Traditional Chinese Medicine: A Class of Potentially Reliable Epigenetic Drugs.

Epigenetic modification, especially DNA methylation, plays a nonnegligible role in the occurrence and development of tumors. Increasing studies are indicating that traditional Chinese medicine (TCM) plays a considerable anti-tumor role by regulating the process of DNA methylation modification. Studies on TCM regulating DNA methylation modification mostly focus on the whole genome and abnormal methylation status by active ingredients or single compounds and Chinese herb formula (CHF).

6'-O-Galloylpaeoniflorin Exerts Inhibitory Bioactivities in Human Neuroblastoma Cells via Modulating AMPK/miR-489/XIAP Pathway.
