    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.

    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〉

    Description: The US National Institute of Neurological Disorders and Stroke convened major stakeholders in June 2012 to discuss how to improve the methodological reporting of animal studies in grant applications and publications. The main workshop recommendation is that at a minimum studies should report on sample-size estimation, whether and how animals were randomized, whether investigators were blind to the treatment, and the handling of data. We recognize that achieving a meaningful improvement in the quality of reporting will require a concerted effort by investigators, reviewers, funding agencies and journal editors. Requiring better reporting of animal studies will raise awareness of the importance of rigorous study design to accelerate scientific progress.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3511845/" 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/PMC3511845/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Landis, Story C -- Amara, Susan G -- Asadullah, Khusru -- Austin, Chris P -- Blumenstein, Robi -- Bradley, Eileen W -- Crystal, Ronald G -- Darnell, Robert B -- Ferrante, Robert J -- Fillit, Howard -- Finkelstein, Robert -- Fisher, Marc -- Gendelman, Howard E -- Golub, Robert M -- Goudreau, John L -- Gross, Robert A -- Gubitz, Amelie K -- Hesterlee, Sharon E -- Howells, David W -- Huguenard, John -- Kelner, Katrina -- Koroshetz, Walter -- Krainc, Dimitri -- Lazic, Stanley E -- Levine, Michael S -- Macleod, Malcolm R -- McCall, John M -- Moxley, Richard T 3rd -- Narasimhan, Kalyani -- Noble, Linda J -- Perrin, Steve -- Porter, John D -- Steward, Oswald -- Unger, Ellis -- Utz, Ursula -- Silberberg, Shai D -- P01 NS012151/NS/NINDS NIH HHS/ -- P30 MH062261/MH/NIMH NIH HHS/ -- R01 NS006477/NS/NINDS NIH HHS/ -- R01 NS034774/NS/NINDS NIH HHS/ -- R01 NS041574/NS/NINDS NIH HHS/ -- T32 MH020016/MH/NIMH NIH HHS/ -- T32 NS007280/NS/NINDS NIH HHS/ -- UL1 RR024160/RR/NCRR NIH HHS/ -- Z99 NS999999/Intramural NIH HHS/ -- England -- Nature. 2012 Oct 11;490(7419):187-91. doi: 10.1038/nature11556.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Neurological Disorders and Stroke, NIH, Bethesda, Maryland 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23060188" target="_blank"〉PubMed〈/a〉

    Description: The systematic translation of cancer genomic data into knowledge of tumour biology and therapeutic possibilities remains challenging. Such efforts should be greatly aided by robust preclinical model systems that reflect the genomic diversity of human cancers and for which detailed genetic and pharmacological annotation is available. Here we describe the Cancer Cell Line Encyclopedia (CCLE): a compilation of gene expression, chromosomal copy number and massively parallel sequencing data from 947 human cancer cell lines. When coupled with pharmacological profiles for 24 anticancer drugs across 479 of the cell lines, this collection allowed identification of genetic, lineage, and gene-expression-based predictors of drug sensitivity. In addition to known predictors, we found that plasma cell lineage correlated with sensitivity to IGF1 receptor inhibitors; AHR expression was associated with MEK inhibitor efficacy in NRAS-mutant lines; and SLFN11 expression predicted sensitivity to topoisomerase inhibitors. Together, our results indicate that large, annotated cell-line collections may help to enable preclinical stratification schemata for anticancer agents. The generation of genetic predictions of drug response in the preclinical setting and their incorporation into cancer clinical trial design could speed the emergence of 'personalized' therapeutic regimens.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3320027/" 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/PMC3320027/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barretina, Jordi -- Caponigro, Giordano -- Stransky, Nicolas -- Venkatesan, Kavitha -- Margolin, Adam A -- Kim, Sungjoon -- Wilson, Christopher J -- Lehar, Joseph -- Kryukov, Gregory V -- Sonkin, Dmitriy -- Reddy, Anupama -- Liu, Manway -- Murray, Lauren -- Berger, Michael F -- Monahan, John E -- Morais, Paula -- Meltzer, Jodi -- Korejwa, Adam -- Jane-Valbuena, Judit -- Mapa, Felipa A -- Thibault, Joseph -- Bric-Furlong, Eva -- Raman, Pichai -- Shipway, Aaron -- Engels, Ingo H -- Cheng, Jill -- Yu, Guoying K -- Yu, Jianjun -- Aspesi, Peter Jr -- de Silva, Melanie -- Jagtap, Kalpana -- Jones, Michael D -- Wang, Li -- Hatton, Charles -- Palescandolo, Emanuele -- Gupta, Supriya -- Mahan, Scott -- Sougnez, Carrie -- Onofrio, Robert C -- Liefeld, Ted -- MacConaill, Laura -- Winckler, Wendy -- Reich, Michael -- Li, Nanxin -- Mesirov, Jill P -- Gabriel, Stacey B -- Getz, Gad -- Ardlie, Kristin -- Chan, Vivien -- Myer, Vic E -- Weber, Barbara L -- Porter, Jeff -- Warmuth, Markus -- Finan, Peter -- Harris, Jennifer L -- Meyerson, Matthew -- Golub, Todd R -- Morrissey, Michael P -- Sellers, William R -- Schlegel, Robert -- Garraway, Levi A -- DP2 OD002750/OD/NIH HHS/ -- DP2 OD002750-01/OD/NIH HHS/ -- R33 CA126674/CA/NCI NIH HHS/ -- R33 CA126674-04/CA/NCI NIH HHS/ -- R33 CA155554/CA/NCI NIH HHS/ -- R33 CA155554-02/CA/NCI NIH HHS/ -- England -- Nature. 2012 Mar 28;483(7391):603-7. doi: 10.1038/nature11003.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Broad Institute of Harvard and MIT, Cambridge, Massachusetts 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22460905" target="_blank"〉PubMed〈/a〉

    Description: Hypertension affects one billion people and is a principal reversible risk factor for cardiovascular disease. Pseudohypoaldosteronism type II (PHAII), a rare Mendelian syndrome featuring hypertension, hyperkalaemia and metabolic acidosis, has revealed previously unrecognized physiology orchestrating the balance between renal salt reabsorption and K(+) and H(+) excretion. Here we used exome sequencing to identify mutations in kelch-like 3 (KLHL3) or cullin 3 (CUL3) in PHAII patients from 41 unrelated families. KLHL3 mutations are either recessive or dominant, whereas CUL3 mutations are dominant and predominantly de novo. CUL3 and BTB-domain-containing kelch proteins such as KLHL3 are components of cullin-RING E3 ligase complexes that ubiquitinate substrates bound to kelch propeller domains. Dominant KLHL3 mutations are clustered in short segments within the kelch propeller and BTB domains implicated in substrate and cullin binding, respectively. Diverse CUL3 mutations all result in skipping of exon 9, producing an in-frame deletion. Because dominant KLHL3 and CUL3 mutations both phenocopy recessive loss-of-function KLHL3 mutations, they may abrogate ubiquitination of KLHL3 substrates. Disease features are reversed by thiazide diuretics, which inhibit the Na-Cl cotransporter in the distal nephron of the kidney; KLHL3 and CUL3 are expressed in this location, suggesting a mechanistic link between KLHL3 and CUL3 mutations, increased Na-Cl reabsorption, and disease pathogenesis. These findings demonstrate the utility of exome sequencing in disease gene identification despite the combined complexities of locus heterogeneity, mixed models of transmission and frequent de novo mutation, and establish a fundamental role for KLHL3 and CUL3 in blood pressure, K(+) and pH homeostasis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3278668/" 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/PMC3278668/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boyden, Lynn M -- Choi, Murim -- Choate, Keith A -- Nelson-Williams, Carol J -- Farhi, Anita -- Toka, Hakan R -- Tikhonova, Irina R -- Bjornson, Robert -- Mane, Shrikant M -- Colussi, Giacomo -- Lebel, Marcel -- Gordon, Richard D -- Semmekrot, Ben A -- Poujol, Alain -- Valimaki, Matti J -- De Ferrari, Maria E -- Sanjad, Sami A -- Gutkin, Michael -- Karet, Fiona E -- Tucci, Joseph R -- Stockigt, Jim R -- Keppler-Noreuil, Kim M -- Porter, Craig C -- Anand, Sudhir K -- Whiteford, Margo L -- Davis, Ira D -- Dewar, Stephanie B -- Bettinelli, Alberto -- Fadrowski, Jeffrey J -- Belsha, Craig W -- Hunley, Tracy E -- Nelson, Raoul D -- Trachtman, Howard -- Cole, Trevor R P -- Pinsk, Maury -- Bockenhauer, Detlef -- Shenoy, Mohan -- Vaidyanathan, Priya -- Foreman, John W -- Rasoulpour, Majid -- Thameem, Farook -- Al-Shahrouri, Hania Z -- Radhakrishnan, Jai -- Gharavi, Ali G -- Goilav, Beatrice -- Lifton, Richard P -- KL2 RR024138/RR/NCRR NIH HHS/ -- KL2 RR024138-07/RR/NCRR NIH HHS/ -- P30 DK079310/DK/NIDDK NIH HHS/ -- P30 DK079310-04S1/DK/NIDDK NIH HHS/ -- P30-DK079310/DK/NIDDK NIH HHS/ -- UL1-RR024139/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Jan 22;482(7383):98-102. doi: 10.1038/nature10814.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics and Howard Hughes Medical Institute, Yale University School of Medicine, New Haven, Connecticut 06510, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22266938" target="_blank"〉PubMed〈/a〉

    Description: R-spondin proteins strongly potentiate Wnt signalling and function as stem-cell growth factors. Despite the biological and therapeutic significance, the molecular mechanism of R-spondin action remains unclear. Here we show that the cell-surface transmembrane E3 ubiquitin ligase zinc and ring finger 3 (ZNRF3) and its homologue ring finger 43 (RNF43) are negative feedback regulators of Wnt signalling. ZNRF3 is associated with the Wnt receptor complex, and inhibits Wnt signalling by promoting the turnover of frizzled and LRP6. Inhibition of ZNRF3 enhances Wnt/beta-catenin signalling and disrupts Wnt/planar cell polarity signalling in vivo. Notably, R-spondin mimics ZNRF3 inhibition by increasing the membrane level of Wnt receptors. Mechanistically, R-spondin interacts with the extracellular domain of ZNRF3 and induces the association between ZNRF3 and LGR4, which results in membrane clearance of ZNRF3. These data suggest that R-spondin enhances Wnt signalling by inhibiting ZNRF3. Our study provides new mechanistic insights into the regulation of Wnt receptor turnover, and reveals ZNRF3 as a tractable target for therapeutic exploration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hao, Huai-Xiang -- Xie, Yang -- Zhang, Yue -- Charlat, Olga -- Oster, Emma -- Avello, Monika -- Lei, Hong -- Mickanin, Craig -- Liu, Dong -- Ruffner, Heinz -- Mao, Xiaohong -- Ma, Qicheng -- Zamponi, Raffaella -- Bouwmeester, Tewis -- Finan, Peter M -- Kirschner, Marc W -- Porter, Jeffery A -- Serluca, Fabrizio C -- Cong, Feng -- England -- Nature. 2012 Apr 29;485(7397):195-200. doi: 10.1038/nature11019.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Novartis Institutes for Biomedical Research, 250 Massachusetts Avenue, Cambridge, Massachusetts 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22575959" target="_blank"〉PubMed〈/a〉

    Description: We report the observation of a large linear magnetoresistance in the ohmic regime in commonplace commercial n-type silicon wafer with a P dopant density of (1.4±0.1) ×1015 cm–3, and report measurements of it in the temperature range 30–200 K. It arises from the deformation of current paths, which causes a part of the Hall field to be detected at the voltage probes. In short, wide samples we found linear magnetoresistance as large as 4707% in an 8 tesla field at 35 K. Sample geometry effects like these are commonplace in commercial Hall sensors. However, we found that the effect persisted in long, thin samples where the macroscopic current flow should be uniform between the voltage probes: we observed a magnetoresistance of 445% under the same conditions as above. We interpret this result as arising due to spatial fluctuations in the donor density, in the spirit of the Herring model. Scientific Reports 2 doi: 10.1038/srep00565
