The enemy within: dormant retroviruses awaken

Journal name:
Nature Medicine
Year published:

Mammalian genomes harbor regulatory elements from ancient retroviral infections. These retroviral remnants are normally silenced by DNA methylation—but this can change. Reactivation of one such element triggers the expression of a nearby oncogene during the development of Hodgkin's lymphoma (571–579).
