    Bod1 regulates protein phosphatase 2A at mitotic kinetochores (2013)
    Springer Nature
    Details
    Publication Date: 2013-10-27
    Description: Article PP2A-B56 regulates the stability of kinetochore-microtubule attachments by dephosphorylating several kinetochore proteins. Porter et al . identify Bod1 as a specific inhibitor of PP2A-B56 phosphatase activity and show that this activity is required for proper chromosome alignment during mitosis.

    Estuarine and early-marine survival of transported and in-river migrant Snake River spring Chinook salmon smolts (2012)
    Springer Nature

    Publication Date: 2012-07-09
    Description: Estuarine and early-marine survival of transported and in-river migrant Snake River spring Chinook salmon smolts Scientific Reports 2, 11062012 doi: 10.1038/srep00448 Erin L. Rechisky David W. Welch Aswea D. Porter Melinda C. Jacobs-Scott Paul M. Winchell John L. McKern Many juvenile Snake River Chinook salmon are transported downriver to avoid hydroelectric dams in the Columbia River basin. As mortality to the final dam is ∼50%, transported fish should return as adults at roughly double the rate of nontransported fish; however, the benefit of transportation has not been realized consistently. “Delayed” mortality caused by transportation-induced stress is one hypothesis to explain reduced returns of transported fish. Differential timing of ocean entry is another. We used a large-scale acoustic telemetry array to test whether survival of transported juvenile spring Chinook is reduced relative to in-river migrant control groups after synchronizing ocean entry timing. During the initial 750 km, 1 month long migration after release, we found no evidence of decreased estuarine or ocean survival of transported groups; therefore, decreased survival to adulthood for transported Chinook is likely caused by factors other than delayed effects of transportation, such as earlier ocean entry.

    Suppression of thermal conductivity by rattling modes in thermoelectric sodium cobaltate (2013)
    Springer Nature
    Details
    Publication Date: 2013-10-24
    Description: Nature Materials 12, 1028 (2013). doi:10.1038/nmat3739 Authors: D. J. Voneshen, K. Refson, E. Borissenko, M. Krisch, A. Bosak, A. Piovano, E. Cemal, M. Enderle, M. J. Gutmann, M. Hoesch, M. Roger, L. Gannon, A. T. Boothroyd, S. Uthayakumar, D. G. Porter & J. P. Goff The need for both high electrical conductivity and low thermal conductivity creates a design conflict for thermoelectric systems, leading to the consideration of materials with complicated crystal structures. Rattling of ions in cages results in low thermal conductivity, but understanding the mechanism through studies of the phonon dispersion using momentum-resolved spectroscopy is made difficult by the complexity of the unit cells. We have performed inelastic X-ray and neutron scattering experiments that are in remarkable agreement with our first-principles density-functional calculations of the phonon dispersion for thermoelectric Na0.8CoO2, which has a large-period superstructure. We have directly observed an Einstein-like rattling mode at low energy, involving large anharmonic displacements of the sodium ions inside multi-vacancy clusters. These rattling modes suppress the thermal conductivity by a factor of six compared with vacancy-free NaCoO2. Our results will guide the design of the next generation of materials for applications in solid-state refrigerators and power recovery.

    The landscape of somatic copy-number alteration across human cancers (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-02-19
    Description: A powerful way to discover key genes with causal roles in oncogenesis is to identify genomic regions that undergo frequent alteration in human cancers. Here we present high-resolution analyses of somatic copy-number alterations (SCNAs) from 3,131 cancer specimens, belonging largely to 26 histological types. We identify 158 regions of focal SCNA that are altered at significant frequency across several cancer types, of which 122 cannot be explained by the presence of a known cancer target gene located within these regions. Several gene families are enriched among these regions of focal SCNA, including the BCL2 family of apoptosis regulators and the NF-kappaBeta pathway. We show that cancer cells containing amplifications surrounding the MCL1 and BCL2L1 anti-apoptotic genes depend on the expression of these genes for survival. Finally, we demonstrate that a large majority of SCNAs identified in individual cancer types are present in several cancer types.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2826709/" 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/PMC2826709/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beroukhim, Rameen -- Mermel, Craig H -- Porter, Dale -- Wei, Guo -- Raychaudhuri, Soumya -- Donovan, Jerry -- Barretina, Jordi -- Boehm, Jesse S -- Dobson, Jennifer -- Urashima, Mitsuyoshi -- Mc Henry, Kevin T -- Pinchback, Reid M -- Ligon, Azra H -- Cho, Yoon-Jae -- Haery, Leila -- Greulich, Heidi -- Reich, Michael -- Winckler, Wendy -- Lawrence, Michael S -- Weir, Barbara A -- Tanaka, Kumiko E -- Chiang, Derek Y -- Bass, Adam J -- Loo, Alice -- Hoffman, Carter -- Prensner, John -- Liefeld, Ted -- Gao, Qing -- Yecies, Derek -- Signoretti, Sabina -- Maher, Elizabeth -- Kaye, Frederic J -- Sasaki, Hidefumi -- Tepper, Joel E -- Fletcher, Jonathan A -- Tabernero, Josep -- Baselga, Jose -- Tsao, Ming-Sound -- Demichelis, Francesca -- Rubin, Mark A -- Janne, Pasi A -- Daly, Mark J -- Nucera, Carmelo -- Levine, Ross L -- Ebert, Benjamin L -- Gabriel, Stacey -- Rustgi, Anil K -- Antonescu, Cristina R -- Ladanyi, Marc -- Letai, Anthony -- Garraway, Levi A -- Loda, Massimo -- Beer, David G -- True, Lawrence D -- Okamoto, Aikou -- Pomeroy, Scott L -- Singer, Samuel -- Golub, Todd R -- Lander, Eric S -- Getz, Gad -- Sellers, William R -- Meyerson, Matthew -- K08 AR055688/AR/NIAMS NIH HHS/ -- K08 AR055688-03/AR/NIAMS NIH HHS/ -- K08 AR055688-04/AR/NIAMS NIH HHS/ -- K08 CA122833/CA/NCI NIH HHS/ -- K08 CA122833-01A1/CA/NCI NIH HHS/ -- K08 CA122833-02/CA/NCI NIH HHS/ -- K08 CA122833-03/CA/NCI NIH HHS/ -- K08 CA134931/CA/NCI NIH HHS/ -- K08CA122833/CA/NCI NIH HHS/ -- P01CA 098101/CA/NCI NIH HHS/ -- P01CA085859/CA/NCI NIH HHS/ -- P50CA90578/CA/NCI NIH HHS/ -- R01 CA109038/CA/NCI NIH HHS/ -- R01 GM074024/GM/NIGMS NIH HHS/ -- R01CA109038/CA/NCI NIH HHS/ -- R01CA109467/CA/NCI NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- U24 CA126546/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Feb 18;463(7283):899-905. doi: 10.1038/nature08822.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Program and Medical and Population Genetics Group, The Broad Institute of M.I.T. and Harvard, 7 Cambridge Center.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20164920" target="_blank"〉PubMed〈/a〉

    An unexpectedly low oscillator strength as the origin of the Fe XVII emission problem (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-12-14
    Description: Highly charged iron (Fe(16+), here referred to as Fe XVII) produces some of the brightest X-ray emission lines from hot astrophysical objects, including galaxy clusters and stellar coronae, and it dominates the emission of the Sun at wavelengths near 15 angstroms. The Fe XVII spectrum is, however, poorly fitted by even the best astrophysical models. A particular problem has been that the intensity of the strongest Fe XVII line is generally weaker than predicted. This has affected the interpretation of observations by the Chandra and XMM-Newton orbiting X-ray missions, fuelling a continuing controversy over whether this discrepancy is caused by incomplete modelling of the plasma environment in these objects or by shortcomings in the treatment of the underlying atomic physics. Here we report the results of an experiment in which a target of iron ions was induced to fluoresce by subjecting it to femtosecond X-ray pulses from a free-electron laser; our aim was to isolate a key aspect of the quantum mechanical description of the line emission. Surprisingly, we find a relative oscillator strength that is unexpectedly low, differing by 3.6sigma from the best quantum mechanical calculations. Our measurements suggest that the poor agreement is rooted in the quality of the underlying atomic wavefunctions rather than in insufficient modelling of collisional processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bernitt, S -- Brown, G V -- Rudolph, J K -- Steinbrugge, R -- Graf, A -- Leutenegger, M -- Epp, S W -- Eberle, S -- Kubicek, K -- Mackel, V -- Simon, M C -- Trabert, E -- Magee, E W -- Beilmann, C -- Hell, N -- Schippers, S -- Muller, A -- Kahn, S M -- Surzhykov, A -- Harman, Z -- Keitel, C H -- Clementson, J -- Porter, F S -- Schlotter, W -- Turner, J J -- Ullrich, J -- Beiersdorfer, P -- Lopez-Urrutia, J R Crespo -- England -- Nature. 2012 Dec 13;492(7428):225-8. doi: 10.1038/nature11627.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Kernphysik, 69117 Heidelberg, Germany. sven.bernitt@mpi-hd.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23235875" target="_blank"〉PubMed〈/a〉

    De novo mutations in histone-modifying genes in congenital heart disease (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-05-15
    Description: Congenital heart disease (CHD) is the most frequent birth defect, affecting 0.8% of live births. Many cases occur sporadically and impair reproductive fitness, suggesting a role for de novo mutations. Here we compare the incidence of de novo mutations in 362 severe CHD cases and 264 controls by analysing exome sequencing of parent-offspring trios. CHD cases show a significant excess of protein-altering de novo mutations in genes expressed in the developing heart, with an odds ratio of 7.5 for damaging (premature termination, frameshift, splice site) mutations. Similar odds ratios are seen across the main classes of severe CHD. We find a marked excess of de novo mutations in genes involved in the production, removal or reading of histone 3 lysine 4 (H3K4) methylation, or ubiquitination of H2BK120, which is required for H3K4 methylation. There are also two de novo mutations in SMAD2, which regulates H3K27 methylation in the embryonic left-right organizer. The combination of both activating (H3K4 methylation) and inactivating (H3K27 methylation) chromatin marks characterizes 'poised' promoters and enhancers, which regulate expression of key developmental genes. These findings implicate de novo point mutations in several hundreds of genes that collectively contribute to approximately 10% of severe CHD.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3706629/" 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/PMC3706629/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zaidi, Samir -- Choi, Murim -- Wakimoto, Hiroko -- Ma, Lijiang -- Jiang, Jianming -- Overton, John D -- Romano-Adesman, Angela -- Bjornson, Robert D -- Breitbart, Roger E -- Brown, Kerry K -- Carriero, Nicholas J -- Cheung, Yee Him -- Deanfield, John -- DePalma, Steve -- Fakhro, Khalid A -- Glessner, Joseph -- Hakonarson, Hakon -- Italia, Michael J -- Kaltman, Jonathan R -- Kaski, Juan -- Kim, Richard -- Kline, Jennie K -- Lee, Teresa -- Leipzig, Jeremy -- Lopez, Alexander -- Mane, Shrikant M -- Mitchell, Laura E -- Newburger, Jane W -- Parfenov, Michael -- Pe'er, Itsik -- Porter, George -- Roberts, Amy E -- Sachidanandam, Ravi -- Sanders, Stephan J -- Seiden, Howard S -- State, Mathew W -- Subramanian, Sailakshmi -- Tikhonova, Irina R -- Wang, Wei -- Warburton, Dorothy -- White, Peter S -- Williams, Ismee A -- Zhao, Hongyu -- Seidman, Jonathan G -- Brueckner, Martina -- Chung, Wendy K -- Gelb, Bruce D -- Goldmuntz, Elizabeth -- Seidman, Christine E -- Lifton, Richard P -- 5U54HG006504/HG/NHGRI NIH HHS/ -- F30 HL123238/HL/NHLBI NIH HHS/ -- P30 HD018655/HD/NICHD NIH HHS/ -- T32 GM007205/GM/NIGMS NIH HHS/ -- U01 HG006546/HG/NHGRI NIH HHS/ -- U01 HL098123/HL/NHLBI NIH HHS/ -- U01 HL098147/HL/NHLBI NIH HHS/ -- U01 HL098153/HL/NHLBI NIH HHS/ -- U01 HL098162/HL/NHLBI NIH HHS/ -- U01 HL098163/HL/NHLBI NIH HHS/ -- U01-HL098123/HL/NHLBI NIH HHS/ -- U01-HL098147/HL/NHLBI NIH HHS/ -- U01-HL098153/HL/NHLBI NIH HHS/ -- U01-HL098162/HL/NHLBI NIH HHS/ -- U01-HL098163/HL/NHLBI NIH HHS/ -- U01-HL098188/HL/NHLBI NIH HHS/ -- U54 HG006504/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 Jun 13;498(7453):220-3. doi: 10.1038/nature12141.
