Cell Biology of Genome Maintenance

Chromosome translocations play key roles in the initiation of tumorigenesis, yet how translocations form is only poorly understood. The goal of our research is to identify cellular and molecular mechanisms underlying the formation of oncogenic chromosome translocations. To achieve this we employ molecular and cell biological approaches (incl. CRISPR/Cas9 technology), in combination with genetics and advanced microscopy techniques.

Using novel imaging methodologies we have developed, we are modelling and quantifying the formation of recurrent, cancer-initiating chromosome translocations in living cells in real time. This will allow us to perform targeted and unbiased screens to identify novel factors that suppress or promote translocations in cancer.
