Research

For many years, we have been cooperating with partners at the Thoraxklinik Heidelberg, working on different molecular alterations and clinical translation in lung cancer (NSCLC). This has enabled us to obtain sustainable funding in the German Center for Lung Diseases (DZL), which provides a secure basis for our future translational lung cancer research. In cooperation with the Thoraxklinik, the Pathology Department Heidelberg and the Weizmann Institute of Science (Israel), we investigated the mutational and epigenomic heterogeneity of NSCLC.

Recent efforts investigating tumor heterogeneity and its influence on resistance to tyrosine kinase inhibitors (TKI) focussed on the establishment and application of 3D coculture models (spheroids of ALK-fusion-positive tumor cells with cancer associated fibroblasts (CAFs)). Using a combination of scRNA-seq, epigenomics, MS-based proteomics and metabolomics technologies, we identified several novel ligand-receptor interactions between CAFs and tumor cells.

We have augmented and extended our liquid biopsy approaches towards the establishment and application of liquid biopsy technologies for tumor monitoring and detection of minimal residual disease (MRD). To this end, we used ca. 500 longitudinal plasma samples from ALK-fusion-positive lung cancer patients (cooperation with the Thoraxklinik Heidelberg) as a proof of principle study to:

• determine single nucleotide variants (SNVs) and copy number variants in plasma DNA,
• correlate molecular data with clinical parameters like oligoprogression ,
• show that the molecular lead time to progression under therapy is shorter compared to radiological lead time,
• identify epigenomic variants to detection tumor progression and MRD.

Our genomics expertise is utilized in cooperative projects aiming at the analysis of genes and biological processes in diverse diseases. In the framework of the International Cancer Genome Consortium (ICGC), we have contributed to the molecular risk classification of tumors (prostate, lung, and PCAWG) using (epi) genomic and transcriptomic characterization of tissue samples. We have contributed to the characterization of spatial and molecular heterogeneity of renal cell cancers, to the investigation of viral sequences in cancer genomes, and to the identification of the receptor for Hepatitis B viruses entering mammalian cells.
