IκB proteins are the primary inhibitors of NF-κB. Here, we demonstrate that sumoylated and phosphorylated IκBα accumulates in the nucleus of keratinocytes and interacts with histones H2A and H4 at the regulatory region of ...

Invasive malignant melanoma (MM) is an aggressive tumor with no curative therapy available in advanced stages. Nuclear corepressor (NCoR) is an essential regulator of gene transcription, and its function has been found ...
HER-family ligands promote acquired resistance to trastuzumab in gastric cancer

Sampera Borràs, Aïda, 1990-; Sánchez-Martín, Francisco Javier; Arpí Llucià, Oriol; Visa Turmo, Laura; Iglesias Coma, Mar; Menéndez, Silvia; Gaye, Élisabeth; Dalmases Massegú, Alba, 1982-; Clavé Safont, Sergi; Gelabert-Baldrich, Mariona; Tuxen Poulsen, Thomas; Kragh, Michael; Bellosillo Paricio, Beatriz; Albanell Mestres, Joan; Rovira Guerín, Ana; Rovira Guerín, Ana; Montagut Viladot, Clara (American Association for Cancer Research (AACR), 2019)

Despite the clinical benefit of trastuzumab, eventually all HER2-amplified gastric cancer tumors develop drug resistance. We aimed to identify molecular mechanisms of acquired resistance to trastuzumab in gastric cancer ...
Inhibition of specific NF-KB activity contributes to the tumor suppressor function of 14-3-3omega in breast cancer

Inglés Esteve, Julia; Morales, Mònica; Dalmases Massegú, Alba, 1982-; Garcia Carbonell, Ricard; Jené i Sanz, Alba, 1984-; López Bigas, Núria; Iglesias Coma, Mar; Ruiz Herguido, Cristina; Rovira Guerín, Ana; Rojo, Federico; Albanell Mestres, Joan; Gomis, Roger R.; Bigas Salvans, Anna; Espinosa Blay, Lluís (Public Library of Science (PLoS), 2012)

14-3-3σ is frequently lost in human breast cancers by genetic deletion or promoter methylation. We have now investigated the involvement of 14-3-3σ in the termination of NF-κB signal in mammary cells and its putative role ...
