Gene Expression Array Analysis to Identify Candidate Tumor Suppressor Genes in Melanoma.

Abstract

Melanoma is a complex multifactorial disease; therefore, a combination of various approaches is necessary to girt all aspects of its biology and identify the many different genes and factors involved in its etiology.Epigenetic regulation of tumor suppressor genes (TSGs) has been shown to play a central role in melanomagenesis. Here, we describe a new pipeline based on an integrative and comparative analysis of several array platform, post-demethylation treatment expression data, methylation array, and constitutive mRNA expression analysis to identify novel TSGs frequently methylated in melanoma.
