    Domingo Almenara, Xavier; Perera Lluna, Alexandre; Ramirez, Noelia; Canellas, Nicolau; Correig, Xavier; Brezmes, Jesus (2015-08-28)
    Article
    Accés restringit per política de l'editorial
    Metabolomics GC-MS samples involve high complexity data that must be effectively resolved to produce chemically meaningful results. Multivariate curve resolution-alternating least squares (MCR-ALS) is the most frequently ...
  • Aberrant DNA methylation in non-small cell lung cancer-associated fibroblasts 

    Vizoso, Manuel; Puig, Marta; Carmona, Francisco Javier; Maqueda, María; Velásquez, Adriana; Gómez, Antonio; Labernadie, Anna; Lugo, Roberto; Gabasa, Marta; Rigat-Brugarolas, Luis G.; Trepat, Xavier; Ramírez, Josep; Moran, Sebastian; Vidal, Enrique; Reguart, Noemí; Perera Lluna, Alexandre; Esteller, Manel; Alcaraz, Jordi (2015-12-01)
    Article
    Accés restringit per política de l'editorial
    DNA methylation profiling of TAFs reveals global demethylation and a selective impact on the TGF-beta pathway. Moreover, it suggests the fibrocyte origin of a fraction of TAFs, and identifies a novel prognostic biomarker ...
