    Protein synthesis and neurotrophin-dependent structural plasticity of single dendritic spines (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-03-01
    Description: Long-term potentiation (LTP) at glutamatergic synapses is considered to underlie learning and memory and is associated with the enlargement of dendritic spines. Because the consolidation of memory and LTP require protein synthesis, it is important to clarify how protein synthesis affects spine enlargement. In rat brain slices, the repetitive pairing of postsynaptic spikes and two-photon uncaging of glutamate at single spines (a spike-timing protocol) produced both immediate and gradual phases of spine enlargement in CA1 pyramidal neurons. The gradual enlargement was strongly dependent on protein synthesis and brain-derived neurotrophic factor (BDNF) action, often associated with spine twitching, and was induced specifically at the spines that were immediately enlarged by the synaptic stimulation. Thus, this spike-timing protocol is an efficient trigger for BDNF secretion and induces protein synthesis-dependent long-term enlargement at the level of single spines.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4218863/" 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/PMC4218863/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanaka, Jun-Ichi -- Horiike, Yoshihiro -- Matsuzaki, Masanori -- Miyazaki, Takashi -- Ellis-Davies, Graham C R -- Kasai, Haruo -- R01 GM053395/GM/NIGMS NIH HHS/ -- R01 GM053395-12/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Mar 21;319(5870):1683-7. doi: 10.1126/science.1152864.

    Design logic of a cannabinoid receptor signaling network that triggers neurite outgrowth (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-05-20
    Description: Cannabinoid receptor 1 (CB1R) regulates neuronal differentiation. To understand the logic underlying decision-making in the signaling network controlling CB1R-induced neurite outgrowth, we profiled the activation of several hundred transcription factors after cell stimulation. We assembled an in silico signaling network by connecting CB1R to 23 activated transcription factors. Statistical analyses of this network predicted a role for the breast cancer 1 protein BRCA1 in neuronal differentiation and a new pathway from CB1R through phosphoinositol 3-kinase to the transcription factor paired box 6 (PAX6). Both predictions were experimentally confirmed. Results of transcription factor activation experiments that used pharmacological inhibitors of kinases revealed a network organization of partial OR gates regulating kinases stacked above AND gates that control transcription factors, which together allow for distributed decision-making in CB1R-induced neurite outgrowth.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2776723/" 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/PMC2776723/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bromberg, Kenneth D -- Ma'ayan, Avi -- Neves, Susana R -- Iyengar, Ravi -- 1 S10 RR0 9145-01/RR/NCRR NIH HHS/ -- 5R24 CA095823-04/CA/NCI NIH HHS/ -- GM072853/GM/NIGMS NIH HHS/ -- GM54508/GM/NIGMS NIH HHS/ -- P50 GM071558/GM/NIGMS NIH HHS/ -- P50 GM071558-01A2/GM/NIGMS NIH HHS/ -- P50 GM071558-01A20007/GM/NIGMS NIH HHS/ -- P50 GM071558-02/GM/NIGMS NIH HHS/ -- P50 GM071558-020007/GM/NIGMS NIH HHS/ -- P50 GM071558-030007/GM/NIGMS NIH HHS/ -- P50-071558/PHS HHS/ -- R01 GM054508/GM/NIGMS NIH HHS/ -- R01 GM054508-21/GM/NIGMS NIH HHS/ -- R01 GM072853/GM/NIGMS NIH HHS/ -- R01 GM072853-04/GM/NIGMS NIH HHS/ -- T32 CA88796/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 May 16;320(5878):903-9. doi: 10.1126/science.1152662.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology and Systems Therapeutics, Mount Sinai School of Medicine, New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18487186" target="_blank"〉PubMed〈/a〉

    Intersection of the RNA interference and X-inactivation pathways (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-06-07
    Description: In mammals, dosage compensation is achieved by X-chromosome inactivation (XCI) in the female. The noncoding Xist gene initiates silencing of the X chromosome, whereas its antisense partner Tsix blocks silencing. The complementarity of Xist and Tsix RNAs has long suggested a role for RNA interference (RNAi). Here, we report that murine Xist and Tsix form duplexes in vivo. During XCI, the duplexes are processed to small RNAs (sRNAs), most likely on the active X (Xa) in a Dicer-dependent manner. Deleting Dicer compromises sRNA production and derepresses Xist. Furthermore, without Dicer, Xist RNA cannot accumulate and histone 3 lysine 27 trimethylation is blocked on the inactive X (Xi). The defects are partially rescued by truncating Tsix. Thus, XCI and RNAi intersect, down-regulating Xist on Xa and spreading silencing on Xi.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2584363/" 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/PMC2584363/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ogawa, Yuya -- Sun, Bryan K -- Lee, Jeannie T -- R01 GM058839/GM/NIGMS NIH HHS/ -- R01 GM058839-10/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Jun 6;320(5881):1336-41. doi: 10.1126/science.1157676.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Massachusetts General Hospital and Howard Hughes Medical Institute, Boston, MA 02114, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18535243" target="_blank"〉PubMed〈/a〉

    Hepatic glucose sensing via the CREB coactivator CRTC2 (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-03-08
    Description: Chronic hyperglycemia contributes to the development of diabetes-associated complications. Increases in the concentration of circulating glucose activate the hexosamine biosynthetic pathway (HBP) and promote the O-glycosylation of proteins by O-glycosyl transferase (OGT). We show that OGT triggered hepatic gluconeogenesis through the O-glycosylation of the transducer of regulated cyclic adenosine monophosphate response element-binding protein (CREB) 2 (TORC2 or CRTC2). CRTC2 was O-glycosylated at sites that normally sequester CRTC2 in the cytoplasm through a phosphorylation-dependent mechanism. Decreasing amounts of O-glycosylated CRTC2 by expression of the deglycosylating enzyme O-GlcNAcase blocked effects of glucose on gluconeogenesis, demonstrating the importance of the HBP in the development of glucose intolerance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dentin, Renaud -- Hedrick, Susan -- Xie, Jianxin -- Yates, John 3rd -- Montminy, Marc -- R01 GM037828/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Mar 7;319(5868):1402-5. doi: 10.1126/science.1151363.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Salk Institute for Biological Studies, 10010 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18323454" target="_blank"〉PubMed〈/a〉

    A model for neuronal competition during development (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-03-08
    Description: We report that developmental competition between sympathetic neurons for survival is critically dependent on a sensitization process initiated by target innervation and mediated by a series of feedback loops. Target-derived nerve growth factor (NGF) promoted expression of its own receptor TrkA in mouse and rat neurons and prolonged TrkA-mediated signals. NGF also controlled expression of brain-derived neurotrophic factor and neurotrophin-4, which, through the receptor p75, can kill neighboring neurons with low retrograde NGF-TrkA signaling whereas neurons with high NGF-TrkA signaling are protected. Perturbation of any of these feedback loops disrupts the dynamics of competition. We suggest that three target-initiated events are essential for rapid and robust competition between neurons: sensitization, paracrine apoptotic signaling, and protection from such effects.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612357/" 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/PMC3612357/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deppmann, Christopher D -- Mihalas, Stefan -- Sharma, Nikhil -- Lonze, Bonnie E -- Niebur, Ernst -- Ginty, David D -- EY016281/EY/NEI NIH HHS/ -- F32 NS053187/NS/NINDS NIH HHS/ -- NS053187/NS/NINDS NIH HHS/ -- NS34814/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Apr 18;320(5874):369-73. doi: 10.1126/science.1152677.

    Ankyrin repeat proteins comprise a diverse family of bacterial type IV effectors (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-06-21
    Description: Specialized secretion systems are used by many bacteria to deliver effector proteins into host cells that can either mimic or disrupt the function of eukaryotic factors. We found that the intracellular pathogens Legionella pneumophila and Coxiella burnetii use a type IV secretion system to deliver into eukaryotic cells a large number of different bacterial proteins containing ankyrin repeat homology domains called Anks. The L. pneumophila AnkX protein prevented microtubule-dependent vesicular transport to interfere with fusion of the L. pneumophila-containing vacuole with late endosomes after infection of macrophages, which demonstrates that Ank proteins have effector functions important for bacterial infection of eukaryotic host cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2514061/" 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/PMC2514061/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pan, Xiaoxiao -- Luhrmann, Anja -- Satoh, Ayano -- Laskowski-Arce, Michelle A -- Roy, Craig R -- AG030101/AG/NIA NIH HHS/ -- AI041699/AI/NIAID NIH HHS/ -- AI064559/AI/NIAID NIH HHS/ -- GM060919/GM/NIGMS NIH HHS/ -- R01 AI041699/AI/NIAID NIH HHS/ -- R01 AI041699-12/AI/NIAID NIH HHS/ -- R01 AI064559/AI/NIAID NIH HHS/ -- R01 AI064559-03/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2008 Jun 20;320(5883):1651-4. doi: 10.1126/science.1158160.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Microbial Pathogenesis, Yale University School of Medicine, 295 Congress Avenue, New Haven, CT 06536, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18566289" target="_blank"〉PubMed〈/a〉

    Traction dynamics of filopodia on compliant substrates (2008)

    Details
    Publication Date: 2008-12-17
    Description: Cells sense the environment's mechanical stiffness to control their own shape, migration, and fate. To better understand stiffness sensing, we constructed a stochastic model of the "motor-clutch" force transmission system, where molecular clutches link F-actin to the substrate and mechanically resist myosin-driven F-actin retrograde flow. The model predicts two distinct regimes: (i) "frictional slippage," with fast retrograde flow and low traction forces on stiff substrates and (ii) oscillatory "load-and-fail" dynamics, with slower retrograde flow and higher traction forces on soft substrates. We experimentally confirmed these model predictions in embryonic chick forebrain neurons by measuring the nanoscale dynamics of single-growth-cone filopodia. Furthermore, we experimentally observed a model-predicted switch in F-actin dynamics around an elastic modulus of 1 kilopascal. Thus, a motor-clutch system inherently senses and responds to the mechanical stiffness of the local environment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, Clarence E -- Odde, David J -- R01-GM-76177/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Dec 12;322(5908):1687-91. doi: 10.1126/science.1163595.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biomedical Engineering, University of Minnesota, Minneapolis, MN 55455, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19074349" target="_blank"〉PubMed〈/a〉

    Adenovirus small e1a alters global patterns of histone modification (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-08-23
    Description: Adenovirus small early region 1a (e1a) protein drives cells into S phase by binding RB family proteins and the closely related histone acetyl transferases p300 and CBP. The interaction with RB proteins displaces them from DNA-bound E2F transcription factors, reversing their repression of cell cycle genes. However, it has been unclear how the e1a interaction with p300 and CBP promotes passage through the cell cycle. We show that this interaction causes a threefold reduction in total cellular histone H3 lysine 18 acetylation (H3K18ac). CBP and p300 are required for acetylation at this site because their knockdown causes specific hypoacetylation at H3K18. SV40 T antigen also induces H3K18 hypoacetylation. Because global hypoacetylation at this site is observed in prostate carcinomas with poor prognosis, this suggests that processes resulting in global H3K18 hypoacetylation may be linked to oncogenic transformation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756290/" 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/PMC2756290/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Horwitz, Gregory A -- Zhang, Kangling -- McBrian, Matthew A -- Grunstein, Michael -- Kurdistani, Siavash K -- Berk, Arnold J -- CA25235/CA/NCI NIH HHS/ -- R37 CA025235/CA/NCI NIH HHS/ -- R37 CA025235-30/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 Aug 22;321(5892):1084-5. doi: 10.1126/science.1155544.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology Institute, University of California, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18719283" target="_blank"〉PubMed〈/a〉

    Description: Hepatic glucose production is critical for basal brain function and survival when dietary glucose is unavailable. Glucose-6-phosphatase (G6Pase) is an essential, rate-limiting enzyme that serves as a terminal gatekeeper for hepatic glucose release into the plasma. Mutations in G6Pase result in Von Gierke's disease (glycogen storage disease-1a), a potentially fatal genetic disorder. We have identified the transcriptional coactivator SRC-2 as a regulator of fasting hepatic glucose release, a function that SRC-2 performs by controlling the expression of hepatic G6Pase. SRC-2 modulates G6Pase expression directly by acting as a coactivator with the orphan nuclear receptor RORalpha. In addition, SRC-2 ablation, in both a whole-body and liver-specific manner, resulted in a Von Gierke's disease phenotype in mice. Our results position SRC-2 as a critical regulator of mammalian glucose production.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2668604/" 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/PMC2668604/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chopra, Atul R -- Louet, Jean-Francois -- Saha, Pradip -- An, Jie -- Demayo, Franco -- Xu, Jianming -- York, Brian -- Karpen, Saul -- Finegold, Milton -- Moore, David -- Chan, Lawrence -- Newgard, Christopher B -- O'Malley, Bert W -- DK58242/DK/NIDDK NIH HHS/ -- HL51586/HL/NHLBI NIH HHS/ -- P01 DK059820/DK/NIDDK NIH HHS/ -- P01 DK059820-08/DK/NIDDK NIH HHS/ -- P01 DK58398/DK/NIDDK NIH HHS/ -- P01 DK59820/DK/NIDDK NIH HHS/ -- R01 DK056239/DK/NIDDK NIH HHS/ -- R01 DK056239-08/DK/NIDDK NIH HHS/ -- U19 DK062434/DK/NIDDK NIH HHS/ -- U19 DK062434-07/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2008 Nov 28;322(5906):1395-9. doi: 10.1126/science.1164847.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, Baylor College of Medicine, 1 Baylor Plaza, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19039140" target="_blank"〉PubMed〈/a〉
