Since the discovery of oncogenes as well as tumor suppressor genes it has been known that a large factor of causing and repressing cancer is within our own genome. If areas around oncogenes become unmethylated these cancer-causing genes have the potential to be transcribed at an alarming rate. Opposite of this is the methylation of tumor suppressor genes.
Since the identification of oncogenes as well as tumor suppressor genes, it has been recognized that a significant factor in causing and inhibiting cancer is located within our own genome. If regions around oncogenes become demethylated, these cancer-causing genes have the potential to be transcribed at an alarming rate. Conversely, the methylation of tumor suppressor genes.
