    Description: Isolated for the first time in 1982 from human gastric biopsy, Helicobacter pylori is responsible for gastritis, peptic ulcer, and gastric cancer. A pathogenicity island acquired by horizontal transfer, coding for a type IV secretion system, is a major determinant of virulence. The infection is now treated with antibiotics, and vaccines are in preparation. The geographic distribution suggests coevolution of man and Helicobacter pylori.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Covacci, A -- Telford, J L -- Del Giudice, G -- Parsonnet, J -- Rappuoli, R -- New York, N.Y. -- Science. 1999 May 21;284(5418):1328-33.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉IRIS, Chiron SpA, Via Fiorentina 1, 53100 Siena, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10334982" target="_blank"〉PubMed〈/a〉

    Description: The human malaria parasite Plasmodium vivax is responsible for 25-40% of the approximately 515 million annual cases of malaria worldwide. Although seldom fatal, the parasite elicits severe and incapacitating clinical symptoms and often causes relapses months after a primary infection has cleared. Despite its importance as a major human pathogen, P. vivax is little studied because it cannot be propagated continuously in the laboratory except in non-human primates. We sequenced the genome of P. vivax to shed light on its distinctive biological features, and as a means to drive development of new drugs and vaccines. Here we describe the synteny and isochore structure of P. vivax chromosomes, and show that the parasite resembles other malaria parasites in gene content and metabolic potential, but possesses novel gene families and potential alternative invasion pathways not recognized previously. Completion of the P. vivax genome provides the scientific community with a valuable resource that can be used to advance investigation into this neglected species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2651158/" 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/PMC2651158/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carlton, Jane M -- Adams, John H -- Silva, Joana C -- Bidwell, Shelby L -- Lorenzi, Hernan -- Caler, Elisabet -- Crabtree, Jonathan -- Angiuoli, Samuel V -- Merino, Emilio F -- Amedeo, Paolo -- Cheng, Qin -- Coulson, Richard M R -- Crabb, Brendan S -- Del Portillo, Hernando A -- Essien, Kobby -- Feldblyum, Tamara V -- Fernandez-Becerra, Carmen -- Gilson, Paul R -- Gueye, Amy H -- Guo, Xiang -- Kang'a, Simon -- Kooij, Taco W A -- Korsinczky, Michael -- Meyer, Esmeralda V-S -- Nene, Vish -- Paulsen, Ian -- White, Owen -- Ralph, Stuart A -- Ren, Qinghu -- Sargeant, Tobias J -- Salzberg, Steven L -- Stoeckert, Christian J -- Sullivan, Steven A -- Yamamoto, Marcio M -- Hoffman, Stephen L -- Wortman, Jennifer R -- Gardner, Malcolm J -- Galinski, Mary R -- Barnwell, John W -- Fraser-Liggett, Claire M -- N01 AI030071/AI/NIAID NIH HHS/ -- R01 AI064478/AI/NIAID NIH HHS/ -- R01 AI064478-05/AI/NIAID NIH HHS/ -- R01 GM070793/GM/NIGMS NIH HHS/ -- R01 GM070793-01A2/GM/NIGMS NIH HHS/ -- R01 GM083873/GM/NIGMS NIH HHS/ -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-09/LM/NLM NIH HHS/ -- England -- Nature. 2008 Oct 9;455(7214):757-63. doi: 10.1038/nature07327.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research/J.

    Description: Direct inhibition of transcription factor complexes remains a central challenge in the discipline of ligand discovery. In general, these proteins lack surface involutions suitable for high-affinity binding by small molecules. Here we report the design of synthetic, cell-permeable, stabilized alpha-helical peptides that target a critical protein-protein interface in the NOTCH transactivation complex. We demonstrate that direct, high-affinity binding of the hydrocarbon-stapled peptide SAHM1 prevents assembly of the active transcriptional complex. Inappropriate NOTCH activation is directly implicated in the pathogenesis of several disease states, including T-cell acute lymphoblastic leukaemia (T-ALL). The treatment of leukaemic cells with SAHM1 results in genome-wide suppression of NOTCH-activated genes. Direct antagonism of the NOTCH transcriptional program causes potent, NOTCH-specific anti-proliferative effects in cultured cells and in a mouse model of NOTCH1-driven T-ALL.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2951323/" 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/PMC2951323/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moellering, Raymond E -- Cornejo, Melanie -- Davis, Tina N -- Del Bianco, Cristina -- Aster, Jon C -- Blacklow, Stephen C -- Kung, Andrew L -- Gilliland, D Gary -- Verdine, Gregory L -- Bradner, James E -- 5T32GM007598/GM/NIGMS NIH HHS/ -- N01-CO-12400/CO/NCI NIH HHS/ -- P01 CA119070/CA/NCI NIH HHS/ -- P01 CA119070-049001/CA/NCI NIH HHS/ -- R01 CA092433/CA/NCI NIH HHS/ -- R01 CA092433-06A2/CA/NCI NIH HHS/ -- R56 CA092433/CA/NCI NIH HHS/ -- R56 CA092433-06A1/CA/NCI NIH HHS/ -- T32 GM007598/GM/NIGMS NIH HHS/ -- T32 GM007598-30/GM/NIGMS NIH HHS/ -- England -- Nature. 2009 Nov 12;462(7270):182-8. doi: 10.1038/nature08543.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry & Chemical Biology, Harvard University, Cambridge, Massachusetts 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19907488" target="_blank"〉PubMed〈/a〉

    Description: Locomotion relies on neural networks called central pattern generators (CPGs) that generate periodic motor commands for rhythmic movements. In vertebrates, the excitatory synaptic drive for inducing the spinal CPG can originate from either supraspinal glutamatergic inputs or from within the spinal cord. Here we identify a spinal input to the CPG that drives spontaneous locomotion using a combination of intersectional gene expression and optogenetics in zebrafish larvae. The photo-stimulation of one specific cell type was sufficient to induce a symmetrical tail beating sequence that mimics spontaneous slow forward swimming. This neuron is the Kolmer-Agduhr cell, which extends cilia into the central cerebrospinal-fluid-containing canal of the spinal cord and has an ipsilateral ascending axon that terminates in a series of consecutive segments. Genetically silencing Kolmer-Agduhr cells reduced the frequency of spontaneous free swimming, indicating that activity of Kolmer-Agduhr cells provides necessary tone for spontaneous forward swimming. Kolmer-Agduhr cells have been known for over 75 years, but their function has been mysterious. Our results reveal that during early development in zebrafish these cells provide a positive drive to the spinal CPG for spontaneous locomotion.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2770190/" 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/PMC2770190/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wyart, Claire -- Del Bene, Filippo -- Warp, Erica -- Scott, Ethan K -- Trauner, Dirk -- Baier, Herwig -- Isacoff, Ehud Y -- 5PN2EY018241/EY/NEI NIH HHS/ -- R01 NS035549/NS/NINDS NIH HHS/ -- R01 NS035549-12/NS/NINDS NIH HHS/ -- R01 NS053358/NS/NINDS NIH HHS/ -- England -- Nature. 2009 Sep 17;461(7262):407-10. doi: 10.1038/nature08323.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Helen Wills Neuroscience Institute and Department of Molecular and Cell Biology, University of California in Berkeley, Berkeley, California 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19759620" target="_blank"〉PubMed〈/a〉

    Description: Animals clearly choose what they eat and can even choose among chemically different sugars. The physiological and biochemical mechanisms that constrain feeding choices are largely unknown. In this study, European starlings (Sturnus vulgaris) preferred mixture solutions of D-glucose plus D-fructose to equimolar (double molar caloric value) solutions of sucrose. Intubation feeding of sucrose did not increase blood glucose levels. Sucrose is a useless energy source for these birds because they lack a single digestive enzyme (sucrase) on the small intestinal brush border membrane. However, the membranes possessed separate maltase and isomaltase disaccharidases. This expression pattern and expression patterns of membrane disaccharidases among mammals suggest a role for intestinal enzymes in the coevolutionary interactions between vertebrates and their plant food sources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martinez del Rio, C -- Stevens, B R -- DK-38715/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 10;243(4892):794-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Florida, Gainesville 32611.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2916126" target="_blank"〉PubMed〈/a〉

    Description: The 66-kilodalton isoform of the growth factor adapter Shc (p66Shc) translates oxidative damage into cell death by acting as reactive oxygen species (ROS) producer within mitochondria. However, the signaling link between cellular stress and mitochondrial proapoptotic activity of p66Shc was not known. We demonstrate that protein kinase C beta, activated by oxidative conditions in the cell, induces phosphorylation of p66Shc and triggers mitochondrial accumulation of the protein after it is recognized by the prolyl isomerase Pin1. Once imported, p66Shc causes alterations of mitochondrial Ca2+ responses and three-dimensional structure, thus inducing apoptosis. These data identify a signaling route that activates an apoptotic inducer shortening the life span and could be a potential target of pharmacological approaches to inhibit aging.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pinton, Paolo -- Rimessi, Alessandro -- Marchi, Saverio -- Orsini, Francesca -- Migliaccio, Enrica -- Giorgio, Marco -- Contursi, Cristina -- Minucci, Saverio -- Mantovani, Fiamma -- Wieckowski, Mariusz R -- Del Sal, Giannino -- Pelicci, Pier Giuseppe -- Rizzuto, Rosario -- GGP05284/Telethon/Italy -- New York, N.Y. -- Science. 2007 Feb 2;315(5812):659-63.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental and Diagnostic Medicine, Section of General Pathology and Interdisciplinary Center for the Study of Inflammation (ICSI), University of Ferrara, Ferrera, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17272725" target="_blank"〉PubMed〈/a〉

    Description: Antibody class switching in activated B cells uses class switch recombination (CSR), which joins activation-induced cytidine deaminase (AID)-dependent double-strand breaks (DSBs) within two large immunoglobulin heavy chain (IgH) locus switch (S) regions that lie up to 200 kilobases apart. To test postulated roles of S regions and AID in CSR, we generated mutant B cells in which donor Smu and accepter Sgamma1 regions were replaced with yeast I-SceI endonuclease sites. We found that site-specific I-SceI DSBs mediate recombinational IgH locus class switching from IgM to IgG1 without S regions or AID. We propose that CSR evolved to exploit a general DNA repair process that promotes joining of widely separated DSBs within a chromosome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zarrin, Ali A -- Del Vecchio, Catherine -- Tseng, Eva -- Gleason, Megan -- Zarin, Payam -- Tian, Ming -- Alt, Frederick W -- 2P01AI031541-15/AI/NIAID NIH HHS/ -- P01CA092625-05/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2007 Jan 19;315(5810):377-81.

    Description: The molecular mechanism by which a mechanical stimulus is translated into a chemical response in biological systems is still unclear. We show that mechanical stretching of single cytoplasmic proteins can activate binding of other molecules. We used magnetic tweezers, total internal reflection fluorescence, and atomic force microscopy to investigate the effect of force on the interaction between talin, a protein that links liganded membrane integrins to the cytoskeleton, and vinculin, a focal adhesion protein that is activated by talin binding, leading to reorganization of the cytoskeleton. Application of physiologically relevant forces caused stretching of single talin rods that exposed cryptic binding sites for vinculin. Thus in the talin-vinculin system, molecular mechanotransduction can occur by protein binding after exposure of buried binding sites in the talin-vinculin system. Such protein stretching may be a more general mechanism for force transduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉del Rio, Armando -- Perez-Jimenez, Raul -- Liu, Ruchuan -- Roca-Cusachs, Pere -- Fernandez, Julio M -- Sheetz, Michael P -- New York, N.Y. -- Science. 2009 Jan 30;323(5914):638-41. doi: 10.1126/science.1162912.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Columbia University, New York, NY 10027, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19179532" target="_blank"〉PubMed〈/a〉

    Description: Telomerase activity controls telomere length and plays a pivotal role in stem cells, aging, and cancer. Here, we report a molecular link between Wnt/beta-catenin signaling and the expression of the telomerase subunit Tert. beta-Catenin-deficient mouse embryonic stem (ES) cells have short telomeres; conversely, ES cell expressing an activated form of beta-catenin (beta-cat(DeltaEx3/+)) have long telomeres. We show that beta-catenin regulates Tert expression through the interaction with Klf4, a core component of the pluripotency transcriptional network. beta-Catenin binds to the Tert promoter in a mouse intestinal tumor model and in human carcinoma cells. We uncover a previously unknown link between the stem cell and oncogenic potential whereby beta-catenin regulates Tert expression, and thereby telomere length, which could be critical in human regenerative therapy and cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffmeyer, Katrin -- Raggioli, Angelo -- Rudloff, Stefan -- Anton, Roman -- Hierholzer, Andreas -- Del Valle, Ignacio -- Hein, Kerstin -- Vogt, Riana -- Kemler, Rolf -- New York, N.Y. -- Science. 2012 Jun 22;336(6088):1549-54. doi: 10.1126/science.1218370.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Embryology, Max Planck Institute of Immunobiology and Epigenetics, Freiburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22723415" target="_blank"〉PubMed〈/a〉
