Course abstract:<br>
What do Facebook, the human brain, the electricity grid and transcriptional regulation in the cell have in common? One simple answer is that they can all be represented as networks. In fact, studying the structures and features of these networks can help us understand the principles of all of these complex systems. Although networks from entirely different domains share surprising similarities, biological networks also have their own unique characteristics. Analysis of these networks involves using established techniques from statistics, physics and computer science as well as methods developed specifically for studying systems biology. In this course we will introduce biological networks and how they are studied in the context of general network theory. In addition, we will discover how network-based approaches are advancing various areas of biomedical research. We will begin by presenting the basic principles of network structures. We will then cover many of the basic molecular interaction networks studied in biology, including those of protein-protein interactions, transcriptional regulation, microRNA targeting, genetic interactions, drug-target interactions and others. We will see how these networks are constructed from data, what kinds of models are used to study them and what such models can teach us about the organizational principles of biological systems. Furthermore, we will discuss specific questions that can be answered by understanding networks: what is the best way to perturb a biological network to escape from a disease? what does the position of a gene in a network tell us about its function? how can we use networks to identify drugs that share a mode of action? The course will not require any expert knowledge in biology, computer science or statistics and is open to students from any relevant department.<br>
