Spuren der Unsterblichkeit im Tumorerbgut

(PresseBox) (Heidelberg, )
Krebszellen sind für ihre Unsterblichkeit darauf angewiesen, ihre als „Telomere“ bezeichneten Chromosomenenden zu erhalten. Dies erreichen sie auf verschiedene Weise. Durch welche Veränderungen im Erbgut sich diese Mechanismen bemerkbar machen, untersuchten Wissenschaftler aus dem Deutschen Krebsforschungszentrum systematisch in über 2500 Tumorgenomen von 36 verschiedenen Krebsarten. Die aktive Verlängerung der Telomere ist eine Achillesferse aller Krebszellen und damit ein wichtiger Ansatzpunkt für die Entwicklung gezielter Therapien. Die Arbeit ist Teil der „Pan-Cancer Analysis of Whole Genomes“ (PCAWG).

Gesunde Körperzellen haben ein natürliches Verfallsdatum, das durch die Länge ihrer Telomere definiert ist. Die Telomere sind Bestandteile der DNA und schützen die Enden grw Rnpeghnfepf.
