    Description: Deregulation of Akt/protein kinase B (PKB) is implicated in the pathogenesis of cancer and diabetes. Akt/PKB activation requires the phosphorylation of Thr308 in the activation loop by the phosphoinositide-dependent kinase 1 (PDK1) and Ser473 within the carboxyl-terminal hydrophobic motif by an unknown kinase. We show that in Drosophila and human cells the target of rapamycin (TOR) kinase and its associated protein rictor are necessary for Ser473 phosphorylation and that a reduction in rictor or mammalian TOR (mTOR) expression inhibited an Akt/PKB effector. The rictor-mTOR complex directly phosphorylated Akt/PKB on Ser473 in vitro and facilitated Thr308 phosphorylation by PDK1. Rictor-mTOR may serve as a drug target in tumors that have lost the expression of PTEN, a tumor suppressor that opposes Akt/PKB activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sarbassov, D D -- Guertin, David A -- Ali, Siraj M -- Sabatini, David M -- R01 AI47389/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2005 Feb 18;307(5712):1098-101.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research and Department of Biology, Massachusetts Institute of Technology, Nine Cambridge Center, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15718470" target="_blank"〉PubMed〈/a〉

    Description: Most protein phosphatases have little intrinsic substrate specificity, making selective pharmacological inhibition of specific dephosphorylation reactions a challenging problem. In a screen for small molecules that protect cells from endoplasmic reticulum (ER) stress, we identified salubrinal, a selective inhibitor of cellular complexes that dephosphorylate eukaryotic translation initiation factor 2 subunit alpha (eIF2alpha). Salubrinal also blocks eIF2alpha dephosphorylation mediated by a herpes simplex virus protein and inhibits viral replication. These results suggest that selective chemical inhibitors of eIF2alpha dephosphorylation may be useful in diseases involving ER stress or viral infection. More broadly, salubrinal demonstrates the feasibility of selective pharmacological targeting of cellular dephosphorylation events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boyce, Michael -- Bryant, Kevin F -- Jousse, Celine -- Long, Kai -- Harding, Heather P -- Scheuner, Donalyn -- Kaufman, Randal J -- Ma, Dawei -- Coen, Donald M -- Ron, David -- Yuan, Junying -- AI19838/AI/NIAID NIH HHS/ -- AI26077/AI/NIAID NIH HHS/ -- DDK42394/DK/NIDDK NIH HHS/ -- DK47119/DK/NIDDK NIH HHS/ -- ES08681/ES/NIEHS NIH HHS/ -- GM64703/GM/NIGMS NIH HHS/ -- NS35138/NS/NINDS NIH HHS/ -- R37-AG012859/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2005 Feb 11;307(5711):935-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15705855" target="_blank"〉PubMed〈/a〉

    Description: The disrupted in schizophrenia 1 (DISC1) gene is a candidate susceptibility factor for schizophrenia, but its mechanistic role in the disorder is unknown. Here we report that the gene encoding phosphodiesterase 4B (PDE4B) is disrupted by a balanced translocation in a subject diagnosed with schizophrenia and a relative with chronic psychiatric illness. The PDEs inactivate adenosine 3',5'-monophosphate (cAMP), a second messenger implicated in learning, memory, and mood. We show that DISC1 interacts with the UCR2 domain of PDE4B and that elevation of cellular cAMP leads to dissociation of PDE4B from DISC1 and an increase in PDE4B activity. We propose a mechanistic model whereby DISC1 sequesters PDE4B in resting cells and releases it in an activated state in response to elevated cAMP.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Millar, J Kirsty -- Pickard, Benjamin S -- Mackie, Shaun -- James, Rachel -- Christie, Sheila -- Buchanan, Sebastienne R -- Malloy, M Pat -- Chubb, Jennifer E -- Huston, Elaine -- Baillie, George S -- Thomson, Pippa A -- Hill, Elaine V -- Brandon, Nicholas J -- Rain, Jean-Christophe -- Camargo, L Miguel -- Whiting, Paul J -- Houslay, Miles D -- Blackwood, Douglas H R -- Muir, Walter J -- Porteous, David J -- G8604010/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Nov 18;310(5751):1187-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Genetics Section, Molecular Medicine Centre, University of Edinburgh, Edinburgh EH4 2XU, UK.

    Description: Lighter variations of pigmentation in humans are associated with diminished number, size, and density of melanosomes, the pigmented organelles of melanocytes. Here we show that zebrafish golden mutants share these melanosomal changes and that golden encodes a putative cation exchanger slc24a5 (nckx5) that localizes to an intracellular membrane, likely the melanosome or its precursor. The human ortholog is highly similar in sequence and functional in zebrafish. The evolutionarily conserved ancestral allele of a human coding polymorphism predominates in African and East Asian populations. In contrast, the variant allele is nearly fixed in European populations, is associated with a substantial reduction in regional heterozygosity, and correlates with lighter skin pigmentation in admixed populations, suggesting a key role for the SLC24A5 gene in human pigmentation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamason, Rebecca L -- Mohideen, Manzoor-Ali P K -- Mest, Jason R -- Wong, Andrew C -- Norton, Heather L -- Aros, Michele C -- Jurynec, Michael J -- Mao, Xianyun -- Humphreville, Vanessa R -- Humbert, Jasper E -- Sinha, Soniya -- Moore, Jessica L -- Jagadeeswaran, Pudur -- Zhao, Wei -- Ning, Gang -- Makalowska, Izabela -- McKeigue, Paul M -- O'donnell, David -- Kittles, Rick -- Parra, Esteban J -- Mangini, Nancy J -- Grunwald, David J -- Shriver, Mark D -- Canfield, Victor A -- Cheng, Keith C -- CA73935/CA/NCI NIH HHS/ -- EY11308/EY/NEI NIH HHS/ -- HD37572/HD/NICHD NIH HHS/ -- HD40179/HD/NICHD NIH HHS/ -- HG002154/HG/NHGRI NIH HHS/ -- HL077910/HL/NHLBI NIH HHS/ -- RR017441/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2005 Dec 16;310(5755):1782-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Jake Gittlen Cancer Research Foundation, Department of Pathology, The Pennsylvania State University College of Medicine, Hershey, PA 17033, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16357253" target="_blank"〉PubMed〈/a〉

    Description: Aneuploidies are common chromosomal defects that result in growth and developmental deficits and high levels of lethality in humans. To gain insight into the biology of aneuploidies, we manipulated mouse embryonic stem cells and generated a trans-species aneuploid mouse line that stably transmits a freely segregating, almost complete human chromosome 21 (Hsa21). This "transchromosomic" mouse line, Tc1, is a model of trisomy 21, which manifests as Down syndrome (DS) in humans, and has phenotypic alterations in behavior, synaptic plasticity, cerebellar neuronal number, heart development, and mandible size that relate to human DS. Transchromosomic mouse lines such as Tc1 may represent useful genetic tools for dissecting other human aneuploidies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1378183/" 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/PMC1378183/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Doherty, Aideen -- Ruf, Sandra -- Mulligan, Claire -- Hildreth, Victoria -- Errington, Mick L -- Cooke, Sam -- Sesay, Abdul -- Modino, Sonie -- Vanes, Lesley -- Hernandez, Diana -- Linehan, Jacqueline M -- Sharpe, Paul T -- Brandner, Sebastian -- Bliss, Timothy V P -- Henderson, Deborah J -- Nizetic, Dean -- Tybulewicz, Victor L J -- Fisher, Elizabeth M C -- 076700/Wellcome Trust/United Kingdom -- MC_U117512674/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2005 Sep 23;309(5743):2033-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurodegenerative Disease, Institute of Neurology, Queen Square, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16179473" target="_blank"〉PubMed〈/a〉

    Description: Sites of transcription of polyadenylated and nonpolyadenylated RNAs for 10 human chromosomes were mapped at 5-base pair resolution in eight cell lines. Unannotated, nonpolyadenylated transcripts comprise the major proportion of the transcriptional output of the human genome. Of all transcribed sequences, 19.4, 43.7, and 36.9% were observed to be polyadenylated, nonpolyadenylated, and bimorphic, respectively. Half of all transcribed sequences are found only in the nucleus and for the most part are unannotated. Overall, the transcribed portions of the human genome are predominantly composed of interlaced networks of both poly A+ and poly A- annotated transcripts and unannotated transcripts of unknown function. This organization has important implications for interpreting genotype-phenotype associations, regulation of gene expression, and the definition of a gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cheng, Jill -- Kapranov, Philipp -- Drenkow, Jorg -- Dike, Sujit -- Brubaker, Shane -- Patel, Sandeep -- Long, Jeffrey -- Stern, David -- Tammana, Hari -- Helt, Gregg -- Sementchenko, Victor -- Piccolboni, Antonio -- Bekiranov, Stefan -- Bailey, Dione K -- Ganesh, Madhavan -- Ghosh, Srinka -- Bell, Ian -- Gerhard, Daniela S -- Gingeras, Thomas R -- New York, N.Y. -- Science. 2005 May 20;308(5725):1149-54.

    Description: Bacteria have developed mechanisms to communicate and compete with each other for limited environmental resources. We found that certain Escherichia coli, including uropathogenic strains, contained a bacterial growth-inhibition system that uses direct cell-to-cell contact. Inhibition was conditional, dependent upon the growth state of the inhibitory cell and the pili expression state of the target cell. Both a large cell-surface protein designated Contact-dependent inhibitor A (CdiA) and two-partner secretion family member CdiB were required for growth inhibition. The CdiAB system may function to regulate the growth of specific cells within a differentiated bacterial population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aoki, Stephanie K -- Pamma, Rupinderjit -- Hernday, Aaron D -- Bickham, Jessica E -- Braaten, Bruce A -- Low, David A -- AI23348/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2005 Aug 19;309(5738):1245-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular, Cellular, and Developmental Biology, University of California-Santa Barbara (UCSB), Santa Barbara, CA 93106, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16109881" target="_blank"〉PubMed〈/a〉

    Description: The positive buoyancy of marine fish eggs in sea water, allowed by hydration of the oocyte, is critical for their survival and dispersion in the ocean. We isolated an aquaporin, SaAQP1o, that belongs to a unique subfamily of aquaporin-1-like channels specifically evolved in teleosts and mainly expressed in the ovary. We further show that hormone-induced fish oocyte hydration is a highly controlled process based on the interplay between protein hydrolysis and the translocation of SaAQP1o to the plasma membrane, indicating a specialized physiological role for this aquaporin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fabra, Mercedes -- Raldua, Demetrio -- Power, Deborah M -- Deen, Peter M T -- Cerda, Joan -- New York, N.Y. -- Science. 2005 Jan 28;307(5709):545.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center of Aquaculture-Institut de Recerca i Tecnologia Agroalimentaries, Tarragona, Spain, and Reference Center in Aquaculture, Barcelona, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15681377" target="_blank"〉PubMed〈/a〉
