    Global epigenomic reconfiguration during mammalian brain development (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-07-06
    Description: DNA methylation is implicated in mammalian brain development and plasticity underlying learning and memory. We report the genome-wide composition, patterning, cell specificity, and dynamics of DNA methylation at single-base resolution in human and mouse frontal cortex throughout their lifespan. Widespread methylome reconfiguration occurs during fetal to young adult development, coincident with synaptogenesis. During this period, highly conserved non-CG methylation (mCH) accumulates in neurons, but not glia, to become the dominant form of methylation in the human neuronal genome. Moreover, we found an mCH signature that identifies genes escaping X-chromosome inactivation. Last, whole-genome single-base resolution 5-hydroxymethylcytosine (hmC) maps revealed that hmC marks fetal brain cell genomes at putative regulatory regions that are CG-demethylated and activated in the adult brain and that CG demethylation at these hmC-poised loci depends on Tet2 activity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3785061/" 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/PMC3785061/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lister, Ryan -- Mukamel, Eran A -- Nery, Joseph R -- Urich, Mark -- Puddifoot, Clare A -- Johnson, Nicholas D -- Lucero, Jacinta -- Huang, Yun -- Dwork, Andrew J -- Schultz, Matthew D -- Yu, Miao -- Tonti-Filippini, Julian -- Heyn, Holger -- Hu, Shijun -- Wu, Joseph C -- Rao, Anjana -- Esteller, Manel -- He, Chuan -- Haghighi, Fatemeh G -- Sejnowski, Terrence J -- Behrens, M Margarita -- Ecker, Joseph R -- AI44432/AI/NIAID NIH HHS/ -- CA151535/CA/NCI NIH HHS/ -- HD065812/HD/NICHD NIH HHS/ -- HG006827/HG/NHGRI NIH HHS/ -- K99NS080911/NS/NINDS NIH HHS/ -- MH094670/MH/NIMH NIH HHS/ -- R01 AI044432/AI/NIAID NIH HHS/ -- R01 CA151535/CA/NCI NIH HHS/ -- R01 HD065812/HD/NICHD NIH HHS/ -- R01 HG006827/HG/NHGRI NIH HHS/ -- R01 MH094670/MH/NIMH NIH HHS/ -- R01 MH094774/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Aug 9;341(6146):1237905. doi: 10.1126/science.1237905.

    Genome-wide mapping of 5-hydroxymethylcytosine in embryonic stem cells (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-05-10
    Description: 5-hydroxymethylcytosine (5hmC) is a modified base present at low levels in diverse cell types in mammals. 5hmC is generated by the TET family of Fe(II) and 2-oxoglutarate-dependent enzymes through oxidation of 5-methylcytosine (5mC). 5hmC and TET proteins have been implicated in stem cell biology and cancer, but information on the genome-wide distribution of 5hmC is limited. Here we describe two novel and specific approaches to profile the genomic localization of 5hmC. The first approach, termed GLIB (glucosylation, periodate oxidation, biotinylation) uses a combination of enzymatic and chemical steps to isolate DNA fragments containing as few as a single 5hmC. The second approach involves conversion of 5hmC to cytosine 5-methylenesulphonate (CMS) by treatment of genomic DNA with sodium bisulphite, followed by immunoprecipitation of CMS-containing DNA with a specific antiserum to CMS. High-throughput sequencing of 5hmC-containing DNA from mouse embryonic stem (ES) cells showed strong enrichment within exons and near transcriptional start sites. 5hmC was especially enriched at the start sites of genes whose promoters bear dual histone 3 lysine 27 trimethylation (H3K27me3) and histone 3 lysine 4 trimethylation (H3K4me3) marks. Our results indicate that 5hmC has a probable role in transcriptional regulation, and suggest a model in which 5hmC contributes to the 'poised' chromatin signature found at developmentally-regulated genes in ES cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3124347/" 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/PMC3124347/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pastor, William A -- Pape, Utz J -- Huang, Yun -- Henderson, Hope R -- Lister, Ryan -- Ko, Myunggon -- McLoughlin, Erin M -- Brudno, Yevgeny -- Mahapatra, Sahasransu -- Kapranov, Philipp -- Tahiliani, Mamta -- Daley, George Q -- Liu, X Shirley -- Ecker, Joseph R -- Milos, Patrice M -- Agarwal, Suneet -- Rao, Anjana -- 1 R01 HD065812-01A1/HD/NICHD NIH HHS/ -- 1 UL1 RR 025758-02/RR/NCRR NIH HHS/ -- K08 HL089150/HL/NHLBI NIH HHS/ -- K08 HL089150-01A1/HL/NHLBI NIH HHS/ -- R01 AI044432/AI/NIAID NIH HHS/ -- R01 AI044432-10/AI/NIAID NIH HHS/ -- R01 AI44432/AI/NIAID NIH HHS/ -- R01 HD065812/HD/NICHD NIH HHS/ -- R01 HD065812-01A1/HD/NICHD NIH HHS/ -- RC1 DA028422/DA/NIDA NIH HHS/ -- RC1 DA028422-02/DA/NIDA NIH HHS/ -- UL1 RR025758/RR/NCRR NIH HHS/ -- England -- Nature. 2011 May 19;473(7347):394-7. doi: 10.1038/nature10102.

    Hotspots of aberrant epigenomic reprogramming in human induced pluripotent stem cells (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-02-04
    Description: Induced pluripotent stem cells (iPSCs) offer immense potential for regenerative medicine and studies of disease and development. Somatic cell reprogramming involves epigenomic reconfiguration, conferring iPSCs with characteristics similar to embryonic stem (ES) cells. However, it remains unknown how complete the reestablishment of ES-cell-like DNA methylation patterns is throughout the genome. Here we report the first whole-genome profiles of DNA methylation at single-base resolution in five human iPSC lines, along with methylomes of ES cells, somatic cells, and differentiated iPSCs and ES cells. iPSCs show significant reprogramming variability, including somatic memory and aberrant reprogramming of DNA methylation. iPSCs share megabase-scale differentially methylated regions proximal to centromeres and telomeres that display incomplete reprogramming of non-CG methylation, and differences in CG methylation and histone modifications. Lastly, differentiation of iPSCs into trophoblast cells revealed that errors in reprogramming CG methylation are transmitted at a high frequency, providing an iPSC reprogramming signature that is maintained after differentiation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3100360/" 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/PMC3100360/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lister, Ryan -- Pelizzola, Mattia -- Kida, Yasuyuki S -- Hawkins, R David -- Nery, Joseph R -- Hon, Gary -- Antosiewicz-Bourget, Jessica -- O'Malley, Ronan -- Castanon, Rosa -- Klugman, Sarit -- Downes, Michael -- Yu, Ruth -- Stewart, Ron -- Ren, Bing -- Thomson, James A -- Evans, Ronald M -- Ecker, Joseph R -- 1U01ES017166-01/ES/NIEHS NIH HHS/ -- DK062434/DK/NIDDK NIH HHS/ -- P30 CA014195/CA/NCI NIH HHS/ -- U01 ES017166/ES/NIEHS NIH HHS/ -- U01 ES017166-01/ES/NIEHS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Mar 3;471(7336):68-73. doi: 10.1038/nature09798.

    Oxford University Press
    Details
    Publication Date: 2013-11-29
    Description: Motivation: Easily visualization of complex data features is a necessary step to conduct studies on next-generation sequencing (NGS) data. We developed STAR, an integrated web application that enables online management, visualization and track-based analysis of NGS data. Results: STAR is a multilayer web service system. On the client side, STAR leverages JavaScript, HTML5 Canvas and asynchronous communications to deliver a smoothly scrolling desktop-like graphical user interface with a suite of in-browser analysis tools that range from providing simple track configuration controls to sophisticated feature detection within datasets. On the server side, STAR supports private session state retention via an account management system and provides data management modules that enable collection, visualization and analysis of third-party sequencing data from the public domain with over thousands of tracks hosted to date. Overall, STAR represents a next-generation data exploration solution to match the requirements of NGS data, enabling both intuitive visualization and dynamic analysis of data. Availability and implementation: STAR browser system is freely available on the web at http://wanglab.ucsd.edu/star/browser and https://github.com/angell1117/STAR-genome-browser .
