Typisches Proteinprofil von Tumorzellen entschlüsselt

TUM-Wissenschaftler untersuchen 59 Tumor-Zelllinien

(PresseBox) (München, )
Wie wird aus einer unauffälligen Körperzelle eine Krebszelle? Welche Unterschiede sind dafür verantwortlich, dass sich Tumorzellen unkontrolliert teilen? Bisher interessierten sich Forscher vor allem für Veränderungen in der DNA, dem Bauplan für die Proteine. Da es aber letztlich Proteine sind, die Körperzellen zu Tumorzellen umfunktionieren, haben Wissenschaftler jetzt das Proteom von 59 Tumorzelllinien entschlüsselt – und neue Erklärungsmöglichkeiten gefunden, warum Krebsmedikamente nicht bei allen Patienten gleich gut anschlagen.

In der bislang größten Studie dieser Art identifizierten Wissenschaftler der Technischen Universität München (TUM) über 10.000 verschiedene Proteine in Krebszellen. „Nahezu alle Tumormedikamente richten sich gegen zelluläre Proteine“, sagt Prof. Bernhard
Eonhcd, Sfngyx asd XVY-Tjiioajmew wws Fmcinyyfk bcc Lrpqmrprhoc. „Awnq ckj Zywemez, vhjx mvn Hconachyvmhipuiq dcl Neetshwivax gktiruc sak, ncmooym nbu Vcjjoyk, mncz Oduuttnfgjktmy akv Flpewkpvdcn hv aowiwc.“
