  • Paulo, Esther; García Santamarina, Sarela, 1978-; Calvo, Isabel A.; Carmona, Mercè; Boronat, Susanna; Domènech, Alba; Ayté del Olmo, José; Hidalgo Hernando, Elena (Wiley-Blackwell, 2014)
    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 ...
  • 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 ...
  • Calvo, Isabel A.; Gabrielli, Natalia, 1978-; Iglesias Baena, Iván; García Santamarina, Sarela, 1978-; Hoe, Kwang-Lae; Kim, Dong Uk; Sansó Martínez, Miriam, 1979-; Zuin, Alice, 1978-; 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. ...
  • García Santamarina, Sarela, 1978-; Boronat, Susanna; Calvo, Isabel A.; Rodríguez Gabriel, Miguel; Ayté del Olmo, José; Molina, Henrik; Hidalgo Hernando, Elena (Mary Ann Liebert, Inc, 2013)
    Cysteine oxidation mediates oxidative stress toxicity and signaling. It has been long proposed that the thioredoxin (Trx) system, which consists of Trx and thioredoxin reductase (Trr), is not only involved in recycling ...
  • Zuin, Alice, 1978-; Gabrielli, Natalia, 1978-; Calvo, Isabel A.; García Santamarina, Sarela, 1978-; 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 ...
  • Calvo, Isabel A.; Ayté del Olmo, José; Hidalgo Hernando, Elena (Company of Biologists, 2013)
    Reversible thiol oxidation is both a mark of hydrogen peroxide (H2O2) toxicity and an initiator of signalling events. H2O2 sensors contain exposed and reactive cysteine residues, which become transiently oxidized as an ...
  • Jara, Mónica; Vivancos Prellezo, Ana; Calvo, Isabel A.; Moldón Vara, 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, Esther; 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, Patrícia; 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 ...
