  • García Rodríguez, Patricia; Paulo, Esther; Gao, Jun; Wahls, Wayne P; Ayté del Olmo, José; Lowy, Ernesto; Hidalgo Hernando, Elena (Oxford University Press, 2014)
    Schizosaccharomyces pombe displays a large transcriptional response common to several stress conditions, regulated primarily by the transcription factor Atf1. Atf1-dependent promoters contain especially broad nucleosome ...
  • Calvo, Isabel A.; Boronat, Susanna; Domènech, Alba; García-Santamarina, Sarela, 1978-; Ayté del Olmo, José; Hidalgo Hernando, Elena (Elsevier, 2013)
    In fission yeast, the transcription factor Pap1 undergoes H2O2-dependent oxidation that promotes its nuclear accumulation and the activation of an antioxidant gene program. However, the mechanisms that regulate the sensitivity ...
  • Sansó Martínez, Miriam, 1979-; Vargas Pérez, Itzel; Quintales, Luis; Antequera, Francisco; Ayté del Olmo, José; Hidalgo Hernando, Elena (Oxford University Press, 2011)
    In the fission yeast, the MAP kinase Sty1 and the transcription factor Atf1 regulate up to 400 genes in response to environmental signals, and both proteins have been shown to bind to their promoters in a stress-dependent ...
  • Calvo, Isabel A.; Gabrielli, Natalia, 1978-; Iglesias Baena, Iván; García Santamarina, Sarela; Hoe, Kwang-Lae; Kim, Dong Uk; Sansó Martínez, Miriam, 1979-; Zuin, Alice; Pérez, Pilar; Ayté del Olmo, José; Hidalgo Hernando, Elena (Public Library of Science (PLoS), 2009)
    Background: An excess of caffeine is cytotoxic to all eukaryotic cell types. We aim to study how cells become tolerant to a toxic dose of this drug, and the relationship between caffeine and oxidative stress pathways. ...
  • Zuin, Alice; Carmona, Mercè; Morales Ivorra, Isabel; Gabrielli, Natalia, 1978-; Vivancos Prellezo, Ana; Ayté del Olmo, José; Hidalgo Hernando, Elena (Nature Publishing Group, 2010)
    Either calorie restriction, loss of function of the nutrient-dependent PKA or TOR/SCH9 pathways, or activation of stress defences improves longevity in different eukaryotes. However, the molecular links between glucose ...
  • Zuin, Alice, 1978-; Castellano Esteve, David; Ayté del Olmo, José; Hidalgo Hernando, Elena (Impact Journals, 2010)
    Oxidative stress constitutes the basis of physio-pathological situations such as neurodegenerative diseases and aging. However, sublethal exposure to toxic molecules such as reactive oxygen species can induce cellular ...
  • Zuin, Alice; Gabrielli, Natalia, 1978-; Calvo, Isabel A.; García Santamarina, Sarela; Hoe, Kwang-Lae; Kim, Dong Uk; Park, Han-Oh; Hayles, Jacqueline; Ayté del Olmo, José; Hidalgo Hernando, Elena (Public Library of Science (PLoS), 2008)
    Background: Oxidative stress is a probable cause of aging and associated diseases. Reactive oxygen species (ROS) originate mainly from endogenous sources, namely the mitochondria. Methodology/Principal Findings: We analyzed ...
  • Fernández Vázquez, Jorge; Vargas Pérez, Itzel; Sansó Martínez, Miriam, 1979-; Buhne, Karin; Carmona, Mercè; Paulo, Esther; Hermand, Damien; Rodríguez Gabriel, Miguel; Ayté del Olmo, José; Leidel, Sebastian; Hidalgo Hernando, Elena (Public Library of Science (PLoS), 2013)
    The Elongator complex, including the histone acetyl transferase Sin3/Elp3, was isolated as an RNA polymerase II-interacting complex, and cells deficient in Elongator subunits display transcriptional defects. However, it ...
  • Jara, Mónica; Vivancos Prellezo, Ana; Calvo, Isabel A.; Moldón, Alberto; Sansó Martínez, Miriam, 1979-; Hidalgo Hernando, Elena (American Society for Cell Biology, 2007)
    Peroxiredoxins are known to interact with hydrogen peroxide (H2O2) and to participate in oxidant scavenging, redox signal transduction, and heat-shock responses. The two-cysteine peroxiredoxin Tpx1 of Schizosaccharomyces ...
  • Boronat, Susanna; Domènech, Alba; Paulo, Ester; Calvo, Isabel A.; García Santamarina, Sarela, 1978-; García, Patrícia; Encinar del Dedo, Javier; Barcons, Anna; Serrano, Erica; Carmona, Mercè; Hidalgo Hernando, Elena (Elsevier, 2014)
    Cysteine residues, and in particular their thiolate groups, react not only with reactive oxygen species but also with electrophiles and with reactive nitrogen species. Thus, cysteine oxidation has often been linked to the ...
  • Calvo, Isabel A.; García, Patricia; Ayté del Olmo, José; Hidalgo Hernando, Elena (Oxford University Press, 2012)
    In response to hydrogen peroxide (H2O2), the transcription factor Pap1 from Schizosaccharomyces pombe regulates transcription of genes required for adaptation to oxidative stress and for tolerance to toxic drugs. H2O2 ...
