Final Report Abstract

Ribonucleic acid (RNA) has been known at least since its global use as a vaccine against Covid-19. The rapid availability of the vaccine is based on RNA modifications, small changes in RNA introduced by enzymes, which fulfil a variety of biological functions. As part of my Emmy Noether project, I investigated natural RNA modifications (epitranscriptome) in humans that are associated with neurological diseases. At the project start I developed mass spectrometry-based methods to determine the physiological quantities of RNA modifications and to make their dynamics measurable. Together with my team, I investigated the enzymes that incorporate modifications into tRNA in healthy humans and are simultaneously absent in patients with neurological hereditary diseases. Together with international partners, we not only succeeded in demonstrating the lack of tRNA modification but also in better understanding the cellular consequences of their absence. Although it has not yet been conclusively clarified, in most cases we have established a connection between the loss of tRNA modification and changes in protein formation. This malformation of the proteins is probably decisive for the disease in patients. In the case of Alzheimer's disease, we were able to show in cell culture that artificially produced but correctly modified tRNA prevents the malformation of protein formation, which represents a first RNA-based therapeutic approach. A total of 19 publications related to the biological context of the Emmy Noether Project were produced, as well as 21 further publications that utilized the technologies and instrument of the project.
