    Description: The final identity and functional properties of a neuron are specified by terminal differentiation genes, which are controlled by specific motifs in compact regulatory regions. To determine how these sequences integrate inputs from transcription factors that specify cell types, we compared the regulatory mechanism of Drosophila Rhodopsin genes that are expressed in subsets of photoreceptors to that of phototransduction genes that are expressed broadly, in all photoreceptors. Both sets of genes share an 11-base pair (bp) activator motif. Broadly expressed genes contain a palindromic version that mediates expression in all photoreceptors. In contrast, each Rhodopsin exhibits characteristic single-bp substitutions that break the symmetry of the palindrome and generate activator or repressor motifs critical for restricting expression to photoreceptor subsets. Sensory neuron subtypes can therefore evolve through single-bp changes in short regulatory motifs, allowing the discrimination of a wide spectrum of stimuli.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rister, Jens -- Razzaq, Ansa -- Boodram, Pamela -- Desai, Nisha -- Tsanis, Cleopatra -- Chen, Hongtao -- Jukam, David -- Desplan, Claude -- K99EY023995/EY/NEI NIH HHS/ -- R01 EY13010/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2015 Dec 4;350(6265):1258-61. doi: 10.1126/science.aab3417.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Developmental Genetics, Department of Biology, New York University, 100 Washington Square East, New York, NY 10003-6688, USA. ; Center for Developmental Genetics, Department of Biology, New York University, 100 Washington Square East, New York, NY 10003-6688, USA. cd38@nyu.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26785491" target="_blank"〉PubMed〈/a〉

    Description: Congenital heart disease (CHD) patients have an increased prevalence of extracardiac congenital anomalies (CAs) and risk of neurodevelopmental disabilities (NDDs). Exome sequencing of 1213 CHD parent-offspring trios identified an excess of protein-damaging de novo mutations, especially in genes highly expressed in the developing heart and brain. These mutations accounted for 20% of patients with CHD, NDD, and CA but only 2% of patients with isolated CHD. Mutations altered genes involved in morphogenesis, chromatin modification, and transcriptional regulation, including multiple mutations in RBFOX2, a regulator of mRNA splicing. Genes mutated in other cohorts examined for NDD were enriched in CHD cases, particularly those with coexisting NDD. These findings reveal shared genetic contributions to CHD, NDD, and CA and provide opportunities for improved prognostic assessment and early therapeutic intervention in CHD patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Homsy, Jason -- Zaidi, Samir -- Shen, Yufeng -- Ware, James S -- Samocha, Kaitlin E -- Karczewski, Konrad J -- DePalma, Steven R -- McKean, David -- Wakimoto, Hiroko -- Gorham, Josh -- Jin, Sheng Chih -- Deanfield, John -- Giardini, Alessandro -- Porter, George A Jr -- Kim, Richard -- Bilguvar, Kaya -- Lopez-Giraldez, Francesc -- Tikhonova, Irina -- Mane, Shrikant -- Romano-Adesman, Angela -- Qi, Hongjian -- Vardarajan, Badri -- Ma, Lijiang -- Daly, Mark -- Roberts, Amy E -- Russell, Mark W -- Mital, Seema -- Newburger, Jane W -- Gaynor, J William -- Breitbart, Roger E -- Iossifov, Ivan -- Ronemus, Michael -- Sanders, Stephan J -- Kaltman, Jonathan R -- Seidman, Jonathan G -- Brueckner, Martina -- Gelb, Bruce D -- Goldmuntz, Elizabeth -- Lifton, Richard P -- Seidman, Christine E -- Chung, Wendy K -- T32 HL007208/HL/NHLBI NIH HHS/ -- Arthritis Research UK/United Kingdom -- British Heart Foundation/United Kingdom -- Department of Health/United Kingdom -- Howard Hughes Medical Institute/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Dec 4;350(6265):1262-6. doi: 10.1126/science.aac9396.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Boston, MA, USA.

    Description: Research into stem cells and aging aims to understand how stem cells maintain tissue health, what mechanisms ultimately lead to decline in stem cell function with age, and how the regenerative capacity of somatic stem cells can be enhanced to promote healthy aging. Here, we explore the effects of aging on stem cells in different tissues. Recent research has focused on the ways that genetic mutations, epigenetic changes, and the extrinsic environmental milieu influence stem cell functionality over time. We describe each of these three factors, the ways in which they interact, and how these interactions decrease stem cell health over time. We are optimistic that a better understanding of these changes will uncover potential strategies to enhance stem cell function and increase tissue resiliency into old age.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goodell, Margaret A -- Rando, Thomas A -- P01 AG036695/AG/NIA NIH HHS/ -- R01 AG047820/AG/NIA NIH HHS/ -- R01 AR062185/AR/NIAMS NIH HHS/ -- R37 AG023806/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2015 Dec 4;350(6265):1199-204. doi: 10.1126/science.aab3388.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Stem Cells and Regenerative Medicine Center, Center for Cell and Gene Therapy, and Department of Pediatrics, Baylor College of Medicine, Houston, TX 77030, USA. goodell@bcm.edu rando@stanford.edu. ; Glenn Center for the Biology of Aging and Department of Neurology and Neurological Sciences, Stanford University School of Medicine, Stanford, CA 94305, USA, and Center for Regenerative Rehabilitation, Veterans Administration Palo Alto Health Care System, Palo Alto, CA 94304, USA. goodell@bcm.edu rando@stanford.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26785478" target="_blank"〉PubMed〈/a〉

    Description: Hundreds of pathways for degradation converge at ubiquitin recognition by a proteasome. Here, we found that the five known proteasomal ubiquitin receptors in yeast are collectively nonessential for ubiquitin recognition and identified a sixth receptor, Rpn1. A site ( T1: ) in the Rpn1 toroid recognized ubiquitin and ubiquitin-like ( UBL: ) domains of substrate shuttling factors. T1 structures with monoubiquitin or lysine 48 diubiquitin show three neighboring outer helices engaging two ubiquitins. T1 contributes a distinct substrate-binding pathway with preference for lysine 48-linked chains. Proximal to T1 within the Rpn1 toroid is a second UBL-binding site ( T2: ) that assists in ubiquitin chain disassembly, by binding the UBL of deubiquitinating enzyme Ubp6. Thus, a two-site recognition domain intrinsic to the proteasome uses distinct ubiquitin-fold ligands to assemble substrates, shuttling factors, and a deubiquitinating enzyme.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shi, Yuan -- Chen, Xiang -- Elsasser, Suzanne -- Stocks, Bradley B -- Tian, Geng -- Lee, Byung-Hoon -- Shi, Yanhong -- Zhang, Naixia -- de Poot, Stefanie A H -- Tuebing, Fabian -- Sun, Shuangwu -- Vannoy, Jacob -- Tarasov, Sergey G -- Engen, John R -- Finley, Daniel -- Walters, Kylie J -- New York, N.Y. -- Science. 2016 Feb 19;351(6275). pii: aad9421. doi: 10.1126/science.aad9421.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, 240 Longwood Avenue, Boston, MA 02115, USA. ; Protein Processing Section, Structural Biophysics Laboratory, Center for Cancer Research, National Cancer Institute, Frederick, MD 21702, USA. ; Department of Chemistry and Chemical Biology, Northeastern University, Boston, MA 02115, USA. ; Protein Processing Section, Structural Biophysics Laboratory, Center for Cancer Research, National Cancer Institute, Frederick, MD 21702, USA.

    Description: As tumors grow, they acquire mutations, some of which create neoantigens that influence the response of patients to immune checkpoint inhibitors. We explored the impact of neoantigen intratumor heterogeneity (ITH) on antitumor immunity. Through integrated analysis of ITH and neoantigen burden, we demonstrate a relationship between clonal neoantigen burden and overall survival in primary lung adenocarcinomas. CD8(+)tumor-infiltrating lymphocytes reactive to clonal neoantigens were identified in early-stage non-small cell lung cancer and expressed high levels of PD-1. Sensitivity to PD-1 and CTLA-4 blockade in patients with advanced NSCLC and melanoma was enhanced in tumors enriched for clonal neoantigens. T cells recognizing clonal neoantigens were detectable in patients with durable clinical benefit. Cytotoxic chemotherapy-induced subclonal neoantigens, contributing to an increased mutational load, were enriched in certain poor responders. These data suggest that neoantigen heterogeneity may influence immune surveillance and support therapeutic developments targeting clonal neoantigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGranahan, Nicholas -- Furness, Andrew J S -- Rosenthal, Rachel -- Ramskov, Sofie -- Lyngaa, Rikke -- Saini, Sunil Kumar -- Jamal-Hanjani, Mariam -- Wilson, Gareth A -- Birkbak, Nicolai J -- Hiley, Crispin T -- Watkins, Thomas B K -- Shafi, Seema -- Murugaesu, Nirupa -- Mitter, Richard -- Akarca, Ayse U -- Linares, Joseph -- Marafioti, Teresa -- Henry, Jake Y -- Van Allen, Eliezer M -- Miao, Diana -- Schilling, Bastian -- Schadendorf, Dirk -- Garraway, Levi A -- Makarov, Vladimir -- Rizvi, Naiyer A -- Snyder, Alexandra -- Hellmann, Matthew D -- Merghoub, Taha -- Wolchok, Jedd D -- Shukla, Sachet A -- Wu, Catherine J -- Peggs, Karl S -- Chan, Timothy A -- Hadrup, Sine R -- Quezada, Sergio A -- Swanton, Charles -- 12100/Cancer Research UK/United Kingdom -- 1R01CA155010-02/CA/NCI NIH HHS/ -- 1R01CA182461-01/CA/NCI NIH HHS/ -- 1R01CA184922-01/CA/NCI NIH HHS/ -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1463-9. doi: 10.1126/science.aaf1490.

    Description: Brazil has experienced an unprecedented epidemic of Zika virus (ZIKV), with ~30,000 cases reported to date. ZIKV was first detected in Brazil in May 2015, and cases of microcephaly potentially associated with ZIKV infection were identified in November 2015. We performed next-generation sequencing to generate seven Brazilian ZIKV genomes sampled from four self-limited cases, one blood donor, one fatal adult case, and one newborn with microcephaly and congenital malformations. Results of phylogenetic and molecular clock analyses show a single introduction of ZIKV into the Americas, which we estimated to have occurred between May and December 2013, more than 12 months before the detection of ZIKV in Brazil. The estimated date of origin coincides with an increase in air passengers to Brazil from ZIKV-endemic areas, as well as with reported outbreaks in the Pacific Islands. ZIKV genomes from Brazil are phylogenetically interspersed with those from other South American and Caribbean countries. Mapping mutations onto existing structural models revealed the context of viral amino acid changes present in the outbreak lineage; however, no shared amino acid changes were found among the three currently available virus genomes from microcephaly cases. Municipality-level incidence data indicate that reports of suspected microcephaly in Brazil best correlate with ZIKV incidence around week 17 of pregnancy, although this correlation does not demonstrate causation. Our genetic description and analysis of ZIKV isolates in Brazil provide a baseline for future studies of the evolution and molecular epidemiology of this emerging virus in the Americas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faria, Nuno Rodrigues -- Azevedo, Raimunda do Socorro da Silva -- Kraemer, Moritz U G -- Souza, Renato -- Cunha, Mariana Sequetin -- Hill, Sarah C -- Theze, Julien -- Bonsall, Michael B -- Bowden, Thomas A -- Rissanen, Ilona -- Rocco, Iray Maria -- Nogueira, Juliana Silva -- Maeda, Adriana Yurika -- Vasami, Fernanda Giseli da Silva -- Macedo, Fernando Luiz de Lima -- Suzuki, Akemi -- Rodrigues, Sueli Guerreiro -- Cruz, Ana Cecilia Ribeiro -- Nunes, Bruno Tardeli -- Medeiros, Daniele Barbosa de Almeida -- Rodrigues, Daniela Sueli Guerreiro -- Nunes Queiroz, Alice Louize -- da Silva, Eliana Vieira Pinto -- Henriques, Daniele Freitas -- Travassos da Rosa, Elisabeth Salbe -- de Oliveira, Consuelo Silva -- Martins, Livia Caricio -- Vasconcelos, Helena Baldez -- Casseb, Livia Medeiros Neves -- Simith, Darlene de Brito -- Messina, Jane P -- Abade, Leandro -- Lourenco, Jose -- Carlos Junior Alcantara, Luiz -- de Lima, Maricelia Maia -- Giovanetti, Marta -- Hay, Simon I -- de Oliveira, Rodrigo Santos -- Lemos, Poliana da Silva -- de Oliveira, Layanna Freitas -- de Lima, Clayton Pereira Silva -- da Silva, Sandro Patroca -- de Vasconcelos, Janaina Mota -- Franco, Luciano -- Cardoso, Jedson Ferreira -- Vianez-Junior, Joao Lidio da Silva Goncalves -- Mir, Daiana -- Bello, Gonzalo -- Delatorre, Edson -- Khan, Kamran -- Creatore, Marisa -- Coelho, Giovanini Evelim -- de Oliveira, Wanderson Kleber -- Tesh, Robert -- Pybus, Oliver G -- Nunes, Marcio R T -- Vasconcelos, Pedro F C -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 095066/Wellcome Trust/United Kingdom -- 102427/Wellcome Trust/United Kingdom -- MR/L009528/1/Medical Research Council/United Kingdom -- R24 AT 120942/AT/NCCIH NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):345-9. doi: 10.1126/science.aaf5036.

    Description: Drug resistance compromises control of malaria. Here, we show that resistance to a commonly used antimalarial medication, atovaquone, is apparently unable to spread. Atovaquone pressure selects parasites with mutations in cytochrome b, a respiratory protein with low but essential activity in the mammalian blood phase of the parasite life cycle. Resistance mutations rescue parasites from the drug but later prove lethal in the mosquito phase, where parasites require full respiration. Unable to respire efficiently, resistant parasites fail to complete mosquito development, arresting their life cycle. Because cytochrome b is encoded by the maternally inherited parasite mitochondrion, even outcrossing with wild-type strains cannot facilitate spread of resistance. Lack of transmission suggests that resistance will be unable to spread in the field, greatly enhancing the utility of atovaquone in malaria control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goodman, Christopher D -- Siregar, Josephine E -- Mollard, Vanessa -- Vega-Rodriguez, Joel -- Syafruddin, Din -- Matsuoka, Hiroyuki -- Matsuzaki, Motomichi -- Toyama, Tomoko -- Sturm, Angelika -- Cozijnsen, Anton -- Jacobs-Lorena, Marcelo -- Kita, Kiyoshi -- Marzuki, Sangkot -- McFadden, Geoffrey I -- AI031478/AI/NIAID NIH HHS/ -- RR00052/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2016 Apr 15;352(6283):349-53. doi: 10.1126/science.aad9279.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of BioSciences, University of Melbourne, Melbourne, VIC 3010, Australia. gim@unimelb.edu.au deang@unimelb.edu.au. ; School of BioSciences, University of Melbourne, Melbourne, VIC 3010, Australia.

    Description: Oncogenes are activated through well-known chromosomal alterations such as gene fusion, translocation, and focal amplification. In light of recent evidence that the control of key genes depends on chromosome structures called insulated neighborhoods, we investigated whether proto-oncogenes occur within these structures and whether oncogene activation can occur via disruption of insulated neighborhood boundaries in cancer cells. We mapped insulated neighborhoods in T cell acute lymphoblastic leukemia (T-ALL) and found that tumor cell genomes contain recurrent microdeletions that eliminate the boundary sites of insulated neighborhoods containing prominent T-ALL proto-oncogenes. Perturbation of such boundaries in nonmalignant cells was sufficient to activate proto-oncogenes. Mutations affecting chromosome neighborhood boundaries were found in many types of cancer. Thus, oncogene activation can occur via genetic alterations that disrupt insulated neighborhoods in malignant cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hnisz, Denes -- Weintraub, Abraham S -- Day, Daniel S -- Valton, Anne-Laure -- Bak, Rasmus O -- Li, Charles H -- Goldmann, Johanna -- Lajoie, Bryan R -- Fan, Zi Peng -- Sigova, Alla A -- Reddy, Jessica -- Borges-Rivera, Diego -- Lee, Tong Ihn -- Jaenisch, Rudolf -- Porteus, Matthew H -- Dekker, Job -- Young, Richard A -- AI120766/AI/NIAID NIH HHS/ -- CA109901/CA/NCI NIH HHS/ -- HG002668/HG/NHGRI NIH HHS/ -- MH104610/MH/NIMH NIH HHS/ -- NS088538/NS/NINDS NIH HHS/ -- R01 GM 112720/GM/NIGMS NIH HHS/ -- R01 HG002668/HG/NHGRI NIH HHS/ -- R01 HG003143/HG/NHGRI NIH HHS/ -- R01 MH104610/MH/NIMH NIH HHS/ -- U01 DA 040588/DA/NIDA NIH HHS/ -- U01 HG007910/HG/NHGRI NIH HHS/ -- U01 R01 AI 117839/AI/NIAID NIH HHS/ -- U54 CA193419/CA/NCI NIH HHS/ -- U54 DK107980/DK/NIDDK NIH HHS/ -- U54 HG007010/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1454-8. doi: 10.1126/science.aad9024.

    Description: Sequencing of exomes and genomes has revealed abundant genetic variation affecting the coding sequences of human transcription factors (TFs), but the consequences of such variation remain largely unexplored. We developed a computational, structure-based approach to evaluate TF variants for their impact on DNA binding activity and used universal protein-binding microarrays to assay sequence-specific DNA binding activity across 41 reference and 117 variant alleles found in individuals of diverse ancestries and families with Mendelian diseases. We found 77 variants in 28 genes that affect DNA binding affinity or specificity and identified thousands of rare alleles likely to alter the DNA binding activity of human sequence-specific TFs. Our results suggest that most individuals have unique repertoires of TF DNA binding activities, which may contribute to phenotypic variation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4825693/" 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/PMC4825693/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barrera, Luis A -- Vedenko, Anastasia -- Kurland, Jesse V -- Rogers, Julia M -- Gisselbrecht, Stephen S -- Rossin, Elizabeth J -- Woodard, Jaie -- Mariani, Luca -- Kock, Kian Hong -- Inukai, Sachi -- Siggers, Trevor -- Shokri, Leila -- Gordan, Raluca -- Sahni, Nidhi -- Cotsapas, Chris -- Hao, Tong -- Yi, Song -- Kellis, Manolis -- Daly, Mark J -- Vidal, Marc -- Hill, David E -- Bulyk, Martha L -- P50 HG004233/HG/NHGRI NIH HHS/ -- R01 HG003985/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1450-4. doi: 10.1126/science.aad2257.

    Description: Antibiotic treatment has two conflicting effects: the desired, immediate effect of inhibiting bacterial growth and the undesired, long-term effect of promoting the evolution of resistance. Although these contrasting outcomes seem inextricably linked, recent work has revealed several ways by which antibiotics can be combined to inhibit bacterial growth while, counterintuitively, selecting against resistant mutants. Decoupling treatment efficacy from the risk of resistance can be achieved by exploiting specific interactions between drugs, and the ways in which resistance mutations to a given drug can modulate these interactions or increase the sensitivity of the bacteria to other compounds. Although their practical application requires much further development and validation, and relies on advances in genomic diagnostics, these discoveries suggest novel paradigms that may restrict or even reverse the evolution of resistance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baym, Michael -- Stone, Laura K -- Kishony, Roy -- R01-GM081617/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2016 Jan 1;351(6268):aad3292. doi: 10.1126/science.aad3292.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Systems Biology, Harvard Medical School, Boston, MA, USA. ; Department of Systems Biology, Harvard Medical School, Boston, MA, USA.

    Description: Induction of broadly neutralizing antibodies (bnAbs) is a major HIV vaccine goal. Germline-targeting immunogens aim to initiate bnAb induction by activating bnAb germline precursor B cells. Critical unmet challenges are to determine whether bnAb precursor naive B cells bind germline-targeting immunogens and occur at sufficient frequency in humans for reliable vaccine responses. Using deep mutational scanning and multitarget optimization, we developed a germline-targeting immunogen (eOD-GT8) for diverse VRC01-class bnAbs. We then used the immunogen to isolate VRC01-class precursor naive B cells from HIV-uninfected donors. Frequencies of true VRC01-class precursors, their structures, and their eOD-GT8 affinities support this immunogen as a candidate human vaccine prime. These methods could be applied to germline targeting for other classes of HIV bnAbs and for Abs to other pathogens.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4872700/" 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/PMC4872700/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jardine, Joseph G -- Kulp, Daniel W -- Havenar-Daughton, Colin -- Sarkar, Anita -- Briney, Bryan -- Sok, Devin -- Sesterhenn, Fabian -- Ereno-Orbea, June -- Kalyuzhniy, Oleksandr -- Deresa, Isaiah -- Hu, Xiaozhen -- Spencer, Skye -- Jones, Meaghan -- Georgeson, Erik -- Adachi, Yumiko -- Kubitz, Michael -- deCamp, Allan C -- Julien, Jean-Philippe -- Wilson, Ian A -- Burton, Dennis R -- Crotty, Shane -- Schief, William R -- P01 AI094419/AI/NIAID NIH HHS/ -- P01 AI110657/AI/NIAID NIH HHS/ -- P41GM103393/GM/NIGMS NIH HHS/ -- R01 AI084817/AI/NIAID NIH HHS/ -- UM1 AI100663/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Mar 25;351(6280):1458-63. doi: 10.1126/science.aad9195.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology and Microbial Science, The Scripps Research Institute, La Jolla, CA 92037, USA.

    Description: The lung is constantly exposed to environmental atmospheric cues. How it senses and responds to these cues is poorly defined. Here, we show that Roundabout receptor (Robo) genes are expressed in pulmonary neuroendocrine cells (PNECs), a rare, innervated epithelial population. Robo inactivation in mouse lung results in an inability of PNECs to cluster into sensory organoids and triggers increased neuropeptide production upon exposure to air. Excess neuropeptides lead to an increase in immune infiltrates, which in turn remodel the matrix and irreversibly simplify the alveoli. We demonstrate in vivo that PNECs act as precise airway sensors that elicit immune responses via neuropeptides. These findings suggest that the PNEC and neuropeptide abnormalities documented in a wide array of pulmonary diseases may profoundly affect symptoms and progression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Branchfield, Kelsey -- Nantie, Leah -- Verheyden, Jamie M -- Sui, Pengfei -- Wienhold, Mark D -- Sun, Xin -- 5T32AI007635/AI/NIAID NIH HHS/ -- HL097134/HL/NHLBI NIH HHS/ -- HL122406/HL/NHLBI NIH HHS/ -- R01 HL113870/HL/NHLBI NIH HHS/ -- T32 GM007133/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2016 Feb 12;351(6274):707-10. doi: 10.1126/science.aad7969.

    Description: The "cancerized field" concept posits that cancer-prone cells in a given tissue share an oncogenic mutation, but only discreet clones within the field initiate tumors. Most benign nevi carry oncogenic BRAF(V600E) mutations but rarely become melanoma. The zebrafish crestin gene is expressed embryonically in neural crest progenitors (NCPs) and specifically reexpressed in melanoma. Live imaging of transgenic zebrafish crestin reporters shows that within a cancerized field (BRAF(V600E)-mutant; p53-deficient), a single melanocyte reactivates the NCP state, revealing a fate change at melanoma initiation in this model. NCP transcription factors, including sox10, regulate crestin expression. Forced sox10 overexpression in melanocytes accelerated melanoma formation, which is consistent with activation of NCP genes and super-enhancers leading to melanoma. Our work highlights NCP state reemergence as a key event in melanoma initiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaufman, Charles K -- Mosimann, Christian -- Fan, Zi Peng -- Yang, Song -- Thomas, Andrew J -- Ablain, Julien -- Tan, Justin L -- Fogley, Rachel D -- van Rooijen, Ellen -- Hagedorn, Elliott J -- Ciarlo, Christie -- White, Richard M -- Matos, Dominick A -- Puller, Ann-Christin -- Santoriello, Cristina -- Liao, Eric C -- Young, Richard A -- Zon, Leonard I -- HG002668/HG/NHGRI NIH HHS/ -- K08 AR061071/AR/NIAMS NIH HHS/ -- R01 CA103846/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Jan 29;351(6272):aad2197. doi: 10.1126/science.aad2197.

    Description: Type IVa pili are filamentous cell surface structures observed in many bacteria. They pull cells forward by extending, adhering to surfaces, and then retracting. We used cryo-electron tomography of intact Myxococcus xanthus cells to visualize type IVa pili and the protein machine that assembles and retracts them (the type IVa pilus machine, or T4PM) in situ, in both the piliated and nonpiliated states, at a resolution of 3 to 4 nanometers. We found that T4PM comprises an outer membrane pore, four interconnected ring structures in the periplasm and cytoplasm, a cytoplasmic disc and dome, and a periplasmic stem. By systematically imaging mutants lacking defined T4PM proteins or with individual proteins fused to tags, we mapped the locations of all 10 T4PM core components and the minor pilins, thereby providing insights into pilus assembly, structure, and function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, Yi-Wei -- Rettberg, Lee A -- Treuner-Lange, Anke -- Iwasa, Janet -- Sogaard-Andersen, Lotte -- Jensen, Grant J -- R01 GM094800B/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):aad2001. doi: 10.1126/science.aad2001.

    Description: Plant immunity against foreign gene invasion takes advantage of posttranscriptional gene silencing (PTGS). How plants elaborately avert inappropriate PTGS of endogenous coding genes remains unclear. We demonstrate in Arabidopsis that both 5'-3' and 3'-5' cytoplasmic RNA decay pathways act as repressors of transgene and endogenous PTGS. Disruption of bidirectional cytoplasmic RNA decay leads to pleiotropic developmental defects and drastic transcriptomic alterations, which are substantially rescued by PTGS mutants. Upon dysfunction of bidirectional RNA decay, a large number of 21- to 22-nucleotide endogenous small interfering RNAs are produced from coding transcripts, including multiple microRNA targets, which could interfere with their cognate gene expression and functions. This study highlights the risk of unwanted PTGS and identifies cytoplasmic RNA decay pathways as safeguards of plant transcriptome and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Xinyan -- Zhu, Ying -- Liu, Xiaodan -- Hong, Xinyu -- Xu, Yang -- Zhu, Ping -- Shen, Yang -- Wu, Huihui -- Ji, Yusi -- Wen, Xing -- Zhang, Chen -- Zhao, Qiong -- Wang, Yichuan -- Lu, Jian -- Guo, Hongwei -- New York, N.Y. -- Science. 2015 Apr 3;348(6230):120-3. doi: 10.1126/science.aaa2618.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Protein and Plant Gene Research, College of Life Sciences, Peking University, Beijing 100871, China. ; Biodynamic Optical Imaging Center, School of Life Sciences, Peking University, Beijing 100871, China. ; Peking-Tsinghua Center for Life Sciences, Peking University, Beijing 100871, China. ; State Key Laboratory of Protein and Plant Gene Research, College of Life Sciences, Peking University, Beijing 100871, China.

    Description: Although the genes essential for life have been identified in less complex model organisms, their elucidation in human cells has been hindered by technical barriers. We used extensive mutagenesis in haploid human cells to identify approximately 2000 genes required for optimal fitness under culture conditions. To study the principles of genetic interactions in human cells, we created a synthetic lethality network focused on the secretory pathway based exclusively on mutations. This revealed a genetic cross-talk governing Golgi homeostasis, an additional subunit of the human oligosaccharyltransferase complex, and a phosphatidylinositol 4-kinase beta adaptor hijacked by viruses. The synthetic lethality map parallels observations made in yeast and projects a route forward to reveal genetic networks in diverse aspects of human cell biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blomen, Vincent A -- Majek, Peter -- Jae, Lucas T -- Bigenzahn, Johannes W -- Nieuwenhuis, Joppe -- Staring, Jacqueline -- Sacco, Roberto -- van Diemen, Ferdy R -- Olk, Nadine -- Stukalov, Alexey -- Marceau, Caleb -- Janssen, Hans -- Carette, Jan E -- Bennett, Keiryn L -- Colinge, Jacques -- Superti-Furga, Giulio -- Brummelkamp, Thijn R -- New York, N.Y. -- Science. 2015 Nov 27;350(6264):1092-6. doi: 10.1126/science.aac7557.

    Description: Immune checkpoint inhibitors, which unleash a patient's own T cells to kill tumors, are revolutionizing cancer treatment. To unravel the genomic determinants of response to this therapy, we used whole-exome sequencing of non-small cell lung cancers treated with pembrolizumab, an antibody targeting programmed cell death-1 (PD-1). In two independent cohorts, higher nonsynonymous mutation burden in tumors was associated with improved objective response, durable clinical benefit, and progression-free survival. Efficacy also correlated with the molecular smoking signature, higher neoantigen burden, and DNA repair pathway mutations; each factor was also associated with mutation burden. In one responder, neoantigen-specific CD8+ T cell responses paralleled tumor regression, suggesting that anti-PD-1 therapy enhances neoantigen-specific T cell reactivity. Our results suggest that the genomic landscape of lung cancers shapes response to anti-PD-1 therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rizvi, Naiyer A -- Hellmann, Matthew D -- Snyder, Alexandra -- Kvistborg, Pia -- Makarov, Vladimir -- Havel, Jonathan J -- Lee, William -- Yuan, Jianda -- Wong, Phillip -- Ho, Teresa S -- Miller, Martin L -- Rekhtman, Natasha -- Moreira, Andre L -- Ibrahim, Fawzia -- Bruggeman, Cameron -- Gasmi, Billel -- Zappasodi, Roberta -- Maeda, Yuka -- Sander, Chris -- Garon, Edward B -- Merghoub, Taha -- Wolchok, Jedd D -- Schumacher, Ton N -- Chan, Timothy A -- K23 CA149079/CA/NCI NIH HHS/ -- P30 CA008748/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Apr 3;348(6230):124-8. doi: 10.1126/science.aaa1348.

    Description: The function of neural circuits depends on the generation of specific classes of neurons. Neural identity is typically established near the time when neurons exit the cell cycle to become postmitotic cells, and it is generally accepted that, once the identity of a neuron has been established, its fate is maintained throughout life. Here, we show that network activity dynamically modulates the properties of fast-spiking (FS) interneurons through the postmitotic expression of the transcriptional regulator Er81. In the adult cortex, Er81 protein levels define a spectrum of FS basket cells with different properties, whose relative proportions are, however, continuously adjusted in response to neuronal activity. Our findings therefore suggest that interneuron properties are malleable in the adult cortex, at least to a certain extent.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4702376/" 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/PMC4702376/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dehorter, Nathalie -- Ciceri, Gabriele -- Bartolini, Giorgia -- Lim, Lynette -- del Pino, Isabel -- Marin, Oscar -- 103714MA/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Sep 11;349(6253):1216-20. doi: 10.1126/science.aab3415.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MRC Centre for Developmental Neurobiology, Medical Research Council, New Hunt's House, Guy's Campus, King's College London, London SE1 1UL, UK.

    Description: Adoptive cell therapy (ACT) is a highly personalized cancer therapy that involves administration to the cancer-bearing host of immune cells with direct anticancer activity. ACT using naturally occurring tumor-reactive lymphocytes has mediated durable, complete regressions in patients with melanoma, probably by targeting somatic mutations exclusive to each cancer.

    Description: Some tissue types give rise to human cancers millions of times more often than other tissue types. Although this has been recognized for more than a century, it has never been explained. Here, we show that the lifetime risk of cancers of many different types is strongly correlated (0.81) with the total number of divisions of the normal self-renewing cells maintaining that tissue's homeostasis. These results suggest that only a third of the variation in cancer risk among tissues is attributable to environmental factors or inherited predispositions. The majority is due to "bad luck," that is, random mutations arising during DNA replication in normal, noncancerous stem cells. This is important not only for understanding the disease but also for designing strategies to limit the mortality it causes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4446723/" 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/PMC4446723/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tomasetti, Cristian -- Vogelstein, Bert -- P30 CA006973/CA/NCI NIH HHS/ -- P30-CA006973/CA/NCI NIH HHS/ -- P50-CA62924/CA/NCI NIH HHS/ -- R01-CA57345/CA/NCI NIH HHS/ -- R37 CA043460/CA/NCI NIH HHS/ -- R37-CA43460/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jan 2;347(6217):78-81. doi: 10.1126/science.1260825.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biostatistics and Bioinformatics, Department of Oncology, Sidney Kimmel Cancer Center, Johns Hopkins University School of Medicine and Department of Biostatistics, Johns Hopkins Bloomberg School of Public Health, 550 North Broadway, Baltimore, MD 21205, USA. ctomasetti@jhu.edu vogelbe@jhmi.edu. ; Ludwig Center for Cancer Genetics and Therapeutics and Howard Hughes Medical Institute, Johns Hopkins Kimmel Cancer Center, 1650 Orleans Street, Baltimore, MD 21205, USA. ctomasetti@jhu.edu vogelbe@jhmi.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25554788" target="_blank"〉PubMed〈/a〉

    Description: It is unknown whether the human immune system frequently mounts a T cell response against mutations expressed by common epithelial cancers. Using a next-generation sequencing approach combined with high-throughput immunologic screening, we demonstrated that tumor-infiltrating lymphocytes (TILs) from 9 out of 10 patients with metastatic gastrointestinal cancers contained CD4(+) and/or CD8(+) T cells that recognized one to three neo-epitopes derived from somatic mutations expressed by the patient's own tumor. There were no immunogenic epitopes shared between these patients. However, we identified in one patient a human leukocyte antigen-C*08:02-restricted T cell receptor from CD8(+) TILs that targeted the KRAS(G12D) hotspot driver mutation found in many human cancers. Thus, a high frequency of patients with common gastrointestinal cancers harbor immunogenic mutations that can potentially be exploited for the development of highly personalized immunotherapies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tran, Eric -- Ahmadzadeh, Mojgan -- Lu, Yong-Chen -- Gros, Alena -- Turcotte, Simon -- Robbins, Paul F -- Gartner, Jared J -- Zheng, Zhili -- Li, Yong F -- Ray, Satyajit -- Wunderlich, John R -- Somerville, Robert P -- Rosenberg, Steven A -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2015 Dec 11;350(6266):1387-90. doi: 10.1126/science.aad1253.

    Description: Research in the genetics of neurodevelopmental disorders such as autism suggests that several hundred genes are likely risk factors for these disorders. This heterogeneity presents a challenge and an opportunity at the same time. Although the exact identity of many of the genes remains to be discovered, genes identified to date encode proteins that play roles in certain conserved pathways: protein synthesis, transcriptional and epigenetic regulation, and synaptic signaling. The next generation of research in neurodevelopmental disorders must address the neural circuitry underlying the behavioral symptoms and comorbidities, the cell types playing critical roles in these circuits, and common intercellular signaling pathways that link diverse genes. Results from clinical trials have been mixed so far. Only when we can leverage the heterogeneity of neurodevelopmental disorders into precision medicine will the mechanism-based therapeutics for these disorders start to unlock success.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4739545/" 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/PMC4739545/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sahin, Mustafa -- Sur, Mriganka -- EF1451125/PHS HHS/ -- EY007023/EY/NEI NIH HHS/ -- MH085802/MH/NIMH NIH HHS/ -- NS090473/NS/NINDS NIH HHS/ -- P20 NS080199/NS/NINDS NIH HHS/ -- P30 HD018655/HD/NICHD NIH HHS/ -- U01 NS082320/NS/NINDS NIH HHS/ -- U54 NS092090/NS/NINDS NIH HHS/ -- U54NS092090/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2015 Nov 20;350(6263). pii: aab3897. doi: 10.1126/science.aab3897.

    Description: Monoclonal antibodies directed against cytotoxic T lymphocyte-associated antigen-4 (CTLA-4), such as ipilimumab, yield considerable clinical benefit for patients with metastatic melanoma by inhibiting immune checkpoint activity, but clinical predictors of response to these therapies remain incompletely characterized. To investigate the roles of tumor-specific neoantigens and alterations in the tumor microenvironment in the response to ipilimumab, we analyzed whole exomes from pretreatment melanoma tumor biopsies and matching germline tissue samples from 110 patients. For 40 of these patients, we also obtained and analyzed transcriptome data from the pretreatment tumor samples. Overall mutational load, neoantigen load, and expression of cytolytic markers in the immune microenvironment were significantly associated with clinical benefit. However, no recurrent neoantigen peptide sequences predicted responder patient populations. Thus, detailed integrated molecular characterization of large patient cohorts may be needed to identify robust determinants of response and resistance to immune checkpoint inhibitors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van Allen, Eliezer M -- Miao, Diana -- Schilling, Bastian -- Shukla, Sachet A -- Blank, Christian -- Zimmer, Lisa -- Sucker, Antje -- Hillen, Uwe -- Foppen, Marnix H Geukes -- Goldinger, Simone M -- Utikal, Jochen -- Hassel, Jessica C -- Weide, Benjamin -- Kaehler, Katharina C -- Loquai, Carmen -- Mohr, Peter -- Gutzmer, Ralf -- Dummer, Reinhard -- Gabriel, Stacey -- Wu, Catherine J -- Schadendorf, Dirk -- Garraway, Levi A -- U54 HG003067/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2015 Oct 9;350(6257):207-11. doi: 10.1126/science.aad0095.

    Description: T cell immunity directed against tumor-encoded amino acid substitutions occurs in some melanoma patients. This implicates missense mutations as a source of patient-specific neoantigens. However, a systematic evaluation of these putative neoantigens as targets of antitumor immunity is lacking. Moreover, it remains unknown whether vaccination can augment such responses. We found that a dendritic cell vaccine led to an increase in naturally occurring neoantigen-specific immunity and revealed previously undetected human leukocyte antigen (HLA) class I-restricted neoantigens in patients with advanced melanoma. The presentation of neoantigens by HLA-A*02:01 in human melanoma was confirmed by mass spectrometry. Vaccination promoted a diverse neoantigen-specific T cell receptor (TCR) repertoire in terms of both TCR-beta usage and clonal composition. Our results demonstrate that vaccination directed at tumor-encoded amino acid substitutions broadens the antigenic breadth and clonal diversity of antitumor immunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4549796/" 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/PMC4549796/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carreno, Beatriz M -- Magrini, Vincent -- Becker-Hapak, Michelle -- Kaabinejadian, Saghar -- Hundal, Jasreet -- Petti, Allegra A -- Ly, Amy -- Lie, Wen-Rong -- Hildebrand, William H -- Mardis, Elaine R -- Linette, Gerald P -- 5U54HG00307/HG/NHGRI NIH HHS/ -- P30 CA091842/CA/NCI NIH HHS/ -- P30 CA91842/CA/NCI NIH HHS/ -- R21 CA179695/CA/NCI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2015 May 15;348(6236):803-8. doi: 10.1126/science.aaa3828.

    Description: The clinical relevance of T cells in the control of a diverse set of human cancers is now beyond doubt. However, the nature of the antigens that allow the immune system to distinguish cancer cells from noncancer cells has long remained obscure. Recent technological innovations have made it possible to dissect the immune response to patient-specific neoantigens that arise as a consequence of tumor-specific mutations, and emerging data suggest that recognition of such neoantigens is a major factor in the activity of clinical immunotherapies. These observations indicate that neoantigen load may form a biomarker in cancer immunotherapy and provide an incentive for the development of novel therapeutic approaches that selectively enhance T cell reactivity against this class of antigens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schumacher, Ton N -- Schreiber, Robert D -- R01CA04305926/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Apr 3;348(6230):69-74. doi: 10.1126/science.aaa4971.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Immunology, Netherlands Cancer Institute, Plesmanlaan 121, 1066 CX, Amsterdam, Netherlands. t.schumacher@nki.nl schreiber@immunology.wustl.edu. ; Department of Pathology and Immunology, Washington University School of Medicine, 660 South Euclid Avenue, St. Louis, MO 63110, USA. t.schumacher@nki.nl schreiber@immunology.wustl.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25838375" target="_blank"〉PubMed〈/a〉

    Description: Base-pairing interactions between nucleic acids mediate target recognition in many biological processes. We developed a super-resolution imaging and modeling platform that enabled the in vivo determination of base pairing-mediated target recognition kinetics. We examined a stress-induced bacterial small RNA, SgrS, which induces the degradation of target messenger RNAs (mRNAs). SgrS binds to a primary target mRNA in a reversible and dynamic fashion, and formation of SgrS-mRNA complexes is rate-limiting, dictating the overall regulation efficiency in vivo. Examination of a secondary target indicated that differences in the target search kinetics contribute to setting the regulation priority among different target mRNAs. This super-resolution imaging and analysis approach provides a conceptual framework that can be generalized to other small RNA systems and other target search processes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4410144/" 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/PMC4410144/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fei, Jingyi -- Singh, Digvijay -- Zhang, Qiucen -- Park, Seongjin -- Balasubramanian, Divya -- Golding, Ido -- Vanderpool, Carin K -- Ha, Taekjip -- GM 112659/GM/NIGMS NIH HHS/ -- GM065367/GM/NIGMS NIH HHS/ -- GM082837/GM/NIGMS NIH HHS/ -- GM092830/GM/NIGMS NIH HHS/ -- R01 GM065367/GM/NIGMS NIH HHS/ -- R01 GM082837/GM/NIGMS NIH HHS/ -- R01 GM092830/GM/NIGMS NIH HHS/ -- R01 GM112659/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Mar 20;347(6228):1371-4. doi: 10.1126/science.1258849.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for the Physics of Living Cells, Department of Physics, University of Illinois, Urbana, IL, USA. ; Center for Biophysics and Computational Biology, University of Illinois, Urbana, IL, USA. ; Department of Microbiology, University of Illinois, Urbana, IL, USA. ; Center for the Physics of Living Cells, Department of Physics, University of Illinois, Urbana, IL, USA.

    Description: Adenosine-to-inosine (A-to-I) editing is a highly prevalent posttranscriptional modification of RNA, mediated by ADAR (adenosine deaminase acting on RNA) enzymes. In addition to RNA editing, additional functions have been proposed for ADAR1. To determine the specific role of RNA editing by ADAR1, we generated mice with an editing-deficient knock-in mutation (Adar1(E861A), where E861A denotes Glu(861)--〉Ala(861)). Adar1(E861A/E861A) embryos died at ~E13.5 (embryonic day 13.5), with activated interferon and double-stranded RNA (dsRNA)-sensing pathways. Genome-wide analysis of the in vivo substrates of ADAR1 identified clustered hyperediting within long dsRNA stem loops within 3' untranslated regions of endogenous transcripts. Finally, embryonic death and phenotypes of Adar1(E861A/E861A) were rescued by concurrent deletion of the cytosolic sensor of dsRNA, MDA5. A-to-I editing of endogenous dsRNA is the essential function of ADAR1, preventing the activation of the cytosolic dsRNA response by endogenous transcripts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liddicoat, Brian J -- Piskol, Robert -- Chalk, Alistair M -- Ramaswami, Gokul -- Higuchi, Miyoko -- Hartner, Jochen C -- Li, Jin Billy -- Seeburg, Peter H -- Walkley, Carl R -- R01GM102484/GM/NIGMS NIH HHS/ -- T32 HG000044/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2015 Sep 4;349(6252):1115-20. doi: 10.1126/science.aac7049.

    Description: Retroviruses depend on self-assembly of their capsid proteins (core particle) to yield infectious mature virions. Despite the essential role of the retroviral core, its high polymorphism has hindered high-resolution structural analyses. Here, we report the x-ray structure of the native capsid (CA) protein from bovine leukemia virus. CA is organized as hexamers that deviate substantially from sixfold symmetry, yet adjust to make two-dimensional pseudohexagonal arrays that mimic mature retroviral cores. Intra- and interhexameric quasi-equivalent contacts are uncovered, with flexible trimeric lateral contacts among hexamers, yet preserving very similar dimeric interfaces making the lattice. The conformation of each capsid subunit in the hexamer is therefore dictated by long-range interactions, revealing how the hexamers can also assemble into closed core particles, a relevant feature of retrovirus biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Obal, G -- Trajtenberg, F -- Carrion, F -- Tome, L -- Larrieux, N -- Zhang, X -- Pritsch, O -- Buschiazzo, A -- New York, N.Y. -- Science. 2015 Jul 3;349(6243):95-8. doi: 10.1126/science.aaa5182.

    Description: Human inborn errors of immunity mediated by the cytokines interleukin-17A and interleukin-17F (IL-17A/F) underlie mucocutaneous candidiasis, whereas inborn errors of interferon-gamma (IFN-gamma) immunity underlie mycobacterial disease. We report the discovery of bi-allelic RORC loss-of-function mutations in seven individuals from three kindreds of different ethnic origins with both candidiasis and mycobacteriosis. The lack of functional RORgamma and RORgammaT isoforms resulted in the absence of IL-17A/F-producing T cells in these individuals, probably accounting for their chronic candidiasis. Unexpectedly, leukocytes from RORgamma- and RORgammaT-deficient individuals also displayed an impaired IFN-gamma response to Mycobacterium. This principally reflected profoundly defective IFN-gamma production by circulating gammadelta T cells and CD4(+)CCR6(+)CXCR3(+) alphabeta T cells. In humans, both mucocutaneous immunity to Candida and systemic immunity to Mycobacterium require RORgamma, RORgammaT, or both.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4668938/" 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/PMC4668938/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okada, Satoshi -- Markle, Janet G -- Deenick, Elissa K -- Mele, Federico -- Averbuch, Dina -- Lagos, Macarena -- Alzahrani, Mohammed -- Al-Muhsen, Saleh -- Halwani, Rabih -- Ma, Cindy S -- Wong, Natalie -- Soudais, Claire -- Henderson, Lauren A -- Marzouqa, Hiyam -- Shamma, Jamal -- Gonzalez, Marcela -- Martinez-Barricarte, Ruben -- Okada, Chizuru -- Avery, Danielle T -- Latorre, Daniela -- Deswarte, Caroline -- Jabot-Hanin, Fabienne -- Torrado, Egidio -- Fountain, Jeffrey -- Belkadi, Aziz -- Itan, Yuval -- Boisson, Bertrand -- Migaud, Melanie -- Arlehamn, Cecilia S Lindestam -- Sette, Alessandro -- Breton, Sylvain -- McCluskey, James -- Rossjohn, Jamie -- de Villartay, Jean-Pierre -- Moshous, Despina -- Hambleton, Sophie -- Latour, Sylvain -- Arkwright, Peter D -- Picard, Capucine -- Lantz, Olivier -- Engelhard, Dan -- Kobayashi, Masao -- Abel, Laurent -- Cooper, Andrea M -- Notarangelo, Luigi D -- Boisson-Dupuis, Stephanie -- Puel, Anne -- Sallusto, Federica -- Bustamante, Jacinta -- Tangye, Stuart G -- Casanova, Jean-Laurent -- 8UL1TR000043/TR/NCATS NIH HHS/ -- HHSN272200900044C/AI/NIAID NIH HHS/ -- HHSN272200900044C/PHS HHS/ -- R37 AI095983/AI/NIAID NIH HHS/ -- R37AI095983/AI/NIAID NIH HHS/ -- T32 AI007512/AI/NIAID NIH HHS/ -- Canadian Institutes of Health Research/Canada -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Aug 7;349(6248):606-13. doi: 10.1126/science.aaa4282.

    Description: An organism with a single recessive loss-of-function allele will typically have a wild-type phenotype, whereas individuals homozygous for two copies of the allele will display a mutant phenotype. We have developed a method called the mutagenic chain reaction (MCR), which is based on the CRISPR/Cas9 genome-editing system for generating autocatalytic mutations, to produce homozygous loss-of-function mutations. In Drosophila, we found that MCR mutations efficiently spread from their chromosome of origin to the homologous chromosome, thereby converting heterozygous mutations to homozygosity in the vast majority of somatic and germline cells. MCR technology should have broad applications in diverse organisms.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4687737/" 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/PMC4687737/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gantz, Valentino M -- Bier, Ethan -- R01 AI070654/AI/NIAID NIH HHS/ -- R01 AI110713/AI/NIAID NIH HHS/ -- R01 GM067247/GM/NIGMS NIH HHS/ -- R56 NS029870/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2015 Apr 24;348(6233):442-4. doi: 10.1126/science.aaa5945.

    Description: Severe influenza disease strikes otherwise healthy children and remains unexplained. We report compound heterozygous null mutations in IRF7, which encodes the transcription factor interferon regulatory factor 7, in an otherwise healthy child who suffered life-threatening influenza during primary infection. In response to influenza virus, the patient's leukocytes and plasmacytoid dendritic cells produced very little type I and III interferons (IFNs). Moreover, the patient's dermal fibroblasts and induced pluripotent stem cell (iPSC)-derived pulmonary epithelial cells produced reduced amounts of type I IFN and displayed increased influenza virus replication. These findings suggest that IRF7-dependent amplification of type I and III IFNs is required for protection against primary infection by influenza virus in humans. They also show that severe influenza may result from single-gene inborn errors of immunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4431581/" 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/PMC4431581/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ciancanelli, Michael J -- Huang, Sarah X L -- Luthra, Priya -- Garner, Hannah -- Itan, Yuval -- Volpi, Stefano -- Lafaille, Fabien G -- Trouillet, Celine -- Schmolke, Mirco -- Albrecht, Randy A -- Israelsson, Elisabeth -- Lim, Hye Kyung -- Casadio, Melina -- Hermesh, Tamar -- Lorenzo, Lazaro -- Leung, Lawrence W -- Pedergnana, Vincent -- Boisson, Bertrand -- Okada, Satoshi -- Picard, Capucine -- Ringuier, Benedicte -- Troussier, Francoise -- Chaussabel, Damien -- Abel, Laurent -- Pellier, Isabelle -- Notarangelo, Luigi D -- Garcia-Sastre, Adolfo -- Basler, Christopher F -- Geissmann, Frederic -- Zhang, Shen-Ying -- Snoeck, Hans-Willem -- Casanova, Jean-Laurent -- 1U19AI109945/AI/NIAID NIH HHS/ -- 5R01AI100887/AI/NIAID NIH HHS/ -- 5R01NS072381/NS/NINDS NIH HHS/ -- 8UL1TR000043/TR/NCATS NIH HHS/ -- HHSN272201400008C/PHS HHS/ -- R01 AI100887/AI/NIAID NIH HHS/ -- R01 NS072381/NS/NINDS NIH HHS/ -- U19 AI109945/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Apr 24;348(6233):448-53. doi: 10.1126/science.aaa1578.

    Description: Polycomb repressive complex 2 (PRC2) catalyzes histone H3K27 trimethylation (H3K27me3), a hallmark of gene silencing. Here we report the crystal structures of an active PRC2 complex of 170 kilodaltons from the yeast Chaetomium thermophilum in both basal and stimulated states, which contain Ezh2, Eed, and the VEFS domain of Suz12 and are bound to a cancer-associated inhibiting H3K27M peptide and a S-adenosyl-l-homocysteine cofactor. The stimulated complex also contains an additional stimulating H3K27me3 peptide. Eed is engulfed by a belt-like structure of Ezh2, and Suz12(VEFS) contacts both of these two subunits to confer an unusual split active SET domain for catalysis. Comparison of PRC2 in the basal and stimulated states reveals a mobile Ezh2 motif that responds to stimulation to allosterically regulate the active site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiao, Lianying -- Liu, Xin -- GM114576/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Oct 16;350(6258):aac4383. doi: 10.1126/science.aac4383.

    Description: In a short hairpin RNA screen for genes that affect AKT phosphorylation, we identified the RAB35 small guanosine triphosphatase (GTPase)-a protein previously implicated in endomembrane trafficking-as a regulator of the phosphatidylinositol 3'-OH kinase (PI3K) pathway. Depletion of RAB35 suppresses AKT phosphorylation in response to growth factors, whereas expression of a dominant active GTPase-deficient mutant of RAB35 constitutively activates the PI3K/AKT pathway. RAB35 functions downstream of growth factor receptors and upstream of PDK1 and mTORC2 and copurifies with PI3K in immunoprecipitation assays. Two somatic RAB35 mutations found in human tumors generate alleles that constitutively activate PI3K/AKT signaling, suppress apoptosis, and transform cells in a PI3K-dependent manner. Furthermore, oncogenic RAB35 is sufficient to drive platelet-derived growth factor receptor alpha to LAMP2-positive endomembranes in the absence of ligand, suggesting that there may be latent oncogenic potential in dysregulated endomembrane trafficking.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4600465/" 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/PMC4600465/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wheeler, Douglas B -- Zoncu, Roberto -- Root, David E -- Sabatini, David M -- Sawyers, Charles L -- 1DP2CA195761-01/CA/NCI NIH HHS/ -- AI47389/AI/NIAID NIH HHS/ -- CA092629/CA/NCI NIH HHS/ -- CA103866/CA/NCI NIH HHS/ -- CA155169/CA/NCI NIH HHS/ -- GM07739/GM/NIGMS NIH HHS/ -- R01 CA103866/CA/NCI NIH HHS/ -- R01 CA129105/CA/NCI NIH HHS/ -- R01 CA155169/CA/NCI NIH HHS/ -- R01 CA193837/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Oct 9;350(6257):211-7. doi: 10.1126/science.aaa4903.

    Description: The evolution of sexual reproduction is often explained by Red Queen dynamics: Organisms must continually evolve to maintain fitness relative to interacting organisms, such as parasites. Recombination accompanies sexual reproduction and helps diversify an organism's offspring, so that parasites cannot exploit static host genotypes. Here we show that Drosophila melanogaster plastically increases the production of recombinant offspring after infection. The response is consistent across genetic backgrounds, developmental stages, and parasite types but is not induced after sterile wounding. Furthermore, the response appears to be driven by transmission distortion rather than increased recombination. Our study extends the Red Queen model to include the increased production of recombinant offspring and uncovers a remarkable ability of hosts to actively distort their recombination fraction in rapid response to environmental cues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Singh, Nadia D -- Criscoe, Dallas R -- Skolfield, Shelly -- Kohl, Kathryn P -- Keebaugh, Erin S -- Schlenke, Todd A -- New York, N.Y. -- Science. 2015 Aug 14;349(6249):747-50. doi: 10.1126/science.aab1768.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences and Bioinformatics Research Center, North Carolina State University, Raleigh, NC, USA. ndsingh@ncsu.edu schlenkt@reed.edu. ; Translational Biology and Molecular Medicine Program, Baylor College of Medicine, Houston, TX, USA. ; Department of Biology, Reed College, Portland, OR, USA. ; Department of Biology, Winthrop University, Rock Hill, SC, USA. ; Department of Biology, Emory University, Atlanta, GA, USA. ; Department of Biology, Reed College, Portland, OR, USA. ndsingh@ncsu.edu schlenkt@reed.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26273057" target="_blank"〉PubMed〈/a〉

    Description: Macromolecular function is rooted in energy landscapes, where sequence determines not a single structure but an ensemble of conformations. Hence, evolution modifies a protein's function by altering its energy landscape. Here, we recreate the evolutionary pathway between two modern human oncogenes, Src and Abl, by reconstructing their common ancestors. Our evolutionary reconstruction combined with x-ray structures of the common ancestor and pre-steady-state kinetics reveals a detailed atomistic mechanism for selectivity of the successful cancer drug Gleevec. Gleevec affinity is gained during the evolutionary trajectory toward Abl and lost toward Src, primarily by shifting an induced-fit equilibrium that is also disrupted in the clinical T315I resistance mutation. This work reveals the mechanism of Gleevec specificity while offering insights into how energy landscapes evolve.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4405104/" 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/PMC4405104/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, C -- Agafonov, R V -- Hoemberger, M -- Kutter, S -- Zorba, A -- Halpin, J -- Buosi, V -- Otten, R -- Waterman, D -- Theobald, D L -- Kern, D -- GM094468/GM/NIGMS NIH HHS/ -- GM096053/GM/NIGMS NIH HHS/ -- GM100966-01/GM/NIGMS NIH HHS/ -- R01 GM094468/GM/NIGMS NIH HHS/ -- R01 GM096053/GM/NIGMS NIH HHS/ -- R01 GM100966/GM/NIGMS NIH HHS/ -- T32 EB009419/EB/NIBIB NIH HHS/ -- T32 GM007596/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):882-6. doi: 10.1126/science.aaa1823.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Biochemistry, Brandeis University, Waltham, MA 02452, USA. ; Department of Biochemistry, Brandeis University, Waltham, MA 02452, USA. ; Howard Hughes Medical Institute and Department of Biochemistry, Brandeis University, Waltham, MA 02452, USA. dkern@brandeis.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25700521" target="_blank"〉PubMed〈/a〉

    Description: Morphinan alkaloids from the opium poppy are used for pain relief. The direction of metabolites to morphinan biosynthesis requires isomerization of (S)- to (R)-reticuline. Characterization of high-reticuline poppy mutants revealed a genetic locus, designated STORR [(S)- to (R)-reticuline] that encodes both cytochrome P450 and oxidoreductase modules, the latter belonging to the aldo-keto reductase family. Metabolite analysis of mutant alleles and heterologous expression demonstrate that the P450 module is responsible for the conversion of (S)-reticuline to 1,2-dehydroreticuline, whereas the oxidoreductase module converts 1,2-dehydroreticuline to (R)-reticuline rather than functioning as a P450 redox partner. Proteomic analysis confirmed that these two modules are contained on a single polypeptide in vivo. This modular assembly implies a selection pressure favoring substrate channeling. The fusion protein STORR may enable microbial-based morphinan production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winzer, Thilo -- Kern, Marcelo -- King, Andrew J -- Larson, Tony R -- Teodor, Roxana I -- Donninger, Samantha L -- Li, Yi -- Dowle, Adam A -- Cartwright, Jared -- Bates, Rachel -- Ashford, David -- Thomas, Jerry -- Walker, Carol -- Bowser, Tim A -- Graham, Ian A -- BB/K018809/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 Jul 17;349(6245):309-12. doi: 10.1126/science.aab1852.

    Description: Anion exchanger 1 (AE1), also known as band 3 or SLC4A1, plays a key role in the removal of carbon dioxide from tissues by facilitating the exchange of chloride and bicarbonate across the plasma membrane of erythrocytes. An isoform of AE1 is also present in the kidney. Specific mutations in human AE1 cause several types of hereditary hemolytic anemias and/or distal renal tubular acidosis. Here we report the crystal structure of the band 3 anion exchanger domain (AE1(CTD)) at 3.5 angstroms. The structure is locked in an outward-facing open conformation by an inhibitor. Comparing this structure with a substrate-bound structure of the uracil transporter UraA in an inward-facing conformation allowed us to identify the anion-binding position in the AE1(CTD), and to propose a possible transport mechanism that could explain why selected mutations lead to disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arakawa, Takatoshi -- Kobayashi-Yurugi, Takami -- Alguel, Yilmaz -- Iwanari, Hiroko -- Hatae, Hinako -- Iwata, Momi -- Abe, Yoshito -- Hino, Tomoya -- Ikeda-Suno, Chiyo -- Kuma, Hiroyuki -- Kang, Dongchon -- Murata, Takeshi -- Hamakubo, Takao -- Cameron, Alexander D -- Kobayashi, Takuya -- Hamasaki, Naotaka -- Iwata, So -- BB/D019516/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G023425/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- WT089809/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Nov 6;350(6261):680-4. doi: 10.1126/science.aaa4335.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Japan Science and Technology Agency (JST), Exploratory Research for Advanced Technology (ERATO) Human Receptor Crystallography Project, Konoe-cho, Yoshida, Sakyo-ku, Kyoto 606-8501, Japan.

    Description: The pathological assembly of Abeta, tau, and alpha-synuclein is at the heart of Alzheimer's and Parkinson's diseases. Extracellular deposits of Abeta and intraneuronal tau inclusions define Alzheimer's disease, whereas intracellular inclusions of alpha-synuclein make up the Lewy pathology of Parkinson's disease. Most cases of disease are sporadic, but some are inherited in a dominant manner. Mutations frequently occur in the genes encoding Abeta, tau, and alpha-synuclein. Overexpression of these mutant proteins can give rise to disease-associated phenotypes. Protein assembly begins in specific regions of the brain during the process of Alzheimer's and Parkinson's diseases, from where it spreads to other areas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goedert, Michel -- U105184291/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 Aug 7;349(6248):1255555. doi: 10.1126/science.1255555.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Biology, Medical Research Council, Francis Crick Avenue, Cambridge CB2 0QH, UK. mg@mrc-lmb.cam.ac.uk.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26250687" target="_blank"〉PubMed〈/a〉

    Description: The relationship between microRNA (miRNA) regulation and the specification of behavior is only beginning to be explored. We found that mutation of a single miRNA locus (miR-iab4/iab8) in Drosophila larvae affects the animal's capacity to correct its orientation if turned upside down (self-righting). One of the miRNA targets involved in this behavior is the Hox gene Ultrabithorax, whose derepression in two metameric neurons leads to self-righting defects. In vivo neural activity analysis reveals that these neurons, the self-righting node (SRN), have different activity patterns in wild type and miRNA mutants, whereas thermogenetic manipulation of SRN activity results in changes in self-righting behavior. Our work thus reveals a miRNA-encoded behavior and suggests that other miRNAs might also be involved in behavioral control in Drosophila and other species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Picao-Osorio, Joao -- Johnston, Jamie -- Landgraf, Matthias -- Berni, Jimena -- Alonso, Claudio R -- 092986/Z/Wellcome Trust/United Kingdom -- 098410/Z/12/Z/Wellcome Trust/United Kingdom -- 105568/Z/14/Z/Wellcome Trust/United Kingdom -- BB/I022414/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 Nov 13;350(6262):815-20. doi: 10.1126/science.aad0217.

    Description: Posttranslational histone modifications are believed to allow the epigenetic transmission of distinct chromatin states, independently of associated DNA sequences. Histone H3 lysine 9 (H3K9) methylation is essential for heterochromatin formation; however, a demonstration of its epigenetic heritability is lacking. Fission yeast has a single H3K9 methyltransferase, Clr4, that directs all H3K9 methylation and heterochromatin. Using releasable tethered Clr4 reveals that an active process rapidly erases H3K9 methylation from tethering sites in wild-type cells. However, inactivation of the putative histone demethylase Epe1 allows H3K9 methylation and silent chromatin maintenance at the tethering site through many mitotic divisions, and transgenerationally through meiosis, after release of tethered Clr4. Thus, H3K9 methylation is a heritable epigenetic mark whose transmission is usually countered by its active removal, which prevents the unauthorized inheritance of heterochromatin.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4397586/" 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/PMC4397586/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Audergon, Pauline N C B -- Catania, Sandra -- Kagansky, Alexander -- Tong, Pin -- Shukla, Manu -- Pidoux, Alison L -- Allshire, Robin C -- 092076/Wellcome Trust/United Kingdom -- 093852/Wellcome Trust/United Kingdom -- 095021/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Apr 3;348(6230):132-5. doi: 10.1126/science.1260638.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Centre for Cell Biology and Institute of Cell Biology, School of Biological Sciences, The University of Edinburgh, Max Born Crescent, Edinburgh EH9 3BF, Scotland, UK. ; Wellcome Trust Centre for Cell Biology and Institute of Cell Biology, School of Biological Sciences, The University of Edinburgh, Max Born Crescent, Edinburgh EH9 3BF, Scotland, UK. robin.allshire@ed.ac.uk.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25838386" target="_blank"〉PubMed〈/a〉

    Description: Mountain gorillas are an endangered great ape subspecies and a prominent focus for conservation, yet we know little about their genomic diversity and evolutionary past. We sequenced whole genomes from multiple wild individuals and compared the genomes of all four Gorilla subspecies. We found that the two eastern subspecies have experienced a prolonged population decline over the past 100,000 years, resulting in very low genetic diversity and an increased overall burden of deleterious variation. A further recent decline in the mountain gorilla population has led to extensive inbreeding, such that individuals are typically homozygous at 34% of their sequence, leading to the purging of severely deleterious recessive mutations from the population. We discuss the causes of their decline and the consequences for their future survival.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4668944/" 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/PMC4668944/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xue, Yali -- Prado-Martinez, Javier -- Sudmant, Peter H -- Narasimhan, Vagheesh -- Ayub, Qasim -- Szpak, Michal -- Frandsen, Peter -- Chen, Yuan -- Yngvadottir, Bryndis -- Cooper, David N -- de Manuel, Marc -- Hernandez-Rodriguez, Jessica -- Lobon, Irene -- Siegismund, Hans R -- Pagani, Luca -- Quail, Michael A -- Hvilsom, Christina -- Mudakikwa, Antoine -- Eichler, Evan E -- Cranfield, Michael R -- Marques-Bonet, Tomas -- Tyler-Smith, Chris -- Scally, Aylwyn -- 098051/Wellcome Trust/United Kingdom -- 099769/Z/12/Z/Wellcome Trust/United Kingdom -- 260372/European Research Council/International -- HG002385/HG/NHGRI NIH HHS/ -- R01 HG002385/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Apr 10;348(6231):242-5. doi: 10.1126/science.aaa3952.

    Description: Mutations in sunlight-induced melanoma arise from cyclobutane pyrimidine dimers (CPDs), DNA photoproducts that are typically created picoseconds after an ultraviolet (UV) photon is absorbed at thymine or cytosine. We found that in melanocytes, CPDs are generated for 〉3 hours after exposure to UVA, a major component of the radiation in sunlight and in tanning beds. These "dark CPDs" constitute the majority of CPDs and include the cytosine-containing CPDs that initiate UV-signature C--〉T mutations. Dark CPDs arise when UV-induced reactive oxygen and nitrogen species combine to excite an electron in fragments of the pigment melanin. This creates a quantum triplet state that has the energy of a UV photon but induces CPDs by energy transfer to DNA in a radiation-independent manner. Melanin may thus be carcinogenic as well as protective against cancer. These findings also validate the long-standing suggestion that chemically generated excited electronic states are relevant to mammalian biology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4432913/" 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/PMC4432913/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Premi, Sanjay -- Wallisch, Silvia -- Mano, Camila M -- Weiner, Adam B -- Bacchiocchi, Antonella -- Wakamatsu, Kazumasa -- Bechara, Etelvino J H -- Halaban, Ruth -- Douki, Thierry -- Brash, Douglas E -- 2 P50 CA121974/CA/NCI NIH HHS/ -- P30 DK034989/DK/NIDDK NIH HHS/ -- P30 DK34989/DK/NIDDK NIH HHS/ -- P50 CA121974/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):842-7. doi: 10.1126/science.1256022.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Therapeutic Radiology, Yale University School of Medicine, New Haven, CT 06520, USA. ; Department of Therapeutic Radiology, Yale University School of Medicine, New Haven, CT 06520, USA.

    Description: Mammalian mitochondrial ribosomes (mitoribosomes) synthesize mitochondrially encoded membrane proteins that are critical for mitochondrial function. Here we present the complete atomic structure of the porcine 55S mitoribosome at 3.8 angstrom resolution by cryo-electron microscopy and chemical cross-linking/mass spectrometry. The structure of the 28S subunit in the complex was resolved at 3.6 angstrom resolution by focused alignment, which allowed building of a detailed atomic structure including all of its 15 mitoribosomal-specific proteins. The structure reveals the intersubunit contacts in the 55S mitoribosome, the molecular architecture of the mitoribosomal messenger RNA (mRNA) binding channel and its interaction with transfer RNAs, and provides insight into the highly specialized mechanism of mRNA recruitment to the 28S subunit. Furthermore, the structure contributes to a mechanistic understanding of aminoglycoside ototoxicity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greber, Basil J -- Bieri, Philipp -- Leibundgut, Marc -- Leitner, Alexander -- Aebersold, Ruedi -- Boehringer, Daniel -- Ban, Nenad -- New York, N.Y. -- Science. 2015 Apr 17;348(6232):303-8. doi: 10.1126/science.aaa3872.

    Description: Development of the cerebral cortex is influenced by sensory experience during distinct phases of postnatal development known as critical periods. Disruption of experience during a critical period produces neurons that lack specificity for particular stimulus features, such as location in the somatosensory system. Synaptic plasticity is the agent by which sensory experience affects cortical development. Here, we describe, in mice, a developmental critical period that affects plasticity itself. Transient neonatal disruption of signaling via the C-terminal domain of "disrupted in schizophrenia 1" (DISC1)-a molecule implicated in psychiatric disorders-resulted in a lack of long-term potentiation (LTP) (persistent strengthening of synapses) and experience-dependent potentiation in adulthood. Long-term depression (LTD) (selective weakening of specific sets of synapses) and reversal of LTD were present, although impaired, in adolescence and absent in adulthood. These changes may form the basis for the cognitive deficits associated with mutations in DISC1 and the delayed onset of a range of psychiatric symptoms in late adolescence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greenhill, Stuart D -- Juczewski, Konrad -- de Haan, Annelies M -- Seaton, Gillian -- Fox, Kevin -- Hardingham, Neil R -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 Jul 24;349(6246):424-7. doi: 10.1126/science.aaa8481.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biosciences, Cardiff University, Cardiff, CF23 3AX, UK. ; National Institute on Alcohol Abuse and Alcoholism, NIH, Rockville, MD 20852, USA. ; School of Biosciences, Cardiff University, Cardiff, CF23 3AX, UK. sbinrh@cardiff.ac.uk.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26206934" target="_blank"〉PubMed〈/a〉

    Description: The root meristem consists of populations of distal and proximal stem cells and an organizing center known as the quiescent center. During embryogenesis, initiation of the root meristem occurs when an asymmetric cell division of the hypophysis forms the distal stem cells and quiescent center. We have identified NO TRANSMITTING TRACT (NTT) and two closely related paralogs as being required for the initiation of the root meristem. All three genes are expressed in the hypophysis, and their expression is dependent on the auxin-signaling pathway. Expression of these genes is necessary for distal stem cell fate within the root meristem, whereas misexpression is sufficient to transform other stem cell populations to a distal stem cell fate in both the embryo and mature roots.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crawford, Brian C W -- Sewell, Jared -- Golembeski, Greg -- Roshan, Carmel -- Long, Jeff A -- Yanofsky, Martin F -- 5 R01 GM072764/GM/NIGMS NIH HHS/ -- R01 GM072764/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Feb 6;347(6222):655-9. doi: 10.1126/science.aaa0196.

    Description: Eukaryotic cells coordinate growth with the availability of nutrients through the mechanistic target of rapamycin complex 1 (mTORC1), a master growth regulator. Leucine is of particular importance and activates mTORC1 via the Rag guanosine triphosphatases and their regulators GATOR1 and GATOR2. Sestrin2 interacts with GATOR2 and is a leucine sensor. Here we present the 2.7 angstrom crystal structure of Sestrin2 in complex with leucine. Leucine binds through a single pocket that coordinates its charged functional groups and confers specificity for the hydrophobic side chain. A loop encloses leucine and forms a lid-latch mechanism required for binding. A structure-guided mutation in Sestrin2 that decreases its affinity for leucine leads to a concomitant increase in the leucine concentration required for mTORC1 activation in cells. These results provide a structural mechanism of amino acid sensing by the mTORC1 pathway.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4698039/" 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/PMC4698039/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saxton, Robert A -- Knockenhauer, Kevin E -- Wolfson, Rachel L -- Chantranupong, Lynne -- Pacold, Michael E -- Wang, Tim -- Schwartz, Thomas U -- Sabatini, David M -- AI47389/AI/NIAID NIH HHS/ -- F30 CA189333/CA/NCI NIH HHS/ -- F31 CA180271/CA/NCI NIH HHS/ -- F31 CA189437/CA/NCI NIH HHS/ -- P41 GM103403/GM/NIGMS NIH HHS/ -- R01 AI047389/AI/NIAID NIH HHS/ -- R01 CA103866/CA/NCI NIH HHS/ -- R01CA103866/CA/NCI NIH HHS/ -- S10 RR029205/RR/NCRR NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- T32GM007287/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Jan 1;351(6268):53-8. doi: 10.1126/science.aad2087.

    Description: Transcriptional activation of the human interleukin-2 (IL-2) gene, like induction of the IL-2 receptor alpha (IL-2R alpha) gene and the type 1 human immunodeficiency virus (HIV-1), is shown to be modulated by a kappa B-like enhancer element. Mutation of a kappa B core sequence identified in the IL-2 promoter (-206 to -195) partially inhibits both mitogen- and HTLV-I Tax-mediated activation of this transcription unit and blocks the specific binding of two inducible cellular factors. These kappa B-specific proteins (80 to 90 and 50 to 55 kilodaltons) similarly interact with the functional kappa B enhancer present in the IL-2R alpha promoter. These data suggest that these kappa B-specific proteins have a role in the coordinate regulation of this growth factor-growth factor receptor gene system that controls T cell proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoyos, B -- Ballard, D W -- Bohnlein, E -- Siekevitz, M -- Greene, W C -- A127053-01/PHS HHS/ -- New York, N.Y. -- Science. 1989 Apr 28;244(4903):457-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mount Sinai Medical Center, Department of Microbiology, New York, NY 10029.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2497518" target="_blank"〉PubMed〈/a〉

    Description: Protein engineering and x-ray crystallography have been used to study the role of a surface loop that is present in pancreatic phospholipases but is absent in snake venom phospholipases. Removal of residues 62 to 66 from porcine pancreatic phospholipase A2 does not change the binding constant for micelles significantly, but it improves catalytic activity up to 16 times on micellar (zwitterionic) lecithin substrates. In contrast, the decrease in activity on negatively charged substrates is greater than fourfold. A crystallographic study of the mutant enzyme shows that the region of the deletion has a well-defined structure that differs from the structure of the wild-type enzyme. No structural changes in the active site of the enzyme were detected.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuipers, O P -- Thunnissen, M M -- de Geus, P -- Dijkstra, B W -- Drenth, J -- Verheij, H M -- de Haas, G H -- New York, N.Y. -- Science. 1989 Apr 7;244(4900):82-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Utrecht, The Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2704992" target="_blank"〉PubMed〈/a〉

    Description: DNA mismatch correction is a strand-specific process involving recognition of noncomplementary Watson-Crick nucleotide pairs and participation of widely separated DNA sites. The Escherichia coli methyl-directed reaction has been reconstituted in a purified system consisting of MutH, MutL, and MutS proteins, DNA helicase II, single-strand DNA binding protein, DNA polymerase III holoenzyme, exonuclease I, DNA ligase, along with ATP (adenosine triphosphate), and the four deoxynucleoside triphosphates. This set of proteins can process seven of the eight base-base mismatches in a strand-specific reaction that is directed by the state of methylation of a single d(GATC) sequence located 1 kilobase from the mispair.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lahue, R S -- Au, K G -- Modrich, P -- F32 GM12684/GM/NIGMS NIH HHS/ -- GM23719/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jul 14;245(4914):160-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Duke University Medical Center, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2665076" target="_blank"〉PubMed〈/a〉

    Description: CD4 is a cell surface glycoprotein that is thought to interact with nonpolymorphic determinants of class II major histocompatibility (MHC) molecules. CD4 is also the receptor for the human immunodeficiency virus (HIV), binding with high affinity to the HIV-1 envelope glycoprotein, gp120. Homolog-scanning mutagenesis was used to identify CD4 regions that are important in class II MHC binding and to determine whether the gp120 and class II MHC binding sites of CD4 are related. Class II MHC binding was abolished by mutations in each of the first three immunoglobulin-like domains of CD4. The gp120 binding could be abolished without affecting class II MHC binding and vice versa, although at least one mutation examined reduced both functions significantly. These findings indicate that, while there may be overlap between the gp120 and class II MHC binding sites of CD4, these sites are distinct and can be separated. Thus it should be possible to design CD4 analogs that can block HIV infectivity but intrinsically lack the ability to affect the normal immune response by binding to class II MHC molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamarre, D -- Ashkenazi, A -- Fleury, S -- Smith, D H -- Sekaly, R P -- Capon, D J -- New York, N.Y. -- Science. 1989 Aug 18;245(4919):743-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire d'Immunologie, Institut de Recherches Cliniques de Montreal, Quebec, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2549633" target="_blank"〉PubMed〈/a〉

    Description: C/EBP is a rat liver nuclear protein capable of sequence-specific interaction with DNA. The DNA sequences to which C/EBP binds in vitro have been implicated in the control of messenger RNA synthesis. It has therefore been predicted that C/EBP will play a role in regulating gene expression in mammalian cells. The region of the C/EBP polypeptide required for direct interaction with DNA has been identified and shown to bear amino acid sequence relatedness with the product of the myc, fos, and jun proto-oncogenes. The arrangement of these related amino acid sequences led to the prediction of a new structural motif, termed the "leucine zipper," that plays a role in facilitating sequence-specific interaction between protein and DNA. Experimental tests now provide support for the leucine zipper hypothesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Landschulz, W H -- Johnson, P F -- McKnight, S L -- New York, N.Y. -- Science. 1989 Mar 31;243(4899):1681-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Carnegie Institution of Washington, Department of Embryology, Baltimore, MD 21210.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2494700" target="_blank"〉PubMed〈/a〉

    Description: Spondyloepiphyseal dysplasias (SED) are a heterogeneous group of inherited disorders characterized by disproportionate short stature and pleiotropic involvement of the skeletal and ocular systems. Evidence has suggested that SED may result from structural defects in type II collagen. To confirm the validity of this hypothesis, the structure of the "candidate" type II collagen gene (COL2A1) has been directly examined in a relatively large SED family. Coarse scanning of the gene by Southern blot hybridization identified an abnormal restriction pattern in one of the affected members of the kindred. Analysis of selected genomic fragments, amplified by the polymerase chain reaction, precisely localized the molecular defect and demonstrated that all affected family members carried the same heterozygous single-exon deletion. As a consequence of the mutation, nearly 90 percent of the assembled type II collagen homotrimers are expected to contain one or more procollagen subunits harboring an interstitial deletion of 36 amino acids in the triple helical domain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, B -- Vissing, H -- Ramirez, F -- Rogers, D -- Rimoin, D -- AR-38648/AR/NIAMS NIH HHS/ -- HD-22657/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1989 May 26;244(4907):978-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, State University of New York Health Science Center, Brooklyn 11203.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2543071" target="_blank"〉PubMed〈/a〉

    Description: Embryonal carcinoma (EC) cell lines are models for early cells in mouse embryogenesis. A 300-base pair fragment of the heavy chain enhancer was inactive in F9 EC cells, unlike in other nonlymphoid cells where it has significant activity. Alterations of the octamer motif increased enhancer activity. Nuclear extracts from F9 cells contained an octamer binding protein (NF-A3) that was unique to EC cells; the amount of NF-A3 decreased upon differentiation. It is proposed that NF-A3 represses specific regulatory sequences that contain the octamer motif. Thus, the same DNA sequence mediates either negative or positive transcriptional effects, depending on the cell type.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lenardo, M J -- Staudt, L -- Robbins, P -- Kuang, A -- Mulligan, R C -- Baltimore, D -- CA 01074/CA/NCI NIH HHS/ -- HD0063/HD/NICHD NIH HHS/ -- HL37569/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Jan 27;243(4890):544-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2536195" target="_blank"〉PubMed〈/a〉

    Description: Complementary DNA clones, encoding the LH-hCG (luteinizing hormone-human choriogonadotropic hormone) receptor were isolated by screening a lambda gt11 library with monoclonal antibodies. The primary structure of the protein was deduced from the DNA sequence analysis; the protein contains 696 amino acids with a putative signal peptide of 27 amino acids. Hydropathy analysis suggests the existence of seven transmembrane domains that show homology with the corresponding regions of other G protein-coupled receptors. Three other types of clones corresponding to shorter proteins were observed, in which the putative transmembrane domain was absent. These probably arose through alternative splicing. RNA blot analysis showed similar patterns in testis and ovary with a major RNA of 4700 nucleotides and several minor species. The messenger RNA was expressed in COS-7 cells, yielding a protein that bound hCG with the same affinity as the testicular receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loosfelt, H -- Misrahi, M -- Atger, M -- Salesse, R -- Vu Hai-Luu Thi, M T -- Jolivet, A -- Guiochon-Mantel, A -- Sar, S -- Jallal, B -- Garnier, J -- New York, N.Y. -- Science. 1989 Aug 4;245(4917):525-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Sante et de la Recherche Medicale Unite 135, Hopital de Bicetre, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2502844" target="_blank"〉PubMed〈/a〉

    Description: The fragile X syndrome is the most common cause of familial mental retardation. Genetic counseling and gene isolation are hampered by a lack of DNA markers close to the disease locus. Two somatic cell hybrids that each contain a human X chromosome with a breakpoint close to the fragile X locus have been characterized. A new DNA marker (DXS296) lies between the chromosome breakpoints and is the closest marker to the fragile X locus yet reported. The Hunter syndrome gene, which causes iduronate sulfatase deficiency, is located at the X chromosome breakpoint that is distal to this new marker, thus localizing the Hunter gene distal to the fragile X locus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suthers, G K -- Callen, D F -- Hyland, V J -- Kozman, H M -- Baker, E -- Eyre, H -- Harper, P S -- Roberts, S H -- Hors-Cayla, M C -- Davies, K E -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1298-300.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Histopathology, Adelaide Children's Hospital, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2573953" target="_blank"〉PubMed〈/a〉

    Description: Allele loss is a hallmark of chromosome regions harboring recessive oncogenes. Lung cancer frequently demonstrates loss of heterozygosity on 17p. Recent evidence suggests that the p53 gene located on 17p13 has many features of such an antioncogene. The p53 gene was frequently mutated or inactivated in all types of human lung cancer. The genetic abnormalities of p53 include gross changes such as homozygous deletions and abnormally sized messenger RNAs along with a variety of point or small mutations, which map to the p53 open reading frame and change amino acid sequence in a region highly conserved between mouse and man. In addition, very low or absent expression of p53 messenger RNA in lung cancer cell lines compared to normal lung was seen. These findings, coupled with the previous demonstration of 17p allele loss in lung cancer, strongly implicate p53 as an anti-oncogene whose disruption is involved in the pathogenesis of human lung cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takahashi, T -- Nau, M M -- Chiba, I -- Birrer, M J -- Rosenberg, R K -- Vinocour, M -- Levitt, M -- Pass, H -- Gazdar, A F -- Minna, J D -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):491-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Cancer Institute-Navy Medical Oncology Branch, Bethesda, MD 20814.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2554494" target="_blank"〉PubMed〈/a〉

    Description: The temperature dependences of the reduction potentials (E degrees') of wild-type human myoglobin (Mb) and three site-directed mutants have been measured by the use of thin-layer spectroelectrochemistry. Residue Val68, which is in van der Waals contact with the heme in Mb, has been replaced by Glu, Asp, and Asn. The changes in E degrees' and the standard entropy (delta S degrees') and enthalpy (delta H degrees') of reduction in the mutant proteins were determined relative to values for wild type; the change in E degrees' at 25 degrees C was about -200 millivolts for the Glu and Asp mutants, and about -80 millivolts for the Asn mutant. At pH 7.0, reduction of Fe(III) to Fe(II) in the Glu and Asp mutants is accompanied by uptake of a proton by the protein. These studies demonstrate that Mb can tolerate substitution of a buried hydrophobic group by potentially charged and polar residues and that such amino acid replacements can lead to substantial changes in the redox thermodynamics of the protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Varadarajan, R -- Zewert, T E -- Gray, H B -- Boxer, S G -- DK 19038/DK/NIDDK NIH HHS/ -- GM 27738/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 6;243(4887):69-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2563171" target="_blank"〉PubMed〈/a〉

This enhancer functions in human hepatoma cells, where it is much more active than the previously described HBV enhancer in stimulating expression of the linked bacterial chloramphenicol acetyltransferase gene expressed from heterologous promoters. Studies of the role of this enhancer-promoter in HBV may help to clarify mechanisms of gene expression in cells infected with HBV and the role of the virus in the pathogenesis of hepatitis and hepatocellular carcinoma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yee, J K -- New York, N.Y. -- Science. 1989 Nov 3;246(4930):658-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, School of Medicine, University of California, San Diego, La Jolla 92093.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2554495" target="_blank"〉PubMed〈/a〉

    Description: Mammalian glucocorticoid receptors enhance transcription from linked promoters by binding to glucocorticoid response element (GRE) DNA sequences. Understanding the mechanism of receptor action will require biochemical studies with purified components. Enhancement was observed in vitro with derivatives of the receptor that were expressed in Escherichia coli, purified, and added to a cell-free extract from Drosophila embryo nuclei. Transcription from promoters linked to one or multiple GREs was selectively enhanced by as much as six times.

    Description: Immunization with chemically detoxified pertussis toxin can prevent severe whooping cough with an efficacy similar to that of the cellular pertussis vaccine, which normally gives unwanted side effects. To avoid the reversion to toxicity and the loss of immunogenicity that may follow chemical treatment of pertussis toxin, inactive toxins were constructed by genetic manipulation. A number of genetically engineered alleles of the pertussis toxin genes, constructed by replacing either one or two key amino acids within the enzymatically active S1 subunit, were introduced into the chromosome of strains of Bordetella pertussis, B. parapertussis, and B. bronchiseptica. These strains produce mutant pertussis toxin molecules that are nontoxic and immunogenic and that protect mice from the intracerebral challenge with virulent Bordetella pertussis. Such molecules are ideal for the development of new and safer vaccines against whooping cough.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pizza, M -- Covacci, A -- Bartoloni, A -- Perugini, M -- Nencioni, L -- De Magistris, M T -- Villa, L -- Nucci, D -- Manetti, R -- Bugnoli, M -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):497-500.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sclavo Research Center, Siena, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2683073" target="_blank"〉PubMed〈/a〉

    Description: The nitrogen regulatory (NtrC) protein of enteric bacteria, which binds to sites that have the properties of transcriptional enhancers, is known to activate transcription by a form of RNA polymerase that contains the NtrA protein (sigma 54) as sigma factor (referred to as sigma 54-holoenzyme). In the presence of adenosine triphosphate, the NtrC protein catalyzes isomerization of closed recognition complexes between sigma 54-holoenzyme and the glnA promoter to open complexes in which DNA in the region of the transcription start site is locally denatured. NtrC is not required subsequently for maintenance of open complexes or initiation of transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Popham, D L -- Szeto, D -- Keener, J -- Kustu, S -- GM38361/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 3;243(4891):629-35.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of California, Berkley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2563595" target="_blank"〉PubMed〈/a〉

    Description: Expression of the c-myc oncogene is deregulated in a variety of malignancies. Rearrangement and mutation of the c-myc locus is a characteristic feature of human Burkitt's lymphoma. Whether deregulation is solely a result of mutation of c-myc or whether it is influenced by the transformed B cell context has not been determined. A translocated and mutated allele of c-myc was stably transfected into fibroblasts. The rearranged allele was expressed indistinguishably from a normal c-myc gene: it had serum-regulated expression, was transcribed with normal promoter preference, and was strongly attenuated. Thus mutations by themselves are insufficient to deregulate c-myc transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richman, A -- Hayday, A -- 40364/PHS HHS/ -- GM 07499/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):494-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biology Department, Yale University, New Haven, CT 06511.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2683072" target="_blank"〉PubMed〈/a〉

    Description: Tumor suppressor genes are wild-type alleles of genes that play regulatory roles in cell proliferation, differentiation, and other cellular and systemic processes. It is their loss or inactivation that is oncogenic. The first evidence of tumor suppressor genes appeared in the early 1970s, but only within the past few years has a wealth of new information illuminated the central importance of these genes. Two or more different suppressor genes may be inactivated in the same tumors, and the same suppressors may be inactive in different tumor types (for example, lung, breast, and colon). The suppressor genes already identified are involved in cell cycle control, signal transduction, angiogenesis, and development, indicating that they contribute to a broad array of normal and tumor-related functions. It is proposed that tumor suppressor genes provide a vast untapped resource for anticancer therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sager, R -- New York, N.Y. -- Science. 1989 Dec 15;246(4936):1406-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cancer Genetics, Dana-Farber Cancer Institute, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2574499" target="_blank"〉PubMed〈/a〉

    Description: In Drosophila, five "terminal" polarity genes must be active in females in order for them to produce embryos with normal anterior and posterior ends. Hypoactivity mutations in one such gene, torso, result in the loss of the most posterior domain of fushi tarazu expression and the terminal cuticular structures. In contrast, a torso hyperactivity mutation causes the loss of central fushi tarazu expression and central cuticular structures. Cytoplasmic leakage, transplantation, and temperature-shift experiments suggest that the latter effect is caused by abnormal persistence of the torso product in the central region of the embryo during early development. Thus, the amount and timing of torso activity is key to distinguishing the central and terminal regions of the embryo. Mutations in the tailless terminal gene act as dominant maternal suppressors of the hyperactive torso allele, indicating that the torso product acts through, or in concert with, the tailless product.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Strecker, T R -- Halsell, S R -- Fisher, W W -- Lipshitz, H D -- GM07616/GM/NIGMS NIH HHS/ -- HD23099/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 24;243(4894 Pt 1):1062-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2922596" target="_blank"〉PubMed〈/a〉

    Description: The proposal that the absorption maximum of the visual pigments is governed by interaction of the 11-cis-retinal chromophore with charged carboxylic acid side chains in the membrane-embedded regions of the proteins has been tested by mutating five Asp and Glu residues thought to be buried in rhodopsin. Changing Glu113 to Gln causes a dramatic shift in the absorption maximum from 500 nanometers to 380 nanometers, a decrease in the pKa (acidity constant) of the protonated Schiff base of the chromophore to about 6, and a greatly increased reactivity with hydroxylamine. Thus Glu113 appears to be the counterion to the protonated Schiff base. Wavelength modulation in visual pigments apparently is not governed by electrostatic interaction with carboxylate residues, other than the counterion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhukovsky, E A -- Oprian, D D -- 5T32 GM07596-11/GM/NIGMS NIH HHS/ -- EY07965/EY/NEI NIH HHS/ -- R01 EY007965/EY/NEI NIH HHS/ -- S07 RR07044/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1989 Nov 17;246(4932):928-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Brandeis University, Waltham, MA 02254.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2573154" target="_blank"〉PubMed〈/a〉

    Description: Activation of protein kinase C is thought to require association of the kinase with the cell membrane. It has been assumed that cellular substrates for the kinase must likewise be associated with membranes, and previous studies with membrane-associated myristoylated proteins have supported this view. It is now shown that a mutation that prevents the normal amino-terminal myristoylation of a prominent cellular substrate of protein kinase C, and appears to prevent its membrane association, does not prevent the normal phosphorylation of this protein in intact cells in response to phorbol esters. Thus, membrane association may not be required in order for protein kinase C substrates to undergo phosphorylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graff, J M -- Gordon, J I -- Blackshear, P J -- 2T32-GM 07171/GM/NIGMS NIH HHS/ -- AI27179/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):503-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute Laboratories, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2814478" target="_blank"〉PubMed〈/a〉

    Description: The multiprotein-DNA complexes that participate in bacteriophage lambda site-specific recombination were used to study the combined effect of protein-induced bending and protein-mediated looping of DNA. The protein integrase (Int) is a monomer with two autonomous DNA binding domains of different sequence specificity. Stimulation of Int binding and cleavage at the low affinity core-type DNA sites required interactions with the high affinity arm-type sites and depended on simultaneous binding of the sequence-specific DNA bending protein IHF (integration host factor). The bivalent DNA binding protein is positioned at high affinity sites and directed, by a DNA bending protein, to interactions with distant lower affinity sites. Assembly of this complex is independent of protein-protein interactions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1892171/" 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/PMC1892171/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moitoso de Vargas, L -- Kim, S -- Landy, A -- AI-13544/AI/NIAID NIH HHS/ -- GM-33928/GM/NIGMS NIH HHS/ -- R01 GM033928/GM/NIGMS NIH HHS/ -- R01 GM062723/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 23;244(4911):1457-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology and Medicine, Brown University, Providence, RI 02912.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2544029" target="_blank"〉PubMed〈/a〉

    Description: Blue cone monochromacy is a rare X-linked disorder of color vision characterized by the absence of both red and green cone sensitivities. In 12 of 12 families carrying this trait, alterations are observed in the red and green visual pigment gene cluster. The alterations fall into two classes. One class arose from the wild type by a two-step pathway consisting of unequal homologous recombination and point mutation. The second class arose by nonhomologous deletion of genomic DNA adjacent to the red and green pigment gene cluster. These deletions define a 579-base pair region that is located 4 kilobases upstream of the red pigment gene and 43 kilobases upstream of the nearest green pigment gene; this 579-base pair region is essential for the activity of both pigment genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nathans, J -- Davenport, C M -- Maumenee, I H -- Lewis, R A -- Hejtmancik, J F -- Litt, M -- Lovrien, E -- Weleber, R -- Bachynski, B -- Zwas, F -- New York, N.Y. -- Science. 1989 Aug 25;245(4920):831-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Genetics, Wilmer Ophthalmologic Institute, Johns Hopkins University School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2788922" target="_blank"〉PubMed〈/a〉

    Description: A new method has been developed that makes it possible to site-specifically incorporate unnatural amino acids into proteins. Synthetic amino acids were incorporated into the enzyme beta-lactamase by the use of a chemically acylated suppressor transfer RNA that inserted the amino acid in response to a stop codon substituted for the codon encoding residue of interest. Peptide mapping localized the inserted amino acid to a single peptide, and enough enzyme could be generated for purification to homogeneity. The catalytic properties of several mutants at the conserved Phe66 were characterized. The ability to selectively replace amino acids in a protein with a wide variety of structural and electronic variants should provide a more detailed understanding of protein structure and function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noren, C J -- Anthony-Cahill, S J -- Griffith, M C -- Schultz, P G -- New York, N.Y. -- Science. 1989 Apr 14;244(4901):182-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2649980" target="_blank"〉PubMed〈/a〉

    Description: Granulocyte and natural killer (NK) cell Fc receptors for immunoglobulin G (CD16) differ in only a few amino acids, yet have phosphatidylinositol glycan (PIG) or polypeptide membrane anchors, respectively. Mutagenesis shows that anchoring is regulated by a serine residue near the PIG anchor attachment site in the extracellular domain. The NK cell isoform was not expressed on the surface of COS cells unless cotransfected with a subunit that was expressed in NK cells and that was identical to the gamma subunit of the high affinity IgE Fc receptor (Fc epsilon RI). However, the CD16 sequence and not expression of the gamma subunit is dominant in regulating PIG reanchoring.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hibbs, M L -- Selvaraj, P -- Carpen, O -- Springer, T A -- Kuster, H -- Jouvin, M H -- Kinet, J P -- New York, N.Y. -- Science. 1989 Dec 22;246(4937):1608-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2531918" target="_blank"〉PubMed〈/a〉

    Description: Differential gene expression in the mother cell chamber of sporulating cells of Bacillus subtilis is determined in part by an RNA polymerase sigma factor called sigma K (or sigma 27). The sigma K factor was assigned as the product of the sporulation gene spoIVCB on the basis of the partial aminoterminal amino acid sequence of the purified protein. The spoIVCB gene is now shown to be a truncated gene capable of specifying only the amino terminal half of sigma K. The carboxyl terminal half is specified by another sporulation gene, spoIIIC, to which spoIVCB becomes joined inframe at an intermediate stage of sporulation by site-specific recombination within a 5-base pair repeated sequence. Juxtaposition of spoIVCB and spoIIIC need not be reversible in that the mother cell and its chromosome are discarded at the end of the developmental cycle. The rearrangement of chromosomal DNA could account for the presence of sigma K selectively in the mother cell and may be a precedent for the generation of cell type-specific regulatory proteins in other developmental systems where cells undergo terminal differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stragier, P -- Kunkel, B -- Kroos, L -- Losick, R -- New York, N.Y. -- Science. 1989 Jan 27;243(4890):507-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Developmental Biology, Harvard University, Cambridge, MA 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2536191" target="_blank"〉PubMed〈/a〉

    Description: Protein interiors contain many tightly packed apolar atoms in a nearly crystalline state. Both shielding of apolar atoms from solvent and efficient interior packing arrangements affect protein stability, but their relative importance is unclear. To separate these effects, the stabilities of wild-type and mutant gene V proteins from bacteriophage fl were studied by measuring resistance to denaturation. The effects of subtle interior packing changes, both separate from and combined with changes in buried side chain hydrophobicity, were measured. For the interior apolar-to-apolar substitutions studied, the two effects were of the same magnitude and alteration of packing without accompanying hydrophobicity changes substantially destabilized the protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sandberg, W S -- Terwilliger, T C -- 5732 GM07281/GM/NIGMS NIH HHS/ -- GM38714/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jul 7;245(4913):54-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2787053" target="_blank"〉PubMed〈/a〉

    Description: The insulin receptor has an intrinsic tyrosine kinase activity that is essential for signal transduction. A mutant insulin receptor gene lacking almost the entire kinase domain has been identified in an individual with type A insulin resistance and acanthosis nigricans. Insulin binding to the erythrocytes or cultured fibroblasts from this individual was normal. However receptor autophosphorylation and tyrosine kinase activity toward an exogenous substrate were reduced in partially purified insulin receptors from the proband's lymphocytes that had been transformed by Epstein-Barr virus. The insulin resistance associated with this mutated gene was inherited by the proband from her mother as an apparently autosomal dominant trait. Thus a deletion in one allele of the insulin receptor gene may be at least partly responsible for some instances of insulin-resistant diabetes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taira, M -- Hashimoto, N -- Shimada, F -- Suzuki, Y -- Kanatsuka, A -- Nakamura, F -- Ebina, Y -- Tatibana, M -- Makino, H -- New York, N.Y. -- Science. 1989 Jul 7;245(4913):63-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Second Department of Internal Medicine, Chiba University School of Medicine, Inohana, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2544997" target="_blank"〉PubMed〈/a〉

    Description: During frog embryogenesis, mesoderm is specified in the equatorial region of the early embryo by a signal from the vegetal hemisphere. Prospective ectodermal cells dissected from the animal hemisphere can be respecified to form mesodermal tissues by recombination with vegetal tissue or by treatment with any of several polypeptide growth factors or growth factor-like molecules. Together with the discovery that several developmental mutations in Drosophila are in genes with significant homology to mammalian mitogens and oncogenes, these observations suggest that early developmental signals may use similar transduction pathways to mitogenic signals characterized in cultured mammalian cells. Whether mesoderm can be induced by activation of intracellular signal transduction pathways implicated in mitogenesis and oncogenesis has been investigated with the viral oncogene polyoma middle T. Microinjection of middle T messenger RNA into early embryos results in the respecification of isolated prospective ectodermal tissue to form characteristic mesodermal structures. Middle T in frog blastomeres appears to associate with cellular activities similar to those observed in polyoma-transformed mouse cells, and transformation-defective middle T mutants fail to induce mesoderm. These results suggest that early inductive signals and mitogenic and oncogenic stimuli may share common signal transduction pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitman, M -- Melton, D A -- New York, N.Y. -- Science. 1989 May 19;244(4906):803-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Harvard University, Cambridge, MA 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2658054" target="_blank"〉PubMed〈/a〉

    Description: The chemical identity of the amino acid free-radical site that represents one of the two oxidizing equivalents stored in the H2O2-oxidized intermediate (compound ES) of the mitochondrial heme enzyme, cytochrome c peroxidase (CcP) has been sought for almost a quarter of a century. Site-directed mutagenesis alone cannot yield this answer. Low-temperature 35-gigahertz (Q-band) electron nuclear double resonance (ENDOR) spectroscopy was used to examine compound ES prepared from proteins containing specifically deuterated methionine or tryptophan, as well as the amino acid replacement Trp51----Phe. The results definitely identify the site of the radical in compound ES as tryptophan, most likely Trp191.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sivaraja, M -- Goodin, D B -- Smith, M -- Hoffman, B M -- GM-33804/GM/NIGMS NIH HHS/ -- GM-41049/GM/NIGMS NIH HHS/ -- HL-13531/HL/NHLBI NIH HHS/ -- R01 GM041049/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Aug 18;245(4919):738-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Northwestern University, Evanston, IL 60208.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2549632" target="_blank"〉PubMed〈/a〉

    Description: The discovery that the AP-1 family of enhancer binding factors includes a complex of the cellular Fos (cFos) and cellular Jun (cJun) proteins established a direct and important link between oncogenesis and transcriptional regulation. Homodimeric cJun protein synthesized in vitro is capable of binding selectively to AP-1 recognition sites, whereas the cFos polypeptide is not. When cotranslated, the cFos and cJun proteins can form a stable, heterodimeric complex with the DNA binding properties of AP-1/cJun. The related proteins Jun B and vJun are also able to form DNA binding complexes with cFos. Directed mutagenesis of the cFos protein reveals that a leucine repeat structure is required for binding to cJun, in a manner consistent with the proposed function of the "leucine zipper." A novel domain adjacent to, but distinct from, the leucine repeat of cFos is required for DNA binding by cFos-cJun heterodimers. Thus experimental evidence is presented that leucine repeats can mediate complex formation between heterologous proteins and that promotes further understanding of the molecular mechanisms underlying the function of two proto-oncogene products.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Turner, R -- Tjian, R -- New York, N.Y. -- Science. 1989 Mar 31;243(4899):1689-94.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Biochemistry, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2494701" target="_blank"〉PubMed〈/a〉

Micromolar concentrations of pyrimidine oligodeoxyribonucleotides are shown to block recognition of double helical DNA by prokaryotic modifying enzymes and a eukaryotic transcription factor at a homopurine target site. Inhibition is sequence-specific. Oligonucleotides containing 5-methylcytosine provide substantially more efficient inhibition than oligonucleotides containing cytosine. The results have implications for gene-specific repression by oligonucleotides or their analogs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maher, L J 3rd -- Wold, B -- Dervan, P B -- New York, N.Y. -- Science. 1989 Aug 18;245(4919):725-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2549631" target="_blank"〉PubMed〈/a〉

    Description: Recombinant DNA clones containing large pieces of DNA are useful in the study of large genetic units, but these are difficult to make in most bacterial cloning vectors. A strategy is described that uses general and site-specific recombination to construct large pieces of eukaryotic DNA from smaller cloned segments. The large clones are propagated on F factor-based plasmids in Escherichia coli. They can be easily modified to introduce mutations or rearrangements. These techniques were applied to the construction of large DNA segments from the bithorax complex of Drosophila.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Connor, M -- Peifer, M -- Bender, W -- New York, N.Y. -- Science. 1989 Jun 16;244(4910):1307-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry and Molecular Pharmacology, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2660262" target="_blank"〉PubMed〈/a〉

    Description: The protein products of the fos and jun proto-oncogenes form a heterodimeric complex that participates in a stable high affinity interaction with DNA elements containing AP-1 binding sites. The effects of deletions and point mutations in Fos and Jun on protein complex formation and DNA binding have been examined. The data suggest that Fos and Jun dimerize via a parallel interaction of helical domains containing a heptad repeat of leucine residues (the leucine zipper). Dimerization is required for DNA binding and results in the appropriate juxtaposition of basic amino acid regions from Fos and Jun, both of which are required for association with DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gentz, R -- Rauscher, F J 3rd -- Abate, C -- Curran, T -- New York, N.Y. -- Science. 1989 Mar 31;243(4899):1695-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Oncology, Roche Institute of Molecular Biology, Nutley, NJ 07110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2494702" target="_blank"〉PubMed〈/a〉

    Description: A true Bronsted analysis of proton transfer in an enzyme mechanism is made possible by the chemical rescue of an inactive mutant of aspartate aminotransferase, where the endogenous general base, Lys258, is replaced with Ala by site-directed mutagenesis. Catalytic activity is restored to this inactive mutant by exogenous amines. The eleven amines studied generate a Bronsted correlation with beta of 0.4 for the transamination of cysteine sulfinate, when steric effects are included in the regression analysis. Localized mutagenesis thus allows the classical Bronsted analysis of transition-state structure to be applied to enzyme-catalyzed reactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Toney, M D -- Kirsch, J F -- GM07232/GM/NIGMS NIH HHS/ -- GM35393/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Mar 17;243(4897):1485-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2538921" target="_blank"〉PubMed〈/a〉

    Description: Filamentous fungi are important in medicine, industry, agriculture, and basic biological research. For example, some fungal species are pathogenic to humans, whereas others produce beta-lactam antibiotics (penicillin and cephalosporin). Industrial strains produce large amounts of enzymes, such as glucoamylase and proteases, and low molecular weight compounds, such as citric acid. The largest and most economically important group of plant pathogens are fungi. Several fungal species have biological properties and genetic systems that make them ideally suited for basic biological research. Recently developed techniques for genetic engineering of filamentous fungi make it possible to alter their detrimental and beneficial activities in novel ways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Timberlake, W E -- Marshall, M A -- New York, N.Y. -- Science. 1989 Jun 16;244(4910):1313-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, University of Georgia, Athens 30602.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2525275" target="_blank"〉PubMed〈/a〉

    Description: The interleukin-2 receptor alpha (IL-2R alpha) chain gene contains a sequence similar to the immunoglobulin (Ig) kappa (kappa) enhancer NF-kappa B binding site. This site, which is bound by the nuclear protein, NF-kappa B, is critical for Ig kappa gene expression. The major T cell nuclear factor that binds to the IL-2R alpha site in vitro appears indistinguishable from NF-kappa B. NF-kappa B binds to IL-2R alpha and kappa sequences with similar affinities; however, only the kappa site potently activates transcription from heterologous promoters. Thus, high-affinity NF-kappa B binding in vitro cannot be equated with transcriptional activation in vivo. Mutation of the NF-kappa B binding site in the context of an IL-2 R alpha promoter construct markedly diminished promoter activity in human T cell lymphotropic virus type I (HTLV-I)-transformed MT-2 cells but not in phorbol myristate acetate-stimulated Jurkat T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cross, S L -- Halden, N F -- Lenardo, M J -- Leonard, W J -- New York, N.Y. -- Science. 1989 Apr 28;244(4903):466-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cell Biology and Metabolism Branch, National Institute of Child Health and Human Development, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2497520" target="_blank"〉PubMed〈/a〉

    Description: Membrane fusion induced by the envelope glycoproteins of human and simian immunodeficiency viruses (HIV and SIVmac) is a necessary step for the infection of CD4 cells and for the formation of syncytia after infection. Identification of the region in these molecules that mediates the fusion events is important for understanding and possibly interfering with HIV/SIVmac infection and pathogenesis. Amino acid substitutions were made in the 15 NH2-terminal residues of the SIVmac gp32 transmembrane glycoprotein, and the mutants were expressed in recombinant vaccinia viruses, which were then used to infect CD4-expressing T cell lines. Mutations that increased the overall hydrophobicity of the gp32 NH2-terminus increased the ability of the viral envelope to induce syncytia formation, whereas introduction of polar or charged amino acids in the same region abolished the fusogenic function of the viral envelope. Hydrophobicity in the NH2-terminal region of gp32 may therefore be an important correlate of viral virulence in vivo and could perhaps be exploited to generate a more effective animal model for the study of acquired immunodeficiency syndrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bosch, M L -- Earl, P L -- Fargnoli, K -- Picciafuoco, S -- Giombini, F -- Wong-Staal, F -- Franchini, G -- New York, N.Y. -- Science. 1989 May 12;244(4905):694-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2541505" target="_blank"〉PubMed〈/a〉

    Description: The genetic control of neuronal differentiation has been studied by examining mutations that affect the development and function of the six touch receptor neurons of the nematode Caenorhabditis elegans. By screening for touch-insensitive mutants, it has been possible to identify 18 genes (represented by 417 mutations) that are required at various stages in the developmental program for touch cell differentiation. Two of the genes are needed for the generation of precursors in the touch cell lineages; without the precursors, touch cells are not made. A third gene, mec-3, specifies the differentiation of the touch cells, probably by acting as a transcription factor. The remaining 15 genes are likely targets of mec-3 action; mutants defective in these genes have nonfunctioning, yet differentiated, touch cells. Some of these latter genes are needed for the formation of cell-specific components of the touch cells, such as a set of microtubules that are only found in these cells. The study of the touch genes should help us understand how touch cell fate is determined, how microtubule form is specified, and, perhaps, how mechanical stimuli are transduced.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chalfie, M -- Au, M -- GM30997/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 24;243(4894 Pt 1):1027-33.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Columbia University, New York, NY 10027.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2646709" target="_blank"〉PubMed〈/a〉

    Description: Expression of high levels of the structural proteins of the human immunodeficiency virus type 1 (HIV-1) requires the presence of the protein encoded by the rev open reading frame (Rev) and its associated target sequence CAR (cis anti-repression sequence) which is present in the env region of viral RNA. Extensive mutagenesis demonstrated that CAR has a complex secondary structure consisting of a central stem and five stem/loops. Disruption of any of these structures severely impaired the Rev response, but many of the stem/loops contain material that was unnecessary for Rev regulation and must be retained in these structures to avoid disturbing adjacent structures critical for CAR function. Probably no more than two of the described structural components are involved in sequence-specific recognition by regulatory proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dayton, E T -- Powell, D M -- Dayton, A I -- New York, N.Y. -- Science. 1989 Dec 22;246(4937):1625-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunoregulation, National Institute of Allergy and Infectious Disease, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2688093" target="_blank"〉PubMed〈/a〉
