Oncogenes in melanoma

Abstract

Transformation of normal melanocytes into melanoma cells is accomplished by the activation of growth stimulatory pathways, typically leading to cellular proliferation, and the inactivation of apoptotic and tumor suppressor pathways. Small molecule inhibitors of proteins in the growth stimulatory pathways are under active investigation, and their application to melanoma patients would represent a new treatement strategy to inhibit cell proliferation or induce cell death. We provide a general overview of the mechanisms of oncogene activation and the functions of oncogenes. Lastly, we review oncogenic events in melanoma.
