    Beschreibung: Brazil has experienced an unprecedented epidemic of Zika virus (ZIKV), with ~30,000 cases reported to date. ZIKV was first detected in Brazil in May 2015, and cases of microcephaly potentially associated with ZIKV infection were identified in November 2015. We performed next-generation sequencing to generate seven Brazilian ZIKV genomes sampled from four self-limited cases, one blood donor, one fatal adult case, and one newborn with microcephaly and congenital malformations. Results of phylogenetic and molecular clock analyses show a single introduction of ZIKV into the Americas, which we estimated to have occurred between May and December 2013, more than 12 months before the detection of ZIKV in Brazil. The estimated date of origin coincides with an increase in air passengers to Brazil from ZIKV-endemic areas, as well as with reported outbreaks in the Pacific Islands. ZIKV genomes from Brazil are phylogenetically interspersed with those from other South American and Caribbean countries. Mapping mutations onto existing structural models revealed the context of viral amino acid changes present in the outbreak lineage; however, no shared amino acid changes were found among the three currently available virus genomes from microcephaly cases. Municipality-level incidence data indicate that reports of suspected microcephaly in Brazil best correlate with ZIKV incidence around week 17 of pregnancy, although this correlation does not demonstrate causation. Our genetic description and analysis of ZIKV isolates in Brazil provide a baseline for future studies of the evolution and molecular epidemiology of this emerging virus in the Americas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faria, Nuno Rodrigues -- Azevedo, Raimunda do Socorro da Silva -- Kraemer, Moritz U G -- Souza, Renato -- Cunha, Mariana Sequetin -- Hill, Sarah C -- Theze, Julien -- Bonsall, Michael B -- Bowden, Thomas A -- Rissanen, Ilona -- Rocco, Iray Maria -- Nogueira, Juliana Silva -- Maeda, Adriana Yurika -- Vasami, Fernanda Giseli da Silva -- Macedo, Fernando Luiz de Lima -- Suzuki, Akemi -- Rodrigues, Sueli Guerreiro -- Cruz, Ana Cecilia Ribeiro -- Nunes, Bruno Tardeli -- Medeiros, Daniele Barbosa de Almeida -- Rodrigues, Daniela Sueli Guerreiro -- Nunes Queiroz, Alice Louize -- da Silva, Eliana Vieira Pinto -- Henriques, Daniele Freitas -- Travassos da Rosa, Elisabeth Salbe -- de Oliveira, Consuelo Silva -- Martins, Livia Caricio -- Vasconcelos, Helena Baldez -- Casseb, Livia Medeiros Neves -- Simith, Darlene de Brito -- Messina, Jane P -- Abade, Leandro -- Lourenco, Jose -- Carlos Junior Alcantara, Luiz -- de Lima, Maricelia Maia -- Giovanetti, Marta -- Hay, Simon I -- de Oliveira, Rodrigo Santos -- Lemos, Poliana da Silva -- de Oliveira, Layanna Freitas -- de Lima, Clayton Pereira Silva -- da Silva, Sandro Patroca -- de Vasconcelos, Janaina Mota -- Franco, Luciano -- Cardoso, Jedson Ferreira -- Vianez-Junior, Joao Lidio da Silva Goncalves -- Mir, Daiana -- Bello, Gonzalo -- Delatorre, Edson -- Khan, Kamran -- Creatore, Marisa -- Coelho, Giovanini Evelim -- de Oliveira, Wanderson Kleber -- Tesh, Robert -- Pybus, Oliver G -- Nunes, Marcio R T -- Vasconcelos, Pedro F C -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 095066/Wellcome Trust/United Kingdom -- 102427/Wellcome Trust/United Kingdom -- MR/L009528/1/Medical Research Council/United Kingdom -- R24 AT 120942/AT/NCCIH NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):345-9. doi: 10.1126/science.aaf5036.

    Beschreibung: One of the factors postulated to drive the aging process is the accumulation of DNA damage. Here, we provide strong support for this hypothesis by describing studies of mice with a mutation in XPD, a gene encoding a DNA helicase that functions in both repair and transcription and that is mutated in the human disorder trichothiodystrophy (TTD). TTD mice were found to exhibit many symptoms of premature aging, including osteoporosis and kyphosis, osteosclerosis, early greying, cachexia, infertility, and reduced life-span. TTD mice carrying an additional mutation in XPA, which enhances the DNA repair defect, showed a greatly accelerated aging phenotype, which correlated with an increased cellular sensitivity to oxidative DNA damage. We hypothesize that aging in TTD mice is caused by unrepaired DNA damage that compromises transcription, leading to functional inactivation of critical genes and enhanced apoptosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉de Boer, Jan -- Andressoo, Jaan Olle -- de Wit, Jan -- Huijmans, Jan -- Beems, Rudolph B -- van Steeg, Harry -- Weeda, Geert -- van der Horst, Gijsbertus T J -- van Leeuwen, Wibeke -- Themmen, Axel P N -- Meradji, Morteza -- Hoeijmakers, Jan H J -- AG 17242-02/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2002 May 17;296(5571):1276-9.

    Beschreibung: Species interaction networks are shaped by abiotic and biotic factors. Here, as part of the Tara Oceans project, we studied the photic zone interactome using environmental factors and organismal abundance profiles and found that environmental factors are incomplete predictors of community structure. We found associations across plankton functional types and phylogenetic groups to be nonrandomly distributed on the network and driven by both local and global patterns. We identified interactions among grazers, primary producers, viruses, and (mainly parasitic) symbionts and validated network-generated hypotheses using microscopy to confirm symbiotic relationships. We have thus provided a resource to support further research on ocean food webs and integrating biological components into ocean models.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lima-Mendez, Gipsi -- Faust, Karoline -- Henry, Nicolas -- Decelle, Johan -- Colin, Sebastien -- Carcillo, Fabrizio -- Chaffron, Samuel -- Ignacio-Espinosa, J Cesar -- Roux, Simon -- Vincent, Flora -- Bittner, Lucie -- Darzi, Youssef -- Wang, Jun -- Audic, Stephane -- Berline, Leo -- Bontempi, Gianluca -- Cabello, Ana M -- Coppola, Laurent -- Cornejo-Castillo, Francisco M -- d'Ovidio, Francesco -- De Meester, Luc -- Ferrera, Isabel -- Garet-Delmas, Marie-Jose -- Guidi, Lionel -- Lara, Elena -- Pesant, Stephane -- Royo-Llonch, Marta -- Salazar, Guillem -- Sanchez, Pablo -- Sebastian, Marta -- Souffreau, Caroline -- Dimier, Celine -- Picheral, Marc -- Searson, Sarah -- Kandels-Lewis, Stefanie -- Tara Oceans coordinators -- Gorsky, Gabriel -- Not, Fabrice -- Ogata, Hiroyuki -- Speich, Sabrina -- Stemmann, Lars -- Weissenbach, Jean -- Wincker, Patrick -- Acinas, Silvia G -- Sunagawa, Shinichi -- Bork, Peer -- Sullivan, Matthew B -- Karsenti, Eric -- Bowler, Chris -- de Vargas, Colomban -- Raes, Jeroen -- New York, N.Y. -- Science. 2015 May 22;348(6237):1262073. doi: 10.1126/science.1262073.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, Rega Institute KU Leuven, Herestraat 49, 3000 Leuven, Belgium.

    Beschreibung: A unique assemblage of 28 hominin individuals, found in Sima de los Huesos in the Sierra de Atapuerca in Spain, has recently been dated to approximately 430,000 years ago. An interesting question is how these Middle Pleistocene hominins were related to those who lived in the Late Pleistocene epoch, in particular to Neanderthals in western Eurasia and to Denisovans, a sister group of Neanderthals so far known only from southern Siberia. While the Sima de los Huesos hominins share some derived morphological features with Neanderthals, the mitochondrial genome retrieved from one individual from Sima de los Huesos is more closely related to the mitochondrial DNA of Denisovans than to that of Neanderthals. However, since the mitochondrial DNA does not reveal the full picture of relationships among populations, we have investigated DNA preservation in several individuals found at Sima de los Huesos. Here we recover nuclear DNA sequences from two specimens, which show that the Sima de los Huesos hominins were related to Neanderthals rather than to Denisovans, indicating that the population divergence between Neanderthals and Denisovans predates 430,000 years ago. A mitochondrial DNA recovered from one of the specimens shares the previously described relationship to Denisovan mitochondrial DNAs, suggesting, among other possibilities, that the mitochondrial DNA gene pool of Neanderthals turned over later in their history.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, Matthias -- Arsuaga, Juan-Luis -- de Filippo, Cesare -- Nagel, Sarah -- Aximu-Petri, Ayinuer -- Nickel, Birgit -- Martinez, Ignacio -- Gracia, Ana -- Bermudez de Castro, Jose Maria -- Carbonell, Eudald -- Viola, Bence -- Kelso, Janet -- Prufer, Kay -- Paabo, Svante -- England -- Nature. 2016 Mar 24;531(7595):504-7. doi: 10.1038/nature17405.

    Beschreibung: Colorectal cancer remains a major unmet medical need, prompting large-scale genomics efforts in the field to identify molecular drivers for which targeted therapies might be developed. We previously reported the identification of recurrent translocations in R-spondin genes present in a subset of colorectal tumours. Here we show that targeting RSPO3 in PTPRK-RSPO3-fusion-positive human tumour xenografts inhibits tumour growth and promotes differentiation. Notably, genes expressed in the stem-cell compartment of the intestine were among those most sensitive to anti-RSPO3 treatment. This observation, combined with functional assays, suggests that a stem-cell compartment drives PTPRK-RSPO3 colorectal tumour growth and indicates that the therapeutic targeting of stem-cell properties within tumours may be a clinically relevant approach for the treatment of colorectal tumours.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Storm, Elaine E -- Durinck, Steffen -- de Sousa e Melo, Felipe -- Tremayne, Jarrod -- Kljavin, Noelyn -- Tan, Christine -- Ye, Xiaofen -- Chiu, Cecilia -- Pham, Thinh -- Hongo, Jo-Anne -- Bainbridge, Travis -- Firestein, Ron -- Blackwood, Elizabeth -- Metcalfe, Ciara -- Stawiski, Eric W -- Yauch, Robert L -- Wu, Yan -- de Sauvage, Frederic J -- England -- Nature. 2016 Jan 7;529(7584):97-100. doi: 10.1038/nature16466.

    Beschreibung: Error-free repair of DNA double-strand breaks (DSBs) is achieved by homologous recombination (HR), and BRCA1 is an important factor for this repair pathway. In the absence of BRCA1-mediated HR, the administration of PARP inhibitors induces synthetic lethality of tumour cells of patients with breast or ovarian cancers. Despite the benefit of this tailored therapy, drug resistance can occur by HR restoration. Genetic reversion of BRCA1-inactivating mutations can be the underlying mechanism of drug resistance, but this does not explain resistance in all cases. In particular, little is known about BRCA1-independent restoration of HR. Here we show that loss of REV7 (also known as MAD2L2) in mouse and human cell lines re-establishes CTIP-dependent end resection of DSBs in BRCA1-deficient cells, leading to HR restoration and PARP inhibitor resistance, which is reversed by ATM kinase inhibition. REV7 is recruited to DSBs in a manner dependent on the H2AX-MDC1-RNF8-RNF168-53BP1 chromatin pathway, and seems to block HR and promote end joining in addition to its regulatory role in DNA damage tolerance. Finally, we establish that REV7 blocks DSB resection to promote non-homologous end-joining during immunoglobulin class switch recombination. Our results reveal an unexpected crucial function of REV7 downstream of 53BP1 in coordinating pathological DSB repair pathway choices in BRCA1-deficient cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4671316/" 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/PMC4671316/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Guotai -- Chapman, J Ross -- Brandsma, Inger -- Yuan, Jingsong -- Mistrik, Martin -- Bouwman, Peter -- Bartkova, Jirina -- Gogola, Ewa -- Warmerdam, Daniel -- Barazas, Marco -- Jaspers, Janneke E -- Watanabe, Kenji -- Pieterse, Mark -- Kersbergen, Ariena -- Sol, Wendy -- Celie, Patrick H N -- Schouten, Philip C -- van den Broek, Bram -- Salman, Ahmed -- Nieuwland, Marja -- de Rink, Iris -- de Ronde, Jorma -- Jalink, Kees -- Boulton, Simon J -- Chen, Junjie -- van Gent, Dik C -- Bartek, Jiri -- Jonkers, Jos -- Borst, Piet -- Rottenberg, Sven -- 090532/Wellcome Trust/United Kingdom -- 104558/Wellcome Trust/United Kingdom -- P30 CA016672/CA/NCI NIH HHS/ -- Cancer Research UK/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2015 May 28;521(7553):541-4. doi: 10.1038/nature14328.
