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

    Rare variant in scavenger receptor BI raises HDL cholesterol and increases risk of coronary heart disease (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-03-12
    Description: Scavenger receptor BI (SR-BI) is the major receptor for high-density lipoprotein (HDL) cholesterol (HDL-C). In humans, high amounts of HDL-C in plasma are associated with a lower risk of coronary heart disease (CHD). Mice that have depleted Scarb1 (SR-BI knockout mice) have markedly elevated HDL-C levels but, paradoxically, increased atherosclerosis. The impact of SR-BI on HDL metabolism and CHD risk in humans remains unclear. Through targeted sequencing of coding regions of lipid-modifying genes in 328 individuals with extremely high plasma HDL-C levels, we identified a homozygote for a loss-of-function variant, in which leucine replaces proline 376 (P376L), in SCARB1, the gene encoding SR-BI. The P376L variant impairs posttranslational processing of SR-BI and abrogates selective HDL cholesterol uptake in transfected cells, in hepatocyte-like cells derived from induced pluripotent stem cells from the homozygous subject, and in mice. Large population-based studies revealed that subjects who are heterozygous carriers of the P376L variant have significantly increased levels of plasma HDL-C. P376L carriers have a profound HDL-related phenotype and an increased risk of CHD (odds ratio = 1.79, which is statistically significant).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zanoni, Paolo -- Khetarpal, Sumeet A -- Larach, Daniel B -- Hancock-Cerutti, William F -- Millar, John S -- Cuchel, Marina -- DerOhannessian, Stephanie -- Kontush, Anatol -- Surendran, Praveen -- Saleheen, Danish -- Trompet, Stella -- Jukema, J Wouter -- De Craen, Anton -- Deloukas, Panos -- Sattar, Naveed -- Ford, Ian -- Packard, Chris -- Majumder, Abdullah al Shafi -- Alam, Dewan S -- Di Angelantonio, Emanuele -- Abecasis, Goncalo -- Chowdhury, Rajiv -- Erdmann, Jeanette -- Nordestgaard, Borge G -- Nielsen, Sune F -- Tybjaerg-Hansen, Anne -- Schmidt, Ruth Frikke -- Kuulasmaa, Kari -- Liu, Dajiang J -- Perola, Markus -- Blankenberg, Stefan -- Salomaa, Veikko -- Mannisto, Satu -- Amouyel, Philippe -- Arveiler, Dominique -- Ferrieres, Jean -- Muller-Nurasyid, Martina -- Ferrario, Marco -- Kee, Frank -- Willer, Cristen J -- Samani, Nilesh -- Schunkert, Heribert -- Butterworth, Adam S -- Howson, Joanna M M -- Peloso, Gina M -- Stitziel, Nathan O -- Danesh, John -- Kathiresan, Sekar -- Rader, Daniel J -- CHD Exome+ Consortium -- CARDIoGRAM Exome Consortium -- Global Lipids Genetics Consortium -- R01 DK089256/DK/NIDDK NIH HHS/ -- R01 HL117078/HL/NHLBI NIH HHS/ -- TL1 RR024133/RR/NCRR NIH HHS/ -- TL1R000138/PHS HHS/ -- TL1RR024133/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1166-71. doi: 10.1126/science.aad3517.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Genetics and Medicine, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA. ; Departments of Genetics and Medicine, Division of Translational Medicine and Human Genetics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA.

    The TAM family receptor tyrosine kinase TYRO3 is a negative regulator of type 2 immunity (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-04-02
    Description: Host responses against metazoan parasites or an array of environmental substances elicit type 2 immunity. Despite its protective function, type 2 immunity also drives allergic diseases. The mechanisms that regulate the magnitude of the type 2 response remain largely unknown. Here, we show that genetic ablation of a receptor tyrosine kinase encoded byTyro3in mice or the functional neutralization of its ortholog in human dendritic cells resulted in enhanced type 2 immunity. Furthermore, the TYRO3 agonist PROS1 was induced in T cells by the quintessential type 2 cytokine, interleukin-4. T cell-specificPros1knockouts phenocopied the loss ofTyro3 Thus, a PROS1-mediated feedback from adaptive immunity engages a rheostat, TYRO3, on innate immune cells to limit the intensity of type 2 responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, Pamela Y -- Carrera Silva, Eugenio A -- De Kouchkovsky, Dimitri -- Joannas, Leonel D -- Hao, Liming -- Hu, Donglei -- Huntsman, Scott -- Eng, Celeste -- Licona-Limon, Paula -- Weinstein, Jason S -- Herbert, De'Broski R -- Craft, Joseph E -- Flavell, Richard A -- Repetto, Silvia -- Correale, Jorge -- Burchard, Esteban G -- Torgerson, Dara G -- Ghosh, Sourav -- Rothlin, Carla V -- HL004464/HL/NHLBI NIH HHS/ -- HL078885/HL/NHLBI NIH HHS/ -- HL088133/HL/NHLBI NIH HHS/ -- HL104608/HL/NHLBI NIH HHS/ -- HL117004/HL/NHLBI NIH HHS/ -- MD006902/MD/NIMHD NIH HHS/ -- R01 AI089824/AI/NIAID NIH HHS/ -- T32 AI007019/AI/NIAID NIH HHS/ -- T32 GM007205/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Apr 1;352(6281):99-103. doi: 10.1126/science.aaf1358.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunobiology, School of Medicine, Yale University, New Haven, CT 06520, USA. ; Department of Immunobiology, School of Medicine, Yale University, New Haven, CT 06520, USA.

    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.

    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.

    NAFLD causes selective CD4(+) T lymphocyte loss and promotes hepatocarcinogenesis (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-03-05
    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.

    Airway acidification initiates host defense abnormalities in cystic fibrosis mice (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-01-30
    Description: Cystic fibrosis (CF) is caused by mutations in the gene that encodes the cystic fibrosis transmembrane conductance regulator (CFTR) anion channel. In humans and pigs, the loss of CFTR impairs respiratory host defenses, causing airway infection. But CF mice are spared. We found that in all three species, CFTR secreted bicarbonate into airway surface liquid. In humans and pigs lacking CFTR, unchecked H(+) secretion by the nongastric H(+)/K(+) adenosine triphosphatase (ATP12A) acidified airway surface liquid, which impaired airway host defenses. In contrast, mouse airways expressed little ATP12A and secreted minimal H(+); consequently, airway surface liquid in CF and non-CF mice had similar pH. Inhibiting ATP12A reversed host defense abnormalities in human and pig airways. Conversely, expressing ATP12A in CF mouse airways acidified airway surface liquid, impaired defenses, and increased airway bacteria. These findings help explain why CF mice are protected from infection and nominate ATP12A as a potential therapeutic target for CF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shah, Viral S -- Meyerholz, David K -- Tang, Xiao Xiao -- Reznikov, Leah -- Abou Alaiwa, Mahmoud -- Ernst, Sarah E -- Karp, Philip H -- Wohlford-Lenane, Christine L -- Heilmann, Kristopher P -- Leidinger, Mariah R -- Allen, Patrick D -- Zabner, Joseph -- McCray, Paul B Jr -- Ostedgaard, Lynda S -- Stoltz, David A -- Randak, Christoph O -- Welsh, Michael J -- 5T32GM007337/GM/NIGMS NIH HHS/ -- DK054759/DK/NIDDK NIH HHS/ -- F30 HL123239/HL/NHLBI NIH HHS/ -- F30HL123239/HL/NHLBI NIH HHS/ -- HL091842/HL/NHLBI NIH HHS/ -- HL117744/HL/NHLBI NIH HHS/ -- HL51670/HL/NHLBI NIH HHS/ -- K08HL097071/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Jan 29;351(6272):503-7. doi: 10.1126/science.aad5589.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Iowa, Iowa City, IA 52242, USA.

    Hobit and Blimp1 instruct a universal transcriptional program of tissue residency in lymphocytes (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-04-23
    Description: Tissue-resident memory T (Trm) cells permanently localize to portals of pathogen entry, where they provide immediate protection against reinfection. To enforce tissue retention, Trm cells up-regulate CD69 and down-regulate molecules associated with tissue egress; however, a Trm-specific transcriptional regulator has not been identified. Here, we show that the transcription factor Hobit is specifically up-regulated in Trm cells and, together with related Blimp1, mediates the development of Trm cells in skin, gut, liver, and kidney in mice. The Hobit-Blimp1 transcriptional module is also required for other populations of tissue-resident lymphocytes, including natural killer T (NKT) cells and liver-resident NK cells, all of which share a common transcriptional program. Our results identify Hobit and Blimp1 as central regulators of this universal program that instructs tissue retention in diverse tissue-resident lymphocyte populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mackay, Laura K -- Minnich, Martina -- Kragten, Natasja A M -- Liao, Yang -- Nota, Benjamin -- Seillet, Cyril -- Zaid, Ali -- Man, Kevin -- Preston, Simon -- Freestone, David -- Braun, Asolina -- Wynne-Jones, Erica -- Behr, Felix M -- Stark, Regina -- Pellicci, Daniel G -- Godfrey, Dale I -- Belz, Gabrielle T -- Pellegrini, Marc -- Gebhardt, Thomas -- Busslinger, Meinrad -- Shi, Wei -- Carbone, Francis R -- van Lier, Rene A W -- Kallies, Axel -- van Gisbergen, Klaas P J M -- New York, N.Y. -- Science. 2016 Apr 22;352(6284):459-63. doi: 10.1126/science.aad2035.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, The University of Melbourne, The Peter Doherty Institute for Infection and Immunity, Melbourne, Australia.

    RNA-binding proteins ZFP36L1 and ZFP36L2 promote cell quiescence (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-04-23
    Description: Progression through the stages of lymphocyte development requires coordination of the cell cycle. Such coordination ensures genomic integrity while cells somatically rearrange their antigen receptor genes [in a process called variable-diversity-joining (VDJ) recombination] and, upon successful rearrangement, expands the pools of progenitor lymphocytes. Here we show that in developing B lymphocytes, the RNA-binding proteins (RBPs) ZFP36L1 and ZFP36L2 are critical for maintaining quiescence before precursor B cell receptor (pre-BCR) expression and for reestablishing quiescence after pre-BCR-induced expansion. These RBPs suppress an evolutionarily conserved posttranscriptional regulon consisting of messenger RNAs whose protein products cooperatively promote transition into the S phase of the cell cycle. This mechanism promotes VDJ recombination and effective selection of cells expressing immunoglobulin-mu at the pre-BCR checkpoint.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Galloway, Alison -- Saveliev, Alexander -- Lukasiak, Sebastian -- Hodson, Daniel J -- Bolland, Daniel -- Balmanno, Kathryn -- Ahlfors, Helena -- Monzon-Casanova, Elisa -- Mannurita, Sara Ciullini -- Bell, Lewis S -- Andrews, Simon -- Diaz-Munoz, Manuel D -- Cook, Simon J -- Corcoran, Anne -- Turner, Martin -- Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2016 Apr 22;352(6284):453-9. doi: 10.1126/science.aad5978.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Lymphocyte Signalling and Development, The Babraham Institute, Cambridge CB22 3AT, UK. ; Laboratory of Lymphocyte Signalling and Development, The Babraham Institute, Cambridge CB22 3AT, UK.
