Gold-Nanopartikel machen den Ursprung des Wachstums von Krebszellen in ganzen Zellen sichtbar

(PresseBox) (Saarbrücken, )
Während sich gesunde Zellen durch Teilung und Absterben erneuern, verläuft die Zellteilung bei Krebszellen ungehemmt, weil ihr natürlicher Zelltod außer Kraft gesetzt ist. Dies geschieht, weil sich zu viele Rezeptoren für den Wachstumsfaktor EGF, die sich auf der Zelloberfläche befinden, zu Pärchen koppeln. Diese Pärchen starten eine Signalkette in die Zelle hinein, an deren Ende das ungebremste Wachstum steht. Nun gelang es Wissenschaftlern am INM - Leibniz-Institut für Neue Materialien erstmals, diese Paarbildung in menschlichen Krebszellen an einzelnen Rezeptoren durch Gold-Nanopartikel sichtbar zu machen. Die Ergebnisse wurde vor Kurzem im Online-Journal Scientific Reports veröffentlicht.
