Dr Freek van Eeden
Dr van Eeden has worked in the area of disease modeling in zebrafish for the last 17 years. He participated in a pioneering genetic screen that established the zebrafish as a vertebrate model for development and disease, and he has been contributing to development of the zebrafish system ever since. A main interest in the lab is to understand Von Hippel Lindau disease. This disease leads to formation of a variety of tumours in human patients but the precise reason for this is still poorly understood. His lab has modelled this disease in zebrafish by creating knockouts in both orthologs of VHL in fish. These genes, named vhl and vhl-like, appear to have diversified their function; vhl being a dominant regulator of hypoxia inducible factor. vhl-like, surprisingly, has a function in DNA repair. The latter function was discovered to due to the fortuitous establishment of an in vivo GFP reporter system for genome stability. Use of this reporter system has allowed his lab to define a complex, and dual role of the vhl-type genes in DNA repair. In order to place these DNA repair defects with respect to the known pathways and to study potential interactions, we have used CRISPR to create a collection of mutants with defects in DNA repair including brca2, rad52, rad51 and others. Furthermore, we are developing protocols to damage DNA in various ways and developing analysis methods. We envisage that the use of embryos rather than cell lines, which are often tumor derived or culture adapted, may help to compare and define the roles of these genes. We are collaborating with Dr El-Khamisy and Bryant on this project. In addition, in collaboration with Dr El-Khamisy we have helped to develop a zebrafish CRISPR model for SCAN1 and AT, two neurodegenerative diseases caused by defective DNA repair. Altogether, we are creating an extremely powerful, genetically amenable model system for in vivo analysis of DNA repair and their links with tumourigenesis, neurodegeneration, and aging.
