Der Abbau von Ribonukleinsäure (RNA, von engl. ribonucleic acid) ist ein wichtiger Mechanismus, um die Genexpression, also die Umsetzung genetischer Informationen, als Reaktion auf Umweltbelastungen zu steuern. Forschende vom Helmholtz-Institut für RNA-basierte Infektionsforschung (HIRI) und der Julius-Maximilians-Universität Würzburg (JMU) haben einen statistischen Ansatz entwickelt, mit dem sich die Halbwertszeiten von RNAs in Bakterien genauer als bisher vorhersagen lassen. Mit der neuen Methode konnte das Team feststellen, dass die RNA-Halbwertszeit in Salmonellen dreimal kürzer ist als bisher angenommen. Außerdem konnten sie die Rolle von RNA-bindenden Proteinen beim RNA-Abbau näher beleuchten. Die Ergebnisse sind in der Fachzeitschrift PNAS erschienen.
