Abstract

Germ cell tumours (GCTs) are a diverse group of neoplasms that can be histologically subclassified as either seminomatous or non-seminomatous. These two subtypes have distinct levels of differentiation and clinical characteristics, the non-seminomatous tumours being associated with poorer prognosis. In this article, we review how different patterns of aberrant DNA methylation relate to these subtypes. Aberrant DNA methylation is a hallmark of all human cancers, but particular subsets of cancers show unusually high frequencies of promoter region hypermethylation. Such a 'methylator phenotype' has been described in non-seminomatous tumours. We discuss the possible cause of distinct methylation profiles in GCTs and the potential of DNA methylation to provide new targets for therapy. We also consider how recent developments in our understanding of this epigenetic modification and the development of genome-wide technologies are shedding new light on the role of DNA methylation in cancer aetiology. © 2013 Society for Reproduction and Fertility.
