Lately the field of epigenetics has been rapidly changing and progressing. Advances that were made possible because of the Human Genome Project have opened up new possibilities about how epigenetics can be used to stop cancer. Scientists have recently discovered that there are potentially two sets of enzymes that are responsible for regulating the chemical structure of chromatin, which consists of the methyl and acetyl marks in the chromatin structure. Theoretically, by changing and controlling the chromatin structure, scientists can attempt to gain epigenetic control of DNA in order to potentially stop aberrant gene expression.
