    Description: During mouse embryogenesis, reversion of imprinted X chromosome inactivation in the pluripotent inner cell mass of the female blastocyst is initiated by the repression of Xist from the paternal X chromosome. Here we report that key factors supporting pluripotency-Nanog, Oct3/4, and Sox2-bind within Xist intron 1 in undifferentiated embryonic stem (ES) cells. Whereas Nanog null ES cells display a reversible and moderate up-regulation of Xist in the absence of any apparent modification of Oct3/4 and Sox2 binding, the drastic release of all three factors from Xist intron 1 triggers rapid ectopic accumulation of Xist RNA. We conclude that the three main genetic factors underlying pluripotency cooperate to repress Xist and thus couple X inactivation reprogramming to the control of pluripotency during embryogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Navarro, Pablo -- Chambers, Ian -- Karwacki-Neisius, Violetta -- Chureau, Corinne -- Morey, Celine -- Rougeulle, Claire -- Avner, Philip -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Sep 19;321(5896):1693-5. doi: 10.1126/science.1160952.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut Pasteur, Unite de Genetique Moleculaire Murine, CNRS, URA2578, F-75015, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18802003" target="_blank"〉PubMed〈/a〉

    Description: The hippocampus is an area of the brain involved in learning and memory. It contains parallel excitatory pathways referred to as the trisynaptic pathway (which carries information as follows: entorhinal cortex --〉 dentate gyrus --〉 CA3 --〉 CA1 --〉 entorhinal cortex) and the monosynaptic pathway (entorhinal cortex --〉 CA1 --〉 entorhinal cortex). We developed a generally applicable tetanus toxin-based method for transgenic mice that permits inducible and reversible inhibition of synaptic transmission and applied it to the trisynaptic pathway while preserving transmission in the monosynaptic pathway. We found that synaptic output from CA3 in the trisynaptic pathway is dispensable and the short monosynaptic pathway is sufficient for incremental spatial learning. In contrast, the full trisynaptic pathway containing CA3 is required for rapid one-trial contextual learning, for pattern completion-based memory recall, and for spatial tuning of CA1 cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakashiba, Toshiaki -- Young, Jennie Z -- McHugh, Thomas J -- Buhl, Derek L -- Tonegawa, Susumu -- P50-MH58880/MH/NIMH NIH HHS/ -- R01-MH078821/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2008 Feb 29;319(5867):1260-4. doi: 10.1126/science.1151120.

    Description: Retinoic acid (RA) is an essential extrinsic inducer of meiotic initiation in mammalian germ cells. However, RA acts too widely in mammalian development to account, by itself, for the cell-type and temporal specificity of meiotic initiation. We considered parallels to yeast, in which extrinsic and intrinsic factors combine to restrict meiotic initiation. We demonstrate that, in mouse embryos, extrinsic and intrinsic factors together regulate meiotic initiation. The mouse RNA-binding protein DAZL, which is expressed by postmigratory germ cells, is a key intrinsic factor, enabling those cells to initiate meiosis in response to RA. Within a brief developmental window, Dazl-expressing germ cells in both XX and XY embryos actively acquire the ability to interpret RA as a meiosis-inducing signal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Yanfeng -- Gill, Mark E -- Koubova, Jana -- Page, David C -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Dec 12;322(5908):1685-7. doi: 10.1126/science.1166340.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Whitehead Institute, and Department of Biology, Massachusetts Institute of Technology, 9 Cambridge Center, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19074348" target="_blank"〉PubMed〈/a〉

    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〉
