    Pivotal roles of cGAS-cGAMP signaling in antiviral defense and immune adjuvant effects (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-08-31
    Description: Invasion of microbial DNA into the cytoplasm of animal cells triggers a cascade of host immune reactions that help clear the infection; however, self DNA in the cytoplasm can cause autoimmune diseases. Biochemical approaches led to the identification of cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) synthase (cGAS) as a cytosolic DNA sensor that triggers innate immune responses. Here, we show that cells from cGAS-deficient (cGas(-/-)) mice, including fibroblasts, macrophages, and dendritic cells, failed to produce type I interferons and other cytokines in response to DNA transfection or DNA virus infection. cGas(-/-) mice were more susceptible to lethal infection with herpes simplex virus 1 (HSV1) than wild-type mice. We also show that cGAMP is an adjuvant that boosts antigen-specific T cell activation and antibody production in mice.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3863637/" 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/PMC3863637/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Xiao-Dong -- Wu, Jiaxi -- Gao, Daxing -- Wang, Hua -- Sun, Lijun -- Chen, Zhijian J -- 5T32AI070116/AI/NIAID NIH HHS/ -- AI-093967/AI/NIAID NIH HHS/ -- R01 AI093967/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1390-4. doi: 10.1126/science.1244040.

    The human THAP9 gene encodes an active P-element DNA transposase (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-01-26
    Description: The human genome contains ~50 genes that were derived from transposable elements or transposons, and many are now integral components of cellular gene expression programs. The human THAP9 gene is related to the Drosophila P-element transposase. Here, we show that human THAP9 can mobilize Drosophila P-elements in both Drosophila and human cells. Chimeric proteins formed between the Drosophila P-element transposase N-terminal THAP DNA binding domain and the C-terminal regions of human THAP9 can also mobilize Drosophila P elements. Our results indicate that human THAP9 is an active DNA transposase that, although "domesticated," still retains the catalytic activity to mobilize P transposable elements across species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3779457/" 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/PMC3779457/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Majumdar, Sharmistha -- Singh, Anita -- Rio, Donald C -- R01 GM048862/GM/NIGMS NIH HHS/ -- R01 GM094890/GM/NIGMS NIH HHS/ -- R01 GM097352/GM/NIGMS NIH HHS/ -- R01 GM104385/GM/NIGMS NIH HHS/ -- R01GM094890/GM/NIGMS NIH HHS/ -- R01GM104385/GM/NIGMS NIH HHS/ -- R01GM48862/GM/NIGMS NIH HHS/ -- R01GM61987/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Jan 25;339(6118):446-8. doi: 10.1126/science.1231789.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley, CA 94720-3204, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23349291" target="_blank"〉PubMed〈/a〉

    The human language-associated gene SRPX2 regulates synapse formation and vocalization in mice (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-11-02
    Description: Synapse formation in the developing brain depends on the coordinated activity of synaptogenic proteins, some of which have been implicated in a number of neurodevelopmental disorders. Here, we show that the sushi repeat-containing protein X-linked 2 (SRPX2) gene encodes a protein that promotes synaptogenesis in the cerebral cortex. In humans, SRPX2 is an epilepsy- and language-associated gene that is a target of the foxhead box protein P2 (FoxP2) transcription factor. We also show that FoxP2 modulates synapse formation through regulating SRPX2 levels and that SRPX2 reduction impairs development of ultrasonic vocalization in mice. Our results suggest FoxP2 modulates the development of neural circuits through regulating synaptogenesis and that SRPX2 is a synaptogenic factor that plays a role in the pathogenesis of language disorders.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3903157/" 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/PMC3903157/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sia, G M -- Clem, R L -- Huganir, R L -- NS050274/NS/NINDS NIH HHS/ -- P30 NS050274/NS/NINDS NIH HHS/ -- P50 MH084020/MH/NIMH NIH HHS/ -- P50MH084020/MH/NIMH NIH HHS/ -- R01 MH095058/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Nov 22;342(6161):987-91. doi: 10.1126/science.1245079.
