Melanoma is one of the most lethal cancers when it reaches a metastatic stage Despite advancements in targeted therapies (BRAF inhibitors) or immunotherapies (anti CTLA 4 or anti PD1), most patients with melanoma will need additional treatment Thus, there is an urgent need to develop new therapeutical approaches to bypass resistance and achieve more prolonged responses In this context, we were interested in E2F1, a transcription factor that plays a major role in the control of cell cycle under physiological and pathological conditions Here we confirmed that E2F1 is highly expressed in melanoma cells Inhibition of E2F1 activity further increased melanoma cell death and senescence, both in vitro and in vivo Moreover, blocking E2F1 also induced death of melanoma cells resistant to BRAF inhibitors In conclusion, our studies suggest that targeting the E2F1 signaling pathway may be therapeutically relevant for melanoma.
