MicroRNA schaltet Tumorschutz aus

(PresseBox) (Heidelberg, )
Die MicroRNA miR-21 unterdrückt die Herstellung des Tumorsuppressors Pdcd4, der Zellen vor der Krebsentwicklung schützt. Pdcd4 fehlt besonders in Darmkrebszellen, wie Forscher im DKFZ jetzt herausfanden. Dagegen ist miR-21 in diesen Zellen übermäßig vorhanden und fördert die Ausbreitung bösartiger Tumoren im Darm.

Die Entdeckung der MicroRNAs liegt noch nicht lange zurück. Erst seit einigen Jahren weiß man, wie die kleinen Moleküle - kurze Abschriften der Erbsubstanz DNA - das Leben in einer Zelle mitbestimmen: Sie heften sich an andere DNA-Abschriften, die zum Aufbau von Proteinen benötigt werden. Durch das Anheften der MicroRNA werden diese Bauanleitungen blockiert oder sogar abgebaut, noch dfjzn bkp itc Mhcgtunsfryfrpnwu nmtciitet jlyntn ebnozd.
