Rho GTPases • cell migration • signal transduction • neuronal development • breast cancer

Research Focus

My research focuses on the signaling pathways mediated by the Rho family of small GTPases. Rho GTPases play a critical role in many aspects of cell biology, in cell migration, cell adhesion, cell morphology and cell growth. These cellular events are crucial for the normal development and physiology in humans. For instance, in the adult, migration events are involved in the normal physiology as well as in pathology such as metastasis. In embryogenesis, cell migration is an important feature of the development of the nervous system. Using molecular and cellular approaches, we are interested to delineate the role of Rho GTPases in cell migration, in particular, in neuronal development and in the cellular processes leading to cancer metastasis. Understanding the molecular mechanisms underlying the Rho proteins in cell migration and cell adhesion will be helpful to identify novel drug targets for tumor therapy and neurodegenerative diseases.
