Description: The somatic mutations present in the genome of a cell accumulate over the lifetime of a multicellular organism. These mutations can provide insights into the developmental lineage tree, the number of divisions that each cell has undergone and the mutational processes that have been operative. Here we describe whole genomes of clonal lines derived from multiple tissues of healthy mice. Using somatic base substitutions, we reconstructed the early cell divisions of each animal, demonstrating the contributions of embryonic cells to adult tissues. Differences were observed between tissues in the numbers and types of mutations accumulated by each cell, which likely reflect differences in the number of cell divisions they have undergone and varying contributions of different mutational processes. If somatic mutation rates are similar to those in mice, the results indicate that precise insights into development and mutagenesis of normal human cells will be possible.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4227286/" 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/PMC4227286/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Behjati, Sam -- Huch, Meritxell -- van Boxtel, Ruben -- Karthaus, Wouter -- Wedge, David C -- Tamuri, Asif U -- Martincorena, Inigo -- Petljak, Mia -- Alexandrov, Ludmil B -- Gundem, Gunes -- Tarpey, Patrick S -- Roerink, Sophie -- Blokker, Joyce -- Maddison, Mark -- Mudie, Laura -- Robinson, Ben -- Nik-Zainal, Serena -- Campbell, Peter -- Goldman, Nick -- van de Wetering, Marc -- Cuppen, Edwin -- Clevers, Hans -- Stratton, Michael R -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- 092096/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- 104151/Wellcome Trust/United Kingdom -- WT100183MA/Wellcome Trust/United Kingdom -- England -- Nature. 2014 Sep 18;513(7518):422-5. doi: 10.1038/nature13448.

Description: Blood cells derive from hematopoietic stem cells through stepwise fating events. To characterize gene expression programs driving lineage choice, we sequenced RNA from eight primary human hematopoietic progenitor populations representing the major myeloid commitment stages and the main lymphoid stage. We identified extensive cell type-specific expression changes: 6711 genes and 10,724 transcripts, enriched in non-protein-coding elements at early stages of differentiation. In addition, we found 7881 novel splice junctions and 2301 differentially used alternative splicing events, enriched in genes involved in regulatory processes. We demonstrated experimentally cell-specific isoform usage, identifying nuclear factor I/B (NFIB) as a regulator of megakaryocyte maturation-the platelet precursor. Our data highlight the complexity of fating events in closely related progenitor populations, the understanding of which is essential for the advancement of transplantation and regenerative medicine.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4254742/" 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/PMC4254742/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Lu -- Kostadima, Myrto -- Martens, Joost H A -- Canu, Giovanni -- Garcia, Sara P -- Turro, Ernest -- Downes, Kate -- Macaulay, Iain C -- Bielczyk-Maczynska, Ewa -- Coe, Sophia -- Farrow, Samantha -- Poudel, Pawan -- Burden, Frances -- Jansen, Sjoert B G -- Astle, William J -- Attwood, Antony -- Bariana, Tadbir -- de Bono, Bernard -- Breschi, Alessandra -- Chambers, John C -- BRIDGE Consortium -- Choudry, Fizzah A -- Clarke, Laura -- Coupland, Paul -- van der Ent, Martijn -- Erber, Wendy N -- Jansen, Joop H -- Favier, Remi -- Fenech, Matthew E -- Foad, Nicola -- Freson, Kathleen -- van Geet, Chris -- Gomez, Keith -- Guigo, Roderic -- Hampshire, Daniel -- Kelly, Anne M -- Kerstens, Hindrik H D -- Kooner, Jaspal S -- Laffan, Michael -- Lentaigne, Claire -- Labalette, Charlotte -- Martin, Tiphaine -- Meacham, Stuart -- Mumford, Andrew -- Nurnberg, Sylvia -- Palumbo, Emilio -- van der Reijden, Bert A -- Richardson, David -- Sammut, Stephen J -- Slodkowicz, Greg -- Tamuri, Asif U -- Vasquez, Louella -- Voss, Katrin -- Watt, Stephen -- Westbury, Sarah -- Flicek, Paul -- Loos, Remco -- Goldman, Nick -- Bertone, Paul -- Read, Randy J -- Richardson, Sylvia -- Cvejic, Ana -- Soranzo, Nicole -- Ouwehand, Willem H -- Stunnenberg, Hendrik G -- Frontini, Mattia -- Rendon, Augusto -- 082961/Wellcome Trust/United Kingdom -- 082961/Z/07/Z/Wellcome Trust/United Kingdom -- 084183/Z/07/Z/Wellcome Trust/United Kingdom -- 095908/Wellcome Trust/United Kingdom -- 100140/Wellcome Trust/United Kingdom -- C45041/A14953/Cancer Research UK/United Kingdom -- FS/12/27/29405/British Heart Foundation/United Kingdom -- MC_UP_0801/1/Medical Research Council/United Kingdom -- MR/J011711/1/Medical Research Council/United Kingdom -- MR/K006584/1/Medical Research Council/United Kingdom -- MR/K023489/1/Medical Research Council/United Kingdom -- RG/09/012/28096/British Heart Foundation/United Kingdom -- RG/09/12/28096/British Heart Foundation/United Kingdom -- RP-PG-0310-1002/British Heart Foundation/United Kingdom -- RP-PG-0310-1002/Department of Health/United Kingdom -- WT091310/Wellcome Trust/United Kingdom -- WT098051/Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2014 Sep 26;345(6204):1251033. doi: 10.1126/science.1251033.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1SA, UK.

Description: Sequence Logos and its variants are the most commonly used method for visualization of multiple sequence alignments (MSAs) and sequence motifs. They provide consensus-based summaries of the sequences in the alignment. Consequently, individual sequences cannot be identified in the visualization and covariant sites are not easily discernible. We recently proposed Sequence Bundles , a motif visualization technique that maintains a one-to-one relationship between sequences and their graphical representation and visualizes covariant sites. We here present Alvis, an open-source platform for the joint explorative analysis of MSAs and phylogenetic trees, employing Sequence Bundles as its main visualization method. Alvis combines the power of the visualization method with an interactive toolkit allowing detection of covariant sites, annotation of trees with synapomorphies and homoplasies, and motif detection. It also offers numerical analysis functionality, such as dimension reduction and classification. Alvis is user-friendly, highly customizable and can export results in publication-quality figures. It is available as a full-featured standalone version ( http://www.bitbucket.org/rfs/alvis ) and its Sequence Bundles visualization module is further available as a web application ( http://science-practice.com/projects/sequence-bundles ).
