Matilde Lleonart Pajarin I am group leader of "Biomedical Research in Cancer Stem Cells" at VHIR. I arrived at VHIR 21 years ago after having worked in different prestigious international research centers: World Health Organization (WHO) at the International Agency for Research on Cancer (IARC) (Lyon, France), the Wolfson Institute for Biomedical Research (WIBR) in London and the Queen´s Mary University of London.

My Research Group was recognized as an Emerging Research Group in 2009 by the Generalitat de Catalunya and later in 2014 as a Consolidated Research Group. Throughout my career I have been involved in cancer research from a more molecular point of view correlating key mutations in oncogenes and tumor suppressor genes with anatomical, pathological and clinical features of patients' tumors and also through cell culture studies to determine important key cell signaling pathways in tumorigenesis. Currently, the main lines of research of my Research Group focus on the identification and characterization of biological mechanisms in resistant cancer cells, including cancer stem cells, to unravel the pathways responsible for their resistance in breast, lung and head and neck cancer models. In addition, we are particularly focused on identifying molecular targets in resistant cancer cells and cancer stem cells affecting particularly aggressive tumors. The aim is to attack them pharmacologically in order to propose new cancer therapies: new drugs and/or drug combinations to combat resistant tumors in mouse models.
Research lines Detección precoz de cáncer mamario antes de que éste se manifieste A partir de datos preliminares de arrays, hemos caracterizado algunos microRNAs/mRNAs relevantes en tumores. Actualmente los estamos analizando a nivel de pacientes con cáncer en sangre como posible método predictivo antes de la aparición del tumor. IP: Matilde Lleonart Pajarin Estudio de proteínas de unión a RNA como nuevos factores pronóstico y diagnóstico en cáncer En nuestro laboratorio hemos efectuado diversos “screenings” genéticos para detectar nuevos genes implicados en proliferación celular in vitro que además poséan un papel relevante en cáncer humano. De entre ellos descubrimos la proteínas CIRP, la cual hemos descrito como proteína oncogénica. Actualmente estamos valorando la función de CIRP en diversos tipos tumorales en correlación con la evolución clínica de los pacientes. IP: Matilde Lleonart Pajarin Study of new genes involved in proliferation Searching for new proliferative genes/tumor suppressor genes is being performed at our laboratory by carring out genetic screens. By the use of retroviral vectors as carriers of a cDNA libraries (formed by mRNA from murine embryonic stem cells), primary cells are infected and screening for those clones able to bypass senescence are selected for further characterization. The marked morphological heterogeneity observed in several tumorigenic process, support the hypothesis that several cancers have their origin in a stem cell. It is believed that genes expressed by embryonic stem cells, may play an important role in the tumorigenic mechanism.This project unravels the effect of immortal genes existing in embryonic stem cells, when are forced to be expressed in primary and thereby mortal cells. These immortal genes are future candidate markers in tumors with potential prognosis value. The novel genes discovered, are being analyzed in the biopsies from patients with different kinds of tumors collected at the Pathology Department of the Vall d´Hebrón Hospital.
