -- R01 AG021069-04/AG/NIA NIH HHS/ -- R01 AG022868/AG/NIA NIH HHS/ -- R01 AG022868-04/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2006 Jun 2;312(5778):1381-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Buck Institute, 8001 Redwood Boulevard, Novato, CA 94945, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16741121" target="_blank"〉PubMed〈/a〉

    Beschreibung: Old-growth forests have traditionally been considered negligible as carbon sinks because carbon uptake has been thought to be balanced by respiration. We show that the top 20-centimeter soil layer in preserved old-growth forests in southern China accumulated atmospheric carbon at an unexpectedly high average rate of 0.61 megagrams of carbon hectare-1 year-1 from 1979 to 2003. This study suggests that the carbon cycle processes in the belowground system of these forests are changing in response to the changing environment. The result directly challenges the prevailing belief in ecosystem ecology regarding carbon budget in old-growth forests and supports the establishment of a new, nonequilibrium conceptual framework to study soil carbon dynamics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Guoyi -- Liu, Shuguang -- Li, Zhian -- Zhang, Deqiang -- Tang, Xuli -- Zhou, Chuanyan -- Yan, Junhua -- Mo, Jiangming -- New York, N.Y. -- Science. 2006 Dec 1;314(5804):1417.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉South China Botanical Garden, Chinese Academy of Sciences, Guangzhou, 510650, China. gyzhou@scib.ac.cn〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17138894" target="_blank"〉PubMed〈/a〉

    Beschreibung: Norepinephrine (NE) is widely implicated in opiate withdrawal, but much less is known about its role in opiate-induced locomotion and reward. In mice lacking dopamine beta-hydroxylase (DBH), an enzyme critical for NE synthesis, we found that NE was necessary for morphine-induced conditioned place preference (CPP; a measure of reward) and locomotion. These deficits were rescued by systemic NE restoration. Viral restoration of DBH expression in the nucleus tractus solitarius, but not in the locus coeruleus, restored CPP for morphine. Morphine-induced locomotion was partially restored by DBH expression in either brain region. These data suggest that NE signaling by the nucleus tractus solitarius is necessary for morphine reward.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olson, Valerie G -- Heusner, Carrie L -- Bland, Ross J -- During, Matthew J -- Weinshenker, David -- Palmiter, Richard D -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):1017-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484499" target="_blank"〉PubMed〈/a〉

    Beschreibung: The evolution of new combinations of bacterial properties contributes to biodiversity and the emergence of new diseases. We investigated the capacity for bacterial divergence with a chemostat culture of Escherichia coli. A clonal population radiated into more than five phenotypic clusters within 26 days, with multiple variations in global regulation, metabolic strategies, surface properties, and nutrient permeability pathways. Most isolates belonged to a single ecotype, and neither periodic selection events nor ecological competition for a single niche prevented an adaptive radiation with a single resource. The multidirectional exploration of fitness space is an underestimated ingredient to bacterial success even in unstructured environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maharjan, Ram -- Seeto, Shona -- Notley-McRobb, Lucinda -- Ferenci, Thomas -- New York, N.Y. -- Science. 2006 Jul 28;313(5786):514-7.

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

    Beschreibung: The origin and possible antiquity of faunas at deep-sea hydrothermal vents and seeps have been debated since their discovery. We used the fossil record of seep mollusks to show that the living seep genera have significantly longer geologic ranges than the marine mollusks in general, but have ranges similar to those of deep-sea taxa, suggesting that seep faunas may be shaped by the factors that drive the evolution of life in the deep sea in general. Our data indicate that deep-sea anoxic/dysoxic events did not affect seep faunas, casting doubt on the suggested anoxic nature and/or global extent of these events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kiel, Steffen -- Little, Crispin T S -- New York, N.Y. -- Science. 2006 Sep 8;313(5792):1429-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Earth and Environment, University of Leeds, Leeds LS2 9JT, UK. steffen.kiel@gmx.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16960004" target="_blank"〉PubMed〈/a〉

    Beschreibung: Transient infection of eukaryotic cells with commensal and extraintestinal pathogenic Escherichia coli of phylogenetic group B2 blocks mitosis and induces megalocytosis. This trait is linked to a widely spread genomic island that encodes giant modular nonribosomal peptide and polyketide synthases. Contact with E. coli expressing this gene cluster causes DNA double-strand breaks and activation of the DNA damage checkpoint pathway, leading to cell cycle arrest and eventually to cell death. Discovery of hybrid peptide-polyketide genotoxins in E. coli will change our view on pathogenesis and commensalism and open new biotechnological applications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nougayrede, Jean-Philippe -- Homburg, Stefan -- Taieb, Frederic -- Boury, Michele -- Brzuszkiewicz, Elzbieta -- Gottschalk, Gerhard -- Buchrieser, Carmen -- Hacker, Jorg -- Dobrindt, Ulrich -- Oswald, Eric -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):848-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INRA, UMR1225, Ecole Nationale Veterinaire de Toulouse, Toulouse F-31076, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902142" target="_blank"〉PubMed〈/a〉

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

    Beschreibung: Harvesting threatens many vertebrate species, yet few whole-system manipulations have been conducted to predict the consequences of vertebrate losses on ecosystem function. Here, we show that a harvested migratory detrital-feeding fish (Prochilodontidae: Prochilodus mariae) modulates carbon flow and ecosystem metabolism. Natural declines in and experimental removal of Prochilodus decreased downstream transport of organic carbon and increased primary production and respiration. Thus, besides its economic value, Prochilodus is a critical ecological component of South American rivers. Lack of functional redundancy for this species highlights the importance of individual species and, contrary to theory, suggests that losing one species from lower trophic levels can affect ecosystem functioning even in species-rich ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taylor, Brad W -- Flecker, Alexander S -- Hall, Robert O Jr -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):833-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology and Physiology, University of Wyoming, Laramie, WY 82071, USA. brad.taylor@dartmouth.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902137" target="_blank"〉PubMed〈/a〉

    Beschreibung: Plants may "eavesdrop" on volatile organic compounds (VOCs) released by herbivore-attacked neighbors to activate defenses before being attacked themselves. Transcriptome and signal cascade analyses of VOC-exposed plants suggest that plants eavesdrop to prime direct and indirect defenses and to hone competitive abilities. Advances in research on VOC biosynthesis and perception have facilitated the production of plants that are genetically "deaf" to particular VOCs or "mute" in elements of their volatile vocabulary. Such plants, together with advances in VOC analytical instrumentation, will allow researchers to determine whether fluency enhances the fitness of plants in natural communities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baldwin, Ian T -- Halitschke, Rayko -- Paschold, Anja -- von Dahl, Caroline C -- Preston, Catherine A -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):812-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Ecology, Max Planck Institute for Chemical Ecology, Hans Knoll Strasse 8, Jena 07745, Germany. baldwin@ice.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469918" target="_blank"〉PubMed〈/a〉

    Beschreibung: A methanogenic archaeon isolated from deep-sea hydrothermal vent fluid was found to reduce N(2) to NH(3) at up to 92 degrees C, which is 28 degrees C higher than the current upper temperature limit of biological nitrogen fixation. The 16S ribosomal RNA gene of the hyperthermophilic nitrogen fixer, designated FS406-22, was 99% similar to that of non-nitrogen fixing Methanocaldococcus jannaschii DSM 2661. At its optimal growth temperature of 90 degrees C, FS406-22 incorporated (15)N(2) and expressed nifH messenger RNA. This increase in the temperature limit of nitrogen fixation could reveal a broader range of conditions for life in the subseafloor biosphere and other nitrogen-limited ecosystems than previously estimated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mehta, Mausmi P -- Baross, John A -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1783-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Oceanography, University of Washington, Seattle, WA 98195, USA. mausmi@alum.mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170307" target="_blank"〉PubMed〈/a〉

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

    Beschreibung: It is currently unclear whether observed pelagic ecosystem responses to ocean warming, such as a mid-1970s change in the eastern North Pacific, depart from typical ocean variability. We report variations in planktonic foraminifera from varved sediments off southern California spanning the past 1400 years. Increasing abundances of tropical/subtropical species throughout the 20th century reflect a warming trend superimposed on decadal-scale fluctuations. Decreasing abundances of temperate/subpolar species in the late 20th century indicate a deep, penetrative warming not observed in previous centuries. These results imply that 20th-century warming, apparently anthropogenic, has already affected lower trophic levels of the California Current.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Field, David B -- Baumgartner, Timothy R -- Charles, Christopher D -- Ferreira-Bartrina, Vicente -- Ohman, Mark D -- New York, N.Y. -- Science. 2006 Jan 6;311(5757):63-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scripps Institution of Oceanography, University of California, San Diego, La Jolla, CA 92093, USA. dfield@mbari.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16400144" target="_blank"〉PubMed〈/a〉

    Beschreibung: The function of cyclin-dependent kinase 2 (CDK2) is often abolished after DNA damage. The inhibition of CDK2 plays a central role in DNA damage-induced cell cycle arrest and DNA repair. However, whether CDK2 also influences the survival of cells under genotoxic stress is unknown. Forkhead box O (FOXO) transcription factors are emerging as key regulators of cell survival. CDK2 specifically phosphorylated FOXO1 at serine-249 (Ser249) in vitro and in vivo. Phosphorylation of Ser249 resulted in cytoplasmic localization and inhibition of FOXO1. This phosphorylation was abrogated upon DNA damage through the cell cycle checkpoint pathway that is dependent on the protein kinases Chk1 and Chk2. Moreover, silencing of FOXO1 by small interfering RNA diminished DNA damage-induced death in both p53-deficient and p53-proficient cells. This effect was reversed by restored expression of FOXO1 in a manner depending on phosphorylation of Ser249. Functional interaction between CDK2 and FOXO1 provides a mechanism that regulates apoptotic cell death after DNA strand breakage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Haojie -- Regan, Kevin M -- Lou, Zhenkun -- Chen, Junjie -- Tindall, Donald J -- CA91956/CA/NCI NIH HHS/ -- DK60920/DK/NIDDK NIH HHS/ -- DK65236/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2006 Oct 13;314(5797):294-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Mayo Clinic College of Medicine, Rochester, MN 55905, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17038621" target="_blank"〉PubMed〈/a〉

    Beschreibung: B cells recognize foreign antigens by virtue of cell surface immunoglobulin receptors and are most effectively activated by membrane-bound ligands. Here, we show that in the early stages of this process, B cells exhibit a two-phase response in which they first spread over the antigen-bearing membrane and then contract, thereby collecting bound antigen into a central aggregate. The extent of this response, which is both signaling- and actin-dependent, determines the quantity of antigen accumulated and hence the degree of B cell activation. Brownian dynamic simulations reproduce essential features of the antigen collection process and suggest a possible basis for affinity discrimination. We propose that dynamic spreading is an important step of the immune response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fleire, S J -- Goldman, J P -- Carrasco, Y R -- Weber, M -- Bray, D -- Batista, F D -- G64713/PHS HHS/ -- New York, N.Y. -- Science. 2006 May 5;312(5774):738-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lymphocyte Interaction Laboratory, London Research Institute, Cancer Research UK, 44 Lincoln's Inn Fields, London, WC2A 3PX, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16675699" target="_blank"〉PubMed〈/a〉

    Beschreibung: Dispersal is often risky to the individual, yet the long-term survival of populations depends on having a sufficient number of individuals that move, find each other, and locate suitable breeding habitats. This tension has consequences that rarely meet our conservation or management goals. This is particularly true in changing environments, which makes the study of dispersal urgently topical in a world plagued with habitat loss, climate change, and species introductions. Despite the difficulty of tracking mobile individuals over potentially vast ranges, recent research has revealed a multitude of ways in which dispersal evolution can either constrain, or accelerate, species' responses to environmental changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kokko, Hanna -- Lopez-Sepulcre, Andres -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):789-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Ecological and Evolutionary Dynamics, Department of Biological and Environmental Science, University of Helsinki, Post Office Box 65 (Viikinkaari 1), FIN-00014 Helsinki, Finland. hanna.kokko@helsinki.fi〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902127" target="_blank"〉PubMed〈/a〉

    Beschreibung: Fisheries have removed at least 50 million tons of tuna and other top-level predators from the Pacific Ocean pelagic ecosystem since 1950, leading to concerns about a catastrophic reduction in population biomass and the collapse of oceanic food chains. We analyzed all available data from Pacific tuna fisheries for 1950-2004 to provide comprehensive estimates of fishery impacts on population biomass and size structure. Current biomass ranges among species from 36 to 91% of the biomass predicted in the absence of fishing, a level consistent with or higher than standard fisheries management targets. Fish larger than 175 centimeters fork length have decreased from 5% to approximately 1% of the total population. The trophic level of the catch has decreased slightly, but there is no detectable decrease in the trophic level of the population. These results indicate substantial, though not catastrophic, impacts of fisheries on these top-level predators and minor impacts on the ecosystem in the Pacific Ocean.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sibert, John -- Hampton, John -- Kleiber, Pierre -- Maunder, Mark -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1773-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Joint Institute for Marine and Atmospheric Research, University of Hawaii, Honolulu, HI 96822, USA. sibert@hawaii.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170304" target="_blank"〉PubMed〈/a〉

    Beschreibung: The Arabidopsis CLAVATA3 (CLV3) gene encodes a stem cell-specific protein presumed to be a precursor of a secreted peptide hormone. Matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS) applied to in situ Arabidopsis tissues determined the structure of a modified 12-amino acid peptide (MCLV3), which was derived from a conserved motif in the CLV3 sequence. Synthetic MCLV3 induced shoot and root meristem consumption as cells differentiated into other organs, displaying the typical phenotype of transgenic plants overexpressing CLV3. These results suggest that the functional peptide of CLV3 is MCLV3.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kondo, Tatsuhiko -- Sawa, Shinichiro -- Kinoshita, Atsuko -- Mizuno, Satoko -- Kakimoto, Tatsuo -- Fukuda, Hiroo -- Sakagami, Youji -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):845-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate School of Bio-Agricultural Sciences, Nagoya University, Chikusa, Nagoya, 464-8601, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902141" target="_blank"〉PubMed〈/a〉

    Beschreibung: Inflammation and trauma lead to enhanced pain sensitivity (hyperalgesia), which is in part due to altered sensory processing in the spinal cord. The synaptic hypothesis of hyperalgesia, which postulates that hyperalgesia is induced by the activity-dependent long-term potentiation (LTP) in the spinal cord, has been challenged, because in previous studies of pain pathways, LTP was experimentally induced by nerve stimulation at high frequencies ( approximately 100 hertz). This does not, however, resemble the real low-frequency afferent barrage that occurs during inflammation. We identified a synaptic amplifier at the origin of an ascending pain pathway that is switched-on by low-level activity in nociceptive nerve fibers. This model integrates known signal transduction pathways of hyperalgesia without contradiction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ikeda, Hiroshi -- Stark, Johanna -- Fischer, Harald -- Wagner, Matthias -- Drdla, Ruth -- Jager, Tino -- Sandkuhler, Jurgen -- P 18129/Austrian Science Fund FWF/Austria -- New York, N.Y. -- Science. 2006 Jun 16;312(5780):1659-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurophysiology, Center for Brain Research, Medical University of Vienna, Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16778058" target="_blank"〉PubMed〈/a〉

    Beschreibung: Ciona is an emerging model system for elucidating gene networks in development. Comprehensive in situ hybridization assays have identified 76 regulatory genes with localized expression patterns in the early embryo, at the time when naive blastomeres are determined to follow specific cell fates. Systematic gene disruption assays provided more than 3000 combinations of gene expression profiles in mutant backgrounds. Deduced gene circuit diagrams describing the formation of larval tissues were computationally visualized. These diagrams constitute a blueprint for the Ciona embryo and provide a foundation for understanding the evolutionary origins of the chordate body plan.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Imai, Kaoru S -- Levine, Michael -- Satoh, Nori -- Satou, Yutaka -- New York, N.Y. -- Science. 2006 May 26;312(5777):1183-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, Graduate School of Science, Kyoto University, Sakyo-ku, Kyoto, 606-8502, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16728634" target="_blank"〉PubMed〈/a〉

    Beschreibung: Invasive species may precipitate evolutionary change in invaded communities. In southern New England (USA) the invasive Asian shore crab, Hemigrapsus sanguineus, preys on mussels (Mytlius edulis), but the crab has not yet invaded northern New England. We show that southern New England mussels express inducible shell thickening when exposed to waterborne cues from Hemigrapsus, whereas naive northern mussel populations do not respond. Yet, both populations thicken their shells in response to a long-established crab, Carcinus maenas. Our findings are consistent with the rapid evolution of an inducible morphological response to Hemigrapsus within 15 years of its introduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Freeman, Aaren S -- Byers, James E -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):831-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Zoology Department, Rudman Hall, University of New Hampshire, Durham, NH 03824, USA. afreeman@cisunix.unh.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902136" target="_blank"〉PubMed〈/a〉

    Beschreibung: Mutations in gld-1 cause lethal germline tumors in the nematode Caenorhabditis elegans. We find that a wide variety of mutations that extend C. elegans' life span confer resistance to these tumors. The long life spans of daf-2/insulin-receptor mutants were not shortened at all by gld-1 mutations; we attribute this finding to decreased cell division and increased DAF-16/p53-dependent apoptosis within the tumors. Mutations that increase life span by restricting food intake or inhibiting respiration did not affect apoptosis but reduced tumor cell division. Unexpectedly, none of these longevity mutations affected mitosis in normal germlines; this finding suggests that cellular changes that lead to longevity preferentially antagonize tumor cell growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pinkston, Julie M -- Garigan, Delia -- Hansen, Malene -- Kenyon, Cynthia -- AG000278/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2006 Aug 18;313(5789):971-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and 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/16917064" target="_blank"〉PubMed〈/a〉

    Beschreibung: Innate immunity against bacterial and fungal pathogens is mediated by Toll and immune deficiency (Imd) pathways, but little is known about the antiviral response in Drosophila. Here, we demonstrate that an RNA interference pathway protects adult flies from infection by two evolutionarily diverse viruses. Our work also describes a molecular framework for the viral immunity, in which viral double-stranded RNA produced during infection acts as the pathogen trigger whereas Drosophila Dicer-2 and Argonaute-2 act as host sensor and effector, respectively. These findings establish a Drosophila model for studying the innate immunity against viruses in animals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1509097/" 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/PMC1509097/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Xiao-Hong -- Aliyari, Roghiyh -- Li, Wan-Xiang -- Li, Hong-Wei -- Kim, Kevin -- Carthew, Richard -- Atkinson, Peter -- Ding, Shou-Wei -- AI052447/AI/NIAID NIH HHS/ -- R01 AI052447/AI/NIAID NIH HHS/ -- R01 GM068743/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):452-4.

    Beschreibung: Likelihood analyses of 1176 fossil assemblages of marine organisms from Phanerozoic (i.e., Cambrian to Recent) assemblages indicate a shift in typical relative-abundance distributions after the Paleozoic. Ecological theory associated with these abundance distributions implies that complex ecosystems are far more common among Meso-Cenozoic assemblages than among the Paleozoic assemblages that preceded them. This transition coincides not with any major change in the way fossils are preserved or collected but with a shift from communities dominated by sessile epifaunal suspension feeders to communities with elevated diversities of mobile and infaunal taxa. This suggests that the end-Permian extinction permanently altered prevailing marine ecosystem structure and precipitated high levels of ecological complexity and alpha diversity in the Meso-Cenozoic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wagner, Peter J -- Kosnik, Matthew A -- Lidgard, Scott -- New York, N.Y. -- Science. 2006 Nov 24;314(5803):1289-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geology, Field Museum of Natural History, 1400 South Lake Shore Drive, Chicago, IL 60605, USA. pwagner@fmnh.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17124319" target="_blank"〉PubMed〈/a〉

    Beschreibung: We found an extraordinary level of bacterial biodiversity in the tree leaf canopy of a tropical Atlantic forest by using culture-independent molecular methods. Our survey suggests that each tree species selects for a distinct microbial community. Analysis of the bacterial 16S ribosomal RNA gene sequences revealed that about 97% of the bacteria were unknown species and that the phyllosphere of any one tree species carries at least 95 to 671 bacterial species. The tree canopies of tropical forests likely represent a large reservoir of unexplored microbial diversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lambais, M R -- Crowley, D E -- Cury, J C -- Bull, R C -- Rodrigues, R R -- New York, N.Y. -- Science. 2006 Jun 30;312(5782):1917.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Soils and Soil Science, University of Sao Paulo, Piracicaba, Sao Paulo, Brazil. mlambais@esalq.usp.br〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16809531" target="_blank"〉PubMed〈/a〉

    Beschreibung: Prochlorococcus ecotypes are a useful system for exploring the origin and function of diversity among closely related microbes. The genetic variability between phenotypically distinct strains that differ by less that 1% in 16S ribosomal RNA sequences occurs mostly in genomic islands. Island genes appear to have been acquired in part by phage-mediated lateral gene transfer, and some are differentially expressed under light and nutrient stress. Furthermore, genome fragments directly recovered from ocean ecosystems indicate that these islands are variable among cooccurring Prochlorococcus cells. Genomic islands in this free-living photoautotroph share features with pathogenicity islands of parasitic bacteria, suggesting a general mechanism for niche differentiation in microbial species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coleman, Maureen L -- Sullivan, Matthew B -- Martiny, Adam C -- Steglich, Claudia -- Barry, Kerrie -- Delong, Edward F -- Chisholm, Sallie W -- New York, N.Y. -- Science. 2006 Mar 24;311(5768):1768-70.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts Institute of Technology, Department of Civil and Environmental Engineering, 15 Vassar Street, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16556843" target="_blank"〉PubMed〈/a〉

    Beschreibung: Yersinia species use a variety of type III effector proteins to target eukaryotic signaling systems. The effector YopJ inhibits mitogen-activated protein kinase (MAPK) and the nuclear factor kappaB (NFkappaB) signaling pathways used in innate immune response by preventing activation of the family of MAPK kinases (MAPKK). We show that YopJ acted as an acetyltransferase, using acetyl-coenzyme A (CoA) to modify the critical serine and threonine residues in the activation loop of MAPKK6 and thereby blocking phosphorylation. The acetylation on MAPKK6 directly competed with phosphorylation, preventing activation of the modified protein. This covalent modification may be used as a general regulatory mechanism in biological signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mukherjee, Sohini -- Keitany, Gladys -- Li, Yan -- Wang, Yong -- Ball, Haydn L -- Goldsmith, Elizabeth J -- Orth, Kim -- R01-AI056404/AI/NIAID NIH HHS/ -- R21-DK072134/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2006 May 26;312(5777):1211-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, University of Texas Southwestern Medical Center, Dallas, TX 75390, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16728640" target="_blank"〉PubMed〈/a〉

    Beschreibung: Despite widespread concern about declines in pollination services, little is known about the patterns of change in most pollinator assemblages. By studying bee and hoverfly assemblages in Britain and the Netherlands, we found evidence of declines (pre-versus post-1980) in local bee diversity in both countries; however, divergent trends were observed in hoverflies. Depending on the assemblage and location, pollinator declines were most frequent in habitat and flower specialists, in univoltine species, and/or in nonmigrants. In conjunction with this evidence, outcrossing plant species that are reliant on the declining pollinators have themselves declined relative to other plant species. Taken together, these findings strongly suggest a causal connection between local extinctions of functionally linked plant and pollinator species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biesmeijer, J C -- Roberts, S P M -- Reemer, M -- Ohlemuller, R -- Edwards, M -- Peeters, T -- Schaffers, A P -- Potts, S G -- Kleukers, R -- Thomas, C D -- Settele, J -- Kunin, W E -- New York, N.Y. -- Science. 2006 Jul 21;313(5785):351-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Integrative and Comparative Biology and Earth and Biosphere Institute, University of Leeds, Leeds, LS2 9JT, UK. j.c.biesmeijer@leeds.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16857940" target="_blank"〉PubMed〈/a〉

    Beschreibung: The interface between an infectious agent and its host represents the ultimate battleground for survival: The microbe must secure a niche for replication, whereas the host must limit the pathogen's advance. Among the host's arsenal of antimicrobial factors, the type 1 interferons (IFNs) induce potent defense mechanisms against viruses and are key in the host-virus standoff. Viruses have evolved multiple tricks to avoid the immediate antiviral effects of IFNs and, in turn, hosts have adapted use of this innate cytokine system to galvanize multiple additional layers of immune defense. The plasticity that exists in these interactions provides us with a lesson in detente.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garcia-Sastre, Adolfo -- Biron, Christine A -- P01AI52106/AI/NIAID NIH HHS/ -- P01AI58113/AI/NIAID NIH HHS/ -- R01AI46954/AI/NIAID NIH HHS/ -- R01AI55677/AI/NIAID NIH HHS/ -- R01CA41268/CA/NCI NIH HHS/ -- U19AI62623/AI/NIAID NIH HHS/ -- U54AI57158/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2006 May 12;312(5775):879-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Mount Sinai School of Medicine, New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16690858" target="_blank"〉PubMed〈/a〉

    Beschreibung: Prochlorococcus is the numerically dominant phytoplankter in the oligotrophic oceans, accounting for up to half of the photosynthetic biomass and production in some regions. Here, we describe how the abundance of six known ecotypes, which have small subunit ribosomal RNA sequences that differ by less than 3%, changed along local and basin-wide environmental gradients in the Atlantic Ocean. Temperature was significantly correlated with shifts in ecotype abundance, and laboratory experiments confirmed different temperature optima and tolerance ranges for cultured strains. Light, nutrients, and competitor abundances also appeared to play a role in shaping different distributions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, Zackary I -- Zinser, Erik R -- Coe, Allison -- McNulty, Nathan P -- Woodward, E Malcolm S -- Chisholm, Sallie W -- New York, N.Y. -- Science. 2006 Mar 24;311(5768):1737-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Civil and Environmental Engineering, Massachusetts Institute of Technology, 15 Vassar Street 48-419, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16556835" target="_blank"〉PubMed〈/a〉

    Beschreibung: We report the sequence and analysis of the 814-megabase genome of the sea urchin Strongylocentrotus purpuratus, a model for developmental and systems biology. The sequencing strategy combined whole-genome shotgun and bacterial artificial chromosome (BAC) sequences. This use of BAC clones, aided by a pooling strategy, overcame difficulties associated with high heterozygosity of the genome. The genome encodes about 23,300 genes, including many previously thought to be vertebrate innovations or known only outside the deuterostomes. This echinoderm genome provides an evolutionary outgroup for the chordates and yields insights into the evolution of deuterostomes.〈br /〉〈br /〉〈a

    Beschreibung: Most ecological hypotheses about species coexistence hinge on species differences, but quantifying trait differences across species in diverse communities is often unfeasible. We examined the variation of demographic traits using a global tropical forest data set covering 4500 species in 10 large-scale tree inventories. With a hierarchical Bayesian approach, we quantified the distribution of mortality and growth rates of all tree species at each site. This allowed us to test the prediction that demographic differences facilitate species richness, as suggested by the theory that a tradeoff between high growth and high survival allows species to coexist. Contrary to the prediction, the most diverse forests had the least demographic variation. Although demographic differences may foster coexistence, they do not explain any of the 16-fold variation in tree species richness observed across the tropics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Condit, Richard -- Ashton, Peter -- Bunyavejchewin, Sarayudh -- Dattaraja, H S -- Davies, Stuart -- Esufali, Shameema -- Ewango, Corneille -- Foster, Robin -- Gunatilleke, I A U N -- Gunatilleke, C V S -- Hall, Pamela -- Harms, Kyle E -- Hart, Terese -- Hernandez, Consuelo -- Hubbell, Stephen -- Itoh, Akira -- Kiratiprayoon, Somboon -- Lafrankie, James -- de Lao, Suzanne Loo -- Makana, Jean-Remy -- Noor, Md Nur Supardi -- Kassim, Abdul Rahman -- Russo, Sabrina -- Sukumar, Raman -- Samper, Cristian -- Suresh, Hebbalalu S -- Tan, Sylvester -- Thomas, Sean -- Valencia, Renato -- Vallejo, Martha -- Villa, Gorky -- Zillio, Tommaso -- New York, N.Y. -- Science. 2006 Jul 7;313(5783):98-101.

    Beschreibung: The Paleocene-Eocene Thermal Maximum (PETM, approximately 55 million years ago) was an interval of global warming and ocean acidification attributed to rapid release and oxidation of buried carbon. We show that the onset of the PETM coincided with a prominent increase in the origination and extinction of calcareous phytoplankton. Yet major perturbation of the surface-water saturation state across the PETM was not detrimental to the survival of most calcareous nannoplankton taxa and did not impart a calcification or ecological bias to the pattern of evolutionary turnover. Instead, the rate of environmental change appears to have driven turnover, preferentially affecting rare taxa living close to their viable limits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibbs, Samantha J -- Bown, Paul R -- Sessa, Jocelyn A -- Bralower, Timothy J -- Wilson, Paul A -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1770-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Ocean and Earth Sciences, National Oceanography Centre, Southampton, European Way, Southampton, SO14 3ZH, UK. sxg@noc.soton.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170303" target="_blank"〉PubMed〈/a〉

    Beschreibung: By using data collected during a continuous circumnavigation of the Southern Hemisphere, we observed clear patterns in the population-genetic structure of Prochlorococcus, the most abundant photosynthetic organism on Earth, between and within the three Southern Subtropical Gyres. The same mechanisms that were previously invoked to account for the vertical distribution of ecotypes at local scales accounted for the global (horizontal) patterns we observed. Basin-scale and seasonal variations in the structure and strength of vertical stratification provide a basis for understanding large-scale horizontal distribution in genetic and physiological traits of Prochlorococcus, and perhaps of marine microbial communities in general.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bouman, Heather A -- Ulloa, Osvaldo -- Scanlan, David J -- Zwirglmaier, Katrin -- Li, William K W -- Platt, Trevor -- Stuart, Venetia -- Barlow, Ray -- Leth, Ole -- Clementson, Lesley -- Lutz, Vivian -- Fukasawa, Masao -- Watanabe, Shuichi -- Sathyendranath, Shubha -- New York, N.Y. -- Science. 2006 May 12;312(5775):918-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratorio de Procesos Oceanograficos y Clima, Departamento de Oceanografia, and Centro de Investigacion Oceanografica en el Pacifico Sur-Oriental, Universidad de Concepcion, Casilla 160-C, Concepcion, Chile. heather@profc.udec.cl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16690867" target="_blank"〉PubMed〈/a〉

    Beschreibung: Sleep is a vital, evolutionarily conserved phenomenon, whose function is unclear. Although mounting evidence supports a role for sleep in the consolidation of memories, until now, a molecular connection between sleep, plasticity, and memory formation has been difficult to demonstrate. We establish Drosophila as a model to investigate this relation and demonstrate that the intensity and/or complexity of prior social experience stably modifies sleep need and architecture. Furthermore, this experience-dependent plasticity in sleep need is subserved by the dopaminergic and adenosine 3',5'-monophosphate signaling pathways and a particular subset of 17 long-term memory genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ganguly-Fitzgerald, Indrani -- Donlea, Jeff -- Shaw, Paul J -- R01-NS051305-01A1/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 22;313(5794):1775-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurosciences Institute, 10640 John Jay Hopkins Drive, San Diego, CA 92101, USA. transposase@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16990546" target="_blank"〉PubMed〈/a〉
