Medulloblastome der Gruppe 3 - dem pädiatrischen Gehirntumor mit der ungünstigsten Prognose - werden mit einer Reihe umfangreicherer DNA-Umlagerungen in Verbindung gebracht, die ausnahmslos denselben übergreifenden Effekt auf bestimmte weit voneinander entfernt gelegene Gene haben. Dies fanden Wissenschaftler am Europäischen Institut für Molekularbiologie (EMBL) und dem Deutschen Krebsforschungszentrum (DKFZ), beide in Heidelberg, sowie dem US-amerikanischen Sanford-Burnham Medical Research Institute in San Diego heraus. Die Studie wird heute online in der Fachzeitschrift Nature veröffentlicht.
