Research at the Division of Functional Genome Analysis focuses on the development and immediate application of new technologies for an assessment and description of both the realisation and regulation of cellular function from genetic information.

Analyses of tumour material are at the centre of attention, with an emphasis on pancreatic cancer and personalised approaches. Studies are under way about the effect of DNA sequence variations and the epigenetic modulation of the genome. Measurements are performed on variations in transcription factor binding and changes in transcript levels of coding and non-coding RNAs. Concomitantly, the actual protein expression is analysed, mostly by means of affinity-based assay formats. Beside the creation of knowledge, we aim at the establishment of means for reliable, potentially early and non-invasive diagnosis, accurate prognosis and patient stratification, monitoring of treatment results and the establishment of new therapeutic approaches. Particularly for the last objective, we complement the molecular analyses with functional studies for the elucidation of relevant cellular mechanisms.

A particular focus are developments and applications in the field of affinity-based proteome analysis, since analytical processes in this area are still inadequate for many, in particular biomedical purposes. We have established affinity-based processes that permit analyses with a robustness and reproducibility that meet the requirements of clinical applications. One aim is the identification of disease-relevant protein isoforms, since structural variation is often an immediate indicator for different functional activity. Quantitative measurements of protein interactions are performed, in particular for the identification of variations that occur at a personal level. Another activity is the creation of a map of protein-mediated communication between the different cell types of the tumour microenvironment.

Another line of work aims at the fully synthetic, in vitro implementation of complex biological processes. Motivation is their utilisation for the production of biomedically active molecules, such as non-immunogenic agents, and the establishment of entirely artificial molecular systems. Cell-free biosynthetic production will be crucial for mastering many biotechnological and pharmacochemical challenges. Artificial experimental systems will complement current systems biology by evaluating biological models experimentally. Similar to physics, insight into cellular function will be gained by an iterative processing of information by experimental and theoretical systems biology. Eventually, this may lead to the establishment of a fully synthetic self-replicating system and, ultimately, an archetypical model of a cell.
