Book Description
The neural crest is a remarkable embryonic population of cells found only in vertebrates and has the potential to give rise to many different cell types contributing throughout the body. These derivatives range from the mesenchymal bone and cartilage comprising the facial skeleton, to neuronal derivatives of the peripheral sensory and autonomic nervous systems, to melanocytes throughout the body, and to smooth muscle of the great arteries of the heart. For these cells to correctly progress from an unspecifi ed, nonmigratory population to a wide array of dynamic, differentiated cell types-some of which retain stem cell characteristics presumably to replenish these derivatives-requires a complex network of molecular switches to control the gene programs giving these cells their defi ning structural, enzymatic, migratory, and signaling capacities. This review will bring together current knowledge of neural crest-specifi c transcription factors governing these progressions throughout the course of development. A more thorough understanding of the mechanisms of transcriptional control in differentiation will aid in strategies designed to push undifferentiated cells toward a particular lineage, and unraveling these processes will help toward reprogramming cells from a differentiated to a more naive state.

Book Description
This SpringerBrief explores unconventional functions of eight different transcription factors and concludes with a discussion of their biological significance and impact, including effects on processes within the cell nucleaus during development and in adult organisms. Chapter One details unconventional functions of the transcription factors GAGA, HP1, Rb, STAT, ATF-2 and NF-kB. Surprisingly, all of these transcription factors can be found in association with heterochromatin as well as euchromatin, and in some cases unconventional functions have been demonstrated for these heterochromatin-associated factors. Chapter Two focuses on the unconventional functions of STAT and HP1 and discusses their roles in the promotion of longevity, and in protection from cancer and DNA damage. Chapter Three explores the biological significance of the findings presented in the first two chapters and considers how global changes in the epigenome brought about by factors such as STAT and HP1 might affect processes within the cell nucleus during development and in adult organisms. This succinct yet thorough SpringerBrief is essential for researchers studying epigenetics, and to instructors of the subject. It should also appeal to people interested in the control of gene transcription and other processes in the cell nucleus, and to those interested in development.

Book Description
Many inheritable changes in gene function are not explained by changes in the DNA sequence. Such epigenetic mechanisms are known to influence gene function in most complex organisms and include effects such as transposon function, chromosome imprinting, yeast mating type switching and telomeric silencing. In recent years, epigenetic effects have become a major focus of research activity. This monograph, edited by three well-known biologists from different specialties, is the first to review and synthesize what is known about these effects across all species, particularly from a molecular perspective, and will be of interest to everyone in the fields of molecular biology and genetics.

Book Description
Eggs of all animals contain mRNAs and proteins that are supplied to or deposited in the egg as it develops during oogenesis. These maternal gene products regulate all aspects of oocyte development, and an embryo fully relies on these maternal gene products for all aspects of its early development, including fertilization, transitions between meiotic and mitotic cell cycles, and activation of its own genome. Given the diverse processes required to produce a developmentally competent egg and embryo, it is not surprising that maternal gene products are not only essential for normal embryonic development but also for fertility. This review provides an overview of fundamental aspects of oocyte and early embryonic development and the interference and genetic approaches that have provided access to maternally regulated aspects of vertebrate development. Some of the pathways and molecules highlighted in this review, in particular, Bmps, Wnts, small GTPases, cytoskeletal components, and cell cycle regulators, are well known and are essential regulators of multiple aspects of animal development, including oogenesis, early embryogenesis, organogenesis, and reproductive fitness of the adult animal. Specific examples of developmental processes under maternal control and the essential proteins will be explored in each chapter, and where known conserved aspects or divergent roles for these maternal regulators of early vertebrate development will be discussed throughout this review.

Book Description
Abstract: Dissecting the complex circuitry of the cell is a principal challenge in the post-genomic era. Advances in the fields of molecular biology and bioinformatics have made this problem more amenable to an engineering approach, where components are characterized and assembled to elicit predefined behaviors. In this work we implement an approach which combines computational and experimental techniques to develop artificial gene networks that are used to explore the molecular and biochemical interactions which coordinate cell function. We present the design, construction, and analysis of robust genetic switches in the single-celled eukaryote Saccharomyces cerevisiae , including a bistable switch analogous to an electrical toggle switch. The S. cerevisiae genetic toggle switch allows reversible control of target gene expression in response to an externally applied chemical signal, with up to a 100-fold difference between stable ON and OFF target gene expression states. This functional bistable switch has potential biotechnological and biomedical applications. In addition, we present an experimental and theoretical investigation of the origins and consequences of stochasticity in gene expression in eukaryootc cells. By utilizing well-characterized artificial gene networks, we modulate the expression of a single gene in S. cerevisiae and combine our results with in silico stochastic models of specific eukaryotic transcription mechanisms. A key result of our combined approach addresses the sensitivity of noise in eukaryotic gene expression to the level of transcription and proposes a possible role for the transcription apparatus assembly in modulating such noise. Further, we demonstrate a plausible mechanism for heritable changes in target gene expression whereby increased levels of noise in the expression of a regulatory protein causes a population of isogenic cells to exhibit bistable expression states. Together, our findings address the origins, propagation, and consequences of noise in the expression of eukaryotic genes, and provide insight into the biological design principles involved in noise modulation.

Book Description
This book discusses the regulation of gene transcription by neuronal activity that is evident in a large number of neuronal processes ranging from neural development and refinement of neuronal connections to learning and response to injury. Transcriptional Regulation by Neuronal Activity: To the Nucleus and Back, 2nd edition illustrates how signals are transmitted to the nucleus in response to neuronal activity, which genes are regulated and how this is achieved, and how these changes in gene expression alter neuronal function. The aim of this second edition is to highlight key advances in the field since the first edition. The book is divided into four sections. The first highlights how signals get to the nucleus from the membrane in response to synaptic or neuronal activity. Included are chapters on the pathways that transmit signals from synapses to nuclei. The second section focuses on epigenetic regulatory processes of activity-induced gene transcription, an area that has exploded in the past few years. The third section navigates the role of activity-induced genes in physiological processes such as learning and memory, and human developmental disorders such as those associated with the autism spectrum. The fourth section highlights groundbreaking technological advances in the field, which have allowed activity-regulated transcription to be used as a tool to study learning and memory.
