Francis Crick Institute

London, United Kingdom

BRF Genetic Modification Service (GeMS) Senior Research Scientist
Reports to: Head of GeMS

This is a full time, fixed term (3 year) position on Crick terms and conditions of employment.

This project will involve a certain about of time in Oxford, but the role will be predominantly based at the Crick


The MRC National Mouse Genetics Network is a major new £22 million investment in mouse genetics for disease modelling that will capitalise on the UK’s international excellence in the biomedical sciences. The Network is comprised of challenge-led research clusters, with members distributed across the UK.

The Genetic Modification Service Group (GeMS), within the Biological Research Facility (BRF) at the Francis Crick Institute has received funding from the network to explore new technology for modelling large complex alleles in the mouse. Working initially in embryonic stem cells, we will explore site-specific nuclease and recombinase technologies for optimizing the large-scale engineering of the mouse genome. If successful, we will then adapt the protocols to achieve complex allele engineering in the mouse embryo.

Animal models provide an important means to determine gene function and model disease. The Biological Research Facility (BRF) are providing expertise and support for housing and experiment, all underpinned with world-class standards of welfare. Within the BRF, the Genetic Modification Services (GeMS) team provides the specialist skills and resources for the production, storage and use of genetically modified animals & cell lines.

Project summary

Mutations associated with human disease can be engineered into the equivalent genes in mice, and the resulting genetically modified mice provide important insights into disease mechanism, revealing new targets for future medicines. Furthermore, these mouse models of human disease have considerable utility for preclinical testing of new medicines and can help the development of new tools to help disease diagnosis.

To date, most disease mutations that have been explored using mouse models are restricted to mutations which affect the DNA encoding proteins. Investigations into genetic variation in humans over the last decade, however, have revealed that mutations and variation in non-protein-coding DNA sequences and the overall structure of human genes play an important role in defining disease and disease-risk.

Significant differences also exist between mouse and human in these non-coding sequences and overall gene structure. Consequently, more sophisticated modelling of human disease mutations in the mouse is required. This is important both with respect to accurately modelling the human disease in mouse but also for testing new medicines that act on human gene products or new generation therapies that act upon on human primary gene sequences.

We need to develop tools that enable manipulation and assessment of DNA sequences at much larger scale than conventionally performed to allow an accurate investigation and modelling of human disease in mouse.

Methods have been reported by a few research teams around the world, but there is no clear best practice established for engineering the mouse genome in this way. UK researchers are able to access technologies for achieving simple modifications of the genome, through core facilities within their universities or via access to national and international programmes. There is, however, currently no capacity within the UK for the more sophisticated large-scale engineering in the mouse that our understanding of disease biology now demands.

Our project will address this unmet need. We will explore and optimize the different experimental parameters and compare different methodologies. We aim to establish robust pipelines for engineering complete human genes and synthetic segments into the mouse.

The technology and the resulting models will assist in our understanding of disease and the development of new therapies.
