Book Synopsis Transcriptional Control of Neural Crest Development by : Brian L. Nelms
Download or read book Transcriptional Control of Neural Crest Development written by Brian L. Nelms and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: In his 1894 book, Materials for the Study of Variation, William Bateson coined the term Homoeosis with the following prose: The case of the modification of the antenna of an insect into a foot, of the eye of a Crustacean into an antenna, of a petal into a stamen, and the like, are examples of the same kind. It is desirable and indeed necessary that such Variations, which consist in the assumption by one member of a Meristic series, of the form or characters proper to other members of the series, should be recognized as constituting a distinct group of phenomena. ...I therefore propose...the term HOMOEOSIS...; for the essential phenomenon is not that there has merely been a change, but that something has been changed into the likeness of something else. The book was intended as a listing of the kinds of naturally occurring variation that could act as a substrate for the evolutionary process and Bateson took his examples from collections, both private and in museums, of materials displaying morphological oddities. Interestingly the person who also coined the term “Genetics” proffered little in the way of speculation on the possible genetic underpinnings of these oddities. It wasn’t until the early part of the next century that these changes in meristic series were shown to be heritable.

Book Synopsis Guidebook to the Homeobox Genes by : Denis Duboule
Download or read book Guidebook to the Homeobox Genes written by Denis Duboule and published by . This book was released on 1994 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This much-needed guidebook provides research workers with the most up-to-date reference available on homeobox genes. As the tenth anniversary of the discovery of the homeobox fast approaches, these genes are being isolated from an ever-widening group of organisms and are now understood as critical to numerous developmental processes. But the rapidly increasing pool of information on homeobox genes has often resulted in a lack of coordination in the use of nomenclature and classification systems. As a result, the field has been sometimes characterized by its confusing and scattered literature. This book provides an overview of the subject by summarizing the dispersed findings and by listing key references. The first two chapters give a brief historical account of the discovery of the homeobox and introduce the reader to its role in development. The third chapter provides comprehensive coverage to the classification and structural organization of the homeobox genes. Finally, short descriptions of individual homeobox genes are provided in alphabetical order at the end of the book. Guidebook to the Homeobox Genes, with its easy-to-use format, offers a quick and simple way to learn about the essentials of each gene with cogent descriptions and helpful references . It will be welcomed by students and professionals in developmental biology, molecular genetics, and molecular biology.
Book Synopsis Hox Modules in Evolution and Development by : David E. K. Ferrier
Download or read book Hox Modules in Evolution and Development written by David E. K. Ferrier and published by CRC Press. This book was released on 2023-04-14 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few, if any, genes have had the same level of impact on the field of evolutionary-developmental biology (evo-devo) as the Hox genes. These genes are renowned for their roles in patterning the body plans and development of the animal kingdom. This is complemented by the distinctive organisation of these genes in the genome, with them frequently being found as clusters in which gene position is linked to when and where the individual genes are expressed, particularly during embryogenesis. This book provides the latest overviews of Hox gene organisation and function for major clades of animals from across the animal kingdom. With the rapidly increasing availability of high-quality whole genome sequences from an ever-expanding range of species, it is becoming increasingly evident that there is great diversity in the organisation of Hox genes. These great strides in genome sequencing are wedded to important developments in our ability to detect expression and disrupt gene function in species that are not traditionally genetically-amenable animals. These technical developments are integrated with wide taxon-sampling in this volume to provide new perspectives on the roles of Hox genes in understanding fundamental issues such as embryo patterning, mechanisms of gene regulation, homology, evolvability, evolutionary novelties, phylogeny, the role of gene and genome duplications in evolution, and ancestral states for major clades of animals. Key features Integrative overviews from major animal groups including, arthropods, vertebrates, echinoderms, mollusks and other spiralians. Perspectives gleaned from the latest genome sequence and gene expression data. Individual chapters written by world-leading experts in Hox genes and evo-devo in each animal group.

Book Synopsis Organ- and Site-Specific HOX Gene Expression in Stromal Cells by : Caroline Ospelt
Download or read book Organ- and Site-Specific HOX Gene Expression in Stromal Cells written by Caroline Ospelt and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: HOX genes are a group of evolutionarily conserved genes that encode a family of transcription factors that regulate early developmental morphogenetic processes and continue to be expressed into adulthood. These highly conserved HOX factors play an unquestioned crucial role as master regulators during embryonic vertebrate development and morphogenesis by controlling the three dimensional body plan organization. HOX genes specify regions of the body plan of an embryo along the head-tail axis. They encode proteins that specify the characteristics of ,Äòposition,Äô, ensuring that the correct structures form in the correct places of the body. Expression of HOX is known to persist in many tissues in the postnatal period suggesting the role of these genes not only during development but also for the functioning of tissues throughout life. The tissue-specific pattern of HOX gene expression is inherent in stromal/stem cells of mesenchymal origin, such as mesenchymal stromal cells, fibroblasts, smooth muscle cells, and preadipocytes, enabling them to memorize their topographic location in the form of their HOX code and to fulfill their location-specific functions. In this chapter, we focus on the expression and potential role of HOX genes in adult tissues. We review evidence that site-specific expression of HOX genes is connected to location-specific disease susceptibility and review studies showing that dysregulated expression of HOX genes can be associated with various diseases. By recognizing the importance of site-specific molecular mechanisms in the organ stroma, we gain new insights into the processes underlying the site-specific manifestation of disease.
Book Synopsis The Neural Crest by : Nicole Le Douarin
Download or read book The Neural Crest written by Nicole Le Douarin and published by Cambridge University Press. This book was released on 1999-11-28 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 1999 edition of The Neural Crest contains comprehensive information about the neural crest, a structure unique to the vertebrate embryo, which has only a transient existence in early embryonic life. The ontogeny of the neural crest embodies the most important issues in developmental biology, as the neural crest is considered to have played a crucial role in evolution of the vertebrate phylum. Data that analyse neural crest ontogeny in murine and zebrafish embryos have been included in this revision. This revised edition also takes advantage of recent advances in our understanding of markers of neural crest cell subpopulations, and a full chapter is now devoted to cell lineage analysis. The major research breakthrough since the first edition has been the introduction of molecular biology to neural crest research, enabling an elucidation of many molecular mechanisms of neural crest development. This book is essential reading for students and researchers in developmental biology, cell biology, and neuroscience.

Volume 1 offers 48 high level articles devoted mainly to patterning and cell type specification in the developing central and peripheral nervous systems. Series offers 144 articles for 2904 full color pages addressing ways in which the nervous system and its components develop Features leading experts in various subfields as Section Editors and article Authors All articles peer reviewed by Section Editors to ensure accuracy, thoroughness, and scholarship Volume 1 sections include coverage of mechanisms which: control regional specification, regulate proliferation of neuronal progenitors and control differentiation and survival of specific neuronal subtypes, and controlling development of non-neural cells
Book Synopsis Evolution of Hox Gene Expression and Function and the Effect on Limb Specification in Arthropods by : Cheryl Chih-Jui Hsia
Download or read book Evolution of Hox Gene Expression and Function and the Effect on Limb Specification in Arthropods written by Cheryl Chih-Jui Hsia and published by . This book was released on 2007 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many common sets of genes are used to generate diverse animal body plans. One set of these genes are the Hox genes, transcription factors that specify segmental identity along the anterior-posterior axis of animals in early development. Many studies have been carried out to uncover how the evolution of Hox genes and Hox gene function may have precipitated the evolution of diverse body plans. I carried out functional assays in Drosophila melanogaster embryos to explore whether changes in protein sequence may have facilitated the divergence of six-legged insects from multi-legged crustaceans. I developed fluorescent immunohistochemistry and double in situ hybridization methods in the crustacean, Artemia franciscana, to further clarify the HOX expression patterns in the trunk. From these studies, I found an example of a Hox gene capable of homeotic function, but inhibited from expression and presumably, inhibited from conferring segmental identity. This loss of segment identity function may contribute to the overall morphological body plan of Artemia to ensure the development of limbs throughout the trunk.

Book Synopsis The Regulatory Genome by : Eric H. Davidson
Download or read book The Regulatory Genome written by Eric H. Davidson and published by Elsevier. This book was released on 2010-07-19 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
