    Description: We examined the influence of the tetratricopeptide repeat factor XAB2 on chromosomal break repair, and found that XAB2 promotes end resection that generates the 3' ssDNA intermediate for homologous recombination (HR). Namely, XAB2 is important for chromosomal double-strand break (DSB) repair via two pathways of HR that require end resection as an intermediate step, end resection of camptothecin (Cpt)-induced DNA damage, and RAD51 recruitment to ionizing radiation induced foci (IRIF), which requires end resection. Furthermore, XAB2 mediates specific aspects of the DNA damage response associated with end resection proficiency: CtIP hyperphosphorylation induced by Cpt and BRCA1 IRIF. XAB2 also promotes histone acetylation events linked to HR proficiency. From truncation mutation analysis, the capacity for XAB2 to promote HR correlates with its ability to form a complex with ISY1 and PRP19, which show a similar influence as XAB2 on HR. This XAB2 complex localizes to punctate structures consistent with interchromatin granules that show a striking adjacent-localization to the DSB marker H2AX. In summary, we suggest that the XAB2 complex mediates DNA damage response events important for the end resection step of HR, and speculate that its adjacent-localization relative to DSBs marked by H2AX is important for this function.

    Description: The mechanism of IFN-β therapy in relapsing-remitting multiple sclerosis (RRMS) is not well understood, but induction of apoptosis in specific leukocyte subsets is likely to be important. Enhanced expression of TNFSF10 or TNF-related apoptosis-inducing ligand (TRAIL) mRNA in unseparated leukocytes has been put forward as a therapeutic response marker, but it is unclear which leukocyte subsets express TRAIL. We investigated the basis of TRAIL expression in response to IFN-β by studying activation of STATs 1, 3, and 5, p38 MAPK, and NF-κB in different leukocyte subsets of patients with RRMS. Monocytes, B cells, and T cells showed substantial differences in the activation of p38 and the STATs in response to i.m. injection of IFN-β1a or stimulation in vitro. Induction of cell-surface TRAIL, analyzed in nine leukocyte subsets, was observed only on monocytes and granulocytes and correlated with the activation of p38 and/or NF-κB in these subsets only, in agreement with previous work in fibroblasts showing that the induction of TRAIL in response to IFN-β depends on the activation of p38 and NF-κB as well as STATs 1 and 2. We propose that, in myeloid cells, the differential activation of p38 and NF-κB and induction of TRAIL, which sensitizes cells to apoptosis, can help to explain differences in responsiveness to IFN-β therapy among patients with RRMS and, furthermore, that such differential patterns of activation and expression may also be important in understanding the therapeutic responses to IFN-α/β in hepatitis and cancer.

    Description: The scientific understanding of the driving factors behind zoonotic and pandemic influenzas is hampered by complex interactions between viruses, animal hosts and humans. This complexity makes identifying influenza viruses of high zoonotic or pandemic risk, before they emerge from animal populations, extremely difficult and uncertain. As a first step towards assessing zoonotic risk of influenza, we demonstrate a risk assessment framework to assess the relative likelihood of influenza A viruses, circulating in animal populations, making the species jump into humans. The intention is that such a risk assessment framework could assist decision-makers to compare multiple influenza viruses for zoonotic potential and hence to develop appropriate strain-specific control measures. It also provides a first step towards showing proof of principle for an eventual pandemic risk model. We show that the spatial and temporal epidemiology is as important in assessing the risk of an influenza A species jump as understanding the innate molecular capability of the virus. We also demonstrate data deficiencies that need to be addressed in order to consistently combine both epidemiological and molecular virology data into a risk assessment framework.

    Description: 〈p〉A safety concept and a safety demonstration concept for the disposal of high-level radioactive waste in German clay formations have been developed. The main safety objective is to retain the radionuclides inside a ‘Containment Providing Rock Zone’. Thus, the radionuclide transport should be restrained by adequate safety functions of the geological and geotechnical barriers. The compliance with legal dose constraints has to be demonstrated for probable evolutions and less probable evolutions.〈/p〉 〈p〉As a basis for system analysis, generic geological reference models, disposal concepts and repository designs have been developed for northern and southern Germany. All data relevant for future system evolution were compiled in two FEP (features, events and processes) catalogues. They provide information on FEP characteristics, their probabilities of occurrence, their interactions and identify ‘initial FEP’ that impair the safety functions of relevant barriers. A probable reference scenario has been deduced systematically from the probable ‘initial FEP’, and from probable processes relevant for radionuclide mobilization and transport. Four different starting points to develop alternative scenarios (i.e. less probable evolutions) were identified.〈/p〉 〈p〉The scenario development methodology is applicable to different kinds of host rock and therefore may be a basis for the preliminary safety analyses necessary in the future site selection process in Germany.〈/p〉

    Description: Systematic genetic approaches have provided deep insight into the molecular and cellular mechanisms that operate in simple unicellular organisms. For multicellular organisms, however, the pleiotropy of gene function has largely restricted such approaches to the study of early embryogenesis. With the availability of genome-wide transgenic RNA interference (RNAi) libraries in Drosophila, it is now possible to perform a systematic genetic dissection of any cell or tissue type at any stage of the lifespan. Here we apply these methods to define the genetic basis for formation and function of the Drosophila muscle. We identify a role in muscle for 2,785 genes, many of which we assign to specific functions in the organization of muscles, myofibrils or sarcomeres. Many of these genes are phylogenetically conserved, including genes implicated in mammalian sarcomere organization and human muscle diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schnorrer, Frank -- Schonbauer, Cornelia -- Langer, Christoph C H -- Dietzl, Georg -- Novatchkova, Maria -- Schernhuber, Katharina -- Fellner, Michaela -- Azaryan, Anna -- Radolf, Martin -- Stark, Alexander -- Keleman, Krystyna -- Dickson, Barry J -- England -- Nature. 2010 Mar 11;464(7286):287-91. doi: 10.1038/nature08799.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institute of Biochemistry, Am Klopferspitz 18, 82152 Martinsried, Germany. schnorrer@biochem.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20220848" target="_blank"〉PubMed〈/a〉

    Description: We present a draft genome sequence of the platypus, Ornithorhynchus anatinus. This monotreme exhibits a fascinating combination of reptilian and mammalian characters. For example, platypuses have a coat of fur adapted to an aquatic lifestyle; platypus females lactate, yet lay eggs; and males are equipped with venom similar to that of reptiles. Analysis of the first monotreme genome aligned these features with genetic innovations. We find that reptile and platypus venom proteins have been co-opted independently from the same gene families; milk protein genes are conserved despite platypuses laying eggs; and immune gene family expansions are directly related to platypus biology. Expansions of protein, non-protein-coding RNA and microRNA families, as well as repeat elements, are identified. Sequencing of this genome now provides a valuable resource for deep mammalian comparative analyses, as well as for monotreme biology and conservation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2803040/" 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/PMC2803040/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Wesley C -- Hillier, LaDeana W -- Marshall Graves, Jennifer A -- Birney, Ewan -- Ponting, Chris P -- Grutzner, Frank -- Belov, Katherine -- Miller, Webb -- Clarke, Laura -- Chinwalla, Asif T -- Yang, Shiaw-Pyng -- Heger, Andreas -- Locke, Devin P -- Miethke, Pat -- Waters, Paul D -- Veyrunes, Frederic -- Fulton, Lucinda -- Fulton, Bob -- Graves, Tina -- Wallis, John -- Puente, Xose S -- Lopez-Otin, Carlos -- Ordonez, Gonzalo R -- Eichler, Evan E -- Chen, Lin -- Cheng, Ze -- Deakin, Janine E -- Alsop, Amber -- Thompson, Katherine -- Kirby, Patrick -- Papenfuss, Anthony T -- Wakefield, Matthew J -- Olender, Tsviya -- Lancet, Doron -- Huttley, Gavin A -- Smit, Arian F A -- Pask, Andrew -- Temple-Smith, Peter -- Batzer, Mark A -- Walker, Jerilyn A -- Konkel, Miriam K -- Harris, Robert S -- Whittington, Camilla M -- Wong, Emily S W -- Gemmell, Neil J -- Buschiazzo, Emmanuel -- Vargas Jentzsch, Iris M -- Merkel, Angelika -- Schmitz, Juergen -- Zemann, Anja -- Churakov, Gennady -- Kriegs, Jan Ole -- Brosius, Juergen -- Murchison, Elizabeth P -- Sachidanandam, Ravi -- Smith, Carly -- Hannon, Gregory J -- Tsend-Ayush, Enkhjargal -- McMillan, Daniel -- Attenborough, Rosalind -- Rens, Willem -- Ferguson-Smith, Malcolm -- Lefevre, Christophe M -- Sharp, Julie A -- Nicholas, Kevin R -- Ray, David A -- Kube, Michael -- Reinhardt, Richard -- Pringle, Thomas H -- Taylor, James -- Jones, Russell C -- Nixon, Brett -- Dacheux, Jean-Louis -- Niwa, Hitoshi -- Sekita, Yoko -- Huang, Xiaoqiu -- Stark, Alexander -- Kheradpour, Pouya -- Kellis, Manolis -- Flicek, Paul -- Chen, Yuan -- Webber, Caleb -- Hardison, Ross -- Nelson, Joanne -- Hallsworth-Pepin, Kym -- Delehaunty, Kim -- Markovic, Chris -- Minx, Pat -- Feng, Yucheng -- Kremitzki, Colin -- Mitreva, Makedonka -- Glasscock, Jarret -- Wylie, Todd -- Wohldmann, Patricia -- Thiru, Prathapan -- Nhan, Michael N -- Pohl, Craig S -- Smith, Scott M -- Hou, Shunfeng -- Nefedov, Mikhail -- de Jong, Pieter J -- Renfree, Marilyn B -- Mardis, Elaine R -- Wilson, Richard K -- 062023/Wellcome Trust/United Kingdom -- HG002238/HG/NHGRI NIH HHS/ -- MC_U137761446/Medical Research Council/United Kingdom -- P01 CA013106/CA/NCI NIH HHS/ -- P01 CA013106-37/CA/NCI NIH HHS/ -- R01 GM59290/GM/NIGMS NIH HHS/ -- R01 HG002939/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG004037-02/HG/NHGRI NIH HHS/ -- R01HG02385/HG/NHGRI NIH HHS/ -- Medical Research Council/United Kingdom -- England -- Nature. 2008 May 8;453(7192):175-83. doi: 10.1038/nature06936.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genome Sequencing Center, Washington University School of Medicine, Campus Box 8501, 4444 Forest Park Avenue, St Louis, Missouri 63108, USA. wwarren@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18464734" target="_blank"〉PubMed〈/a〉

    Description: Drosophila endogenous small RNAs are categorized according to their mechanisms of biogenesis and the Argonaute protein to which they bind. MicroRNAs are a class of ubiquitously expressed RNAs of approximately 22 nucleotides in length, which arise from structured precursors through the action of Drosha-Pasha and Dicer-1-Loquacious complexes. These join Argonaute-1 to regulate gene expression. A second endogenous small RNA class, the Piwi-interacting RNAs, bind Piwi proteins and suppress transposons. Piwi-interacting RNAs are restricted to the gonad, and at least a subset of these arises by Piwi-catalysed cleavage of single-stranded RNAs. Here we show that Drosophila generates a third small RNA class, endogenous small interfering RNAs, in both gonadal and somatic tissues. Production of these RNAs requires Dicer-2, but a subset depends preferentially on Loquacious rather than the canonical Dicer-2 partner, R2D2 (ref. 14). Endogenous small interfering RNAs arise both from convergent transcription units and from structured genomic loci in a tissue-specific fashion. They predominantly join Argonaute-2 and have the capacity, as a class, to target both protein-coding genes and mobile elements. These observations expand the repertoire of small RNAs in Drosophila, adding a class that blurs distinctions based on known biogenesis mechanisms and functional roles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2895258/" 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/PMC2895258/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Czech, Benjamin -- Malone, Colin D -- Zhou, Rui -- Stark, Alexander -- Schlingeheyde, Catherine -- Dus, Monica -- Perrimon, Norbert -- Kellis, Manolis -- Wohlschlegel, James A -- Sachidanandam, Ravi -- Hannon, Gregory J -- Brennecke, Julius -- U01 HG004264/HG/NHGRI NIH HHS/ -- U01 HG004264-02/HG/NHGRI NIH HHS/ -- U54 HG004555/HG/NHGRI NIH HHS/ -- U54 HG004555-01/HG/NHGRI NIH HHS/ -- U54 HG004570/HG/NHGRI NIH HHS/ -- U54 HG004570-01/HG/NHGRI NIH HHS/ -- England -- Nature. 2008 Jun 5;453(7196):798-802. doi: 10.1038/nature07007.

    Description: The human body is composed of diverse cell types with distinct functions. Although it is known that lineage specification depends on cell-specific gene expression, which in turn is driven by promoters, enhancers, insulators and other cis-regulatory DNA sequences for each gene, the relative roles of these regulatory elements in this process are not clear. We have previously developed a chromatin-immunoprecipitation-based microarray method (ChIP-chip) to locate promoters, enhancers and insulators in the human genome. Here we use the same approach to identify these elements in multiple cell types and investigate their roles in cell-type-specific gene expression. We observed that the chromatin state at promoters and CTCF-binding at insulators is largely invariant across diverse cell types. In contrast, enhancers are marked with highly cell-type-specific histone modification patterns, strongly correlate to cell-type-specific gene expression programs on a global scale, and are functionally active in a cell-type-specific manner. Our results define over 55,000 potential transcriptional enhancers in the human genome, significantly expanding the current catalogue of human enhancers and highlighting the role of these elements in cell-type-specific gene expression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2910248/" 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/PMC2910248/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heintzman, Nathaniel D -- Hon, Gary C -- Hawkins, R David -- Kheradpour, Pouya -- Stark, Alexander -- Harp, Lindsey F -- Ye, Zhen -- Lee, Leonard K -- Stuart, Rhona K -- Ching, Christina W -- Ching, Keith A -- Antosiewicz-Bourget, Jessica E -- Liu, Hui -- Zhang, Xinmin -- Green, Roland D -- Lobanenkov, Victor V -- Stewart, Ron -- Thomson, James A -- Crawford, Gregory E -- Kellis, Manolis -- Ren, Bing -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG004037-02/HG/NHGRI NIH HHS/ -- U01 HG003151/HG/NHGRI NIH HHS/ -- U01 HG003151-01/HG/NHGRI NIH HHS/ -- U01 HG003151-01S1/HG/NHGRI NIH HHS/ -- U01 HG003151-02/HG/NHGRI NIH HHS/ -- U01 HG003151-03/HG/NHGRI NIH HHS/ -- U01 HG003151-03S1/HG/NHGRI NIH HHS/ -- U01 HG003151-03S2/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2009 May 7;459(7243):108-12. doi: 10.1038/nature07829.
