Abstract: Melanoma is a malignant proliferative disease originated in melanocytes, characterized by high metastatic activity and by the activation of oncogenes, such as B-RAF (40-60% of cases). Recent studies have shown that vemurafenib (a MAPK inhibitor) promoted disturbance of mitochondrial bioenergetics, although underlying mechanisms are not fully comprehended. Here we showed that MAPK inhibition by vemurafenib in B-RAFV600E-mutated human melanoma culminated in the inhibition of DRP1 phosphorylation, associated to a large mitochondrial network remodeling to the hyperfused phenotype, and increased oxidative phosphorylation capacity. Such alterations may be associated to melanoma resistance to vemurafenib, since the impairment of oxidative phosphorylation increased the vemurafenib cytotoxicity. These results point to the potential of mitochondrial dynamics as a targetable pathway in melanoma. • Keywords: B-RAF mutation, MAPK signaling. Melanoma. Mitochondrial Dynamics.
