Focus of research

Tumor hypoxia is a hallmark of solid tumor development and an adverse prognostic factor as it promotes metastasis, as well as resistance to radio- and chemotherapy, and importantly also to immunotherapy. Tumor hypoxia, resulting from an instable and malfunctioning tumor vasculature, induces resistance to immunotherapy by promoting the formation of an immune suppressive tumor micro-environment. Recently we identified the hypoxia-induced HIF1-E2F7 transcription complex, involved in the regulation of tumor development and angiogenesis, and we are currently exploring if the hypoxia-induced immune suppressive tumor environment can by targeted through this novel complex.
