Biology as an Informational Science The Practice of Systems Biology A Systems Approach to Disease CHAPTER OUTLINE CHAPTER What is systems biology? Biological system – collection of interacting elements that carry out a specific biological task Can be interacting molecules; . proteins, mRNAs, metabolites, or control elements of genes Can be interacting cells; . immune system cells, hormonal network cells, or neuronal network cells Systems biology – seeks to describe and analyze the complex interactions of components within the system and in relation to components of other systems Requires a cross-disciplinary approach – teams of biologists, computer scientists, chemists, engineers, mathematicians, and physicists Copyright © The McGraw-Hill Companies, Inc. Permission required to reproduce or display Hartwell et al., 4th edition, Chapter 21 Four questions to guide thinking about biological systems What are the elements of the system? Use data sets generated by genomic and proteomic tools What physical associations occur between the elements? . Protein-protein, protein-DNA, cell-cell, etc. What happens when the system is perturbed? Genetic or environmental perturbations What gives rise to a system's emergent properties? Can sometimes be greater than the sum of individual components Copyright © The McGraw-Hill Companies, Inc. Permission required to reproduce or .
