Our group focuses on preclinical models of pancreatic cancer to test therapy response ex vivo and facilitate personalized patient treatment. Underlying molecular mechanisms of treatment resistance in pancreatic cancer are poorly understood. There has been emerging evidence over the last few years that intratumoral heterogeneity (ITH) is a key determinant in tumor biology, treatment response and ultimately patient survival. Our group aims to establish clone-specific transcriptomic and proteomic profiles associated with distinct treatment response using classical cell line models.
Most currently used preclinical models such as cell lines and xenografts lack the specific tumor microenvironment and therefore allow only limited response prediction. Thus, our group also focuses on organotypic slice cultures which comprise an intact multicellular tissue composition. These cultures can be used rapidly to test for their respective response to drugs in a multicellular, heterogenous environment ex vivo and subsequent downstream analyses such as profiling of the transcriptome and proteome.
