Eisen treibt Tumorzellen in den Tod

(PresseBox) (Heidelberg, )
Tumorzellen und gesunde Zellen unterscheiden sich erheblich in ihrer Stoffwechselleistung. Wissenschaftler aus dem Deutschen Krebsforschungszentrum machten sich diesen Unterschied zunutze: Durch die Freisetzung von zellulärem Eisen konnten sie gezielt Tumorzellen in den Tod treiben.

Das schnelle Wachstum von Krebszellen und ihre häufigen Teilungen haben ihren Preis: Krebszellen haben einen deutlich höheren Energiebedarf als gesunde Zellen. Ihr auf Hochtouren laufender Stoffwechsel benötigt große Mengen an Spurenelementen, insbesondere an Eisen. Jedoch führt ein hoher Eisenspiegel in der Zelle zur Produktion von extrem schädlichen freien Radikalen. Um sich davor zu schützen, inaktiviert die Zelle das freie Eisen durch die Bindung an so genannte Ldrvkhmxcgrsjqvgsrmxt.
