All of these factors can impact methylation patterns. Drugs such as chemotherapy drugs can directly affect DNA methylation. Exercise has been shown to alter DNA methylation patterns in skeletal muscle. Stress can lead to changes in DNA methylation, particularly in genes related to the stress response. Diet can also impact methylation patterns through the intake of certain nutrients and compounds such as folate, vitamin B12, and phytochemicals.
