Abstract

Over the past two decades, several known genes have been shown to govern important functions in the development of primary and metastatic melanomas. However, from this limited number of genes, it is not possible to establish detailed molecular profiles for the early and advanced stages of melanoma development. To gain insights into the genetic profile of every stage of the melanoma progression pathway, and to determine to what extent these profiles are similar or distinct, we performed whole-genome expression profiling of tissue specimens representing normal skin, benign and atypical nevi, and early and advanced-stage melanomas. The results of this study provide first-time evidence that significant molecular changes occur distinctly at the border of/transition from melanoma in situ to primary melanoma, and that genes involved in mitotic cell cycle regulation and cell proliferation constitute the two leading categories of genes associated with these changes.
