Gene regulatory networks are the most complex, extensive control systems found in nature. The interaction between biology and evolution has been the subject of great interest in recent years. The author, Eric Davidson, has been instrumental in elucidating this relationship. He is a world renowned scientist and a major contributor to the field of developmental biology. The Regulatory Genome beautifully explains the control of animal development in terms of structure/function relations of inherited regulatory DNA sequence, and the emergent properties of the gene regulatory networks composed of these sequences. New insights into the mechanisms of body plan evolution are derived from considerations of the consequences of change in developmental gene regulatory networks. Examples of crucial evidence underscore each major concept. The clear writing style explains regulatory causality without requiring a sophisticated background in descriptive developmental biology. This unique text supersedes anything currently available in the market. The only book in the market that is solely devoted to the genomic regulatory code for animal development Written at a conceptual level, including many novel synthetic concepts that ultimately simplify understanding Presents a comprehensive treatment of molecular control elements that determine the function of genes Provides a comparative treatment of development, based on principles rather than description of developmental processes Considers the evolutionary processes in terms of the structural properties of gene regulatory networks Includes 42 full-color descriptive figures and diagrams

This book serves as an introduction to the myriad computational approaches to gene regulatory modeling and analysis, and is written specifically with experimental biologists in mind. Mathematical jargon is avoided and explanations are given in intuitive terms. In cases where equations are unavoidable, they are derived from first principles or, at the very least, an intuitive description is provided. Extensive examples and a large number of model descriptions are provided for use in both classroom exercises as well as self-guided exploration and learning. As such, the book is ideal for self-learning and also as the basis of a semester-long course for undergraduate and graduate students in molecular biology, bioengineering, genome sciences, or systems biology./a

High-throughput genomics has been increasingly generating the massive amount of genome-wide data. With proper modeling methodologies, we can expect to archive a more comprehensive understanding of the regulatory mechanisms of biological systems. This work presents integrative approaches for the modeling and analysis of gene regulatory systems. In mammals, gene expression regulation is combinatorial in nature, with diverse roles of regulators on target genes. Microarrays (such as Exon Arrays) and RNA-Seq can be used to quantify the whole spectrum of RNA transcripts. ChIP-Seq is being used for the identification of transcription factor (TF) binding sites and histone modification marks. RNA interference (RNAi), coupled with gene expression profiles, allow perturbations of gene regulatory systems. Our approaches extract useful information from those genome-wide measurements for effectively modeling the logic of gene expression regulation. We present a predictive model for the prediction of gene expression from ChIP-Seq signals, based on quantitative modeling of regulator-gene association strength, principal component analysis, and regression-based model selection. We demonstrate the combinatorial regulation of TFs, and their power for explaining genome-wide gene expression variation. We also illustrate the roles of covalent histone modification marks on predicting gene expression and their regulation by TFs. We present a dynamical model of gene expression profiling, and derive the perturbed behaviors of the ordinary differential equation (ODE) system. Based on that, we present a regularized multivariate regression method for inferring the gene regulatory network of a stable cell type. We model the sparsity and stability of the network by a regularization approach. We applied the approaches to both a simulation data set and the RNAi perturbation data in mouse embryonic stem cells.

The ability to engineer complex genetic programs could have a huge impact on many industries, yielding organisms that can respond to their environment and perform functions relevant to manufacturing, agriculture, and medicine. However, such engineering efforts have proven difficult, in part because these programs often require precise levels of gene expression for proper function. It is especially tough to build programs that have robust activity, as any changes to the host cells can perturb the context of the genetic system and disrupt carefully tuned expression levels. Additionally, genetic programs often place high demands on host resources, which can adversely affect cell growth and further upset the intended function. In this thesis, we describe two regulatory systems in Escherichia coli that could serve to separate synthetic genetic programs from their host context, potentially leading to more robust activity. First, we build a 'resource allocator' by fragmenting T7 RNA polymerase variants into a conserved fragment and a set of variable fragments. The resource allocator limits the total number of polymerases that can be active in a genetic program, with the aim of protecting the host from being overburdened. This transcriptional budget can be allocated to different elements of the genetic program as necessary and further regulated using additional protein fragments. Second, we demonstrate a set of stabilized promoters that can maintain a level of gene expression independent of their genetic context. These promoters utilize a noncooperative incoherent feedforward loop to buffer differences in gene expression caused by changes in copy number. We demonstrate that stabilized promoters can be moved between plasmids and different locations on the genome with little change in expression. Further, they minimize the effects of other perturbations that can affect copy number, such as genome mutations and media composition.
