Testicular germ cell tumour (TGCT) is the most common type of cancer among young men (15 to 45 years of age).
Overall, this imply that ES cells can be considered the non-malignant counterpart of EC cells, providing the rare situation where the "normal" counterpart of a cancer cell with stemness properties is readily accessible, and can be observed through its progression to the malignant state.
By comparing gene expression of EC and ES cells across the genome at high resolution, we aim to gain insight into the role of stem cells in the development and progression of TGCTs, in particular, and cancer in general.
The research project is run jointly between the Molecular Genetics Group and the Genome Biology Group. We have published review articles about the TGCT genome, TGCT epigenome, as well as the TGCT transcriptome.
