Description: Medulloblastoma is a highly malignant paediatric brain tumour currently treated with a combination of surgery, radiation and chemotherapy, posing a considerable burden of toxicity to the developing child. Genomics has illuminated the extensive intertumoral heterogeneity of medulloblastoma, identifying four distinct molecular subgroups. Group 3 and group 4 subgroup medulloblastomas account for most paediatric cases; yet, oncogenic drivers for these subtypes remain largely unidentified. Here we describe a series of prevalent, highly disparate genomic structural variants, restricted to groups 3 and 4, resulting in specific and mutually exclusive activation of the growth factor independent 1 family proto-oncogenes, GFI1 and GFI1B. Somatic structural variants juxtapose GFI1 or GFI1B coding sequences proximal to active enhancer elements, including super-enhancers, instigating oncogenic activity. Our results, supported by evidence from mouse models, identify GFI1 and GFI1B as prominent medulloblastoma oncogenes and implicate 'enhancer hijacking' as an efficient mechanism driving oncogene activation in a childhood cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4201514/" 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/PMC4201514/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Northcott, Paul A -- Lee, Catherine -- Zichner, Thomas -- Stutz, Adrian M -- Erkek, Serap -- Kawauchi, Daisuke -- Shih, David J H -- Hovestadt, Volker -- Zapatka, Marc -- Sturm, Dominik -- Jones, David T W -- Kool, Marcel -- Remke, Marc -- Cavalli, Florence M G -- Zuyderduyn, Scott -- Bader, Gary D -- VandenBerg, Scott -- Esparza, Lourdes Adriana -- Ryzhova, Marina -- Wang, Wei -- Wittmann, Andrea -- Stark, Sebastian -- Sieber, Laura -- Seker-Cin, Huriye -- Linke, Linda -- Kratochwil, Fabian -- Jager, Natalie -- Buchhalter, Ivo -- Imbusch, Charles D -- Zipprich, Gideon -- Raeder, Benjamin -- Schmidt, Sabine -- Diessl, Nicolle -- Wolf, Stephan -- Wiemann, Stefan -- Brors, Benedikt -- Lawerenz, Chris -- Eils, Jurgen -- Warnatz, Hans-Jorg -- Risch, Thomas -- Yaspo, Marie-Laure -- Weber, Ursula D -- Bartholomae, Cynthia C -- von Kalle, Christof -- Turanyi, Eszter -- Hauser, Peter -- Sanden, Emma -- Darabi, Anna -- Siesjo, Peter -- Sterba, Jaroslav -- Zitterbart, Karel -- Sumerauer, David -- van Sluis, Peter -- Versteeg, Rogier -- Volckmann, Richard -- Koster, Jan -- Schuhmann, Martin U -- Ebinger, Martin -- Grimes, H Leighton -- Robinson, Giles W -- Gajjar, Amar -- Mynarek, Martin -- von Hoff, Katja -- Rutkowski, Stefan -- Pietsch, Torsten -- Scheurlen, Wolfram -- Felsberg, Jorg -- Reifenberger, Guido -- Kulozik, Andreas E -- von Deimling, Andreas -- Witt, Olaf -- Eils, Roland -- Gilbertson, Richard J -- Korshunov, Andrey -- Taylor, Michael D -- Lichter, Peter -- Korbel, Jan O -- Wechsler-Reya, Robert J -- Pfister, Stefan M -- 5P30CA030199/CA/NCI NIH HHS/ -- P01 CA096832/CA/NCI NIH HHS/ -- P30 CA030199/CA/NCI NIH HHS/ -- P41GM103504/GM/NIGMS NIH HHS/ -- R01 CA159859/CA/NCI NIH HHS/ -- England -- Nature. 2014 Jul 24;511(7510):428-34. doi: 10.1038/nature13379.

Description: Activity-dependent modulation of synaptic efficacy in the brain contributes to neural circuit development and experience-dependent plasticity. Although glia are affected by activity and ensheathe synapses, their influence on synaptic strength has largely been ignored. Here, we show that a protein produced by glia, tumor necrosis factor alpha (TNFalpha), enhances synaptic efficacy by increasing surface expression of AMPA receptors. Preventing the actions of endogenous TNFalpha has the opposite effects. Thus, the continual presence of TNFalpha is required for preservation of synaptic strength at excitatory synapses. Through its effects on AMPA receptor trafficking, TNFalpha may play roles in synaptic plasticity and modulating responses to neural injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beattie, Eric C -- Stellwagen, David -- Morishita, Wade -- Bresnahan, Jacqueline C -- Ha, Byeong Keun -- Von Zastrow, Mark -- Beattie, Michael S -- Malenka, Robert C -- DA00439/DA/NIDA NIH HHS/ -- MH063394/MH/NIMH NIH HHS/ -- NS 31193/NS/NINDS NIH HHS/ -- NS38079/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2002 Mar 22;295(5563):2282-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nancy Pritzker Laboratory, Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Palo Alto, CA 94304, USA. beattie.2@osu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11910117" target="_blank"〉PubMed〈/a〉

Description: Pseudomonas aeruginosa causes severe infections, particularly of the lung, that are life threatening. Here, we show that P. aeruginosa infection induces apoptosis of lung epithelial cells by activation of the endogenous CD95/CD95 ligand system. Deficiency of CD95 or CD95 ligand on epithelial cells prevented apoptosis of lung epithelial cells in vivo as well as in vitro. The importance of CD95/CD95 ligand-mediated lung epithelial cell apoptosis was demonstrated by the rapid development of sepsis in CD95- or CD95 ligand-deficient mice, but not in normal mice, after P. aeruginosa infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grassme, H -- Kirschnek, S -- Riethmueller, J -- Riehle, A -- von Kurthy, G -- Lang, F -- Weller, M -- Gulbins, E -- New York, N.Y. -- Science. 2000 Oct 20;290(5491):527-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, University of Tuebingen, Gmelinstrasse 5, 72076 Tuebingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11039936" target="_blank"〉PubMed〈/a〉

Description: One of the most dominant influences in the patterning of multicellular embryos is exerted by the Hedgehog (Hh) family of secreted signaling proteins. Here, we identify a segment polarity gene in Drosophila melanogaster, skinny hedgehog (ski), and show that its product is required in Hh-expressing cells for production of appropriate signaling activity in embryos and in the imaginal precursors of adult tissues. The ski gene encodes an apparent acyltransferase, and we provide genetic and biochemical evidence that Hh proteins from ski mutant cells retain carboxyl-terminal cholesterol modification but lack amino-terminal palmitate modification. Our results suggest that ski encodes an enzyme that acts within the secretory pathway to catalyze amino-terminal palmitoylation of Hh, and further demonstrate that this lipid modification is required for the embryonic and larval patterning activities of the Hh signal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chamoun, Z -- Mann, R K -- Nellen, D -- von Kessler, D P -- Bellotto, M -- Beachy, P A -- Basler, K -- New York, N.Y. -- Science. 2001 Sep 14;293(5537):2080-4.

Description: Isotopic analysis of human blood and liver and muscle tissue indicates that each individual bears a long-term iron (Fe) isotope signature in the blood. Blood and tissue differ slightly in isotopic composition and are depleted by up to 2.6 per mil in 56Fe relative to 54Fe when compared to dietary Fe. The 56Fe/54Fe isotope ratio in the blood of males is, on average, lower by 0.3 per mil than that of females. These results suggest that Fe isotope effects in the blood reflect differences in intestinal Fe absorption between individuals and genotypes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walczyk, Thomas -- von Blanckenburg, Friedhelm -- New York, N.Y. -- Science. 2002 Mar 15;295(5562):2065-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Human Nutrition, Institute of Food Sciences, Swiss Federal Institute of Technology (ETH) Zurich, Seestrasse 72, CH-8803 Ruschlikon, Switzerland. thomas.walczyk@ilw.agrl.ethz.ch〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11896276" target="_blank"〉PubMed〈/a〉

Description: In vitro PA28 binds and activates proteasomes. It is shown here that mice with a disrupted PA28b gene lack PA28a and PA28b polypeptides, demonstrating that PA28 functions as a hetero-oligomer in vivo. Processing of antigenic epitopes derived from exogenous or endogenous antigens is altered in PA28-/- mice. Cytotoxic T lymphocyte responses are impaired, and assembly of immunoproteasomes is greatly inhibited in mice lacking PA28. These results show that PA28 is necessary for immunoproteasome assembly and is required for efficient antigen processing, thus demonstrating the importance of PA28-mediated proteasome function in immune responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Preckel, T -- Fung-Leung, W P -- Cai, Z -- Vitiello, A -- Salter-Cid, L -- Winqvist, O -- Wolfe, T G -- Von Herrath, M -- Angulo, A -- Ghazal, P -- Lee, J D -- Fourie, A M -- Wu, Y -- Pang, J -- Ngo, K -- Peterson, P A -- Fruh, K -- Yang, Y -- New York, N.Y. -- Science. 1999 Dec 10;286(5447):2162-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The R.

Description: Circadian rhythms of mammals are entrained by light to follow the daily solar cycle (photoentrainment). To determine whether retinal rods and cones are required for this response, the effects of light on the regulation of circadian wheel-running behavior were examined in mice lacking these photoreceptors. Mice without cones (cl) or without both rods and cones (rdta/cl) showed unattenuated phase-shifting responses to light. Removal of the eyes abolishes this behavior. Thus, neither rods nor cones are required for photoentrainment, and the murine eye contains additional photoreceptors that regulate the circadian clock.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Freedman, M S -- Lucas, R J -- Soni, B -- von Schantz, M -- Munoz, M -- David-Gray, Z -- Foster, R -- New York, N.Y. -- Science. 1999 Apr 16;284(5413):502-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Alexander Fleming Building, Imperial College of Science, Technology and Medicine, London, SW7 2AZ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10205061" target="_blank"〉PubMed〈/a〉
