  • A truncated form of IKKα is responsible for specific nuclear IKK activity in colorectal cancer
    Margalef González, Pol, 1985-; Fernández Majada, Vanessa; Villanueva, Alberto; Garcia Carbonell, Ricard; Iglesias Coma, Mar; López Muñoz, Laura; Martínez Iniesta, María; Villà i Freixa, Jordi; Mulero, María Carmen; Andreu García, Montserrat; Torres, Ferran; Mayo, Marty W.; Bigas Salvans, Anna; Espinosa Blay, Lluís (Elsevier, 2012)
    Nuclear IKKα regulates gene transcription by phosphorylating specific substrates and has been linked to cancer progression and metastasis. However, the mechanistic connection between tumorigenesis and IKKα activity remains ...
  • BRAF-induced tumorigenesis is IKKα-dependent but NF-κB-independent
    Margalef González, Pol, 1985-; Colomer Montañà, Carlota, 1990-; Villanueva, Alberto; Montagut Viladot, Clara; Iglesias Coma, Mar; Bellosillo Paricio, Beatriz; Salazar, Ramón; Martínez Iniesta, María; Bigas Salvans, Anna; Espinosa Blay, Lluís (American Association for the Advancement of Science, 2015)
    KRAS mutations contribute to cell proliferation and survival in numerous cancers, including colorectal cancers (CRC). One pathway through which mutant KRAS acts is an inflammatory pathway that involves the kinase IKK and ...
  • Chromatin-bound IκB-alpha regulates a subset of polycomb target genes in differentiation and cancer
    Mulero, María Carmen; Islam, Abul, 1978-; Margalef González, Pol, 1985-; Pecoraro, Matteo, 1984-; Toll Abelló, Agustín; Drechsel, Nils Jan Daniel, 1980-; Charneco, Cristina; Bellora Pereyra, Nicolás; Gallardo Hernández, Fernando; López Arribillaga, Erika, 1986-; Asensio Juan, Elena; Rodilla, Verónica; González, Jessica; Iglesias Coma, Mar; Albà Soler, Mar; Di Croce, Luciano; Villà i Freixa, Jordi; López Bigas, Núria; Keyes, William M., 1973-; Bigas Salvans, Anna; Espinosa Blay, Lluís (Elsevier, 2013)
    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 ...
  • Identification and characterization of an oncogenic form of IKKα in colorectal cancer
    Margalef González, Pol, 1985- (Universitat Pompeu Fabra, 2014-02-17)
    L’IKKα nuclear regula la transcripció gènica i ha estat relacionada amb la progressió del càncer i la metàstasis, tot i que la connexió mecanística no s’entén massa bé. Hem observat que les cèl·∙lules tumorals tenen una ...
  • IKKα is required in the intestinal epithelial cells for tumour stemness
    Colomer Montañà, Carlota, 1990-; Margalef González, Pol, 1985-; González, Jessica; Vert, Anna; Bigas Salvans, Anna; Espinosa Blay, Lluís (Nature Publishing Group, 2018)
    BACKGROUND: Colorectal cancer is a common cause of death in developed countries. Progression from adenoma to invasive carcinoma requires accumulation of mutations starting with the Adenomatous Polyposis Coli (Apc) gene. ...
  • IKKα kinase regulates the DNA damage response and drives chemo-resistance in cancer
    Colomer Montañà, Carlota, 1990-; Margalef González, Pol, 1985-; Villanueva, Alberto; Vert, Anna; Pecharroman, Irene; Solé, Laura; González-Farré, Mónica; Alonso, Josune; Montagut Viladot, Clara; Martínez Iniesta, María; Bertran, Joan; Borràs, Eva; Iglesias, Mar; Sabidó Aguadé, Eduard, 1981-; Bigas Salvans, Anna; Boulton, Simon J.; Espinosa Blay, Lluís (Elsevier, 2019)
    Phosphorylated IKKalpha(p45) is a nuclear active form of the IKKalpha kinase that is induced by the MAP kinases BRAF and TAK1 and promotes tumor growth independent of canonical NF-¿B signaling. Insights into the sources ...
