Eine Veränderung im Gen für das Protein p53, dem "Wächter des Genoms", führt zu einer geradezu explosionsartigen Umlagerung großer Teile des Erbguts von Krebszellen. Heidelberger Wissenschaftler aus dem Deutschen Krebsforschungszentrum (DKFZ) und dem European Molecular Biology Laboratory (EMBL) entdeckten dies an einer besonders aggressiven Gruppe von Hirntumoren bei Kindern. Die Chromosomen-Explosion lässt Zellen offenbar besonders leicht zu Krebs entarten. Diese Ergebnisse veröffentlichten die Forscher in der neuesten Ausgabe der Zeitschrift "Cell".
Menschen mit ererbten Defekten im Gen für das Protein p53 durchleben oft eine jahrzehntelange Leidensgeschichte: Häufig erkranken sie im Laufe ihres Lebens an mehreren verschiedenen Krebsarten.
