    Publication Date: 2008-10-25
    Description: Determining the genetic basis of cancer requires comprehensive analyses of large collections of histopathologically well-classified primary tumours. Here we report the results of a collaborative study to discover somatic mutations in 188 human lung adenocarcinomas. DNA sequencing of 623 genes with known or potential relationships to cancer revealed more than 1,000 somatic mutations across the samples. Our analysis identified 26 genes that are mutated at significantly high frequencies and thus are probably involved in carcinogenesis. The frequently mutated genes include tyrosine kinases, among them the EGFR homologue ERBB4; multiple ephrin receptor genes, notably EPHA3; vascular endothelial growth factor receptor KDR; and NTRK genes. These data provide evidence of somatic mutations in primary lung adenocarcinoma for several tumour suppressor genes involved in other cancers--including NF1, APC, RB1 and ATM--and for sequence changes in PTPRD as well as the frequently deleted gene LRP1B. The observed mutational profiles correlate with clinical features, smoking status and DNA repair defects. These results are reinforced by data integration including single nucleotide polymorphism array and gene expression array. Our findings shed further light on several important signalling pathways involved in lung adenocarcinoma, and suggest new molecular targets for treatment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2694412/" 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/PMC2694412/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ding, Li -- Getz, Gad -- Wheeler, David A -- Mardis, Elaine R -- McLellan, Michael D -- Cibulskis, Kristian -- Sougnez, Carrie -- Greulich, Heidi -- Muzny, Donna M -- Morgan, Margaret B -- Fulton, Lucinda -- Fulton, Robert S -- Zhang, Qunyuan -- Wendl, Michael C -- Lawrence, Michael S -- Larson, David E -- Chen, Ken -- Dooling, David J -- Sabo, Aniko -- Hawes, Alicia C -- Shen, Hua -- Jhangiani, Shalini N -- Lewis, Lora R -- Hall, Otis -- Zhu, Yiming -- Mathew, Tittu -- Ren, Yanru -- Yao, Jiqiang -- Scherer, Steven E -- Clerc, Kerstin -- Metcalf, Ginger A -- Ng, Brian -- Milosavljevic, Aleksandar -- Gonzalez-Garay, Manuel L -- Osborne, John R -- Meyer, Rick -- Shi, Xiaoqi -- Tang, Yuzhu -- Koboldt, Daniel C -- Lin, Ling -- Abbott, Rachel -- Miner, Tracie L -- Pohl, Craig -- Fewell, Ginger -- Haipek, Carrie -- Schmidt, Heather -- Dunford-Shore, Brian H -- Kraja, Aldi -- Crosby, Seth D -- Sawyer, Christopher S -- Vickery, Tammi -- Sander, Sacha -- Robinson, Jody -- Winckler, Wendy -- Baldwin, Jennifer -- Chirieac, Lucian R -- Dutt, Amit -- Fennell, Tim -- Hanna, Megan -- Johnson, Bruce E -- Onofrio, Robert C -- Thomas, Roman K -- Tonon, Giovanni -- Weir, Barbara A -- Zhao, Xiaojun -- Ziaugra, Liuda -- Zody, Michael C -- Giordano, Thomas -- Orringer, Mark B -- Roth, Jack A -- Spitz, Margaret R -- Wistuba, Ignacio I -- Ozenberger, Bradley -- Good, Peter J -- Chang, Andrew C -- Beer, David G -- Watson, Mark A -- Ladanyi, Marc -- Broderick, Stephen -- Yoshizawa, Akihiko -- Travis, William D -- Pao, William -- Province, Michael A -- Weinstock, George M -- Varmus, Harold E -- Gabriel, Stacey B -- Lander, Eric S -- Gibbs, Richard A -- Meyerson, Matthew -- Wilson, Richard K -- P50 CA070907/CA/NCI NIH HHS/ -- R01 CA154365/CA/NCI NIH HHS/ -- U19 CA084953/CA/NCI NIH HHS/ -- U19 CA084953-050003/CA/NCI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54 HG003067-04/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- England -- Nature. 2008 Oct 23;455(7216):1069-75. doi: 10.1038/nature07423.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Genome Center at Washington University, Department of Genetics, Washington University School of Medicine, St Louis, Missouri 63108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18948947" target="_blank"〉PubMed〈/a〉

    Genome analysis of the platypus reveals unique signatures of evolution (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-05-10
    Description: We present a draft genome sequence of the platypus, Ornithorhynchus anatinus. This monotreme exhibits a fascinating combination of reptilian and mammalian characters. For example, platypuses have a coat of fur adapted to an aquatic lifestyle; platypus females lactate, yet lay eggs; and males are equipped with venom similar to that of reptiles. Analysis of the first monotreme genome aligned these features with genetic innovations. We find that reptile and platypus venom proteins have been co-opted independently from the same gene families; milk protein genes are conserved despite platypuses laying eggs; and immune gene family expansions are directly related to platypus biology. Expansions of protein, non-protein-coding RNA and microRNA families, as well as repeat elements, are identified. Sequencing of this genome now provides a valuable resource for deep mammalian comparative analyses, as well as for monotreme biology and conservation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2803040/" 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/PMC2803040/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Wesley C -- Hillier, LaDeana W -- Marshall Graves, Jennifer A -- Birney, Ewan -- Ponting, Chris P -- Grutzner, Frank -- Belov, Katherine -- Miller, Webb -- Clarke, Laura -- Chinwalla, Asif T -- Yang, Shiaw-Pyng -- Heger, Andreas -- Locke, Devin P -- Miethke, Pat -- Waters, Paul D -- Veyrunes, Frederic -- Fulton, Lucinda -- Fulton, Bob -- Graves, Tina -- Wallis, John -- Puente, Xose S -- Lopez-Otin, Carlos -- Ordonez, Gonzalo R -- Eichler, Evan E -- Chen, Lin -- Cheng, Ze -- Deakin, Janine E -- Alsop, Amber -- Thompson, Katherine -- Kirby, Patrick -- Papenfuss, Anthony T -- Wakefield, Matthew J -- Olender, Tsviya -- Lancet, Doron -- Huttley, Gavin A -- Smit, Arian F A -- Pask, Andrew -- Temple-Smith, Peter -- Batzer, Mark A -- Walker, Jerilyn A -- Konkel, Miriam K -- Harris, Robert S -- Whittington, Camilla M -- Wong, Emily S W -- Gemmell, Neil J -- Buschiazzo, Emmanuel -- Vargas Jentzsch, Iris M -- Merkel, Angelika -- Schmitz, Juergen -- Zemann, Anja -- Churakov, Gennady -- Kriegs, Jan Ole -- Brosius, Juergen -- Murchison, Elizabeth P -- Sachidanandam, Ravi -- Smith, Carly -- Hannon, Gregory J -- Tsend-Ayush, Enkhjargal -- McMillan, Daniel -- Attenborough, Rosalind -- Rens, Willem -- Ferguson-Smith, Malcolm -- Lefevre, Christophe M -- Sharp, Julie A -- Nicholas, Kevin R -- Ray, David A -- Kube, Michael -- Reinhardt, Richard -- Pringle, Thomas H -- Taylor, James -- Jones, Russell C -- Nixon, Brett -- Dacheux, Jean-Louis -- Niwa, Hitoshi -- Sekita, Yoko -- Huang, Xiaoqiu -- Stark, Alexander -- Kheradpour, Pouya -- Kellis, Manolis -- Flicek, Paul -- Chen, Yuan -- Webber, Caleb -- Hardison, Ross -- Nelson, Joanne -- Hallsworth-Pepin, Kym -- Delehaunty, Kim -- Markovic, Chris -- Minx, Pat -- Feng, Yucheng -- Kremitzki, Colin -- Mitreva, Makedonka -- Glasscock, Jarret -- Wylie, Todd -- Wohldmann, Patricia -- Thiru, Prathapan -- Nhan, Michael N -- Pohl, Craig S -- Smith, Scott M -- Hou, Shunfeng -- Nefedov, Mikhail -- de Jong, Pieter J -- Renfree, Marilyn B -- Mardis, Elaine R -- Wilson, Richard K -- 062023/Wellcome Trust/United Kingdom -- HG002238/HG/NHGRI NIH HHS/ -- MC_U137761446/Medical Research Council/United Kingdom -- P01 CA013106/CA/NCI NIH HHS/ -- P01 CA013106-37/CA/NCI NIH HHS/ -- R01 GM59290/GM/NIGMS NIH HHS/ -- R01 HG002939/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG004037-02/HG/NHGRI NIH HHS/ -- R01HG02385/HG/NHGRI NIH HHS/ -- Medical Research Council/United Kingdom -- England -- Nature. 2008 May 8;453(7192):175-83. doi: 10.1038/nature06936.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genome Sequencing Center, Washington University School of Medicine, Campus Box 8501, 4444 Forest Park Avenue, St Louis, Missouri 63108, USA. wwarren@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18464734" target="_blank"〉PubMed〈/a〉

    Proteomic analysis of active multiple sclerosis lesions reveals therapeutic targets (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-02-19
    Description: Understanding the neuropathology of multiple sclerosis (MS) is essential for improved therapies. Therefore, identification of targets specific to pathological types of MS may have therapeutic benefits. Here we identify, by laser-capture microdissection and proteomics, proteins unique to three major types of MS lesions: acute plaque, chronic active plaque and chronic plaque. Comparative proteomic profiles identified tissue factor and protein C inhibitor within chronic active plaque samples, suggesting dysregulation of molecules associated with coagulation. In vivo administration of hirudin or recombinant activated protein C reduced disease severity in experimental autoimmune encephalomyelitis and suppressed Th1 and Th17 cytokines in astrocytes and immune cells. Administration of mutant forms of recombinant activated protein C showed that both its anticoagulant and its signalling functions were essential for optimal amelioration of experimental autoimmune encephalomyelitis. A proteomic approach illuminated potential therapeutic targets selective for specific pathological stages of MS and implicated participation of the coagulation cascade.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Han, May H -- Hwang, Sun-Il -- Roy, Dolly B -- Lundgren, Deborah H -- Price, Jordan V -- Ousman, Shalina S -- Fernald, Guy Haskin -- Gerlitz, Bruce -- Robinson, William H -- Baranzini, Sergio E -- Grinnell, Brian W -- Raine, Cedric S -- Sobel, Raymond A -- Han, David K -- Steinman, Lawrence -- T32 AI007290/AI/NIAID NIH HHS/ -- England -- Nature. 2008 Feb 28;451(7182):1076-81. doi: 10.1038/nature06559.

    Pluripotent stem cells induced from adult neural stem cells by reprogramming with two factors (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-07-03
    Description: Reprogramming of somatic cells is a valuable tool to understand the mechanisms of regaining pluripotency and further opens up the possibility of generating patient-specific pluripotent stem cells. Reprogramming of mouse and human somatic cells into pluripotent stem cells, designated as induced pluripotent stem (iPS) cells, has been possible with the expression of the transcription factor quartet Oct4 (also known as Pou5f1), Sox2, c-Myc and Klf4 (refs 1-11). Considering that ectopic expression of c-Myc causes tumorigenicity in offspring and that retroviruses themselves can cause insertional mutagenesis, the generation of iPS cells with a minimal number of factors may hasten the clinical application of this approach. Here we show that adult mouse neural stem cells express higher endogenous levels of Sox2 and c-Myc than embryonic stem cells, and that exogenous Oct4 together with either Klf4 or c-Myc is sufficient to generate iPS cells from neural stem cells. These two-factor iPS cells are similar to embryonic stem cells at the molecular level, contribute to development of the germ line, and form chimaeras. We propose that, in inducing pluripotency, the number of reprogramming factors can be reduced when using somatic cells that endogenously express appropriate levels of complementing factors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Jeong Beom -- Zaehres, Holm -- Wu, Guangming -- Gentile, Luca -- Ko, Kinarm -- Sebastiano, Vittorio -- Arauzo-Bravo, Marcos J -- Ruau, David -- Han, Dong Wook -- Zenke, Martin -- Scholer, Hans R -- England -- Nature. 2008 Jul 31;454(7204):646-50. doi: 10.1038/nature07061.

    A paracrine requirement for hedgehog signalling in cancer (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-08-30
    Description: Ligand-dependent activation of the hedgehog (Hh) signalling pathway has been associated with tumorigenesis in a number of human tissues. Here we show that, although previous reports have described a cell-autonomous role for Hh signalling in these tumours, Hh ligands fail to activate signalling in tumour epithelial cells. In contrast, our data support ligand-dependent activation of the Hh pathway in the stromal microenvironment. Specific inhibition of Hh signalling using small molecule inhibitors, a neutralizing anti-Hh antibody or genetic deletion of smoothened (Smo) in the mouse stroma results in growth inhibition in xenograft tumour models. Taken together, these studies demonstrate a paracrine requirement for Hh ligand signalling in the tumorigenesis of Hh-expressing cancers and have important implications for the development of Hh pathway antagonists in cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yauch, Robert L -- Gould, Stephen E -- Scales, Suzie J -- Tang, Tracy -- Tian, Hua -- Ahn, Christina P -- Marshall, Derek -- Fu, Ling -- Januario, Thomas -- Kallop, Dara -- Nannini-Pepe, Michelle -- Kotkow, Karen -- Marsters, James C -- Rubin, Lee L -- de Sauvage, Frederic J -- England -- Nature. 2008 Sep 18;455(7211):406-10. doi: 10.1038/nature07275.

    Sequencing the nuclear genome of the extinct woolly mammoth (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-11-21
    Description: In 1994, two independent groups extracted DNA from several Pleistocene epoch mammoths and noted differences among individual specimens. Subsequently, DNA sequences have been published for a number of extinct species. However, such ancient DNA is often fragmented and damaged, and studies to date have typically focused on short mitochondrial sequences, never yielding more than a fraction of a per cent of any nuclear genome. Here we describe 4.17 billion bases (Gb) of sequence from several mammoth specimens, 3.3 billion (80%) of which are from the woolly mammoth (Mammuthus primigenius) genome and thus comprise an extensive set of genome-wide sequence from an extinct species. Our data support earlier reports that elephantid genomes exceed 4 Gb. The estimated divergence rate between mammoth and African elephant is half of that between human and chimpanzee. The observed number of nucleotide differences between two particular mammoths was approximately one-eighth of that between one of them and the African elephant, corresponding to a separation between the mammoths of 1.5-2.0 Myr. The estimated probability that orthologous elephant and mammoth amino acids differ is 0.002, corresponding to about one residue per protein. Differences were discovered between mammoth and African elephant in amino-acid positions that are otherwise invariant over several billion years of combined mammalian evolution. This study shows that nuclear genome sequencing of extinct species can reveal population differences not evident from the fossil record, and perhaps even discover genetic factors that affect extinction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, Webb -- Drautz, Daniela I -- Ratan, Aakrosh -- Pusey, Barbara -- Qi, Ji -- Lesk, Arthur M -- Tomsho, Lynn P -- Packard, Michael D -- Zhao, Fangqing -- Sher, Andrei -- Tikhonov, Alexei -- Raney, Brian -- Patterson, Nick -- Lindblad-Toh, Kerstin -- Lander, Eric S -- Knight, James R -- Irzyk, Gerard P -- Fredrikson, Karin M -- Harkins, Timothy T -- Sheridan, Sharon -- Pringle, Tom -- Schuster, Stephan C -- HG002238/HG/NHGRI NIH HHS/ -- England -- Nature. 2008 Nov 20;456(7220):387-90. doi: 10.1038/nature07446.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Pennsylvania State University, Center for Comparative Genomics and Bioinformatics, 310 Wartik Building, University Park, Pennsylvania 16802, USA. webb@bx.psu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19020620" target="_blank"〉PubMed〈/a〉

    Impaired T(H)17 cell differentiation in subjects with autosomal dominant hyper-IgE syndrome (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-03-14
    Description: The autosomal dominant hyper-IgE syndrome (HIES, 'Job's syndrome') is characterized by recurrent and often severe pulmonary infections, pneumatoceles, eczema, staphylococcal abscesses, mucocutaneous candidiasis, and abnormalities of bone and connective tissue. Mutations presumed to underlie HIES have recently been identified in stat3, the gene encoding STAT3 (signal transducer and activator of transcription 3) (refs 3, 4). Although impaired production of interferon-gamma and tumour-necrosis factor by T cells, diminished memory T-cell populations, decreased delayed-type-hypersensitivity responses and decreased in vitro lymphoproliferation in response to specific antigens have variably been described, specific immunological abnormalities that can explain the unique susceptibility to particular infections seen in HIES have not yet been defined. Here we show that interleukin (IL)-17 production by T cells is absent in HIES individuals. We observed that ex vivo T cells from subjects with HIES failed to produce IL-17, but not IL-2, tumour-necrosis factor or interferon-gamma, on mitogenic stimulation with staphylococcal enterotoxin B or on antigenic stimulation with Candida albicans or streptokinase. Purified naive T cells were unable to differentiate into IL-17-producing (T(H)17) T helper cells in vitro and had lower expression of retinoid-related orphan receptor (ROR)-gammat, which is consistent with a crucial role for STAT3 signalling in the generation of T(H)17 cells. T(H)17 cells have emerged as an important subset of helper T cells that are believed to be critical in the clearance of fungal and extracellular bacterial infections. Thus, our data suggest that the inability to produce T(H)17 cells is a mechanism underlying the susceptibility to the recurrent infections commonly seen in HIES.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2864108/" 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/PMC2864108/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Milner, Joshua D -- Brenchley, Jason M -- Laurence, Arian -- Freeman, Alexandra F -- Hill, Brenna J -- Elias, Kevin M -- Kanno, Yuka -- Spalding, Christine -- Elloumi, Houda Z -- Paulson, Michelle L -- Davis, Joie -- Hsu, Amy -- Asher, Ava I -- O'Shea, John -- Holland, Steven M -- Paul, William E -- Douek, Daniel C -- Z99 AI999999/Intramural NIH HHS/ -- England -- Nature. 2008 Apr 10;452(7188):773-6. doi: 10.1038/nature06764.

    A variant associated with nicotine dependence, lung cancer and peripheral arterial disease (2008)

    Description: Smoking is a leading cause of preventable death, causing about 5 million premature deaths worldwide each year. Evidence for genetic influence on smoking behaviour and nicotine dependence (ND) has prompted a search for susceptibility genes. Furthermore, assessing the impact of sequence variants on smoking-related diseases is important to public health. Smoking is the major risk factor for lung cancer (LC) and is one of the main risk factors for peripheral arterial disease (PAD). Here we identify a common variant in the nicotinic acetylcholine receptor gene cluster on chromosome 15q24 with an effect on smoking quantity, ND and the risk of two smoking-related diseases in populations of European descent. The variant has an effect on the number of cigarettes smoked per day in our sample of smokers. The same variant was associated with ND in a previous genome-wide association study that used low-quantity smokers as controls, and with a similar approach we observe a highly significant association with ND. A comparison of cases of LC and PAD with population controls each showed that the variant confers risk of LC and PAD. The findings provide a case study of a gene-environment interaction, highlighting the role of nicotine addiction in the pathology of other serious diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4539558/" 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/PMC4539558/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thorgeirsson, Thorgeir E -- Geller, Frank -- Sulem, Patrick -- Rafnar, Thorunn -- Wiste, Anna -- Magnusson, Kristinn P -- Manolescu, Andrei -- Thorleifsson, Gudmar -- Stefansson, Hreinn -- Ingason, Andres -- Stacey, Simon N -- Bergthorsson, Jon T -- Thorlacius, Steinunn -- Gudmundsson, Julius -- Jonsson, Thorlakur -- Jakobsdottir, Margret -- Saemundsdottir, Jona -- Olafsdottir, Olof -- Gudmundsson, Larus J -- Bjornsdottir, Gyda -- Kristjansson, Kristleifur -- Skuladottir, Halla -- Isaksson, Helgi J -- Gudbjartsson, Tomas -- Jones, Gregory T -- Mueller, Thomas -- Gottsater, Anders -- Flex, Andrea -- Aben, Katja K H -- de Vegt, Femmie -- Mulders, Peter F A -- Isla, Dolores -- Vidal, Maria J -- Asin, Laura -- Saez, Berta -- Murillo, Laura -- Blondal, Thorsteinn -- Kolbeinsson, Halldor -- Stefansson, Jon G -- Hansdottir, Ingunn -- Runarsdottir, Valgerdur -- Pola, Roberto -- Lindblad, Bengt -- van Rij, Andre M -- Dieplinger, Benjamin -- Haltmayer, Meinhard -- Mayordomo, Jose I -- Kiemeney, Lambertus A -- Matthiasson, Stefan E -- Oskarsson, Hogni -- Tyrfingsson, Thorarinn -- Gudbjartsson, Daniel F -- Gulcher, Jeffrey R -- Jonsson, Steinn -- Thorsteinsdottir, Unnur -- Kong, Augustine -- Stefansson, Kari -- R01 DA017932/DA/NIDA NIH HHS/ -- England -- Nature. 2008 Apr 3;452(7187):638-42. doi: 10.1038/nature06846.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉deCODE Genetics, 101 Reykjavik, Iceland. thorgeir@decode.is〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18385739" target="_blank"〉PubMed〈/a〉

    Substrate-targeting gamma-secretase modulators (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-06-13
    Description: Selective lowering of Abeta42 levels (the 42-residue isoform of the amyloid-beta peptide) with small-molecule gamma-secretase modulators (GSMs), such as some non-steroidal anti-inflammatory drugs, is a promising therapeutic approach for Alzheimer's disease. To identify the target of these agents we developed biotinylated photoactivatable GSMs. GSM photoprobes did not label the core proteins of the gamma-secretase complex, but instead labelled the beta-amyloid precursor protein (APP), APP carboxy-terminal fragments and amyloid-beta peptide in human neuroglioma H4 cells. Substrate labelling was competed by other GSMs, and labelling of an APP gamma-secretase substrate was more efficient than a Notch substrate. GSM interaction was localized to residues 28-36 of amyloid-beta, a region critical for aggregation. We also demonstrate that compounds known to interact with this region of amyloid-beta act as GSMs, and some GSMs alter the production of cell-derived amyloid-beta oligomers. Furthermore, mutation of the GSM binding site in the APP alters the sensitivity of the substrate to GSMs. These findings indicate that substrate targeting by GSMs mechanistically links two therapeutic actions: alteration in Abeta42 production and inhibition of amyloid-beta aggregation, which may synergistically reduce amyloid-beta deposition in Alzheimer's disease. These data also demonstrate the existence and feasibility of 'substrate targeting' by small-molecule effectors of proteolytic enzymes, which if generally applicable may significantly broaden the current notion of 'druggable' targets.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2678541/" 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/PMC2678541/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kukar, Thomas L -- Ladd, Thomas B -- Bann, Maralyssa A -- Fraering, Patrick C -- Narlawar, Rajeshwar -- Maharvi, Ghulam M -- Healy, Brent -- Chapman, Robert -- Welzel, Alfred T -- Price, Robert W -- Moore, Brenda -- Rangachari, Vijayaraghavan -- Cusack, Bernadette -- Eriksen, Jason -- Jansen-West, Karen -- Verbeeck, Christophe -- Yager, Debra -- Eckman, Christopher -- Ye, Wenjuan -- Sagi, Sarah -- Cottrell, Barbara A -- Torpey, Justin -- Rosenberry, Terrone L -- Fauq, Abdul -- Wolfe, Michael S -- Schmidt, Boris -- Walsh, Dominic M -- Koo, Edward H -- Golde, Todd E -- P01 AG020206/AG/NIA NIH HHS/ -- P01 AG020206-010002/AG/NIA NIH HHS/ -- R01 AG017574/AG/NIA NIH HHS/ -- R01 AG017574-08/AG/NIA NIH HHS/ -- R01 AG017574-09/AG/NIA NIH HHS/ -- R01 NS041355/NS/NINDS NIH HHS/ -- R01 NS041355-06A2/NS/NINDS NIH HHS/ -- R01 NS041355-07/NS/NINDS NIH HHS/ -- England -- Nature. 2008 Jun 12;453(7197):925-9. doi: 10.1038/nature07055.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Mayo Clinic, Mayo Clinic College of Medicine, 4500 San Pablo Road, Jacksonville, Florida 32224, USA. kukar.thomas@mayo.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18548070" target="_blank"〉PubMed〈/a〉
