Adhesion Signaling and the Tumor Matrix Environment

The extracellular matrix (ECM) and its cellular receptors of the integrin family play a determinant role in tumor development by translating external cues into morphological and behavioural changes.

 

   

Our current investigations aim to identify the molecular mechanisms that underlie this process and to elucidate the function of fibronectin splice variants. Spliced forms of fibronectin ( “oncofetal” FN ) produced by both endothelial cells and certain tumor cells, including invasive glioblastomas, represent a major constituent of the provisional ECM and likely play an important role in capillary morphogenesis, tumor-endothelial cell interactions and recruitment of various host cells to the developing tumor.

In collaboration with the translational and clinical research teams of the Centre A. Lacassagne and the Nice University Hospitals (CHU) we are involved in studies on squamous cell carcinomas of the head and neck (SCCHN). Clearly, aberrant regulation of actin cytoskeleton dynamics contributes to the invasive behavior of these tumors. A major focus of our work addresses the function of cortactin, an actin binding protein encoded by the CTTN/EMS1 gene (frequently amplified in SSCHN and breast tumors).
