Description: Systematic genetic approaches have provided deep insight into the molecular and cellular mechanisms that operate in simple unicellular organisms. For multicellular organisms, however, the pleiotropy of gene function has largely restricted such approaches to the study of early embryogenesis. With the availability of genome-wide transgenic RNA interference (RNAi) libraries in Drosophila, it is now possible to perform a systematic genetic dissection of any cell or tissue type at any stage of the lifespan. Here we apply these methods to define the genetic basis for formation and function of the Drosophila muscle. We identify a role in muscle for 2,785 genes, many of which we assign to specific functions in the organization of muscles, myofibrils or sarcomeres. Many of these genes are phylogenetically conserved, including genes implicated in mammalian sarcomere organization and human muscle diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schnorrer, Frank -- Schonbauer, Cornelia -- Langer, Christoph C H -- Dietzl, Georg -- Novatchkova, Maria -- Schernhuber, Katharina -- Fellner, Michaela -- Azaryan, Anna -- Radolf, Martin -- Stark, Alexander -- Keleman, Krystyna -- Dickson, Barry J -- England -- Nature. 2010 Mar 11;464(7286):287-91. doi: 10.1038/nature08799.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institute of Biochemistry, Am Klopferspitz 18, 82152 Martinsried, Germany. schnorrer@biochem.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20220848" target="_blank"〉PubMed〈/a〉

Description: The comparison of related genomes has emerged as a powerful lens for genome interpretation. Here we report the sequencing and comparative analysis of 29 eutherian genomes. We confirm that at least 5.5% of the human genome has undergone purifying selection, and locate constrained elements covering approximately 4.2% of the genome. We use evolutionary signatures and comparisons with experimental data sets to suggest candidate functions for approximately 60% of constrained bases. These elements reveal a small number of new coding exons, candidate stop codon readthrough events and over 10,000 regions of overlapping synonymous constraint within protein-coding exons. We find 220 candidate RNA structural families, and nearly a million elements overlapping potential promoter, enhancer and insulator regions. We report specific amino acid residues that have undergone positive selection, 280,000 non-coding elements exapted from mobile elements and more than 1,000 primate- and human-accelerated elements. Overlap with disease-associated variants indicates that our findings will be relevant for studies of human biology, health and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3207357/" 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/PMC3207357/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lindblad-Toh, Kerstin -- Garber, Manuel -- Zuk, Or -- Lin, Michael F -- Parker, Brian J -- Washietl, Stefan -- Kheradpour, Pouya -- Ernst, Jason -- Jordan, Gregory -- Mauceli, Evan -- Ward, Lucas D -- Lowe, Craig B -- Holloway, Alisha K -- Clamp, Michele -- Gnerre, Sante -- Alfoldi, Jessica -- Beal, Kathryn -- Chang, Jean -- Clawson, Hiram -- Cuff, James -- Di Palma, Federica -- Fitzgerald, Stephen -- Flicek, Paul -- Guttman, Mitchell -- Hubisz, Melissa J -- Jaffe, David B -- Jungreis, Irwin -- Kent, W James -- Kostka, Dennis -- Lara, Marcia -- Martins, Andre L -- Massingham, Tim -- Moltke, Ida -- Raney, Brian J -- Rasmussen, Matthew D -- Robinson, Jim -- Stark, Alexander -- Vilella, Albert J -- Wen, Jiayu -- Xie, Xiaohui -- Zody, Michael C -- Broad Institute Sequencing Platform and Whole Genome Assembly Team -- Baldwin, Jen -- Bloom, Toby -- Chin, Chee Whye -- Heiman, Dave -- Nicol, Robert -- Nusbaum, Chad -- Young, Sarah -- Wilkinson, Jane -- Worley, Kim C -- Kovar, Christie L -- Muzny, Donna M -- Gibbs, Richard A -- Baylor College of Medicine Human Genome Sequencing Center Sequencing Team -- Cree, Andrew -- Dihn, Huyen H -- Fowler, Gerald -- Jhangiani, Shalili -- Joshi, Vandita -- Lee, Sandra -- Lewis, Lora R -- Nazareth, Lynne V -- Okwuonu, Geoffrey -- Santibanez, Jireh -- Warren, Wesley C -- Mardis, Elaine R -- Weinstock, George M -- Wilson, Richard K -- Genome Institute at Washington University -- Delehaunty, Kim -- Dooling, David -- Fronik, Catrina -- Fulton, Lucinda -- Fulton, Bob -- Graves, Tina -- Minx, Patrick -- Sodergren, Erica -- Birney, Ewan -- Margulies, Elliott H -- Herrero, Javier -- Green, Eric D -- Haussler, David -- Siepel, Adam -- Goldman, Nick -- Pollard, Katherine S -- Pedersen, Jakob S -- Lander, Eric S -- Kellis, Manolis -- 095908/Wellcome Trust/United Kingdom -- GM82901/GM/NIGMS NIH HHS/ -- R01 HG003474/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54 HG003067-09/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Oct 12;478(7370):476-82. doi: 10.1038/nature10530.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Broad Institute of Harvard and Massachusetts Institute of Technology, 7 Cambridge Center, Cambridge, Massachusetts 02142, USA. kersli@broadinstitute.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21993624" target="_blank"〉PubMed〈/a〉

Description: Myocardial infarction, a leading cause of death in the Western world, usually occurs when the fibrous cap overlying an atherosclerotic plaque in a coronary artery ruptures. The resulting exposure of blood to the atherosclerotic material then triggers thrombus formation, which occludes the artery. The importance of genetic predisposition to coronary artery disease and myocardial infarction is best documented by the predictive value of a positive family history. Next-generation sequencing in families with several affected individuals has revolutionized mutation identification. Here we report the segregation of two private, heterozygous mutations in two functionally related genes, GUCY1A3 (p.Leu163Phefs*24) and CCT7 (p.Ser525Leu), in an extended myocardial infarction family. GUCY1A3 encodes the alpha1 subunit of soluble guanylyl cyclase (alpha1-sGC), and CCT7 encodes CCTeta, a member of the tailless complex polypeptide 1 ring complex, which, among other functions, stabilizes soluble guanylyl cyclase. After stimulation with nitric oxide, soluble guanylyl cyclase generates cGMP, which induces vasodilation and inhibits platelet activation. We demonstrate in vitro that mutations in both GUCY1A3 and CCT7 severely reduce alpha1-sGC as well as beta1-sGC protein content, and impair soluble guanylyl cyclase activity. Moreover, platelets from digenic mutation carriers contained less soluble guanylyl cyclase protein and consequently displayed reduced nitric-oxide-induced cGMP formation. Mice deficient in alpha1-sGC protein displayed accelerated thrombus formation in the microcirculation after local trauma. Starting with a severely affected family, we have identified a link between impaired soluble-guanylyl-cyclase-dependent nitric oxide signalling and myocardial infarction risk, possibly through accelerated thrombus formation. Reversing this defect may provide a new therapeutic target for reducing the risk of myocardial infarction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Erdmann, Jeanette -- Stark, Klaus -- Esslinger, Ulrike B -- Rumpf, Philipp Moritz -- Koesling, Doris -- de Wit, Cor -- Kaiser, Frank J -- Braunholz, Diana -- Medack, Anja -- Fischer, Marcus -- Zimmermann, Martina E -- Tennstedt, Stephanie -- Graf, Elisabeth -- Eck, Sebastian -- Aherrahrou, Zouhair -- Nahrstaedt, Janja -- Willenborg, Christina -- Bruse, Petra -- Braenne, Ingrid -- Nothen, Markus M -- Hofmann, Per -- Braund, Peter S -- Mergia, Evanthia -- Reinhard, Wibke -- Burgdorf, Christof -- Schreiber, Stefan -- Balmforth, Anthony J -- Hall, Alistair S -- Bertram, Lars -- Steinhagen-Thiessen, Elisabeth -- Li, Shu-Chen -- Marz, Winfried -- Reilly, Muredach -- Kathiresan, Sekar -- McPherson, Ruth -- Walter, Ulrich -- CARDIoGRAM -- Ott, Jurg -- Samani, Nilesh J -- Strom, Tim M -- Meitinger, Thomas -- Hengstenberg, Christian -- Schunkert, Heribert -- British Heart Foundation/United Kingdom -- England -- Nature. 2013 Dec 19;504(7480):432-6. doi: 10.1038/nature12722.
