Over the last years the sequencing field has moved quickly and many methods have been developed that use deep-sequencing readouts to assess how the chromatin structure, epigenome and the transcriptome are linked.
Within the Heidelberg Center for Personalized Oncology (DKFZ-HIPO), the CHromatin And RNA Methods (CHARM) lab is dedicated to develop and adapt genome-wide chromatin and RNA methods for primary patient material. Workflows for different tumor entities, such as 3D cell culture, solid tumors and PBMCs, are carefully validated.

At this stage, ChIPseq of histone modifications, MNase-seq (to determine nucleosome positions), detection of accessible chromatin regions and tagmentation-based bisulfite sequencing have already been successfully applied within the HIPO program. A collection of validated antibodies for histone modifications and certain chromatin interacting proteins is available. Next, we plan to add the analysis of spatial genome folding via 3C/Hi-C methods. In addition, as a more long-term goal, we aim to establish and develop single-cell genomics, transcriptomics and epigenomics methods to address tumor heterogeneity.

All sequencing libraries are sequenced at the DKFZ High Throughput Sequencing Unit (GPCF) with subsequent data analysis by the HIPO bioinformatics group.

Our goal is to provide a comprehensive view on the regulation of the cancer genome to foster new strategies for personalized cancer treatment.
