Die Herstellung von Boten-RNA (messenger RNA, kurz: mRNA) ist ein wichtiger Schritt in der Herstellung von Proteinen in einer Zelle. In Form von mRNA werden Informationen von Genabschnitten der DNA an das Ribosom weitergereicht, wo die Eiweiße produziert werden. Doch auch der Abbau von mRNA ist von großer Wichtigkeit bei verschiedenen krankheitsrelevanten Prozessen, wie z.B. Entzündungsreaktionen des Körpers. Aufgrund ihrer Komplexität ist das Untersuchen von mRNA-Abbauwegen jedoch sehr anspruchsvoll. Forschern und Forscherinnen des Instituts für Genetik an der Universität zu Köln unter Leitung von PD Dr. Niels Gehring ist es nun gelungen, eine Methode zu erfinden, durch die der Abbau wxz vVVT qb Tsnxviy rbqdbzzp nfbpxpstx dsnrbzkjjc ljwwjc gkxo.
