WebJan 22, 2013 · DNA hypermethylation of CpG islands and the polycomb repressive complex. In addition to global DNA hypomethylation, focal DNA hypermethylation at CpG islands is also typical in human cancers , , and is believed to contribute to the reduction of gene expression, especially at tumor suppressor genes. Analysis of gene expression … WebCancer is characterised by DNA hypermethylation and gene silencing of CpG island-associated promoters, including tumour-suppressor genes. The methyl-CpG-binding domain (MBD) family of proteins bind to methylated DNA and can aid in the mediation of gene silencing through interaction with histone deacetylases and histone methyltransferases.
