  • Encinar del Dedo, Javier; Gabrielli, Natalia, 1978-; Carmona, Mercè; Ayté del Olmo, José; Hidalgo Hernando, Elena (Public Library of Science, 2015)
    Iron is an essential cofactor, but it is also toxic at high levels. In Schizosaccharomyces pombe, the sensor glutaredoxin Grx4 guides the activity of the repressors Php4 and Fep1 to mediate a complex transcriptional response ...
  • Agirre Ortiz de Guzmán, Eneritz, 1983-; Bellora Pereyra, Nicolás; Alló, Mariano; Pagès Pinós, Amadís; Bertucci, Paola; Kornblihtt, Alberto R.; Eyras Jiménez, Eduardo (BioMed Central, 2015)
    BACKGROUND: Alternative splicing is primarily controlled by the activity of splicing factors and by the elongation of the RNA polymerase II (RNAPII). Recent experiments have suggested a new complex network of splicing ...

    The main peroxiredoxin in Schizosaccharomyces pombe, Tpx1, is important to sustain aerobic growth, and cells lacking this protein are only able to grow on solid plates under anaerobic conditions. We have found that deletion ...
  • Wright, Roni H.G.; Castellano, Giancarlo; Bonet Martínez, Jaume, 1982-; Le Dily, Francois; Font Mateu, Jofre; Ballaré, Cecilia; Nacht, A. Silvina; Soronellas, Daniel; Oliva Miguel, Baldomero; Beato, Miguel (Cold Spring Harbor Laboratory Press (CSHL Press), 2012)
    Eukaryotic gene regulation implies that transcription factors gain access to genomic information via poorly understood processes involving activation and targeting of kinases, histone-modifying enzymes, and chromatin ...
  • Gerstein, Mark B.; Djebali, Sarah; Lagarde, Julien; Pervouchine, Dmitri D.; Guigó Serra, Roderic; Tanzer, Andrea; Waterston, Robert (Nature Publishing Group, 2014)
    The transcriptome is the readout of the genome. Identifying common features in it across distant species can reveal fundamental principles. To this end, the ENCODE and modENCODE consortia have generated large amounts of ...
  • Abril Ferrando, Josep Francesc; Castelo Valdueza, Robert; Guigó Serra, Roderic (Cold Spring Harbor Laboratory Press-CSHL Press, 2005)
    We have carried out an initial analysis of the dynamics of the recent evolution of the splice-sites sequences on a large collection of human, rodent (mouse and rat), and chicken introns. Our results indicate that the ...
  • Tamborero, David; González Pérez, Abel; Pérez Llamas, Christian; Déu Pons, Jordi; Kandoth, Cyriac; Reimand, Jüri; Lawrence, Michael S.; Getz, Gad; Bader, Gary D.; Ding, Li; López Bigas, Núria (Nature Publishing Group, 2013)
    With the ability to fully sequence tumor genomes/exomes, the quest for cancer driver genes can now be undertaken in an unbiased manner. However, obtaining a complete catalog of cancer genes is difficult due to the heterogeneous ...
  • Uzkudun, Manu; Marcon, Luciano, 1983-; Sharpe, James (Wiley Blackwell, 2015)
    Parameter optimization coupled with model selection is a convenient approach to infer gene regulatory networks from experimental gene expression data, but so far it has been limited to single cells or static tissues where ...
  • Munteanu, Andreea; Cotterell, James; Solé Vicente, Ricard, 1962-; Sharpe, James (Nature Publishing Group, 2014)
    Interpreting a morphogen gradient into a single stripe of gene-expression is a fundamental unit of patterning in early embryogenesis. From both experimental data and computational studies the feed-forward motifs stand out ...
  • Plass Pórtulas, Mireya, 1982-; Eyras Jiménez, Eduardo (BioMed Central, 2006)
    Background: Alternatively spliced exons play an important role in the diversification of gene function in most metazoans and are highly regulated by conserved motifs in exons and introns. Two contradicting properties have ...
  • Jiménez, Alba; Cotterell, James; Munteanu, Andreea; Sharpe, James (Cold Spring Harbor Laboratory Press, 2015)
    To what extent does the dynamical mechanism producing a specific biological phenotype bias the ability to evolve into novel phenotypes? We use the interpretation of a morphogen gradient into a single stripe of gene expression ...
  • Pervouchine, Dmitri D.; Djebali, Sarah; Breschi, Alessandra; Prieto Barja, Pablo; Lagarde, Julien; Bussotti, Giovanni, 1983-; Monlong, Jean; Notredame, Cedric; Guigó Serra, Roderic; Gingeras, Thomas R. (Nature Pub. Group, 2015)
    Mice have been a long-standing model for human biology and disease. Here we characterize, by RNA sequencing, the transcriptional profiles of a large and heterogeneous collection of mouse tissues, augmenting the mouse ...
  • Meunier, Sylvain; Shvedunova, Maria; Van Nguyen, Nhuong; Ávila, Leonor; Vernos, Isabelle, 1959-; Akhtar, Asifa (Nature Publishing Group, 2015)
    The evolutionary conserved NSL complex is a prominent epigenetic regulator controlling expression of thousands of genes. Here we uncover a novel function of the NSL complex members in mitosis. As the cell enters mitosis, ...

    The increasing incidence of breast cancer brain metastasis in patients with otherwise well-controlled systemic cancer is a key challenge in cancer research. It is necessary to understand the properties of brain-tropic tumor ...
  • Buxadé, Maria; Lunazzi, Giulia; Minguillón, Jordi; Iborra, Salvador; Berga-Bolaños, Rosa; del Val, Margarita; Aramburu, José (Aramburu Beltrán); López Rodríguez, M. Cristina (Rockefeller University Press, 2012)
    Toll-like receptors (TLRs) engage networks of transcriptional regulators to induce genes essential for antimicrobial immunity. We report that NFAT5, previously characterized as an osmostress responsive factor, regulates ...
