Final Report Abstract

Signaling networks control key decisions during development of organisms and are often mutated in cancer. We made use of recent technological advancements to systematically investigate signaling pathways. Next generation sequencing approaches was primarily used for transcriptome profiling to dissect the changes in transcriptional patterns after perturbing signaling pathway components. The next generation sequencer was primarily used in three large-scale projects: (1) we generated several hundred transcriptome profiles after perturbing signaling and transcription factors that are implicated in inflammatory and apoptotic pathways with the goal to understand how different signaling branches determine the transcriptional output in a time-dependent manner. Nested-effect modeling was used to establish models of pathway topology. (2) We analyzed the transcriptional effects of Wnt signaling pathways after stimulation with ligands and depletion of downstream pathway components, and (3) we used sequencing for a de novo assembly of the transcriptome of the planarian Schmidtea mediterranea. In addition, we established workflows to generate multiplexed RNAseq libraries in a semi-automated manner.
