Thèmes de recherche

Our group focuses on the molecular mechanisms and the biological implications of signaling pathway activation in cancer. The evolution of multicellular organisms has involved the development of intercellular communication required for processes such as embryonic development, tissue differentiation, and systemic responses to wounds and infections. These complex signaling networks are in large part mediated by growth factors, cytokines and hormones. In normal conditions, such factors can influence cell proliferation in positive or negative ways, as well as induce a series of differentiated responses in appropriate target cells. Present knowledge indicates that the constitutive activation of signaling pathways through different mechanisms contributes to the development and progression of most if not all human cancers. Major Projects: 1) Based on CRISPR/Cas9 technology, we have recently devised a new approach to recapitulate cancer evolution through the emergence of new mutations in a context of intratumor heterogeneity. Among the different potential applications, this strategy, which we named CRISPR-barcoding, can be implemented to model multiple mechanisms of drug resistance or to repair oncogenic driver mutations in addicted cancer cells. We are currently using CRISPR-barcoding and other more conventional approaches to devise new therapeutic strategies to prevent non-small cell lung cancer resistance to EGFR inhibitors. 2) We investigate the role of canonical and noncanonical Wnt signaling and ROR1/2 receptors in two types of neuroendocrine tumors derived from the sympathoadrenal lineage: neuroblastoma and pheochromocytoma/paraganglioma.
