Inherited macular dystrophies (MDs) are genetically heterogeneous making a single therapeutic approach difficult. Given the limited therapeutic options there is a critical need for additional therapies, especially ones that are widely applicable. The majority of MD mutations result in proteins that are either less active than normal or are expressed at a lower level than normal. These both outcomes result in decreased functionality, leading to disease.
This research project will test whether CRISPR-activation (CRISPRa) can correct or ameliorate the abnormal gene expression and cellular function resulting from mutations in genes that cause MDs. CRISPRa gene transactivation works by recruiting transcription factors to the target promoter. The increased gene expression compensates for mutations that either cause proteins to be less active or for less than normal amounts of protein to be made. CRISPRa has already shown great promise as a therapy for a diverse range of human conditions including an inherited retinal dystrophy (1, 2).
In this project the CRISPRa reagents for each target gene will be optimized in cell lines and transactivation determined by gene and protein expression. Once optimized, the system will be tested in tissue derived from patient induced pluripotent stem cells (iPSCs). In the final stage of the project the functional rescue resulting from CRISPRa will be assessed in retinal tissue.
The supervisory team have extensive experience in all the techniques to be used in this project. Dr Manson has extensive experience in eye genetics and functional genomics and is using CRISPR in retinal organoids to study eye development and function (3). Professor Wang uses patient-specific iPSCs to study the molecular basis of small vessel diseases (4). Dr Adamson is the manager of the faculty’s Genome Editing Unit and has wide experience in the development and use of CRISPR technologies (5).
