    Mouse development with a single E2F activator (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-07-03
    Description: The E2F family is conserved from Caenorhabditis elegans to mammals, with some family members having transcription activation functions and others having repressor functions. Whereas C. elegans and Drosophila melanogaster have a single E2F activator protein and repressor protein, mammals have at least three activator and five repressor proteins. Why such genetic complexity evolved in mammals is not known. To begin to evaluate this genetic complexity, we targeted the inactivation of the entire subset of activators, E2f1, E2f2, E2f3a and E2f3b, singly or in combination in mice. We demonstrate that E2f3a is sufficient to support mouse embryonic and postnatal development. Remarkably, expression of E2f3b or E2f1 from the E2f3a locus (E2f3a(3bki) or E2f3a(1ki), respectively) suppressed all the postnatal phenotypes associated with the inactivation of E2f3a. We conclude that there is significant functional redundancy among activators and that the specific requirement for E2f3a during postnatal development is dictated by regulatory sequences governing its selective spatiotemporal expression and not by its intrinsic protein functions. These findings provide a molecular basis for the observed specificity among E2F activators during development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4288824/" 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/PMC4288824/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsai, Shih-Yin -- Opavsky, Rene -- Sharma, Nidhi -- Wu, Lizhao -- Naidu, Shan -- Nolan, Eric -- Feria-Arias, Enrique -- Timmers, Cynthia -- Opavska, Jana -- de Bruin, Alain -- Chong, Jean-Leon -- Trikha, Prashant -- Fernandez, Soledad A -- Stromberg, Paul -- Rosol, Thomas J -- Leone, Gustavo -- K01CA102328/CA/NCI NIH HHS/ -- P01CA097189/CA/NCI NIH HHS/ -- R01 CA121275/CA/NCI NIH HHS/ -- R01 CA121275-03/CA/NCI NIH HHS/ -- R01CA121275/CA/NCI NIH HHS/ -- R01CA85619/CA/NCI NIH HHS/ -- R01HD042619/HD/NICHD NIH HHS/ -- R01HD047470/HD/NICHD NIH HHS/ -- T32CA106196/CA/NCI NIH HHS/ -- England -- Nature. 2008 Aug 28;454(7208):1137-41. doi: 10.1038/nature07066.

    New role of bone morphogenetic protein 7 in brown adipogenesis and energy expenditure (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-08-23
    Description: Adipose tissue is central to the regulation of energy balance. Two functionally different types of fat are present in mammals: white adipose tissue, the primary site of triglyceride storage, and brown adipose tissue, which is specialized in energy expenditure and can counteract obesity. Factors that specify the developmental fate and function of white and brown adipose tissue remain poorly understood. Here we demonstrate that whereas some members of the family of bone morphogenetic proteins (BMPs) support white adipocyte differentiation, BMP7 singularly promotes differentiation of brown preadipocytes even in the absence of the normally required hormonal induction cocktail. BMP7 activates a full program of brown adipogenesis including induction of early regulators of brown fat fate PRDM16 (PR-domain-containing 16; ref. 4) and PGC-1alpha (peroxisome proliferator-activated receptor-gamma (PPARgamma) coactivator-1alpha; ref. 5), increased expression of the brown-fat-defining marker uncoupling protein 1 (UCP1) and adipogenic transcription factors PPARgamma and CCAAT/enhancer-binding proteins (C/EBPs), and induction of mitochondrial biogenesis via p38 mitogen-activated protein (MAP) kinase-(also known as Mapk14) and PGC-1-dependent pathways. Moreover, BMP7 triggers commitment of mesenchymal progenitor cells to a brown adipocyte lineage, and implantation of these cells into nude mice results in development of adipose tissue containing mostly brown adipocytes. Bmp7 knockout embryos show a marked paucity of brown fat and an almost complete absence of UCP1. Adenoviral-mediated expression of BMP7 in mice results in a significant increase in brown, but not white, fat mass and leads to an increase in energy expenditure and a reduction in weight gain. These data reveal an important role of BMP7 in promoting brown adipocyte differentiation and thermogenesis in vivo and in vitro, and provide a potential new therapeutic approach for the treatment of obesity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2745972/" 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/PMC2745972/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tseng, Yu-Hua -- Kokkotou, Efi -- Schulz, Tim J -- Huang, Tian Lian -- Winnay, Jonathon N -- Taniguchi, Cullen M -- Tran, T Thien -- Suzuki, Ryo -- Espinoza, Daniel O -- Yamamoto, Yuji -- Ahrens, Molly J -- Dudley, Andrew T -- Norris, Andrew W -- Kulkarni, Rohit N -- Kahn, C Ronald -- K08 DK064906/DK/NIDDK NIH HHS/ -- K08 DK64906/DK/NIDDK NIH HHS/ -- P30 DK040561/DK/NIDDK NIH HHS/ -- P30 DK040561-13/DK/NIDDK NIH HHS/ -- P30 DK46200/DK/NIDDK NIH HHS/ -- R01 DK 060837/DK/NIDDK NIH HHS/ -- R01 DK077097/DK/NIDDK NIH HHS/ -- R01 DK077097-01A1/DK/NIDDK NIH HHS/ -- R01 DK077097-02/DK/NIDDK NIH HHS/ -- R01 DK67536/DK/NIDDK NIH HHS/ -- R21 DK070722/DK/NIDDK NIH HHS/ -- R21 DK070722-01/DK/NIDDK NIH HHS/ -- R21 DK070722-02/DK/NIDDK NIH HHS/ -- England -- Nature. 2008 Aug 21;454(7207):1000-4. doi: 10.1038/nature07221.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section on Obesity and Hormone Action, Joslin Diabetes Center, Harvard Medical School, Boston, Massachusetts 02215, USA. yu-hua.tseng@joslin.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18719589" target="_blank"〉PubMed〈/a〉

    HDAC2 negatively regulates memory formation and synaptic plasticity (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-05-09
    Description: Chromatin modifications, especially histone-tail acetylation, have been implicated in memory formation. Increased histone-tail acetylation induced by inhibitors of histone deacetylases (HDACis) facilitates learning and memory in wild-type mice as well as in mouse models of neurodegeneration. Harnessing the therapeutic potential of HDACis requires knowledge of the specific HDAC family member(s) linked to cognitive enhancement. Here we show that neuron-specific overexpression of HDAC2, but not that of HDAC1, decreased dendritic spine density, synapse number, synaptic plasticity and memory formation. Conversely, Hdac2 deficiency resulted in increased synapse number and memory facilitation, similar to chronic treatment with HDACis in mice. Notably, reduced synapse number and learning impairment of HDAC2-overexpressing mice were ameliorated by chronic treatment with HDACis. Correspondingly, treatment with HDACis failed to further facilitate memory formation in Hdac2-deficient mice. Furthermore, analysis of promoter occupancy revealed an association of HDAC2 with the promoters of genes implicated in synaptic plasticity and memory formation. Taken together, our results suggest that HDAC2 functions in modulating synaptic plasticity and long-lasting changes of neural circuits, which in turn negatively regulates learning and memory. These observations encourage the development and testing of HDAC2-selective inhibitors for human diseases associated with memory impairment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3498958/" 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/PMC3498958/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guan, Ji-Song -- Haggarty, Stephen J -- Giacometti, Emanuela -- Dannenberg, Jan-Hermen -- Joseph, Nadine -- Gao, Jun -- Nieland, Thomas J F -- Zhou, Ying -- Wang, Xinyu -- Mazitschek, Ralph -- Bradner, James E -- DePinho, Ronald A -- Jaenisch, Rudolf -- Tsai, Li-Huei -- R01 DA028301/DA/NIDA NIH HHS/ -- R01 DA028301-02/DA/NIDA NIH HHS/ -- R01 NS051874/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 May 7;459(7243):55-60. doi: 10.1038/nature07925.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Picower Institute for Learning and Memory, Department of Brain and Cognitive Sciences.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19424149" target="_blank"〉PubMed〈/a〉

    Pten in stromal fibroblasts suppresses mammary epithelial tumours (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-10-23
    Description: The tumour stroma is believed to contribute to some of the most malignant characteristics of epithelial tumours. However, signalling between stromal and tumour cells is complex and remains poorly understood. Here we show that the genetic inactivation of Pten in stromal fibroblasts of mouse mammary glands accelerated the initiation, progression and malignant transformation of mammary epithelial tumours. This was associated with the massive remodelling of the extracellular matrix (ECM), innate immune cell infiltration and increased angiogenesis. Loss of Pten in stromal fibroblasts led to increased expression, phosphorylation (T72) and recruitment of Ets2 to target promoters known to be involved in these processes. Remarkably, Ets2 inactivation in Pten stroma-deleted tumours ameliorated disruption of the tumour microenvironment and was sufficient to decrease tumour growth and progression. Global gene expression profiling of mammary stromal cells identified a Pten-specific signature that was highly represented in the tumour stroma of patients with breast cancer. These findings identify the Pten-Ets2 axis as a critical stroma-specific signalling pathway that suppresses mammary epithelial tumours.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2767301/" 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/PMC2767301/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trimboli, Anthony J -- Cantemir-Stone, Carmen Z -- Li, Fu -- Wallace, Julie A -- Merchant, Anand -- Creasap, Nicholas -- Thompson, John C -- Caserta, Enrico -- Wang, Hui -- Chong, Jean-Leon -- Naidu, Shan -- Wei, Guo -- Sharma, Sudarshana M -- Stephens, Julie A -- Fernandez, Soledad A -- Gurcan, Metin N -- Weinstein, Michael B -- Barsky, Sanford H -- Yee, Lisa -- Rosol, Thomas J -- Stromberg, Paul C -- Robinson, Michael L -- Pepin, Francois -- Hallett, Michael -- Park, Morag -- Ostrowski, Michael C -- Leone, Gustavo -- P01 CA097189/CA/NCI NIH HHS/ -- P01 CA097189-050002/CA/NCI NIH HHS/ -- P01CA097189/CA/NCI NIH HHS/ -- R01 CA053271/CA/NCI NIH HHS/ -- R01 CA085619/CA/NCI NIH HHS/ -- R01 CA085619-05/CA/NCI NIH HHS/ -- R01 CA121275/CA/NCI NIH HHS/ -- R01 CA121275-02/CA/NCI NIH HHS/ -- R01 HD047470/HD/NICHD NIH HHS/ -- R01 HD047470-05/HD/NICHD NIH HHS/ -- R01CA053271/CA/NCI NIH HHS/ -- R01CA85619/CA/NCI NIH HHS/ -- R01HD47470/HD/NICHD NIH HHS/ -- England -- Nature. 2009 Oct 22;461(7267):1084-91. doi: 10.1038/nature08486.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, College of Biological Sciences, The Ohio State University, Columbus, Ohio 43210, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19847259" target="_blank"〉PubMed〈/a〉

    Transgenic inhibition of synaptic transmission reveals role of CA3 output in hippocampal learning (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-01-26
    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.

    Mutations in the FUS/TLS gene on chromosome 16 cause familial amyotrophic lateral sclerosis (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-03-03
    Description: Amyotrophic lateral sclerosis (ALS) is a fatal degenerative motor neuron disorder. Ten percent of cases are inherited; most involve unidentified genes. We report here 13 mutations in the fused in sarcoma/translated in liposarcoma (FUS/TLS) gene on chromosome 16 that were specific for familial ALS. The FUS/TLS protein binds to RNA, functions in diverse processes, and is normally located predominantly in the nucleus. In contrast, the mutant forms of FUS/TLS accumulated in the cytoplasm of neurons, a pathology that is similar to that of the gene TAR DNA-binding protein 43 (TDP43), whose mutations also cause ALS. Neuronal cytoplasmic protein aggregation and defective RNA metabolism thus appear to be common pathogenic mechanisms involved in ALS and possibly in other neurodegenerative disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kwiatkowski, T J Jr -- Bosco, D A -- Leclerc, A L -- Tamrazian, E -- Vanderburg, C R -- Russ, C -- Davis, A -- Gilchrist, J -- Kasarskis, E J -- Munsat, T -- Valdmanis, P -- Rouleau, G A -- Hosler, B A -- Cortelli, P -- de Jong, P J -- Yoshinaga, Y -- Haines, J L -- Pericak-Vance, M A -- Yan, J -- Ticozzi, N -- Siddique, T -- McKenna-Yasek, D -- Sapp, P C -- Horvitz, H R -- Landers, J E -- Brown, R H Jr -- New York, N.Y. -- Science. 2009 Feb 27;323(5918):1205-8. doi: 10.1126/science.1166066.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Massachusetts General Hospital, 114 16th Street, Charlestown, MA 02129, USA. tkwiatkowski@partners.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19251627" target="_blank"〉PubMed〈/a〉

    A functional role for adult hippocampal neurogenesis in spatial pattern separation (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-07-11
    Description: The dentate gyrus (DG) of the mammalian hippocampus is hypothesized to mediate pattern separation-the formation of distinct and orthogonal representations of mnemonic information-and also undergoes neurogenesis throughout life. How neurogenesis contributes to hippocampal function is largely unknown. Using adult mice in which hippocampal neurogenesis was ablated, we found specific impairments in spatial discrimination with two behavioral assays: (i) a spatial navigation radial arm maze task and (ii) a spatial, but non-navigable, task in the mouse touch screen. Mice with ablated neurogenesis were impaired when stimuli were presented with little spatial separation, but not when stimuli were more widely separated in space. Thus, newborn neurons may be necessary for normal pattern separation function in the DG of adult mice.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997634/" 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/PMC2997634/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clelland, C D -- Choi, M -- Romberg, C -- Clemenson, G D Jr -- Fragniere, A -- Tyers, P -- Jessberger, S -- Saksida, L M -- Barker, R A -- Gage, F H -- Bussey, T J -- NS-050217/NS/NINDS NIH HHS/ -- R01 NS050217/NS/NINDS NIH HHS/ -- R01 NS050217-05/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 10;325(5937):210-3. doi: 10.1126/science.1173215.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, Salk Institute for Biological Studies, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19590004" target="_blank"〉PubMed〈/a〉

    Uncharged tRNA and sensing of amino acid deficiency in mammalian piriform cortex (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-03-19
    Description: Recognizing a deficiency of indispensable amino acids (IAAs) for protein synthesis is vital for dietary selection in metazoans, including humans. Cells in the brain's anterior piriform cortex (APC) are sensitive to IAA deficiency, signaling diet rejection and foraging for complementary IAA sources, but the mechanism is unknown. Here we report that the mechanism for recognizing IAA-deficient foods follows the conserved general control (GC) system, wherein uncharged transfer RNA induces phosphorylation of eukaryotic initiation factor 2 (eIF2) via the GC nonderepressing 2 (GCN2) kinase. Thus, a basic mechanism of nutritional stress management functions in mammalian brain to guide food selection for survival.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hao, Shuzhen -- Sharp, James W -- Ross-Inta, Catherine M -- McDaniel, Brent J -- Anthony, Tracy G -- Wek, Ronald C -- Cavener, Douglas R -- McGrath, Barbara C -- Rudell, John B -- Koehnle, Thomas J -- Gietzen, Dorothy W -- GM49164/GM/NIGMS NIH HHS/ -- NS043231/NS/NINDS NIH HHS/ -- NS33347/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2005 Mar 18;307(5716):1776-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Veterinary Medicine, Department of Anatomy, Physiology and Cell Biology, University of California, Davis, CA 95616, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15774759" target="_blank"〉PubMed〈/a〉

    The enigma of prokaryotic life in deep hypersaline anoxic basins (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-01-08
    Description: Deep hypersaline anoxic basins in the Mediterranean Sea are a legacy of dissolution of ancient subterranean salt deposits from the Miocene period. Our study revealed that these hypersaline basins are not biogeochemical dead ends, but support in situ sulfate reduction, methanogenesis, and heterotrophic activity. A wide diversity of prokaryotes was observed, including a new, abundant, deeply branching order within the Euryarchaeota. Furthermore, we demonstrated the presence of a unique, metabolically active microbial community in the Discovery basin, which is one of the most extreme terrestrial saline environments known, as it is almost saturated with MgCl2 (5 M).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van der Wielen, Paul W J J -- Bolhuis, Henk -- Borin, Sara -- Daffonchio, Daniele -- Corselli, Cesare -- Giuliano, Laura -- D'Auria, Giuseppe -- de Lange, Gert J -- Huebner, Andreas -- Varnavas, Sotirios P -- Thomson, John -- Tamburini, Christian -- Marty, Danielle -- McGenity, Terry J -- Timmis, Kenneth N -- BioDeep Scientific Party -- New York, N.Y. -- Science. 2005 Jan 7;307(5706):121-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Microbial Ecology, University of Groningen, 9751 NN Haren, Netherlands. paul.van.der.wielen@kiwa.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15637281" target="_blank"〉PubMed〈/a〉
