    Generation of transgenic non-human primates with germline transmission (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-05-30
    Description: The common marmoset (Callithrix jacchus) is increasingly attractive for use as a non-human primate animal model in biomedical research. It has a relatively high reproduction rate for a primate, making it potentially suitable for transgenic modification. Although several attempts have been made to produce non-human transgenic primates, transgene expression in the somatic tissues of live infants has not been demonstrated by objective analyses such as polymerase chain reaction with reverse transcription or western blots. Here we show that the injection of a self-inactivating lentiviral vector in sucrose solution into marmoset embryos results in transgenic common marmosets that expressed the transgene in several organs. Notably, we achieved germline transmission of the transgene, and the transgenic offspring developed normally. The successful creation of transgenic marmosets provides a new animal model for human disease that has the great advantage of a close genetic relationship with humans. This model will be valuable to many fields of biomedical research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sasaki, Erika -- Suemizu, Hiroshi -- Shimada, Akiko -- Hanazawa, Kisaburo -- Oiwa, Ryo -- Kamioka, Michiko -- Tomioka, Ikuo -- Sotomaru, Yusuke -- Hirakawa, Reiko -- Eto, Tomoo -- Shiozawa, Seiji -- Maeda, Takuji -- Ito, Mamoru -- Ito, Ryoji -- Kito, Chika -- Yagihashi, Chie -- Kawai, Kenji -- Miyoshi, Hiroyuki -- Tanioka, Yoshikuni -- Tamaoki, Norikazu -- Habu, Sonoko -- Okano, Hideyuki -- Nomura, Tatsuji -- England -- Nature. 2009 May 28;459(7246):523-7. doi: 10.1038/nature08090.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Central Institute for Experimental Animals, 1430 Nogawa, Miyamae-ku, Kawasaki, Kanagawa 216-0001, Japan. esasaki@ciea.or.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19478777" target="_blank"〉PubMed〈/a〉

    alpha-Klotho as a regulator of calcium homeostasis (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-06-16
    Description: alpha-klotho was identified as a gene associated with premature aging-like phenotypes characterized by short lifespan. In mice, we found the molecular association of alpha-Klotho (alpha-Kl) and Na+,K+-adenosine triphosphatase (Na+,K+-ATPase) and provide evidence for an increase of abundance of Na+,K+-ATPase at the plasma membrane. Low concentrations of extracellular free calcium ([Ca2+]e) rapidly induce regulated parathyroid hormone (PTH) secretion in an alpha-Kl- and Na+,K+-ATPase-dependent manner. The increased Na+ gradient created by Na+,K+-ATPase activity might drive the transepithelial transport of Ca2+ in cooperation with ion channels and transporters in the choroid plexus and the kidney. Our findings reveal fundamental roles of alpha-Kl in the regulation of calcium metabolism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Imura, Akihiro -- Tsuji, Yoshihito -- Murata, Miyahiko -- Maeda, Ryota -- Kubota, Koji -- Iwano, Akiko -- Obuse, Chikashi -- Togashi, Kazuya -- Tominaga, Makoto -- Kita, Naoko -- Tomiyama, Ken-ichi -- Iijima, Junko -- Nabeshima, Yoko -- Fujioka, Makio -- Asato, Ryo -- Tanaka, Shinzo -- Kojima, Ken -- Ito, Juichi -- Nozaki, Kazuhiko -- Hashimoto, Nobuo -- Ito, Tetsufumi -- Nishio, Takeshi -- Uchiyama, Takashi -- Fujimori, Toshihiko -- Nabeshima, Yo-ichi -- New York, N.Y. -- Science. 2007 Jun 15;316(5831):1615-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology and Tumor Biology, Graduate School of Medicine, Kyoto University, Kyoto 606-8501, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17569864" target="_blank"〉PubMed〈/a〉

    Detection of T cell responses to a ubiquitous cellular protein in autoimmune disease (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-10-18
    Description: T cells that mediate autoimmune diseases such as rheumatoid arthritis (RA) are difficult to characterize because they are likely to be deleted or inactivated in the thymus if the self antigens they recognize are ubiquitously expressed. One way to obtain and analyze these autoimmune T cells is to alter T cell receptor (TCR) signaling in developing T cells to change their sensitivity to thymic negative selection, thereby allowing their thymic production. From mice thus engineered to generate T cells mediating autoimmune arthritis, we isolated arthritogenic TCRs and characterized the self antigens they recognized. One of them was the ubiquitously expressed 60S ribosomal protein L23a (RPL23A), with which T cells and autoantibodies from RA patients reacted. This strategy may improve our understanding of the underlying drivers of autoimmunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ito, Yoshinaga -- Hashimoto, Motomu -- Hirota, Keiji -- Ohkura, Naganari -- Morikawa, Hiromasa -- Nishikawa, Hiroyoshi -- Tanaka, Atsushi -- Furu, Moritoshi -- Ito, Hiromu -- Fujii, Takao -- Nomura, Takashi -- Yamazaki, Sayuri -- Morita, Akimichi -- Vignali, Dario A A -- Kappler, John W -- Matsuda, Shuichi -- Mimori, Tsuneyo -- Sakaguchi, Noriko -- Sakaguchi, Shimon -- R01 DK089125/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2014 Oct 17;346(6207):363-8. doi: 10.1126/science.1259077.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Pathology, Institute for Frontier Medical Sciences, Kyoto University, Kyoto 606-8507, Japan. ; Department of Experimental Pathology, Institute for Frontier Medical Sciences, Kyoto University, Kyoto 606-8507, Japan.

    Regulation of myosin phosphatase by a specific interaction with cGMP- dependent protein kinase Ialpha (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-11-24
    Description: Contraction and relaxation of smooth muscle are regulated by myosin light-chain kinase and myosin phosphatase through phosphorylation and dephosphorylation of myosin light chains. Cyclic guanosine monophosphate (cGMP)-dependent protein kinase Ialpha (cGKIalpha) mediates physiologic relaxation of vascular smooth muscle in response to nitric oxide and cGMP. It is shown here that cGKIalpha is targeted to the smooth muscle cell contractile apparatus by a leucine zipper interaction with the myosin-binding subunit (MBS) of myosin phosphatase. Uncoupling of the cGKIalpha-MBS interaction prevents cGMP-dependent dephosphorylation of myosin light chain, demonstrating that this interaction is essential to the regulation of vascular smooth muscle cell tone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Surks, H K -- Mochizuki, N -- Kasai, Y -- Georgescu, S P -- Tang, K M -- Ito, M -- Lincoln, T M -- Mendelsohn, M E -- HL09330/HL/NHLBI NIH HHS/ -- HL55309/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1999 Nov 19;286(5444):1583-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Cardiology Research Institute and Cardiology Division, Department of Medicine, Tufts University School of Medicine and New England Medical Center, Boston, MA 02111, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10567269" target="_blank"〉PubMed〈/a〉

    Identification of LFA-1 as a candidate autoantigen in treatment-resistant Lyme arthritis (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-07-31
    Description: Treatment-resistant Lyme arthritis is associated with immune reactivity to outer surface protein A (OspA) of Borrelia burgdorferi, the agent of Lyme disease, and the major histocompatibility complex class II allele DRB1*0401. The immunodominant epitope of OspA for T helper cells was identified. A homology search revealed a peptide from human leukocyte function-associated antigen-1 (hLFA-1) as a candidate autoantigen. Individuals with treatment-resistant Lyme arthritis, but not other forms of arthritis, generated responses to OspA, hLFA-1, and their highly related peptide epitopes. Identification of the initiating bacterial antigen and a cross-reactive autoantigen may provide a model for development of autoimmune disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gross, D M -- Forsthuber, T -- Tary-Lehmann, M -- Etling, C -- Ito, K -- Nagy, Z A -- Field, J A -- Steere, A C -- Huber, B T -- R01 AR20358/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 1998 Jul 31;281(5377):703-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Tufts University, Boston, MA 02111 USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9685265" target="_blank"〉PubMed〈/a〉

    Regulation of myeloid leukaemia by the cell-fate determinant Musashi (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-07-20
    Description: Chronic myelogenous leukaemia (CML) can progress from a slow growing chronic phase to an aggressive blast crisis phase, but the molecular basis of this transition remains poorly understood. Here we have used mouse models of CML to show that disease progression is regulated by the Musashi-Numb signalling axis. Specifically, we find that the chronic phase is marked by high levels of Numb expression whereas the blast crisis phase has low levels of Numb expression, and that ectopic expression of Numb promotes differentiation and impairs advanced-phase disease in vivo. As a possible explanation for the decreased levels of Numb in the blast crisis phase, we show that NUP98-HOXA9, an oncogene associated with blast crisis CML, can trigger expression of the RNA-binding protein Musashi2 (Msi2), which in turn represses Numb. Notably, loss of Msi2 restores Numb expression and significantly impairs the development and propagation of blast crisis CML in vitro and in vivo. Finally we show that Msi2 expression is not only highly upregulated during human CML progression but is also an early indicator of poorer prognosis. These data show that the Musashi-Numb pathway can control the differentiation of CML cells, and raise the possibility that targeting this pathway may provide a new strategy for the therapy of aggressive leukaemias.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2918284/" 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/PMC2918284/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ito, Takahiro -- Kwon, Hyog Young -- Zimdahl, Bryan -- Congdon, Kendra L -- Blum, Jordan -- Lento, William E -- Zhao, Chen -- Lagoo, Anand -- Gerrard, Gareth -- Foroni, Letizia -- Goldman, John -- Goh, Harriet -- Kim, Soo-Hyun -- Kim, Dong-Wook -- Chuah, Charles -- Oehler, Vivian G -- Radich, Jerald P -- Jordan, Craig T -- Reya, Tannishtha -- AI067798/AI/NIAID NIH HHS/ -- CA122206/CA/NCI NIH HHS/ -- CA140371/CA/NCI NIH HHS/ -- CA18029/CA/NCI NIH HHS/ -- DK072234/DK/NIDDK NIH HHS/ -- DK63031/DK/NIDDK NIH HHS/ -- DP1 CA174422/CA/NCI NIH HHS/ -- DP1 OD006430/OD/NIH HHS/ -- DP1 OD006430-01/OD/NIH HHS/ -- DP1 OD006430-02/OD/NIH HHS/ -- DP1OD006430/OD/NIH HHS/ -- HL097767/HL/NHLBI NIH HHS/ -- P01 CA018029/CA/NCI NIH HHS/ -- R01 CA140371/CA/NCI NIH HHS/ -- R01 DK063031/DK/NIDDK NIH HHS/ -- R01 DK063031-01/DK/NIDDK NIH HHS/ -- R01 DK063031-01S1/DK/NIDDK NIH HHS/ -- R01 DK063031-02/DK/NIDDK NIH HHS/ -- R01 DK063031-03/DK/NIDDK NIH HHS/ -- R01 DK063031-04/DK/NIDDK NIH HHS/ -- R01 DK063031-05/DK/NIDDK NIH HHS/ -- R01 DK063031-06/DK/NIDDK NIH HHS/ -- R01 DK063031-07/DK/NIDDK NIH HHS/ -- R01 DK063031-07S1/DK/NIDDK NIH HHS/ -- R01 DK063031-08/DK/NIDDK NIH HHS/ -- R01 DK072234/DK/NIDDK NIH HHS/ -- R01 DK072234-01A1/DK/NIDDK NIH HHS/ -- R01 DK072234-02/DK/NIDDK NIH HHS/ -- R01 DK072234-03/DK/NIDDK NIH HHS/ -- R01 DK072234-04/DK/NIDDK NIH HHS/ -- R01 HL097767/HL/NHLBI NIH HHS/ -- R01 HL097767-01/HL/NHLBI NIH HHS/ -- R01 HL097767-02/HL/NHLBI NIH HHS/ -- T32 GM007184-33/GM/NIGMS NIH HHS/ -- U19 AI067798/AI/NIAID NIH HHS/ -- U19 AI067798-010006/AI/NIAID NIH HHS/ -- U19 AI067798-020006/AI/NIAID NIH HHS/ -- U19 AI067798-030006/AI/NIAID NIH HHS/ -- U19 AI067798-040006/AI/NIAID NIH HHS/ -- U19 AI067798-050006/AI/NIAID NIH HHS/ -- England -- Nature. 2010 Aug 5;466(7307):765-8. doi: 10.1038/nature09171.

    PML targeting eradicates quiescent leukaemia-initiating cells (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-05-13
    Description: The existence of a small population of 'cancer-initiating cells' responsible for tumour maintenance has been firmly demonstrated in leukaemia. This concept is currently being tested in solid tumours. Leukaemia-initiating cells, particularly those that are in a quiescent state, are thought to be resistant to chemotherapy and targeted therapies, resulting in disease relapse. Chronic myeloid leukaemia is a paradigmatic haematopoietic stem cell disease in which the leukaemia-initiating-cell pool is not eradicated by current therapy, leading to disease relapse on drug discontinuation. Here we define the critical role of the promyelocytic leukaemia protein (PML) tumour suppressor in haematopoietic stem cell maintenance, and present a new therapeutic approach for targeting quiescent leukaemia-initiating cells and possibly cancer-initiating cells by pharmacological inhibition of PML.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2712082/" 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/PMC2712082/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ito, Keisuke -- Bernardi, Rosa -- Morotti, Alessandro -- Matsuoka, Sahoko -- Saglio, Giuseppe -- Ikeda, Yasuo -- Rosenblatt, Jacalyn -- Avigan, David E -- Teruya-Feldstein, Julie -- Pandolfi, Pier Paolo -- K99 CA139009/CA/NCI NIH HHS/ -- R00 CA139009/CA/NCI NIH HHS/ -- R37 CA071692/CA/NCI NIH HHS/ -- R37 CA071692-12/CA/NCI NIH HHS/ -- England -- Nature. 2008 Jun 19;453(7198):1072-8. doi: 10.1038/nature07016.

    Developmental and species-divergent globin switching are driven by BCL11A (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-08-07
    Description: The contribution of changes in cis-regulatory elements or trans-acting factors to interspecies differences in gene expression is not well understood. The mammalian beta-globin loci have served as a model for gene regulation during development. Transgenic mice containing the human beta-globin locus, consisting of the linked embryonic (epsilon), fetal (gamma) and adult (beta) genes, have been used as a system to investigate the temporal switch from fetal to adult haemoglobin, as occurs in humans. Here we show that the human gamma-globin (HBG) genes in these mice behave as murine embryonic globin genes, revealing a limitation of the model and demonstrating that critical differences in the trans-acting milieu have arisen during mammalian evolution. We show that the expression of BCL11A, a repressor of human gamma-globin expression identified by genome-wide association studies, differs between mouse and human. Developmental silencing of the mouse embryonic globin and human gamma-globin genes fails to occur in mice in the absence of BCL11A. Thus, BCL11A is a critical mediator of species-divergent globin switching. By comparing the ontogeny of beta-globin gene regulation in mice and humans, we have shown that alterations in the expression of a trans-acting factor constitute a critical driver of gene expression changes during evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3749913/" 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/PMC3749913/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sankaran, Vijay G -- Xu, Jian -- Ragoczy, Tobias -- Ippolito, Gregory C -- Walkley, Carl R -- Maika, Shanna D -- Fujiwara, Yuko -- Ito, Masafumi -- Groudine, Mark -- Bender, M A -- Tucker, Philip W -- Orkin, Stuart H -- P01 HL032262/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 Aug 27;460(7259):1093-7. doi: 10.1038/nature08243.

    Description: The post-translational modifications of histone tails generate a 'histone code' that defines local and global chromatin states. The resultant regulation of gene function is thought to govern cell fate, proliferation and differentiation. Reversible histone modifications such as methylation are under mutual controls to organize chromosomal events. Among the histone modifications, methylation of specific lysine and arginine residues seems to be critical for chromatin configuration and control of gene expression. Methylation of histone H3 lysine 4 (H3K4) changes chromatin into a transcriptionally active state. Reversible modification of proteins by beta-N-acetylglucosamine (O-GlcNAc) in response to serum glucose levels regulates diverse cellular processes. However, the epigenetic impact of protein GlcNAcylation is unknown. Here we report that nuclear GlcNAcylation of a histone lysine methyltransferase (HKMT), MLL5, by O-GlcNAc transferase facilitates retinoic-acid-induced granulopoiesis in human HL60 promyelocytes through methylation of H3K4. MLL5 is biochemically identified in a GlcNAcylation-dependent multi-subunit complex associating with nuclear retinoic acid receptor RARalpha (also known as RARA), serving as a mono- and di-methyl transferase to H3K4. GlcNAcylation at Thr 440 in the MLL5 SET domain evokes its H3K4 HKMT activity and co-activates RARalpha in target gene promoters. Increased nuclear GlcNAcylation by means of O-GlcNAc transferase potentiates retinoic-acid-induced HL60 granulopoiesis and restores the retinoic acid response in the retinoic-acid-resistant HL60-R2 cell line. Thus, nuclear MLL5 GlcNAcylation triggers cell lineage determination of HL60 through activation of its HKMT activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fujiki, Ryoji -- Chikanishi, Toshihiro -- Hashiba, Waka -- Ito, Hiroaki -- Takada, Ichiro -- Roeder, Robert G -- Kitagawa, Hirochika -- Kato, Shigeaki -- England -- Nature. 2009 May 21;459(7245):455-9. doi: 10.1038/nature07954.
