    Beschreibung: The high degree of similarity between the mouse and human genomes is demonstrated through analysis of the sequence of mouse chromosome 16 (Mmu 16), which was obtained as part of a whole-genome shotgun assembly of the mouse genome. The mouse genome is about 10% smaller than the human genome, owing to a lower repetitive DNA content. Comparison of the structure and protein-coding potential of Mmu 16 with that of the homologous segments of the human genome identifies regions of conserved synteny with human chromosomes (Hsa) 3, 8, 12, 16, 21, and 22. Gene content and order are highly conserved between Mmu 16 and the syntenic blocks of the human genome. Of the 731 predicted genes on Mmu 16, 509 align with orthologs on the corresponding portions of the human genome, 44 are likely paralogous to these genes, and 164 genes have homologs elsewhere in the human genome; there are 14 genes for which we could find no human counterpart.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mural, Richard J -- Adams, Mark D -- Myers, Eugene W -- Smith, Hamilton O -- Miklos, George L Gabor -- Wides, Ron -- Halpern, Aaron -- Li, Peter W -- Sutton, Granger G -- Nadeau, Joe -- Salzberg, Steven L -- Holt, Robert A -- Kodira, Chinnappa D -- Lu, Fu -- Chen, Lin -- Deng, Zuoming -- Evangelista, Carlos C -- Gan, Weiniu -- Heiman, Thomas J -- Li, Jiayin -- Li, Zhenya -- Merkulov, Gennady V -- Milshina, Natalia V -- Naik, Ashwinikumar K -- Qi, Rong -- Shue, Bixiong Chris -- Wang, Aihui -- Wang, Jian -- Wang, Xin -- Yan, Xianghe -- Ye, Jane -- Yooseph, Shibu -- Zhao, Qi -- Zheng, Liansheng -- Zhu, Shiaoping C -- Biddick, Kendra -- Bolanos, Randall -- Delcher, Arthur L -- Dew, Ian M -- Fasulo, Daniel -- Flanigan, Michael J -- Huson, Daniel H -- Kravitz, Saul A -- Miller, Jason R -- Mobarry, Clark M -- Reinert, Knut -- Remington, Karin A -- Zhang, Qing -- Zheng, Xiangqun H -- Nusskern, Deborah R -- Lai, Zhongwu -- Lei, Yiding -- Zhong, Wenyan -- Yao, Alison -- Guan, Ping -- Ji, Rui-Ru -- Gu, Zhiping -- Wang, Zhen-Yuan -- Zhong, Fei -- Xiao, Chunlin -- Chiang, Chia-Chien -- Yandell, Mark -- Wortman, Jennifer R -- Amanatides, Peter G -- Hladun, Suzanne L -- Pratts, Eric C -- Johnson, Jeffery E -- Dodson, Kristina L -- Woodford, Kerry J -- Evans, Cheryl A -- Gropman, Barry -- Rusch, Douglas B -- Venter, Eli -- Wang, Mei -- Smith, Thomas J -- Houck, Jarrett T -- Tompkins, Donald E -- Haynes, Charles -- Jacob, Debbie -- Chin, Soo H -- Allen, David R -- Dahlke, Carl E -- Sanders, Robert -- Li, Kelvin -- Liu, Xiangjun -- Levitsky, Alexander A -- Majoros, William H -- Chen, Quan -- Xia, Ashley C -- Lopez, John R -- Donnelly, Michael T -- Newman, Matthew H -- Glodek, Anna -- Kraft, Cheryl L -- Nodell, Marc -- Ali, Feroze -- An, Hui-Jin -- Baldwin-Pitts, Danita -- Beeson, Karen Y -- Cai, Shuang -- Carnes, Mark -- Carver, Amy -- Caulk, Parris M -- Center, Angela -- Chen, Yen-Hui -- Cheng, Ming-Lai -- Coyne, My D -- Crowder, Michelle -- Danaher, Steven -- Davenport, Lionel B -- Desilets, Raymond -- Dietz, Susanne M -- Doup, Lisa -- Dullaghan, Patrick -- Ferriera, Steven -- Fosler, Carl R -- Gire, Harold C -- Gluecksmann, Andres -- Gocayne, Jeannine D -- Gray, Jonathan -- Hart, Brit -- Haynes, Jason -- Hoover, Jeffery -- Howland, Tim -- Ibegwam, Chinyere -- Jalali, Mena -- Johns, David -- Kline, Leslie -- Ma, Daniel S -- MacCawley, Steven -- Magoon, Anand -- Mann, Felecia -- May, David -- McIntosh, Tina C -- Mehta, Somil -- Moy, Linda -- Moy, Mee C -- Murphy, Brian J -- Murphy, Sean D -- Nelson, Keith A -- Nuri, Zubeda -- Parker, Kimberly A -- Prudhomme, Alexandre C -- Puri, Vinita N -- Qureshi, Hina -- Raley, John C -- Reardon, Matthew S -- Regier, Megan A -- Rogers, Yu-Hui C -- Romblad, Deanna L -- Schutz, Jakob -- Scott, John L -- Scott, Richard -- Sitter, Cynthia D -- Smallwood, Michella -- Sprague, Arlan C -- Stewart, Erin -- Strong, Renee V -- Suh, Ellen -- Sylvester, Karena -- Thomas, Reginald -- Tint, Ni Ni -- Tsonis, Christopher -- Wang, Gary -- Wang, George -- Williams, Monica S -- Williams, Sherita M -- Windsor, Sandra M -- Wolfe, Keriellen -- Wu, Mitchell M -- Zaveri, Jayshree -- Chaturvedi, Kabir -- Gabrielian, Andrei E -- Ke, Zhaoxi -- Sun, Jingtao -- Subramanian, Gangadharan -- Venter, J Craig -- Pfannkoch, Cynthia M -- Barnstead, Mary -- Stephenson, Lisa D -- New York, N.Y. -- Science. 2002 May 31;296(5573):1661-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Celera Genomics, 45 West Gude Drive, Rockville, MD 20850, USA. richard.mural@celera.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12040188" target="_blank"〉PubMed〈/a〉

    Beschreibung: 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.

    Beschreibung: The protein-protein interaction between leukocyte functional antigen-1 (LFA-1) and intercellular adhesion molecule-1 (ICAM-1) is critical to lymphocyte and immune system function. Here, we report on the transfer of the contiguous, nonlinear epitope of ICAM-1, responsible for its association with LFA-1, to a small-molecule framework. These LFA-1 antagonists bound LFA-1, blocked binding of ICAM-1, and inhibited a mixed lymphocyte reaction (MLR) with potency significantly greater than that of cyclosporine A. Furthermore, in comparison to an antibody to LFA-1, they exhibited significant anti-inflammatory effects in vivo. These results demonstrate the utility of small-molecule mimics of nonlinear protein epitopes and the protein epitopes themselves as leads in the identification of novel pharmaceutical agents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gadek, T R -- Burdick, D J -- McDowell, R S -- Stanley, M S -- Marsters, J C Jr -- Paris, K J -- Oare, D A -- Reynolds, M E -- Ladner, C -- Zioncheck, K A -- Lee, W P -- Gribling, P -- Dennis, M S -- Skelton, N J -- Tumas, D B -- Clark, K R -- Keating, S M -- Beresini, M H -- Tilley, J W -- Presta, L G -- Bodary, S C -- New York, N.Y. -- Science. 2002 Feb 8;295(5557):1086-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bioorganic Chemistry, Genentech, One DNA Way, South San Francisco, CA 94080, USA. trg@gene.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11834839" target="_blank"〉PubMed〈/a〉

    Beschreibung: The hypoxia-inducible factors (HIFs) 1alpha and 2alpha are key mammalian transcription factors that exhibit dramatic increases in both protein stability and intrinsic transcriptional potency during low-oxygen stress. This increased stability is due to the absence of proline hydroxylation, which in normoxia promotes binding of HIF to the von Hippel-Lindau (VHL tumor suppressor) ubiquitin ligase. We now show that hypoxic induction of the COOH-terminal transactivation domain (CAD) of HIF occurs through abrogation of hydroxylation of a conserved asparagine in the CAD. Inhibitors of Fe(II)- and 2-oxoglutarate-dependent dioxygenases prevented hydroxylation of the Asn, thus allowing the CAD to interact with the p300 transcription coactivator. Replacement of the conserved Asn by Ala resulted in constitutive p300 interaction and strong transcriptional activity. Full induction of HIF-1alpha and -2alpha, therefore, relies on the abrogation of both Pro and Asn hydroxylation, which during normoxia occur at the degradation and COOH-terminal transactivation domains, respectively.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lando, David -- Peet, Daniel J -- Whelan, Dean A -- Gorman, Jeffrey J -- Whitelaw, Murray L -- New York, N.Y. -- Science. 2002 Feb 1;295(5556):858-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biosciences (Biochemistry), Adelaide University, SA 5005, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11823643" target="_blank"〉PubMed〈/a〉

    Beschreibung: Previous studies have revealed that autoantibodies, complement components, and Fc receptors each participate in the pathogenesis of erosive arthritis in K/BxN mice. However, it is not known which cellular populations are responsive to these inflammatory signals. We find that two strains of mice deficient in mast cells, W/Wv and Sl/Sld, were resistant to development of joint inflammation and that susceptibility was restored in the W/Wv strain by mast cell engraftment. Thus, mast cells may function as a cellular link between autoantibodies, soluble mediators, and other effector populations in inflammatory arthritis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, David M -- Friend, Daniel S -- Gurish, Michael F -- Benoist, Christophe -- Mathis, Diane -- Brenner, Michael B -- 1R01 AR/AI46580-01/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2002 Sep 6;297(5587):1689-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12215644" target="_blank"〉PubMed〈/a〉

    Beschreibung: The enzyme alpha1,3-galactosyltransferase (alpha1,3GT or GGTA1) synthesizes alpha1,3-galactose (alpha1,3Gal) epitopes (Galalpha1,3Galbeta1,4GlcNAc-R), which are the major xenoantigens causing hyperacute rejection in pig-to-human xenotransplantation. Complete removal of alpha1,3Gal from pig organs is the critical step toward the success of xenotransplantation. We reported earlier the targeted disruption of one allele of the alpha1,3GT gene in cloned pigs. A selection procedure based on a bacterial toxin was used to select for cells in which the second allele of the gene was knocked out. Sequencing analysis demonstrated that knockout of the second allele of the alpha1,3GT gene was caused by a T-to-G single point mutation at the second base of exon 9, which resulted in inactivation of the alpha1,3GT protein. Four healthy alpha1,3GT double-knockout female piglets were produced by three consecutive rounds of cloning. The piglets carrying a point mutation in the alpha1,3GT gene hold significant value, as they would allow production of alpha1,3Gal-deficient pigs free of antibiotic-resistance genes and thus have the potential to make a safer product for human use.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3154759/" 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/PMC3154759/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phelps, Carol J -- Koike, Chihiro -- Vaught, Todd D -- Boone, Jeremy -- Wells, Kevin D -- Chen, Shu-Hung -- Ball, Suyapa -- Specht, Susan M -- Polejaeva, Irina A -- Monahan, Jeff A -- Jobst, Pete M -- Sharma, Sugandha B -- Lamborn, Ashley E -- Garst, Amy S -- Moore, Marilyn -- Demetris, Anthony J -- Rudert, William A -- Bottino, Rita -- Bertera, Suzanne -- Trucco, Massimo -- Starzl, Thomas E -- Dai, Yifan -- Ayares, David L -- DK29961/DK/NIDDK NIH HHS/ -- R01 AM007772/AM/NIADDK NIH HHS/ -- R01 DK029961-19/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2003 Jan 17;299(5605):411-4.

    Beschreibung: Higher order chromatin structure presents a barrier to the recognition and repair of DNA damage. Double-strand breaks (DSBs) induce histone H2AX phosphorylation, which is associated with the recruitment of repair factors to damaged DNA. To help clarify the physiological role of H2AX, we targeted H2AX in mice. Although H2AX is not essential for irradiation-induced cell-cycle checkpoints, H2AX-/- mice were radiation sensitive, growth retarded, and immune deficient, and mutant males were infertile. These pleiotropic phenotypes were associated with chromosomal instability, repair defects, and impaired recruitment of Nbs1, 53bp1, and Brca1, but not Rad51, to irradiation-induced foci. Thus, H2AX is critical for facilitating the assembly of specific DNA-repair complexes on damaged DNA.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4721576/" 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/PMC4721576/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Celeste, Arkady -- Petersen, Simone -- Romanienko, Peter J -- Fernandez-Capetillo, Oscar -- Chen, Hua Tang -- Sedelnikova, Olga A -- Reina-San-Martin, Bernardo -- Coppola, Vincenzo -- Meffre, Eric -- Difilippantonio, Michael J -- Redon, Christophe -- Pilch, Duane R -- Olaru, Alexandru -- Eckhaus, Michael -- Camerini-Otero, R Daniel -- Tessarollo, Lino -- Livak, Ferenc -- Manova, Katia -- Bonner, William M -- Nussenzweig, Michel C -- Nussenzweig, Andre -- Z99 CA999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2002 May 3;296(5569):922-7.

    Beschreibung: Constitutive Hedgehog (Hh) pathway activity is associated with initiation of neoplasia, but its role in the continued growth of established tumors is unclear. Here, we investigate the therapeutic efficacy of the Hh pathway antagonist cyclopamine in preclinical models of medulloblastoma, the most common malignant brain tumor in children. Cyclopamine treatment of murine medulloblastoma cells blocked proliferation in vitro and induced changes in gene expression consistent with initiation of neuronal differentiation and loss of neuronal stem cell-like character. This compound also caused regression of murine tumor allografts in vivo and induced rapid death of cells from freshly resected human medulloblastomas, but not from other brain tumors, thus establishing a specific role for Hh pathway activity in medulloblastoma growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berman, David M -- Karhadkar, Sunil S -- Hallahan, Andrew R -- Pritchard, Joel I -- Eberhart, Charles G -- Watkins, D Neil -- Chen, James K -- Cooper, Michael K -- Taipale, Jussi -- Olson, James M -- Beachy, Philip A -- New York, N.Y. -- Science. 2002 Aug 30;297(5586):1559-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Genetics, 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/12202832" target="_blank"〉PubMed〈/a〉

    Beschreibung: To explore neuronal mechanisms underlying long-term consequences of stress, we studied stress-induced changes in the neuritic translocation of acetylcholinesterase (AChE) splice variants. Under normal conditions, we found the synaptic AChE-S mRNA and protein in neurites. Corticosterone, anticholinesterases, and forced swim, each facilitated a rapid (minutes), yet long-lasting (weeks), shift from AChE-S to the normally rare AChE-R mRNA, promoted AChE-R mRNA translocation into neurites, and induced enzyme secretion. Weeks after stress, electrophysiological measurements in hippocampus slices displayed apparently normal evoked synaptic responses but extreme hypersensitivity to both anticholinesterases and atropine. Our findings suggest that neuronal hypersensitivity under stress involves neuritic replacement of AChE-S with AChE-R.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meshorer, Eran -- Erb, Christina -- Gazit, Roi -- Pavlovsky, Lev -- Kaufer, Daniela -- Friedman, Alon -- Glick, David -- Ben-Arie, Nissim -- Soreq, Hermona -- New York, N.Y. -- Science. 2002 Jan 18;295(5554):508-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, The Institute of Life Sciences and The Eric Roland Center for Neurodegenerative Diseases, The Hebrew University of Jerusalem, Israel 91904.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11799248" target="_blank"〉PubMed〈/a〉

    Beschreibung: Helicobacter pylori adherence in the human gastric mucosa involves specific bacterial adhesins and cognate host receptors. Here, we identify sialyl-dimeric-Lewis x glycosphingolipid as a receptor for H. pylori and show that H. pylori infection induced formation of sialyl-Lewis x antigens in gastric epithelium in humans and in a Rhesus monkey. The corresponding sialic acid-binding adhesin (SabA) was isolated with the "retagging" method, and the underlying sabA gene (JHP662/HP0725) was identified. The ability of many H. pylori strains to adhere to sialylated glycoconjugates expressed during chronic inflammation might thus contribute to virulence and the extraordinary chronicity of H. pylori infection.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2570540/" 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/PMC2570540/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mahdavi, Jafar -- Sonden, Berit -- Hurtig, Marina -- Olfat, Farzad O -- Forsberg, Lina -- Roche, Niamh -- Angstrom, Jonas -- Larsson, Thomas -- Teneberg, Susann -- Karlsson, Karl-Anders -- Altraja, Siiri -- Wadstrom, Torkel -- Kersulyte, Dangeruta -- Berg, Douglas E -- Dubois, Andre -- Petersson, Christoffer -- Magnusson, Karl-Eric -- Norberg, Thomas -- Lindh, Frank -- Lundskog, Bertil B -- Arnqvist, Anna -- Hammarstrom, Lennart -- Boren, Thomas -- P30 DK52574/DK/NIDDK NIH HHS/ -- R01 AI38166/AI/NIAID NIH HHS/ -- R01 CA082312/CA/NCI NIH HHS/ -- R01 CA082312-08/CA/NCI NIH HHS/ -- R01 DK53727/DK/NIDDK NIH HHS/ -- R03 AI49161/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2002 Jul 26;297(5581):573-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Odontology/Oral Microbiology, Umea University, SE-901 87 Umea, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12142529" target="_blank"〉PubMed〈/a〉
