摘要

In this keynote presentation, we will provide an introduction to systems biology, an interdisciplinary approach aimed towards a better understanding of the physical basis of life. Biology is a thriving science where exciting new discoveries are made almost on a daily basis. Nevertheless, big achievements like the human genome project do not mark the completion but the beginning of the next level of understanding. Mathematical biology, metabolic engineering and chemical engineering approaches towards the cell or an organism are emerging as the "post-(gen)omic" frontiers. Whereas the "omic"-technologies produce large amounts of data, systems biology is promising to put the pieces back together by integrating knowledge using mathematical descriptions. Exemplary we will introduce the audience to the challenges in the field of systems biology by looking at programmed cell death, also called apoptosis. Apoptosis is a molecular program by which single cells can be eliminated for the benefit of the organism as a whole. It is present in all cells of multi-cellular organisms and crucial during development and for cellular homoeostasis. The topic has attracted more than 100000 related publications in recent years. Its importance is outlined by the fact that in the adult human approximately 10 billion cells die every day to balance those reproduced during mitosis [2]. Too little apoptosis and uncontrolled reproduction are hallmarks of cancer whereas too much apoptosis is implicated in neurodegenerative diseases such as Alzheimer.
