    Mutations in dynein link motor neuron degeneration to defects in retrograde transport (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-05-06
    Description: Degenerative disorders of motor neurons include a range of progressive fatal diseases such as amyotrophic lateral sclerosis (ALS), spinal-bulbar muscular atrophy (SBMA), and spinal muscular atrophy (SMA). Although the causative genetic alterations are known for some cases, the molecular basis of many SMA and SBMA-like syndromes and most ALS cases is unknown. Here we show that missense point mutations in the cytoplasmic dynein heavy chain result in progressive motor neuron degeneration in heterozygous mice, and in homozygotes this is accompanied by the formation of Lewy-like inclusion bodies, thus resembling key features of human pathology. These mutations exclusively perturb neuron-specific functions of dynein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hafezparast, Majid -- Klocke, Rainer -- Ruhrberg, Christiana -- Marquardt, Andreas -- Ahmad-Annuar, Azlina -- Bowen, Samantha -- Lalli, Giovanna -- Witherden, Abi S -- Hummerich, Holger -- Nicholson, Sharon -- Morgan, P Jeffrey -- Oozageer, Ravi -- Priestley, John V -- Averill, Sharon -- King, Von R -- Ball, Simon -- Peters, Jo -- Toda, Takashi -- Yamamoto, Ayumu -- Hiraoka, Yasushi -- Augustin, Martin -- Korthaus, Dirk -- Wattler, Sigrid -- Wabnitz, Philipp -- Dickneite, Carmen -- Lampel, Stefan -- Boehme, Florian -- Peraus, Gisela -- Popp, Andreas -- Rudelius, Martina -- Schlegel, Juergen -- Fuchs, Helmut -- Hrabe de Angelis, Martin -- Schiavo, Giampietro -- Shima, David T -- Russ, Andreas P -- Stumm, Gabriele -- Martin, Joanne E -- Fisher, Elizabeth M C -- New York, N.Y. -- Science. 2003 May 2;300(5620):808-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurodegenerative Disease, Institute of Neurology, National Hospital for Neurology and Neurosurgery, Queen Square, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12730604" target="_blank"〉PubMed〈/a〉

    Balancing selection at the prion protein gene consistent with prehistoric kurulike epidemics (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-04-12
    Description: Kuru is an acquired prion disease largely restricted to the Fore linguistic group of the Papua New Guinea Highlands, which was transmitted during endocannibalistic feasts. Heterozygosity for a common polymorphism in the human prion protein gene (PRNP) confers relative resistance to prion diseases. Elderly survivors of the kuru epidemic, who had multiple exposures at mortuary feasts, are, in marked contrast to younger unexposed Fore, predominantly PRNP 129 heterozygotes. Kuru imposed strong balancing selection on the Fore, essentially eliminating PRNP 129 homozygotes. Worldwide PRNP haplotype diversity and coding allele frequencies suggest that strong balancing selection at this locus occurred during the evolution of modern humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mead, Simon -- Stumpf, Michael P H -- Whitfield, Jerome -- Beck, Jonathan A -- Poulter, Mark -- Campbell, Tracy -- Uphill, James B -- Goldstein, David -- Alpers, Michael -- Fisher, Elizabeth M C -- Collinge, John -- New York, N.Y. -- Science. 2003 Apr 25;300(5619):640-3.

    An aneuploid mouse strain carrying human chromosome 21 with Down syndrome phenotypes (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-09-24
    Description: Aneuploidies are common chromosomal defects that result in growth and developmental deficits and high levels of lethality in humans. To gain insight into the biology of aneuploidies, we manipulated mouse embryonic stem cells and generated a trans-species aneuploid mouse line that stably transmits a freely segregating, almost complete human chromosome 21 (Hsa21). This "transchromosomic" mouse line, Tc1, is a model of trisomy 21, which manifests as Down syndrome (DS) in humans, and has phenotypic alterations in behavior, synaptic plasticity, cerebellar neuronal number, heart development, and mandible size that relate to human DS. Transchromosomic mouse lines such as Tc1 may represent useful genetic tools for dissecting other human aneuploidies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1378183/" 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/PMC1378183/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Doherty, Aideen -- Ruf, Sandra -- Mulligan, Claire -- Hildreth, Victoria -- Errington, Mick L -- Cooke, Sam -- Sesay, Abdul -- Modino, Sonie -- Vanes, Lesley -- Hernandez, Diana -- Linehan, Jacqueline M -- Sharpe, Paul T -- Brandner, Sebastian -- Bliss, Timothy V P -- Henderson, Deborah J -- Nizetic, Dean -- Tybulewicz, Victor L J -- Fisher, Elizabeth M C -- 076700/Wellcome Trust/United Kingdom -- MC_U117512674/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2005 Sep 23;309(5743):2033-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurodegenerative Disease, Institute of Neurology, Queen Square, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16179473" target="_blank"〉PubMed〈/a〉

    Tumour angiogenesis is reduced in the Tc1 mouse model of Down's syndrome (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-06-11
    Description: Down's syndrome (DS) is a genetic disorder caused by full or partial trisomy of human chromosome 21 and presents with many clinical phenotypes including a reduced incidence of solid tumours. Recent work with the Ts65Dn model of DS, which has orthologues of about 50% of the genes on chromosome 21 (Hsa21), has indicated that three copies of the ETS2 (ref. 3) or DS candidate region 1 (DSCR1) genes (a previously known suppressor of angiogenesis) is sufficient to inhibit tumour growth. Here we use the Tc1 transchromosomic mouse model of DS to dissect the contribution of extra copies of genes on Hsa21 to tumour angiogenesis. This mouse expresses roughly 81% of Hsa21 genes but not the human DSCR1 region. We transplanted B16F0 and Lewis lung carcinoma tumour cells into Tc1 mice and showed that growth of these tumours was substantially reduced compared with wild-type littermate controls. Furthermore, tumour angiogenesis was significantly repressed in Tc1 mice. In particular, in vitro and in vivo angiogenic responses to vascular endothelial growth factor (VEGF) were inhibited. Examination of the genes on the segment of Hsa21 in Tc1 mice identified putative anti-angiogenic genes (ADAMTS1and ERG) and novel endothelial cell-specific genes, never previously shown to be involved in angiogenesis (JAM-B and PTTG1IP), that, when overexpressed, are responsible for inhibiting angiogenic responses to VEGF. Three copies of these genes within the stromal compartment reduced tumour angiogenesis, explaining the reduced tumour growth in DS. Furthermore, we expect that, in addition to the candidate genes that we show to be involved in the repression of angiogenesis, the Tc1 mouse model of DS will permit the identification of other endothelium-specific anti-angiogenic targets relevant to a broad spectrum of cancer patients.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3479956/" 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/PMC3479956/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reynolds, Louise E -- Watson, Alan R -- Baker, Marianne -- Jones, Tania A -- D'Amico, Gabriela -- Robinson, Stephen D -- Joffre, Carine -- Garrido-Urbani, Sarah -- Rodriguez-Manzaneque, Juan Carlos -- Martino-Echarri, Estefania -- Aurrand-Lions, Michel -- Sheer, Denise -- Dagna-Bricarelli, Franca -- Nizetic, Dean -- McCabe, Christopher J -- Turnell, Andrew S -- Kermorgant, Stephanie -- Imhof, Beat A -- Adams, Ralf -- Fisher, Elizabeth M C -- Tybulewicz, Victor L J -- Hart, Ian R -- Hodivala-Dilke, Kairbaan M -- 080174/Wellcome Trust/United Kingdom -- 12007/Cancer Research UK/United Kingdom -- A12007/Cancer Research UK/United Kingdom -- A3585/Cancer Research UK/United Kingdom -- G0501003/Medical Research Council/United Kingdom -- G0501003(75694)/Medical Research Council/United Kingdom -- G0601056/Medical Research Council/United Kingdom -- G0901609/Medical Research Council/United Kingdom -- MC_U117527252/Medical Research Council/United Kingdom -- U.1175.02.001.00001(60485)/Medical Research Council/United Kingdom -- England -- Nature. 2010 Jun 10;465(7299):813-7. doi: 10.1038/nature09106.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Adhesion and Angiogenesis Laboratory, Barts Institute of Cancer, Barts and The London School of Medicine and Dentistry, Queen Mary University of London, John Vane Science Centre, Charterhouse Square, London EC1M 6BQ, UK. l.reynolds@qmul.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20535211" target="_blank"〉PubMed〈/a〉

    Species-specific transcription in mice carrying human chromosome 21 (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-09-13
    Description: Homologous sets of transcription factors direct conserved tissue-specific gene expression, yet transcription factor-binding events diverge rapidly between closely related species. We used hepatocytes from an aneuploid mouse strain carrying human chromosome 21 to determine, on a chromosomal scale, whether interspecies differences in transcriptional regulation are primarily directed by human genetic sequence or mouse nuclear environment. Virtually all transcription factor-binding locations, landmarks of transcription initiation, and the resulting gene expression observed in human hepatocytes were recapitulated across the entire human chromosome 21 in the mouse hepatocyte nucleus. Thus, in homologous tissues, genetic sequence is largely responsible for directing transcriptional programs; interspecies differences in epigenetic machinery, cellular environment, and transcription factors themselves play secondary roles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3717767/" 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/PMC3717767/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, Michael D -- Barbosa-Morais, Nuno L -- Schmidt, Dominic -- Conboy, Caitlin M -- Vanes, Lesley -- Tybulewicz, Victor L J -- Fisher, Elizabeth M C -- Tavare, Simon -- Odom, Duncan T -- 080174/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- G0601056/Medical Research Council/United Kingdom -- MC_U117527252/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Oct 17;322(5900):434-8. doi: 10.1126/science.1160930.

    C9orf72 repeat expansions cause neurodegeneration in Drosophila through arginine-rich proteins (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-08-12
    Description: An expanded GGGGCC repeat in C9orf72 is the most common genetic cause of frontotemporal dementia and amyotrophic lateral sclerosis. A fundamental question is whether toxicity is driven by the repeat RNA itself and/or by dipeptide repeat proteins generated by repeat-associated, non-ATG translation. To address this question, we developed in vitro and in vivo models to dissect repeat RNA and dipeptide repeat protein toxicity. Expression of pure repeats, but not stop codon-interrupted "RNA-only" repeats in Drosophila caused adult-onset neurodegeneration. Thus, expanded repeats promoted neurodegeneration through dipeptide repeat proteins. Expression of individual dipeptide repeat proteins with a non-GGGGCC RNA sequence revealed that both poly-(glycine-arginine) and poly-(proline-arginine) proteins caused neurodegeneration. These findings are consistent with a dual toxicity mechanism, whereby both arginine-rich proteins and repeat RNA contribute to C9orf72-mediated neurodegeneration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mizielinska, Sarah -- Gronke, Sebastian -- Niccoli, Teresa -- Ridler, Charlotte E -- Clayton, Emma L -- Devoy, Anny -- Moens, Thomas -- Norona, Frances E -- Woollacott, Ione O C -- Pietrzyk, Julian -- Cleverley, Karen -- Nicoll, Andrew J -- Pickering-Brown, Stuart -- Dols, Jacqueline -- Cabecinha, Melissa -- Hendrich, Oliver -- Fratta, Pietro -- Fisher, Elizabeth M C -- Partridge, Linda -- Isaacs, Adrian M -- 089701/Wellcome Trust/United Kingdom -- 098565/Wellcome Trust/United Kingdom -- G0701441/Medical Research Council/United Kingdom -- G1000287/Medical Research Council/United Kingdom -- MR/J004022/1/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Sep 5;345(6201):1192-4. doi: 10.1126/science.1256800.

    Notes: Abstract Trisomy 21 is the most common aneuploidy in humans with a frequency of 1 in 700 live births and is by far the most common defined cause of mental retardation. To analyse which of the chromosome 21 genes is overexpressed early in development – giving rise to the Down syndrome phenotype – and to provide candidate genes for other HSA21 disease loci, we need a transcription map of the chromosome. Therefore, to enrich the gene map of human chromosome 21 we have undertaken a systematic approach to fine mapping and characterising expressed sequences generated by the various cDNA sequencing projects. In this report we show the localisation of the CAF1P60 gene to human chromosome 21 and its fine mapping to 21q22.2 between D21S333 and D21S334. This mapping position places CAF1P60 in a region of HSA21 which is strongly associated with the major features of Down syndrome. The function of this gene product may have important implications for the phenotype that arises from trisomy 21.

    Notes: Abstract We have isolated a highly polymorphic sequence from the Down syndrome critical region on human chromosome 21. This is a particularly useful marker because it lies adjacent to the locus D21S55, which is most closely associated with the major defects on Down syndrome. Other than this marker, few other variable sequences are known in this region (including other restriction fragment length polymorphisms or CA repeats) and therefore D21S1448 will be extremely helpful not only for people studying the inheritance of portions of chromosome 21 with respect to Down syndrome, but also for those carrying out linkage analysis of the chromosome.

    Notes: Abstract To understand the architecture of the human genome, we need a complete definition of all the repeat sequence families, as these make up the majority of human DNA. We have isolated a small DNA fragment from human chromosome 21 and have used sequence analysis of this fragment to uncover a new low copy repeat element of approximately 300 bp that we term the Mermaid repeat. This repeat is related to, but is different from, the MER 12 repeat and is interspersed in the genome. Mermaid family members that we have studied are between 81%–87% identical to our preliminary consensus sequence. Therefore, we have added a new member to the large collection of human repetitive elements. In addition, we have mapped a Mermaid repeat to a telomeric position on the long arm of human chromosome 21, at 21q22.3

    Notes: Abstract The eukaryotic genome contains a putative ATPase gene family that encodes proteins with one or two highly conserved domain(s) of approximately 230 amino acids. These proteins have diverse cellular functions and mutation in at least one member of the family has been associated with human disease, while mutations in other family members are known to cause cell cycle defects in yeast. Therefore it is of interest to map more family members and so we have localized PSMC5 (the thyroid hormone receptor-interacting protein, TRIP1) and PSMC3 (the Tat-binding protein, TBP1) to chromosomes 17q24– q25 and 11p12–p13, respectively. We also present the map position of a probable PSMC3 processed pseudogene locus on chromosome 9p.
