    Differential use of CREB binding protein-coactivator complexes (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-02-21
    Description: CREB binding protein (CBP) functions as an essential coactivator of transcription factors that are inhibited by the adenovirus early gene product E1A. Transcriptional activation by the signal transducer and activator of transcription-1 (STAT1) protein requires the C/H3 domain in CBP, which is the primary target of E1A inhibition. Here it was found that the C/H3 domain is not required for retinoic acid receptor (RAR) function, nor is it involved in E1A inhibition. Instead, E1A inhibits RAR function by preventing the assembly of CBP-nuclear receptor coactivator complexes, revealing differences in required CBP domains for transcriptional activation by RAR and STAT1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kurokawa, R -- Kalafus, D -- Ogliastro, M H -- Kioussi, C -- Xu, L -- Torchia, J -- Rosenfeld, M G -- Glass, C K -- New York, N.Y. -- Science. 1998 Jan 30;279(5351):700-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cellular and Molecular Medicine, Department of Medicine, University of California, San Diego, 9500 Gilman Drive, La Jolla, CA 92093-0651, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9445474" target="_blank"〉PubMed〈/a〉

    Distinct cellular interactions of secreted and transmembrane Ebola virus glycoproteins (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-03-07
    Description: The mechanisms by which Ebola virus evades detection and infects cells to cause hemorrhagic fever have not been defined, though its glycoprotein, synthesized in either a secreted or transmembrane form, is likely involved. Here the secreted glycoprotein was found to interact with neutrophils through CD16b, the neutrophil-specific form of the Fc gamma receptor III, whereas the transmembrane glycoprotein was found to interact with endothelial cells but not neutrophils. A murine retroviral vector pseudotyped with the transmembrane glycoprotein preferentially infected endothelial cells. Thus, the secreted glycoprotein inhibits early neutrophil activation, which likely affects the host response to infection, whereas binding of the transmembrane glycoprotein to endothelial cells may contribute to the hemorrhagic symptoms of this disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Z -- Delgado, R -- Xu, L -- Todd, R F -- Nabel, E G -- Sanchez, A -- Nabel, G J -- New York, N.Y. -- Science. 1998 Feb 13;279(5353):1034-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Internal Medicine, University of Michigan, Ann Arbor, MI 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9461435" target="_blank"〉PubMed〈/a〉

    Transcription factor-specific requirements for coactivators and their acetyltransferase functions (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-02-21
    Description: Different classes of mammalian transcription factors-nuclear receptors, cyclic adenosine 3',5'-monophosphate-regulated enhancer binding protein (CREB), and signal transducer and activator of transcription-1 (STAT-1)-functionally require distinct components of the coactivator complex, including CREB-binding protein (CBP/p300), nuclear receptor coactivators (NCoAs), and p300/CBP-associated factor (p/CAF), based on their platform or assembly properties. Retinoic acid receptor, CREB, and STAT-1 also require different histone acetyltransferase (HAT) activities to activate transcription. Thus, transcription factor-specific differences in configuration and content of the coactivator complex dictate requirements for specific acetyltransferase activities, providing an explanation, at least in part, for the presence of multiple HAT components of the complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Korzus, E -- Torchia, J -- Rose, D W -- Xu, L -- Kurokawa, R -- McInerney, E M -- Mullen, T M -- Glass, C K -- Rosenfeld, M G -- New York, N.Y. -- Science. 1998 Jan 30;279(5351):703-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of California San Diego (UCSD), 9500 Gilman Drive, La Jolla, CA 92093-0648, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9445475" target="_blank"〉PubMed〈/a〉

    The sequence and de novo assembly of the giant panda genome (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-17
    Description: Using next-generation sequencing technology alone, we have successfully generated and assembled a draft sequence of the giant panda genome. The assembled contigs (2.25 gigabases (Gb)) cover approximately 94% of the whole genome, and the remaining gaps (0.05 Gb) seem to contain carnivore-specific repeats and tandem repeats. Comparisons with the dog and human showed that the panda genome has a lower divergence rate. The assessment of panda genes potentially underlying some of its unique traits indicated that its bamboo diet might be more dependent on its gut microbiome than its own genetic composition. We also identified more than 2.7 million heterozygous single nucleotide polymorphisms in the diploid genome. Our data and analyses provide a foundation for promoting mammalian genetic research, and demonstrate the feasibility for using next-generation sequencing technologies for accurate, cost-effective and rapid de novo assembly of large eukaryotic genomes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951497/" 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/PMC3951497/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Ruiqiang -- Fan, Wei -- Tian, Geng -- Zhu, Hongmei -- He, Lin -- Cai, Jing -- Huang, Quanfei -- Cai, Qingle -- Li, Bo -- Bai, Yinqi -- Zhang, Zhihe -- Zhang, Yaping -- Wang, Wen -- Li, Jun -- Wei, Fuwen -- Li, Heng -- Jian, Min -- Li, Jianwen -- Zhang, Zhaolei -- Nielsen, Rasmus -- Li, Dawei -- Gu, Wanjun -- Yang, Zhentao -- Xuan, Zhaoling -- Ryder, Oliver A -- Leung, Frederick Chi-Ching -- Zhou, Yan -- Cao, Jianjun -- Sun, Xiao -- Fu, Yonggui -- Fang, Xiaodong -- Guo, Xiaosen -- Wang, Bo -- Hou, Rong -- Shen, Fujun -- Mu, Bo -- Ni, Peixiang -- Lin, Runmao -- Qian, Wubin -- Wang, Guodong -- Yu, Chang -- Nie, Wenhui -- Wang, Jinhuan -- Wu, Zhigang -- Liang, Huiqing -- Min, Jiumeng -- Wu, Qi -- Cheng, Shifeng -- Ruan, Jue -- Wang, Mingwei -- Shi, Zhongbin -- Wen, Ming -- Liu, Binghang -- Ren, Xiaoli -- Zheng, Huisong -- Dong, Dong -- Cook, Kathleen -- Shan, Gao -- Zhang, Hao -- Kosiol, Carolin -- Xie, Xueying -- Lu, Zuhong -- Zheng, Hancheng -- Li, Yingrui -- Steiner, Cynthia C -- Lam, Tommy Tsan-Yuk -- Lin, Siyuan -- Zhang, Qinghui -- Li, Guoqing -- Tian, Jing -- Gong, Timing -- Liu, Hongde -- Zhang, Dejin -- Fang, Lin -- Ye, Chen -- Zhang, Juanbin -- Hu, Wenbo -- Xu, Anlong -- Ren, Yuanyuan -- Zhang, Guojie -- Bruford, Michael W -- Li, Qibin -- Ma, Lijia -- Guo, Yiran -- An, Na -- Hu, Yujie -- Zheng, Yang -- Shi, Yongyong -- Li, Zhiqiang -- Liu, Qing -- Chen, Yanling -- Zhao, Jing -- Qu, Ning -- Zhao, Shancen -- Tian, Feng -- Wang, Xiaoling -- Wang, Haiyin -- Xu, Lizhi -- Liu, Xiao -- Vinar, Tomas -- Wang, Yajun -- Lam, Tak-Wah -- Yiu, Siu-Ming -- Liu, Shiping -- Zhang, Hemin -- Li, Desheng -- Huang, Yan -- Wang, Xia -- Yang, Guohua -- Jiang, Zhi -- Wang, Junyi -- Qin, Nan -- Li, Li -- Li, Jingxiang -- Bolund, Lars -- Kristiansen, Karsten -- Wong, Gane Ka-Shu -- Olson, Maynard -- Zhang, Xiuqing -- Li, Songgang -- Yang, Huanming -- Wang, Jian -- Wang, Jun -- R01 HG003229/HG/NHGRI NIH HHS/ -- R01 HG003229-05/HG/NHGRI NIH HHS/ -- England -- Nature. 2010 Jan 21;463(7279):311-7. doi: 10.1038/nature08696.

    Induction of broadly neutralizing H1N1 influenza antibodies by vaccination (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-07-22
    Description: The rapid dissemination of the 2009 pandemic influenza virus underscores the need for universal influenza vaccines that elicit protective immunity to diverse viral strains. Here, we show that vaccination with plasmid DNA encoding H1N1 influenza hemagglutinin (HA) and boosting with seasonal vaccine or replication-defective adenovirus 5 vector encoding HA stimulated the production of broadly neutralizing influenza antibodies. This prime/boost combination increased the neutralization of diverse H1N1 strains dating from 1934 to 2007 as compared to either component alone and conferred protection against divergent H1N1 viruses in mice and ferrets. These antibodies were directed to the conserved stem region of HA and were also elicited in nonhuman primates. Cross-neutralization of H1N1 subtypes elicited by this approach provides a basis for the development of a universal influenza vaccine for humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wei, Chih-Jen -- Boyington, Jeffrey C -- McTamney, Patrick M -- Kong, Wing-Pui -- Pearce, Melissa B -- Xu, Ling -- Andersen, Hanne -- Rao, Srinivas -- Tumpey, Terrence M -- Yang, Zhi-Yong -- Nabel, Gary J -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Aug 27;329(5995):1060-4. doi: 10.1126/science.1192517.

    Rational design of envelope identifies broadly neutralizing human monoclonal antibodies to HIV-1 (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-07-10
    Description: Cross-reactive neutralizing antibodies (NAbs) are found in the sera of many HIV-1-infected individuals, but the virologic basis of their neutralization remains poorly understood. We used knowledge of HIV-1 envelope structure to develop antigenically resurfaced glycoproteins specific for the structurally conserved site of initial CD4 receptor binding. These probes were used to identify sera with NAbs to the CD4-binding site (CD4bs) and to isolate individual B cells from such an HIV-1-infected donor. By expressing immunoglobulin genes from individual cells, we identified three monoclonal antibodies, including a pair of somatic variants that neutralized over 90% of circulating HIV-1 isolates. Exceptionally broad HIV-1 neutralization can be achieved with individual antibodies targeted to the functionally conserved CD4bs of glycoprotein 120, an important insight for future HIV-1 vaccine design.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2965066/" 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/PMC2965066/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Xueling -- Yang, Zhi-Yong -- Li, Yuxing -- Hogerkorp, Carl-Magnus -- Schief, William R -- Seaman, Michael S -- Zhou, Tongqing -- Schmidt, Stephen D -- Wu, Lan -- Xu, Ling -- Longo, Nancy S -- McKee, Krisha -- O'Dell, Sijy -- Louder, Mark K -- Wycuff, Diane L -- Feng, Yu -- Nason, Martha -- Doria-Rose, Nicole -- Connors, Mark -- Kwong, Peter D -- Roederer, Mario -- Wyatt, Richard T -- Nabel, Gary J -- Mascola, John R -- Z99 AI999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Aug 13;329(5993):856-61. doi: 10.1126/science.1187659.

    Description: We report classes of electronic systems that achieve thicknesses, effective elastic moduli, bending stiffnesses, and areal mass densities matched to the epidermis. Unlike traditional wafer-based technologies, laminating such devices onto the skin leads to conformal contact and adequate adhesion based on van der Waals interactions alone, in a manner that is mechanically invisible to the user. We describe systems incorporating electrophysiological, temperature, and strain sensors, as well as transistors, light-emitting diodes, photodetectors, radio frequency inductors, capacitors, oscillators, and rectifying diodes. Solar cells and wireless coils provide options for power supply. We used this type of technology to measure electrical activity produced by the heart, brain, and skeletal muscles and show that the resulting data contain sufficient information for an unusual type of computer game controller.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Dae-Hyeong -- Lu, Nanshu -- Ma, Rui -- Kim, Yun-Soung -- Kim, Rak-Hwan -- Wang, Shuodao -- Wu, Jian -- Won, Sang Min -- Tao, Hu -- Islam, Ahmad -- Yu, Ki Jun -- Kim, Tae-il -- Chowdhury, Raeed -- Ying, Ming -- Xu, Lizhi -- Li, Ming -- Chung, Hyun-Joong -- Keum, Hohyun -- McCormick, Martin -- Liu, Ping -- Zhang, Yong-Wei -- Omenetto, Fiorenzo G -- Huang, Yonggang -- Coleman, Todd -- Rogers, John A -- New York, N.Y. -- Science. 2011 Aug 12;333(6044):838-43. doi: 10.1126/science.1206157.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Materials Science and Engineering, Beckman Institute for Advanced Science and Technology, and Frederick Seitz Materials Research Laboratory, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21836009" target="_blank"〉PubMed〈/a〉

    Probing meiotic recombination and aneuploidy of single sperm cells by whole-genome sequencing (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-22
    Description: Meiotic recombination creates genetic diversity and ensures segregation of homologous chromosomes. Previous population analyses yielded results averaged among individuals and affected by evolutionary pressures. We sequenced 99 sperm from an Asian male by using the newly developed amplification method-multiple annealing and looping-based amplification cycles-to phase the personal genome and map recombination events at high resolution, which are nonuniformly distributed across the genome in the absence of selection pressure. The paucity of recombination near transcription start sites observed in individual sperm indicates that such a phenomenon is intrinsic to the molecular mechanism of meiosis. Interestingly, a decreased crossover frequency combined with an increase of autosomal aneuploidy is observable on a global per-sperm basis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3590491/" 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/PMC3590491/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lu, Sijia -- Zong, Chenghang -- Fan, Wei -- Yang, Mingyu -- Li, Jinsen -- Chapman, Alec R -- Zhu, Ping -- Hu, Xuesong -- Xu, Liya -- Yan, Liying -- Bai, Fan -- Qiao, Jie -- Tang, Fuchou -- Li, Ruiqiang -- Xie, X Sunney -- HG005097-1/HG/NHGRI NIH HHS/ -- HG005613-01/HG/NHGRI NIH HHS/ -- R01 HG005097/HG/NHGRI NIH HHS/ -- RC2 HG005613/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2012 Dec 21;338(6114):1627-30. doi: 10.1126/science.1229112.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23258895" target="_blank"〉PubMed〈/a〉

    A mutually assured destruction mechanism attenuates light signaling in Arabidopsis (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-06-07
    Description: After light-induced nuclear translocation, phytochrome photoreceptors interact with and induce rapid phosphorylation and degradation of basic helix-loop-helix transcription factors, such as PHYTOCHROME-INTERACTING FACTOR 3 (PIF3), to regulate gene expression. Concomitantly, this interaction triggers feedback reduction of phytochrome B (phyB) levels. Light-induced phosphorylation of PIF3 is necessary for the degradation of both proteins. We report that this PIF3 phosphorylation induces, and is necessary for, recruitment of LRB [Light-Response Bric-a-Brack/Tramtrack/Broad (BTB)] E3 ubiquitin ligases to the PIF3-phyB complex. The recruited LRBs promote concurrent polyubiqutination and degradation of both PIF3 and phyB in vivo.

    Description: Retinoblastoma is a childhood retinal tumour that initiates in response to biallelic RB1 inactivation and loss of functional retinoblastoma (Rb) protein. Although Rb has diverse tumour-suppressor functions and is inactivated in many cancers, germline RB1 mutations predispose to retinoblastoma far more strongly than to other malignancies. This tropism suggests that retinal cell-type-specific circuitry sensitizes to Rb loss, yet the nature of the circuitry and the cell type in which it operates have been unclear. Here we show that post-mitotic human cone precursors are uniquely sensitive to Rb depletion. Rb knockdown induced cone precursor proliferation in prospectively isolated populations and in intact retina. Proliferation followed the induction of E2F-regulated genes, and depended on factors having strong expression in maturing cone precursors and crucial roles in retinoblastoma cell proliferation, including MYCN and MDM2. Proliferation of Rb-depleted cones and retinoblastoma cells also depended on the Rb-related protein p107, SKP2, and a p27 downregulation associated with cone precursor maturation. Moreover, Rb-depleted cone precursors formed tumours in orthotopic xenografts with histological features and protein expression typical of human retinoblastoma. These findings provide a compelling molecular rationale for a cone precursor origin of retinoblastoma. More generally, they demonstrate that cell-type-specific circuitry can collaborate with an initiating oncogenic mutation to enable tumorigenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4232224/" 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/PMC4232224/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Xiaoliang L -- Singh, Hardeep P -- Wang, Lu -- Qi, Dong-Lai -- Poulos, Bradford K -- Abramson, David H -- Jhanwar, Suresh C -- Cobrinik, David -- 1R01CA137124/CA/NCI NIH HHS/ -- R01 CA137124/CA/NCI NIH HHS/ -- England -- Nature. 2014 Oct 16;514(7522):385-8. doi: 10.1038/nature13813.
