Brief description of the research:

Combing pathology and molecular biology, the aim of our group is to unravel the molecular mechanisms in cancer progression and chemotherapeutic drug resistance. Our research focuses on:

  1. Cellular Stress related to Cancer
    • Validation and characterization of novel Mnk1/2 inhibitors.
    • Characterization of ITGB3 as a potential therapeutic target.
  2. Intra tumor heterogeneity and clonal cooperation
    Taking advantage of having the expertise and availability of primary tumors in the Pathology department and the molecular and cell biological expertise in the research group, we are in a privileged position to study the different aspects of tumor biology at the pathological and molecular level at the same time.
