Abstract
Die Expression von Zytokinen aus Tumor- und Normalgewebszellen spielt bei der Vermittlung der Strahlenwirkung auf Tumoren eine wichtige Rolle. Tumor-Nekrose-Faktor alpha (TNF α), ein pleiotropes, primär als Monokin beschriebenes Polypeptid, ist durch seine zytotoxische Wirkung auf Tumorzellen sowie durch die Induktion hämorrhagischer Nekrosen von Tumoren von besonderem Interesse. Die vorliegende Arbeit untersucht den Einfluß ionisierender Strahlen auf die tumorzelleigene Expression von TNF α an einer humanen Ewing-Sarkom-Zellinie in vitro und in vivo am Xenograft-Tumor der Nacktmaus.Keywords
