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.

An early view of eukaryotic chromosomes was that of static structures, which stored DNA not in use within a given cell type. It was thought that packaging of DNA into higher levels of chromatin structure would suffice to repress gene expression and that the challenge to the cell would be to rescue specific sequences from these structures. The exten sive packaging of inactive DNA was considered the primary difference between eukaryotic and prokaryotic genomes and except for that point both would be similarly regulated by cis-acting sequences and trans acting factors. Our view of eukaryotic chromosomes has evolved dra matically over the last decade. The picture of chromosomes that is emerging is that of dynamic breathing organelles actively regulating the flow of genetic information from the genome. Indeed chromatin is so fluid that even maintaining gene quiescence is an active process and is tightly regulated. Chromatin dynamics is a consequence of protein complexes that modify histones, remove histone modifications, mobi lize nucleosomes or stabilize nucleosomes. Awide variety of such com plexes have now been described. Some are abundant and may play glo bal roles in chromosome fluidity and function. Others are more rare and specialized for specific functions at discreet loci. Moreover, several complexes share biochemical activities and genetic studies suggest overlapping functions in vivo. Many components of these complexes were first revealed in genetic screens, while others were discovered by novel cell biological or biochemical approaches.

Sex Differences in the Central Nervous System offers a comprehensive examination of the current state of sex differences research, from both the basic science and clinical research perspectives. Given the current NIH directive that funded preclinical research must consider both females and males, this topic is of interest to an increasing percentage of the neuroscience research population. The volume serves as an invaluable resource, offering coverage of a wide range of topics: sex differences in cognition, learning, and memory, sex hormone signaling mechanisms, neuroimmune interactions, epigenetics, social behavior, neurologic disease, psychological disorders, and stress. Discussions of research in both animal models and human patient populations are included. Details how sex hormones have widespread effects on the nervous system and influence the way males and females function Assists readers in determining how sex impacts their research and practice, and assists in determining how to adjust research programs to incorporate sex influences Includes discussions of research in both animal models and human patient populations, and at various developmental stages Features revised and updated chapters by leaders in the field around the globe—the broadest, most expert coverage available

Dental defects may be the physical expression of genetic defects, and so they can often be seen in a variety of syndromes associated with malformations of organs. However, dental defects are often not recognized, identified, nor characterised despite representing a possible diagnostic sign for an undiagnosed condition. This book addresses this gap by providing an understanding of dental genetics and its developmental biology counterpart. With approximately seventy well-illustrated examples, the authors present the clinical oro-facial manifestations accompanying various syndromes, providing the necessary knowledge for diagnostic purposes, as well as giving insight into recent development for each specific condition. The clarity and format of this book make it an ideal support guide both in the clinic and while conducting research. Comprehensive examination of dento/oro/craniofacial anomalies Well-illustrated examples Presented in a compact, easy to use format

This textbook aims to describe the fascinating area of eukaryotic gene regulation for graduate students in all areas of the biomedical sciences. Gene expression is essential in shaping the various phenotypes of cells and tissues and as such, regulation of gene expression is a fundamental aspect of nearly all processes in physiology, both in healthy and in diseased states. This pivotal role for the regulation of gene expression makes this textbook essential reading for students of all the biomedical sciences, in order to be better prepared for their specialized disciplines. A complete understanding of transcription factors and the processes that alter their activity is a major goal of modern life science research. The availability of the whole human genome sequence (and that of other eukaryotic genomes) and the consequent development of next-generation sequencing technologies have significantly changed nearly all areas of the biological sciences. For example, the genome-wide location of histone modifications and transcription factor binding sites, such as provided by the ENCODE consortium, has greatly improved our understanding of gene regulation. Therefore, the focus of this book is the description of the post-genome understanding of gene regulation. The purpose of this book is to provide, in a condensed form, an overview on the present understanding of the mechanisms of gene regulation. The authors are not aiming to compete with comprehensive treatises, but rather focus on the essentials. Therefore, the authors have favored a high figure-to-text ratio following the rule stating that “a picture tells more than thousand words”. The content of the book is based on the lecture course, which is given by Prof. Carlberg since 2001 at the University of Eastern Finland in Kuopio. The book is subdivided into 4 sections and 13 chapters. Following the Introduction there are three sections, which take a view on gene regulation from the perspective of transcription factors, chromatin and non-coding RNA, respectively. Besides its value as a textbook, Mechanisms of Gene Regulation will be a useful reference for individuals working in biomedical laboratories.
