CpG island hypermethylation is a phenomenon that is important for the regulation of gene expression in cancer cells, as an epigenetic control aberration responsible for gene inactivation. Hypermethylation of CpG islands has been described in almost every type of tumor. Many important cellular pathways, such as DNA repair (hMLH1, for example), cell cycle (p14ARF), apoptosis (DAPK), and cell adherence (CDH1, CDH13), are inactivated by it.
