    Description: The bright, peculiar elliptical galaxy Centaurus A (NGC 5128, PKS 1322-427) was one of the first extragalactic radio sources to be optically identified (Bolton et al. 1949). At a distance of 4 Mpc, Centaurus A is the closest active radio galaxy and affords the highest linear imaging resolution (1 mas approximately equal to 0.02 pc) and hence the best prospects for studying an active nucleus close to the central radio source. We present the results of multi-epoch, 8.4-GHz, very long baseline interferometry (VLBI), imaging observations of the nucleus made over the past three years. The nucleus possesses a core-jet structure where the inner portion of the jet shows apparent linear motion with a velocity substantially less than the speed of light.

    Description: 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〉

    Description: Dendritic cells can capture and transfer retroviruses in vitro across synaptic cell-cell contacts to uninfected cells, a process called trans-infection. Whether trans-infection contributes to retroviral spread in vivo remains unknown. Here, we visualize how retroviruses disseminate in secondary lymphoid tissues of living mice. We demonstrate that murine leukemia virus (MLV) and human immunodeficiency virus (HIV) are first captured by sinus-lining macrophages. CD169/Siglec-1, an I-type lectin that recognizes gangliosides, captures the virus. MLV-laden macrophages then form long-lived synaptic contacts to trans-infect B-1 cells. Infected B-1 cells subsequently migrate into the lymph node to spread the infection through virological synapses. Robust infection in lymph nodes and spleen requires CD169, suggesting that a combination of fluid-based movement followed by CD169-dependent trans-infection can contribute to viral spread.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4651917/" 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/PMC4651917/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sewald, Xaver -- Ladinsky, Mark S -- Uchil, Pradeep D -- Beloor, Jagadish -- Pi, Ruoxi -- Herrmann, Christin -- Motamedi, Nasim -- Murooka, Thomas T -- Brehm, Michael A -- Greiner, Dale L -- Shultz, Leonard D -- Mempel, Thorsten R -- Bjorkman, Pamela J -- Kumar, Priti -- Mothes, Walther -- P01 AI078897/AI/NIAID NIH HHS/ -- P30 CA016359/CA/NCI NIH HHS/ -- P50 GM082545/GM/NIGMS NIH HHS/ -- P50GM082545/GM/NIGMS NIH HHS/ -- R01 AI097052/AI/NIAID NIH HHS/ -- R01 AI112443/AI/NIAID NIH HHS/ -- R01 CA098727/CA/NCI NIH HHS/ -- R01 DA036298/DA/NIDA NIH HHS/ -- S10 RR026697/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2015 Oct 30;350(6260):563-7. doi: 10.1126/science.aab2749.

    Description: CHARGE syndrome is a multiple anomaly disorder in which patients present with a variety of phenotypes, including ocular coloboma, heart defects, choanal atresia, retarded growth and development, genitourinary hypoplasia and ear abnormalities. Despite 70-90% of CHARGE syndrome cases resulting from mutations in the gene CHD7, which encodes an ATP-dependent chromatin remodeller, the pathways underlying the diverse phenotypes remain poorly understood. Surprisingly, our studies of a knock-in mutant mouse strain that expresses a stabilized and transcriptionally dead variant of the tumour-suppressor protein p53 (p53(25,26,53,54)), along with a wild-type allele of p53 (also known as Trp53), revealed late-gestational embryonic lethality associated with a host of phenotypes that are characteristic of CHARGE syndrome, including coloboma, inner and outer ear malformations, heart outflow tract defects and craniofacial defects. We found that the p53(25,26,53,54) mutant protein stabilized and hyperactivated wild-type p53, which then inappropriately induced its target genes and triggered cell-cycle arrest or apoptosis during development. Importantly, these phenotypes were only observed with a wild-type p53 allele, as p53(25,26,53,54)(/-) embryos were fully viable. Furthermore, we found that CHD7 can bind to the p53 promoter, thereby negatively regulating p53 expression, and that CHD7 loss in mouse neural crest cells or samples from patients with CHARGE syndrome results in p53 activation. Strikingly, we found that p53 heterozygosity partially rescued the phenotypes in Chd7-null mouse embryos, demonstrating that p53 contributes to the phenotypes that result from CHD7 loss. Thus, inappropriate p53 activation during development can promote CHARGE phenotypes, supporting the idea that p53 has a critical role in developmental syndromes and providing important insight into the mechanisms underlying CHARGE syndrome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4192026/" 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/PMC4192026/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van Nostrand, Jeanine L -- Brady, Colleen A -- Jung, Heiyoun -- Fuentes, Daniel R -- Kozak, Margaret M -- Johnson, Thomas M -- Lin, Chieh-Yu -- Lin, Chien-Jung -- Swiderski, Donald L -- Vogel, Hannes -- Bernstein, Jonathan A -- Attie-Bitach, Tania -- Chang, Ching-Pin -- Wysocka, Joanna -- Martin, Donna M -- Attardi, Laura D -- 1F31CA167917-01/CA/NCI NIH HHS/ -- F31 CA167917/CA/NCI NIH HHS/ -- R01 CA140875/CA/NCI NIH HHS/ -- R01 DC009410/DC/NIDCD NIH HHS/ -- R01 GM095555/GM/NIGMS NIH HHS/ -- R01 HL118087/HL/NHLBI NIH HHS/ -- R01HL121197/HL/NHLBI NIH HHS/ -- England -- Nature. 2014 Oct 9;514(7521):228-32. doi: 10.1038/nature13585.

    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〉

    Notes: In situ hybridization using nucleic acid probes was used to detect cell- and tissue-specific transcript(s) of embryonic genes during development and differentiation. This highly sensitive technique has the potential to provide valuable information on the regulation of low-abundance housekeeping genes during development. We have determined the experimental conditions required to detect the catalase message in adult mouse liver. Catalase effects the breakdown of H2O2 to O2 and H2O and offers protection against the toxic effects of oxygen radicals. We used a cloned 550 bp BamHI-Pstl fragment from a mouse catalase cDNA (pMCT-1) to generate 35S-labeled sense and antisense riboprobes. The experimental conditions used were sensitive enough to quantitate the abundance of silver grains generated by the antisense riboprobe on the adult liver, a tissue known to be positive for this message. The hybridization protocol was applied to serial sections of 13- and 18-day-old mouse embryos. The results suggest that the catalase expression in the liver and brain begins with somite formation and increases with development and differentiation. On the other hand, this message appears to be absent in mesenchyme, particularly in day 13 embryos. The message in positive tissues appears evenly distributed throughout the cell. The observed expression of the catalase message in the adult liver is approximately six times that in the embryonic liver. It is compatible with the enzyme activity results and emphasizes the sensitivity of the in situ hybridization method (over northern blot, etc.) used in this study.

    Description: Three distinct classes of drugs: dopaminergic agonists (such as D-amphetamine), serotonergic agonists (such as LSD), and glutamatergic antagonists (such as PCP) all induce psychotomimetic states in experimental animals that closely resemble schizophrenia symptoms in humans. Here we implicate a common signaling pathway in mediating these effects. In this pathway, dopamine- and an adenosine 3',5'-monophosphate (cAMP)-regulated phospho-protein of 32 kilodaltons (DARPP-32) is phosphorylated or dephosphorylated at three sites, in a pattern predicted to cause a synergistic inhibition of protein phosphatase-1 and concomitant regulation of its downstream effector proteins glycogen synthesis kinase-3 (GSK-3), cAMP response element-binding protein (CREB), and c-Fos. In mice with a genetic deletion of DARPP-32 or with point mutations in phosphorylation sites of DARPP-32, the effects of D-amphetamine, LSD, and PCP on two behavioral parameters-sensorimotor gating and repetitive movements-were strongly attenuated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Svenningsson, Per -- Tzavara, Eleni T -- Carruthers, Robert -- Rachleff, Ilan -- Wattler, Sigrid -- Nehls, Michael -- McKinzie, David L -- Fienberg, Allen A -- Nomikos, George G -- Greengard, Paul -- DA10044/DA/NIDA NIH HHS/ -- MH40899/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2003 Nov 21;302(5649):1412-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular and Cellular Neuroscience, The Rockefeller University, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14631045" target="_blank"〉PubMed〈/a〉

    Description: A20 is a cytoplasmic zinc finger protein that inhibits nuclear factor kappaB (NF-kappaB) activity and tumor necrosis factor (TNF)-mediated programmed cell death (PCD). TNF dramatically increases A20 messenger RNA expression in all tissues. Mice deficient for A20 develop severe inflammation and cachexia, are hypersensitive to both lipopolysaccharide and TNF, and die prematurely. A20-deficient cells fail to terminate TNF-induced NF-kappaB responses. These cells are also more susceptible than control cells to undergo TNF-mediated PCD. Thus, A20 is critical for limiting inflammation by terminating TNF-induced NF-kappaB responses in vivo.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3582399/" 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/PMC3582399/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, E G -- Boone, D L -- Chai, S -- Libby, S L -- Chien, M -- Lodolce, J P -- Ma, A -- 5T32GM07183/GM/NIGMS NIH HHS/ -- R01 DK052751/DK/NIDDK NIH HHS/ -- T32GM07839/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Sep 29;289(5488):2350-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, The University of Chicago, 5841 South Maryland Avenue, MC 6084, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11009421" target="_blank"〉PubMed〈/a〉
