    Description: The 2,272,351-base pair genome of Neisseria meningitidis strain MC58 (serogroup B), a causative agent of meningitis and septicemia, contains 2158 predicted coding regions, 1158 (53.7%) of which were assigned a biological role. Three major islands of horizontal DNA transfer were identified; two of these contain genes encoding proteins involved in pathogenicity, and the third island contains coding sequences only for hypothetical proteins. Insights into the commensal and virulence behavior of N. meningitidis can be gleaned from the genome, in which sequences for structural proteins of the pilus are clustered and several coding regions unique to serogroup B capsular polysaccharide synthesis can be identified. Finally, N. meningitidis contains more genes that undergo phase variation than any pathogen studied to date, a mechanism that controls their expression and contributes to the evasion of the host immune system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tettelin, H -- Saunders, N J -- Heidelberg, J -- Jeffries, A C -- Nelson, K E -- Eisen, J A -- Ketchum, K A -- Hood, D W -- Peden, J F -- Dodson, R J -- Nelson, W C -- Gwinn, M L -- DeBoy, R -- Peterson, J D -- Hickey, E K -- Haft, D H -- Salzberg, S L -- White, O -- Fleischmann, R D -- Dougherty, B A -- Mason, T -- Ciecko, A -- Parksey, D S -- Blair, E -- Cittone, H -- Clark, E B -- Cotton, M D -- Utterback, T R -- Khouri, H -- Qin, H -- Vamathevan, J -- Gill, J -- Scarlato, V -- Masignani, V -- Pizza, M -- Grandi, G -- Sun, L -- Smith, H O -- Fraser, C M -- Moxon, E R -- Rappuoli, R -- Venter, J C -- New York, N.Y. -- Science. 2000 Mar 10;287(5459):1809-15.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research (TIGR), 9712 Medical Center Drive, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10710307" target="_blank"〉PubMed〈/a〉

    Description: DNA sequence and annotation of the entire human chromosome 7, encompassing nearly 158 million nucleotides of DNA and 1917 gene structures, are presented. To generate a higher order description, additional structural features such as imprinted genes, fragile sites, and segmental duplications were integrated at the level of the DNA sequence with medical genetic data, including 440 chromosome rearrangement breakpoints associated with disease. This approach enabled the discovery of candidate genes for developmental diseases including autism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2882961/" 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/PMC2882961/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scherer, Stephen W -- Cheung, Joseph -- MacDonald, Jeffrey R -- Osborne, Lucy R -- Nakabayashi, Kazuhiko -- Herbrick, Jo-Anne -- Carson, Andrew R -- Parker-Katiraee, Layla -- Skaug, Jennifer -- Khaja, Razi -- Zhang, Junjun -- Hudek, Alexander K -- Li, Martin -- Haddad, May -- Duggan, Gavin E -- Fernandez, Bridget A -- Kanematsu, Emiko -- Gentles, Simone -- Christopoulos, Constantine C -- Choufani, Sanaa -- Kwasnicka, Dorota -- Zheng, Xiangqun H -- Lai, Zhongwu -- Nusskern, Deborah -- Zhang, Qing -- Gu, Zhiping -- Lu, Fu -- Zeesman, Susan -- Nowaczyk, Malgorzata J -- Teshima, Ikuko -- Chitayat, David -- Shuman, Cheryl -- Weksberg, Rosanna -- Zackai, Elaine H -- Grebe, Theresa A -- Cox, Sarah R -- Kirkpatrick, Susan J -- Rahman, Nazneen -- Friedman, Jan M -- Heng, Henry H Q -- Pelicci, Pier Giuseppe -- Lo-Coco, Francesco -- Belloni, Elena -- Shaffer, Lisa G -- Pober, Barbara -- Morton, Cynthia C -- Gusella, James F -- Bruns, Gail A P -- Korf, Bruce R -- Quade, Bradley J -- Ligon, Azra H -- Ferguson, Heather -- Higgins, Anne W -- Leach, Natalia T -- Herrick, Steven R -- Lemyre, Emmanuelle -- Farra, Chantal G -- Kim, Hyung-Goo -- Summers, Anne M -- Gripp, Karen W -- Roberts, Wendy -- Szatmari, Peter -- Winsor, Elizabeth J T -- Grzeschik, Karl-Heinz -- Teebi, Ahmed -- Minassian, Berge A -- Kere, Juha -- Armengol, Lluis -- Pujana, Miguel Angel -- Estivill, Xavier -- Wilson, Michael D -- Koop, Ben F -- Tosi, Sabrina -- Moore, Gudrun E -- Boright, Andrew P -- Zlotorynski, Eitan -- Kerem, Batsheva -- Kroisel, Peter M -- Petek, Erwin -- Oscier, David G -- Mould, Sarah J -- Dohner, Hartmut -- Dohner, Konstanze -- Rommens, Johanna M -- Vincent, John B -- Venter, J Craig -- Li, Peter W -- Mural, Richard J -- Adams, Mark D -- Tsui, Lap-Chee -- 38103/Canadian Institutes of Health Research/Canada -- P01 GM061354/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 May 2;300(5620):767-72.

    Description: Rapid adaptive fixation of a new favorable mutation is expected to affect neighboring genes along the chromosome. Evolutionary theory predicts that the chromosomal region would show a reduced level of genetic variation and an excess of rare alleles. We have confirmed these predictions in a region of the X chromosome of Drosophila melanogaster that contains a newly evolved gene for a component of the sperm axoneme. In D. simulans, where the novel gene does not exist, the pattern of genetic variation is consistent with selection against recurrent deleterious mutations. These findings imply that the pattern of genetic variation along a chromosome may be useful for inferring its evolutionary history and for revealing regions in which recent adaptive fixations have taken place.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nurminsky, D -- Aguiar, D D -- Bustamante, C D -- Hartl, D L -- GM 60035/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 Jan 5;291(5501):128-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Cell Biology, Tufts University School of Medicine, 136 Harrison Avenue, Boston, MA 02111, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11141564" target="_blank"〉PubMed〈/a〉

    Description: The mechanisms controlling axon guidance are of fundamental importance in understanding brain development. Growing corticospinal and somatosensory axons cross the midline in the medulla to reach their targets and thus form the basis of contralateral motor control and sensory input. The motor and sensory projections appeared uncrossed in patients with horizontal gaze palsy with progressive scoliosis (HGPPS). In patients affected with HGPPS, we identified mutations in the ROBO3 gene, which shares homology with roundabout genes important in axon guidance in developing Drosophila, zebrafish, and mouse. Like its murine homolog Rig1/Robo3, but unlike other Robo proteins, ROBO3 is required for hindbrain axon midline crossing.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1618874/" 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/PMC1618874/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jen, Joanna C -- Chan, Wai-Man -- Bosley, Thomas M -- Wan, Jijun -- Carr, Janai R -- Rub, Udo -- Shattuck, David -- Salamon, Georges -- Kudo, Lili C -- Ou, Jing -- Lin, Doris D M -- Salih, Mustafa A M -- Kansu, Tulay -- Al Dhalaan, Hesham -- Al Zayed, Zayed -- MacDonald, David B -- Stigsby, Bent -- Plaitakis, Andreas -- Dretakis, Emmanuel K -- Gottlob, Irene -- Pieh, Christina -- Traboulsi, Elias I -- Wang, Qing -- Wang, Lejin -- Andrews, Caroline -- Yamada, Koki -- Demer, Joseph L -- Karim, Shaheen -- Alger, Jeffry R -- Geschwind, Daniel H -- Deller, Thomas -- Sicotte, Nancy L -- Nelson, Stanley F -- Baloh, Robert W -- Engle, Elizabeth C -- DC00162/DC/NIDCD NIH HHS/ -- DC05524/DC/NIDCD NIH HHS/ -- EY12498/EY/NEI NIH HHS/ -- EY13583/EY/NEI NIH HHS/ -- EY15298/EY/NEI NIH HHS/ -- EY15311/EY/NEI NIH HHS/ -- MH60233/MH/NIMH NIH HHS/ -- P30 HD 18655/HD/NICHD NIH HHS/ -- R01 EY008313/EY/NEI NIH HHS/ -- R01 EY008313-14/EY/NEI NIH HHS/ -- R01 HL066251/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2004 Jun 4;304(5676):1509-13.

    Description: Extracts of the resin of the guggul tree (Commiphora mukul) lower LDL (low-density lipoprotein) cholesterol levels in humans. The plant sterol guggulsterone [4,17(20)-pregnadiene-3,16-dione] is the active agent in this extract. We show that guggulsterone is a highly efficacious antagonist of the farnesoid X receptor (FXR), a nuclear hormone receptor that is activated by bile acids. Guggulsterone treatment decreases hepatic cholesterol in wild-type mice fed a high-cholesterol diet but is not effective in FXR-null mice. Thus, we propose that inhibition of FXR activation is the basis for the cholesterol-lowering activity of guggulsterone. Other natural products with specific biologic effects may modulate the activity of FXR or other relatively promiscuous nuclear hormone receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Urizar, Nancy L -- Liverman, Amy B -- Dodds, D'Nette T -- Silva, Frank Valentin -- Ordentlich, Peter -- Yan, Yingzhuo -- Gonzalez, Frank J -- Heyman, Richard A -- Mangelsdorf, David J -- Moore, David D -- New York, N.Y. -- Science. 2002 May 31;296(5573):1703-6.

    Description: Over 225,000 independent Agrobacterium transferred DNA (T-DNA) insertion events in the genome of the reference plant Arabidopsis thaliana have been created that represent near saturation of the gene space. The precise locations were determined for more than 88,000 T-DNA insertions, which resulted in the identification of mutations in more than 21,700 of the approximately 29,454 predicted Arabidopsis genes. Genome-wide analysis of the distribution of integration events revealed the existence of a large integration site bias at both the chromosome and gene levels. Insertion mutations were identified in genes that are regulated in response to the plant hormone ethylene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alonso, Jose M -- Stepanova, Anna N -- Leisse, Thomas J -- Kim, Christopher J -- Chen, Huaming -- Shinn, Paul -- Stevenson, Denise K -- Zimmerman, Justin -- Barajas, Pascual -- Cheuk, Rosa -- Gadrinab, Carmelita -- Heller, Collen -- Jeske, Albert -- Koesema, Eric -- Meyers, Cristina C -- Parker, Holly -- Prednis, Lance -- Ansari, Yasser -- Choy, Nathan -- Deen, Hashim -- Geralt, Michael -- Hazari, Nisha -- Hom, Emily -- Karnes, Meagan -- Mulholland, Celene -- Ndubaku, Ral -- Schmidt, Ian -- Guzman, Plinio -- Aguilar-Henonin, Laura -- Schmid, Markus -- Weigel, Detlef -- Carter, David E -- Marchand, Trudy -- Risseeuw, Eddy -- Brogden, Debra -- Zeko, Albana -- Crosby, William L -- Berry, Charles C -- Ecker, Joseph R -- New York, N.Y. -- Science. 2003 Aug 1;301(5633):653-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genomic Analysis Laboratory, The Salk Institute for Biological Studies, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12893945" target="_blank"〉PubMed〈/a〉

    Description: Signaling by the transcription factor nuclear factor kappa B (NF-kappaB) involves its release from inhibitor kappa B (IkappaB) in the cytosol, followed by translocation into the nucleus. NF-kappaB regulation of IkappaBalpha transcription represents a delayed negative feedback loop that drives oscillations in NF-kappaB translocation. Single-cell time-lapse imaging and computational modeling of NF-kappaB (RelA) localization showed asynchronous oscillations following cell stimulation that decreased in frequency with increased IkappaBalpha transcription. Transcription of target genes depended on oscillation persistence, involving cycles of RelA phosphorylation and dephosphorylation. The functional consequences of NF-kappaB signaling may thus depend on number, period, and amplitude of oscillations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nelson, D E -- Ihekwaba, A E C -- Elliott, M -- Johnson, J R -- Gibney, C A -- Foreman, B E -- Nelson, G -- See, V -- Horton, C A -- Spiller, D G -- Edwards, S W -- McDowell, H P -- Unitt, J F -- Sullivan, E -- Grimley, R -- Benson, N -- Broomhead, D -- Kell, D B -- White, M R H -- New York, N.Y. -- Science. 2004 Oct 22;306(5696):704-8.〈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/15499023" target="_blank"〉PubMed〈/a〉

    Description: Even though human and chimpanzee gene sequences are nearly 99% identical, sequence comparisons can nevertheless be highly informative in identifying biologically important changes that have occurred since our ancestral lineages diverged. We analyzed alignments of 7645 chimpanzee gene sequences to their human and mouse orthologs. These three-species sequence alignments allowed us to identify genes undergoing natural selection along the human and chimp lineage by fitting models that include parameters specifying rates of synonymous and nonsynonymous nucleotide substitution. This evolutionary approach revealed an informative set of genes with significantly different patterns of substitution on the human lineage compared with the chimpanzee and mouse lineages. Partitions of genes into inferred biological classes identified accelerated evolution in several functional classes, including olfaction and nuclear transport. In addition to suggesting adaptive physiological differences between chimps and humans, human-accelerated genes are significantly more likely to underlie major known Mendelian disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clark, Andrew G -- Glanowski, Stephen -- Nielsen, Rasmus -- Thomas, Paul D -- Kejariwal, Anish -- Todd, Melissa A -- Tanenbaum, David M -- Civello, Daniel -- Lu, Fu -- Murphy, Brian -- Ferriera, Steve -- Wang, Gary -- Zheng, Xianqgun -- White, Thomas J -- Sninsky, John J -- Adams, Mark D -- Cargill, Michele -- New York, N.Y. -- Science. 2003 Dec 12;302(5652):1960-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology and Genetics, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14671302" target="_blank"〉PubMed〈/a〉

    Description: We describe the efficacy of L-870812, an inhibitor of HIV-1 and SIV integrase, in rhesus macaques infected with the simian-human immunodeficiency virus (SHIV) 89.6P. When initiated before CD4 cell depletion, L-870812 therapy mediated a sustained suppression of viremia, preserving CD4 levels and permitting the induction of virus-specific cellular immunity. L-870812 was also active in chronic infection; however, the magnitude and durability of the effect varied in conjunction with the pretreatment immune response and viral load. These studies demonstrate integrase inhibitor activity in vivo and suggest that cellular immunity facilitates chemotherapeutic efficacy in retroviral infections.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hazuda, Daria J -- Young, Steven D -- Guare, James P -- Anthony, Neville J -- Gomez, Robert P -- Wai, John S -- Vacca, Joseph P -- Handt, Larry -- Motzel, Sherri L -- Klein, Hilton J -- Dornadula, Geethanjali -- Danovich, Robert M -- Witmer, Marc V -- Wilson, Keith A A -- Tussey, Lynda -- Schleif, William A -- Gabryelski, Lori S -- Jin, Lixia -- Miller, Michael D -- Casimiro, Danilo R -- Emini, Emilio A -- Shiver, John W -- New York, N.Y. -- Science. 2004 Jul 23;305(5683):528-32.
