Description: The recently released human genome sequences provide us with reference data to conduct comparative genomic research on primates, which will be important to understand what genetic information makes us human. Here we present a first-generation human-chimpanzee comparative genome map and its initial analysis. The map was constructed through paired alignment of 77,461 chimpanzee bacterial artificial chromosome end sequences with publicly available human genome sequences. We detected candidate positions, including two clusters on human chromosome 21 that suggest large, nonrandom regions of difference between the two genomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fujiyama, Asao -- Watanabe, Hidemi -- Toyoda, Atsushi -- Taylor, Todd D -- Itoh, Takehiko -- Tsai, Shih-Feng -- Park, Hong-Seog -- Yaspo, Marie-Laure -- Lehrach, Hans -- Chen, Zhu -- Fu, Gang -- Saitou, Naruya -- Osoegawa, Kazutoyo -- de Jong, Pieter J -- Suto, Yumiko -- Hattori, Masahira -- Sakaki, Yoshiyuki -- New York, N.Y. -- Science. 2002 Jan 4;295(5552):131-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉RIKEN Genomic Sciences Center, 1-7-22 Suehiro-cho, Tsurumi-ku, Yokohama, Kanagawa 230-0045, Japan. afujiyam@gsc.riken.go.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11778049" target="_blank"〉PubMed〈/a〉

Description: The functional complexity of the human transcriptome is not yet fully elucidated. We report a high-throughput sequence of the human transcriptome from a human embryonic kidney and a B cell line. We used shotgun sequencing of transcripts to generate randomly distributed reads. Of these, 50% mapped to unique genomic locations, of which 80% corresponded to known exons. We found that 66% of the polyadenylated transcriptome mapped to known genes and 34% to nonannotated genomic regions. On the basis of known transcripts, RNA-Seq can detect 25% more genes than can microarrays. A global survey of messenger RNA splicing events identified 94,241 splice junctions (4096 of which were previously unidentified) and showed that exon skipping is the most prevalent form of alternative splicing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sultan, Marc -- Schulz, Marcel H -- Richard, Hugues -- Magen, Alon -- Klingenhoff, Andreas -- Scherf, Matthias -- Seifert, Martin -- Borodina, Tatjana -- Soldatov, Aleksey -- Parkhomchuk, Dmitri -- Schmidt, Dominic -- O'Keeffe, Sean -- Haas, Stefan -- Vingron, Martin -- Lehrach, Hans -- Yaspo, Marie-Laure -- New York, N.Y. -- Science. 2008 Aug 15;321(5891):956-60. doi: 10.1126/science.1160342.

Description: Epigenetic alterations, that is, disruption of DNA methylation and chromatin architecture, are now acknowledged as a universal feature of tumorigenesis. Medulloblastoma, a clinically challenging, malignant childhood brain tumour, is no exception. Despite much progress from recent genomics studies, with recurrent changes identified in each of the four distinct tumour subgroups (WNT-pathway-activated, SHH-pathway-activated, and the less-well-characterized Group 3 and Group 4), many cases still lack an obvious genetic driver. Here we present whole-genome bisulphite-sequencing data from thirty-four human and five murine tumours plus eight human and three murine normal controls, augmented with matched whole-genome, RNA and chromatin immunoprecipitation sequencing data. This comprehensive data set allowed us to decipher several features underlying the interplay between the genome, epigenome and transcriptome, and its effects on medulloblastoma pathophysiology. Most notable were highly prevalent regions of hypomethylation correlating with increased gene expression, extending tens of kilobases downstream of transcription start sites. Focal regions of low methylation linked to transcription-factor-binding sites shed light on differential transcriptional networks between subgroups, whereas increased methylation due to re-normalization of repressed chromatin in DNA methylation valleys was positively correlated with gene expression. Large, partially methylated domains affecting up to one-third of the genome showed increased mutation rates and gene silencing in a subgroup-specific fashion. Epigenetic alterations also affected novel medulloblastoma candidate genes (for example, LIN28B), resulting in alternative promoter usage and/or differential messenger RNA/microRNA expression. Analysis of mouse medulloblastoma and precursor-cell methylation demonstrated a somatic origin for many alterations. Our data provide insights into the epigenetic regulation of transcription and genome organization in medulloblastoma pathogenesis, which are probably also of importance in a wider developmental and disease context.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hovestadt, Volker -- Jones, David T W -- Picelli, Simone -- Wang, Wei -- Kool, Marcel -- Northcott, Paul A -- Sultan, Marc -- Stachurski, Katharina -- Ryzhova, Marina -- Warnatz, Hans-Jorg -- Ralser, Meryem -- Brun, Sonja -- Bunt, Jens -- Jager, Natalie -- Kleinheinz, Kortine -- Erkek, Serap -- Weber, Ursula D -- Bartholomae, Cynthia C -- von Kalle, Christof -- Lawerenz, Chris -- Eils, Jurgen -- Koster, Jan -- Versteeg, Rogier -- Milde, Till -- Witt, Olaf -- Schmidt, Sabine -- Wolf, Stephan -- Pietsch, Torsten -- Rutkowski, Stefan -- Scheurlen, Wolfram -- Taylor, Michael D -- Brors, Benedikt -- Felsberg, Jorg -- Reifenberger, Guido -- Borkhardt, Arndt -- Lehrach, Hans -- Wechsler-Reya, Robert J -- Eils, Roland -- Yaspo, Marie-Laure -- Landgraf, Pablo -- Korshunov, Andrey -- Zapatka, Marc -- Radlwimmer, Bernhard -- Pfister, Stefan M -- Lichter, Peter -- England -- Nature. 2014 Jun 26;510(7506):537-41. doi: 10.1038/nature13268.

Description: Medulloblastoma is a highly malignant paediatric brain tumour, often inflicting devastating consequences on the developing child. Genomic studies have revealed four distinct molecular subgroups with divergent biology and clinical behaviour. An understanding of the regulatory circuitry governing the transcriptional landscapes of medulloblastoma subgroups, and how this relates to their respective developmental origins, is lacking. Here, using H3K27ac and BRD4 chromatin immunoprecipitation followed by sequencing (ChIP-seq) coupled with tissue-matched DNA methylation and transcriptome data, we describe the active cis-regulatory landscape across 28 primary medulloblastoma specimens. Analysis of differentially regulated enhancers and super-enhancers reinforced inter-subgroup heterogeneity and revealed novel, clinically relevant insights into medulloblastoma biology. Computational reconstruction of core regulatory circuitry identified a master set of transcription factors, validated by ChIP-seq, that is responsible for subgroup divergence, and implicates candidate cells of origin for Group 4. Our integrated analysis of enhancer elements in a large series of primary tumour samples reveals insights into cis-regulatory architecture, unrecognized dependencies, and cellular origins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Charles Y -- Erkek, Serap -- Tong, Yiai -- Yin, Linlin -- Federation, Alexander J -- Zapatka, Marc -- Haldipur, Parthiv -- Kawauchi, Daisuke -- Risch, Thomas -- Warnatz, Hans-Jorg -- Worst, Barbara C -- Ju, Bensheng -- Orr, Brent A -- Zeid, Rhamy -- Polaski, Donald R -- Segura-Wang, Maia -- Waszak, Sebastian M -- Jones, David T W -- Kool, Marcel -- Hovestadt, Volker -- Buchhalter, Ivo -- Sieber, Laura -- Johann, Pascal -- Chavez, Lukas -- Groschel, Stefan -- Ryzhova, Marina -- Korshunov, Andrey -- Chen, Wenbiao -- Chizhikov, Victor V -- Millen, Kathleen J -- Amstislavskiy, Vyacheslav -- Lehrach, Hans -- Yaspo, Marie-Laure -- Eils, Roland -- Lichter, Peter -- Korbel, Jan O -- Pfister, Stefan M -- Bradner, James E -- Northcott, Paul A -- England -- Nature. 2016 Feb 4;530(7588):57-62. doi: 10.1038/nature16546.

Description: The zebra finch is an important model organism in several fields with unique relevance to human neuroscience. Like other songbirds, the zebra finch communicates through learned vocalizations, an ability otherwise documented only in humans and a few other animals and lacking in the chicken-the only bird with a sequenced genome until now. Here we present a structural, functional and comparative analysis of the genome sequence of the zebra finch (Taeniopygia guttata), which is a songbird belonging to the large avian order Passeriformes. We find that the overall structures of the genomes are similar in zebra finch and chicken, but they differ in many intrachromosomal rearrangements, lineage-specific gene family expansions, the number of long-terminal-repeat-based retrotransposons, and mechanisms of sex chromosome dosage compensation. We show that song behaviour engages gene regulatory networks in the zebra finch brain, altering the expression of long non-coding RNAs, microRNAs, transcription factors and their targets. We also show evidence for rapid molecular evolution in the songbird lineage of genes that are regulated during song experience. These results indicate an active involvement of the genome in neural processes underlying vocal communication and identify potential genetic substrates for the evolution and regulation of this behaviour.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3187626/" 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/PMC3187626/" 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 -- Clayton, David F -- Ellegren, Hans -- Arnold, Arthur P -- Hillier, Ladeana W -- Kunstner, Axel -- Searle, Steve -- White, Simon -- Vilella, Albert J -- Fairley, Susan -- Heger, Andreas -- Kong, Lesheng -- Ponting, Chris P -- Jarvis, Erich D -- Mello, Claudio V -- Minx, Pat -- Lovell, Peter -- Velho, Tarciso A F -- Ferris, Margaret -- Balakrishnan, Christopher N -- Sinha, Saurabh -- Blatti, Charles -- London, Sarah E -- Li, Yun -- Lin, Ya-Chi -- George, Julia -- Sweedler, Jonathan -- Southey, Bruce -- Gunaratne, Preethi -- Watson, Michael -- Nam, Kiwoong -- Backstrom, Niclas -- Smeds, Linnea -- Nabholz, Benoit -- Itoh, Yuichiro -- Whitney, Osceola -- Pfenning, Andreas R -- Howard, Jason -- Volker, Martin -- Skinner, Bejamin M -- Griffin, Darren K -- Ye, Liang -- McLaren, William M -- Flicek, Paul -- Quesada, Victor -- Velasco, Gloria -- Lopez-Otin, Carlos -- Puente, Xose S -- Olender, Tsviya -- Lancet, Doron -- Smit, Arian F A -- Hubley, Robert -- Konkel, Miriam K -- Walker, Jerilyn A -- Batzer, Mark A -- Gu, Wanjun -- Pollock, David D -- Chen, Lin -- Cheng, Ze -- Eichler, Evan E -- Stapley, Jessica -- Slate, Jon -- Ekblom, Robert -- Birkhead, Tim -- Burke, Terry -- Burt, David -- Scharff, Constance -- Adam, Iris -- Richard, Hugues -- Sultan, Marc -- Soldatov, Alexey -- Lehrach, Hans -- Edwards, Scott V -- Yang, Shiaw-Pyng -- Li, Xiaoching -- Graves, Tina -- Fulton, Lucinda -- Nelson, Joanne -- Chinwalla, Asif -- Hou, Shunfeng -- Mardis, Elaine R -- Wilson, Richard K -- BB/D013704/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E010652/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F007590/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBE0175091/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/E/I/00001425/Biotechnology and Biological Sciences Research Council/United Kingdom -- MC_U137761446/Medical Research Council/United Kingdom -- P30 DA018310/DA/NIDA NIH HHS/ -- R01 DC007218/DC/NIDCD NIH HHS/ -- R01 GM059290/GM/NIGMS NIH HHS/ -- R01 GM085233/GM/NIGMS NIH HHS/ -- R01 GM59290/GM/NIGMS NIH HHS/ -- R01 HG002939/HG/NHGRI NIH HHS/ -- R01 NS045264/NS/NINDS NIH HHS/ -- R01NS051820/NS/NINDS NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Apr 1;464(7289):757-62. doi: 10.1038/nature08819.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Genome Center, Washington University School of Medicine, Campus Box 8501, 4444 Forest Park Avenue, St Louis, Missouri 63108, USA. wwarren@watson.wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20360741" target="_blank"〉PubMed〈/a〉
