Dr. Siegfried Neumann-hg: WTEC_Demo_ ppt 1 A German Initiative on Systems Biology of Human Hepatocytes Systems of Life - Systems Biology Presentation to the WTEC delegation by Gisela Miczka, Roland Eils, and Siegfried Neumann Heidelberg, July 7 th, 2004

Dr. Siegfried Neumann-hg: WTEC_Demo_ ppt : How to establish a BMBF funded national research network on Systems Biology Start of the „design-process“: Discussion forum with a multidisciplinary team of 9 leading scientists to develop a funding strategy. The key criteria are  medium to long term research programme  synergy with existing BMBF funded research programmes in Genomics and Proteomics  Considers the international status of the art  reckognizes international standards and contributes to them

Dr. Siegfried Neumann-hg: WTEC_Demo_ ppt 4 Goal of the Systems Biology Initiative on Hepatocytes The long-term goal of this systems biology approach is to understand the dynamic processes in a human cell and to build up mechanism-based mathematical models of these processes in order to predict the behaviour of the system under defined conditions.

Dr. Siegfried Neumann-hg: WTEC_Demo_ ppt 5 Why Hepatocytes? Attractivity central functions in metabolism (for lipids, carbohydrates, amino acids …) central role in the uptake and conversion of drugs (transport, metabolic conversions, detoxification...) ability of regeneration I. e. high impact on problems in pharmacology and pathophysiology

Dr. Siegfried Neumann-hg: WTEC_Demo_ ppt 6 Challenges high complexity of mammalian cells human diffentiated cells are not easy to handle and not easy to cultivate while keeping properties simular to in vivo living cells the mathematical tools for modelling of cellular dynamics and systems analysis basically are not developed for complex systems Aim to overcome the obstacles in order to do systems biology on a medically relevant cell type. !

Dr. Siegfried Neumann-hg: WTEC_Demo_ ppt 7 The Approach set up an interdisciplinary competence network linking bioscience with computer science, mathematics and engineering sciences Start with studies on defined biological functions establish standardized cells, methods, and tools
