    The Lkb1 metabolic sensor maintains haematopoietic stem cell survival (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-12-03
    Description: Haematopoietic stem cells (HSCs) can convert between growth states that have marked differences in bioenergetic needs. Although often quiescent in adults, these cells become proliferative upon physiological demand. Balancing HSC energetics in response to nutrient availability and growth state is poorly understood, yet essential for the dynamism of the haematopoietic system. Here we show that the Lkb1 tumour suppressor is critical for the maintenance of energy homeostasis in haematopoietic cells. Lkb1 inactivation in adult mice causes loss of HSC quiescence followed by rapid depletion of all haematopoietic subpopulations. Lkb1-deficient bone marrow cells exhibit mitochondrial defects, alterations in lipid and nucleotide metabolism, and depletion of cellular ATP. The haematopoietic effects are largely independent of Lkb1 regulation of AMP-activated protein kinase (AMPK) and mammalian target of rapamycin (mTOR) signalling. Instead, these data define a central role for Lkb1 in restricting HSC entry into cell cycle and in broadly maintaining energy homeostasis in haematopoietic cells through a novel metabolic checkpoint.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3037591/" 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/PMC3037591/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gurumurthy, Sushma -- Xie, Stephanie Z -- Alagesan, Brinda -- Kim, Judith -- Yusuf, Rushdia Z -- Saez, Borja -- Tzatsos, Alexandros -- Ozsolak, Fatih -- Milos, Patrice -- Ferrari, Francesco -- Park, Peter J -- Shirihai, Orian S -- Scadden, David T -- Bardeesy, Nabeel -- DK050234/DK/NIDDK NIH HHS/ -- R01 DK050234/DK/NIDDK NIH HHS/ -- R01 DK050234-12/DK/NIDDK NIH HHS/ -- R01 DK050234-13/DK/NIDDK NIH HHS/ -- R01 HG005230/HG/NHGRI NIH HHS/ -- R01 HG005230-01/HG/NHGRI NIH HHS/ -- U01 CA141576-01/CA/NCI NIH HHS/ -- England -- Nature. 2010 Dec 2;468(7324):659-63. doi: 10.1038/nature09572.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Center and Center for Regenerative Medicine, Massachusetts General Hospital and Harvard Medical School, Boston, Massachusetts 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21124451" target="_blank"〉PubMed〈/a〉

    RAS-MAPK-MSK1 pathway modulates ataxin 1 protein levels and toxicity in SCA1 (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-05-31
    Description: Many neurodegenerative disorders, such as Alzheimer's, Parkinson's and polyglutamine diseases, share a common pathogenic mechanism: the abnormal accumulation of disease-causing proteins, due to either the mutant protein's resistance to degradation or overexpression of the wild-type protein. We have developed a strategy to identify therapeutic entry points for such neurodegenerative disorders by screening for genetic networks that influence the levels of disease-driving proteins. We applied this approach, which integrates parallel cell-based and Drosophila genetic screens, to spinocerebellar ataxia type 1 (SCA1), a disease caused by expansion of a polyglutamine tract in ataxin 1 (ATXN1). Our approach revealed that downregulation of several components of the RAS-MAPK-MSK1 pathway decreases ATXN1 levels and suppresses neurodegeneration in Drosophila and mice. Importantly, pharmacological inhibitors of components of this pathway also decrease ATXN1 levels, suggesting that these components represent new therapeutic targets in mitigating SCA1. Collectively, these data reveal new therapeutic entry points for SCA1 and provide a proof-of-principle for tackling other classes of intractable neurodegenerative diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4020154/" 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/PMC4020154/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Park, Jeehye -- Al-Ramahi, Ismael -- Tan, Qiumin -- Mollema, Nissa -- Diaz-Garcia, Javier R -- Gallego-Flores, Tatiana -- Lu, Hsiang-Chih -- Lagalwar, Sarita -- Duvick, Lisa -- Kang, Hyojin -- Lee, Yoontae -- Jafar-Nejad, Paymaan -- Sayegh, Layal S -- Richman, Ronald -- Liu, Xiuyun -- Gao, Yan -- Shaw, Chad A -- Arthur, J Simon C -- Orr, Harry T -- Westbrook, Thomas F -- Botas, Juan -- Zoghbi, Huda Y -- HD024064/HD/NICHD NIH HHS/ -- MC_U127081014/Medical Research Council/United Kingdom -- NS42179/NS/NINDS NIH HHS/ -- P30 HD024064/HD/NICHD NIH HHS/ -- R01 NS027699/NS/NINDS NIH HHS/ -- R01 NS042179/NS/NINDS NIH HHS/ -- T32 GM007526/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 Jun 20;498(7454):325-31. doi: 10.1038/nature12204.

    Comprehensive analysis of the chromatin landscape in Drosophila melanogaster (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-12-24
    Description: Chromatin is composed of DNA and a variety of modified histones and non-histone proteins, which have an impact on cell differentiation, gene regulation and other key cellular processes. Here we present a genome-wide chromatin landscape for Drosophila melanogaster based on eighteen histone modifications, summarized by nine prevalent combinatorial patterns. Integrative analysis with other data (non-histone chromatin proteins, DNase I hypersensitivity, GRO-Seq reads produced by engaged polymerase, short/long RNA products) reveals discrete characteristics of chromosomes, genes, regulatory elements and other functional domains. We find that active genes display distinct chromatin signatures that are correlated with disparate gene lengths, exon patterns, regulatory functions and genomic contexts. We also demonstrate a diversity of signatures among Polycomb targets that include a subset with paused polymerase. This systematic profiling and integrative analysis of chromatin signatures provides insights into how genomic elements are regulated, and will serve as a resource for future experimental investigations of genome structure and function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3109908/" 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/PMC3109908/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kharchenko, Peter V -- Alekseyenko, Artyom A -- Schwartz, Yuri B -- Minoda, Aki -- Riddle, Nicole C -- Ernst, Jason -- Sabo, Peter J -- Larschan, Erica -- Gorchakov, Andrey A -- Gu, Tingting -- Linder-Basso, Daniela -- Plachetka, Annette -- Shanower, Gregory -- Tolstorukov, Michael Y -- Luquette, Lovelace J -- Xi, Ruibin -- Jung, Youngsook L -- Park, Richard W -- Bishop, Eric P -- Canfield, Theresa K -- Sandstrom, Richard -- Thurman, Robert E -- MacAlpine, David M -- Stamatoyannopoulos, John A -- Kellis, Manolis -- Elgin, Sarah C R -- Kuroda, Mitzi I -- Pirrotta, Vincenzo -- Karpen, Gary H -- Park, Peter J -- R01 GM071923/GM/NIGMS NIH HHS/ -- R01 GM082798/GM/NIGMS NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R37 GM45744/GM/NIGMS NIH HHS/ -- RC1 HG005334/HG/NHGRI NIH HHS/ -- RC2 HG005639/HG/NHGRI NIH HHS/ -- U01 HG004258/HG/NHGRI NIH HHS/ -- U01 HG004258-04/HG/NHGRI NIH HHS/ -- U01 HG004279/HG/NHGRI NIH HHS/ -- U01HG004258/HG/NHGRI NIH HHS/ -- U54 HG004592/HG/NHGRI NIH HHS/ -- England -- Nature. 2011 Mar 24;471(7339):480-5. doi: 10.1038/nature09725.

    Genome sequencing reveals insights into physiology and longevity of the naked mole rat (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-10-14
    Description: The naked mole rat (Heterocephalus glaber) is a strictly subterranean, extraordinarily long-lived eusocial mammal. Although it is the size of a mouse, its maximum lifespan exceeds 30 years, making this animal the longest-living rodent. Naked mole rats show negligible senescence, no age-related increase in mortality, and high fecundity until death. In addition to delayed ageing, they are resistant to both spontaneous cancer and experimentally induced tumorigenesis. Naked mole rats pose a challenge to the theories that link ageing, cancer and redox homeostasis. Although characterized by significant oxidative stress, the naked mole rat proteome does not show age-related susceptibility to oxidative damage or increased ubiquitination. Naked mole rats naturally reside in large colonies with a single breeding female, the 'queen', who suppresses the sexual maturity of her subordinates. They also live in full darkness, at low oxygen and high carbon dioxide concentrations, and are unable to sustain thermogenesis nor feel certain types of pain. Here we report the sequencing and analysis of the naked mole rat genome, which reveals unique genome features and molecular adaptations consistent with cancer resistance, poikilothermy, hairlessness and insensitivity to low oxygen, and altered visual function, circadian rythms and taste sensing. This information provides insights into the naked mole rat's exceptional longevity and ability to live in hostile conditions, in the dark and at low oxygen. The extreme traits of the naked mole rat, together with the reported genome and transcriptome information, offer opportunities for understanding ageing and advancing other areas of biological and biomedical research.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3319411/" 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/PMC3319411/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Eun Bae -- Fang, Xiaodong -- Fushan, Alexey A -- Huang, Zhiyong -- Lobanov, Alexei V -- Han, Lijuan -- Marino, Stefano M -- Sun, Xiaoqing -- Turanov, Anton A -- Yang, Pengcheng -- Yim, Sun Hee -- Zhao, Xiang -- Kasaikina, Marina V -- Stoletzki, Nina -- Peng, Chunfang -- Polak, Paz -- Xiong, Zhiqiang -- Kiezun, Adam -- Zhu, Yabing -- Chen, Yuanxin -- Kryukov, Gregory V -- Zhang, Qiang -- Peshkin, Leonid -- Yang, Lan -- Bronson, Roderick T -- Buffenstein, Rochelle -- Wang, Bo -- Han, Changlei -- Li, Qiye -- Chen, Li -- Zhao, Wei -- Sunyaev, Shamil R -- Park, Thomas J -- Zhang, Guojie -- Wang, Jun -- Gladyshev, Vadim N -- AG021518/AG/NIA NIH HHS/ -- AG038004/AG/NIA NIH HHS/ -- CA080946/CA/NCI NIH HHS/ -- R01 AG021518/AG/NIA NIH HHS/ -- R01 AG021518-10/AG/NIA NIH HHS/ -- R01 AG038004/AG/NIA NIH HHS/ -- R01 AG038004-02/AG/NIA NIH HHS/ -- R01 CA080946/CA/NCI NIH HHS/ -- R01 CA080946-11/CA/NCI NIH HHS/ -- England -- Nature. 2011 Oct 12;479(7372):223-7. doi: 10.1038/nature10533.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bioinspired Science, Ewha Womans University, Seoul, 120-750, Korea.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21993625" target="_blank"〉PubMed〈/a〉

    X chromosome dosage compensation via enhanced transcriptional elongation in Drosophila (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-03-04
    Description: The evolution of sex chromosomes has resulted in numerous species in which females inherit two X chromosomes but males have a single X, thus requiring dosage compensation. MSL (Male-specific lethal) complex increases transcription on the single X chromosome of Drosophila males to equalize expression of X-linked genes between the sexes. The biochemical mechanisms used for dosage compensation must function over a wide dynamic range of transcription levels and differential expression patterns. It has been proposed that the MSL complex regulates transcriptional elongation to control dosage compensation, a model subsequently supported by mapping of the MSL complex and MSL-dependent histone 4 lysine 16 acetylation to the bodies of X-linked genes in males, with a bias towards 3' ends. However, experimental analysis of MSL function at the mechanistic level has been challenging owing to the small magnitude of the chromosome-wide effect and the lack of an in vitro system for biochemical analysis. Here we use global run-on sequencing (GRO-seq) to examine the specific effect of the MSL complex on RNA Polymerase II (RNAP II) on a genome-wide level. Results indicate that the MSL complex enhances transcription by facilitating the progression of RNAP II across the bodies of active X-linked genes. Improving transcriptional output downstream of typical gene-specific controls may explain how dosage compensation can be imposed on the diverse set of genes along an entire chromosome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3076316/" 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/PMC3076316/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Larschan, Erica -- Bishop, Eric P -- Kharchenko, Peter V -- Core, Leighton J -- Lis, John T -- Park, Peter J -- Kuroda, Mitzi I -- GM082798/GM/NIGMS NIH HHS/ -- GM45744/GM/NIGMS NIH HHS/ -- HG4845/HG/NHGRI NIH HHS/ -- R01 HG004845/HG/NHGRI NIH HHS/ -- R01 HG004845-01/HG/NHGRI NIH HHS/ -- R01 HG004845-02/HG/NHGRI NIH HHS/ -- R37 GM045744/GM/NIGMS NIH HHS/ -- England -- Nature. 2011 Mar 3;471(7336):115-8. doi: 10.1038/nature09757.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Genetics, Department of Medicine, Brigham and Women's Hospital, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21368835" target="_blank"〉PubMed〈/a〉

    Inhibition of miR-25 improves cardiac contractility in the failing heart (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-03-29
    Description: Heart failure is characterized by a debilitating decline in cardiac function, and recent clinical trial results indicate that improving the contractility of heart muscle cells by boosting intracellular calcium handling might be an effective therapy. MicroRNAs (miRNAs) are dysregulated in heart failure but whether they control contractility or constitute therapeutic targets remains speculative. Using high-throughput functional screening of the human microRNAome, here we identify miRNAs that suppress intracellular calcium handling in heart muscle by interacting with messenger RNA encoding the sarcoplasmic reticulum calcium uptake pump SERCA2a (also known as ATP2A2). Of 875 miRNAs tested, miR-25 potently delayed calcium uptake kinetics in cardiomyocytes in vitro and was upregulated in heart failure, both in mice and humans. Whereas adeno-associated virus 9 (AAV9)-mediated overexpression of miR-25 in vivo resulted in a significant loss of contractile function, injection of an antisense oligonucleotide (antagomiR) against miR-25 markedly halted established heart failure in a mouse model, improving cardiac function and survival relative to a control antagomiR oligonucleotide. These data reveal that increased expression of endogenous miR-25 contributes to declining cardiac function during heart failure and suggest that it might be targeted therapeutically to restore function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4131725/" 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/PMC4131725/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wahlquist, Christine -- Jeong, Dongtak -- Rojas-Munoz, Agustin -- Kho, Changwon -- Lee, Ahyoung -- Mitsuyama, Shinichi -- van Mil, Alain -- Park, Woo Jin -- Sluijter, Joost P G -- Doevendans, Pieter A F -- Hajjar, Roger J -- Mercola, Mark -- HHSN268201000045C/HL/NHLBI NIH HHS/ -- HHSN26820100045C/PHS HHS/ -- P01 HL098053/HL/NHLBI NIH HHS/ -- P01HL098053/HL/NHLBI NIH HHS/ -- P20 HL100396/HL/NHLBI NIH HHS/ -- P20HL100396/HL/NHLBI NIH HHS/ -- P30 AR061303/AR/NIAMS NIH HHS/ -- P30 CA030199/CA/NCI NIH HHS/ -- P30AR061303/AR/NIAMS NIH HHS/ -- P30CA030199/CA/NCI NIH HHS/ -- P50 HL112324/HL/NHLBI NIH HHS/ -- P50HL112324/HL/NHLBI NIH HHS/ -- R01 HL088434/HL/NHLBI NIH HHS/ -- R01 HL093183/HL/NHLBI NIH HHS/ -- R01 HL108176/HL/NHLBI NIH HHS/ -- R01 HL113601/HL/NHLBI NIH HHS/ -- R01HL088434/HL/NHLBI NIH HHS/ -- R01HL093183/HL/NHLBI NIH HHS/ -- R01HL108176/HL/NHLBI NIH HHS/ -- R01HL113601/HL/NHLBI NIH HHS/ -- S10 RR021084/RR/NCRR NIH HHS/ -- England -- Nature. 2014 Apr 24;508(7497):531-5. doi: 10.1038/nature13073.

    Landscape of somatic retrotransposition in human cancers (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-30
    Description: Transposable elements (TEs) are abundant in the human genome, and some are capable of generating new insertions through RNA intermediates. In cancer, the disruption of cellular mechanisms that normally suppress TE activity may facilitate mutagenic retrotranspositions. We performed single-nucleotide resolution analysis of TE insertions in 43 high-coverage whole-genome sequencing data sets from five cancer types. We identified 194 high-confidence somatic TE insertions, as well as thousands of polymorphic TE insertions in matched normal genomes. Somatic insertions were present in epithelial tumors but not in blood or brain cancers. Somatic L1 insertions tend to occur in genes that are commonly mutated in cancer, disrupt the expression of the target genes, and are biased toward regions of cancer-specific DNA hypomethylation, highlighting their potential impact in tumorigenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3656569/" 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/PMC3656569/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Eunjung -- Iskow, Rebecca -- Yang, Lixing -- Gokcumen, Omer -- Haseley, Psalm -- Luquette, Lovelace J 3rd -- Lohr, Jens G -- Harris, Christopher C -- Ding, Li -- Wilson, Richard K -- Wheeler, David A -- Gibbs, Richard A -- Kucherlapati, Raju -- Lee, Charles -- Kharchenko, Peter V -- Park, Peter J -- Cancer Genome Atlas Research Network -- F32 AG039979/AG/NIA NIH HHS/ -- F32AG039979/AG/NIA NIH HHS/ -- K25 AG037596/AG/NIA NIH HHS/ -- K25AG037596/AG/NIA NIH HHS/ -- R01 GM082798/GM/NIGMS NIH HHS/ -- R01GM082798/GM/NIGMS NIH HHS/ -- RC1HG005482/HG/NHGRI NIH HHS/ -- T32 CA009172/CA/NCI NIH HHS/ -- U01 HG005725/HG/NHGRI NIH HHS/ -- U01HG005209/HG/NHGRI NIH HHS/ -- U01HG005725/HG/NHGRI NIH HHS/ -- U24 CA144025/CA/NCI NIH HHS/ -- U24CA144025/CA/NCI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2012 Aug 24;337(6097):967-71. doi: 10.1126/science.1222077.

    Description: Conrad et al. (Reports, 10 August 2012, p. 742) reported a doubling of RNA polymerase II (Pol II) occupancy at X-linked promoters to support 5' recruitment as the key mechanism for dosage compensation in Drosophila. However, they employed an erroneous data-processing step, overestimating Pol II differences. Reanalysis of the data fails to support the authors' model for dosage compensation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3665607/" 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/PMC3665607/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ferrari, F -- Jung, Y L -- Kharchenko, P V -- Plachetka, A -- Alekseyenko, A A -- Kuroda, M I -- Park, P J -- GM45744/GM/NIGMS NIH HHS/ -- R37 GM045744/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Apr 19;340(6130):273. doi: 10.1126/science.1231815.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Biomedical Informatics, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23599463" target="_blank"〉PubMed〈/a〉
