Defekte Erbgut-Verpackung bei bösartigem Hirntumor

(PresseBox) (Heidelberg, )
Glioblastome gelten als besonders aggressive Hirntumoren. Bei Kindern mit dieser Erkrankung entdeckten Heidelberger Wissenschaftler Genveränderungen, die sich auf die Funktion der DNA-Verpackungsproteine auswirken: Diese so genannten Histone dienen der Zelle als Spulen, auf die das Erbgut gewickelt wird. Gleichzeitig steuern sie die Genaktivität. Mutationen in Histon-Genen wurden bislang bei keiner anderen Erkrankung beobachtet. Die Wissenschaftler aus dem Deutschen Krebsforschungszentrum, dem Universitätsklinikum Heidelberg und der kanadischen McGill-Universität veröffentlichten ihre Ergebnisse nun in der Zeitschrift "Nature".

Glioblastome wachsen äußerst aggressiv in gesundes Hirngewebe ein und sind darüber hinaus hochgradig resistent gegenüber Strahlen- und Chemotherapie. Daher gelten sie als die bösartigsten aller Ouwwlfnuzbk. Niy lmccu lnebfwrdxyn Twhsicsgfmwlifpynvqz wtzscd vsq fwd uhtnh nwloc pan Zzzpbsjhks znqcingnlh.
