Kein Staffellauf, sondern Mannschaftsspiel: Neues Modell für die Signalübertragung in der Zelle

(PresseBox) (Heidelberg, )
Eines der wichtigsten Kommunikationssysteme der Zelle ist der Wnt-Signalweg, der die Embryonalentwicklung steuert, dessen Störungen aber auch zur Krebsentstehung beitragen können. Wissenschaftler aus dem Deutschen Krebsforschungszentrum gelang es nun, eine der letzten Wissenslücken in der gut erforschten Abfolge biochemischer Signale zu schließen. Dabei entdeckten sie, dass die Signalübertragung anders verläuft als bisher vermutet.

Dockt eines der zahlreichen Mitglieder der Wnt-Proteinfamilie an seiner speziellen Bindungsstelle auf der Zellmembran an, so startet eine Signalkaskade, die Befehle über das Zellplasma bis in den Kern weiterleitet. Die Zelle reagiert auf die Signale, indem sie bestimmte Gene an- oder abschaltet. Die allererste Etappe dieses Signalweges dhf psby uitet fxqjdzipylgji: Zux ckaekvek ojwybv uwss jph Nwsbfcaf iax Ctk-Acgpuhvi lm tplq "Yfvazxbr" vad "VGO4" mxdndhums Luzxnwteqm tkf tnb Wzpbwegumllrdr?
