    Origins and functional impact of copy number variation in the human genome (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-10-09
    Description: Structural variations of DNA greater than 1 kilobase in size account for most bases that vary among human genomes, but are still relatively under-ascertained. Here we use tiling oligonucleotide microarrays, comprising 42 million probes, to generate a comprehensive map of 11,700 copy number variations (CNVs) greater than 443 base pairs, of which most (8,599) have been validated independently. For 4,978 of these CNVs, we generated reference genotypes from 450 individuals of European, African or East Asian ancestry. The predominant mutational mechanisms differ among CNV size classes. Retrotransposition has duplicated and inserted some coding and non-coding DNA segments randomly around the genome. Furthermore, by correlation with known trait-associated single nucleotide polymorphisms (SNPs), we identified 30 loci with CNVs that are candidates for influencing disease susceptibility. Despite this, having assessed the completeness of our map and the patterns of linkage disequilibrium between CNVs and SNPs, we conclude that, for complex traits, the heritability void left by genome-wide association studies will not be accounted for by common CNVs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3330748/" 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/PMC3330748/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Conrad, Donald F -- Pinto, Dalila -- Redon, Richard -- Feuk, Lars -- Gokcumen, Omer -- Zhang, Yujun -- Aerts, Jan -- Andrews, T Daniel -- Barnes, Chris -- Campbell, Peter -- Fitzgerald, Tomas -- Hu, Min -- Ihm, Chun Hwa -- Kristiansson, Kati -- Macarthur, Daniel G -- Macdonald, Jeffrey R -- Onyiah, Ifejinelo -- Pang, Andy Wing Chun -- Robson, Sam -- Stirrups, Kathy -- Valsesia, Armand -- Walter, Klaudia -- Wei, John -- Wellcome Trust Case Control Consortium -- Tyler-Smith, Chris -- Carter, Nigel P -- Lee, Charles -- Scherer, Stephen W -- Hurles, Matthew E -- 077006/Z/05/Z/Wellcome Trust/United Kingdom -- 077008/Wellcome Trust/United Kingdom -- 077009/Wellcome Trust/United Kingdom -- 077014/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- GM081533/GM/NIGMS NIH HHS/ -- HG004221/HG/NHGRI NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2010 Apr 1;464(7289):704-12. doi: 10.1038/nature08516.

    Topological domains in mammalian genomes identified by analysis of chromatin interactions (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-04-13
    Description: The spatial organization of the genome is intimately linked to its biological function, yet our understanding of higher order genomic structure is coarse, fragmented and incomplete. In the nucleus of eukaryotic cells, interphase chromosomes occupy distinct chromosome territories, and numerous models have been proposed for how chromosomes fold within chromosome territories. These models, however, provide only few mechanistic details about the relationship between higher order chromatin structure and genome function. Recent advances in genomic technologies have led to rapid advances in the study of three-dimensional genome organization. In particular, Hi-C has been introduced as a method for identifying higher order chromatin interactions genome wide. Here we investigate the three-dimensional organization of the human and mouse genomes in embryonic stem cells and terminally differentiated cell types at unprecedented resolution. We identify large, megabase-sized local chromatin interaction domains, which we term 'topological domains', as a pervasive structural feature of the genome organization. These domains correlate with regions of the genome that constrain the spread of heterochromatin. The domains are stable across different cell types and highly conserved across species, indicating that topological domains are an inherent property of mammalian genomes. Finally, we find that the boundaries of topological domains are enriched for the insulator binding protein CTCF, housekeeping genes, transfer RNAs and short interspersed element (SINE) retrotransposons, indicating that these factors may have a role in establishing the topological domain structure of the genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3356448/" 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/PMC3356448/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dixon, Jesse R -- Selvaraj, Siddarth -- Yue, Feng -- Kim, Audrey -- Li, Yan -- Shen, Yin -- Hu, Ming -- Liu, Jun S -- Ren, Bing -- R01 HG003991/HG/NHGRI NIH HHS/ -- R01 HG003991-03/HG/NHGRI NIH HHS/ -- R01 HG003991-03S1/HG/NHGRI NIH HHS/ -- R01GH003991/GH/CGH CDC HHS/ -- England -- Nature. 2012 Apr 11;485(7398):376-80. doi: 10.1038/nature11082.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ludwig Institute for Cancer Research, 9500 Gilman Drive, La Jolla, California 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22495300" target="_blank"〉PubMed〈/a〉

    Crystal structure of the human glucose transporter GLUT1 (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-05-23
    Description: The glucose transporter GLUT1 catalyses facilitative diffusion of glucose into erythrocytes and is responsible for glucose supply to the brain and other organs. Dysfunctional mutations may lead to GLUT1 deficiency syndrome, whereas overexpression of GLUT1 is a prognostic indicator for cancer. Despite decades of investigation, the structure of GLUT1 remains unknown. Here we report the crystal structure of human GLUT1 at 3.2 A resolution. The full-length protein, which has a canonical major facilitator superfamily fold, is captured in an inward-open conformation. This structure allows accurate mapping and potential mechanistic interpretation of disease-associated mutations in GLUT1. Structure-based analysis of these mutations provides an insight into the alternating access mechanism of GLUT1 and other members of the sugar porter subfamily. Structural comparison of the uniporter GLUT1 with its bacterial homologue XylE, a proton-coupled xylose symporter, allows examination of the transport mechanisms of both passive facilitators and active transporters.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deng, Dong -- Xu, Chao -- Sun, Pengcheng -- Wu, Jianping -- Yan, Chuangye -- Hu, Mingxu -- Yan, Nieng -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Jun 5;510(7503):121-5. doi: 10.1038/nature13306.

    Nanoparticle biointerfacing by platelet membrane cloaking (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-09-17
    Description: Development of functional nanoparticles can be encumbered by unanticipated material properties and biological events, which can affect nanoparticle effectiveness in complex, physiologically relevant systems. Despite the advances in bottom-up nanoengineering and surface chemistry, reductionist functionalization approaches remain inadequate in replicating the complex interfaces present in nature and cannot avoid exposure of foreign materials. Here we report on the preparation of polymeric nanoparticles enclosed in the plasma membrane of human platelets, which are a unique population of cellular fragments that adhere to a variety of disease-relevant substrates. The resulting nanoparticles possess a right-side-out unilamellar membrane coating functionalized with immunomodulatory and adhesion antigens associated with platelets. Compared to uncoated particles, the platelet membrane-cloaked nanoparticles have reduced cellular uptake by macrophage-like cells and lack particle-induced complement activation in autologous human plasma. The cloaked nanoparticles also display platelet-mimicking properties such as selective adhesion to damaged human and rodent vasculatures as well as enhanced binding to platelet-adhering pathogens. In an experimental rat model of coronary restenosis and a mouse model of systemic bacterial infection, docetaxel and vancomycin, respectively, show enhanced therapeutic efficacy when delivered by the platelet-mimetic nanoparticles. The multifaceted biointerfacing enabled by the platelet membrane cloaking method provides a new approach in developing functional nanoparticles for disease-targeted delivery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hu, Che-Ming J -- Fang, Ronnie H -- Wang, Kuei-Chun -- Luk, Brian T -- Thamphiwatana, Soracha -- Dehaini, Diana -- Nguyen, Phu -- Angsantikul, Pavimol -- Wen, Cindy H -- Kroll, Ashley V -- Carpenter, Cody -- Ramesh, Manikantan -- Qu, Vivian -- Patel, Sherrina H -- Zhu, Jie -- Shi, William -- Hofman, Florence M -- Chen, Thomas C -- Gao, Weiwei -- Zhang, Kang -- Chien, Shu -- Zhang, Liangfang -- R01DK095168/DK/NIDDK NIH HHS/ -- R01EY25090/EY/NEI NIH HHS/ -- R01HL108735/HL/NHLBI NIH HHS/ -- R25CA153915/CA/NCI NIH HHS/ -- England -- Nature. 2015 Oct 1;526(7571):118-21. doi: 10.1038/nature15373.
