    Structural and molecular interrogation of intact biological systems (2013)
    Nature Publishing Group (NPG)

    Publication Date: 2013-04-12
    Description: Obtaining high-resolution information from a complex system, while maintaining the global perspective needed to understand system function, represents a key challenge in biology. Here we address this challenge with a method (termed CLARITY) for the transformation of intact tissue into a nanoporous hydrogel-hybridized form (crosslinked to a three-dimensional network of hydrophilic polymers) that is fully assembled but optically transparent and macromolecule-permeable. Using mouse brains, we show intact-tissue imaging of long-range projections, local circuit wiring, cellular relationships, subcellular structures, protein complexes, nucleic acids and neurotransmitters. CLARITY also enables intact-tissue in situ hybridization, immunohistochemistry with multiple rounds of staining and de-staining in non-sectioned tissue, and antibody labelling throughout the intact adult mouse brain. Finally, we show that CLARITY enables fine structural analysis of clinical samples, including non-sectioned human tissue from a neuropsychiatric-disease setting, establishing a path for the transmutation of human tissue into a stable, intact and accessible form suitable for probing structural and molecular underpinnings of physiological function and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4092167/" 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/PMC4092167/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chung, Kwanghun -- Wallace, Jenelle -- Kim, Sung-Yon -- Kalyanasundaram, Sandhiya -- Andalman, Aaron S -- Davidson, Thomas J -- Mirzabekov, Julie J -- Zalocusky, Kelly A -- Mattis, Joanna -- Denisin, Aleksandra K -- Pak, Sally -- Bernstein, Hannah -- Ramakrishnan, Charu -- Grosenick, Logan -- Gradinaru, Viviana -- Deisseroth, Karl -- DP1 OD000616/OD/NIH HHS/ -- R01 DA020794/DA/NIDA NIH HHS/ -- R01 MH099647/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 May 16;497(7449):332-7. doi: 10.1038/nature12107.

    Alveolar progenitor and stem cells in lung development, renewal and cancer (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-02-07
    Description: Alveoli are gas-exchange sacs lined by squamous alveolar type (AT) 1 cells and cuboidal, surfactant-secreting AT2 cells. Classical studies suggested that AT1 arise from AT2 cells, but recent studies propose other sources. Here we use molecular markers, lineage tracing and clonal analysis to map alveolar progenitors throughout the mouse lifespan. We show that, during development, AT1 and AT2 cells arise directly from a bipotent progenitor, whereas after birth new AT1 cells derive from rare, self-renewing, long-lived, mature AT2 cells that produce slowly expanding clonal foci of alveolar renewal. This stem-cell function is broadly activated by AT1 injury, and AT2 self-renewal is selectively induced by EGFR (epidermal growth factor receptor) ligands in vitro and oncogenic Kras(G12D) in vivo, efficiently generating multifocal, clonal adenomas. Thus, there is a switch after birth, when AT2 cells function as stem cells that contribute to alveolar renewal, repair and cancer. We propose that local signals regulate AT2 stem-cell activity: a signal transduced by EGFR-KRAS controls self-renewal and is hijacked during oncogenesis, whereas another signal controls reprogramming to AT1 fate.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4013278/" 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/PMC4013278/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Desai, Tushar J -- Brownfield, Douglas G -- Krasnow, Mark A -- P30 CA124435/CA/NCI NIH HHS/ -- U01 HL099995/HL/NHLBI NIH HHS/ -- U01 HL099999/HL/NHLBI NIH HHS/ -- England -- Nature. 2014 Mar 13;507(7491):190-4. doi: 10.1038/nature12930.

    Pre-Columbian mycobacterial genomes reveal seals as a source of New World human tuberculosis (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-08-21
    Description: Modern strains of Mycobacterium tuberculosis from the Americas are closely related to those from Europe, supporting the assumption that human tuberculosis was introduced post-contact. This notion, however, is incompatible with archaeological evidence of pre-contact tuberculosis in the New World. Comparative genomics of modern isolates suggests that M. tuberculosis attained its worldwide distribution following human dispersals out of Africa during the Pleistocene epoch, although this has yet to be confirmed with ancient calibration points. Here we present three 1,000-year-old mycobacterial genomes from Peruvian human skeletons, revealing that a member of the M. tuberculosis complex caused human disease before contact. The ancient strains are distinct from known human-adapted forms and are most closely related to those adapted to seals and sea lions. Two independent dating approaches suggest a most recent common ancestor for the M. tuberculosis complex less than 6,000 years ago, which supports a Holocene dispersal of the disease. Our results implicate sea mammals as having played a role in transmitting the disease to humans across the ocean.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4550673/" 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/PMC4550673/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bos, Kirsten I -- Harkins, Kelly M -- Herbig, Alexander -- Coscolla, Mireia -- Weber, Nico -- Comas, Inaki -- Forrest, Stephen A -- Bryant, Josephine M -- Harris, Simon R -- Schuenemann, Verena J -- Campbell, Tessa J -- Majander, Kerttu -- Wilbur, Alicia K -- Guichon, Ricardo A -- Wolfe Steadman, Dawnie L -- Cook, Della Collins -- Niemann, Stefan -- Behr, Marcel A -- Zumarraga, Martin -- Bastida, Ricardo -- Huson, Daniel -- Nieselt, Kay -- Young, Douglas -- Parkhill, Julian -- Buikstra, Jane E -- Gagneux, Sebastien -- Stone, Anne C -- Krause, Johannes -- 098051/Wellcome Trust/United Kingdom -- AI090928/AI/NIAID NIH HHS/ -- MC_U117581288/Medical Research Council/United Kingdom -- R01 AI090928/AI/NIAID NIH HHS/ -- Medical Research Council/United Kingdom -- England -- Nature. 2014 Oct 23;514(7523):494-7. doi: 10.1038/nature13591.

    Radial glia require PDGFD-PDGFRbeta signalling in human but not mouse neocortex (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-11-14
    Description: Evolutionary expansion of the human neocortex underlies many of our unique mental abilities. This expansion has been attributed to the increased proliferative potential of radial glia (RG; neural stem cells) and their subventricular dispersion from the periventricular niche during neocortical development. Such adaptations may have evolved through gene expression changes in RG. However, whether or how RG gene expression varies between humans and other species is unknown. Here we show that the transcriptional profiles of human and mouse neocortical RG are broadly conserved during neurogenesis, yet diverge for specific signalling pathways. By analysing differential gene co-expression relationships between the species, we demonstrate that the growth factor PDGFD is specifically expressed by RG in human, but not mouse, corticogenesis. We also show that the expression domain of PDGFRbeta, the cognate receptor for PDGFD, is evolutionarily divergent, with high expression in the germinal region of dorsal human neocortex but not in the mouse. Pharmacological inhibition of PDGFD-PDGFRbeta signalling in slice culture prevents normal cell cycle progression of neocortical RG in human, but not mouse. Conversely, injection of recombinant PDGFD or ectopic expression of constitutively active PDGFRbeta in developing mouse neocortex increases the proportion of RG and their subventricular dispersion. These findings highlight the requirement of PDGFD-PDGFRbeta signalling for human neocortical development and suggest that local production of growth factors by RG supports the expanded germinal region and progenitor heterogeneity of species with large brains.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4231536/" 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/PMC4231536/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lui, Jan H -- Nowakowski, Tomasz J -- Pollen, Alex A -- Javaherian, Ashkan -- Kriegstein, Arnold R -- Oldham, Michael C -- R01 NS021223/NS/NINDS NIH HHS/ -- R01 NS072630/NS/NINDS NIH HHS/ -- R01 NS075998/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Nov 13;515(7526):264-8. doi: 10.1038/nature13973.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology and The Eli and Edythe Broad Center of Regeneration Medicine and Stem Cell Research, University of California, San Francisco, San Francisco, California 94143, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25391964" target="_blank"〉PubMed〈/a〉

    A relative shift in cloacal location repositions external genitalia in amniote evolution (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-11-11
    Description: The move of vertebrates to a terrestrial lifestyle required major adaptations in their locomotory apparatus and reproductive organs. While the fin-to-limb transition has received considerable attention, little is known about the developmental and evolutionary origins of external genitalia. Similarities in gene expression have been interpreted as a potential evolutionary link between the limb and genitals; however, no underlying developmental mechanism has been identified. We re-examined this question using micro-computed tomography, lineage tracing in three amniote clades, and RNA-sequencing-based transcriptional profiling. Here we show that the developmental origin of external genitalia has shifted through evolution, and in some taxa limbs and genitals share a common primordium. In squamates, the genitalia develop directly from the budding hindlimbs, or the remnants thereof, whereas in mice the genital tubercle originates from the ventral and tail bud mesenchyme. The recruitment of different cell populations for genital outgrowth follows a change in the relative position of the cloaca, the genitalia organizing centre. Ectopic grafting of the cloaca demonstrates the conserved ability of different mesenchymal cells to respond to these genitalia-inducing signals. Our results support a limb-like developmental origin of external genitalia as the ancestral condition. Moreover, they suggest that a change in the relative position of the cloacal signalling centre during evolution has led to an altered developmental route for external genitalia in mammals, while preserving parts of the ancestral limb molecular circuitry owing to a common evolutionary origin.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4294627/" 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/PMC4294627/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tschopp, Patrick -- Sherratt, Emma -- Sanger, Thomas J -- Groner, Anna C -- Aspiras, Ariel C -- Hu, Jimmy K -- Pourquie, Olivier -- Gros, Jerome -- Tabin, Clifford J -- R37 HD032443/HD/NICHD NIH HHS/ -- R37-HD032443/HD/NICHD NIH HHS/ -- England -- Nature. 2014 Dec 18;516(7531):391-4. doi: 10.1038/nature13819.

    Interferon-gamma links ultraviolet radiation to melanomagenesis in mice (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-01-21
    Description: Cutaneous malignant melanoma is a highly aggressive and frequently chemoresistant cancer, the incidence of which continues to rise. Epidemiological studies show that the major aetiological melanoma risk factor is ultraviolet (UV) solar radiation, with the highest risk associated with intermittent burning doses, especially during childhood. We have experimentally validated these epidemiological findings using the hepatocyte growth factor/scatter factor transgenic mouse model, which develops lesions in stages highly reminiscent of human melanoma with respect to biological, genetic and aetiological criteria, but only when irradiated as neonatal pups with UVB, not UVA. However, the mechanisms underlying UVB-initiated, neonatal-specific melanomagenesis remain largely unknown. Here we introduce a mouse model permitting fluorescence-aided melanocyte imaging and isolation following in vivo UV irradiation. We use expression profiling to show that activated neonatal skin melanocytes isolated following a melanomagenic UVB dose bear a distinct, persistent interferon response signature, including genes associated with immunoevasion. UVB-induced melanocyte activation, characterized by aberrant growth and migration, was abolished by antibody-mediated systemic blockade of interferon-gamma (IFN-gamma), but not type-I interferons. IFN-gamma was produced by macrophages recruited to neonatal skin by UVB-induced ligands to the chemokine receptor Ccr2. Admixed recruited skin macrophages enhanced transplanted melanoma growth by inhibiting apoptosis; notably, IFN-gamma blockade abolished macrophage-enhanced melanoma growth and survival. IFN-gamma-producing macrophages were also identified in 70% of human melanomas examined. Our data reveal an unanticipated role for IFN-gamma in promoting melanocytic cell survival/immunoevasion, identifying a novel candidate therapeutic target for a subset of melanoma patients.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3140101/" 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/PMC3140101/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zaidi, M Raza -- Davis, Sean -- Noonan, Frances P -- Graff-Cherry, Cari -- Hawley, Teresa S -- Walker, Robert L -- Feigenbaum, Lionel -- Fuchs, Elaine -- Lyakh, Lyudmila -- Young, Howard A -- Hornyak, Thomas J -- Arnheiter, Heinz -- Trinchieri, Giorgio -- Meltzer, Paul S -- De Fabo, Edward C -- Merlino, Glenn -- CA53765/CA/NCI NIH HHS/ -- CA92258/CA/NCI NIH HHS/ -- R01 CA053765-10S1/CA/NCI NIH HHS/ -- R01 CA092258-05/CA/NCI NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2011 Jan 27;469(7331):548-53. doi: 10.1038/nature09666.

    The histone methyltransferase SETDB1 is recurrently amplified in melanoma and accelerates its onset (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-03-25
    Description: The most common mutation in human melanoma, BRAF(V600E), activates the serine/threonine kinase BRAF and causes excessive activity in the mitogen-activated protein kinase pathway. BRAF(V600E) mutations are also present in benign melanocytic naevi, highlighting the importance of additional genetic alterations in the genesis of malignant tumours. Such changes include recurrent copy number variations that result in the amplification of oncogenes. For certain amplifications, the large number of genes in the interval has precluded an understanding of the cooperating oncogenic events. Here we have used a zebrafish melanoma model to test genes in a recurrently amplified region of chromosome 1 for the ability to cooperate with BRAF(V600E) and accelerate melanoma. SETDB1, an enzyme that methylates histone H3 on lysine 9 (H3K9), was found to accelerate melanoma formation significantly in zebrafish. Chromatin immunoprecipitation coupled with massively parallel DNA sequencing and gene expression analyses uncovered genes, including HOX genes, that are transcriptionally dysregulated in response to increased levels of SETDB1. Our studies establish SETDB1 as an oncogene in melanoma and underscore the role of chromatin factors in regulating tumorigenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3348545/" 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/PMC3348545/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ceol, Craig J -- Houvras, Yariv -- Jane-Valbuena, Judit -- Bilodeau, Steve -- Orlando, David A -- Battisti, Valentine -- Fritsch, Lauriane -- Lin, William M -- Hollmann, Travis J -- Ferre, Fabrizio -- Bourque, Caitlin -- Burke, Christopher J -- Turner, Laura -- Uong, Audrey -- Johnson, Laura A -- Beroukhim, Rameen -- Mermel, Craig H -- Loda, Massimo -- Ait-Si-Ali, Slimane -- Garraway, Levi A -- Young, Richard A -- Zon, Leonard I -- CA103846/CA/NCI NIH HHS/ -- CA146455/CA/NCI NIH HHS/ -- DK055381/DK/NIDDK NIH HHS/ -- HG002668/HG/NHGRI NIH HHS/ -- K08 DK075432/DK/NIDDK NIH HHS/ -- K08 DK075432-04/DK/NIDDK NIH HHS/ -- K08DK075432-04/DK/NIDDK NIH HHS/ -- K99AR056899-02/AR/NIAMS NIH HHS/ -- R00 AR056899/AR/NIAMS NIH HHS/ -- R00 AR056899-02/AR/NIAMS NIH HHS/ -- R01 CA103846/CA/NCI NIH HHS/ -- R01 CA103846-09/CA/NCI NIH HHS/ -- R01 CA146445/CA/NCI NIH HHS/ -- R01 CA146445-03/CA/NCI NIH HHS/ -- R01 HG002668/HG/NHGRI NIH HHS/ -- R01 HG002668-08/HG/NHGRI NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- Canadian Institutes of Health Research/Canada -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Mar 24;471(7339):513-7. doi: 10.1038/nature09806.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stem Cell Program and Hematology/Oncology, Children's Hospital Boston, Howard Hughes Medical Institute, Harvard Medical School, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21430779" target="_blank"〉PubMed〈/a〉

    Clonal selection drives genetic divergence of metastatic medulloblastoma (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-02-22
    Description: Medulloblastoma, the most common malignant paediatric brain tumour, arises in the cerebellum and disseminates through the cerebrospinal fluid in the leptomeningeal space to coat the brain and spinal cord. Dissemination, a marker of poor prognosis, is found in up to 40% of children at diagnosis and in most children at the time of recurrence. Affected children therefore are treated with radiation to the entire developing brain and spinal cord, followed by high-dose chemotherapy, with the ensuing deleterious effects on the developing nervous system. The mechanisms of dissemination through the cerebrospinal fluid are poorly studied, and medulloblastoma metastases have been assumed to be biologically similar to the primary tumour. Here we show that in both mouse and human medulloblastoma, the metastases from an individual are extremely similar to each other but are divergent from the matched primary tumour. Clonal genetic events in the metastases can be demonstrated in a restricted subclone of the primary tumour, suggesting that only rare cells within the primary tumour have the ability to metastasize. Failure to account for the bicompartmental nature of metastatic medulloblastoma could be a major barrier to the development of effective targeted therapies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3288636/" 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/PMC3288636/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Xiaochong -- Northcott, Paul A -- Dubuc, Adrian -- Dupuy, Adam J -- Shih, David J H -- Witt, Hendrik -- Croul, Sidney -- Bouffet, Eric -- Fults, Daniel W -- Eberhart, Charles G -- Garzia, Livia -- Van Meter, Timothy -- Zagzag, David -- Jabado, Nada -- Schwartzentruber, Jeremy -- Majewski, Jacek -- Scheetz, Todd E -- Pfister, Stefan M -- Korshunov, Andrey -- Li, Xiao-Nan -- Scherer, Stephen W -- Cho, Yoon-Jae -- Akagi, Keiko -- MacDonald, Tobey J -- Koster, Jan -- McCabe, Martin G -- Sarver, Aaron L -- Collins, V Peter -- Weiss, William A -- Largaespada, David A -- Collier, Lara S -- Taylor, Michael D -- K01CA122183/CA/NCI NIH HHS/ -- NS055089/NS/NINDS NIH HHS/ -- R01 CA108622/CA/NCI NIH HHS/ -- R01 CA113636/CA/NCI NIH HHS/ -- R01 CA148699/CA/NCI NIH HHS/ -- R01 CA148699-03/CA/NCI NIH HHS/ -- R01 NS055089/NS/NINDS NIH HHS/ -- R01CA148699/CA/NCI NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2012 Feb 15;482(7386):529-33. doi: 10.1038/nature10825.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Arthur and Sonia Labatt Brain Tumour Research Center, Program in Developmental and Stem Cell Biology, The Hospital for Sick Children, Toronto, Ontario M5G 1X8, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22343890" target="_blank"〉PubMed〈/a〉

    Pancreatic cancer genomes reveal aberrations in axon guidance pathway genes (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-10-30
    Description: Pancreatic cancer is a highly lethal malignancy with few effective therapies. We performed exome sequencing and copy number analysis to define genomic aberrations in a prospectively accrued clinical cohort (n = 142) of early (stage I and II) sporadic pancreatic ductal adenocarcinoma. Detailed analysis of 99 informative tumours identified substantial heterogeneity with 2,016 non-silent mutations and 1,628 copy-number variations. We define 16 significantly mutated genes, reaffirming known mutations (KRAS, TP53, CDKN2A, SMAD4, MLL3, TGFBR2, ARID1A and SF3B1), and uncover novel mutated genes including additional genes involved in chromatin modification (EPC1 and ARID2), DNA damage repair (ATM) and other mechanisms (ZIM2, MAP2K4, NALCN, SLC16A4 and MAGEA6). Integrative analysis with in vitro functional data and animal models provided supportive evidence for potential roles for these genetic aberrations in carcinogenesis. Pathway-based analysis of recurrently mutated genes recapitulated clustering in core signalling pathways in pancreatic ductal adenocarcinoma, and identified new mutated genes in each pathway. We also identified frequent and diverse somatic aberrations in genes described traditionally as embryonic regulators of axon guidance, particularly SLIT/ROBO signalling, which was also evident in murine Sleeping Beauty transposon-mediated somatic mutagenesis models of pancreatic cancer, providing further supportive evidence for the potential involvement of axon guidance genes in pancreatic carcinogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3530898/" 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/PMC3530898/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biankin, Andrew V -- Waddell, Nicola -- Kassahn, Karin S -- Gingras, Marie-Claude -- Muthuswamy, Lakshmi B -- Johns, Amber L -- Miller, David K -- Wilson, Peter J -- Patch, Ann-Marie -- Wu, Jianmin -- Chang, David K -- Cowley, Mark J -- Gardiner, Brooke B -- Song, Sarah -- Harliwong, Ivon -- Idrisoglu, Senel -- Nourse, Craig -- Nourbakhsh, Ehsan -- Manning, Suzanne -- Wani, Shivangi -- Gongora, Milena -- Pajic, Marina -- Scarlett, Christopher J -- Gill, Anthony J -- Pinho, Andreia V -- Rooman, Ilse -- Anderson, Matthew -- Holmes, Oliver -- Leonard, Conrad -- Taylor, Darrin -- Wood, Scott -- Xu, Qinying -- Nones, Katia -- Fink, J Lynn -- Christ, Angelika -- Bruxner, Tim -- Cloonan, Nicole -- Kolle, Gabriel -- Newell, Felicity -- Pinese, Mark -- Mead, R Scott -- Humphris, Jeremy L -- Kaplan, Warren -- Jones, Marc D -- Colvin, Emily K -- Nagrial, Adnan M -- Humphrey, Emily S -- Chou, Angela -- Chin, Venessa T -- Chantrill, Lorraine A -- Mawson, Amanda -- Samra, Jaswinder S -- Kench, James G -- Lovell, Jessica A -- Daly, Roger J -- Merrett, Neil D -- Toon, Christopher -- Epari, Krishna -- Nguyen, Nam Q -- Barbour, Andrew -- Zeps, Nikolajs -- Australian Pancreatic Cancer Genome Initiative -- Kakkar, Nipun -- Zhao, Fengmei -- Wu, Yuan Qing -- Wang, Min -- Muzny, Donna M -- Fisher, William E -- Brunicardi, F Charles -- Hodges, Sally E -- Reid, Jeffrey G -- Drummond, Jennifer -- Chang, Kyle -- Han, Yi -- Lewis, Lora R -- Dinh, Huyen -- Buhay, Christian J -- Beck, Timothy -- Timms, Lee -- Sam, Michelle -- Begley, Kimberly -- Brown, Andrew -- Pai, Deepa -- Panchal, Ami -- Buchner, Nicholas -- De Borja, Richard -- Denroche, Robert E -- Yung, Christina K -- Serra, Stefano -- Onetto, Nicole -- Mukhopadhyay, Debabrata -- Tsao, Ming-Sound -- Shaw, Patricia A -- Petersen, Gloria M -- Gallinger, Steven -- Hruban, Ralph H -- Maitra, Anirban -- Iacobuzio-Donahue, Christine A -- Schulick, Richard D -- Wolfgang, Christopher L -- Morgan, Richard A -- Lawlor, Rita T -- Capelli, Paola -- Corbo, Vincenzo -- Scardoni, Maria -- Tortora, Giampaolo -- Tempero, Margaret A -- Mann, Karen M -- Jenkins, Nancy A -- Perez-Mancera, Pedro A -- Adams, David J -- Largaespada, David A -- Wessels, Lodewyk F A -- Rust, Alistair G -- Stein, Lincoln D -- Tuveson, David A -- Copeland, Neal G -- Musgrove, Elizabeth A -- Scarpa, Aldo -- Eshleman, James R -- Hudson, Thomas J -- Sutherland, Robert L -- Wheeler, David A -- Pearson, John V -- McPherson, John D -- Gibbs, Richard A -- Grimmond, Sean M -- 13031/Cancer Research UK/United Kingdom -- 2P50CA101955/CA/NCI NIH HHS/ -- P01CA134292/CA/NCI NIH HHS/ -- P50 CA101955/CA/NCI NIH HHS/ -- P50 CA102701/CA/NCI NIH HHS/ -- P50CA062924/CA/NCI NIH HHS/ -- R01 CA097075/CA/NCI NIH HHS/ -- R01 CA97075/CA/NCI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Cancer Research UK/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2012 Nov 15;491(7424):399-405. doi: 10.1038/nature11547.

    Teneurins instruct synaptic partner matching in an olfactory map (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-03-20
    Description: Neurons are interconnected with extraordinary precision to assemble a functional nervous system. Compared to axon guidance, far less is understood about how individual pre- and postsynaptic partners are matched. To ensure the proper relay of olfactory information in the fruitfly Drosophila, axons of approximately 50 classes of olfactory receptor neurons (ORNs) form one-to-one connections with dendrites of approximately 50 classes of projection neurons (PNs). Here, using genetic screens, we identified two evolutionarily conserved, epidermal growth factor (EGF)-repeat containing transmembrane Teneurin proteins, Ten-m and Ten-a, as synaptic-partner-matching molecules between PN dendrites and ORN axons. Ten-m and Ten-a are highly expressed in select PN-ORN matching pairs. Teneurin loss- and gain-of-function cause specific mismatching of select ORNs and PNs. Finally, Teneurins promote homophilic interactions in vitro, and Ten-m co-expression in non-partner PNs and ORNs promotes their ectopic connections in vivo. We propose that Teneurins instruct matching specificity between synaptic partners through homophilic attraction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3345284/" 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/PMC3345284/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hong, Weizhe -- Mosca, Timothy J -- Luo, Liqun -- 5T32 NS007280/NS/NINDS NIH HHS/ -- HD007249/HD/NICHD NIH HHS/ -- R01 DC-005982/DC/NIDCD NIH HHS/ -- R01 DC005982/DC/NIDCD NIH HHS/ -- R01 DC005982-10/DC/NIDCD NIH HHS/ -- T32 HD007249/HD/NICHD NIH HHS/ -- T32 HD007249-28/HD/NICHD NIH HHS/ -- T32 NS007280/NS/NINDS NIH HHS/ -- T32 NS007280-25/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Mar 18;484(7393):201-7. doi: 10.1038/nature10926.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Howard Hughes Medical Institute, Stanford University, Stanford, California 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22425994" target="_blank"〉PubMed〈/a〉
