Epigenetics discovery could lead to new class of cancer drugs

Drug Discovery World

A new paper has solved the 20-year mystery of how epigenetic modifications act as traffic lights to control gene expression and could ultimately speed up the development of a new class of epigenetic cancer drugs. But, until now, scientists lacked an understanding of what the chemical tag does, despite many years of research.
