How Does DNA Methylation Relate to Cancer?
DNA methylation is an essential epigenetic mechanism that can regulate gene expression without altering the DNA sequence. In the context of cancer, aberrant DNA methylation patterns, such as hypermethylation of
tumor suppressor genes or hypomethylation of
oncogenes, can lead to uncontrolled cell growth and tumorigenesis. Therefore, studying these patterns could provide insights into
cancer diagnosis, prognosis, and treatment.
