    Stimulus specificity of gene expression programs determined by temporal control of IKK activity (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-09-17
    Description: A small number of mammalian signaling pathways mediate a myriad of distinct physiological responses to diverse cellular stimuli. Temporal control of the signaling module that contains IkappaB kinase (IKK), its substrate inhibitor of NF-kappaB (IkappaB), and the key inflammatory transcription factor NF-kappaB can allow for selective gene activation. We have demonstrated that different inflammatory stimuli induce distinct IKK profiles, and we examined the underlying molecular mechanisms. Although tumor necrosis factor-alpha (TNFalpha)-induced IKK activity was rapidly attenuated by negative feedback, lipopolysaccharide (LPS) signaling and LPS-specific gene expression programs were dependent on a cytokine-mediated positive feedback mechanism. Thus, the distinct biological responses to LPS and TNFalpha depend on signaling pathway-specific mechanisms that regulate the temporal profile of IKK activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Werner, Shannon L -- Barken, Derren -- Hoffmann, Alexander -- GM071573/GM/NIGMS NIH HHS/ -- GM72024/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2005 Sep 16;309(5742):1857-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Signaling Systems Laboratory, Department of Chemistry and Biochemistry, 9500 Gilman Drive, Mailcode 0375, La Jolla, CA 92093-0375, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16166517" target="_blank"〉PubMed〈/a〉

    Global biodiversity conservation priorities (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-11
    Description: The location of and threats to biodiversity are distributed unevenly, so prioritization is essential to minimize biodiversity loss. To address this need, biodiversity conservation organizations have proposed nine templates of global priorities over the past decade. Here, we review the concepts, methods, results, impacts, and challenges of these prioritizations of conservation practice within the theoretical irreplaceability/vulnerability framework of systematic conservation planning. Most of the templates prioritize highly irreplaceable regions; some are reactive (prioritizing high vulnerability), and others are proactive (prioritizing low vulnerability). We hope this synthesis improves understanding of these prioritization approaches and that it results in more efficient allocation of geographically flexible conservation funding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brooks, T M -- Mittermeier, R A -- da Fonseca, G A B -- Gerlach, J -- Hoffmann, M -- Lamoreux, J F -- Mittermeier, C G -- Pilgrim, J D -- Rodrigues, A S L -- New York, N.Y. -- Science. 2006 Jul 7;313(5783):58-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Conservation International, 1919 M Street, NW, Washington, DC 20036, USA. t.brooks@conservation.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16825561" target="_blank"〉PubMed〈/a〉

    Genome-scale proteomics reveals Arabidopsis thaliana gene models and proteome dynamics (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-04-26
    Description: We have assembled a proteome map for Arabidopsis thaliana from high-density, organ-specific proteome catalogs that we generated for different organs, developmental stages, and undifferentiated cultured cells. We matched 86,456 unique peptides to 13,029 proteins and provide expression evidence for 57 gene models that are not represented in the TAIR7 protein database. Analysis of the proteome identified organ-specific biomarkers and allowed us to compile an organ-specific set of proteotypic peptides for 4105 proteins to facilitate targeted quantitative proteomics surveys. Quantitative information for the identified proteins was used to establish correlations between transcript and protein accumulation in different plant organs. The Arabidopsis proteome map provides information about genome activity and proteome assembly and is available as a resource for plant systems biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baerenfaller, Katja -- Grossmann, Jonas -- Grobei, Monica A -- Hull, Roger -- Hirsch-Hoffmann, Matthias -- Yalovsky, Shaul -- Zimmermann, Philip -- Grossniklaus, Ueli -- Gruissem, Wilhelm -- Baginsky, Sacha -- New York, N.Y. -- Science. 2008 May 16;320(5878):938-41. doi: 10.1126/science.1157956.

    Fundamental evolutionary limits in ecological traits drive Drosophila species distributions (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-09-05
    Description: Species that are habitat specialists make up much of biodiversity, but the evolutionary factors that limit their distributions have rarely been considered. We show that in Drosophila, narrow and wide ranges of desiccation and cold resistance are closely associated with the distributions of specialist and generalist species, respectively. Furthermore, our data show that narrowly distributed tropical species consistently have low means and low genetic variation for these traits as compared with those of widely distributed species after phylogenetic correction. These results are unrelated to levels of neutral variation. Thus, specialist species may simply lack genetic variation in key traits, limiting their ability to adapt to conditions beyond their current range. We predict that such species are likely to be constrained in their evolutionary responses to future climate changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kellermann, Vanessa -- van Heerwaarden, Belinda -- Sgro, Carla M -- Hoffmann, Ary A -- New York, N.Y. -- Science. 2009 Sep 4;325(5945):1244-6. doi: 10.1126/science.1175443.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Environmental Stress and Adaptation Research, Department of Genetics, University of Melbourne, Parkville, Melbourne 3010, Australia. vanessa.kellermann@biology.au.dk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19729654" target="_blank"〉PubMed〈/a〉
