Discovery of novel hypermethylated genes in prostate cancer using genomic CpG island microarrays.
<h4>Background</h4>Promoter and 5' end methylation regulation of tumour suppressor genes is a common feature of many cancers. Such occurrences often lead to the silencing of these key genes and thus they may contribute to the development of cancer, including prostate cancer.<h4&g...
