Den Lebensnerv des Tumors treffen

Schweizerisch-Finnisches Forschungsteam klärt Struktur einer wichtigen Ansatzstelle für Krebsmedikamente

(PresseBox) (Villigen PSI, )
Um wachsen zu können, muss ein Krebstumor von Blut- und Lymphgefässen durchzogen sein, die ihn mit Sauerstoff und Nährstoffen versorgen und durch die der in der Zelle entstehende Abfall entsorgt werden kann. Um sich diese Versorgung zu sichern, senden Tumore Botenstoffe aus, die umliegende Gefässe veranlassen, sich zu verzweigen und in den Tumor hineinzuwachsen. Einen wichtigen Schritt zum besseren Verständnis der molekularen Vorgänge bei der Gefässbildung in Tumoren haben nun Forschende des Paul Scherrer Instituts und des Biomedicum in Helsinki, Finnland gemacht. Sie haben die Struktur der Bindungsstelle aufgeklärt, an der sich ein Botenstoffmolekül mit dem entsprechenden Rezeptor auf der Athndulxqzifap dmbxkzoky.
