Krebs: "Ur-Gen" entdeckt

Forscher weisen Krebsgen in urzeitlichen Vielzellern nach

(PresseBox) (Innsbruck, )
Auf der Suche nach den Ursachen von Krebserkrankungen haben Biochemiker und Entwicklungsbiologen der Universität Innsbruck gemeinsam den Ursprung eines wichtigen menschlichen Krebsgens 600 Millionen Jahre zurückverfolgt. In Süßwasserpolypen konnten sie erstmals das Onkogen myc nachweisen und zeigen, dass es in den urzeitlichen Tieren ähnliche biochemische Eigenschaften wie beim Menschen hat. Die Forscher berichten darüber in der renommierten Fachzeitschrift PNAS.

Das myc-Gen ist entscheidend am Wachstum von Organismen beteiligt. Es erzeugt ein Protein, das als Genregulator die Expression von 15 Prozent aller menschlichen Gene steuert. Das heißt es kontrolliert, ob diese Gene aktiviert oder deaktiviert sind. Ist das myc-Gen verändert, gywj fyy Bjlopbko fzn Hqjefm qomds Vxwnenomp fqbfaom fjf ae futot Hqonjgofrhlfgcz npsgvu.
