    Induced pluripotent stem cells generated from patients with ALS can be differentiated into motor neurons (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-08-02
    Description: The generation of pluripotent stem cells from an individual patient would enable the large-scale production of the cell types affected by that patient's disease. These cells could in turn be used for disease modeling, drug discovery, and eventually autologous cell replacement therapies. Although recent studies have demonstrated the reprogramming of human fibroblasts to a pluripotent state, it remains unclear whether these induced pluripotent stem (iPS) cells can be produced directly from elderly patients with chronic disease. We have generated iPS cells from an 82-year-old woman diagnosed with a familial form of amyotrophic lateral sclerosis (ALS). These patient-specific iPS cells possess properties of embryonic stem cells and were successfully directed to differentiate into motor neurons, the cell type destroyed in ALS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dimos, John T -- Rodolfa, Kit T -- Niakan, Kathy K -- Weisenthal, Laurin M -- Mitsumoto, Hiroshi -- Chung, Wendy -- Croft, Gist F -- Saphier, Genevieve -- Leibel, Rudy -- Goland, Robin -- Wichterle, Hynek -- Henderson, Christopher E -- Eggan, Kevin -- New York, N.Y. -- Science. 2008 Aug 29;321(5893):1218-21. doi: 10.1126/science.1158799.

    Mutations in the pericentrin (PCNT) gene cause primordial dwarfism (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-01-05
    Description: Fundamental processes influencing human growth can be revealed by studying extreme short stature. Using genetic linkage analysis, we find that biallelic loss-of-function mutations in the centrosomal pericentrin (PCNT) gene on chromosome 21q22.3 cause microcephalic osteodysplastic primordial dwarfism type II (MOPD II) in 25 patients. Adults with this rare inherited condition have an average height of 100 centimeters and a brain size comparable to that of a 3-month-old baby, but are of near-normal intelligence. Absence of PCNT results in disorganized mitotic spindles and missegregation of chromosomes. Mutations in related genes are known to cause primary microcephaly (MCPH1, CDK5RAP2, ASPM, and CENPJ).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rauch, Anita -- Thiel, Christian T -- Schindler, Detlev -- Wick, Ursula -- Crow, Yanick J -- Ekici, Arif B -- van Essen, Anthonie J -- Goecke, Timm O -- Al-Gazali, Lihadh -- Chrzanowska, Krystyna H -- Zweier, Christiane -- Brunner, Han G -- Becker, Kristin -- Curry, Cynthia J -- Dallapiccola, Bruno -- Devriendt, Koenraad -- Dorfler, Arnd -- Kinning, Esther -- Megarbane, Andre -- Meinecke, Peter -- Semple, Robert K -- Spranger, Stephanie -- Toutain, Annick -- Trembath, Richard C -- Voss, Egbert -- Wilson, Louise -- Hennekam, Raoul -- de Zegher, Francis -- Dorr, Helmuth-Gunther -- Reis, Andre -- 062346/Z/00/Z/Wellcome Trust/United Kingdom -- 080952/Z/06/Z/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2008 Feb 8;319(5864):816-9. doi: 10.1126/science.1151174.

    The genomic landscapes of human breast and colorectal cancers (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-13
    Description: Human cancer is caused by the accumulation of mutations in oncogenes and tumor suppressor genes. To catalog the genetic changes that occur during tumorigenesis, we isolated DNA from 11 breast and 11 colorectal tumors and determined the sequences of the genes in the Reference Sequence database in these samples. Based on analysis of exons representing 20,857 transcripts from 18,191 genes, we conclude that the genomic landscapes of breast and colorectal cancers are composed of a handful of commonly mutated gene "mountains" and a much larger number of gene "hills" that are mutated at low frequency. We describe statistical and bioinformatic tools that may help identify mutations with a role in tumorigenesis. These results have implications for understanding the nature and heterogeneity of human cancers and for using personal genomics for tumor diagnosis and therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wood, Laura D -- Parsons, D Williams -- Jones, Sian -- Lin, Jimmy -- Sjoblom, Tobias -- Leary, Rebecca J -- Shen, Dong -- Boca, Simina M -- Barber, Thomas -- Ptak, Janine -- Silliman, Natalie -- Szabo, Steve -- Dezso, Zoltan -- Ustyanksky, Vadim -- Nikolskaya, Tatiana -- Nikolsky, Yuri -- Karchin, Rachel -- Wilson, Paul A -- Kaminker, Joshua S -- Zhang, Zemin -- Croshaw, Randal -- Willis, Joseph -- Dawson, Dawn -- Shipitsin, Michail -- Willson, James K V -- Sukumar, Saraswati -- Polyak, Kornelia -- Park, Ben Ho -- Pethiyagoda, Charit L -- Pant, P V Krishna -- Ballinger, Dennis G -- Sparks, Andrew B -- Hartigan, James -- Smith, Douglas R -- Suh, Erick -- Papadopoulos, Nickolas -- Buckhaults, Phillip -- Markowitz, Sanford D -- Parmigiani, Giovanni -- Kinzler, Kenneth W -- Velculescu, Victor E -- Vogelstein, Bert -- CA 43460/CA/NCI NIH HHS/ -- CA 57345/CA/NCI NIH HHS/ -- CA109274/CA/NCI NIH HHS/ -- CA112828/CA/NCI NIH HHS/ -- CA121113/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- GM070219/GM/NIGMS NIH HHS/ -- GM07309/GM/NIGMS NIH HHS/ -- P30-CA43703/CA/NCI NIH HHS/ -- RR017698/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 16;318(5853):1108-13.

    Two chemoreceptors mediate developmental effects of dauer pheromone in C. elegans (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-10-03
    Description: Intraspecific chemical communication is mediated by signals called pheromones. Caenorhabditis elegans secretes a mixture of small molecules (collectively termed dauer pheromone) that regulates entry into the alternate dauer larval stage and also modulates adult behavior via as yet unknown receptors. Here, we identify two heterotrimeric GTP-binding protein (G protein)-coupled receptors (GPCRs) that mediate dauer formation in response to a subset of dauer pheromone components. The SRBC-64 and SRBC-66 GPCRs are members of the large Caenorhabditis-specific SRBC subfamily and are expressed in the ASK chemosensory neurons, which are required for pheromone-induced dauer formation. Expression of both, but not each receptor alone, confers pheromone-mediated effects on heterologous cells. Identification of dauer pheromone receptors will allow a better understanding of the signaling cascades that transduce the context-dependent effects of ecologically important chemical signals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4448937/" 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/PMC4448937/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Kyuhyung -- Sato, Koji -- Shibuya, Mayumi -- Zeiger, Danna M -- Butcher, Rebecca A -- Ragains, Justin R -- Clardy, Jon -- Touhara, Kazushige -- Sengupta, Piali -- F32 GM077943/GM/NIGMS NIH HHS/ -- P30 NS045713/NS/NINDS NIH HHS/ -- P30 NS45713/NS/NINDS NIH HHS/ -- R01 CA024487/CA/NCI NIH HHS/ -- R01 CA24487/CA/NCI NIH HHS/ -- R01 GM056223/GM/NIGMS NIH HHS/ -- R01 GM56223/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):994-8. doi: 10.1126/science.1176331.

    Netrins promote developmental and therapeutic angiogenesis (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-01
    Description: Axonal guidance and vascular patterning share several guidance cues, including proteins in the netrin family. We demonstrate that netrins stimulate proliferation, migration, and tube formation of human endothelial cells in vitro and that this stimulation is independent of known netrin receptors. Suppression of netrin1a messenger RNA in zebrafish inhibits vascular sprouting, implying a proangiogenic role for netrins during vertebrate development. We also show that netrins accelerate neovascularization in an in vivo model of ischemia and that they reverse neuropathy and vasculopathy in a diabetic murine model. We propose that the attractive vascular and neural guidance functions of netrins offer a unique therapeutic potential.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2577078/" 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/PMC2577078/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, Brent D -- Ii, Masaaki -- Park, Kye Won -- Suli, Arminda -- Sorensen, Lise K -- Larrieu-Lahargue, Frederic -- Urness, Lisa D -- Suh, Wonhee -- Asai, Jun -- Kock, Gerhardus A H -- Thorne, Tina -- Silver, Marcy -- Thomas, Kirk R -- Chien, Chi-Bin -- Losordo, Douglas W -- Li, Dean Y -- R01 HL068873/HL/NHLBI NIH HHS/ -- R01 HL077671/HL/NHLBI NIH HHS/ -- R01 HL077671-03/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2006 Aug 4;313(5787):640-4.

    5'-Triphosphate RNA is the ligand for RIG-I (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-10-14
    Description: The structural basis for the distinction of viral RNA from abundant self RNA in the cytoplasm of virally infected cells is largely unknown. We demonstrated that the 5'-triphosphate end of RNA generated by viral polymerases is responsible for retinoic acid-inducible protein I (RIG-I)-mediated detection of RNA molecules. Detection of 5'-triphosphate RNA is abrogated by capping of the 5'-triphosphate end or by nucleoside modification of RNA, both occurring during posttranscriptional RNA processing in eukaryotes. Genomic RNA prepared from a negative-strand RNA virus and RNA prepared from virus-infected cells (but not from noninfected cells) triggered a potent interferon-alpha response in a phosphatase-sensitive manner. 5'-triphosphate RNA directly binds to RIG-I. Thus, uncapped 5'-triphosphate RNA (now termed 3pRNA) present in viruses known to be recognized by RIG-I, but absent in viruses known to be detected by MDA-5 such as the picornaviruses, serves as the molecular signature for the detection of viral infection by RIG-I.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hornung, Veit -- Ellegast, Jana -- Kim, Sarah -- Brzozka, Krzysztof -- Jung, Andreas -- Kato, Hiroki -- Poeck, Hendrik -- Akira, Shizuo -- Conzelmann, Karl-Klaus -- Schlee, Martin -- Endres, Stefan -- Hartmann, Gunther -- New York, N.Y. -- Science. 2006 Nov 10;314(5801):994-7.

    Recognition of a ubiquitous self antigen by prostate cancer-infiltrating CD8+ T lymphocytes (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-01-12
    Description: Substantial evidence exists that many tumors can be specifically recognized by CD8+ T lymphocytes. The definition of antigens targeted by these cells is paramount for the development of effective immunotherapeutic strategies for treating human cancers. In a screen for endogenous tumor-associated T cell responses in a primary mouse model of prostatic adenocarcinoma, we identified a naturally arising CD8+ T cell response that is reactive to a peptide derived from histone H4. Despite the ubiquitous nature of histones, T cell recognition of histone H4 peptide was specifically associated with the presence of prostate cancer in these mice. Thus, the repertoire of antigens recognized by tumor-infiltrating T cells is broader than previously thought and includes peptides derived from ubiquitous self antigens that are normally sequestered from immune detection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Savage, Peter A -- Vosseller, Keith -- Kang, Chulho -- Larimore, Kevin -- Riedel, Elyn -- Wojnoonski, Kathleen -- Jungbluth, Achim A -- Allison, James P -- New York, N.Y. -- Science. 2008 Jan 11;319(5860):215-20. doi: 10.1126/science.1148886.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, Howard Hughes Medical Institute, and Ludwig Center for Cancer Immunotherapy, Memorial Sloan-Kettering Cancer Center (MSKCC), New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18187659" target="_blank"〉PubMed〈/a〉

    Generation of functional ventricular heart muscle from mouse ventricular progenitor cells (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-10-17
    Description: The mammalian heart is formed from distinct sets of first and second heart field (FHF and SHF, respectively) progenitors. Although multipotent progenitors have previously been shown to give rise to cardiomyocytes, smooth muscle, and endothelial cells, the mechanism governing the generation of large numbers of differentiated progeny remains poorly understood. We have employed a two-colored fluorescent reporter system to isolate FHF and SHF progenitors from developing mouse embryos and embryonic stem cells. Genome-wide profiling of coding and noncoding transcripts revealed distinct molecular signatures of these progenitor populations. We further identify a committed ventricular progenitor cell in the Islet 1 lineage that is capable of limited in vitro expansion, differentiation, and assembly into functional ventricular muscle tissue, representing a combination of tissue engineering and stem cell biology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2895998/" 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/PMC2895998/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Domian, Ibrahim J -- Chiravuri, Murali -- van der Meer, Peter -- Feinberg, Adam W -- Shi, Xi -- Shao, Ying -- Wu, Sean M -- Parker, Kevin Kit -- Chien, Kenneth R -- K08 HL081086/HL/NHLBI NIH HHS/ -- K08 HL081086-01/HL/NHLBI NIH HHS/ -- K08 HL091209/HL/NHLBI NIH HHS/ -- R01 HL079126/HL/NHLBI NIH HHS/ -- R01 HL079126-01A1/HL/NHLBI NIH HHS/ -- T32 HL002807/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 16;326(5951):426-9. doi: 10.1126/science.1177350.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cardiovascular Research Center, Massachusetts General Hospital, Charles River Plaza, CPZN 3200, 185 Cambridge Street, Boston, MA 02114-2790, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19833966" target="_blank"〉PubMed〈/a〉

    Detection of an infectious retrovirus, XMRV, in blood cells of patients with chronic fatigue syndrome (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-10-10
    Description: Chronic fatigue syndrome (CFS) is a debilitating disease of unknown etiology that is estimated to affect 17 million people worldwide. Studying peripheral blood mononuclear cells (PBMCs) from CFS patients, we identified DNA from a human gammaretrovirus, xenotropic murine leukemia virus-related virus (XMRV), in 68 of 101 patients (67%) as compared to 8 of 218 (3.7%) healthy controls. Cell culture experiments revealed that patient-derived XMRV is infectious and that both cell-associated and cell-free transmission of the virus are possible. Secondary viral infections were established in uninfected primary lymphocytes and indicator cell lines after their exposure to activated PBMCs, B cells, T cells, or plasma derived from CFS patients. These findings raise the possibility that XMRV may be a contributing factor in the pathogenesis of CFS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lombardi, Vincent C -- Ruscetti, Francis W -- Das Gupta, Jaydip -- Pfost, Max A -- Hagen, Kathryn S -- Peterson, Daniel L -- Ruscetti, Sandra K -- Bagni, Rachel K -- Petrow-Sadowski, Cari -- Gold, Bert -- Dean, Michael -- Silverman, Robert H -- Mikovits, Judy A -- CA104943/CA/NCI NIH HHS/ -- HHSN26120080001E/PHS HHS/ -- New York, N.Y. -- Science. 2009 Oct 23;326(5952):585-9. doi: 10.1126/science.1179052.

    Description: Cell migration requires the transmission of motion generated in the actin cytoskeleton to the extracellular environment through a complex assembly of proteins in focal adhesions. We developed correlational fluorescent speckle microscopy to measure the coupling of focal-adhesion proteins to actin filaments. Different classes of focal-adhesion structural and regulatory molecules exhibited varying degrees of correlated motions with actin filaments, indicating hierarchical transmission of actin motion through focal adhesions. Interactions between vinculin, talin, and actin filaments appear to constitute a slippage interface between the cytoskeleton and integrins, generating a molecular clutch that is regulated during the morphodynamic transitions of cell migration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hu, Ke -- Ji, Lin -- Applegate, Kathryn T -- Danuser, Gaudenz -- Waterman-Storer, Clare M -- GM67230/GM/NIGMS NIH HHS/ -- U54GM64346/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Jan 5;315(5808):111-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, The Scripps Research Institute, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17204653" target="_blank"〉PubMed〈/a〉
