    Deterministic direct reprogramming of somatic cells to pluripotency (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-09-21
    Description: Somatic cells can be inefficiently and stochastically reprogrammed into induced pluripotent stem (iPS) cells by exogenous expression of Oct4 (also called Pou5f1), Sox2, Klf4 and Myc (hereafter referred to as OSKM). The nature of the predominant rate-limiting barrier(s) preventing the majority of cells to successfully and synchronously reprogram remains to be defined. Here we show that depleting Mbd3, a core member of the Mbd3/NuRD (nucleosome remodelling and deacetylation) repressor complex, together with OSKM transduction and reprogramming in naive pluripotency promoting conditions, result in deterministic and synchronized iPS cell reprogramming (near 100% efficiency within seven days from mouse and human cells). Our findings uncover a dichotomous molecular function for the reprogramming factors, serving to reactivate endogenous pluripotency networks while simultaneously directly recruiting the Mbd3/NuRD repressor complex that potently restrains the reactivation of OSKM downstream target genes. Subsequently, the latter interactions, which are largely depleted during early pre-implantation development in vivo, lead to a stochastic and protracted reprogramming trajectory towards pluripotency in vitro. The deterministic reprogramming approach devised here offers a novel platform for the dissection of molecular dynamics leading to establishing pluripotency at unprecedented flexibility and resolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rais, Yoach -- Zviran, Asaf -- Geula, Shay -- Gafni, Ohad -- Chomsky, Elad -- Viukov, Sergey -- Mansour, Abed AlFatah -- Caspi, Inbal -- Krupalnik, Vladislav -- Zerbib, Mirie -- Maza, Itay -- Mor, Nofar -- Baran, Dror -- Weinberger, Leehee -- Jaitin, Diego A -- Lara-Astiaso, David -- Blecher-Gonen, Ronnie -- Shipony, Zohar -- Mukamel, Zohar -- Hagai, Tzachi -- Gilad, Shlomit -- Amann-Zalcenstein, Daniela -- Tanay, Amos -- Amit, Ido -- Novershtern, Noa -- Hanna, Jacob H -- England -- Nature. 2013 Oct 3;502(7469):65-70. doi: 10.1038/nature12587.

    Antidiabetic effects of glucokinase regulatory protein small-molecule disruptors (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-11-15
    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.

    Targeting Plasmodium PI(4)K to eliminate malaria (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-11-29
    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.

    Limited airborne transmission of H7N9 influenza A virus between ferrets (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-08-09
    Description: Wild waterfowl form the main reservoir of influenza A viruses, from which transmission occurs directly or indirectly to various secondary hosts, including humans. Direct avian-to-human transmission has been observed for viruses of subtypes A(H5N1), A(H7N2), A(H7N3), A(H7N7), A(H9N2) and A(H10N7) upon human exposure to poultry, but a lack of sustained human-to-human transmission has prevented these viruses from causing new pandemics. Recently, avian A(H7N9) viruses were transmitted to humans, causing severe respiratory disease and deaths in China. Because transmission via respiratory droplets and aerosols (hereafter referred to as airborne transmission) is the main route for efficient transmission between humans, it is important to gain an insight into airborne transmission of the A(H7N9) virus. Here we show that although the A/Anhui/1/2013 A(H7N9) virus harbours determinants associated with human adaptation and transmissibility between mammals, its airborne transmissibility in ferrets is limited, and it is intermediate between that of typical human and avian influenza viruses. Multiple A(H7N9) virus genetic variants were transmitted. Upon ferret passage, variants with higher avian receptor binding, higher pH of fusion, and lower thermostability were selected, potentially resulting in reduced transmissibility. This A(H7N9) virus outbreak highlights the need for increased understanding of the determinants of efficient airborne transmission of avian influenza viruses between mammals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3819191/" 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/PMC3819191/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Richard, Mathilde -- Schrauwen, Eefje J A -- de Graaf, Miranda -- Bestebroer, Theo M -- Spronken, Monique I J -- van Boheemen, Sander -- de Meulder, Dennis -- Lexmond, Pascal -- Linster, Martin -- Herfst, Sander -- Smith, Derek J -- van den Brand, Judith M -- Burke, David F -- Kuiken, Thijs -- Rimmelzwaan, Guus F -- Osterhaus, Albert D M E -- Fouchier, Ron A M -- HHSN266200700010C/AI/NIAID NIH HHS/ -- HHSN266200700010C/PHS HHS/ -- England -- Nature. 2013 Sep 26;501(7468):560-3. doi: 10.1038/nature12476.

    Mutations in prion-like domains in hnRNPA2B1 and hnRNPA1 cause multisystem proteinopathy and ALS (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-03-05
    Description: Algorithms designed to identify canonical yeast prions predict that around 250 human proteins, including several RNA-binding proteins associated with neurodegenerative disease, harbour a distinctive prion-like domain (PrLD) enriched in uncharged polar amino acids and glycine. PrLDs in RNA-binding proteins are essential for the assembly of ribonucleoprotein granules. However, the interplay between human PrLD function and disease is not understood. Here we define pathogenic mutations in PrLDs of heterogeneous nuclear ribonucleoproteins (hnRNPs) A2B1 and A1 in families with inherited degeneration affecting muscle, brain, motor neuron and bone, and in one case of familial amyotrophic lateral sclerosis. Wild-type hnRNPA2 (the most abundant isoform of hnRNPA2B1) and hnRNPA1 show an intrinsic tendency to assemble into self-seeding fibrils, which is exacerbated by the disease mutations. Indeed, the pathogenic mutations strengthen a 'steric zipper' motif in the PrLD, which accelerates the formation of self-seeding fibrils that cross-seed polymerization of wild-type hnRNP. Notably, the disease mutations promote excess incorporation of hnRNPA2 and hnRNPA1 into stress granules and drive the formation of cytoplasmic inclusions in animal models that recapitulate the human pathology. Thus, dysregulated polymerization caused by a potent mutant steric zipper motif in a PrLD can initiate degenerative disease. Related proteins with PrLDs should therefore be considered candidates for initiating and perhaps propagating proteinopathies of muscle, brain, motor neuron and bone.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3756911/" 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/PMC3756911/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Hong Joo -- Kim, Nam Chul -- Wang, Yong-Dong -- Scarborough, Emily A -- Moore, Jennifer -- Diaz, Zamia -- MacLea, Kyle S -- Freibaum, Brian -- Li, Songqing -- Molliex, Amandine -- Kanagaraj, Anderson P -- Carter, Robert -- Boylan, Kevin B -- Wojtas, Aleksandra M -- Rademakers, Rosa -- Pinkus, Jack L -- Greenberg, Steven A -- Trojanowski, John Q -- Traynor, Bryan J -- Smith, Bradley N -- Topp, Simon -- Gkazi, Athina-Soragia -- Miller, Jack -- Shaw, Christopher E -- Kottlors, Michael -- Kirschner, Janbernd -- Pestronk, Alan -- Li, Yun R -- Ford, Alice Flynn -- Gitler, Aaron D -- Benatar, Michael -- King, Oliver D -- Kimonis, Virginia E -- Ross, Eric D -- Weihl, Conrad C -- Shorter, James -- Taylor, J Paul -- 089701/Wellcome Trust/United Kingdom -- AG031867/AG/NIA NIH HHS/ -- AG032953/AG/NIA NIH HHS/ -- DP2OD002177/OD/NIH HHS/ -- G0900688/Medical Research Council/United Kingdom -- K02 AG042095/AG/NIA NIH HHS/ -- MC_G1000733/Medical Research Council/United Kingdom -- NS053825/NS/NINDS NIH HHS/ -- NS067354/NS/NINDS NIH HHS/ -- P01 AG032953/AG/NIA NIH HHS/ -- R01 AG031867/AG/NIA NIH HHS/ -- R01 NS053825/NS/NINDS NIH HHS/ -- England -- Nature. 2013 Mar 28;495(7442):467-73. doi: 10.1038/nature11922.

    Rational HIV immunogen design to target specific germline B cell receptors (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-03-30
    Description: Vaccine development to induce broadly neutralizing antibodies (bNAbs) against HIV-1 is a global health priority. Potent VRC01-class bNAbs against the CD4 binding site of HIV gp120 have been isolated from HIV-1-infected individuals; however, such bNAbs have not been induced by vaccination. Wild-type gp120 proteins lack detectable affinity for predicted germline precursors of VRC01-class bNAbs, making them poor immunogens to prime a VRC01-class response. We employed computation-guided, in vitro screening to engineer a germline-targeting gp120 outer domain immunogen that binds to multiple VRC01-class bNAbs and germline precursors, and elucidated germline binding crystallographically. When multimerized on nanoparticles, this immunogen (eOD-GT6) activates germline and mature VRC01-class B cells. Thus, eOD-GT6 nanoparticles have promise as a vaccine prime. In principle, germline-targeting strategies could be applied to other epitopes and pathogens.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3689846/" 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/PMC3689846/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jardine, Joseph -- Julien, Jean-Philippe -- Menis, Sergey -- Ota, Takayuki -- Kalyuzhniy, Oleksandr -- McGuire, Andrew -- Sok, Devin -- Huang, Po-Ssu -- MacPherson, Skye -- Jones, Meaghan -- Nieusma, Travis -- Mathison, John -- Baker, David -- Ward, Andrew B -- Burton, Dennis R -- Stamatatos, Leonidas -- Nemazee, David -- Wilson, Ian A -- Schief, William R -- 5T32AI007606-10/AI/NIAID NIH HHS/ -- AI081625/AI/NIAID NIH HHS/ -- AI33292/AI/NIAID NIH HHS/ -- AI84817/AI/NIAID NIH HHS/ -- P01 AI094419/AI/NIAID NIH HHS/ -- P30 AI027767-24/AI/NIAID NIH HHS/ -- P41RR001209/RR/NCRR NIH HHS/ -- R01 AI033292/AI/NIAID NIH HHS/ -- R01 AI073148/AI/NIAID NIH HHS/ -- R01 AI081625/AI/NIAID NIH HHS/ -- R01 AI084817/AI/NIAID NIH HHS/ -- R37 AI033292/AI/NIAID NIH HHS/ -- T32 CA080416/CA/NCI NIH HHS/ -- T32CA080416/CA/NCI NIH HHS/ -- UM1 AI100663/AI/NIAID NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2013 May 10;340(6133):711-6. doi: 10.1126/science.1234150.
