    Mammalian Y chromosomes retain widely expressed dosage-sensitive regulators (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-04-25
    Description: The human X and Y chromosomes evolved from an ordinary pair of autosomes, but millions of years ago genetic decay ravaged the Y chromosome, and only three per cent of its ancestral genes survived. We reconstructed the evolution of the Y chromosome across eight mammals to identify biases in gene content and the selective pressures that preserved the surviving ancestral genes. Our findings indicate that survival was nonrandom, and in two cases, convergent across placental and marsupial mammals. We conclude that the gene content of the Y chromosome became specialized through selection to maintain the ancestral dosage of homologous X-Y gene pairs that function as broadly expressed regulators of transcription, translation and protein stability. We propose that beyond its roles in testis determination and spermatogenesis, the Y chromosome is essential for male viability, and has unappreciated roles in Turner's syndrome and in phenotypic differences between the sexes in health and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4139287/" 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/PMC4139287/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bellott, Daniel W -- Hughes, Jennifer F -- Skaletsky, Helen -- Brown, Laura G -- Pyntikova, Tatyana -- Cho, Ting-Jan -- Koutseva, Natalia -- Zaghlul, Sara -- Graves, Tina -- Rock, Susie -- Kremitzki, Colin -- Fulton, Robert S -- Dugan, Shannon -- Ding, Yan -- Morton, Donna -- Khan, Ziad -- Lewis, Lora -- Buhay, Christian -- Wang, Qiaoyan -- Watt, Jennifer -- Holder, Michael -- Lee, Sandy -- Nazareth, Lynne -- Alfoldi, Jessica -- Rozen, Steve -- Muzny, Donna M -- Warren, Wesley C -- Gibbs, Richard A -- Wilson, Richard K -- Page, David C -- P51 RR013986/RR/NCRR NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Apr 24;508(7497):494-9. doi: 10.1038/nature13206.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute, Howard Hughes Medical Institute, & Department of Biology, Massachusetts Institute of Technology, Cambridge, Massachusetts 02142, USA. ; The Genome Institute, Washington University School of Medicine, St. Louis, Missouri 63108, USA. ; Human Genome Sequencing Center, Baylor College of Medicine, Houston, Texas 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24759411" target="_blank"〉PubMed〈/a〉

    Whole-genome analysis informs breast cancer response to aromatase inhibition (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-06-23
    Description: To correlate the variable clinical features of oestrogen-receptor-positive breast cancer with somatic alterations, we studied pretreatment tumour biopsies accrued from patients in two studies of neoadjuvant aromatase inhibitor therapy by massively parallel sequencing and analysis. Eighteen significantly mutated genes were identified, including five genes (RUNX1, CBFB, MYH9, MLL3 and SF3B1) previously linked to haematopoietic disorders. Mutant MAP3K1 was associated with luminal A status, low-grade histology and low proliferation rates, whereas mutant TP53 was associated with the opposite pattern. Moreover, mutant GATA3 correlated with suppression of proliferation upon aromatase inhibitor treatment. Pathway analysis demonstrated that mutations in MAP2K4, a MAP3K1 substrate, produced similar perturbations as MAP3K1 loss. Distinct phenotypes in oestrogen-receptor-positive breast cancer are associated with specific patterns of somatic mutations that map into cellular pathways linked to tumour biology, but most recurrent mutations are relatively infrequent. Prospective clinical trials based on these findings will require comprehensive genome sequencing.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3383766/" 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/PMC3383766/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ellis, Matthew J -- Ding, Li -- Shen, Dong -- Luo, Jingqin -- Suman, Vera J -- Wallis, John W -- Van Tine, Brian A -- Hoog, Jeremy -- Goiffon, Reece J -- Goldstein, Theodore C -- Ng, Sam -- Lin, Li -- Crowder, Robert -- Snider, Jacqueline -- Ballman, Karla -- Weber, Jason -- Chen, Ken -- Koboldt, Daniel C -- Kandoth, Cyriac -- Schierding, William S -- McMichael, Joshua F -- Miller, Christopher A -- Lu, Charles -- Harris, Christopher C -- McLellan, Michael D -- Wendl, Michael C -- DeSchryver, Katherine -- Allred, D Craig -- Esserman, Laura -- Unzeitig, Gary -- Margenthaler, Julie -- Babiera, G V -- Marcom, P Kelly -- Guenther, J M -- Leitch, Marilyn -- Hunt, Kelly -- Olson, John -- Tao, Yu -- Maher, Christopher A -- Fulton, Lucinda L -- Fulton, Robert S -- Harrison, Michelle -- Oberkfell, Ben -- Du, Feiyu -- Demeter, Ryan -- Vickery, Tammi L -- Elhammali, Adnan -- Piwnica-Worms, Helen -- McDonald, Sandra -- Watson, Mark -- Dooling, David J -- Ota, David -- Chang, Li-Wei -- Bose, Ron -- Ley, Timothy J -- Piwnica-Worms, David -- Stuart, Joshua M -- Wilson, Richard K -- Mardis, Elaine R -- 3P50 CA68438/CA/NCI NIH HHS/ -- P30 CA091842/CA/NCI NIH HHS/ -- P30 CA091842-01/CA/NCI NIH HHS/ -- P50 CA068438/CA/NCI NIH HHS/ -- P50 CA068438-05/CA/NCI NIH HHS/ -- P50 CA094056/CA/NCI NIH HHS/ -- P50 CA094056-10/CA/NCI NIH HHS/ -- P50 CA94056/CA/NCI NIH HHS/ -- R01 CA095614/CA/NCI NIH HHS/ -- R01 CA095614-01A1/CA/NCI NIH HHS/ -- U01 CA114722/CA/NCI NIH HHS/ -- U01 CA114722-01/CA/NCI NIH HHS/ -- U10 CA076001/CA/NCI NIH HHS/ -- U10 CA076001-13/CA/NCI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003079-04/HG/NHGRI NIH HHS/ -- U54HG003079/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Jun 10;486(7403):353-60. doi: 10.1038/nature11143.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, Division of Oncology, Washington University, St Louis, Missouri 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22722193" target="_blank"〉PubMed〈/a〉

    Novel mutations target distinct subgroups of medulloblastoma (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-06-23
    Description: Medulloblastoma is a malignant childhood brain tumour comprising four discrete subgroups. Here, to identify mutations that drive medulloblastoma, we sequenced the entire genomes of 37 tumours and matched normal blood. One-hundred and thirty-six genes harbouring somatic mutations in this discovery set were sequenced in an additional 56 medulloblastomas. Recurrent mutations were detected in 41 genes not yet implicated in medulloblastoma; several target distinct components of the epigenetic machinery in different disease subgroups, such as regulators of H3K27 and H3K4 trimethylation in subgroups 3 and 4 (for example, KDM6A and ZMYM3), and CTNNB1-associated chromatin re-modellers in WNT-subgroup tumours (for example, SMARCA4 and CREBBP). Modelling of mutations in mouse lower rhombic lip progenitors that generate WNT-subgroup tumours identified genes that maintain this cell lineage (DDX3X), as well as mutated genes that initiate (CDH1) or cooperate (PIK3CA) in tumorigenesis. These data provide important new insights into the pathogenesis of medulloblastoma subgroups and highlight targets for therapeutic development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3412905/" 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/PMC3412905/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robinson, Giles -- Parker, Matthew -- Kranenburg, Tanya A -- Lu, Charles -- Chen, Xiang -- Ding, Li -- Phoenix, Timothy N -- Hedlund, Erin -- Wei, Lei -- Zhu, Xiaoyan -- Chalhoub, Nader -- Baker, Suzanne J -- Huether, Robert -- Kriwacki, Richard -- Curley, Natasha -- Thiruvenkatam, Radhika -- Wang, Jianmin -- Wu, Gang -- Rusch, Michael -- Hong, Xin -- Becksfort, Jared -- Gupta, Pankaj -- Ma, Jing -- Easton, John -- Vadodaria, Bhavin -- Onar-Thomas, Arzu -- Lin, Tong -- Li, Shaoyi -- Pounds, Stanley -- Paugh, Steven -- Zhao, David -- Kawauchi, Daisuke -- Roussel, Martine F -- Finkelstein, David -- Ellison, David W -- Lau, Ching C -- Bouffet, Eric -- Hassall, Tim -- Gururangan, Sridharan -- Cohn, Richard -- Fulton, Robert S -- Fulton, Lucinda L -- Dooling, David J -- Ochoa, Kerri -- Gajjar, Amar -- Mardis, Elaine R -- Wilson, Richard K -- Downing, James R -- Zhang, Jinghui -- Gilbertson, Richard J -- P01 CA096832/CA/NCI NIH HHS/ -- P01CA96832/CA/NCI NIH HHS/ -- P30 CA021765/CA/NCI NIH HHS/ -- P30CA021765/CA/NCI NIH HHS/ -- R01 CA129541/CA/NCI NIH HHS/ -- R01CA129541/CA/NCI NIH HHS/ -- England -- Nature. 2012 Aug 2;488(7409):43-8. doi: 10.1038/nature11213.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉St Jude Children's Research Hospital, Washington University Pediatric Cancer Genome Project, Memphis, Tennessee 38105, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22722829" target="_blank"〉PubMed〈/a〉

    Clonal evolution in relapsed acute myeloid leukaemia revealed by whole-genome sequencing (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-01-13
    Description: Most patients with acute myeloid leukaemia (AML) die from progressive disease after relapse, which is associated with clonal evolution at the cytogenetic level. To determine the mutational spectrum associated with relapse, we sequenced the primary tumour and relapse genomes from eight AML patients, and validated hundreds of somatic mutations using deep sequencing; this allowed us to define clonality and clonal evolution patterns precisely at relapse. In addition to discovering novel, recurrently mutated genes (for example, WAC, SMC3, DIS3, DDX41 and DAXX) in AML, we also found two major clonal evolution patterns during AML relapse: (1) the founding clone in the primary tumour gained mutations and evolved into the relapse clone, or (2) a subclone of the founding clone survived initial therapy, gained additional mutations and expanded at relapse. In all cases, chemotherapy failed to eradicate the founding clone. The comparison of relapse-specific versus primary tumour mutations in all eight cases revealed an increase in transversions, probably due to DNA damage caused by cytotoxic chemotherapy. These data demonstrate that AML relapse is associated with the addition of new mutations and clonal evolution, which is shaped, in part, by the chemotherapy that the patients receive to establish and maintain remissions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3267864/" 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/PMC3267864/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ding, Li -- Ley, Timothy J -- Larson, David E -- Miller, Christopher A -- Koboldt, Daniel C -- Welch, John S -- Ritchey, Julie K -- Young, Margaret A -- Lamprecht, Tamara -- McLellan, Michael D -- McMichael, Joshua F -- Wallis, John W -- Lu, Charles -- Shen, Dong -- Harris, Christopher C -- Dooling, David J -- Fulton, Robert S -- Fulton, Lucinda L -- Chen, Ken -- Schmidt, Heather -- Kalicki-Veizer, Joelle -- Magrini, Vincent J -- Cook, Lisa -- McGrath, Sean D -- Vickery, Tammi L -- Wendl, Michael C -- Heath, Sharon -- Watson, Mark A -- Link, Daniel C -- Tomasson, Michael H -- Shannon, William D -- Payton, Jacqueline E -- Kulkarni, Shashikant -- Westervelt, Peter -- Walter, Matthew J -- Graubert, Timothy A -- Mardis, Elaine R -- Wilson, Richard K -- DiPersio, John F -- P01 CA101937/CA/NCI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003079-10/HG/NHGRI NIH HHS/ -- England -- Nature. 2012 Jan 11;481(7382):506-10. doi: 10.1038/nature10738.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Genome Institute, Washington University, St Louis, Missouri 63108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22237025" target="_blank"〉PubMed〈/a〉

    A catalog of reference genomes from the human microbiome (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-05-22
    Description: The human microbiome refers to the community of microorganisms, including prokaryotes, viruses, and microbial eukaryotes, that populate the human body. The National Institutes of Health launched an initiative that focuses on describing the diversity of microbial species that are associated with health and disease. The first phase of this initiative includes the sequencing of hundreds of microbial reference genomes, coupled to metagenomic sequencing from multiple body sites. Here we present results from an initial reference genome sequencing of 178 microbial genomes. From 547,968 predicted polypeptides that correspond to the gene complement of these strains, previously unidentified ("novel") polypeptides that had both unmasked sequence length greater than 100 amino acids and no BLASTP match to any nonreference entry in the nonredundant subset were defined. This analysis resulted in a set of 30,867 polypeptides, of which 29,987 (approximately 97%) were unique. In addition, this set of microbial genomes allows for approximately 40% of random sequences from the microbiome of the gastrointestinal tract to be associated with organisms based on the match criteria used. Insights into pan-genome analysis suggest that we are still far from saturating microbial species genetic data sets. In addition, the associated metrics and standards used by our group for quality assurance are presented.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2940224/" 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/PMC2940224/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Human Microbiome Jumpstart Reference Strains Consortium -- Nelson, Karen E -- Weinstock, George M -- Highlander, Sarah K -- Worley, Kim C -- Creasy, Heather Huot -- Wortman, Jennifer Russo -- Rusch, Douglas B -- Mitreva, Makedonka -- Sodergren, Erica -- Chinwalla, Asif T -- Feldgarden, Michael -- Gevers, Dirk -- Haas, Brian J -- Madupu, Ramana -- Ward, Doyle V -- Birren, Bruce W -- Gibbs, Richard A -- Methe, Barbara -- Petrosino, Joseph F -- Strausberg, Robert L -- Sutton, Granger G -- White, Owen R -- Wilson, Richard K -- Durkin, Scott -- Giglio, Michelle Gwinn -- Gujja, Sharvari -- Howarth, Clint -- Kodira, Chinnappa D -- Kyrpides, Nikos -- Mehta, Teena -- Muzny, Donna M -- Pearson, Matthew -- Pepin, Kymberlie -- Pati, Amrita -- Qin, Xiang -- Yandava, Chandri -- Zeng, Qiandong -- Zhang, Lan -- Berlin, Aaron M -- Chen, Lei -- Hepburn, Theresa A -- Johnson, Justin -- McCorrison, Jamison -- Miller, Jason -- Minx, Pat -- Nusbaum, Chad -- Russ, Carsten -- Sykes, Sean M -- Tomlinson, Chad M -- Young, Sarah -- Warren, Wesley C -- Badger, Jonathan -- Crabtree, Jonathan -- Markowitz, Victor M -- Orvis, Joshua -- Cree, Andrew -- Ferriera, Steve -- Fulton, Lucinda L -- Fulton, Robert S -- Gillis, Marcus -- Hemphill, Lisa D -- Joshi, Vandita -- Kovar, Christie -- Torralba, Manolito -- Wetterstrand, Kris A -- Abouellleil, Amr -- Wollam, Aye M -- Buhay, Christian J -- Ding, Yan -- Dugan, Shannon -- FitzGerald, Michael G -- Holder, Mike -- Hostetler, Jessica -- Clifton, Sandra W -- Allen-Vercoe, Emma -- Earl, Ashlee M -- Farmer, Candace N -- Liolios, Konstantinos -- Surette, Michael G -- Xu, Qiang -- Pohl, Craig -- Wilczek-Boney, Katarzyna -- Zhu, Dianhui -- HHSN272200900017C/PHS HHS/ -- N01 AI30071/AI/NIAID NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- U54 HG003273-04/HG/NHGRI NIH HHS/ -- U54 HG003273-04S1/HG/NHGRI NIH HHS/ -- U54 HG003273-05/HG/NHGRI NIH HHS/ -- U54 HG003273-05S1/HG/NHGRI NIH HHS/ -- U54 HG003273-05S2/HG/NHGRI NIH HHS/ -- U54 HG003273-06/HG/NHGRI NIH HHS/ -- U54 HG003273-06S1/HG/NHGRI NIH HHS/ -- U54 HG003273-06S2/HG/NHGRI NIH HHS/ -- U54 HG003273-07/HG/NHGRI NIH HHS/ -- U54 HG003273-08/HG/NHGRI NIH HHS/ -- U54 HG004973/HG/NHGRI NIH HHS/ -- U54 HG004973-01/HG/NHGRI NIH HHS/ -- U54 HG004973-02/HG/NHGRI NIH HHS/ -- U54-AI084844/AI/NIAID NIH HHS/ -- U54-HG003079/HG/NHGRI NIH HHS/ -- U54-HG003273/HG/NHGRI NIH HHS/ -- U54-HG004968/HG/NHGRI NIH HHS/ -- U54-HG004969/HG/NHGRI NIH HHS/ -- U54-HG004973/HG/NHGRI NIH HHS/ -- Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2010 May 21;328(5981):994-9. doi: 10.1126/science.1183605.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20489017" target="_blank"〉PubMed〈/a〉

    Role of TP53 mutations in the origin and evolution of therapy-related acute myeloid leukaemia (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-12-10
    Description: Therapy-related acute myeloid leukaemia (t-AML) and therapy-related myelodysplastic syndrome (t-MDS) are well-recognized complications of cytotoxic chemotherapy and/or radiotherapy. There are several features that distinguish t-AML from de novo AML, including a higher incidence of TP53 mutations, abnormalities of chromosomes 5 or 7, complex cytogenetics and a reduced response to chemotherapy. However, it is not clear how prior exposure to cytotoxic therapy influences leukaemogenesis. In particular, the mechanism by which TP53 mutations are selectively enriched in t-AML/t-MDS is unknown. Here, by sequencing the genomes of 22 patients with t-AML, we show that the total number of somatic single-nucleotide variants and the percentage of chemotherapy-related transversions are similar in t-AML and de novo AML, indicating that previous chemotherapy does not induce genome-wide DNA damage. We identified four cases of t-AML/t-MDS in which the exact TP53 mutation found at diagnosis was also present at low frequencies (0.003-0.7%) in mobilized blood leukocytes or bone marrow 3-6 years before the development of t-AML/t-MDS, including two cases in which the relevant TP53 mutation was detected before any chemotherapy. Moreover, functional TP53 mutations were identified in small populations of peripheral blood cells of healthy chemotherapy-naive elderly individuals. Finally, in mouse bone marrow chimaeras containing both wild-type and Tp53(+/-) haematopoietic stem/progenitor cells (HSPCs), the Tp53(+/-) HSPCs preferentially expanded after exposure to chemotherapy. These data suggest that cytotoxic therapy does not directly induce TP53 mutations. Rather, they support a model in which rare HSPCs carrying age-related TP53 mutations are resistant to chemotherapy and expand preferentially after treatment. The early acquisition of TP53 mutations in the founding HSPC clone probably contributes to the frequent cytogenetic abnormalities and poor responses to chemotherapy that are typical of patients with t-AML/t-MDS.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4403236/" 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/PMC4403236/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wong, Terrence N -- Ramsingh, Giridharan -- Young, Andrew L -- Miller, Christopher A -- Touma, Waseem -- Welch, John S -- Lamprecht, Tamara L -- Shen, Dong -- Hundal, Jasreet -- Fulton, Robert S -- Heath, Sharon -- Baty, Jack D -- Klco, Jeffery M -- Ding, Li -- Mardis, Elaine R -- Westervelt, Peter -- DiPersio, John F -- Walter, Matthew J -- Graubert, Timothy A -- Ley, Timothy J -- Druley, Todd E -- Link, Daniel C -- Wilson, Richard K -- K08 HL116605/HL/NHLBI NIH HHS/ -- P01 CA101937/CA/NCI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- England -- Nature. 2015 Feb 26;518(7540):552-5. doi: 10.1038/nature13968.

    C11orf95-RELA fusions drive oncogenic NF-kappaB signalling in ependymoma (2014)

    Description: Members of the nuclear factor-kappaB (NF-kappaB) family of transcriptional regulators are central mediators of the cellular inflammatory response. Although constitutive NF-kappaB signalling is present in most human tumours, mutations in pathway members are rare, complicating efforts to understand and block aberrant NF-kappaB activity in cancer. Here we show that more than two-thirds of supratentorial ependymomas contain oncogenic fusions between RELA, the principal effector of canonical NF-kappaB signalling, and an uncharacterized gene, C11orf95. In each case, C11orf95-RELA fusions resulted from chromothripsis involving chromosome 11q13.1. C11orf95-RELA fusion proteins translocated spontaneously to the nucleus to activate NF-kappaB target genes, and rapidly transformed neural stem cells--the cell of origin of ependymoma--to form these tumours in mice. Our data identify a highly recurrent genetic alteration of RELA in human cancer, and the C11orf95-RELA fusion protein as a potential therapeutic target in supratentorial ependymoma.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4050669/" 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/PMC4050669/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parker, Matthew -- Mohankumar, Kumarasamypet M -- Punchihewa, Chandanamali -- Weinlich, Ricardo -- Dalton, James D -- Li, Yongjin -- Lee, Ryan -- Tatevossian, Ruth G -- Phoenix, Timothy N -- Thiruvenkatam, Radhika -- White, Elsie -- Tang, Bo -- Orisme, Wilda -- Gupta, Kirti -- Rusch, Michael -- Chen, Xiang -- Li, Yuxin -- Nagahawhatte, Panduka -- Hedlund, Erin -- Finkelstein, David -- Wu, Gang -- Shurtleff, Sheila -- Easton, John -- Boggs, Kristy -- Yergeau, Donald -- Vadodaria, Bhavin -- Mulder, Heather L -- Becksfort, Jared -- Gupta, Pankaj -- Huether, Robert -- Ma, Jing -- Song, Guangchun -- Gajjar, Amar -- Merchant, Thomas -- Boop, Frederick -- Smith, Amy A -- Ding, Li -- Lu, Charles -- Ochoa, Kerri -- Zhao, David -- Fulton, Robert S -- Fulton, Lucinda L -- Mardis, Elaine R -- Wilson, Richard K -- Downing, James R -- Green, Douglas R -- Zhang, Jinghui -- Ellison, David W -- Gilbertson, Richard J -- P01 CA096832/CA/NCI NIH HHS/ -- P01CA96832/CA/NCI NIH HHS/ -- P30 CA021765/CA/NCI NIH HHS/ -- P30CA021765/CA/NCI NIH HHS/ -- R01 CA129541/CA/NCI NIH HHS/ -- R01CA129541/CA/NCI NIH HHS/ -- England -- Nature. 2014 Feb 27;506(7489):451-5. doi: 10.1038/nature13109.

    Predatory feeding of two marine mysids (1982)

    Notes: Abstract Predatory feeding of the marine mysids Mysidopsis bigelowi and Neomysis americana on several species of co-occurring copepods was examined in laboratory experiments. M. bigelowi exhibited a curvilinear functional response; there was a negative logarithmic relationship between prey density and clearance rates. N. americana also exhibited higher clearance rates at lower prey densities. Increased clearance rates at lower prey densities were probably due to increased swimming speed or reaction distance as hunger increased. This response occurred only when mysids could visually locate prey; in complete darkness clearance rates were significantly lower and independent of prey density. Feeding rates on different prey species were only partially dependent on prey size; prey movement patterns and escape behavior also strongly affected feeding rates. M. bigelowi showed active prey selection when offered a choice of different prey species. Estimates of predation rates of estuarine mysid populations indicate that they could have a significant effect on co-occurring copepod populations.

    Predatory feeding of the hydromedusae Obelia geniculata and Phialla quadrata (1985)

    Notes: Abstract In 1982–1983 nauplii and adults of several co-occurring copepods and Artemia sp. nauplii (Lake Grassmere, New Zealand strain) were fed to the hydromedusae Obelia geniculata (L.) and Phialella quadrata (Forbes), two species which are very abundant in Wellington Harbour, New Zealand. Clearance rates of both hydromedusae were significantly correlated with predator diameter, but independent of water temperature and prey density. P. quadrata consumed all developmental stages of some copepod species, but O. geniculata consumed only nauplii. Clearance rates of O. geniculata were most strongly related with the strength of the prey escape response, and showed little relation with prey size or movement rates. Clearance rates of P. quadrata were equally influenced by the prey escape response and prey size, but a large amount of the variability in clearance rates could not be explained by any of the prey characteristics, or by a linear combination of the prey characteristics. Clearance rates of the hydromedusae are combined with measures of hydromedusa abundance in Wellington Harbour to calculate daily per capita death rates of the prey.

    Effects of chaetognath predation and nutrient enrichment on enclosed estuarine copepod communities (1984)

    Notes: Summary The effects of predation by the chaetognath Sagitta hispida and nutrient enrichment on estuarine copepod community structure were studied by experimental manipulations in large enclosures. Chaetognath abundance and nutrient addition rates were manipulated in a factorial design. Predation by chaetognaths resulted in a significant decline in the relative abundance of Acartia tonsa and an increase in the relative abundance of Oithona colcarva. However, these effects were evident only at chaetognath densities far higher than observed in natural populations. Nutrient enrichment resulted in a decline in relative abundance of Paracalanus crassirostris, and, in the absence of chaetognath predation, an apparent increase in the relative abundance of A. tonsa. The effects of chaetognath predation were independent of enrichment level, apparently because of the absence of effects of enrichment on total copepod and chaetognath densities.
