Several epigenetic changes are frequently associated with cancer:
DNA Methylation: The addition of a methyl group to the DNA, typically at cytosine bases. Abnormal methylation patterns can silence tumor suppressor genes. Histone Modification: Chemical changes to histone proteins around which DNA is wrapped. These modifications can alter chromatin structure and gene expression. Non-Coding RNA: Molecules like microRNAs can regulate gene expression post-transcriptionally and are often dysregulated in cancer.
