Ingenious Genes

A proposal for a new model of the evolution of gene regulation networks and development that draws on work from artificial intelligence and philosophy of mind. Each of us is a collection of more than ten trillion cells, busy performing tasks crucial to our continued existence. Gene regulation networks, consisting of a subset of genes called transcription factors, control cellular activity, producing the right gene activities for the many situations that the multiplicity of cells in our bodies face. Genes working together make up a truly ingenious system. In this book, Roger Sansom investigates how gene regulation works and how such a refined but simple system evolved. Sansom describes in detail two frameworks for understanding gene regulation. The first, developed by the theoretical biologist Stuart Kauffman, holds that gene regulation networks are fundamentally systems that repeat patterns of gene expression. Sansom finds Kauffman's framework an inadequate explanation for how cells overcome the difficulty of development. Sansom proposes an alternative: the connectionist framework. Drawing on work from artificial intelligence and philosophy of mind, he argues that the key lies in how multiple transcription factors combine to regulate a single gene, acting in a way that is qualitatively consistent. This allows the expression of genes to be finely tuned to the variable microenvironments of cells. Because of the nature of both development and its evolution, we can gain insight into the developmental process when we identify gene regulation networks as the controllers of development. The ingenuity of genes is explained by how gene regulation networks evolve to control development.

For over half a century, we have been in the thrall of the double-helicaln structure of DNA, which, in an instant, revealed that information can be transferred between generations by a simple rule, A pairs with T, G pairs with C. In its beautiful simplicity, this structure, along with the table of codons worked out in the following decade, had entranced us into believing that we can fully understand the information content of a DNA sequence, simply by treating it as text that is read in a linear fashion. While we have learned much based on this assumption, there is much we have missed. Far from a passive tape running through a reader, genomes contain information that appears in new forms which create regions with distinct behavior. Some are "gene rich", some mobile, some full of repeats and duplications, some sticking together across long evolutionary distances, some readily breaking apart in tumor cells. Even protein-coding regions can carry additional information, taking advantage of the flexible coding options provided by the degeneracy of the genetic code. The chapters in this volume touch on one or more of three interconnected themes; information can be implied, rather than explicit, in a genome; information can lead to focused and/or regulated changes in nucleotide sequences; information that affects the probability of distinct classes of mutation has implications for evolutionary theory.

The idea of evolving machines, whose origins can be traced to the cybernetics movementofthe1940sand1950s,hasrecentlyresurgedintheformofthenascent ?eld of bio-inspired systems and evolvable hardware. The inaugural workshop, Towards Evolvable Hardware, took place in Lausanne in October 1995, followed by the First International Conference on Evolvable Systems: From Biology to Hardware (ICES), held in Tsukuba, Japan in October 1996. The second ICES conference was held in Lausanne in September 1998, with the third and fourth being held in Edinburgh, April 2000 and Tokyo, October 2001 respectively. This has become the leading conference in the ?eld of evolvable systems and the 2003 conference promised to be at least as good as, if not better than, the four that preceeded it. The ?fth international conference was built on the success of its predec- sors, aiming at presenting the latest developments in the ?eld. In addition, it brought together researchers who use biologically inspired concepts to imp- ment real systems in arti?cial intelligence, arti?cial life, robotics, VLSI design and related domains. We would say that this ?fth conference followed on from the previous four in that it consisted of a number of high-quality interesting thought-provoking papers.

Mobilization and Reassembly of Genetic Information documents the proceedings of the Miami Winter Symposium, sponsored by the Department of Biochemistry, University of Miami School of Medicine, Miami, Florida, January 1977. This volume is the 13th in the ""Miami Winter Symposia"" series. Topics for the Miami Winter Symposia focus on areas of biochemistry in which recent progress offers new insights into the molecular basis of biological phenomena. The manuscripts presented by researchers at the symposium cover a wide range of topics including DNA cloning and plasmid biology; yeast DNA expression in Escherichia coli; characterization of tetracycline and ampicillin resistant plasmid cloning vehicles; eukaryotic genome organization; bacterial plasmids containing silk gene sequences; DNA cloning in bacteria for the study of immunoglobulin genes; DNA degradation by rat intestinal nucleases; recombination between bacterial plasmids leading to the formation of plasmid multimers; general methods for inserting specific DNA sequences in cloning vehicles; and cloning and characterization of yeast DNA.
