    Genomic analyses identify molecular subtypes of pancreatic cancer (2016)
    Nature Publishing Group (NPG)

    Publication Date: 2016-02-26
    Description: Integrated genomic analysis of 456 pancreatic ductal adenocarcinomas identified 32 recurrently mutated genes that aggregate into 10 pathways: KRAS, TGF-beta, WNT, NOTCH, ROBO/SLIT signalling, G1/S transition, SWI-SNF, chromatin modification, DNA repair and RNA processing. Expression analysis defined 4 subtypes: (1) squamous; (2) pancreatic progenitor; (3) immunogenic; and (4) aberrantly differentiated endocrine exocrine (ADEX) that correlate with histopathological characteristics. Squamous tumours are enriched for TP53 and KDM6A mutations, upregulation of the TP63N transcriptional network, hypermethylation of pancreatic endodermal cell-fate determining genes and have a poor prognosis. Pancreatic progenitor tumours preferentially express genes involved in early pancreatic development (FOXA2/3, PDX1 and MNX1). ADEX tumours displayed upregulation of genes that regulate networks involved in KRAS activation, exocrine (NR5A2 and RBPJL), and endocrine differentiation (NEUROD1 and NKX2-2). Immunogenic tumours contained upregulated immune networks including pathways involved in acquired immune suppression. These data infer differences in the molecular evolution of pancreatic cancer subtypes and identify opportunities for therapeutic development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bailey, Peter -- Chang, David K -- Nones, Katia -- Johns, Amber L -- Patch, Ann-Marie -- Gingras, Marie-Claude -- Miller, David K -- Christ, Angelika N -- Bruxner, Tim J C -- Quinn, Michael C -- Nourse, Craig -- Murtaugh, L Charles -- Harliwong, Ivon -- Idrisoglu, Senel -- Manning, Suzanne -- Nourbakhsh, Ehsan -- Wani, Shivangi -- Fink, Lynn -- Holmes, Oliver -- Chin, Venessa -- Anderson, Matthew J -- Kazakoff, Stephen -- Leonard, Conrad -- Newell, Felicity -- Waddell, Nick -- Wood, Scott -- Xu, Qinying -- Wilson, Peter J -- Cloonan, Nicole -- Kassahn, Karin S -- Taylor, Darrin -- Quek, Kelly -- Robertson, Alan -- Pantano, Lorena -- Mincarelli, Laura -- Sanchez, Luis N -- Evers, Lisa -- Wu, Jianmin -- Pinese, Mark -- Cowley, Mark J -- Jones, Marc D -- Colvin, Emily K -- Nagrial, Adnan M -- Humphrey, Emily S -- Chantrill, Lorraine A -- Mawson, Amanda -- Humphris, Jeremy -- Chou, Angela -- Pajic, Marina -- Scarlett, Christopher J -- Pinho, Andreia V -- Giry-Laterriere, Marc -- Rooman, Ilse -- Samra, Jaswinder S -- Kench, James G -- Lovell, Jessica A -- Merrett, Neil D -- Toon, Christopher W -- Epari, Krishna -- Nguyen, Nam Q -- Barbour, Andrew -- Zeps, Nikolajs -- Moran-Jones, Kim -- Jamieson, Nigel B -- Graham, Janet S -- Duthie, Fraser -- Oien, Karin -- Hair, Jane -- Grutzmann, Robert -- Maitra, Anirban -- Iacobuzio-Donahue, Christine A -- Wolfgang, Christopher L -- Morgan, Richard A -- Lawlor, Rita T -- Corbo, Vincenzo -- Bassi, Claudio -- Rusev, Borislav -- Capelli, Paola -- Salvia, Roberto -- Tortora, Giampaolo -- Mukhopadhyay, Debabrata -- Petersen, Gloria M -- Australian Pancreatic Cancer Genome Initiative -- Munzy, Donna M -- Fisher, William E -- Karim, Saadia A -- Eshleman, James R -- Hruban, Ralph H -- Pilarsky, Christian -- Morton, Jennifer P -- Sansom, Owen J -- Scarpa, Aldo -- Musgrove, Elizabeth A -- Bailey, Ulla-Maja Hagbo -- Hofmann, Oliver -- Sutherland, Robert L -- Wheeler, David A -- Gill, Anthony J -- Gibbs, Richard A -- Pearson, John V -- Waddell, Nicola -- Biankin, Andrew V -- Grimmond, Sean M -- 103721/Z/14/Z/Wellcome Trust/United Kingdom -- A12481/Cancer Research UK/United Kingdom -- A18076/Cancer Research UK/United Kingdom -- C29717/A17263/Cancer Research UK/United Kingdom -- England -- Nature. 2016 Mar 3;531(7592):47-52. doi: 10.1038/nature16965.

    Biomass resilience of Neotropical secondary forests (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-02-04
    Description: Land-use change occurs nowhere more rapidly than in the tropics, where the imbalance between deforestation and forest regrowth has large consequences for the global carbon cycle. However, considerable uncertainty remains about the rate of biomass recovery in secondary forests, and how these rates are influenced by climate, landscape, and prior land use. Here we analyse aboveground biomass recovery during secondary succession in 45 forest sites and about 1,500 forest plots covering the major environmental gradients in the Neotropics. The studied secondary forests are highly productive and resilient. Aboveground biomass recovery after 20 years was on average 122 megagrams per hectare (Mg ha(-1)), corresponding to a net carbon uptake of 3.05 Mg C ha(-1) yr(-1), 11 times the uptake rate of old-growth forests. Aboveground biomass stocks took a median time of 66 years to recover to 90% of old-growth values. Aboveground biomass recovery after 20 years varied 11.3-fold (from 20 to 225 Mg ha(-1)) across sites, and this recovery increased with water availability (higher local rainfall and lower climatic water deficit). We present a biomass recovery map of Latin America, which illustrates geographical and climatic variation in carbon sequestration potential during forest regrowth. The map will support policies to minimize forest loss in areas where biomass resilience is naturally low (such as seasonally dry forest regions) and promote forest regeneration and restoration in humid tropical lowland areas with high biomass resilience.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Poorter, Lourens -- Bongers, Frans -- Aide, T Mitchell -- Almeyda Zambrano, Angelica M -- Balvanera, Patricia -- Becknell, Justin M -- Boukili, Vanessa -- Brancalion, Pedro H S -- Broadbent, Eben N -- Chazdon, Robin L -- Craven, Dylan -- de Almeida-Cortez, Jarcilene S -- Cabral, George A L -- de Jong, Ben H J -- Denslow, Julie S -- Dent, Daisy H -- DeWalt, Saara J -- Dupuy, Juan M -- Duran, Sandra M -- Espirito-Santo, Mario M -- Fandino, Maria C -- Cesar, Ricardo G -- Hall, Jefferson S -- Hernandez-Stefanoni, Jose Luis -- Jakovac, Catarina C -- Junqueira, Andre B -- Kennard, Deborah -- Letcher, Susan G -- Licona, Juan-Carlos -- Lohbeck, Madelon -- Marin-Spiotta, Erika -- Martinez-Ramos, Miguel -- Massoca, Paulo -- Meave, Jorge A -- Mesquita, Rita -- Mora, Francisco -- Munoz, Rodrigo -- Muscarella, Robert -- Nunes, Yule R F -- Ochoa-Gaona, Susana -- de Oliveira, Alexandre A -- Orihuela-Belmonte, Edith -- Pena-Claros, Marielos -- Perez-Garcia, Eduardo A -- Piotto, Daniel -- Powers, Jennifer S -- Rodriguez-Velazquez, Jorge -- Romero-Perez, I Eunice -- Ruiz, Jorge -- Saldarriaga, Juan G -- Sanchez-Azofeifa, Arturo -- Schwartz, Naomi B -- Steininger, Marc K -- Swenson, Nathan G -- Toledo, Marisol -- Uriarte, Maria -- van Breugel, Michiel -- van der Wal, Hans -- Veloso, Maria D M -- Vester, Hans F M -- Vicentini, Alberto -- Vieira, Ima C G -- Bentos, Tony Vizcarra -- Williamson, G Bruce -- Rozendaal, Danae M A -- England -- Nature. 2016 Feb 11;530(7589):211-4. doi: 10.1038/nature16512.

    Therapeutic efficacy of the small molecule GS-5734 against Ebola virus in rhesus monkeys (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-03-05
    Description: The most recent Ebola virus outbreak in West Africa, which was unprecedented in the number of cases and fatalities, geographic distribution, and number of nations affected, highlights the need for safe, effective, and readily available antiviral agents for treatment and prevention of acute Ebola virus (EBOV) disease (EVD) or sequelae. No antiviral therapeutics have yet received regulatory approval or demonstrated clinical efficacy. Here we report the discovery of a novel small molecule GS-5734, a monophosphoramidate prodrug of an adenosine analogue, with antiviral activity against EBOV. GS-5734 exhibits antiviral activity against multiple variants of EBOV and other filoviruses in cell-based assays. The pharmacologically active nucleoside triphosphate (NTP) is efficiently formed in multiple human cell types incubated with GS-5734 in vitro, and the NTP acts as an alternative substrate and RNA-chain terminator in primer-extension assays using a surrogate respiratory syncytial virus RNA polymerase. Intravenous administration of GS-5734 to nonhuman primates resulted in persistent NTP levels in peripheral blood mononuclear cells (half-life, 14 h) and distribution to sanctuary sites for viral replication including testes, eyes, and brain. In a rhesus monkey model of EVD, once-daily intravenous administration of 10 mg kg(-1) GS-5734 for 12 days resulted in profound suppression of EBOV replication and protected 100% of EBOV-infected animals against lethal disease, ameliorating clinical disease signs and pathophysiological markers, even when treatments were initiated three days after virus exposure when systemic viral RNA was detected in two out of six treated animals. These results show the first substantive post-exposure protection by a small-molecule antiviral compound against EBOV in nonhuman primates. The broad-spectrum antiviral activity of GS-5734 in vitro against other pathogenic RNA viruses, including filoviruses, arenaviruses, and coronaviruses, suggests the potential for wider medical use. GS-5734 is amenable to large-scale manufacturing, and clinical studies investigating the drug safety and pharmacokinetics are ongoing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Travis K -- Jordan, Robert -- Lo, Michael K -- Ray, Adrian S -- Mackman, Richard L -- Soloveva, Veronica -- Siegel, Dustin -- Perron, Michel -- Bannister, Roy -- Hui, Hon C -- Larson, Nate -- Strickley, Robert -- Wells, Jay -- Stuthman, Kelly S -- Van Tongeren, Sean A -- Garza, Nicole L -- Donnelly, Ginger -- Shurtleff, Amy C -- Retterer, Cary J -- Gharaibeh, Dima -- Zamani, Rouzbeh -- Kenny, Tara -- Eaton, Brett P -- Grimes, Elizabeth -- Welch, Lisa S -- Gomba, Laura -- Wilhelmsen, Catherine L -- Nichols, Donald K -- Nuss, Jonathan E -- Nagle, Elyse R -- Kugelman, Jeffrey R -- Palacios, Gustavo -- Doerffler, Edward -- Neville, Sean -- Carra, Ernest -- Clarke, Michael O -- Zhang, Lijun -- Lew, Willard -- Ross, Bruce -- Wang, Queenie -- Chun, Kwon -- Wolfe, Lydia -- Babusis, Darius -- Park, Yeojin -- Stray, Kirsten M -- Trancheva, Iva -- Feng, Joy Y -- Barauskas, Ona -- Xu, Yili -- Wong, Pamela -- Braun, Molly R -- Flint, Mike -- McMullan, Laura K -- Chen, Shan-Shan -- Fearns, Rachel -- Swaminathan, Swami -- Mayers, Douglas L -- Spiropoulou, Christina F -- Lee, William A -- Nichol, Stuart T -- Cihlar, Tomas -- Bavari, Sina -- R01 AI113321/AI/NIAID NIH HHS/ -- R01AI113321/AI/NIAID NIH HHS/ -- England -- Nature. 2016 Mar 17;531(7594):381-5. doi: 10.1038/nature17180.

    Real-time, portable genome sequencing for Ebola surveillance (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-02-04
    Description: The Ebola virus disease epidemic in West Africa is the largest on record, responsible for over 28,599 cases and more than 11,299 deaths. Genome sequencing in viral outbreaks is desirable to characterize the infectious agent and determine its evolutionary rate. Genome sequencing also allows the identification of signatures of host adaptation, identification and monitoring of diagnostic targets, and characterization of responses to vaccines and treatments. The Ebola virus (EBOV) genome substitution rate in the Makona strain has been estimated at between 0.87 x 10(-3) and 1.42 x 10(-3) mutations per site per year. This is equivalent to 16-27 mutations in each genome, meaning that sequences diverge rapidly enough to identify distinct sub-lineages during a prolonged epidemic. Genome sequencing provides a high-resolution view of pathogen evolution and is increasingly sought after for outbreak surveillance. Sequence data may be used to guide control measures, but only if the results are generated quickly enough to inform interventions. Genomic surveillance during the epidemic has been sporadic owing to a lack of local sequencing capacity coupled with practical difficulties transporting samples to remote sequencing facilities. To address this problem, here we devise a genomic surveillance system that utilizes a novel nanopore DNA sequencing instrument. In April 2015 this system was transported in standard airline luggage to Guinea and used for real-time genomic surveillance of the ongoing epidemic. We present sequence data and analysis of 142 EBOV samples collected during the period March to October 2015. We were able to generate results less than 24 h after receiving an Ebola-positive sample, with the sequencing process taking as little as 15-60 min. We show that real-time genomic surveillance is possible in resource-limited settings and can be established rapidly to monitor outbreaks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Quick, Joshua -- Loman, Nicholas J -- Duraffour, Sophie -- Simpson, Jared T -- Severi, Ettore -- Cowley, Lauren -- Bore, Joseph Akoi -- Koundouno, Raymond -- Dudas, Gytis -- Mikhail, Amy -- Ouedraogo, Nobila -- Afrough, Babak -- Bah, Amadou -- Baum, Jonathan H J -- Becker-Ziaja, Beate -- Boettcher, Jan Peter -- Cabeza-Cabrerizo, Mar -- Camino-Sanchez, Alvaro -- Carter, Lisa L -- Doerrbecker, Juliane -- Enkirch, Theresa -- Garcia-Dorival, Isabel -- Hetzelt, Nicole -- Hinzmann, Julia -- Holm, Tobias -- Kafetzopoulou, Liana Eleni -- Koropogui, Michel -- Kosgey, Abigael -- Kuisma, Eeva -- Logue, Christopher H -- Mazzarelli, Antonio -- Meisel, Sarah -- Mertens, Marc -- Michel, Janine -- Ngabo, Didier -- Nitzsche, Katja -- Pallasch, Elisa -- Patrono, Livia Victoria -- Portmann, Jasmine -- Repits, Johanna Gabriella -- Rickett, Natasha Y -- Sachse, Andreas -- Singethan, Katrin -- Vitoriano, Ines -- Yemanaberhan, Rahel L -- Zekeng, Elsa G -- Racine, Trina -- Bello, Alexander -- Sall, Amadou Alpha -- Faye, Ousmane -- Faye, Oumar -- Magassouba, N'Faly -- Williams, Cecelia V -- Amburgey, Victoria -- Winona, Linda -- Davis, Emily -- Gerlach, Jon -- Washington, Frank -- Monteil, Vanessa -- Jourdain, Marine -- Bererd, Marion -- Camara, Alimou -- Somlare, Hermann -- Camara, Abdoulaye -- Gerard, Marianne -- Bado, Guillaume -- Baillet, Bernard -- Delaune, Deborah -- Nebie, Koumpingnin Yacouba -- Diarra, Abdoulaye -- Savane, Yacouba -- Pallawo, Raymond Bernard -- Gutierrez, Giovanna Jaramillo -- Milhano, Natacha -- Roger, Isabelle -- Williams, Christopher J -- Yattara, Facinet -- Lewandowski, Kuiama -- Taylor, James -- Rachwal, Phillip -- Turner, Daniel J -- Pollakis, Georgios -- Hiscox, Julian A -- Matthews, David A -- O'Shea, Matthew K -- Johnston, Andrew McD -- Wilson, Duncan -- Hutley, Emma -- Smit, Erasmus -- Di Caro, Antonino -- Wolfel, Roman -- Stoecker, Kilian -- Fleischmann, Erna -- Gabriel, Martin -- Weller, Simon A -- Koivogui, Lamine -- Diallo, Boubacar -- Keita, Sakoba -- Rambaut, Andrew -- Formenty, Pierre -- Gunther, Stephan -- Carroll, Miles W -- Medical Research Council/United Kingdom -- England -- Nature. 2016 Feb 11;530(7589):228-32. doi: 10.1038/nature16996.

    Vast assembly of vocal marine mammals from diverse species on fish spawning ground (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-03-05
    Description: Observing marine mammal (MM) populations continuously in time and space over the immense ocean areas they inhabit is challenging but essential for gathering an unambiguous record of their distribution, as well as understanding their behaviour and interaction with prey species. Here we use passive ocean acoustic waveguide remote sensing (POAWRS) in an important North Atlantic feeding ground to instantaneously detect, localize and classify MM vocalizations from diverse species over an approximately 100,000 km(2) region. More than eight species of vocal MMs are found to spatially converge on fish spawning areas containing massive densely populated herring shoals at night-time and diffuse herring distributions during daytime. We find the vocal MMs divide the enormous fish prey field into species-specific foraging areas with varying degrees of spatial overlap, maintained for at least two weeks of the herring spawning period. The recorded vocalization rates are diel (24 h)-dependent for all MM species, with some significantly more vocal at night and others more vocal during the day. The four key baleen whale species of the region: fin, humpback, blue and minke have vocalization rate trends that are highly correlated to trends in fish shoaling density and to each other over the diel cycle. These results reveal the temporospatial dynamics of combined multi-species MM foraging activities in the vicinity of an extensive fish prey field that forms a massive ecological hotspot, and would be unattainable with conventional methodologies. Understanding MM behaviour and distributions is essential for management of marine ecosystems and for accessing anthropogenic impacts on these protected marine species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Delin -- Garcia, Heriberto -- Huang, Wei -- Tran, Duong D -- Jain, Ankita D -- Yi, Dong Hoon -- Gong, Zheng -- Jech, J Michael -- Godo, Olav Rune -- Makris, Nicholas C -- Ratilal, Purnima -- England -- Nature. 2016 Mar 17;531(7594):366-70. doi: 10.1038/nature16960.

    High-fat diet enhances stemness and tumorigenicity of intestinal progenitors (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-03-05
    Description: Little is known about how pro-obesity diets regulate tissue stem and progenitor cell function. Here we show that high-fat diet (HFD)-induced obesity augments the numbers and function of Lgr5(+) intestinal stem cells of the mammalian intestine. Mechanistically, a HFD induces a robust peroxisome proliferator-activated receptor delta (PPAR-delta) signature in intestinal stem cells and progenitor cells (non-intestinal stem cells), and pharmacological activation of PPAR-delta recapitulates the effects of a HFD on these cells. Like a HFD, ex vivo treatment of intestinal organoid cultures with fatty acid constituents of the HFD enhances the self-renewal potential of these organoid bodies in a PPAR-delta-dependent manner. Notably, HFD- and agonist-activated PPAR-delta signalling endow organoid-initiating capacity to progenitors, and enforced PPAR-delta signalling permits these progenitors to form in vivo tumours after loss of the tumour suppressor Apc. These findings highlight how diet-modulated PPAR-delta activation alters not only the function of intestinal stem and progenitor cells, but also their capacity to initiate tumours.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4846772/" 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/PMC4846772/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beyaz, Semir -- Mana, Miyeko D -- Roper, Jatin -- Kedrin, Dmitriy -- Saadatpour, Assieh -- Hong, Sue-Jean -- Bauer-Rowe, Khristian E -- Xifaras, Michael E -- Akkad, Adam -- Arias, Erika -- Pinello, Luca -- Katz, Yarden -- Shinagare, Shweta -- Abu-Remaileh, Monther -- Mihaylova, Maria M -- Lamming, Dudley W -- Dogum, Rizkullah -- Guo, Guoji -- Bell, George W -- Selig, Martin -- Nielsen, G Petur -- Gupta, Nitin -- Ferrone, Cristina R -- Deshpande, Vikram -- Yuan, Guo-Cheng -- Orkin, Stuart H -- Sabatini, David M -- Yilmaz, Omer H -- AI47389/AI/NIAID NIH HHS/ -- DK043351/DK/NIDDK NIH HHS/ -- K08 CA198002/CA/NCI NIH HHS/ -- K99 AG041765/AG/NIA NIH HHS/ -- K99 AG045144/AG/NIA NIH HHS/ -- P30 CA014051/CA/NCI NIH HHS/ -- P30-CA14051/CA/NCI NIH HHS/ -- R00 AG041765/AG/NIA NIH HHS/ -- R00 AG045144/AG/NIA NIH HHS/ -- R01 AI047389/AI/NIAID NIH HHS/ -- R01 CA103866/CA/NCI NIH HHS/ -- R01 CA129105/CA/NCI NIH HHS/ -- R37 AI047389/AI/NIAID NIH HHS/ -- T32DK007191/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2016 Mar 3;531(7592):53-8. doi: 10.1038/nature17173.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The David H.

    The necrosome promotes pancreatic oncogenesis via CXCL1 and Mincle-induced immune suppression (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-04-07
    Description: Neoplastic pancreatic epithelial cells are believed to die through caspase 8-dependent apoptotic cell death, and chemotherapy is thought to promote tumour apoptosis. Conversely, cancer cells often disrupt apoptosis to survive. Another type of programmed cell death is necroptosis (programmed necrosis), but its role in pancreatic ductal adenocarcinoma (PDA) is unclear. There are many potential inducers of necroptosis in PDA, including ligation of tumour necrosis factor receptor 1 (TNFR1), CD95, TNF-related apoptosis-inducing ligand (TRAIL) receptors, Toll-like receptors, reactive oxygen species, and chemotherapeutic drugs. Here we report that the principal components of the necrosome, receptor-interacting protein (RIP)1 and RIP3, are highly expressed in PDA and are further upregulated by the chemotherapy drug gemcitabine. Blockade of the necrosome in vitro promoted cancer cell proliferation and induced an aggressive oncogenic phenotype. By contrast, in vivo deletion of RIP3 or inhibition of RIP1 protected against oncogenic progression in mice and was associated with the development of a highly immunogenic myeloid and T cell infiltrate. The immune-suppressive tumour microenvironment associated with intact RIP1/RIP3 signalling depended in part on necroptosis-induced expression of the chemokine attractant CXCL1, and CXCL1 blockade protected against PDA. Moreover, cytoplasmic SAP130 (a subunit of the histone deacetylase complex) was expressed in PDA in a RIP1/RIP3-dependent manner, and Mincle--its cognate receptor--was upregulated in tumour-infiltrating myeloid cells. Ligation of Mincle by SAP130 promoted oncogenesis, whereas deletion of Mincle protected against oncogenesis and phenocopied the immunogenic reprogramming of the tumour microenvironment that was induced by RIP3 deletion. Cellular depletion suggested that whereas inhibitory macrophages promote tumorigenesis in PDA, they lose their immune-suppressive effects when RIP3 or Mincle is deleted. Accordingly, T cells, which are not protective against PDA progression in mice with intact RIP3 or Mincle signalling, are reprogrammed into indispensable mediators of anti-tumour immunity in the absence of RIP3 or Mincle. Our work describes parallel networks of necroptosis-induced CXCL1 and Mincle signalling that promote macrophage-induced adaptive immune suppression and thereby enable PDA progression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4833566/" 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/PMC4833566/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seifert, Lena -- Werba, Gregor -- Tiwari, Shaun -- Giao Ly, Nancy Ngoc -- Alothman, Sara -- Alqunaibit, Dalia -- Avanzi, Antonina -- Barilla, Rocky -- Daley, Donnele -- Greco, Stephanie H -- Torres-Hernandez, Alejandro -- Pergamo, Matthew -- Ochi, Atsuo -- Zambirinis, Constantinos P -- Pansari, Mridul -- Rendon, Mauricio -- Tippens, Daniel -- Hundeyin, Mautin -- Mani, Vishnu R -- Hajdu, Cristina -- Engle, Dannielle -- Miller, George -- CA155649/CA/NCI NIH HHS/ -- CA168611/CA/NCI NIH HHS/ -- CA193111/CA/NCI NIH HHS/ -- P30CA016087/CA/NCI NIH HHS/ -- R01 CA168611/CA/NCI NIH HHS/ -- T32 CA193111/CA/NCI NIH HHS/ -- UL1 TR000038/TR/NCATS NIH HHS/ -- England -- Nature. 2016 Apr 14;532(7598):245-9. doi: 10.1038/nature17403.

    Lens regeneration using endogenous stem cells with gain of visual function (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-03-10
    Description: The repair and regeneration of tissues using endogenous stem cells represents an ultimate goal in regenerative medicine. To our knowledge, human lens regeneration has not yet been demonstrated. Currently, the only treatment for cataracts, the leading cause of blindness worldwide, is to extract the cataractous lens and implant an artificial intraocular lens. However, this procedure poses notable risks of complications. Here we isolate lens epithelial stem/progenitor cells (LECs) in mammals and show that Pax6 and Bmi1 are required for LEC renewal. We design a surgical method of cataract removal that preserves endogenous LECs and achieves functional lens regeneration in rabbits and macaques, as well as in human infants with cataracts. Our method differs conceptually from current practice, as it preserves endogenous LECs and their natural environment maximally, and regenerates lenses with visual function. Our approach demonstrates a novel treatment strategy for cataracts and provides a new paradigm for tissue regeneration using endogenous stem cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Haotian -- Ouyang, Hong -- Zhu, Jie -- Huang, Shan -- Liu, Zhenzhen -- Chen, Shuyi -- Cao, Guiqun -- Li, Gen -- Signer, Robert A J -- Xu, Yanxin -- Chung, Christopher -- Zhang, Ying -- Lin, Danni -- Patel, Sherrina -- Wu, Frances -- Cai, Huimin -- Hou, Jiayi -- Wen, Cindy -- Jafari, Maryam -- Liu, Xialin -- Luo, Lixia -- Zhu, Jin -- Qiu, Austin -- Hou, Rui -- Chen, Baoxin -- Chen, Jiangna -- Granet, David -- Heichel, Christopher -- Shang, Fu -- Li, Xuri -- Krawczyk, Michal -- Skowronska-Krawczyk, Dorota -- Wang, Yujuan -- Shi, William -- Chen, Daniel -- Zhong, Zheng -- Zhong, Sheng -- Zhang, Liangfang -- Chen, Shaochen -- Morrison, Sean J -- Maas, Richard L -- Zhang, Kang -- Liu, Yizhi -- R37 AG024945/AG/NIA NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2016 Mar 17;531(7594):323-8. doi: 10.1038/nature17181.

    sFRP2 in the aged microenvironment drives melanoma metastasis and therapy resistance (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-04-05
    Description: Cancer is a disease of ageing. Clinically, aged cancer patients tend to have a poorer prognosis than young. This may be due to accumulated cellular damage, decreases in adaptive immunity, and chronic inflammation. However, the effects of the aged microenvironment on tumour progression have been largely unexplored. Since dermal fibroblasts can have profound impacts on melanoma progression, we examined whether age-related changes in dermal fibroblasts could drive melanoma metastasis and response to targeted therapy. Here we find that aged fibroblasts secrete a Wnt antagonist, sFRP2, which activates a multi-step signalling cascade in melanoma cells that results in a decrease in beta-catenin and microphthalmia-associated transcription factor (MITF), and ultimately the loss of a key redox effector, APE1. Loss of APE1 attenuates the response of melanoma cells to DNA damage induced by reactive oxygen species, rendering the cells more resistant to targeted therapy (vemurafenib). Age-related increases in sFRP2 also augment both angiogenesis and metastasis of melanoma cells. These data provide an integrated view of how fibroblasts in the aged microenvironment contribute to tumour progression, offering new possibilities for the design of therapy for the elderly.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4833579/" 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/PMC4833579/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaur, Amanpreet -- Webster, Marie R -- Marchbank, Katie -- Behera, Reeti -- Ndoye, Abibatou -- Kugel, Curtis H 3rd -- Dang, Vanessa M -- Appleton, Jessica -- O'Connell, Michael P -- Cheng, Phil -- Valiga, Alexander A -- Morissette, Rachel -- McDonnell, Nazli B -- Ferrucci, Luigi -- Kossenkov, Andrew V -- Meeth, Katrina -- Tang, Hsin-Yao -- Yin, Xiangfan -- Wood, William H 3rd -- Lehrmann, Elin -- Becker, Kevin G -- Flaherty, Keith T -- Frederick, Dennie T -- Wargo, Jennifer A -- Cooper, Zachary A -- Tetzlaff, Michael T -- Hudgens, Courtney -- Aird, Katherine M -- Zhang, Rugang -- Xu, Xiaowei -- Liu, Qin -- Bartlett, Edmund -- Karakousis, Giorgos -- Eroglu, Zeynep -- Lo, Roger S -- Chan, Matthew -- Menzies, Alexander M -- Long, Georgina V -- Johnson, Douglas B -- Sosman, Jeffrey -- Schilling, Bastian -- Schadendorf, Dirk -- Speicher, David W -- Bosenberg, Marcus -- Ribas, Antoni -- Weeraratna, Ashani T -- P01 CA 114046-06/CA/NCI NIH HHS/ -- P01 CA114046/CA/NCI NIH HHS/ -- P30 CA010815/CA/NCI NIH HHS/ -- P50 CA093372/CA/NCI NIH HHS/ -- R01 CA174746/CA/NCI NIH HHS/ -- R01 CA174746-01/CA/NCI NIH HHS/ -- T32 CA009171/CA/NCI NIH HHS/ -- T32 CA9171-36/CA/NCI NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2016 Apr 14;532(7598):250-4. doi: 10.1038/nature17392.

    Description: Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related death. Non-alcoholic fatty liver disease (NAFLD) affects a large proportion of the US population and is considered to be a metabolic predisposition to liver cancer. However, the role of adaptive immune responses in NAFLD-promoted HCC is largely unknown. Here we show, in mouse models and human samples, that dysregulation of lipid metabolism in NAFLD causes a selective loss of intrahepatic CD4(+) but not CD8(+) T lymphocytes, leading to accelerated hepatocarcinogenesis. We also demonstrate that CD4(+) T lymphocytes have greater mitochondrial mass than CD8(+) T lymphocytes and generate higher levels of mitochondrially derived reactive oxygen species (ROS). Disruption of mitochondrial function by linoleic acid, a fatty acid accumulated in NAFLD, causes more oxidative damage than other free fatty acids such as palmitic acid, and mediates selective loss of intrahepatic CD4(+) T lymphocytes. In vivo blockade of ROS reversed NAFLD-induced hepatic CD4(+) T lymphocyte decrease and delayed NAFLD-promoted HCC. Our results provide an unexpected link between lipid dysregulation and impaired anti-tumour surveillance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4786464/" 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/PMC4786464/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ma, Chi -- Kesarwala, Aparna H -- Eggert, Tobias -- Medina-Echeverz, Jose -- Kleiner, David E -- Jin, Ping -- Stroncek, David F -- Terabe, Masaki -- Kapoor, Veena -- ElGindi, Mei -- Han, Miaojun -- Thornton, Angela M -- Zhang, Haibo -- Egger, Michele -- Luo, Ji -- Felsher, Dean W -- McVicar, Daniel W -- Weber, Achim -- Heikenwalder, Mathias -- Greten, Tim F -- ZIA BC011345-06/Intramural NIH HHS/ -- ZIABC011303/PHS HHS/ -- England -- Nature. 2016 Mar 10;531(7593):253-7. doi: 10.1038/nature16969.
