    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)
    American Association for the Advancement of Science (AAAS)
    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〉

    Absence of the SRC-2 coactivator results in a glycogenopathy resembling Von Gierke's disease (2008)

    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〉

    Leiomodin is an actin filament nucleator in muscle cells (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-04-12
    Description: Initiation of actin polymerization in cells requires nucleation factors. Here we describe an actin-binding protein, leiomodin, that acted as a strong filament nucleator in muscle cells. Leiomodin shared two actin-binding sites with the filament pointed end-capping protein tropomodulin: a flexible N-terminal region and a leucine-rich repeat domain. Leiomodin also contained a C-terminal extension of 150 residues. The smallest fragment with strong nucleation activity included the leucine-rich repeat and C-terminal extension. The N-terminal region enhanced the nucleation activity threefold and recruited tropomyosin, which weakly stimulated nucleation and mediated localization of leiomodin to the middle of muscle sarcomeres. Knocking down leiomodin severely compromised sarcomere assembly in cultured muscle cells, which suggests a role for leiomodin in the nucleation of tropomyosin-decorated filaments in muscles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2845909/" 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/PMC2845909/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chereau, David -- Boczkowska, Malgorzata -- Skwarek-Maruszewska, Aneta -- Fujiwara, Ikuko -- Hayes, David B -- Rebowski, Grzegorz -- Lappalainen, Pekka -- Pollard, Thomas D -- Dominguez, Roberto -- GM026338/GM/NIGMS NIH HHS/ -- GM073791/GM/NIGMS NIH HHS/ -- HL086655/HL/NHLBI NIH HHS/ -- P01 HL086655/HL/NHLBI NIH HHS/ -- P01 HL086655-01A10004/HL/NHLBI NIH HHS/ -- R01 GM073791/GM/NIGMS NIH HHS/ -- R01 GM073791-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2008 Apr 11;320(5873):239-43. doi: 10.1126/science.1155313.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Boston Biomedical Research Institute, Watertown, MA 02472, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18403713" target="_blank"〉PubMed〈/a〉

    DNA oxidation as triggered by H3K9me2 demethylation drives estrogen-induced gene expression (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-01-12
    Description: Modifications at the N-terminal tails of nucleosomal histones are required for efficient transcription in vivo. We analyzed how H3 histone methylation and demethylation control expression of estrogen-responsive genes and show that a DNA-bound estrogen receptor directs transcription by participating in bending chromatin to contact the RNA polymerase II recruited to the promoter. This process is driven by receptor-targeted demethylation of H3 lysine 9 at both enhancer and promoter sites and is achieved by activation of resident LSD1 demethylase. Localized demethylation produces hydrogen peroxide, which modifies the surrounding DNA and recruits 8-oxoguanine-DNA glycosylase 1 and topoisomeraseIIbeta, triggering chromatin and DNA conformational changes that are essential for estrogen-induced transcription. Our data show a strategy that uses controlled DNA damage and repair to guide productive transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perillo, Bruno -- Ombra, Maria Neve -- Bertoni, Alessandra -- Cuozzo, Concetta -- Sacchetti, Silvana -- Sasso, Annarita -- Chiariotti, Lorenzo -- Malorni, Antonio -- Abbondanza, Ciro -- Avvedimento, Enrico V -- New York, N.Y. -- Science. 2008 Jan 11;319(5860):202-6. doi: 10.1126/science.1147674.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Istituto di Scienze dell'Alimentazione, Consiglio Nazionale delle Ricerche (C.N.R.), 83100 Avellino, Italy. perillo@unina.it〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18187655" target="_blank"〉PubMed〈/a〉

    Maternal alloantigens promote the development of tolerogenic fetal regulatory T cells in utero (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-12-06
    Description: As the immune system develops, T cells are selected or regulated to become tolerant of self antigens and reactive against foreign antigens. In mice, the induction of such tolerance is thought to be attributable to the deletion of self-reactive cells. Here, we show that the human fetal immune system takes advantage of an additional mechanism: the generation of regulatory T cells (Tregs) that suppress fetal immune responses. We find that substantial numbers of maternal cells cross the placenta to reside in fetal lymph nodes, inducing the development of CD4+CD25highFoxP3+ Tregs that suppress fetal antimaternal immunity and persist at least until early adulthood. These findings reveal a form of antigen-specific tolerance in humans, induced in utero and probably active in regulating immune responses after birth.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2648820/" 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/PMC2648820/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mold, Jeff E -- Michaelsson, Jakob -- Burt, Trevor D -- Muench, Marcus O -- Beckerman, Karen P -- Busch, Michael P -- Lee, Tzong-Hae -- Nixon, Douglas F -- McCune, Joseph M -- AI40312/AI/NIAID NIH HHS/ -- AI68498/AI/NIAID NIH HHS/ -- DP1 OD000329/OD/NIH HHS/ -- DP1 OD000329-01/OD/NIH HHS/ -- DP1 OD000329-02/OD/NIH HHS/ -- DP1 OD000329-03/OD/NIH HHS/ -- DP1 OD000329-04/OD/NIH HHS/ -- HD00850/HD/NICHD NIH HHS/ -- HL083388/HL/NHLBI NIH HHS/ -- OD000329/OD/NIH HHS/ -- R01 HL083388/HL/NHLBI NIH HHS/ -- R01 HL083388-02/HL/NHLBI NIH HHS/ -- R37 AI040312/AI/NIAID NIH HHS/ -- R37 AI040312-09/AI/NIAID NIH HHS/ -- R37 AI040312-10/AI/NIAID NIH HHS/ -- R37 AI040312-11/AI/NIAID NIH HHS/ -- R37 AI040312-12/AI/NIAID NIH HHS/ -- R37 AI040312-13/AI/NIAID NIH HHS/ -- RR024131/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2008 Dec 5;322(5907):1562-5. doi: 10.1126/science.1164511.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Experimental Medicine, Department of Medicine, University of California at San Francisco (UCSF), San Francisco, CA 94110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19056990" target="_blank"〉PubMed〈/a〉

    Segregation of axial motor and sensory pathways via heterotypic trans-axonal signaling (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-04-12
    Description: Execution of motor behaviors relies on circuitries effectively integrating immediate sensory feedback to efferent pathways controlling muscle activity. It remains unclear how, during neuromuscular circuit assembly, sensory and motor projections become incorporated into tightly coordinated, yet functionally separate pathways. We report that, within axial nerves, establishment of discrete afferent and efferent pathways depends on coordinate signaling between coextending sensory and motor projections. These heterotypic axon-axon interactions require motor axonal EphA3/EphA4 receptor tyrosine kinases activated by cognate sensory axonal ephrin-A ligands. Genetic elimination of trans-axonal ephrin-A --〉 EphA signaling in mice triggers drastic motor-sensory miswiring, culminating in functional efferents within proximal afferent pathways. Effective assembly of a key circuit underlying motor behaviors thus critically depends on trans-axonal signaling interactions resolving motor and sensory projections into discrete pathways.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3158657/" 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/PMC3158657/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallarda, Benjamin W -- Bonanomi, Dario -- Muller, Daniel -- Brown, Arthur -- Alaynick, William A -- Andrews, Shane E -- Lemke, Greg -- Pfaff, Samuel L -- Marquardt, Till -- NS031249-14A1/NS/NINDS NIH HHS/ -- NS054172-01A2/NS/NINDS NIH HHS/ -- R01 NS054172/NS/NINDS NIH HHS/ -- R01 NS054172-01A2/NS/NINDS NIH HHS/ -- R01 NS054172-02/NS/NINDS NIH HHS/ -- R01 NS054172-03/NS/NINDS NIH HHS/ -- R01 NS054172-04/NS/NINDS NIH HHS/ -- R01 NS054172-05/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2008 Apr 11;320(5873):233-6. doi: 10.1126/science.1153758.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Gene Expression Laboratory, 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/18403711" target="_blank"〉PubMed〈/a〉

    Electric fields due to synaptic currents sharpen excitatory transmission (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-03-29
    Description: The synaptic response waveform, which determines signal integration properties in the brain, depends on the spatiotemporal profile of neurotransmitter in the synaptic cleft. Here, we show that electrophoretic interactions between AMPA receptor-mediated excitatory currents and negatively charged glutamate molecules accelerate the clearance of glutamate from the synaptic cleft, speeding up synaptic responses. This phenomenon is reversed upon depolarization and diminished when intracleft electric fields are weakened through a decrease in the AMPA receptor density. In contrast, the kinetics of receptor-mediated currents evoked by direct application of glutamate are voltage-independent, as are synaptic currents mediated by the electrically neutral neurotransmitter GABA. Voltage-dependent temporal tuning of excitatory synaptic responses may thus contribute to signal integration in neural circuits.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2685065/" 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/PMC2685065/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sylantyev, Sergiy -- Savtchenko, Leonid P -- Niu, Yin-Ping -- Ivanov, Anton I -- Jensen, Thomas P -- Kullmann, Dimitri M -- Xiao, Min-Yi -- Rusakov, Dmitri A -- 071179/Wellcome Trust/United Kingdom -- G0400627/Medical Research Council/United Kingdom -- G0400627(71256)/Medical Research Council/United Kingdom -- G0400627(76527)/Medical Research Council/United Kingdom -- G0600368/Medical Research Council/United Kingdom -- G0600368(77987)/Medical Research Council/United Kingdom -- G116/147/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Mar 28;319(5871):1845-9. doi: 10.1126/science.1154330.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Neurology, University College London, Queen Square, London, WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18369150" target="_blank"〉PubMed〈/a〉

    White fat progenitor cells reside in the adipose vasculature (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-09-20
    Description: White adipose (fat) tissues regulate metabolism, reproduction, and life span. Adipocytes form throughout life, with the most marked expansion of the lineage occurring during the postnatal period. Adipocytes develop in coordination with the vasculature, but the identity and location of white adipocyte progenitor cells in vivo are unknown. We used genetically marked mice to isolate proliferating and renewing adipogenic progenitors. We found that most adipocytes descend from a pool of these proliferating progenitors that are already committed, either prenatally or early in postnatal life. These progenitors reside in the mural cell compartment of the adipose vasculature, but not in the vasculature of other tissues. Thus, the adipose vasculature appears to function as a progenitor niche and may provide signals for adipocyte development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2597101/" 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/PMC2597101/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tang, Wei -- Zeve, Daniel -- Suh, Jae Myoung -- Bosnakovski, Darko -- Kyba, Michael -- Hammer, Robert E -- Tallquist, Michelle D -- Graff, Jonathan M -- 1R01DK064261/DK/NIDDK NIH HHS/ -- 1R01DK066556/DK/NIDDK NIH HHS/ -- R01 DK064261/DK/NIDDK NIH HHS/ -- R01 DK064261-01/DK/NIDDK NIH HHS/ -- R01 DK064261-02/DK/NIDDK NIH HHS/ -- R01 DK064261-03/DK/NIDDK NIH HHS/ -- R01 DK064261-04/DK/NIDDK NIH HHS/ -- R01 DK064261-05/DK/NIDDK NIH HHS/ -- R01 DK066556/DK/NIDDK NIH HHS/ -- R01 DK066556-01/DK/NIDDK NIH HHS/ -- R01 DK066556-02/DK/NIDDK NIH HHS/ -- R01 DK066556-03/DK/NIDDK NIH HHS/ -- R01 DK066556-04/DK/NIDDK NIH HHS/ -- R01 DK066556-05/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2008 Oct 24;322(5901):583-6. doi: 10.1126/science.1156232.

    Description: Pannexin-1 (Px1) is expressed at postsynaptic sites in pyramidal neurons, suggesting that these hemichannels contribute to dendritic signals associated with synaptic function. We found that, in pyramidal neurons, N-methyl-d-aspartate receptor (NMDAR) activation induced a secondary prolonged current and dye flux that were blocked with a specific inhibitory peptide against Px1 hemichannels; knockdown of Px1 by RNA interference blocked the current in cultured neurons. Enhancing endogenous NMDAR activation in brain slices by removing external magnesium ions (Mg2+) triggered epileptiform activity, which had decreased spike amplitude and prolonged interburst interval during application of the Px1 hemichannel blocking peptide. We conclude that Px1 hemichannel opening is triggered by NMDAR stimulation and can contribute to epileptiform seizure activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thompson, Roger J -- Jackson, Michael F -- Olah, Michelle E -- Rungta, Ravi L -- Hines, Dustin J -- Beazely, Michael A -- MacDonald, John F -- MacVicar, Brian A -- New York, N.Y. -- Science. 2008 Dec 5;322(5907):1555-9. doi: 10.1126/science.1165209.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry and Brain Research Centre, University of British Columbia, 2211 Wesbrook Mall, Vancouver, BC V6T 2B5, Canada. rj.thompson@ucalgary.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19056988" target="_blank"〉PubMed〈/a〉

    Proliferating cells express mRNAs with shortened 3' untranslated regions and fewer microRNA target sites (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-06-21
    Description: Messenger RNA (mRNA) stability, localization, and translation are largely determined by sequences in the 3' untranslated region (3'UTR). We found a conserved increase in expression of mRNAs terminating at upstream polyadenylation sites after activation of primary murine CD4+ T lymphocytes. This program, resulting in shorter 3'UTRs, is a characteristic of gene expression during immune cell activation and correlates with proliferation across diverse cell types and tissues. Forced expression of full-length 3'UTRs conferred reduced protein expression. In some cases the reduction in protein expression could be reversed by deletion of predicted microRNA target sites in the variably included region. Our data indicate that gene expression is coordinately regulated, such that states of increased proliferation are associated with widespread reductions in the 3'UTR-based regulatory capacity of mRNAs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2587246/" 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/PMC2587246/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sandberg, Rickard -- Neilson, Joel R -- Sarma, Arup -- Sharp, Phillip A -- Burge, Christopher B -- P01 CA042063/CA/NCI NIH HHS/ -- P01 CA042063-22/CA/NCI NIH HHS/ -- P01-CA42063/CA/NCI NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- R01 GM034277/GM/NIGMS NIH HHS/ -- R01 GM034277-23/GM/NIGMS NIH HHS/ -- R01 HG002439/HG/NHGRI NIH HHS/ -- R01 HG002439-07/HG/NHGRI NIH HHS/ -- R01-GM34277/GM/NIGMS NIH HHS/ -- R01-HG002439/HG/NHGRI NIH HHS/ -- U19 AI056900/AI/NIAID NIH HHS/ -- U19 AI056900-010001/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2008 Jun 20;320(5883):1643-7. doi: 10.1126/science.1155390.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18566288" target="_blank"〉PubMed〈/a〉

    Human fetal hemoglobin expression is regulated by the developmental stage-specific repressor BCL11A (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-12-06
    Description: Differences in the amount of fetal hemoglobin (HbF) that persists into adulthood affect the severity of sickle cell disease and the beta-thalassemia syndromes. Genetic association studies have identified sequence variants in the gene BCL11A that influence HbF levels. Here, we examine BCL11A as a potential regulator of HbF expression. The high-HbF BCL11A genotype is associated with reduced BCL11A expression. Moreover, abundant expression of full-length forms of BCL11A is developmentally restricted to adult erythroid cells. Down-regulation of BCL11A expression in primary adult erythroid cells leads to robust HbF expression. Consistent with a direct role of BCL11A in globin gene regulation, we find that BCL11A occupies several discrete sites in the beta-globin gene cluster. BCL11A emerges as a therapeutic target for reactivation of HbF in beta-hemoglobin disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sankaran, Vijay G -- Menne, Tobias F -- Xu, Jian -- Akie, Thomas E -- Lettre, Guillaume -- Van Handel, Ben -- Mikkola, Hanna K A -- Hirschhorn, Joel N -- Cantor, Alan B -- Orkin, Stuart H -- HL32259-27/HL/NHLBI NIH HHS/ -- HL32262-26/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Dec 19;322(5909):1839-42. doi: 10.1126/science.1165409.

    Autophagy is essential for preimplantation development of mouse embryos (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-07-05
    Description: After fertilization, maternal proteins in oocytes are degraded and new proteins encoded by the zygotic genome are synthesized. We found that autophagy, a process for the degradation of cytoplasmic constituents in the lysosome, plays a critical role during this period. Autophagy was triggered by fertilization and up-regulated in early mouse embryos. Autophagy-defective oocytes derived from oocyte-specific Atg5 (autophagy-related 5) knockout mice failed to develop beyond the four- and eight-cell stages if they were fertilized by Atg5-null sperm, but could develop if they were fertilized by wild-type sperm. Protein synthesis rates were reduced in the autophagy-null embryos. Thus, autophagic degradation within early embryos is essential for preimplantation development in mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsukamoto, Satoshi -- Kuma, Akiko -- Murakami, Mirei -- Kishi, Chieko -- Yamamoto, Akitsugu -- Mizushima, Noboru -- New York, N.Y. -- Science. 2008 Jul 4;321(5885):117-20. doi: 10.1126/science.1154822.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology and Cell Biology, Tokyo Medical and Dental University, 1-5-45 Yushima, Bunkyo-ku, Tokyo 113-8519, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18599786" target="_blank"〉PubMed〈/a〉

    TMEM16A, a membrane protein associated with calcium-dependent chloride channel activity (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-09-06
    Description: Calcium-dependent chloride channels are required for normal electrolyte and fluid secretion, olfactory perception, and neuronal and smooth muscle excitability. The molecular identity of these membrane proteins is still unclear. Treatment of bronchial epithelial cells with interleukin-4 (IL-4) causes increased calcium-dependent chloride channel activity, presumably by regulating expression of the corresponding genes. We performed a global gene expression analysis to identify membrane proteins that are regulated by IL-4. Transfection of epithelial cells with specific small interfering RNA against each of these proteins shows that TMEM16A, a member of a family of putative plasma membrane proteins with unknown function, is associated with calcium-dependent chloride current, as measured with halide-sensitive fluorescent proteins, short-circuit current, and patch-clamp techniques. Our results indicate that TMEM16A is an intrinsic constituent of the calcium-dependent chloride channel. Identification of a previously unknown family of membrane proteins associated with chloride channel function will improve our understanding of chloride transport physiopathology and allow for the development of pharmacological tools useful for basic research and drug development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Caputo, Antonella -- Caci, Emanuela -- Ferrera, Loretta -- Pedemonte, Nicoletta -- Barsanti, Cristina -- Sondo, Elvira -- Pfeffer, Ulrich -- Ravazzolo, Roberto -- Zegarra-Moran, Olga -- Galietta, Luis J V -- GGP05103/Telethon/Italy -- New York, N.Y. -- Science. 2008 Oct 24;322(5901):590-4. doi: 10.1126/science.1163518.

    Surface mobility of postsynaptic AMPARs tunes synaptic transmission (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-04-12
    Description: AMPA glutamate receptors (AMPARs) mediate fast excitatory synaptic transmission. Upon fast consecutive synaptic stimulation, transmission can be depressed. Recuperation from fast synaptic depression has been attributed solely to recovery of transmitter release and/or AMPAR desensitization. We show that AMPAR lateral diffusion, observed in both intact hippocampi and cultured neurons, allows fast exchange of desensitized receptors with naive functional ones within or near the postsynaptic density. Recovery from depression in the tens of millisecond time range can be explained in part by this fast receptor exchange. Preventing AMPAR surface movements through cross-linking, endogenous clustering, or calcium rise all slow recovery from depression. Physiological regulation of postsynaptic receptor mobility affects the fidelity of synaptic transmission by shaping the frequency dependence of synaptic responses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2715948/" 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/PMC2715948/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heine, Martin -- Groc, Laurent -- Frischknecht, Renato -- Beique, Jean-Claude -- Lounis, Brahim -- Rumbaugh, Gavin -- Huganir, Richard L -- Cognet, Laurent -- Choquet, Daniel -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Apr 11;320(5873):201-5. doi: 10.1126/science.1152089.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CNRS, UMR 5091, Universite Bordeaux, Bordeaux, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18403705" target="_blank"〉PubMed〈/a〉

    Description: The development of individual organs in animal embryos involves the formation of tissue-specific stem cells that sustain cell renewal of their own tissue for the lifetime of the organism. Although details of their origin are not always known, tissue-specific stem cells usually share the expression of key transcription factors with cells of the embryonic rudiment from which they arise, and are probably in a similar developmental state. On the other hand, the isolation of pluripotent stem cells from the postnatal organism has encouraged the formulation of models of embryonic and postnatal development that are at variance with the conventional ones. Possible explanations for the existence of such cells, and the issue of whether they also exist in vivo, are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slack, J M W -- G0300415/Medical Research Council/United Kingdom -- G0500220/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2008 Dec 5;322(5907):1498-501. doi: 10.1126/science.1162782.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stem Cell Institute, University of Minnesota, McGuire Translational Research Facility, 2001 6th Street SE, Minneapolis, MN 55455, USA. slack017@umn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19056975" target="_blank"〉PubMed〈/a〉

    PirB is a functional receptor for myelin inhibitors of axonal regeneration (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-11-08
    Description: A major barrier to regenerating axons after injury in the mammalian central nervous system is an unfavorable milieu. Three proteins found in myelin--Nogo, MAG, and OMgp--inhibit axon regeneration in vitro and bind to the glycosylphosphatidylinositol-anchored Nogo receptor (NgR). However, genetic deletion of NgR has only a modest disinhibitory effect, suggesting that other binding receptors for these molecules probably exist. With the use of expression cloning, we have found that paired immunoglobulin-like receptor B (PirB), which has been implicated in nervous system plasticity, is a high-affinity receptor for Nogo, MAG, and OMgp. Interfering with PirB activity, either with antibodies or genetically, partially rescues neurite inhibition by Nogo66, MAG, OMgp, and myelin in cultured neurons. Blocking both PirB and NgR activities leads to near-complete release from myelin inhibition. Our results implicate PirB in mediating regeneration block, identify PirB as a potential target for axon regeneration therapies, and provide an explanation for the similar enhancements of visual system plasticity in PirB and NgR knockout mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Atwal, Jasvinder K -- Pinkston-Gosse, Julie -- Syken, Josh -- Stawicki, Scott -- Wu, Yan -- Shatz, Carla -- Tessier-Lavigne, Marc -- New York, N.Y. -- Science. 2008 Nov 7;322(5903):967-70. doi: 10.1126/science.1161151.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurodegeneration Labs and Research Drug Discovery, Genentech, 1 DNA Way, South San Francisco, CA 94080, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18988857" target="_blank"〉PubMed〈/a〉

    Variability and robustness in T cell activation from regulated heterogeneity in protein levels (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-08-23
    Description: In T cells, the stochasticity of protein expression could contribute to the useful diversification of biological functions within a clonal population or interfere with accurate antigen discrimination. Combining computer modeling and single-cell measurements, we examined how endogenous variation in the expression levels of signaling proteins might affect antigen responsiveness during T cell activation. We found that the CD8 co-receptor fine-tunes activation thresholds, whereas the soluble hematopoietic phosphatase 1 (SHP-1) digitally regulates cell responsiveness. Stochastic variation in the expression of these proteins generates substantial diversity of activation within a clonal population of T cells, but co-regulation of CD8 and SHP-1 levels ultimately limits this very diversity. These findings reveal how eukaryotic cells can draw on regulated variation in gene expression to achieve phenotypic variability in a controlled manner.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2673522/" 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/PMC2673522/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feinerman, Ofer -- Veiga, Joel -- Dorfman, Jeffrey R -- Germain, Ronald N -- Altan-Bonnet, Gregoire -- Z01 AI000403-24/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Aug 22;321(5892):1081-4. doi: 10.1126/science.1158013.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉ImmunoDynamics Group, Program in Computational Biology and Immunology, Memorial Sloan-Kettering Cancer Center, 1275 York Avenue, Box 460, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18719282" target="_blank"〉PubMed〈/a〉

    NFAT binding and regulation of T cell activation by the cytoplasmic scaffolding Homer proteins (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-01-26
    Description: T cell receptor (TCR) and costimulatory receptor (CD28) signals cooperate in activating T cells, although understanding of how these pathways are themselves regulated is incomplete. We found that Homer2 and Homer3, members of the Homer family of cytoplasmic scaffolding proteins, are negative regulators of T cell activation. This is achieved through binding of nuclear factor of activated T cells (NFAT) and by competing with calcineurin. Homer-NFAT binding was also antagonized by active serine-threonine kinase AKT, thereby enhancing TCR signaling via calcineurin-dependent dephosphorylation of NFAT. This corresponded with changes in cytokine expression and an increase in effector-memory T cell populations in Homer-deficient mice, which also developed autoimmune-like pathology. These results demonstrate a further means by which costimulatory signals are regulated to control self-reactivity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3602998/" 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/PMC3602998/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Guo N -- Huso, David L -- Bouyain, Samuel -- Tu, Jianchen -- McCorkell, Kelly A -- May, Michael J -- Zhu, Yuwen -- Lutz, Michael -- Collins, Samuel -- Dehoff, Marlin -- Kang, Shin -- Whartenby, Katharine -- Powell, Jonathan -- Leahy, Daniel -- Worley, Paul F -- DA00266/DA/NIDA NIH HHS/ -- DA10309/DA/NIDA NIH HHS/ -- P30 CA006973/CA/NCI NIH HHS/ -- R01 CA098109/CA/NCI NIH HHS/ -- T32 CA009140/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 Jan 25;319(5862):476-81. doi: 10.1126/science.1151227.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Biochemistry, Cellular and Molecular Biology, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18218901" target="_blank"〉PubMed〈/a〉

    Video-rate far-field optical nanoscopy dissects synaptic vesicle movement (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-02-23
    Description: We present video-rate (28 frames per second) far-field optical imaging with a focal spot size of 62 nanometers in living cells. Fluorescently labeled synaptic vesicles inside the axons of cultured neurons were recorded with stimulated emission depletion (STED) microscopy in a 2.5-micrometer by 1.8-micrometer field of view. By reducing the cross-sectional area of the focal spot by about a factor of 18 below the diffraction limit (260 nanometers), STED allowed us to map and describe the vesicle mobility within the highly confined space of synaptic boutons. Although restricted within boutons, the vesicle movement was substantially faster in nonbouton areas, consistent with the observation that a sizable vesicle pool continuously transits through the axons. Our study demonstrates the emerging ability of optical microscopy to investigate intracellular physiological processes on the nanoscale in real time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Westphal, Volker -- Rizzoli, Silvio O -- Lauterbach, Marcel A -- Kamin, Dirk -- Jahn, Reinhard -- Hell, Stefan W -- New York, N.Y. -- Science. 2008 Apr 11;320(5873):246-9. doi: 10.1126/science.1154228.

    Description: We have assembled a proteome map for Arabidopsis thaliana from high-density, organ-specific proteome catalogs that we generated for different organs, developmental stages, and undifferentiated cultured cells. We matched 86,456 unique peptides to 13,029 proteins and provide expression evidence for 57 gene models that are not represented in the TAIR7 protein database. Analysis of the proteome identified organ-specific biomarkers and allowed us to compile an organ-specific set of proteotypic peptides for 4105 proteins to facilitate targeted quantitative proteomics surveys. Quantitative information for the identified proteins was used to establish correlations between transcript and protein accumulation in different plant organs. The Arabidopsis proteome map provides information about genome activity and proteome assembly and is available as a resource for plant systems biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baerenfaller, Katja -- Grossmann, Jonas -- Grobei, Monica A -- Hull, Roger -- Hirsch-Hoffmann, Matthias -- Yalovsky, Shaul -- Zimmermann, Philip -- Grossniklaus, Ueli -- Gruissem, Wilhelm -- Baginsky, Sacha -- New York, N.Y. -- Science. 2008 May 16;320(5878):938-41. doi: 10.1126/science.1157956.

    Noncytotoxic lytic granule-mediated CD8+ T cell inhibition of HSV-1 reactivation from neuronal latency (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-10-11
    Description: Reactivation of herpes simplex virus type 1 (HSV-1) from neuronal latency is a common and potentially devastating cause of disease worldwide. CD8+ T cells can completely inhibit HSV reactivation in mice, with interferon-gamma affording a portion of this protection. We found that CD8+ T cell lytic granules are also required for the maintenance of neuronal latency both in vivo and in ex vivo ganglia cultures and that their directed release to the junction with neurons in latently infected ganglia did not induce neuronal apoptosis. Here, we describe a nonlethal mechanism of viral inactivation in which the lytic granule component, granzyme B, degrades the HSV-1 immediate early protein, ICP4, which is essential for further viral gene expression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2680315/" 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/PMC2680315/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knickelbein, Jared E -- Khanna, Kamal M -- Yee, Michael B -- Baty, Catherine J -- Kinchington, Paul R -- Hendricks, Robert L -- F30 NS061471-01/NS/NINDS NIH HHS/ -- F30NS061471/NS/NINDS NIH HHS/ -- P30EY08098/EY/NEI NIH HHS/ -- R01EY015291/EY/NEI NIH HHS/ -- R01EY05945/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2008 Oct 10;322(5899):268-71. doi: 10.1126/science.1164164.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Program in Immunology, University of Pittsburgh School of Medicine, Pittsburgh, PA 15213, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18845757" target="_blank"〉PubMed〈/a〉

    Activation of the cellular DNA damage response in the absence of DNA lesions (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-05-17
    Description: The cellular DNA damage response (DDR) is initiated by the rapid recruitment of repair factors to the site of DNA damage to form a multiprotein repair complex. How the repair complex senses damaged DNA and then activates the DDR is not well understood. We show that prolonged binding of DNA repair factors to chromatin can elicit the DDR in an ATM (ataxia telangiectasia mutated)- and DNAPK (DNA-dependent protein kinase)-dependent manner in the absence of DNA damage. Targeting of single repair factors to chromatin revealed a hierarchy of protein interactions within the repair complex and suggests amplification of the damage signal. We conclude that activation of the DDR does not require DNA damage and stable association of repair factors with chromatin is likely a critical step in triggering, amplifying, and maintaining the DDR signal.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2575099/" 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/PMC2575099/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Soutoglou, Evi -- Misteli, Tom -- Z01 BC010309-09/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Jun 13;320(5882):1507-10. doi: 10.1126/science.1159051.

    Activation of FOXO1 by Cdk1 in cycling cells and postmitotic neurons (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-03-22
    Description: Activation of cyclin-dependent kinase 1 (Cdk1) has been linked to cell death of postmitotic neurons in brain development and disease. We found that Cdk1 phosphorylated the transcription factor FOXO1 at Ser249 in vitro and in vivo. The phosphorylation of FOXO1 at Ser249 disrupted FOXO1 binding with 14-3-3 proteins and thereby promoted the nuclear accumulation of FOXO1 and stimulated FOXO1-dependent transcription, leading to cell death in neurons. In proliferating cells, Cdk1 induced FOXO1 Ser249 phosphorylation at the G2/M phase of the cell cycle, resulting in FOXO1-dependent expression of the mitotic regulator Polo-like kinase (Plk). These findings define a conserved signaling link between Cdk1 and FOXO1 that may have a key role in diverse biological processes, including the degeneration of postmitotic neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yuan, Zengqiang -- Becker, Esther B E -- Merlo, Paola -- Yamada, Tomoko -- DiBacco, Sara -- Konishi, Yoshiyuki -- Schaefer, Erik M -- Bonni, Azad -- NS047188/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2008 Mar 21;319(5870):1665-8. doi: 10.1126/science.1152337.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Harvard Medical School, 77 Avenue Louis Pasteur, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18356527" target="_blank"〉PubMed〈/a〉

    Rapid membrane disruption by a perforin-like protein facilitates parasite exit from host cells (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-12-20
    Description: Perforin-like proteins are expressed by many bacterial and protozoan pathogens, yet little is known about their function or mode of action. Here, we describe Toxoplasma perforin-like protein 1 (TgPLP1), a secreted perforin-like protein of the intracellular protozoan pathogen Toxoplasma gondii that displays structural features necessary for pore formation. After intracellular growth, TgPLP1-deficient parasites failed to exit normally, resulting in entrapment within host cells. We show that this defect is due to an inability to rapidly permeabilize the parasitophorous vacuole membrane and host plasma membrane during exit. TgPLP1 ablation had little effect on growth in culture but resulted in a reduction greater than five orders of magnitude of acute virulence in mice. Perforin-like proteins from other intracellular pathogens may play a similar role in microbial egress and virulence.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2662845/" 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/PMC2662845/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kafsack, Bjorn F C -- Pena, Janethe D O -- Coppens, Isabelle -- Ravindran, Sandeep -- Boothroyd, John C -- Carruthers, Vern B -- R01 AI021423/AI/NIAID NIH HHS/ -- R01 AI046675/AI/NIAID NIH HHS/ -- R01 AI046675-06/AI/NIAID NIH HHS/ -- R01 AI046675-07/AI/NIAID NIH HHS/ -- R01 AI046675-08/AI/NIAID NIH HHS/ -- R01 AI046675-09/AI/NIAID NIH HHS/ -- R01 AI46675/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2009 Jan 23;323(5913):530-3. doi: 10.1126/science.1165740.

    Description: Human malignant cancer tumors grafted into nude mice produce tumors containing both human cancer cells and the host's stromal cells. After short-term propagation of these tumors in vitro, the murine mesenchymal cells appear transformed and are tumorigenic in nude mice. However, established human cancer cell lines fail to similarly after adjacent murine stromal cells when used to produce tumors in nude mice. These experiments suggest that cancer cells may recruit normal cells to become malignant, qualifying the view of the clonal (unicellular) origin of cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldenberg, D M -- Pavia, R A -- 1R01 CA17198/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Apr 3;212(4490):65-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209521" target="_blank"〉PubMed〈/a〉

    Voltage clamp studies in macrophages from mouse spleen cultures (1981)

    Details
    Publication Date: 1981-10-23
    Description: Voltage clamp studies of macrophages from cultures of mouse spleen macrophages produced N-shaped steady-state current-voltage curves containing a region of negative slope resistance. Some macrophages exhibit two stable states of membrane potential, having current-voltage relationships that cross the voltage axis at three points. Outward currents that turn on at voltages of +15 millivolts or greater were noted in several cells. The addition of barium chloride to the bathing medium abolished the negative slope resistance and reduced the inward currents in response to hyperpolarizing voltage steps. These data provide direct evidence that macrophages exhibit at least tow different voltage-dependent conductances and demonstrate that voltage clamp techniques can be useful in studying the membrane properties of leukocytes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallin, E K -- New York, N.Y. -- Science. 1981 Oct 23;214(4519):458-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7291986" target="_blank"〉PubMed〈/a〉

    Multiple opiate receptors: alcohol selectively inhibits binding to delta receptors (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-10-23
    Description: The addition of ethanol or other aliphatic alcohols to rat brain membranes strongly inhibits binding of enkephalins at concentrations at which little inhibition of opiate alkaloids is seen. Inhibition is reversible, and potency increases with chain length of the alcohol. The results suggest that delta receptors are considerably more sensitive to alcohols than mu receptors. This is the first demonstration of selective inhibition of one of the postulated classes of opiate receptors by a reagent that is not a ligand for the receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hiller, J M -- Angel, L M -- Simon, E J -- DA-00017/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 23;214(4519):468-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6270788" target="_blank"〉PubMed〈/a〉

    Divalent cation ionophores stimulate resorption and inhibit DNA synthesis in cultured fetal rat bone (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-06-05
    Description: Two divalent cation ionophores, A23187 and Ionomycin, which are selective for calcium, stimulated the resorption of fetal rat long bones in organ culture at 0.1 to 1 micromolar but not at higher concentrations. Both agents inhibited DNA synthesis at concentrations that stimulated resorption. These results might explain the differences in ionophore effects on bone previously reported, and they imply that cell replication is not required for osteoclast formation in fetal rat long bone cultures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lorenzo, J A -- Raisz, L G -- AM 07290/AM/NIADDK NIH HHS/ -- AM 18063/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 5;212(4499):1157-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6785885" target="_blank"〉PubMed〈/a〉

    Hormonal requirements for growth of arterial smooth muscle cells in vitro: and endocrine approach to atherosclerosis (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-05-15
    Description: In this study the hormonal requirements for the growth of arterial smooth muscle cells in vitro were determined. A serum-free, biochemically defined medium, supplemented with the relevant hormones, permitted proliferation and propagation of normal diploid mammalian arterial smooth muscle cells. Serum-free, hormone-supplemented cultures spontaneously formed atherosclerotic plaque-like nodules. Thus atherosclerosis may be mediated by a complex endocrine system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weinstein, R -- Stemerman, M B -- Maciag, T -- AM 07026/AM/NIADDK NIH HHS/ -- HL 06197/HL/NHLBI NIH HHS/ -- HL 07374/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1981 May 15;212(4496):818-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7013068" target="_blank"〉PubMed〈/a〉

    Homeostasis of the antibody response: immunoregulation by NK cells (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-11-11
    Description: When injected into mice, the synthetic double-stranded polynucleotide poly(inosinic) X poly(cytidylic) acid induces high natural killer (NK) cell activity within 4 to 12 hours. Induction of NK activity in mice immunized 2 or 3 days previously, or the addition of NK cells to cultures immunized in vitro 2 or 3 days previously, promotes early termination of the ongoing primary immunoglobulin M antibody response. A target for NK cells is a population of accessory cells that has interacted with antigen and is necessary for sustaining the antibody response. The inference is strong that NK cells induced normally by immunization also terminate the usual antibody response in vivo by elimination of antigen-exposed accessory cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abruzzo, L V -- Rowley, D A -- 5-T32-CA-09267/CA/NCI NIH HHS/ -- R01-10242/PHS HHS/ -- New York, N.Y. -- Science. 1983 Nov 11;222(4624):581-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6685343" target="_blank"〉PubMed〈/a〉

    Description: The human parasite Trypanosoma brucei gambiense grew continuously at 37 degrees C in primary cultures of murine bone marrow. Cultured parasites remained virulent for mice. Rapid parasite growth coincided with the appearance of adherent adipocyte-epitheloid cell aggregates that also promoted hematopoiesis.

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-03-18
    Description: Immunohistochemical techniques were used to confirm biochemical evidence that parenchymal cells isolated from adult rat liver and maintained in nonreplicating monolayer culture for 2 days synthesized type IV basement membrane collagen. On continued incubation in serum-free medium, the hepatocytes also synthesized the interstitial collagens, types I and III. Consistent with these results in culture, type IV collagen was localized to the hepatocytes in slices of pathologic rat liver. Hence collagen formation is a previously unrecognized function of the hepatocyte that may be important in the pathogenesis of liver fibrosis or cirrhosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diegelmann, R F -- Guzelian, P S -- Gay, R -- Gay, S -- AM18976/AM/NIADDK NIH HHS/ -- DE02570/DE/NIDCR NIH HHS/ -- HL11310/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Mar 18;219(4590):1343-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828863" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1983-12-09
    Description: Nonmalignant diploid human fibroblast cells (GM3498B) derived from a skin biopsy of a patient with Bloom's syndrome have been transformed by transfection with DNA from a tumorigenic mouse cell line (Ha-8) carrying a single copy of the Harvey murine sarcoma virus (Ha-MuSV) genome. The transformed cell lines have an extended life-span, form colonies in agarose, and proliferate in nude mice--characteristics of neoplastic transformation. Like the parental cells, they also exhibit a high spontaneous level of sister chromatid exchanges. Finally, the transformed cells contain most, if not all, of the Ha-MuSV genome as well as the human rasH sequence. These experiments show that these diploid nonmalignant human cells can be used as recipients in transfection experiments for studying the genetic control of neoplastic transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doniger, J -- Di Paolo, J A -- Popescu, N C -- New York, N.Y. -- Science. 1983 Dec 9;222(4628):1144-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6648529" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1983-04-08
    Description: Cultured bronchial epithelial and fibroblastic cells from humans were used to study DNA damage and toxicity caused by formaldehyde. Formaldehyde caused the formation of cross-links between DNA and proteins, caused single-strand breaks in DNA, and inhibited the resealing of single-strand breaks produced by ionizing radiation. Formaldehyde also inhibited the unscheduled DNA synthesis that occurs after exposure of cells to ultraviolet irradiation or to benzo[a]pyrene diolexpoxide but at doses substantially higher than those required to inhibit the resealing of x-ray-induced single-strand breaks. Therefore, formaldehyde could exert its mutagenic and carcinogenic effects by both damaging DNA and inhibiting DNA repair.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grafstrom, R C -- Fornace, A J Jr -- Autrup, H -- Lechner, J F -- Harris, C C -- New York, N.Y. -- Science. 1983 Apr 8;220(4593):216-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828890" target="_blank"〉PubMed〈/a〉

    Publication Date: 1983-10-07
    Description: Suspensions of embryonic chick neuronal cells adhered to monolayers of glial cells, but few neurons bound to control monolayers of fibroblastic cells from meninges or skin. Neuronal cell-glial cell adhesion was inhibited by prior incubation of the neurons with Fab' fragments of antibodies to neuronal membranes. In contrast, antibodies to the neural cell adhesion molecule (N-CAM) did not inhibit the binding. These results suggest that a specific adhesive mechanism between neurons and glial cells exists and that it is mediated by CAM's that differ from those so far identified.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grumet, M -- Rutishauser, U -- Edelman, G M -- AI-11378/AI/NIAID NIH HHS/ -- HD-09635/HD/NICHD NIH HHS/ -- HD-16550/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1983 Oct 7;222(4619):60-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6194561" target="_blank"〉PubMed〈/a〉

    Publication Date: 1983-09-23
    Description: When cultured in a hypoxic environment similar to that found in the center of a wound, macrophages secreted active angiogenesis factor into the medium. Under conditions similar to those of well-oxygenated tissue, macrophages did not secrete active angiogenesis factor. Macrophages that secreted the factor at hypoxic conditions stopped secreting it when returned to room air. Thus the control of angiogenesis in wound healing may be the result of macrophages responding to tissue oxygen tension without the necessity of interacting with other cell types or biochemical signals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knighton, D R -- Hunt, T K -- Scheuenstuhl, H -- Halliday, B J -- Werb, Z -- Banda, M J -- GM27345/GM/NIGMS NIH HHS/ -- HL26323/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1983 Sep 23;221(4617):1283-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6612342" target="_blank"〉PubMed〈/a〉

    Description: The distribution of keratin intermediate filaments, previously considered static in organization and imperturbable by conventional drugs used to alter the structure and organization of the cytoskeleton, can be altered significantly by treatment with colchicine and cytochalasin D. The loss of microfilaments and microtubules converts the keratin cytoskeleton from a branching, even distribution to a series of starlike structures whose filaments are maintained by multiple membrane attachment sites. These findings provide a means for manipulating cytokeratin organization to investigate the role of keratins in cytoskeletal structure and function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knapp, L W -- O'Guin, W M -- Sawyer, R H -- New York, N.Y. -- Science. 1983 Feb 4;219(4584):501-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6186022" target="_blank"〉PubMed〈/a〉

The membrane remnants of myotubes ruptured by osmotic shock also supported the responsiveness of the cultured neurons to transmitter, whereas muscle-conditioned medium or membrane remnants of nonmuscle embryonic skin cells did not support this responsiveness. The regulation of chemosensitivity by contact of neurons with the target cell membrane may be important in the formation and maintenance of neuronal circuitry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tuttle, J B -- NS-10338/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1983 May 27;220(4600):977-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6133352" target="_blank"〉PubMed〈/a〉

    High-frequency transfection and cytopathology of the hepatitis B virus core antigen gene in human cells (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-10-28
    Description: A protoplast fusion method was developed to stably transfect human cells with pSV2-derived plasmids at frequencies greater than 10(-3). This procedure made it possible to test the biological effect of a hepatitis B virus (HBV) gene independent of the viral structures required for infection. A pSV2gpt+ plasmid constructed to carry a subgenomic fragment of HBV that contained the core antigen gene (HBc gene) was transfected into human cells. A human epithelial cell line was stably transfected with the HBc+ gene by selecting recipient cells for expression of guanine phosphoribosyl transferase expression. With this gpt+/HBc+ cell line it was shown that growth in serum-free medium or treatment with 5'-azacytidine stimulates the production of the HBV core antigen. A hepatocellular carcinoma carrying the entire HBV genome was stimulated to produce the HBc gene product in response to the same factors that stimulated HBcAg production in the gpt+/HBc+ cell line constructed by transfection. The temporal relation between the cytopathologic response and HBc gene expression was similar for both cell types, indicating a primary role for HBc gene expression in the cytopathology of HBV-infected human liver.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoakum, G H -- Korba, B E -- Lechner, J F -- Tokiwa, T -- Gazdar, A F -- Seeley, T -- Siegel, M -- Leeman, L -- Autrup, H -- Harris, C C -- New York, N.Y. -- Science. 1983 Oct 28;222(4622):385-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6194563" target="_blank"〉PubMed〈/a〉

    Description: Highly purified preparations of insulin receptor catalyzed the phosphorylation of the 95,000-dalton subunit of the insulin receptor. This subunit of the insulin receptor was also labeled with [alpha-32P]8-azidoadenosine 5'-triphosphate, a photoaffinity label for adenosine triphosphate binding sites. The identity of the 95,000-dalton band was confirmed in both cases by precipitation with a monoclonal antibody to the insulin receptor. These results suggest that the insulin receptor is itself a protein kinase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roth, R A -- Cassell, D J -- New York, N.Y. -- Science. 1983 Jan 21;219(4582):299-301.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6849137" target="_blank"〉PubMed〈/a〉

    Description: Cultured hippocampal neurons, when exposed to cyanide or an anoxic atmosphere in the early stages of differentiation, were not visibly affected. However, neurons in the mature cultures died when exposed to cyanide or anoxia. Cell death could be prevented by treatment with magnesium, which eliminates synaptic activity. These observations suggest that damage in hypoxic neurons is mediated by synaptic activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rothman, S M -- 5 K07 N500568-02/PHS HHS/ -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):536-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6836300" target="_blank"〉PubMed〈/a〉

    Infection of normal human epithelial cells by Epstein-Barr virus (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-03-11
    Description: Primary cultures of epithelial cells were grown from the tonsils and adenoids of patients with diseases not related to Epstein-Barr virus. The cells could not be infected by Epstein-Barr virus. Fluorescein-labeled Epstein-Barr virus and a cytofluorograph were then used to show that the epithelial cells do not have detectable receptors for the virus. However, implantation with Epstein-Barr virus receptors gave the cells the ability to bind the labeled virus. One to 5 percent of receptor-implanted cells exposed to the transforming B95-8 substrain of the virus expressed Epstein-Barr nuclear antigen. The early and viral capsid Epstein-Barr virus-determined antigens were not detected in the virus-infected cultures. The results show that normal human epithelial cells from the nasopharynx become susceptible to infection by Epstein-Barr virus when the membrane barrier resulting from the lack of viral receptors is overcome by receptor implantation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shapiro, I M -- Volsky, D J -- 1R01 CA33386-01/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 Mar 11;219(4589):1225-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6298935" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1983-09-23
    Description: Changes occur in the synthesis and axonal transport of neuronal proteins in dorsal-root ganglia axons as a result of contact with cells from the spinal cord during synapse formation. Dorsal-root ganglia cells were cultured in a compartmental cel culture system that allows separate access to neuronal cell bodies and their axons. When cells from the ventral spinal cord were cultured with the dorsal-root ganglia axons, synapses were established within a few days. Metabolic labeling and two-dimensional electrophoresis revealed that four of more than 300 axonal proteins had changed in their expression by the time synapses were established. The highly selective nature of these changes suggests that the proteins involved may be important in the processes of axon growth and synapse formation and their regulation by the regional environment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sonderegger, P -- Fishman, M C -- Bokoum, M -- Bauer, H C -- Nelson, P G -- New York, N.Y. -- Science. 1983 Sep 23;221(4617):1294-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6612344" target="_blank"〉PubMed〈/a〉

    Description: Two toxins, latrunculins A and B, which contain a new class of 16- and 14-membered marine macrolides attached to the rare 2-thiazolidinone moiety, were purified recently from the Red Sea sponge Latrunculia magnifica. The effects of these toxins on cultured mouse neuroblastoma and fibroblast cells have been evaluated. In both types of cells, submicromolar toxin concentrations rapidly induce striking changes in cell morphology that are reversible upon removal of the toxin. Immunofluorescence studies with antibodies specific for cytoskeletal proteins reveal that the toxins cause major alterations in the organization of microfilaments without obvious effects on the organization of the microtubular system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spector, I -- Shochet, N R -- Kashman, Y -- Groweiss, A -- New York, N.Y. -- Science. 1983 Feb 4;219(4584):493-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6681676" target="_blank"〉PubMed〈/a〉

At 0.7 X 10(-7) to 1.5 X 10(-7) M and at 4 X 10(-7) M amanitin equivalents, the conjugate inhibited protein synthesis in S49.1 cells by 50 percent and 80 to 96 percent, respectively. At these concentrations, mutant Thy l-deficient S49 cells and other murine lymphoma lacking Thy l altogether or carrying Thy 1.1 antigens were unaffected.

    Lateral diffusion of surface molecules in animal cells and tissues (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-08-21
    Description: When bound to cell surfaces, certain lectins such as concanavalin A induce a drop in the average diffusion coefficients (D) of a number of cell surface molecules. To find whether such anchorage modulation occurs naturally, D of surface antigens on different cell and tissue types were measured by fluorescence photobleaching recovery. Values for cells of the same tissue origin under different conditions of growth and association - in tissues, in small aggregates, and as isolated cells - varied by less than twofold when polyspecific monovalent antibodies to cell surface antigens were used, a range much less than the sixfold decrease in D observed after lectin-induced anchorage modulation. Thus, if reversible modulation of the diffusion rate is used naturally as a means of cell signaling, it must involve only a few kinds of surface receptors not detected by the antibodies used in this study. In certain tissues, however, a significant proportion of cells showed no apparent receptor mobility. This "all or none" modulation of lateral diffusion may reflect relatively long-lasting alterations in the states of a single cell type or differentiation among the cells of the particular tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gall, W E -- Edelman, G M -- AI-09273/AI/NIAID NIH HHS/ -- AI-11378/AI/NIAID NIH HHS/ -- AM-04256/AM/NIADDK NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1981 Aug 21;213(4510):903-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7196087" target="_blank"〉PubMed〈/a〉

    Description: Kirsten sarcoma virus produced a low incidence of transient morphological transformation in primary cultures of rat ovarian granulosa cells. In the presence of epidermal growth factor, the incidence of transient transformation increased severalfold and two continuous cell lines were established. Epidermal growth factor, a naturally occurring polypeptide hormone, appears to act here as a tumor promoter in the retrovirus-induced transformation of a mesodermally derived epithelium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harrison, J -- Auersperg, N -- New York, N.Y. -- Science. 1981 Jul 10;213(4504):218-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6264597" target="_blank"〉PubMed〈/a〉

    Somatomedin B: mitogenic activity derived from contaminant epidermal growth factor (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-09-04
    Description: The mitogenic effect of somatomedin B on human cultured glial cells was neutralized by the addition of antibodies to mouse epidermal growth factor. Somatomedin B contained epidermal growth factor--like activity, competing for binding to the epidermal growth factor receptor. It is concluded that contaminating epidermal growth factor may explain the entire mitogenic activity of somatomedin B.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Heldin, C H -- Wasteson, A -- Fryklund, L -- Westermark, B -- New York, N.Y. -- Science. 1981 Sep 4;213(4512):1122-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6973821" target="_blank"〉PubMed〈/a〉

Spike generation was blocked by MnCl2. In view of this evidence for calcium-spike electrogenesis and previous evidence of secretory activity in these cells, this cell line (DMS 53) can provide a model for the study of excitation-secretion behavior in human neoplastic cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCann, F V -- Pettengill, O S -- Cole, J J -- Russell, J A -- Sorenson, G D -- CA 25845/CA/NCI NIH HHS/ -- DA 23108/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 5;212(4499):1155-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6262914" target="_blank"〉PubMed〈/a〉

    Substance P and somatostatin regulate sympathetic noradrenergic function (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-09-09
    Description: Peptidergic-noradrenergic interactions were examined in explants of rat sympathetic superior cervical ganglia and in cultures of dissociated cells. The putative peptide transmitters substance P and somatostatin each increased the activity of the catecholamine-synthesizing enzyme tyrosine hydroxylase after 1 week of exposure in culture. Maximal increases occurred at 10(-7) molar for each peptide, and either increasing or decreasing the concentration reduced the effects. Similar increases in tyrosine hydroxylase were produced by a metabolically stable agonist of substance P, while a substance P antagonist prevented the effects of the agonist. The data suggest that the increased tyrosine hydroxylase activity was mediated by peptide interaction with specific substance P receptors and that peptides may modulate sympathetic catecholaminergic function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kessler, J A -- Adler, J E -- Black, I B -- New York, N.Y. -- Science. 1983 Sep 9;221(4615):1059-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6192502" target="_blank"〉PubMed〈/a〉

    Action potentials in macrophages derived from human monocytes (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-02-25
    Description: The electrical activity of macrophages derived from human blood monocytes was recorded in vitro with intracellular microelectrodes and was analyzed with computer-assisted data acquisition and analysis techniques. In cells impaled 6 to 8 days after the cultures were prepared, the resting potentials reached a maximum value of -72 millivolts. The cells were electrically excitable; spikes exhibited a slow upstroke, a fast downstroke, a discrete threshold, a large overshoot, and a brief undershoot. Repetitive firing was induced by a maintained depolarizing current. A positive relation was observed between transmembrane currents and resting potential. Voltage-current relations were nonrectifying for subthreshold current injections. Since these cells had not been treated with any specific activation factors, the electrical activity recorded is evidence for the presence of voltage-dependent inward and outward currents in the membranes of mature macrophages. The electrical signals generated by these cells may be useful for the assay of sensor and effector functions of macrophages, such as chemotaxis, receptor-ligand interactions, and phagocytosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCann, F V -- Cole, J J -- Guyre, P M -- Russell, J A -- AM0535/AM/NIADDK NIH HHS/ -- BRSG05392/RS/DRS NIH HHS/ -- CA17323/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 Feb 25;219(4587):991-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6823563" target="_blank"〉PubMed〈/a〉

    Somatomedin-C mediates growth hormone negative feedback by effects on both the hypothalamus and the pituitary (1981)

    Description: Somatomedin-C stimulates somatostatin release to a maximum of 390 percent of basal release during short-term (20-minute) incubation of rat hypothalamus. It has no effect on basal or stimulated growth hormone release from primary cultures of rat adenohypophyseal cells during a 4-hour incubation, but inhibits stimulated release by more that 90 percent after 24 hours. These findings suggest that somatomedin-C participates in the growth hormone negative feedback loop with an immediate effect on hypothalamic somatostatin and a delayed effect on the anterior pituitary.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berelowitz, M -- Szabo, M -- Frohman, L A -- Firestone, S -- Chu, L -- Hintz, R L -- AM 18722/AM/NIADDK NIH HHS/ -- AM 24085/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 12;212(4500):1279-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6262917" target="_blank"〉PubMed〈/a〉

    Description: Sympathetic neurons from newborn rats, cultured for 1 month or longer in the virtual absence of nonneuronal cells, were capable of regenerating neurites after neuritotomy. Regeneration occurred even after nerve growth factor was withdrawn from the cultures, although it was much less extensive and appeared limited to a few days following neuritotomy. Even after 29 days of nerve growth factor deprivation, reintroduction of the protein prompted a resumption of neurite growth. Possible roles of both nerve growth factor-independent and -dependent components in adult nerve regeneration are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Campenot, R B -- NS15559/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 30;214(4520):579-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7292000" target="_blank"〉PubMed〈/a〉

    Growth arrest and morphological change of human breast cancer cells by dibutyryl cyclic AMP and L-arginine (1981)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 1981-10-02
    Description: The growth in vitro of human breast cancer cells, line MCF-7, was inhibited by a daily supplement of L-arginine (1 milligram per milliliter). Arginine acted synergistically with dibutyryl adenosine 3',5'-monophosphate (cyclic AMP) (10(-6) molar) to enhance the growth inhibitory effect: the cell replication ceased completely within 2 days after treatment. The growth arrest accompanied a change in cell morphology and was preceded by increases in the cellular concentration of cyclic AMP, adenylate cyclase, and type II cyclic AMP-dependent protein kinase activities as well as a decrease of estrogen binding activity. The results suggest that growth of human breast cancer cells is subject to cyclic AMP-mediated regulation and that arginine may play a specific role in this process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cho-Chung, Y S -- Clair, T -- Bodwin, J S -- Berghoffer, B -- New York, N.Y. -- Science. 1981 Oct 2;214(4516):77-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6269181" target="_blank"〉PubMed〈/a〉

    Description: A clone of L1210 mouse leukemia cells selected for resistance to both the antiviral and anticellular properties of mouse interferon were essentially devoid of fatty acid cyclooxygenase activity. Experiments in which broken cell preparations were mixed or the two cell types were cultivated together failed to indicate the presence of a diffusible enzyme inhibitor. Fatty acid lipoxygenase activity of similar magnitude was detectable in both cell types. A selective impairment of fatty acid cyclooxygenase in interferon-resistant cells is consistent with recently described data suggesting that this enzyme may play a crucial role in mediating the antiviral and anticellular effects of interferon.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chandrabose, K A -- Cuatrecasas, P -- Pottathil, R -- Lang, D J -- New York, N.Y. -- Science. 1981 Apr 17;212(4492):329-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6163214" target="_blank"〉PubMed〈/a〉

    Elastin fragments attract macrophage precursors to diseased sites in pulmonary emphysema (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-05-22
    Description: This study suggests one mechanism by which alveolar macrophages accumulate in the lung in pulmonary emphysema: elastin fragments generated at the diseased sites are potent chemoattractants for monocytes, the precursors of the macrophages. The most chemotactic elastin fragments have a molecular weight between 10,000 and 50,000 and are active at concentrations as low as 3 nanograms per milliliter. By comparison, elastin fragments with higher molecular weights and desmosines are active at concentrations greater than 0.3 microgram per milliliter. In addition, preincubation of monocytes with the 10,000- to 50,000-dalton elastin impairs the ability of the cells to migrate toward elastin fragments but not toward activated serum. Fragments of tropoelastin are not chemotactic for monocytes. Because elastin, but not tropoelastin, contains lysyl-derived cross-links, these structures may be the active chemotactic site on the elastin fragments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hunninghake, G W -- Davidson, J M -- Rennard, S -- Szapiel, S -- Gadek, J E -- Crystal, R G -- New York, N.Y. -- Science. 1981 May 22;212(4497):925-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233186" target="_blank"〉PubMed〈/a〉

    The posterior pituitary: regulation of anterior pituitary prolactin secretion (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-08-07
    Description: Removal of the posterior pituitary from anesthetized male rats results in a prompt and significant increase in circulating prolactin that is reversed by the injection of dopamine. Posterior pituitary extracts, which contain high concentrations of endogenous dopamine, inhibit prolactin secretion from isolated anterior pituitary cells. This inhibition is prevented by incubation of the cells with the dopamine receptor antagonist (+)-butaclamol. The data show that posterior pituitary dopamine reaches the anterior pituitary via the short hypophysial portal vessels and participates in the regulation of prolactin secretion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peters, L L -- Hoefer, M T -- Ben-Jonathan, N -- HD 14348/HD/NICHD NIH HHS/ -- NS-13234/NS/NINDS NIH HHS/ -- NS-219/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Aug 7;213(4508):659-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7256264" target="_blank"〉PubMed〈/a〉

    Compartmentalization of cyclic AMP during phagocytosis by human neutrophilic granulocytes (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-01-23
    Description: Immunocytochemistry shows that early during phagocytosis of zymosan, adenosine 3',5'-monophosphate (cyclic AMP) appears on the cell surface before the phagosome is internalized. The appearance of cyclic AMP on the cell surface is coincident with that of granule products and regulatory subunit of type I cyclic AMP-dependent protein kinase. Guanosine 3',5'-monophosphate is not associated with the initiation site of phagocytosis, but is observed throughout the granular cytoplasmic region. This sharply localized accumulation of cyclic AMP may serve as a signal for the initiation of phagocytosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pryzwansky, K B -- Steiner, A L -- Spitznagel, J K -- Kapoor, C L -- 02430-22/PHS HHS/ -- AM17438/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Jan 23;211(4480):407-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6261328" target="_blank"〉PubMed〈/a〉

    Lectins mimic insulin in the induction of tyrosine aminotransferase (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-11-13
    Description: Various lectins were found to induce tyrosine aminotransferase in H-35 rat hepatoma cells grown in monolayer culture. Wheat germ agglutinin gave a maximal induction of tyrosine aminotransferase 6 hours after its addition. The induction time course was similar to that elicited by insulin. Fourteen micrograms of wheat germ agglutinin per milliliter gave half-maximal enzyme induction and 50 micrograms per milliliter gave the maximal response. The induction of tyrosine aminotransferase by wheat germ agglutinin was additive with the induction by either dexamethasone or dibutyryl adenosine 3',5'-monophosphate, but was not additive with the tyrosine amino transferase induction by insulin. Wheat germ agglutinin also mimicked insulin in the inhibition of cellular protein degradation in the absence of serum. The insulin-like effects of lectins should be considered in lectin-mediated manipulations such as agglutination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, J D -- Liu, A Y -- AM20274/AM/NIADDK NIH HHS/ -- GM 07258/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1981 Nov 13;214(4522):799-800.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6117128" target="_blank"〉PubMed〈/a〉

    Publication Date: 1983-09-09
    Description: Vasoactive intestinal peptide stimulated the synthesis of adenosine 3',5'-monophosphate in fractions of isolated carp horizontal cells. When applied extracellularly to isolated and cultured horizontal cells, the peptide also induced a slow depolarization (30 to 40 millivolts) accompanied by a decrease in membrane resistance. However, analogs of adenosine 3',5'-monophosphate applied extracellularly or intracellularly, and forscolin applied extracellularly, had no effect on the membrane potential of cultured horizontal cells, indicating that the induced depolarization was not related to the accumulation of adenosine 3',5'-monophosphate in these cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lasater, E M -- Watling, K J -- Dowling, J E -- EY-00811/EY/NEI NIH HHS/ -- EY-00824/EY/NEI NIH HHS/ -- EY-05476/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1983 Sep 9;221(4615):1070-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6308770" target="_blank"〉PubMed〈/a〉

    Mobilization of cellular calcium-45 and lead-210: effect of physiological stimuli (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-15
    Description: Isolated rat hepatocytes in primary culture were used as a model system to evaluate the effects of selected hormones and culture conditions on the efflux of calcium-45 and lead-210 from cells labeled with these isotopes. Alpha-adrenergic stimuli, angiotensin, vasopressin, dibutyryl adenosine 3',5'-monophosphate, and reduced phosphate concentrations in the medium increased the efflux of calcium-45 and lead-210. Glucagon and insulin had no effect, but increased phosphate concentrations decreased the efflux of both isotopes. Experiments with hepatocytes cultured in a medium free of calcium and lead demonstrated that the increased efflux of calcium-45 and lead-210 induced by hormones was the result of mobilization of the ions from intracellular stores. The data indicate that the physiological stimuli that mobilized calcium ions also mobilized lead ions, and that the mobilized lead would be available to interact with calcium-mediated cell functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pounds, J G -- Mittelstaedt, R A -- New York, N.Y. -- Science. 1983 Apr 15;220(4594):308-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6301003" target="_blank"〉PubMed〈/a〉

    Description: The molecularly cloned, long terminal repeat (LTR) of the Moloney sarcoma virus (M-MSV) provirus has been covalently linked to c-mos, the cellular homolog of the M-MSV-specific sequence, v-mos. These newly constructed clones lack any M-MSV-derived sequences other than the LTR, but in DNA transfection assays they transform cells as efficiently as cloned subgenomic M-MSV fragments containing both v-mos and LTR. Cells transformed by LTR:c-mos hybrid molecules contain additional copies of mos DNA, and several size classes of polyadenylated RNA's with sequence homology to mos. The activation of the transforming potential of c-mos by the proviral LTR suggests a model whereby LTR-like elements could activate other normal cell sequences with oncogenic potential.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blair, D G -- Oskarsson, M -- Wood, T G -- McClements, W L -- Fischinger, P J -- Vande Woude, G G -- New York, N.Y. -- Science. 1981 May 22;212(4497):941-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233190" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-12-18
    Description: Epinephrine and isoproterenol provoke primary chick myoblasts to initiate precocious cell fusion. Both the rise in intracellular adenosine 3' ,5-monophosphate (cyclic AMP) and cell fusion generated by these effectors are prevented by propranolol, which is a specific blocker of the beta-adrenergic receptor. Propranolol has no effect either on the precocious cell fusion provoked by prostaglandin E or on cell fusion in control cultures. The results support the idea that a rise in cyclic AMP is the critical intracellular change responsible for initiating events that culminate in myoblast differentiation 4 to 5 hours later. They also indicate that the culminate in myoblast differentiation 4 to 5 hours later. They also indicate that the hormone responsible for the positive regulation of myoblast differentiation in vitro is not acting through the beta-adrenergic receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Curtis, D H -- Zalin, R J -- New York, N.Y. -- Science. 1981 Dec 18;214(4527):1355-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6274017" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1981-05-01
    Description: When the incorporation of tritiated thymidine into acid insoluble material was measured, ribavirin appeared to be a potent inhibitor of DNA synthesis in KB cells and human lymphocytes. Inhibition was nearly 100-fold less, however, when DNA synthesis was measured by incorporation of phosphorus-32-labeled phosphate or by DNA fluorescence. The potent inhibition detected by incorporation of tritiated thymidine into DNA actually was the result of a potent effect on the labeling of deoxythymidine triphosphate, not on the synthesis of DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drach, J C -- Thomas, M A -- Barnett, J W -- Smith, S H -- Shipman, C Jr -- DE 02731/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1981 May 1;212(4494):549-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209549" target="_blank"〉PubMed〈/a〉

    Description: Simultaneous recordings of calcium action potentials directly from growth cones and from somata of neuroblastoma cells indicated that they could be generated in the neurites at or near growth cones. Growth cone responses were measured with a fluorescent voltage-sensitive dye and a 5-milliwatt helium-neon laser microbeam as a monitoring light source.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grinvald, A -- Farber, I C -- NS14716/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Jun 5;212(4499):1164-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233210" target="_blank"〉PubMed〈/a〉
