Zusammenfassung der Projektergebnisse
The aim of the project was to investigate which role epigenetic processes play in the development of the nervous system and its diseases. Using a transgenic approach, we intended to analyse the immediate effects of loss of histone modifications through overexpression of histone mutants in mouse neural stem cells. Early in the implementation of the project, we deviated from the original experimental strategy due to emerging publications and budget restraints. Instead, we explored the options novel CRISPR approaches can provide for the investigation of epigenetic processes. In the context of the project, we have developed tools and strategies for epigenome editing and transcriptional engineering in the nervous system, developed tools and strategies for epigenomic screens and for gRNA multiplexing. Furthermore, we have introduced these experimental strategies (e.g. epigenome editing and transcriptional engineering) to a larger scientific audience. In summary, this project provides a solid base for the use of non-genetic CRISPR approaches for the investigation of epigenetic processes during development and disease of the nervous system.
