    Description: Glioblastoma multiforme (GBM) is the most common and lethal type of brain cancer. To identify the genetic alterations in GBMs, we sequenced 20,661 protein coding genes, determined the presence of amplifications and deletions using high-density oligonucleotide arrays, and performed gene expression analyses using next-generation sequencing technologies in 22 human tumor samples. This comprehensive analysis led to the discovery of a variety of genes that were not known to be altered in GBMs. Most notably, we found recurrent mutations in the active site of isocitrate dehydrogenase 1 (IDH1) in 12% of GBM patients. Mutations in IDH1 occurred in a large fraction of young patients and in most patients with secondary GBMs and were associated with an increase in overall survival. These studies demonstrate the value of unbiased genomic analyses in the characterization of human brain cancer and identify a potentially useful genetic alteration for the classification and targeted therapy of GBMs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820389/" 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/PMC2820389/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parsons, D Williams -- Jones, Sian -- Zhang, Xiaosong -- Lin, Jimmy Cheng-Ho -- Leary, Rebecca J -- Angenendt, Philipp -- Mankoo, Parminder -- Carter, Hannah -- Siu, I-Mei -- Gallia, Gary L -- Olivi, Alessandro -- McLendon, Roger -- Rasheed, B Ahmed -- Keir, Stephen -- Nikolskaya, Tatiana -- Nikolsky, Yuri -- Busam, Dana A -- Tekleab, Hanna -- Diaz, Luis A Jr -- Hartigan, James -- Smith, Doug R -- Strausberg, Robert L -- Marie, Suely Kazue Nagahashi -- Shinjo, Sueli Mieko Oba -- Yan, Hai -- Riggins, Gregory J -- Bigner, Darell D -- Karchin, Rachel -- Papadopoulos, Nick -- Parmigiani, Giovanni -- Vogelstein, Bert -- Velculescu, Victor E -- Kinzler, Kenneth W -- 5P50-NS-20023/NS/NINDS NIH HHS/ -- CA09547/CA/NCI NIH HHS/ -- CA108786/CA/NCI NIH HHS/ -- CA11898/CA/NCI NIH HHS/ -- CA121113/CA/NCI NIH HHS/ -- CA43460/CA/NCI NIH HHS/ -- CA57345/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- NS052507/NS/NINDS NIH HHS/ -- P50 CA062924/CA/NCI NIH HHS/ -- P50 CA062924-160017/CA/NCI NIH HHS/ -- R01 CA121113/CA/NCI NIH HHS/ -- R01 CA121113-04/CA/NCI NIH HHS/ -- R01 CA140316/CA/NCI NIH HHS/ -- R37 CA043460/CA/NCI NIH HHS/ -- R37 CA043460-27/CA/NCI NIH HHS/ -- R37 CA057345/CA/NCI NIH HHS/ -- R37 CA057345-13/CA/NCI NIH HHS/ -- R37 CA057345-17/CA/NCI NIH HHS/ -- R37 CA057345-18/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Sep 26;321(5897):1807-12. doi: 10.1126/science.1164382.

    Description: After disappointing results from all efficacy trials conducted to date, the field of microbicides research now faces substantial challenges. Poor coordination among interested parties and the choice of nonvalidated scientific targets for phase III studies have hampered progress and created mistrust about the use of microbicides as a method to prevent HIV-1 sexual transmission. Although new promising strategies are available, there will need to be serious reappraisals of how decisions are made to advance the next generations of candidates into clinical trials, and the use of appropriate animal models in this process will be critical.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2835691/" 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/PMC2835691/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grant, Robert M -- Hamer, Dean -- Hope, Thomas -- Johnston, Rowena -- Lange, Joep -- Lederman, Michael M -- Lieberman, Judy -- Miller, Christopher J -- Moore, John P -- Mosier, Donald E -- Richman, Douglas D -- Schooley, Robert T -- Springer, Marty S -- Veazey, Ronald S -- Wainberg, Mark A -- U19 AI076981/AI/NIAID NIH HHS/ -- U19 AI076981-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2008 Jul 25;321(5888):532-4. doi: 10.1126/science.1160355.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉J.

    Description: Almost two decades after CFTR was identified as the gene responsible for cystic fibrosis (CF), we still lack answers to many questions about the pathogenesis of the disease, and it remains incurable. Mice with a disrupted CFTR gene have greatly facilitated CF studies, but the mutant mice do not develop the characteristic manifestations of human CF, including abnormalities of the pancreas, lung, intestine, liver, and other organs. Because pigs share many anatomical and physiological features with humans, we generated pigs with a targeted disruption of both CFTR alleles. Newborn pigs lacking CFTR exhibited defective chloride transport and developed meconium ileus, exocrine pancreatic destruction, and focal biliary cirrhosis, replicating abnormalities seen in newborn humans with CF. The pig model may provide opportunities to address persistent questions about CF pathogenesis and accelerate discovery of strategies for prevention and treatment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2570747/" 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/PMC2570747/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rogers, Christopher S -- Stoltz, David A -- Meyerholz, David K -- Ostedgaard, Lynda S -- Rokhlina, Tatiana -- Taft, Peter J -- Rogan, Mark P -- Pezzulo, Alejandro A -- Karp, Philip H -- Itani, Omar A -- Kabel, Amanda C -- Wohlford-Lenane, Christine L -- Davis, Greg J -- Hanfland, Robert A -- Smith, Tony L -- Samuel, Melissa -- Wax, David -- Murphy, Clifton N -- Rieke, August -- Whitworth, Kristin -- Uc, Aliye -- Starner, Timothy D -- Brogden, Kim A -- Shilyansky, Joel -- McCray, Paul B Jr -- Zabner, Joseph -- Prather, Randall S -- Welsh, Michael J -- AI076671/AI/NIAID NIH HHS/ -- DK54759/DK/NIDDK NIH HHS/ -- HL07638/HL/NHLBI NIH HHS/ -- HL51670/HL/NHLBI NIH HHS/ -- K08 AI076671/AI/NIAID NIH HHS/ -- K08 AI076671-01/AI/NIAID NIH HHS/ -- P01 HL051670/HL/NHLBI NIH HHS/ -- P01 HL051670-15/HL/NHLBI NIH HHS/ -- P30 DK054759/DK/NIDDK NIH HHS/ -- P30 DK054759-10/DK/NIDDK NIH HHS/ -- P30 DK054759-109004/DK/NIDDK NIH HHS/ -- R01 DK051315/DK/NIDDK NIH HHS/ -- T32 HL007638/HL/NHLBI NIH HHS/ -- T32 HL007638-23/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Sep 26;321(5897):1837-41. doi: 10.1126/science.1163600.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, Roy J. and Lucille A.

    Description: Alcohol dependence is a major public health challenge in need of new treatments. As alcoholism evolves, stress systems in the brain play an increasing role in motivating continued alcohol use and relapse. We investigated the role of the neurokinin 1 receptor (NK1R), a mediator of behavioral stress responses, in alcohol dependence and treatment. In preclinical studies, mice genetically deficient in NK1R showed a marked decrease in voluntary alcohol consumption and had an increased sensitivity to the sedative effects of alcohol. In a randomized controlled experimental study, we treated recently detoxified alcoholic inpatients with an NK1R antagonist (LY686017; n = 25) or placebo (n = 25). LY686017 suppressed spontaneous alcohol cravings, improved overall well-being, blunted cravings induced by a challenge procedure, and attenuated concomitant cortisol responses. Brain functional magnetic resonance imaging responses to affective stimuli likewise suggested beneficial LY686017 effects. Thus, as assessed by these surrogate markers of efficacy, NK1R antagonism warrants further investigation as a treatment in alcoholism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉George, David T -- Gilman, Jodi -- Hersh, Jacqueline -- Thorsell, Annika -- Herion, David -- Geyer, Christopher -- Peng, Xiaomei -- Kielbasa, William -- Rawlings, Robert -- Brandt, John E -- Gehlert, Donald R -- Tauscher, Johannes T -- Hunt, Stephen P -- Hommer, Daniel -- Heilig, Markus -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Mar 14;319(5869):1536-9. doi: 10.1126/science.1153813.

    Description: The control of innate immune responses through activation of the nuclear transcription factor NF-kappaB is essential for the elimination of invading microbial pathogens. We showed that the bacterial N-(3-oxo-dodecanoyl) homoserine lactone (C12) selectively impairs the regulation of NF-kappaB functions in activated mammalian cells. The consequence is specific repression of stimulus-mediated induction of NF-kappaB-responsive genes encoding inflammatory cytokines and other immune regulators. These findings uncover a strategy by which C12-producing opportunistic pathogens, such as Pseudomonas aeruginosa, attenuate the innate immune system to establish and maintain local persistent infection in humans, for example, in cystic fibrosis patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kravchenko, Vladimir V -- Kaufmann, Gunnar F -- Mathison, John C -- Scott, David A -- Katz, Alexander Z -- Grauer, David C -- Lehmann, Mandy -- Meijler, Michael M -- Janda, Kim D -- Ulevitch, Richard J -- New York, N.Y. -- Science. 2008 Jul 11;321(5886):259-63. doi: 10.1126/science.1156499.

    Description: The repeated discovery of adult dinosaurs in close association with egg clutches leads to speculation over the type and extent of care exhibited by these extinct animals for their eggs and young. To assess parental care in Cretaceous troodontid and oviraptorid dinosaurs, we examined clutch volume and the bone histology of brooding adults. In comparison to four archosaur care regressions, the relatively large clutch volumes of Troodon, Oviraptor, and Citipati scale most closely with a bird-paternal care model. Clutch-associated adults lack the maternal and reproductively associated histologic features common to extant archosaurs. Large clutch volumes and a suite of reproductive features shared only with birds favor paternal care, possibly within a polygamous mating system. Paternal care in both troodontids and oviraptorids indicates that this care system evolved before the emergence of birds and represents birds' ancestral condition. In extant birds and over most adult sizes, paternal and biparental care correspond to the largest and smallest relative clutch volumes, respectively.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Varricchio, David J -- Moore, Jason R -- Erickson, Gregory M -- Norell, Mark A -- Jackson, Frankie D -- Borkowski, John J -- New York, N.Y. -- Science. 2008 Dec 19;322(5909):1826-8. doi: 10.1126/science.1163245.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, Montana State University, Bozeman, MT 59717, USA. djv@montana.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19095938" target="_blank"〉PubMed〈/a〉

    Description: We have developed a biomechanical energy harvester that generates electricity during human walking with little extra effort. Unlike conventional human-powered generators that use positive muscle work, our technology assists muscles in performing negative work, analogous to regenerative braking in hybrid cars, where energy normally dissipated during braking drives a generator instead. The energy harvester mounts at the knee and selectively engages power generation at the end of the swing phase, thus assisting deceleration of the joint. Test subjects walking with one device on each leg produced an average of 5 watts of electricity, which is about 10 times that of shoe-mounted devices. The cost of harvesting-the additional metabolic power required to produce 1 watt of electricity-is less than one-eighth of that for conventional human power generation. Producing substantial electricity with little extra effort makes this method well-suited for charging powered prosthetic limbs and other portable medical devices.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Donelan, J M -- Li, Q -- Naing, V -- Hoffer, J A -- Weber, D J -- Kuo, A D -- New York, N.Y. -- Science. 2008 Feb 8;319(5864):807-10. doi: 10.1126/science.1149860.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Kinesiology, Simon Fraser University (SFU), Burnaby, BC V5A 1S6, Canada. mdonelan@sfu.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18258914" target="_blank"〉PubMed〈/a〉

    Description: Development of axonal tracts requires interactions between growth cones and the environment. Tracts such as the anterior commissure and internal capsule are defective in mice with null mutation of Celsr3. We generated a conditional Celsr3 allele, allowing regional inactivation. Inactivation in telencephalon, ventral forebrain, or cortex demonstrated essential roles for Celsr3 in neurons that project axons to the anterior commissure and subcerebral targets, as well as in cells that guide axons through the internal capsule. When Celsr3 was inactivated in cortex, subcerebral projections failed to grow, yet corticothalamic axons developed normally, indicating that besides guidepost cells, additional Celsr3-independent cues can assist their progression. These observations provide in vivo evidence that Celsr3-mediated interactions between axons and guidepost cells govern axonal tract formation in mammals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2746700/" 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/PMC2746700/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Libing -- Bar, Isabelle -- Achouri, Younes -- Campbell, Kenneth -- De Backer, Olivier -- Hebert, Jean M -- Jones, Kevin -- Kessaris, Nicoletta -- de Rouvroit, Catherine Lambert -- O'Leary, Dennis -- Richardson, William D -- Goffinet, Andre M -- Tissir, Fadel -- G0501173/Medical Research Council/United Kingdom -- G0800575/Medical Research Council/United Kingdom -- G9708005/Medical Research Council/United Kingdom -- R01 MH086147/MH/NIMH NIH HHS/ -- R01 MH086147-05/MH/NIMH NIH HHS/ -- R37 NS031558/NS/NINDS NIH HHS/ -- R37 NS031558-15/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2008 May 16;320(5878):946-9. doi: 10.1126/science.1155244.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Developmental Neurobiology, Universite Catholique de Louvain, 1200 Bruxelles, Belgique.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18487195" target="_blank"〉PubMed〈/a〉
