1Course Introduction

Model networks involved in signaling - Signals that start outside of the cell (role of the ECM) and trigger cascades inside the cell, ultimately affecting gene expression

Hunter, Peter J., and Thomas K. Borg. "Integration from Proteins to Organs: The Physiome Project." Nature Reviews 4 (March 2003): 237-243.

Kitano, Hiroaki. "Systems Biology: A Brief Overview." Science 295 (March 1, 2002): 1662-1664.
2Information flow in the reverse direction - from DNA to RNA to protein (the central dogma)

Review of regulatory circuits and introduction to the concept of evolutionary genomics

Key Issues: DNA replication and repair errors lead to mutations. Loss of mismatch repair leads to a hyper-Rec phenotype, which facilitates horizontal gene transfer (antibiotic resistance, etc.)

McAdams, Harley H., et al. "The Evolution of Genetic Regulatory Systems in Bacteria." Nature Reviews (Genetics) 5 (March 2004): 1-9.

This paper on evolution of genetic regulatory systems will also introduce the third major topic of the course, chemotaxis; Also read the section on DNA structure and base hydrogen bonding properties from a good biochemistry book.
3Decoding Information I (Transcription Regulation)Denamur, Erick, et al. "Evolutionary Implication of the Frequent Horizontal Transfer of Mismatch Repair Genes." Cell 103 (November 22, 2000): 711-721.

Read as a follow up to the previous paper; this paper shows how the principles in the McAdams paper could be implemented operationally; Also read section on transcription from a good biochemistry book
4Modeling Macromolecular Structure I

Individual Homework Assignments
