DZNE – Genome Engineering Unit

Mouse models allow basic insights into the development and the progression of neurodegenerative diseases and therefore provide the opportunity to screen for effects of disease triggering genetic factors and of innovative therapeutic approaches in the entire organism. They are required for the solid and rapid preclinical translation of novel knowledge of basic research and the development of therapeutic concepts. Thus, these models are vital for molecular, physiological and behavioral dissection of neurodegenerative diseases. Hence the “Genome Engineering” Unit has the task to generate new, state-of-the-art mouse models for dementia, frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS), respectively to investigate the impact of genetic defects on phenotypes and to evaluate innovative therapeutic approaches.

To generate transgenic mouse models (e.g. point mutations, null mutations, conditional inducible knock-in and knock-out mutants, and deletion mutants), standard methods like the manipulation of mouse embryonic stem cells, the establishment of germ line chimera and the latest genome editing technologies, which includes the application of TALENs and the CRISPR/Cas9 system, directly in mouse one-cell embryos, are used.

The portfolio of the unit encompasses consulting and support in the design of targeting strategies, targeting vector design, the use of ES cells or one-cell embryos, validation of established models, interpretation of results, provision of standard procedures (SOPs), and providing direct access to the EUCOMM/IKMC mouse mutant resources (Prof. Dr. W. Wurst, coordinator). Furthermore, new methods are constantly developed to easily and specifically induce somatic mutations, to improve targeting efficiency, to reduce additional, unintended mutations, and to reduce the number of animals used.

Besides the generation of new transgenic mouse lines, the Unit also provides counseling in mutant analysis in particular of molecular, histological and behavioral studies.
