    Description: Stabilization of the hypoxia-inducible factor 1 (HIF-1) increases life span and health span in nematodes through an unknown mechanism. We report that neuronal stabilization of HIF-1 mediates these effects in Caenorhabditis elegans through a cell nonautonomous signal to the intestine, which results in activation of the xenobiotic detoxification enzyme flavin-containing monooxygenase-2 (FMO-2). This prolongevity signal requires the serotonin biosynthetic enzyme TPH-1 in neurons and the serotonin receptor SER-7 in the intestine. Intestinal FMO-2 is also activated by dietary restriction (DR) and is necessary for DR-mediated life-span extension, which suggests that this enzyme represents a point of convergence for two distinct longevity pathways. FMOs are conserved in eukaryotes and induced by multiple life span-extending interventions in mice, which suggests that these enzymes may play a critical role in promoting health and longevity across phyla.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leiser, Scott F -- Miller, Hillary -- Rossner, Ryan -- Fletcher, Marissa -- Leonard, Alison -- Primitivo, Melissa -- Rintala, Nicholas -- Ramos, Fresnida J -- Miller, Dana L -- Kaeberlein, Matt -- P30AG013280/AG/NIA NIH HHS/ -- R00AGA0033050/PHS HHS/ -- R01AG038518/AG/NIA NIH HHS/ -- T32AG000057/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2015 Dec 11;350(6266):1375-8. doi: 10.1126/science.aac9257.

    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: Hawks et al. argue that our analysis of Australopithecus sediba mandibles is flawed and that specimen LD 350-1 cannot be distinguished from this, or any other, Australopithecus species. Our reexamination of the evidence confirms that LD 350-1 falls outside of the pattern that A. sediba shares with Australopithecus and thus is reasonably assigned to the genus Homo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Villmoare, Brian -- Kimbel, William H -- Seyoum, Chalachew -- Campisano, Christopher J -- DiMaggio, Erin -- Rowan, John -- Braun, David R -- Arrowsmith, J Ramon -- Reed, Kaye E -- New York, N.Y. -- Science. 2015 Jun 19;348(6241):1326. doi: 10.1126/science.aab1122.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, University of Nevada Las Vegas, Las Vegas, NV, 89154, USA.

    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: Our understanding of the origin of the genus Homo has been hampered by a limited fossil record in eastern Africa between 2.0 and 3.0 million years ago (Ma). Here we report the discovery of a partial hominin mandible with teeth from the Ledi-Geraru research area, Afar Regional State, Ethiopia, that establishes the presence of Homo at 2.80 to 2.75 Ma. This specimen combines primitive traits seen in early Australopithecus with derived morphology observed in later Homo, confirming that dentognathic departures from the australopith pattern occurred early in the Homo lineage. The Ledi-Geraru discovery has implications for hypotheses about the timing and place of origin of the genus Homo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Villmoare, Brian -- Kimbel, William H -- Seyoum, Chalachew -- Campisano, Christopher J -- DiMaggio, Erin N -- Rowan, John -- Braun, David R -- Arrowsmith, J Ramon -- Reed, Kaye E -- New York, N.Y. -- Science. 2015 Mar 20;347(6228):1352-5. doi: 10.1126/science.aaa1343.

    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: Lysosomes are crucial cellular organelles for human health that function in digestion and recycling of extracellular and intracellular macromolecules. We describe a signaling role for lysosomes that affects aging. In the worm Caenorhabditis elegans, the lysosomal acid lipase LIPL-4 triggered nuclear translocalization of a lysosomal lipid chaperone LBP-8, which promoted longevity by activating the nuclear hormone receptors NHR-49 and NHR-80. We used high-throughput metabolomic analysis to identify several lipids in which abundance was increased in worms constitutively overexpressing LIPL-4. Among them, oleoylethanolamide directly bound to LBP-8 and NHR-80 proteins, activated transcription of target genes of NHR-49 and NHR-80, and promoted longevity in C. elegans. These findings reveal a lysosome-to-nucleus signaling pathway that promotes longevity and suggest a function of lysosomes as signaling organelles in metazoans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4425353/" 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/PMC4425353/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Folick, Andrew -- Oakley, Holly D -- Yu, Yong -- Armstrong, Eric H -- Kumari, Manju -- Sanor, Lucas -- Moore, David D -- Ortlund, Eric A -- Zechner, Rudolf -- Wang, Meng C -- F30 AG046043/AG/NIA NIH HHS/ -- F30AG046043/AG/NIA NIH HHS/ -- R00 AG034988/AG/NIA NIH HHS/ -- R00AG034988/AG/NIA NIH HHS/ -- R01 AG045183/AG/NIA NIH HHS/ -- R01 DK095750/DK/NIDDK NIH HHS/ -- R01AG045183/AG/NIA NIH HHS/ -- R01DK095750/DK/NIDDK NIH HHS/ -- T32 GM008602/GM/NIGMS NIH HHS/ -- T32GM008602/GM/NIGMS NIH HHS/ -- T32HD055200/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2015 Jan 2;347(6217):83-6. doi: 10.1126/science.1258857.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Developmental Biology, Baylor College of Medicine, Houston, TX 77030, USA. ; Huffington Center on Aging, Baylor College of Medicine, Houston, TX 77030, USA.

    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: Wireless deep brain stimulation of well-defined neuronal populations could facilitate the study of intact brain circuits and the treatment of neurological disorders. Here, we demonstrate minimally invasive and remote neural excitation through the activation of the heat-sensitive capsaicin receptor TRPV1 by magnetic nanoparticles. When exposed to alternating magnetic fields, the nanoparticles dissipate heat generated by hysteresis, triggering widespread and reversible firing of TRPV1(+) neurons. Wireless magnetothermal stimulation in the ventral tegmental area of mice evoked excitation in subpopulations of neurons in the targeted brain region and in structures receiving excitatory projections. The nanoparticles persisted in the brain for over a month, allowing for chronic stimulation without the need for implants and connectors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Ritchie -- Romero, Gabriela -- Christiansen, Michael G -- Mohr, Alan -- Anikeeva, Polina -- New York, N.Y. -- Science. 2015 Mar 27;347(6229):1477-80. doi: 10.1126/science.1261821.

    Description: A challenge of synthetic biology is the creation of cooperative microbial systems that exhibit population-level behaviors. Such systems use cellular signaling mechanisms to regulate gene expression across multiple cell types. We describe the construction of a synthetic microbial consortium consisting of two distinct cell types-an "activator" strain and a "repressor" strain. These strains produced two orthogonal cell-signaling molecules that regulate gene expression within a synthetic circuit spanning both strains. The two strains generated emergent, population-level oscillations only when cultured together. Certain network topologies of the two-strain circuit were better at maintaining robust oscillations than others. The ability to program population-level dynamics through the genetic engineering of multiple cooperative strains points the way toward engineering complex synthetic tissues and organs with multiple cell types.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4597888/" 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/PMC4597888/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Ye -- Kim, Jae Kyoung -- Hirning, Andrew J -- Josic, Kresimir -- Bennett, Matthew R -- R01 GM104974/GM/NIGMS NIH HHS/ -- R01GM104974/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Aug 28;349(6251):986-9. doi: 10.1126/science.aaa3794.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biosciences, Rice University, Houston, TX 77005, USA. ; Department of Mathematical Sciences, Korea Advanced Institute of Science and Technology, Daejeon 305-701, Korea.

    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: Mammoths provide a detailed example of species origins and dispersal, but understanding has been impeded by taxonomic confusion, especially in North America. The Columbian mammoth Mammuthus columbi was thought to have evolved in North America from a more primitive Eurasian immigrant. The earliest American mammoths (1.5 million years ago), however, resemble the advanced Eurasian M. trogontherii that crossed the Bering land bridge around that time, giving rise directly to M. columbi. Woolly mammoth M. primigenius later evolved in Beringia and spread into Europe and North America, leading to a diversity of morphologies as it encountered endemic M. trogontherii and M. columbi, respectively. In North America, this included intermediates ("M. jeffersonii"), suggesting introgression of M. primigenius with M. columbi. The lineage illustrates the dynamic interplay of local adaptation, dispersal, and gene flow in the evolution of a widely distributed species complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lister, A M -- Sher, A V -- New York, N.Y. -- Science. 2015 Nov 13;350(6262):805-9. doi: 10.1126/science.aac5660.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, Natural History Museum, London SW7 5BD, UK. a.lister@nhm.ac.uk. ; Severtsov Institute of Ecology and Evolution, Moscow 119071, Russia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26564853" target="_blank"〉PubMed〈/a〉

    Description: The mechanistic target of rapamycin complex 1 (mTORC1) protein kinase is a master growth regulator that responds to multiple environmental cues. Amino acids stimulate, in a Rag-, Ragulator-, and vacuolar adenosine triphosphatase-dependent fashion, the translocation of mTORC1 to the lysosomal surface, where it interacts with its activator Rheb. Here, we identify SLC38A9, an uncharacterized protein with sequence similarity to amino acid transporters, as a lysosomal transmembrane protein that interacts with the Rag guanosine triphosphatases (GTPases) and Ragulator in an amino acid-sensitive fashion. SLC38A9 transports arginine with a high Michaelis constant, and loss of SLC38A9 represses mTORC1 activation by amino acids, particularly arginine. Overexpression of SLC38A9 or just its Ragulator-binding domain makes mTORC1 signaling insensitive to amino acid starvation but not to Rag activity. Thus, SLC38A9 functions upstream of the Rag GTPases and is an excellent candidate for being an arginine sensor for the mTORC1 pathway.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4295826/" 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/PMC4295826/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Shuyu -- Tsun, Zhi-Yang -- Wolfson, Rachel L -- Shen, Kuang -- Wyant, Gregory A -- Plovanich, Molly E -- Yuan, Elizabeth D -- Jones, Tony D -- Chantranupong, Lynne -- Comb, William -- Wang, Tim -- Bar-Peled, Liron -- Zoncu, Roberto -- Straub, Christoph -- Kim, Choah -- Park, Jiwon -- Sabatini, Bernardo L -- Sabatini, David M -- AI47389/AI/NIAID NIH HHS/ -- F30 CA180754/CA/NCI NIH HHS/ -- F31 AG044064/AG/NIA NIH HHS/ -- F31 CA180271/CA/NCI NIH HHS/ -- R01 CA103866/CA/NCI NIH HHS/ -- R37 AI047389/AI/NIAID NIH HHS/ -- T32 GM007287/GM/NIGMS NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jan 9;347(6218):188-94. doi: 10.1126/science.1257132.

    Description: During virus infection, the adaptor proteins MAVS and STING transduce signals from the cytosolic nucleic acid sensors RIG-I and cGAS, respectively, to induce type I interferons (IFNs) and other antiviral molecules. Here we show that MAVS and STING harbor two conserved serine and threonine clusters that are phosphorylated by the kinases IKK and/or TBK1 in response to stimulation. Phosphorylated MAVS and STING then bind to a positively charged surface of interferon regulatory factor 3 (IRF3) and thereby recruit IRF3 for its phosphorylation and activation by TBK1. We further show that TRIF, an adaptor protein in Toll-like receptor signaling, activates IRF3 through a similar phosphorylation-dependent mechanism. These results reveal that phosphorylation of innate adaptor proteins is an essential and conserved mechanism that selectively recruits IRF3 to activate the type I IFN pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Siqi -- Cai, Xin -- Wu, Jiaxi -- Cong, Qian -- Chen, Xiang -- Li, Tuo -- Du, Fenghe -- Ren, Junyao -- Wu, You-Tong -- Grishin, Nick V -- Chen, Zhijian J -- AI-93967/AI/NIAID NIH HHS/ -- GM-094575/GM/NIGMS NIH HHS/ -- GM-63692/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Mar 13;347(6227):aaa2630. doi: 10.1126/science.aaa2630.

    Description: Secretion of the cytokine interleukin-1beta (IL-1beta) by macrophages, a major driver of pathogenesis in atherosclerosis, requires two steps: Priming signals promote transcription of immature IL-1beta, and then endogenous "danger" signals activate innate immune signaling complexes called inflammasomes to process IL-1beta for secretion. Although cholesterol crystals are known to act as danger signals in atherosclerosis, what primes IL-1beta transcription remains elusive. Using a murine model of atherosclerosis, we found that cholesterol crystals acted both as priming and danger signals for IL-1beta production. Cholesterol crystals triggered neutrophils to release neutrophil extracellular traps (NETs). NETs primed macrophages for cytokine release, activating T helper 17 (TH17) cells that amplify immune cell recruitment in atherosclerotic plaques. Therefore, danger signals may drive sterile inflammation, such as that seen in atherosclerosis, through their interactions with neutrophils.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warnatsch, Annika -- Ioannou, Marianna -- Wang, Qian -- Papayannopoulos, Venizelos -- MC_UP_1202/13/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 Jul 17;349(6245):316-20. doi: 10.1126/science.aaa8064.

    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: Rgs2, a regulator of G proteins, lowers blood pressure by decreasing signaling through Galphaq. Human patients expressing Met-Leu-Rgs2 (ML-Rgs2) or Met-Arg-Rgs2 (MR-Rgs2) are hypertensive relative to people expressing wild-type Met-Gln-Rgs2 (MQ-Rgs2). We found that wild-type MQ-Rgs2 and its mutant, MR-Rgs2, were destroyed by the Ac/N-end rule pathway, which recognizes N(alpha)-terminally acetylated (Nt-acetylated) proteins. The shortest-lived mutant, ML-Rgs2, was targeted by both the Ac/N-end rule and Arg/N-end rule pathways. The latter pathway recognizes unacetylated N-terminal residues. Thus, the Nt-acetylated Ac-MX-Rgs2 (X = Arg, Gln, Leu) proteins are specific substrates of the mammalian Ac/N-end rule pathway. Furthermore, the Ac/N-degron of Ac-MQ-Rgs2 was conditional, and Teb4, an endoplasmic reticulum (ER) membrane-embedded ubiquitin ligase, was able to regulate G protein signaling by targeting Ac-MX-Rgs2 proteins for degradation through their N(alpha)-terminal acetyl group.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4748709/" 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/PMC4748709/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Park, Sang-Eun -- Kim, Jeong-Mok -- Seok, Ok-Hee -- Cho, Hanna -- Wadas, Brandon -- Kim, Seon-Young -- Varshavsky, Alexander -- Hwang, Cheol-Sang -- DK039520/DK/NIDDK NIH HHS/ -- GM031530/GM/NIGMS NIH HHS/ -- R01 DK039520/DK/NIDDK NIH HHS/ -- R01 GM031530/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Mar 13;347(6227):1249-52. doi: 10.1126/science.aaa3844.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Life Sciences, Pohang University of Science and Technology, Pohang, Gyeongbuk 790-784, South Korea. ; Division of Biology and Biological Engineering, California Institute of Technology, Pasadena, CA 91125, USA. ; Medical Genomics Research Center, KRIBB, Daejeon, South Korea.

    Description: Miocene small-bodied anthropoid primates from Africa and Eurasia are generally considered to precede the divergence between the two groups of extant catarrhines-hominoids (apes and humans) and Old World monkeys-and are thus viewed as more primitive than the stem ape Proconsul. Here we describe Pliobates cataloniae gen. et sp. nov., a small-bodied (4 to 5 kilograms) primate from the Iberian Miocene (11.6 million years ago) that displays a mosaic of primitive characteristics coupled with multiple cranial and postcranial shared derived features of extant hominoids. Our cladistic analyses show that Pliobates is a stem hominoid that is more derived than previously described small catarrhines and Proconsul. This forces us to reevaluate the role played by small-bodied catarrhines in ape evolution and provides key insight into the last common ancestor of hylobatids (gibbons) and hominids (great apes and humans).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alba, David M -- Almecija, Sergio -- DeMiguel, Daniel -- Fortuny, Josep -- Perez de los Rios, Miriam -- Pina, Marta -- Robles, Josep M -- Moya-Sola, Salvador -- New York, N.Y. -- Science. 2015 Oct 30;350(6260):aab2625. doi: 10.1126/science.aab2625.

    Description: The hippocampus computes diverse information involving spatial memory, anxiety, or reward and directly projects to several brain areas. Are different computations transmitted to all downstream targets uniformly, or does the hippocampus selectively route information according to content and target region? By recording from ventral hippocampal CA1 neurons in rats during different behavioral tasks and determining axonal projections with optogenetics, we observed subsets of neurons changing firing at places of elevated anxiety or changing activity during goal approach. Anxiety-related firing was selectively increased in neurons projecting to the prefrontal cortex. Goal-directed firing was most prominent in neurons targeting the nucleus accumbens; and triple-projecting neurons, targeting the prefrontal cortex, amygdala, and nucleus accumbens, were most active during tasks and sharp wave/ripples. Thus, hippocampal neurons route distinct behavior-contingent information selectively to different target areas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ciocchi, S -- Passecker, J -- Malagon-Vina, H -- Mikus, N -- Klausberger, T -- New York, N.Y. -- Science. 2015 May 1;348(6234):560-3. doi: 10.1126/science.aaa3245.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Brain Research, Department for Cognitive Neurobiology, Medical University Vienna, Spitalgasse 4, 1090 Vienna, Austria. stephane.ciocchi@meduniwien.ac.at thomas.klausberger@meduniwien.ac.at. ; Center for Brain Research, Department for Cognitive Neurobiology, Medical University Vienna, Spitalgasse 4, 1090 Vienna, Austria. ; Center for Brain Research, Department for Cognitive Neurobiology, Medical University Vienna, Spitalgasse 4, 1090 Vienna, Austria.

    Description: The ocean moderates anthropogenic climate change at the cost of profound alterations of its physics, chemistry, ecology, and services. Here, we evaluate and compare the risks of impacts on marine and coastal ecosystems-and the goods and services they provide-for growing cumulative carbon emissions under two contrasting emissions scenarios. The current emissions trajectory would rapidly and significantly alter many ecosystems and the associated services on which humans heavily depend. A reduced emissions scenario-consistent with the Copenhagen Accord's goal of a global temperature increase of less than 2 degrees C-is much more favorable to the ocean but still substantially alters important marine ecosystems and associated goods and services. The management options to address ocean impacts narrow as the ocean warms and acidifies. Consequently, any new climate regime that fails to minimize ocean impacts would be incomplete and inadequate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gattuso, J-P -- Magnan, A -- Bille, R -- Cheung, W W L -- Howes, E L -- Joos, F -- Allemand, D -- Bopp, L -- Cooley, S R -- Eakin, C M -- Hoegh-Guldberg, O -- Kelly, R P -- Portner, H-O -- Rogers, A D -- Baxter, J M -- Laffoley, D -- Osborn, D -- Rankovic, A -- Rochette, J -- Sumaila, U R -- Treyer, S -- Turley, C -- New York, N.Y. -- Science. 2015 Jul 3;349(6243):aac4722. doi: 10.1126/science.aac4722.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire d'Oceanographie de Villefranche, CNRS-Institut National des Sciences de l'Univers, F-06230 Villefranche-sur-mer, France.

    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: Notch receptors guide mammalian cell fate decisions by engaging the proteins Jagged and Delta-like (DLL). The 2.3 angstrom resolution crystal structure of the interacting regions of the Notch1-DLL4 complex reveals a two-site, antiparallel binding orientation assisted by Notch1 O-linked glycosylation. Notch1 epidermal growth factor-like repeats 11 and 12 interact with the DLL4 Delta/Serrate/Lag-2 (DSL) domain and module at the N-terminus of Notch ligands (MNNL) domains, respectively. Threonine and serine residues on Notch1 are functionalized with O-fucose and O-glucose, which act as surrogate amino acids by making specific, and essential, contacts to residues on DLL4. The elucidation of a direct chemical role for O-glycans in Notch1 ligand engagement demonstrates how, by relying on posttranslational modifications of their ligand binding sites, Notch proteins have linked their functional capacity to developmentally regulated biosynthetic pathways.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4445638/" 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/PMC4445638/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Luca, Vincent C -- Jude, Kevin M -- Pierce, Nathan W -- Nachury, Maxence V -- Fischer, Suzanne -- Garcia, K Christopher -- 1R01-GM097015/GM/NIGMS NIH HHS/ -- R01 GM097015/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):847-53. doi: 10.1126/science.1261093.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Stanford University School of Medicine, Stanford, CA 94305, USA.

    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: A new Late Jurassic docodontan shows specializations for a subterranean lifestyle. It is similar to extant subterranean golden moles in having reduced digit segments as compared to the ancestral phalangeal pattern of mammaliaforms and extant mammals. The reduction of digit segments can occur in mammals by fusion of the proximal and intermediate phalangeal precursors, a developmental process for which a gene and signaling network have been characterized in mouse and human. Docodontans show a positional shift of thoracolumbar ribs, a developmental variation that is controlled by Hox9 and Myf5 genes in extant mammals. We argue that these morphogenetic mechanisms of modern mammals were operating before the rise of modern mammals, driving the morphological disparity in the earliest mammaliaform diversification.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Luo, Zhe-Xi -- Meng, Qing-Jin -- Ji, Qiang -- Liu, Di -- Zhang, Yu-Guang -- Neander, April I -- New York, N.Y. -- Science. 2015 Feb 13;347(6223):760-4. doi: 10.1126/science.1260880.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismal Biology and Anatomy, University of Chicago, Chicago, IL 60637, USA. zxluo@uchicago.edu mengqingjin@bmnh.org.cn. ; Beijing Museum of Natural History, Beijing 100050, China. zxluo@uchicago.edu mengqingjin@bmnh.org.cn. ; Institute of Geology, Chinese Academy of Geological Sciences, Beijing 100037, China. ; Beijing Museum of Natural History, Beijing 100050, China. ; Department of Organismal Biology and Anatomy, University of Chicago, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25678660" target="_blank"〉PubMed〈/a〉

    Description: The distinctly human ability for forceful precision and power "squeeze" gripping is linked to two key evolutionary transitions in hand use: a reduction in arboreal climbing and the manufacture and use of tools. However, it is unclear when these locomotory and manipulative transitions occurred. Here we show that Australopithecus africanus (~3 to 2 million years ago) and several Pleistocene hominins, traditionally considered not to have engaged in habitual tool manufacture, have a human-like trabecular bone pattern in the metacarpals consistent with forceful opposition of the thumb and fingers typically adopted during tool use. These results support archaeological evidence for stone tool use in australopiths and provide morphological evidence that Pliocene hominins achieved human-like hand postures much earlier and more frequently than previously considered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Skinner, Matthew M -- Stephens, Nicholas B -- Tsegai, Zewdi J -- Foote, Alexandra C -- Nguyen, N Huynh -- Gross, Thomas -- Pahr, Dieter H -- Hublin, Jean-Jacques -- Kivell, Tracy L -- New York, N.Y. -- Science. 2015 Jan 23;347(6220):395-9. doi: 10.1126/science.1261735.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Anthropology and Conservation, University of Kent, Canterbury CT2 7NR, UK.

    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: Navigation depends on multiple neural systems that encode the moment-to-moment changes in an animal's direction and location in space. These include head direction (HD) cells representing the orientation of the head and grid cells that fire at multiple locations, forming a repeating hexagonal grid pattern. Computational models hypothesize that generation of the grid cell signal relies upon HD information that ascends to the hippocampal network via the anterior thalamic nuclei (ATN). We inactivated or lesioned the ATN and subsequently recorded single units in the entorhinal cortex and parasubiculum. ATN manipulation significantly disrupted grid and HD cell characteristics while sparing theta rhythmicity in these regions. These results indicate that the HD signal via the ATN is necessary for the generation and function of grid cell activity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4476794/" 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/PMC4476794/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winter, Shawn S -- Clark, Benjamin J -- Taube, Jeffrey S -- NS053907/NS/NINDS NIH HHS/ -- R01 MH048924/MH/NIMH NIH HHS/ -- R01 NS053907/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):870-4. doi: 10.1126/science.1259591.

    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: Although it is generally accepted that cellular differentiation requires changes to transcriptional networks, dynamic regulation of promoters and enhancers at specific sets of genes has not been previously studied en masse. Exploiting the fact that active promoters and enhancers are transcribed, we simultaneously measured their activity in 19 human and 14 mouse time courses covering a wide range of cell types and biological stimuli. Enhancer RNAs, then messenger RNAs encoding transcription factors, dominated the earliest responses. Binding sites for key lineage transcription factors were simultaneously overrepresented in enhancers and promoters active in each cellular system. Our data support a highly generalizable model in which enhancer transcription is the earliest event in successive waves of transcriptional change during cellular differentiation or activation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4681433/" 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/PMC4681433/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arner, Erik -- Daub, Carsten O -- Vitting-Seerup, Kristoffer -- Andersson, Robin -- Lilje, Berit -- Drablos, Finn -- Lennartsson, Andreas -- Ronnerblad, Michelle -- Hrydziuszko, Olga -- Vitezic, Morana -- Freeman, Tom C -- Alhendi, Ahmad M N -- Arner, Peter -- Axton, Richard -- Baillie, J Kenneth -- Beckhouse, Anthony -- Bodega, Beatrice -- Briggs, James -- Brombacher, Frank -- Davis, Margaret -- Detmar, Michael -- Ehrlund, Anna -- Endoh, Mitsuhiro -- Eslami, Afsaneh -- Fagiolini, Michela -- Fairbairn, Lynsey -- Faulkner, Geoffrey J -- Ferrai, Carmelo -- Fisher, Malcolm E -- Forrester, Lesley -- Goldowitz, Daniel -- Guler, Reto -- Ha, Thomas -- Hara, Mitsuko -- Herlyn, Meenhard -- Ikawa, Tomokatsu -- Kai, Chieko -- Kawamoto, Hiroshi -- Khachigian, Levon M -- Klinken, S Peter -- Kojima, Soichi -- Koseki, Haruhiko -- Klein, Sarah -- Mejhert, Niklas -- Miyaguchi, Ken -- Mizuno, Yosuke -- Morimoto, Mitsuru -- Morris, Kelly J -- Mummery, Christine -- Nakachi, Yutaka -- Ogishima, Soichi -- Okada-Hatakeyama, Mariko -- Okazaki, Yasushi -- Orlando, Valerio -- Ovchinnikov, Dmitry -- Passier, Robert -- Patrikakis, Margaret -- Pombo, Ana -- Qin, Xian-Yang -- Roy, Sugata -- Sato, Hiroki -- Savvi, Suzana -- Saxena, Alka -- Schwegmann, Anita -- Sugiyama, Daisuke -- Swoboda, Rolf -- Tanaka, Hiroshi -- Tomoiu, Andru -- Winteringham, Louise N -- Wolvetang, Ernst -- Yanagi-Mizuochi, Chiyo -- Yoneda, Misako -- Zabierowski, Susan -- Zhang, Peter -- Abugessaisa, Imad -- Bertin, Nicolas -- Diehl, Alexander D -- Fukuda, Shiro -- Furuno, Masaaki -- Harshbarger, Jayson -- Hasegawa, Akira -- Hori, Fumi -- Ishikawa-Kato, Sachi -- Ishizu, Yuri -- Itoh, Masayoshi -- Kawashima, Tsugumi -- Kojima, Miki -- Kondo, Naoto -- Lizio, Marina -- Meehan, Terrence F -- Mungall, Christopher J -- Murata, Mitsuyoshi -- Nishiyori-Sueki, Hiromi -- Sahin, Serkan -- Nagao-Sato, Sayaka -- Severin, Jessica -- de Hoon, Michiel J L -- Kawai, Jun -- Kasukawa, Takeya -- Lassmann, Timo -- Suzuki, Harukazu -- Kawaji, Hideya -- Summers, Kim M -- Wells, Christine -- FANTOM Consortium -- Hume, David A -- Forrest, Alistair R R -- Sandelin, Albin -- Carninci, Piero -- Hayashizaki, Yoshihide -- P30 CA010815/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Feb 27;347(6225):1010-4. doi: 10.1126/science.1259418.

    Description: In healthy individuals, the intestinal microbiota cannot access the liver, spleen, or other peripheral tissues. Some pathogenic bacteria can reach these sites, however, and can induce a systemic immune response. How such compartmentalization is achieved is unknown. We identify a gut-vascular barrier (GVB) in mice and humans that controls the translocation of antigens into the blood stream and prohibits entry of the microbiota. Salmonella typhimurium can penetrate the GVB in a manner dependent on its pathogenicity island (Spi) 2-encoded type III secretion system and on decreased beta-catenin-dependent signaling in gut endothelial cells. The GVB is modified in celiac disease patients with elevated serum transaminases, which indicates that GVB dismantling may be responsible for liver damage in these patients. Understanding the GVB may provide new insights into the regulation of the gut-liver axis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Spadoni, Ilaria -- Zagato, Elena -- Bertocchi, Alice -- Paolinelli, Roberta -- Hot, Edina -- Di Sabatino, Antonio -- Caprioli, Flavio -- Bottiglieri, Luca -- Oldani, Amanda -- Viale, Giuseppe -- Penna, Giuseppe -- Dejana, Elisabetta -- Rescigno, Maria -- New York, N.Y. -- Science. 2015 Nov 13;350(6262):830-4. doi: 10.1126/science.aad0135.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Oncology, European Institute of Oncology, Milan, Italy. ; The Italian Foundation for Cancer Research (FIRC) Institute of Molecular Oncology (IFOM), Milan, Italy. ; First Department of Medicine, St. Matteo Hospital, University of Pavia, Pavia, Italy. ; Unita Operativa Gastroenterologia ed Endoscopia, Fondazione IRCCS Ca Granda, Ospedale Maggiore Policlinico di Milano, and Dipartimento di Fisiopatologia Medico-Chirurgica e dei Trapianti, Universita degli Studi di Milano, Milan, Italy. ; Department of Pathology and Laboratory Medicine, European Institute of Oncology, Milan, Italy. ; The Italian Foundation for Cancer Research (FIRC) Institute of Molecular Oncology (IFOM), Milan, Italy.

    Description: The 26S proteasome is a key player in eukaryotic protein quality control and in the regulation of numerous cellular processes. Here, we describe quantitative in situ structural studies of this highly dynamic molecular machine in intact hippocampal neurons. We used electron cryotomography with the Volta phase plate, which allowed high fidelity and nanometer precision localization of 26S proteasomes. We undertook a molecular census of single- and double-capped proteasomes and assessed the conformational states of individual complexes. Under the conditions of the experiment-that is, in the absence of proteotoxic stress-only 20% of the 26S proteasomes were engaged in substrate processing. The remainder was in the substrate-accepting ground state. These findings suggest that in the absence of stress, the capacity of the proteasome system is not fully used.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Asano, Shoh -- Fukuda, Yoshiyuki -- Beck, Florian -- Aufderheide, Antje -- Forster, Friedrich -- Danev, Radostin -- Baumeister, Wolfgang -- New York, N.Y. -- Science. 2015 Jan 23;347(6220):439-42. doi: 10.1126/science.1261197.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Structural Biology, Max-Planck Institute of Biochemistry, 82152 Martinsried, Germany. ; Department of Molecular Structural Biology, Max-Planck Institute of Biochemistry, 82152 Martinsried, Germany. baumeist@biochem.mpg.de.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25613890" target="_blank"〉PubMed〈/a〉

    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: Nonalcoholic fatty liver disease (NAFLD) is a major factor in the pathogenesis of type 2 diabetes (T2D) and nonalcoholic steatohepatitis (NASH). The mitochondrial protonophore 2,4 dinitrophenol (DNP) has beneficial effects on NAFLD, insulin resistance, and obesity in preclinical models but is too toxic for clinical use. We developed a controlled-release oral formulation of DNP, called CRMP (controlled-release mitochondrial protonophore), that produces mild hepatic mitochondrial uncoupling. In rat models, CRMP reduced hypertriglyceridemia, insulin resistance, hepatic steatosis, and diabetes. It also normalized plasma transaminase concentrations, ameliorated liver fibrosis, and improved hepatic protein synthetic function in a methionine/choline-deficient rat model of NASH. Chronic treatment with CRMP was not associated with any systemic toxicity. These data offer proof of concept that mild hepatic mitochondrial uncoupling may be a safe and effective therapy for the related epidemics of metabolic syndrome, T2D, and NASH.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4495920/" 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/PMC4495920/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perry, Rachel J -- Zhang, Dongyan -- Zhang, Xian-Man -- Boyer, James L -- Shulman, Gerald I -- P30 DK-34989/DK/NIDDK NIH HHS/ -- P30 DK-45735/DK/NIDDK NIH HHS/ -- P30 DK034989/DK/NIDDK NIH HHS/ -- P30 DK045735/DK/NIDDK NIH HHS/ -- R01 DK-40936/DK/NIDDK NIH HHS/ -- R01 DK040936/DK/NIDDK NIH HHS/ -- R24 DK-085638/DK/NIDDK NIH HHS/ -- T32 DK-101019/DK/NIDDK NIH HHS/ -- U24 DK-059635/DK/NIDDK NIH HHS/ -- UL1 TR-000142/TR/NCATS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Mar 13;347(6227):1253-6. doi: 10.1126/science.aaa0672.

    Description: Neuronal circuits produce self-sustaining sequences of activity patterns, but the precise mechanisms remain unknown. Here we provide evidence for autoassociative dynamics in sequence generation. During sharp-wave ripple (SWR) events, hippocampal neurons express sequenced reactivations, which we show are composed of discrete attractors. Each attractor corresponds to a single location, the representation of which sharpens over the course of several milliseconds, as the reactivation focuses at that location. Subsequently, the reactivation transitions rapidly to a spatially discontiguous location. This alternation between sharpening and transition occurs repeatedly within individual SWRs and is locked to the slow-gamma (25 to 50 hertz) rhythm. These findings support theoretical notions of neural network function and reveal a fundamental discretization in the retrieval of memory in the hippocampus, together with a function for gamma oscillations in the control of attractor dynamics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pfeiffer, Brad E -- Foster, David J -- New York, N.Y. -- Science. 2015 Jul 10;349(6244):180-3. doi: 10.1126/science.aaa9633.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Solomon H.

    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: Snakes are a remarkably diverse and successful group today, but their evolutionary origins are obscure. The discovery of snakes with two legs has shed light on the transition from lizards to snakes, but no snake has been described with four limbs, and the ecology of early snakes is poorly known. We describe a four-limbed snake from the Early Cretaceous (Aptian) Crato Formation of Brazil. The snake has a serpentiform body plan with an elongate trunk, short tail, and large ventral scales suggesting characteristic serpentine locomotion, yet retains small prehensile limbs. Skull and body proportions as well as reduced neural spines indicate fossorial adaptation, suggesting that snakes evolved from burrowing rather than marine ancestors. Hooked teeth, an intramandibular joint, a flexible spine capable of constricting prey, and the presence of vertebrate remains in the guts indicate that this species preyed on vertebrates and that snakes made the transition to carnivory early in their history. The structure of the limbs suggests that they were adapted for grasping, either to seize prey or as claspers during mating. Together with a diverse fauna of basal snakes from the Cretaceous of South America, Africa, and India, this snake suggests that crown Serpentes originated in Gondwana.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martill, David M -- Tischlinger, Helmut -- Longrich, Nicholas R -- New York, N.Y. -- Science. 2015 Jul 24;349(6246):416-9. doi: 10.1126/science.aaa9208.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Earth and Environmental Sciences, University of Portsmouth, Portsmouth PO1 3QL, UK. ; Tannenweg 16, 85134 Stammham, Germany. ; Department of Biology and Biochemistry and Milner Centre for Evolution, University of Bath, Claverton Down, Bath BA2 7AY, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26206932" target="_blank"〉PubMed〈/a〉

    Description: Obligate parasitic plants in the Orobanchaceae germinate after sensing plant hormones, strigolactones, exuded from host roots. In Arabidopsis thaliana, the alpha/beta-hydrolase D14 acts as a strigolactone receptor that controls shoot branching, whereas its ancestral paralog, KAI2, mediates karrikin-specific germination responses. We observed that KAI2, but not D14, is present at higher copy numbers in parasitic species than in nonparasitic relatives. KAI2 paralogs in parasites are distributed into three phylogenetic clades. The fastest-evolving clade, KAI2d, contains the majority of KAI2 paralogs. Homology models predict that the ligand-binding pockets of KAI2d resemble D14. KAI2d transgenes confer strigolactone-specific germination responses to Arabidopsis thaliana. Thus, the KAI2 paralogs D14 and KAI2d underwent convergent evolution of strigolactone recognition, respectively enabling developmental responses to strigolactones in angiosperms and host detection in parasites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Conn, Caitlin E -- Bythell-Douglas, Rohan -- Neumann, Drexel -- Yoshida, Satoko -- Whittington, Bryan -- Westwood, James H -- Shirasu, Ken -- Bond, Charles S -- Dyer, Kelly A -- Nelson, David C -- New York, N.Y. -- Science. 2015 Jul 31;349(6247):540-3. doi: 10.1126/science.aab1140.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, University of Georgia, Athens, GA 30602, USA. ; School of Chemistry and Biochemistry, The University of Western Australia, Crawley, Western Australia 6009, Australia. ; RIKEN Center for Sustainable Resource Science, Tsurumi-ku, Yokohama, Kanagawa 230-0045, Japan. ; Department of Plant Pathology, Physiology, and Weed Science, Virginia Tech, Blacksburg, VA 24061, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26228149" target="_blank"〉PubMed〈/a〉

    Description: Astrocytes are important regulatory elements in brain function. They respond to neurotransmitters and release gliotransmitters that modulate synaptic transmission. However, the cell- and synapse-specificity of the functional relationship between astrocytes and neurons in certain brain circuits remains unknown. In the dorsal striatum, which mainly comprises two intermingled subtypes (striatonigral and striatopallidal) of medium spiny neurons (MSNs) and synapses belonging to two neural circuits (the direct and indirect pathways of the basal ganglia), subpopulations of astrocytes selectively responded to specific MSN subtype activity. These subpopulations of astrocytes released glutamate that selectively activated N-methyl-d-aspartate receptors in homotypic, but not heterotypic, MSNs. Likewise, astrocyte subpopulations selectively regulated homotypic synapses through metabotropic glutamate receptor activation. Therefore, bidirectional astrocyte-neuron signaling selectively occurs between specific subpopulations of astrocytes, neurons, and synapses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, R -- Bajo-Graneras, R -- Moratalla, R -- Perea, G -- Araque, A -- New York, N.Y. -- Science. 2015 Aug 14;349(6249):730-4. doi: 10.1126/science.aaa7945.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Instituto Cajal, Consejo Superior de Investigaciones Cientificas, 28002 Madrid, Spain. ; Instituto Cajal, Consejo Superior de Investigaciones Cientificas, 28002 Madrid, Spain.

    Description: The planetary boundaries framework defines a safe operating space for humanity based on the intrinsic biophysical processes that regulate the stability of the Earth system. Here, we revise and update the planetary boundary framework, with a focus on the underpinning biophysical science, based on targeted input from expert research communities and on more general scientific advances over the past 5 years. Several of the boundaries now have a two-tier approach, reflecting the importance of cross-scale interactions and the regional-level heterogeneity of the processes that underpin the boundaries. Two core boundaries-climate change and biosphere integrity-have been identified, each of which has the potential on its own to drive the Earth system into a new state should they be substantially and persistently transgressed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steffen, Will -- Richardson, Katherine -- Rockstrom, Johan -- Cornell, Sarah E -- Fetzer, Ingo -- Bennett, Elena M -- Biggs, Reinette -- Carpenter, Stephen R -- de Vries, Wim -- de Wit, Cynthia A -- Folke, Carl -- Gerten, Dieter -- Heinke, Jens -- Mace, Georgina M -- Persson, Linn M -- Ramanathan, Veerabhadran -- Reyers, Belinda -- Sorlin, Sverker -- New York, N.Y. -- Science. 2015 Feb 13;347(6223):1259855. doi: 10.1126/science.1259855.

    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: Many top consumers in today's oceans are marine tetrapods, a collection of lineages independently derived from terrestrial ancestors. The fossil record illuminates their transitions from land to sea, yet these initial invasions account for a small proportion of their evolutionary history. We review the history of marine invasions that drove major changes in anatomy, physiology, and ecology over more than 250 million years. Many innovations evolved convergently in multiple clades, whereas others are unique to individual lineages. The evolutionary arcs of these ecologically important clades are framed against the backdrop of mass extinctions and regime shifts in ocean ecosystems. Past and present human disruptions to marine tetrapods, with cascading impacts on marine ecosystems, underscore the need to link macroecology with evolutionary change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelley, Neil P -- Pyenson, Nicholas D -- New York, N.Y. -- Science. 2015 Apr 17;348(6232):aaa3716. doi: 10.1126/science.aaa3716.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Paleobiology, National Museum of Natural History, Smithsonian Institution, Washington, DC 20013, USA.

    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: Marine defaunation, or human-caused animal loss in the oceans, emerged forcefully only hundreds of years ago, whereas terrestrial defaunation has been occurring far longer. Though humans have caused few global marine extinctions, we have profoundly affected marine wildlife, altering the functioning and provisioning of services in every ocean. Current ocean trends, coupled with terrestrial defaunation lessons, suggest that marine defaunation rates will rapidly intensify as human use of the oceans industrializes. Though protected areas are a powerful tool to harness ocean productivity, especially when designed with future climate in mind, additional management strategies will be required. Overall, habitat degradation is likely to intensify as a major driver of marine wildlife loss. Proactive intervention can avert a marine defaunation disaster of the magnitude observed on land.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCauley, Douglas J -- Pinsky, Malin L -- Palumbi, Stephen R -- Estes, James A -- Joyce, Francis H -- Warner, Robert R -- New York, N.Y. -- Science. 2015 Jan 16;347(6219):1255641. doi: 10.1126/science.1255641.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, Evolution, and Marine Biology, University of California, Santa Barbara, CA 93106, USA. douglas.mccauley@lifesci.ucsb.edu. ; Department of Ecology, Evolution, and Natural Resources, Institute of Marine and Coastal Sciences, Rutgers University, New Brunswick, NJ 08901, USA. ; Department of Biology, Stanford University, Hopkins Marine Station, Pacific Grove, CA 93950, USA. ; Department of Ecology and Evolutionary Biology, University of California, Santa Cruz, CA 95060, USA. ; Department of Ecology, Evolution, and Marine Biology, University of California, Santa Barbara, CA 93106, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25593191" target="_blank"〉PubMed〈/a〉

    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: Chatters et al. (Reports, 16 May 2014, p. 750) reported the retrieval of DNA sequences from a 12,000- to 13,000-year-old human tooth discovered in an underwater cave in Mexico's Yucatan peninsula. They propose that this ancient human individual's mitochondrial DNA (mtDNA) belongs to haplogroup D1. However, our analysis of postmortem damage patterns finds no evidence for an ancient origin of these sequences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prufer, Kay -- Meyer, Matthias -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):835. doi: 10.1126/science.1260617.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Evolutionary Anthropology, 04103 Leipzig, Germany. pruefer@eva.mpg.de mmeyer@eva.mpg.de.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25700510" target="_blank"〉PubMed〈/a〉

    Description: Dying cells initiate adaptive immunity by providing both antigens and inflammatory stimuli for dendritic cells, which in turn activate CD8(+) T cells through a process called antigen cross-priming. To define how different forms of programmed cell death influence immunity, we established models of necroptosis and apoptosis, in which dying cells are generated by receptor-interacting protein kinase-3 and caspase-8 dimerization, respectively. We found that the release of inflammatory mediators, such as damage-associated molecular patterns, by dying cells was not sufficient for CD8(+) T cell cross-priming. Instead, robust cross-priming required receptor-interacting protein kinase-1 (RIPK1) signaling and nuclear factor kappaB (NF-kappaB)-induced transcription within dying cells. Decoupling NF-kappaB signaling from necroptosis or inflammatory apoptosis reduced priming efficiency and tumor immunity. Our results reveal that coordinated inflammatory and cell death signaling pathways within dying cells orchestrate adaptive immunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4651449/" 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/PMC4651449/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yatim, Nader -- Jusforgues-Saklani, Helene -- Orozco, Susana -- Schulz, Oliver -- Barreira da Silva, Rosa -- Reis e Sousa, Caetano -- Green, Douglas R -- Oberst, Andrew -- Albert, Matthew L -- 5R01AI108685-02/AI/NIAID NIH HHS/ -- AI44848/AI/NIAID NIH HHS/ -- R01 AI108685/AI/NIAID NIH HHS/ -- R01AI108685/AI/NIAID NIH HHS/ -- R21 CA185681/CA/NCI NIH HHS/ -- R21CA185681/CA/NCI NIH HHS/ -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2015 Oct 16;350(6258):328-34. doi: 10.1126/science.aad0395.

    Description: The inefficient clearance of dying cells can lead to abnormal immune responses, such as unresolved inflammation and autoimmune conditions. We show that tumor suppressor p53 controls signaling-mediated phagocytosis of apoptotic cells through its target, Death Domain1alpha (DD1alpha), which suggests that p53 promotes both the proapoptotic pathway and postapoptotic events. DD1alpha appears to function as an engulfment ligand or receptor that engages in homophilic intermolecular interaction at intercellular junctions of apoptotic cells and macrophages, unlike other typical scavenger receptors that recognize phosphatidylserine on the surface of dead cells. DD1alpha-deficient mice showed in vivo defects in clearing dying cells, which led to multiple organ damage indicative of immune dysfunction. p53-induced expression of DD1alpha thus prevents persistence of cell corpses and ensures efficient generation of precise immune responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoon, Kyoung Wan -- Byun, Sanguine -- Kwon, Eunjeong -- Hwang, So-Young -- Chu, Kiki -- Hiraki, Masatsugu -- Jo, Seung-Hee -- Weins, Astrid -- Hakroush, Samy -- Cebulla, Angelika -- Sykes, David B -- Greka, Anna -- Mundel, Peter -- Fisher, David E -- Mandinova, Anna -- Lee, Sam W -- CA142805/CA/NCI NIH HHS/ -- CA149477/CA/NCI NIH HHS/ -- CA80058/CA/NCI NIH HHS/ -- DK062472/DK/NIDDK NIH HHS/ -- DK091218/DK/NIDDK NIH HHS/ -- DK093378/DK/NIDDK NIH HHS/ -- DK57683/DK/NIDDK NIH HHS/ -- S10RR027673/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2015 Jul 31;349(6247):1261669. doi: 10.1126/science.1261669.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cutaneous Biology Research Center, Massachusetts General Hospital and Harvard Medical School, Building 149, 13th Street, Charlestown, MA 02129, USA. ; Department of Pathology, Brigham and Women's Hospital, and Harvard Medical School, Boston, MA 02115, USA. ; Division of Nephrology, Department of Medicine, Massachusetts General Hospital, Boston, MA 02114, USA. ; Center for Regenerative Medicine and Technology, Massachusetts General Hospital and Harvard Medical School, Boston, MA 02114, USA. ; Department of Medicine, Glom-NExT Center for Glomerular Kidney Disease and Novel Experimental Therapeutics, Brigham and Women's Hospital, and Harvard Medical School, Boston, MA 02115, USA. ; Cutaneous Biology Research Center, Massachusetts General Hospital and Harvard Medical School, Building 149, 13th Street, Charlestown, MA 02129, USA.

    Description: Evolutionary innovations, traits that give species access to previously unoccupied niches, may promote speciation and adaptive radiation. Here, we show that such innovations can also result in competitive inferiority and extinction. We present evidence that the modified pharyngeal jaws of cichlid fishes and several marine fish lineages, a classic example of evolutionary innovation, are not universally beneficial. A large-scale analysis of dietary evolution across marine fish lineages reveals that the innovation compromises access to energy-rich predator niches. We show that this competitive inferiority shaped the adaptive radiation of cichlids in Lake Tanganyika and played a pivotal and previously unrecognized role in the mass extinction of cichlid fishes in Lake Victoria after Nile perch invasion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGee, Matthew D -- Borstein, Samuel R -- Neches, Russell Y -- Buescher, Heinz H -- Seehausen, Ole -- Wainwright, Peter C -- New York, N.Y. -- Science. 2015 Nov 27;350(6264):1077-9. doi: 10.1126/science.aab0800.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Evolution and Ecology and Center for Population Biology, University of California, Davis, CA 95616, USA.

    Description: Alternative splicing (AS) generates extensive transcriptomic and proteomic complexity. However, the functions of species- and lineage-specific splice variants are largely unknown. Here we show that mammalian-specific skipping of polypyrimidine tract-binding protein 1 (PTBP1) exon 9 alters the splicing regulatory activities of PTBP1 and affects the inclusion levels of numerous exons. During neurogenesis, skipping of exon 9 reduces PTBP1 repressive activity so as to facilitate activation of a brain-specific AS program. Engineered skipping of the orthologous exon in chicken cells induces a large number of mammalian-like AS changes in PTBP1 target exons. These results thus reveal that a single exon-skipping event in an RNA binding regulator directs numerous AS changes between species. Our results further suggest that these changes contributed to evolutionary differences in the formation of vertebrate nervous systems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gueroussov, Serge -- Gonatopoulos-Pournatzis, Thomas -- Irimia, Manuel -- Raj, Bushra -- Lin, Zhen-Yuan -- Gingras, Anne-Claude -- Blencowe, Benjamin J -- Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2015 Aug 21;349(6250):868-73. doi: 10.1126/science.aaa8381.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Donnelly Centre, University of Toronto, Toronto, Ontario M5S 3E1, Canada.

    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.
