Despite years of research, there has been little improvement in survival for patients with disseminated melanoma. Recent work has identified mutations in BRAF and NRAS, leading to constitutive mitogen-activated protein kinase (MAPK) pathway as well as constitutive activity in the phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) pathway, as being critical events in melanoma growth and progression. In the current review, we discuss how these complex mutational and signaling profiles can be understood using a network biology approach, and suggest how an understanding of the key signaling nodes involved in progression and survival will lead to improvements in melanoma therapy.
