Scientific summary

Melanoma is a highly metastatic neural-crest derived skin cancer. We recently demonstrated the major roles of EMT-inducing transcription factors in the development of malignant melanoma, with TWIST1 and ZEB1 acting as oncogenes whilst SNAIL2 and ZEB2 rather exhibit tumor suppressive function (Caramel et al. Cancer Cell, 2013). A switch from SNAIL2/ZEB2 to ZEB1/TWIST1 expression pattern, directly regulated by the MAPK-dependent AP-1 family member FRA1, is determinant for BRAFV600-driven neoplastic transformation of melanocytes and represents a novel independent predictive factor of poor prognosis in patients with malignant melanoma. The role of EMT-mediated melanoma cell plasticity in the resistance to BRAFV600-targeted therapy is now investigated.

In close collaboration with Stéphane Dalle (dermatology unit, Hôpital Lyon Sud), we are developping both fundamental and translational projects aiming at characterizing new pathways regulating melanoma development and resistance to treatment (MAPK inhibitors and immunotherapy) with the general aim of designing new combination therapies in metastatic melanoma.
