    • Histone deacetylase inhibitors promote glioma cell death by G2 checkpoint abrogation leading to mitotic catastrophe 

      Cornago Protomártir, Marta; Garcia-Alberich, C.; Blasco Angulo, Natividad; Vall-llaura Espinosa, Núria; Nàger Grifo, Mireia; Herreros Danés, Judit; Comella i Carnicé, Joan Xavier; Sanchis, Daniel; Llovera i Tomàs, Marta (Nature Publishing Group, 2014-10-02)
      Glioblastoma multiforme is resistant to conventional anti-tumoral treatments due to its infiltrative nature and capability of relapse; therefore, research efforts focus on characterizing gliomagenesis and identifying ...
    • Impaired PLP-dependent metabolism in brain samples from Huntington disease patients and transgenic R6/1 mice 

      Sorolla Bardají, Maria Alba; Rodríguez Colman, Maria José; Vall-llaura Espinosa, Núria; Vived Maza, Celia; Fernández Nogales, Marta; Lucas, José J.; Ferrer, Isidre; Cabiscol Català, Elisa (Springer Science, Business Media, 2016-06)
      Oxidative stress has been described as important to Huntington disease (HD) progression. In a previous HD study, we identified several carbonylated proteins, including pyridoxal kinase and antiquitin, both of which are ...
    • Protein oxidation in Huntington disease 

      Sorolla Bardají, Maria Alba; Rodríguez Colman, Maria José; Vall-llaura Espinosa, Núria; Tamarit Sumalla, Jordi; Ros Salvador, Joaquim; Cabiscol Català, Elisa (Wiley, 2012-05)
      Huntington disease (HD) is an inherited neurodegenerative disorder caused by expansion of CAG repeats in the huntingtin gene, affecting initially the striatum and progressively the cortex. Oxidative stress, and consequent ...
    • Redox control of yeast Sir2 activity is involved in acetic acid resistance and longevity 

      Vall-llaura Espinosa, Núria; Mir, Noèlia; Garrido, Lourdes; Vived Maza, Celia; Cabiscol Català, Elisa (Elsevier, 2019-06)
      Yeast Sir2 is an NAD-dependent histone deacetylase related to oxidative stress and aging. In a previous study, we showed that Sir2 is regulated by S-glutathionylation of key cysteine residues located at the catalytic domain. ...
    • Reversible glutathionylation of Sir2 by monothiol glutaredoxins Grx3/4 regulates stress resistance 

      Vall-llaura Espinosa, Núria; Reverter Branchat, Gemma; Vived Maza, Celia; Weertman, Naomi; Rodríguez Colman, Maria José; Cabiscol Català, Elisa (Elsevier, 2016)
      The regulatory mechanisms of yeast Sir2, the founding member of the sirtuin family involved in oxidative stress and aging, are unknown. Redox signaling controls many cellular functions, especially under stress situations, ...
    • The FOX transcription factor Hcm1 regulates oxidative metabolism in response to early nutrient limitation in yeast. Role of Snf1 and Tor1/Sch9 kinases 

      Rodríguez Colman, Maria José; Sorolla Bardají, Maria Alba; Vall-llaura Espinosa, Núria; Tamarit Sumalla, Jordi; Ros Salvador, Joaquim; Cabiscol Català, Elisa (Elsevier, 2013)
      Within Saccharomyces cerevisiae, Hcm1is a member of the forkhead transcription factor family with a role in chromosome organization. Our group recently described its involvement in mitochondrial biogenesis and stress ...
