Krebsforscher des Max-Delbrück-Centrums für Molekulare Medizin (MDC) Berlin-Buch haben einen molekularen Mechanismus entdeckt, der das Fortschreiten einer bestimmten Form von Blutkrebs, der chronisch myeloischen Leukämie (CML), bewirkt und Medikamente unwirksam macht. Dr. Marina Scheller (jetzt Universitätskrankenhaus Hamburg-Eppendorf) und Prof. Achim Leutz erbrachten den Nachweis, dass diese beiden Prozesse bei der CML - Verschlechterung der Krankheit und Unwirksamkeit von Medikamenten - direkt zusammenhängen, da sich zwei zelluläre Signalwege in die Quere kommen. Ihre Erkenntnisse bieten neue Konzepte für die Entwicklung von Kombinationstherapien gegen die gefürchtete Progression der Erkrankung (Journal of Experimental Medicine, doi:10.1084/jem.20130706)*.
