Die Evolution von Hirntumoren

(PresseBox) (Heidelberg, )
Nur drei verschiedene Erbgutveränderungen treiben die frühe Entwicklung bösartiger Glioblastome an, fanden Wissenschaftler vom Deutschen Krebsforschungszentrum in einer aktuellen Untersuchung. Bei allen untersuchten Tumoren lag mindestens einer dieser drei Krebstreiber vor. Doch erst eine Aktivierung der Telomerase sorgt schließlich für rasantes Größenwachstum. Bis zu sieben Jahre entwickeln sich die Glioblastome, bevor sie sich durch Symptome bemerkbar machen und diagnostiziert werden. Doch im Gegensatz zu ihrer frühen Entwicklung teilen Glioblastome, die nach der Therapie zurückkehren, so gut wie keine übereinstimmenden Erbgutveränderungen.
