    The genomic landscapes of human breast and colorectal cancers (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-13
    Description: Human cancer is caused by the accumulation of mutations in oncogenes and tumor suppressor genes. To catalog the genetic changes that occur during tumorigenesis, we isolated DNA from 11 breast and 11 colorectal tumors and determined the sequences of the genes in the Reference Sequence database in these samples. Based on analysis of exons representing 20,857 transcripts from 18,191 genes, we conclude that the genomic landscapes of breast and colorectal cancers are composed of a handful of commonly mutated gene "mountains" and a much larger number of gene "hills" that are mutated at low frequency. We describe statistical and bioinformatic tools that may help identify mutations with a role in tumorigenesis. These results have implications for understanding the nature and heterogeneity of human cancers and for using personal genomics for tumor diagnosis and therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wood, Laura D -- Parsons, D Williams -- Jones, Sian -- Lin, Jimmy -- Sjoblom, Tobias -- Leary, Rebecca J -- Shen, Dong -- Boca, Simina M -- Barber, Thomas -- Ptak, Janine -- Silliman, Natalie -- Szabo, Steve -- Dezso, Zoltan -- Ustyanksky, Vadim -- Nikolskaya, Tatiana -- Nikolsky, Yuri -- Karchin, Rachel -- Wilson, Paul A -- Kaminker, Joshua S -- Zhang, Zemin -- Croshaw, Randal -- Willis, Joseph -- Dawson, Dawn -- Shipitsin, Michail -- Willson, James K V -- Sukumar, Saraswati -- Polyak, Kornelia -- Park, Ben Ho -- Pethiyagoda, Charit L -- Pant, P V Krishna -- Ballinger, Dennis G -- Sparks, Andrew B -- Hartigan, James -- Smith, Douglas R -- Suh, Erick -- Papadopoulos, Nickolas -- Buckhaults, Phillip -- Markowitz, Sanford D -- Parmigiani, Giovanni -- Kinzler, Kenneth W -- Velculescu, Victor E -- Vogelstein, Bert -- CA 43460/CA/NCI NIH HHS/ -- CA 57345/CA/NCI NIH HHS/ -- CA109274/CA/NCI NIH HHS/ -- CA112828/CA/NCI NIH HHS/ -- CA121113/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- GM070219/GM/NIGMS NIH HHS/ -- GM07309/GM/NIGMS NIH HHS/ -- P30-CA43703/CA/NCI NIH HHS/ -- RR017698/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 16;318(5853):1108-13.

    Common Kibra alleles are associated with human memory performance (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-10-21
    Description: Human memory is a polygenic trait. We performed a genome-wide screen to identify memory-related gene variants. A genomic locus encoding the brain protein KIBRA was significantly associated with memory performance in three independent, cognitively normal cohorts from Switzerland and the United States. Gene expression studies showed that KIBRA was expressed in memory-related brain structures. Functional magnetic resonance imaging detected KIBRA allele-dependent differences in hippocampal activations during memory retrieval. Evidence from these experiments suggests a role for KIBRA in human memory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Papassotiropoulos, Andreas -- Stephan, Dietrich A -- Huentelman, Matthew J -- Hoerndli, Frederic J -- Craig, David W -- Pearson, John V -- Huynh, Kim-Dung -- Brunner, Fabienne -- Corneveaux, Jason -- Osborne, David -- Wollmer, M Axel -- Aerni, Amanda -- Coluccia, Daniel -- Hanggi, Jurgen -- Mondadori, Christian R A -- Buchmann, Andreas -- Reiman, Eric M -- Caselli, Richard J -- Henke, Katharina -- de Quervain, Dominique J-F -- P30AG19610/AG/NIA NIH HHS/ -- R01MH057899/MH/NIMH NIH HHS/ -- U01-HL086528-01/HL/NHLBI NIH HHS/ -- U24NS051872/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2006 Oct 20;314(5798):475-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Psychiatry Research, University of Zurich, Zurich 8057, Switzerland. papas@bli.unizh.ch〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17053149" target="_blank"〉PubMed〈/a〉

    Losartan, an AT1 antagonist, prevents aortic aneurysm in a mouse model of Marfan syndrome (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-08
    Description: Aortic aneurysm and dissection are manifestations of Marfan syndrome (MFS), a disorder caused by mutations in the gene that encodes fibrillin-1. Selected manifestations of MFS reflect excessive signaling by the transforming growth factor-beta (TGF-beta) family of cytokines. We show that aortic aneurysm in a mouse model of MFS is associated with increased TGF-beta signaling and can be prevented by TGF-beta antagonists such as TGF-beta-neutralizing antibody or the angiotensin II type 1 receptor (AT1) blocker, losartan. AT1 antagonism also partially reversed noncardiovascular manifestations of MFS, including impaired alveolar septation. These data suggest that losartan, a drug already in clinical use for hypertension, merits investigation as a therapeutic strategy for patients with MFS and has the potential to prevent the major life-threatening manifestation of this disorder.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1482474/" 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/PMC1482474/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Habashi, Jennifer P -- Judge, Daniel P -- Holm, Tammy M -- Cohn, Ronald D -- Loeys, Bart L -- Cooper, Timothy K -- Myers, Loretha -- Klein, Erin C -- Liu, Guosheng -- Calvi, Carla -- Podowski, Megan -- Neptune, Enid R -- Halushka, Marc K -- Bedja, Djahida -- Gabrielson, Kathleen -- Rifkin, Daniel B -- Carta, Luca -- Ramirez, Francesco -- Huso, David L -- Dietz, Harry C -- K08 HL067056/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 7;312(5770):117-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Pediatrics, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16601194" target="_blank"〉PubMed〈/a〉

    Pulsatile stimulation determines timing and specificity of NF-kappaB-dependent transcription (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-04-11
    Description: The nuclear factor kappaB (NF-kappaB) transcription factor regulates cellular stress responses and the immune response to infection. NF-kappaB activation results in oscillations in nuclear NF-kappaB abundance. To define the function of these oscillations, we treated cells with repeated short pulses of tumor necrosis factor-alpha at various intervals to mimic pulsatile inflammatory signals. At all pulse intervals that were analyzed, we observed synchronous cycles of NF-kappaB nuclear translocation. Lower frequency stimulations gave repeated full-amplitude translocations, whereas higher frequency pulses gave reduced translocation, indicating a failure to reset. Deterministic and stochastic mathematical models predicted how negative feedback loops regulate both the resetting of the system and cellular heterogeneity. Altering the stimulation intervals gave different patterns of NF-kappaB-dependent gene expression, which supports the idea that oscillation frequency has a functional role.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2785900/" 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/PMC2785900/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ashall, Louise -- Horton, Caroline A -- Nelson, David E -- Paszek, Pawel -- Harper, Claire V -- Sillitoe, Kate -- Ryan, Sheila -- Spiller, David G -- Unitt, John F -- Broomhead, David S -- Kell, Douglas B -- Rand, David A -- See, Violaine -- White, Michael R H -- BB/C007158/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/C008219/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/C520471/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/D010748/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E004210/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E012965/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F005938/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBC0071581/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBC0082191/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBC5204711/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBD0107481/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBF0059381/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0500346/Medical Research Council/United Kingdom -- G0500346(73596)/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):242-6. doi: 10.1126/science.1164860.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Cell Imaging, School of Biological Sciences, Bioscience Research Building, Crown Street, Liverpool, L69 7ZB, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359585" target="_blank"〉PubMed〈/a〉

    Ribosomal protein S6 kinase 1 signaling regulates mammalian life span (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-10-03
    Description: Caloric restriction (CR) protects against aging and disease, but the mechanisms by which this affects mammalian life span are unclear. We show in mice that deletion of ribosomal S6 protein kinase 1 (S6K1), a component of the nutrient-responsive mTOR (mammalian target of rapamycin) signaling pathway, led to increased life span and resistance to age-related pathologies, such as bone, immune, and motor dysfunction and loss of insulin sensitivity. Deletion of S6K1 induced gene expression patterns similar to those seen in CR or with pharmacological activation of adenosine monophosphate (AMP)-activated protein kinase (AMPK), a conserved regulator of the metabolic response to CR. Our results demonstrate that S6K1 influences healthy mammalian life-span and suggest that therapeutic manipulation of S6K1 and AMPK might mimic CR and could provide broad protection against diseases of aging.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Selman, Colin -- Tullet, Jennifer M A -- Wieser, Daniela -- Irvine, Elaine -- Lingard, Steven J -- Choudhury, Agharul I -- Claret, Marc -- Al-Qassab, Hind -- Carmignac, Danielle -- Ramadani, Faruk -- Woods, Angela -- Robinson, Iain C A -- Schuster, Eugene -- Batterham, Rachel L -- Kozma, Sara C -- Thomas, George -- Carling, David -- Okkenhaug, Klaus -- Thornton, Janet M -- Partridge, Linda -- Gems, David -- Withers, Dominic J -- BBS/E/B/0000C236/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/E/B/0000M979/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0800339/Medical Research Council/United Kingdom -- G108/551/Medical Research Council/United Kingdom -- MC_U117531708/Medical Research Council/United Kingdom -- MC_U120027537/Medical Research Council/United Kingdom -- MC_U120097114/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):140-4. doi: 10.1126/science.1177221.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Healthy Ageing, Centre for Diabetes and Endocrinology, Department of Medicine, University College London, London WC1E 6JJ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19797661" target="_blank"〉PubMed〈/a〉

    Neurokinin 1 receptor antagonism as a possible therapy for alcoholism (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-02-16
    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.

    Structural basis of transcription: backtracked RNA polymerase II at 3.4 angstrom resolution (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-05-30
    Description: Transcribing RNA polymerases oscillate between three stable states, two of which, pre- and posttranslocated, were previously subjected to x-ray crystal structure determination. We report here the crystal structure of RNA polymerase II in the third state, the reverse translocated, or "backtracked" state. The defining feature of the backtracked structure is a binding site for the first backtracked nucleotide. This binding site is occupied in case of nucleotide misincorporation in the RNA or damage to the DNA, and is termed the "P" site because it supports proofreading. The predominant mechanism of proofreading is the excision of a dinucleotide in the presence of the elongation factor SII (TFIIS). Structure determination of a cocrystal with TFIIS reveals a rearrangement whereby cleavage of the RNA may take place.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2718261/" 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/PMC2718261/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Dong -- Bushnell, David A -- Huang, Xuhui -- Westover, Kenneth D -- Levitt, Michael -- Kornberg, Roger D -- GM036559/GM/NIGMS NIH HHS/ -- GM041455/GM/NIGMS NIH HHS/ -- GM049985/GM/NIGMS NIH HHS/ -- K99 GM085136/GM/NIGMS NIH HHS/ -- K99 GM085136-01/GM/NIGMS NIH HHS/ -- R00 GM085136/GM/NIGMS NIH HHS/ -- R01 GM036659/GM/NIGMS NIH HHS/ -- R01 GM041455/GM/NIGMS NIH HHS/ -- R01 GM049985/GM/NIGMS NIH HHS/ -- R01 GM049985-16/GM/NIGMS NIH HHS/ -- R37 GM036659/GM/NIGMS NIH HHS/ -- R37 GM036659-22/GM/NIGMS NIH HHS/ -- R37 GM041455/GM/NIGMS NIH HHS/ -- R37 GM041455-20/GM/NIGMS NIH HHS/ -- U54 GM072970/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 May 29;324(5931):1203-6. doi: 10.1126/science.1168729.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Biology, Stanford University School of Medicine, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19478184" target="_blank"〉PubMed〈/a〉

    Solution nuclear magnetic resonance structure of membrane-integral diacylglycerol kinase (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-06-27
    Description: Escherichia coli diacylglycerol kinase (DAGK) represents a family of integral membrane enzymes that is unrelated to all other phosphotransferases. We have determined the three-dimensional structure of the DAGK homotrimer with the use of solution nuclear magnetic resonance. The third transmembrane helix from each subunit is domain-swapped with the first and second transmembrane segments from an adjacent subunit. Each of DAGK's three active sites resembles a portico. The cornice of the portico appears to be the determinant of DAGK's lipid substrate specificity and overhangs the site of phosphoryl transfer near the water-membrane interface. Mutations to cysteine that caused severe misfolding were located in or near the active site, indicating a high degree of overlap between sites responsible for folding and for catalysis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2764269/" 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/PMC2764269/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van Horn, Wade D -- Kim, Hak-Jun -- Ellis, Charles D -- Hadziselimovic, Arina -- Sulistijo, Endah S -- Karra, Murthy D -- Tian, Changlin -- Sonnichsen, Frank D -- Sanders, Charles R -- R01 GM047485/GM/NIGMS NIH HHS/ -- R01 GM047485-17/GM/NIGMS NIH HHS/ -- R01 GM47485/GM/NIGMS NIH HHS/ -- T32 NS007491/NS/NINDS NIH HHS/ -- T32 NS007491-09/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jun 26;324(5935):1726-9. doi: 10.1126/science.1171716.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Center for Structural Biology, Vanderbilt University, Nashville, TN 37232, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19556511" target="_blank"〉PubMed〈/a〉

    Description: Most protein phosphatases have little intrinsic substrate specificity, making selective pharmacological inhibition of specific dephosphorylation reactions a challenging problem. In a screen for small molecules that protect cells from endoplasmic reticulum (ER) stress, we identified salubrinal, a selective inhibitor of cellular complexes that dephosphorylate eukaryotic translation initiation factor 2 subunit alpha (eIF2alpha). Salubrinal also blocks eIF2alpha dephosphorylation mediated by a herpes simplex virus protein and inhibits viral replication. These results suggest that selective chemical inhibitors of eIF2alpha dephosphorylation may be useful in diseases involving ER stress or viral infection. More broadly, salubrinal demonstrates the feasibility of selective pharmacological targeting of cellular dephosphorylation events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boyce, Michael -- Bryant, Kevin F -- Jousse, Celine -- Long, Kai -- Harding, Heather P -- Scheuner, Donalyn -- Kaufman, Randal J -- Ma, Dawei -- Coen, Donald M -- Ron, David -- Yuan, Junying -- AI19838/AI/NIAID NIH HHS/ -- AI26077/AI/NIAID NIH HHS/ -- DDK42394/DK/NIDDK NIH HHS/ -- DK47119/DK/NIDDK NIH HHS/ -- ES08681/ES/NIEHS NIH HHS/ -- GM64703/GM/NIGMS NIH HHS/ -- NS35138/NS/NINDS NIH HHS/ -- R37-AG012859/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2005 Feb 11;307(5711):935-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15705855" target="_blank"〉PubMed〈/a〉

    Sequence variants in SLITRK1 are associated with Tourette's syndrome (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-10-15
    Description: Tourette's syndrome (TS) is a genetically influenced developmental neuropsychiatric disorder characterized by chronic vocal and motor tics. We studied Slit and Trk-like 1 (SLITRK1) as a candidate gene on chromosome 13q31.1 because of its proximity to a de novo chromosomal inversion in a child with TS. Among 174 unrelated probands, we identified a frameshift mutation and two independent occurrences of the identical variant in the binding site for microRNA hsa-miR-189. These variants were absent from 3600 control chromosomes. SLITRK1 mRNA and hsa-miR-189 showed an overlapping expression pattern in brain regions previously implicated in TS. Wild-type SLITRK1, but not the frameshift mutant, enhanced dendritic growth in primary neuronal cultures. Collectively, these findings support the association of rare SLITRK1 sequence variants with TS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abelson, Jesse F -- Kwan, Kenneth Y -- O'Roak, Brian J -- Baek, Danielle Y -- Stillman, Althea A -- Morgan, Thomas M -- Mathews, Carol A -- Pauls, David L -- Rasin, Mladen-Roko -- Gunel, Murat -- Davis, Nicole R -- Ercan-Sencicek, A Gulhan -- Guez, Danielle H -- Spertus, John A -- Leckman, James F -- Dure, Leon S 4th -- Kurlan, Roger -- Singer, Harvey S -- Gilbert, Donald L -- Farhi, Anita -- Louvi, Angeliki -- Lifton, Richard P -- Sestan, Nenad -- State, Matthew W -- K23 RR16118/RR/NCRR NIH HHS/ -- R01 NS054273/NS/NINDS NIH HHS/ -- R01 NS43520/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2005 Oct 14;310(5746):317-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Child Study Center, Yale University School of Medicine, New Haven, CT 06520, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16224024" target="_blank"〉PubMed〈/a〉
