"Wächter des Genoms" wird das Molekül p53 genannt, weil es unkontrolliert wuchernden Zellen - und damit dem Krebs - Einhalt gebieten kann. Doch dieser wichtige Schutzfaktor hat auch dunkle Seiten, wie Prof. Martin Hrabé de Angelis, Direktor des Instituts für Experimentelle Genetik des Helmholtz Zentrums München, und Dr. Helmut Fuchs, der wissenschaftlich-technische Leiter der German Mouse Clinic, nun im Rahmen einer internationalen Studie zeigen konnten. Denn p53 reagiert auch auf bestimmte Defekte in den Proteinfabriken der Zelle, den Ribosomen, und kann dann bei Mensch und Tier verschiedene Störungen verursachen.
