Abstract:
DNA methylation plays an important role in the regulation of gene expression. Tumor cells are characterized by alterations of DNA methylation pattern, namely local CpG island hypermethylation and genome wide hypomethylation. The hypomethylation of the genome affects many repetitive sequences and transposable elements and is believed to results in chromosomal instability and increased mutations events. In this review we summarize the current knowledge concerning epigenetic mechanisms related to cancer, especially the relationship of DNA hypomethylation to carcinogenesis.

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
