Research summary

The majority of adults in the world are infected by Epstein-Barr virus (EBV). Following a primary infection during childhood or adolescence, EBV remains latent in our B-lymphocytes for the rest of our lives.

For most of us this latent infection will go unnoticed. But for approximately 200,000 patients world-wide each year EBV-infection turns into a fatal disease in the form of hematological (post-transplantation lymphoproliferative disease, Hodgkin’s lymphoma and Burkitt’s lymphoma) and epithelial malignancies (gastric adenocarcinoma and nasopharyngeal carcinoma). However, no specific treatment is currently available for EBV-associated malignancies.

We have shown that EBV-associated gastric adenocarcinomas only express a single EBV-gene, RPMS1. RPMS1 encodes a 4 kilobase-pair long non-coding RNA and the same expression pattern can be seen in other EBV-associated malignancies. Interestingly, despite being one of few putative targets for EBV-associated malignancies, this transcript has been completely neglected and the function is not yet known.

Research tools and resources

Our projects encompass clinical and molecular studies of the EBV-associated malignancies with particular focus on mutational landscapes and viral gene expression. We use clinical samples from pre-malignant and malignant stages and analyse them using standard clinical assays and genetic manipulation techniques to affirm potential targets as clinically significant markers and important factors for proliferation.
