Fast Facts: 1  Alterations to chemicals attached to DNA, known as epigenetic changes, affect how genes do their work and have been linked to colon cancer. 2  A new study of six different cancer types found distinctive epigenetic changes in all of them.These insights into the cancer epigenome could provide a foundation for development of early screening or preventive treatment for cancer,â Timp says, suggesting that the distinctive methylation âfingerprintâ could potentially be used to tell early-stage cancers apart from other, harmless growths.
Cancer initiation and progression are accompanied by profound changes in DNA methylation that were the first epigenetic alterations identified in cancer (67, 68). A cancer epigenome is marked by genome-wide hypomethylation and site-specific CpG island promoter hypermethylation (Figure 2) (3).bstract. Epigenetic mechanisms are essential for normal development and maintenance of tissue-specific gene expression patterns in mammals. Disruption of epigenetic processes can lead to altered gene function and malignant cellular transformation. Global changes in the epigenetic landscape are a hallmark of cancer.
