Description: Infectious and inflammatory diseases have repeatedly shown strong genetic associations within the major histocompatibility complex (MHC); however, the basis for these associations remains elusive. To define host genetic effects on the outcome of a chronic viral infection, we performed genome-wide association analysis in a multiethnic cohort of HIV-1 controllers and progressors, and we analyzed the effects of individual amino acids within the classical human leukocyte antigen (HLA) proteins. We identified 〉300 genome-wide significant single-nucleotide polymorphisms (SNPs) within the MHC and none elsewhere. Specific amino acids in the HLA-B peptide binding groove, as well as an independent HLA-C effect, explain the SNP associations and reconcile both protective and risk HLA alleles. These results implicate the nature of the HLA-viral peptide interaction as the major factor modulating durable control of HIV infection.〈br /〉〈br /〉〈a

Description: The Mars Science Laboratory (MSL) mission is focused on assessing the past or present habitability of Mars, through interrogation of environment and environmental records at the Curiosity rover field site in Gale crater. The MSL team has two methods available to collect, process and deliver samples to onboard analytical laboratories, the Chemistry and Mineralogy instrument (CheMin) and the Sample Analysis at Mars (SAM) instrument suite. One approach obtains samples by drilling into a rock, the other uses a scoop to collect loose regolith fines. Scooping was planned to be first method performed on Mars because materials could be readily scooped multiple times and used to remove any remaining, minute terrestrial contaminants from the sample processing system, the Collection and Handling for In-Situ Martian Rock Analysis (CHIMRA). Because of this cleaning effort, the ideal first material to be scooped would consist of fine to very fine sand, like the interior of the Serpent Dune studied by the Mars Exploration Rover (MER) Spirit team in 2004 [1]. The MSL team selected a linear eolian deposit in the lee of a group of cobbles they named Rocknest (Fig. 1) as likely to be similar to Serpent Dune. Following the definitions in Chapter 13 of Bagnold [2], the deposit is termed a sand shadow. The scooping campaign occurred over approximately 6 weeks in October and November 2012. To support these activities, the Mars Hand Lens Imager (MAHLI) acquired images for engineering support/assessment and scientific inquiry.

Description: Cancers have dysfunctional redox regulation resulting in reactive oxygen species production, damaging both DNA and free dNTPs. The MTH1 protein sanitizes oxidized dNTP pools to prevent incorporation of damaged bases during DNA replication. Although MTH1 is non-essential in normal cells, we show that cancer cells require MTH1 activity to avoid incorporation of oxidized dNTPs, resulting in DNA damage and cell death. We validate MTH1 as an anticancer target in vivo and describe small molecules TH287 and TH588 as first-in-class nudix hydrolase family inhibitors that potently and selectively engage and inhibit the MTH1 protein in cells. Protein co-crystal structures demonstrate that the inhibitors bind in the active site of MTH1. The inhibitors cause incorporation of oxidized dNTPs in cancer cells, leading to DNA damage, cytotoxicity and therapeutic responses in patient-derived mouse xenografts. This study exemplifies the non-oncogene addiction concept for anticancer treatment and validates MTH1 as being cancer phenotypic lethal.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gad, Helge -- Koolmeister, Tobias -- Jemth, Ann-Sofie -- Eshtad, Saeed -- Jacques, Sylvain A -- Strom, Cecilia E -- Svensson, Linda M -- Schultz, Niklas -- Lundback, Thomas -- Einarsdottir, Berglind Osk -- Saleh, Aljona -- Gokturk, Camilla -- Baranczewski, Pawel -- Svensson, Richard -- Berntsson, Ronnie P-A -- Gustafsson, Robert -- Stromberg, Kia -- Sanjiv, Kumar -- Jacques-Cordonnier, Marie-Caroline -- Desroses, Matthieu -- Gustavsson, Anna-Lena -- Olofsson, Roger -- Johansson, Fredrik -- Homan, Evert J -- Loseva, Olga -- Brautigam, Lars -- Johansson, Lars -- Hoglund, Andreas -- Hagenkort, Anna -- Pham, Therese -- Altun, Mikael -- Gaugaz, Fabienne Z -- Vikingsson, Svante -- Evers, Bastiaan -- Henriksson, Martin -- Vallin, Karl S A -- Wallner, Olov A -- Hammarstrom, Lars G J -- Wiita, Elisee -- Almlof, Ingrid -- Kalderen, Christina -- Axelsson, Hanna -- Djureinovic, Tatjana -- Puigvert, Jordi Carreras -- Haggblad, Maria -- Jeppsson, Fredrik -- Martens, Ulf -- Lundin, Cecilia -- Lundgren, Bo -- Granelli, Ingrid -- Jensen, Annika Jenmalm -- Artursson, Per -- Nilsson, Jonas A -- Stenmark, Pal -- Scobie, Martin -- Berglund, Ulrika Warpman -- Helleday, Thomas -- England -- Nature. 2014 Apr 10;508(7495):215-21. doi: 10.1038/nature13181.

Description: X-ray crystallography provides the vast majority of macromolecular structures, but the success of the method relies on growing crystals of sufficient size. In conventional measurements, the necessary increase in X-ray dose to record data from crystals that are too small leads to extensive damage before a diffraction signal can be recorded. It is particularly challenging to obtain large, well-diffracting crystals of membrane proteins, for which fewer than 300 unique structures have been determined despite their importance in all living cells. Here we present a method for structure determination where single-crystal X-ray diffraction 'snapshots' are collected from a fully hydrated stream of nanocrystals using femtosecond pulses from a hard-X-ray free-electron laser, the Linac Coherent Light Source. We prove this concept with nanocrystals of photosystem I, one of the largest membrane protein complexes. More than 3,000,000 diffraction patterns were collected in this study, and a three-dimensional data set was assembled from individual photosystem I nanocrystals ( approximately 200 nm to 2 mum in size). We mitigate the problem of radiation damage in crystallography by using pulses briefer than the timescale of most damage processes. This offers a new approach to structure determination of macromolecules that do not yield crystals of sufficient size for studies using conventional radiation sources or are particularly sensitive to radiation damage.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3429598/" 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/PMC3429598/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chapman, Henry N -- Fromme, Petra -- Barty, Anton -- White, Thomas A -- Kirian, Richard A -- Aquila, Andrew -- Hunter, Mark S -- Schulz, Joachim -- DePonte, Daniel P -- Weierstall, Uwe -- Doak, R Bruce -- Maia, Filipe R N C -- Martin, Andrew V -- Schlichting, Ilme -- Lomb, Lukas -- Coppola, Nicola -- Shoeman, Robert L -- Epp, Sascha W -- Hartmann, Robert -- Rolles, Daniel -- Rudenko, Artem -- Foucar, Lutz -- Kimmel, Nils -- Weidenspointner, Georg -- Holl, Peter -- Liang, Mengning -- Barthelmess, Miriam -- Caleman, Carl -- Boutet, Sebastien -- Bogan, Michael J -- Krzywinski, Jacek -- Bostedt, Christoph -- Bajt, Sasa -- Gumprecht, Lars -- Rudek, Benedikt -- Erk, Benjamin -- Schmidt, Carlo -- Homke, Andre -- Reich, Christian -- Pietschner, Daniel -- Struder, Lothar -- Hauser, Gunter -- Gorke, Hubert -- Ullrich, Joachim -- Herrmann, Sven -- Schaller, Gerhard -- Schopper, Florian -- Soltau, Heike -- Kuhnel, Kai-Uwe -- Messerschmidt, Marc -- Bozek, John D -- Hau-Riege, Stefan P -- Frank, Matthias -- Hampton, Christina Y -- Sierra, Raymond G -- Starodub, Dmitri -- Williams, Garth J -- Hajdu, Janos -- Timneanu, Nicusor -- Seibert, M Marvin -- Andreasson, Jakob -- Rocker, Andrea -- Jonsson, Olof -- Svenda, Martin -- Stern, Stephan -- Nass, Karol -- Andritschke, Robert -- Schroter, Claus-Dieter -- Krasniqi, Faton -- Bott, Mario -- Schmidt, Kevin E -- Wang, Xiaoyu -- Grotjohann, Ingo -- Holton, James M -- Barends, Thomas R M -- Neutze, Richard -- Marchesini, Stefano -- Fromme, Raimund -- Schorb, Sebastian -- Rupp, Daniela -- Adolph, Marcus -- Gorkhover, Tais -- Andersson, Inger -- Hirsemann, Helmut -- Potdevin, Guillaume -- Graafsma, Heinz -- Nilsson, Bjorn -- Spence, John C H -- 1R01GM095583-01/GM/NIGMS NIH HHS/ -- 1U54GM094625-01/GM/NIGMS NIH HHS/ -- R01 GM095583/GM/NIGMS NIH HHS/ -- U54 GM094599/GM/NIGMS NIH HHS/ -- U54 GM094625/GM/NIGMS NIH HHS/ -- England -- Nature. 2011 Feb 3;470(7332):73-7. doi: 10.1038/nature09750.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Free-Electron Laser Science, DESY, Notkestrasse 85, 22607 Hamburg, Germany. henry.chapman@desy.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21293373" target="_blank"〉PubMed〈/a〉

Description: The Trypanosoma brucei cysteine protease cathepsin B (TbCatB), which is involved in host protein degradation, is a promising target to develop new treatments against sleeping sickness, a fatal disease caused by this protozoan parasite. The structure of the mature, active form of TbCatB has so far not provided sufficient information for the design of a safe and specific drug against T. brucei. By combining two recent innovations, in vivo crystallization and serial femtosecond crystallography, we obtained the room-temperature 2.1 angstrom resolution structure of the fully glycosylated precursor complex of TbCatB. The structure reveals the mechanism of native TbCatB inhibition and demonstrates that new biomolecular information can be obtained by the "diffraction-before-destruction" approach of x-ray free-electron lasers from hundreds of thousands of individual microcrystals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3786669/" 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/PMC3786669/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Redecke, Lars -- Nass, Karol -- DePonte, Daniel P -- White, Thomas A -- Rehders, Dirk -- Barty, Anton -- Stellato, Francesco -- Liang, Mengning -- Barends, Thomas R M -- Boutet, Sebastien -- Williams, Garth J -- Messerschmidt, Marc -- Seibert, M Marvin -- Aquila, Andrew -- Arnlund, David -- Bajt, Sasa -- Barth, Torsten -- Bogan, Michael J -- Caleman, Carl -- Chao, Tzu-Chiao -- Doak, R Bruce -- Fleckenstein, Holger -- Frank, Matthias -- Fromme, Raimund -- Galli, Lorenzo -- Grotjohann, Ingo -- Hunter, Mark S -- Johansson, Linda C -- Kassemeyer, Stephan -- Katona, Gergely -- Kirian, Richard A -- Koopmann, Rudolf -- Kupitz, Chris -- Lomb, Lukas -- Martin, Andrew V -- Mogk, Stefan -- Neutze, Richard -- Shoeman, Robert L -- Steinbrener, Jan -- Timneanu, Nicusor -- Wang, Dingjie -- Weierstall, Uwe -- Zatsepin, Nadia A -- Spence, John C H -- Fromme, Petra -- Schlichting, Ilme -- Duszenko, Michael -- Betzel, Christian -- Chapman, Henry N -- 1R01GM095583/GM/NIGMS NIH HHS/ -- R01 GM095583/GM/NIGMS NIH HHS/ -- U54 GM094599/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Jan 11;339(6116):227-30. doi: 10.1126/science.1229663.

Description: MAHLI (Mars Hand Lens Imager) is a 2-megapixel focusable macro lens color camera on the turret on Curiosity's robotic arm. The investigation centers on stratigraphy, grain-scale texture, structure, mineralogy, and morphology of geologic materials at Curiosity's Gale robotic field site. MAHLI acquires focused images at working distances of 2.1 cm to infinity; for reference, at 2.1 cm the scale is 14 microns/pixel; at 6.9 cm it is 31 microns/pixel, like the Spirit and Opportunity Microscopic Imager (MI) cameras.

Description: Glucose homeostasis is a vital and complex process, and its disruption can cause hyperglycaemia and type II diabetes mellitus. Glucokinase (GK), a key enzyme that regulates glucose homeostasis, converts glucose to glucose-6-phosphate in pancreatic beta-cells, liver hepatocytes, specific hypothalamic neurons, and gut enterocytes. In hepatocytes, GK regulates glucose uptake and glycogen synthesis, suppresses glucose production, and is subject to the endogenous inhibitor GK regulatory protein (GKRP). During fasting, GKRP binds, inactivates and sequesters GK in the nucleus, which removes GK from the gluconeogenic process and prevents a futile cycle of glucose phosphorylation. Compounds that directly hyperactivate GK (GK activators) lower blood glucose levels and are being evaluated clinically as potential therapeutics for the treatment of type II diabetes mellitus. However, initial reports indicate that an increased risk of hypoglycaemia is associated with some GK activators. To mitigate the risk of hypoglycaemia, we sought to increase GK activity by blocking GKRP. Here we describe the identification of two potent small-molecule GK-GKRP disruptors (AMG-1694 and AMG-3969) that normalized blood glucose levels in several rodent models of diabetes. These compounds potently reversed the inhibitory effect of GKRP on GK activity and promoted GK translocation both in vitro (isolated hepatocytes) and in vivo (liver). A co-crystal structure of full-length human GKRP in complex with AMG-1694 revealed a previously unknown binding pocket in GKRP distinct from that of the phosphofructose-binding site. Furthermore, with AMG-1694 and AMG-3969 (but not GK activators), blood glucose lowering was restricted to diabetic and not normoglycaemic animals. These findings exploit a new cellular mechanism for lowering blood glucose levels with reduced potential for hypoglycaemic risk in patients with type II diabetes mellitus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lloyd, David J -- St Jean, David J Jr -- Kurzeja, Robert J M -- Wahl, Robert C -- Michelsen, Klaus -- Cupples, Rod -- Chen, Michelle -- Wu, John -- Sivits, Glenn -- Helmering, Joan -- Komorowski, Renee -- Ashton, Kate S -- Pennington, Lewis D -- Fotsch, Christopher -- Vazir, Mukta -- Chen, Kui -- Chmait, Samer -- Zhang, Jiandong -- Liu, Longbin -- Norman, Mark H -- Andrews, Kristin L -- Bartberger, Michael D -- Van, Gwyneth -- Galbreath, Elizabeth J -- Vonderfecht, Steven L -- Wang, Minghan -- Jordan, Steven R -- Veniant, Murielle M -- Hale, Clarence -- England -- Nature. 2013 Dec 19;504(7480):437-40. doi: 10.1038/nature12724.

Description: Achieving the goal of malaria elimination will depend on targeting Plasmodium pathways essential across all life stages. Here we identify a lipid kinase, phosphatidylinositol-4-OH kinase (PI(4)K), as the target of imidazopyrazines, a new antimalarial compound class that inhibits the intracellular development of multiple Plasmodium species at each stage of infection in the vertebrate host. Imidazopyrazines demonstrate potent preventive, therapeutic, and transmission-blocking activity in rodent malaria models, are active against blood-stage field isolates of the major human pathogens P. falciparum and P. vivax, and inhibit liver-stage hypnozoites in the simian parasite P. cynomolgi. We show that imidazopyrazines exert their effect through inhibitory interaction with the ATP-binding pocket of PI(4)K, altering the intracellular distribution of phosphatidylinositol-4-phosphate. Collectively, our data define PI(4)K as a key Plasmodium vulnerability, opening up new avenues of target-based discovery to identify drugs with an ideal activity profile for the prevention, treatment and elimination of malaria.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3940870/" 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/PMC3940870/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McNamara, Case W -- Lee, Marcus C S -- Lim, Chek Shik -- Lim, Siau Hoi -- Roland, Jason -- Nagle, Advait -- Simon, Oliver -- Yeung, Bryan K S -- Chatterjee, Arnab K -- McCormack, Susan L -- Manary, Micah J -- Zeeman, Anne-Marie -- Dechering, Koen J -- Kumar, T R Santha -- Henrich, Philipp P -- Gagaring, Kerstin -- Ibanez, Maureen -- Kato, Nobutaka -- Kuhen, Kelli L -- Fischli, Christoph -- Rottmann, Matthias -- Plouffe, David M -- Bursulaya, Badry -- Meister, Stephan -- Rameh, Lucia -- Trappe, Joerg -- Haasen, Dorothea -- Timmerman, Martijn -- Sauerwein, Robert W -- Suwanarusk, Rossarin -- Russell, Bruce -- Renia, Laurent -- Nosten, Francois -- Tully, David C -- Kocken, Clemens H M -- Glynne, Richard J -- Bodenreider, Christophe -- Fidock, David A -- Diagana, Thierry T -- Winzeler, Elizabeth A -- 078285/Wellcome Trust/United Kingdom -- 089275/Wellcome Trust/United Kingdom -- 090534/Wellcome Trust/United Kingdom -- 096157/Wellcome Trust/United Kingdom -- R01 AI079709/AI/NIAID NIH HHS/ -- R01 AI085584/AI/NIAID NIH HHS/ -- R01 AI090141/AI/NIAID NIH HHS/ -- R01 AI103058/AI/NIAID NIH HHS/ -- R01079709/PHS HHS/ -- R01085584/PHS HHS/ -- R01AI090141/AI/NIAID NIH HHS/ -- WT078285/Wellcome Trust/United Kingdom -- WT096157/Wellcome Trust/United Kingdom -- England -- Nature. 2013 Dec 12;504(7479):248-53. doi: 10.1038/nature12782.

Description: Multiple myeloma is an incurable malignancy of plasma cells, and its pathogenesis is poorly understood. Here we report the massively parallel sequencing of 38 tumour genomes and their comparison to matched normal DNAs. Several new and unexpected oncogenic mechanisms were suggested by the pattern of somatic mutation across the data set. These include the mutation of genes involved in protein translation (seen in nearly half of the patients), genes involved in histone methylation, and genes involved in blood coagulation. In addition, a broader than anticipated role of NF-kappaB signalling was indicated by mutations in 11 members of the NF-kappaB pathway. Of potential immediate clinical relevance, activating mutations of the kinase BRAF were observed in 4% of patients, suggesting the evaluation of BRAF inhibitors in multiple myeloma clinical trials. These results indicate that cancer genome sequencing of large collections of samples will yield new insights into cancer not anticipated by existing knowledge.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3560292/" 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/PMC3560292/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chapman, Michael A -- Lawrence, Michael S -- Keats, Jonathan J -- Cibulskis, Kristian -- Sougnez, Carrie -- Schinzel, Anna C -- Harview, Christina L -- Brunet, Jean-Philippe -- Ahmann, Gregory J -- Adli, Mazhar -- Anderson, Kenneth C -- Ardlie, Kristin G -- Auclair, Daniel -- Baker, Angela -- Bergsagel, P Leif -- Bernstein, Bradley E -- Drier, Yotam -- Fonseca, Rafael -- Gabriel, Stacey B -- Hofmeister, Craig C -- Jagannath, Sundar -- Jakubowiak, Andrzej J -- Krishnan, Amrita -- Levy, Joan -- Liefeld, Ted -- Lonial, Sagar -- Mahan, Scott -- Mfuko, Bunmi -- Monti, Stefano -- Perkins, Louise M -- Onofrio, Robb -- Pugh, Trevor J -- Rajkumar, S Vincent -- Ramos, Alex H -- Siegel, David S -- Sivachenko, Andrey -- Stewart, A Keith -- Trudel, Suzanne -- Vij, Ravi -- Voet, Douglas -- Winckler, Wendy -- Zimmerman, Todd -- Carpten, John -- Trent, Jeff -- Hahn, William C -- Garraway, Levi A -- Meyerson, Matthew -- Lander, Eric S -- Getz, Gad -- Golub, Todd R -- K12 CA133250/CA/NCI NIH HHS/ -- R01 AG020686/AG/NIA NIH HHS/ -- R01 AG020686-07/AG/NIA NIH HHS/ -- R01 CA133115/CA/NCI NIH HHS/ -- R01 CA133115-04/CA/NCI NIH HHS/ -- R01 CA133966/CA/NCI NIH HHS/ -- R01 CA133966-03/CA/NCI NIH HHS/ -- England -- Nature. 2011 Mar 24;471(7339):467-72. doi: 10.1038/nature09837.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Eli and Edythe L.

Description: Antigen-presenting molecules, encoded by the major histocompatibility complex (MHC) and CD1 family, bind peptide- and lipid-based antigens, respectively, for recognition by T cells. Mucosal-associated invariant T (MAIT) cells are an abundant population of innate-like T cells in humans that are activated by an antigen(s) bound to the MHC class I-like molecule MR1. Although the identity of MR1-restricted antigen(s) is unknown, it is present in numerous bacteria and yeast. Here we show that the structure and chemistry within the antigen-binding cleft of MR1 is distinct from the MHC and CD1 families. MR1 is ideally suited to bind ligands originating from vitamin metabolites. The structure of MR1 in complex with 6-formyl pterin, a folic acid (vitamin B9) metabolite, shows the pterin ring sequestered within MR1. Furthermore, we characterize related MR1-restricted vitamin derivatives, originating from the bacterial riboflavin (vitamin B2) biosynthetic pathway, which specifically and potently activate MAIT cells. Accordingly, we show that metabolites of vitamin B represent a class of antigen that are presented by MR1 for MAIT-cell immunosurveillance. As many vitamin biosynthetic pathways are unique to bacteria and yeast, our data suggest that MAIT cells use these metabolites to detect microbial infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kjer-Nielsen, Lars -- Patel, Onisha -- Corbett, Alexandra J -- Le Nours, Jerome -- Meehan, Bronwyn -- Liu, Ligong -- Bhati, Mugdha -- Chen, Zhenjun -- Kostenko, Lyudmila -- Reantragoon, Rangsima -- Williamson, Nicholas A -- Purcell, Anthony W -- Dudek, Nadine L -- McConville, Malcolm J -- O'Hair, Richard A J -- Khairallah, George N -- Godfrey, Dale I -- Fairlie, David P -- Rossjohn, Jamie -- McCluskey, James -- England -- Nature. 2012 Nov 29;491(7426):717-23. doi: 10.1038/nature11605.
