Aberrant changes of epigenetic landscapes in cancers contribute to the malignant phenotype. Thus, targeting epigenetic pathways are promising therapeutic concepts. In strong support, we have recently demonstrated that class I HDACs are overexpressed in significant fractions of PDAC patients and that therapies based on HDAC inhibitors (HDACi) revealed outstanding efficacy in pre-clinical models. Here we want to follow two leads in order to refine epigenetic therapies.
Firstly, we will define HDAC1, 2, 3 isoenzyme specific functions using novel genetic models. In combination with pharmacological screens we aim for developing novel HDACi-based combination therapies.
Secondly, we want to identify essential PDAC driver genes based on a specific epigenetic signature (super-enhancers). Mechanisms leading to forced expression of these driver genes will be identified through mapping of open chromatin regions within the super enhancers.
The ultimate goal is to translate key findings into therapeutic concepts to be tested in up-to-date human disease models.
