Cancer has become one of the most dangerous diseases of the aging population of industrialized countries. Finding tools to fight cancer is hard, because Cancer presents itself as highly heterogeneous, with over 100 types of cancers described. Not only does Cancer affect aged humans, it has been observed in children in the form of e.g. Medulloblastoma. In the third episode of Active Motif's Epigenetics Podcast, our host Dr. Stefan Dillinger sits down with Dr. David Jones, group leader at the German Cancer Research Center in Heidelberg, to talk about his research on Medulloblastoma and also the emerging role of epigenetic factors in Cancer.
