This book was released on 2013-05-22 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume describes the latest findings on transcriptional and translational regulation of stem cells. Both transcriptional activators and repressors have been shown to be crucial for the maintenance of the stem cell state. A key element of stem cell maintenance is repression of differentiation factors or developmental genes – achieved transcriptionally, epigenetically by the Polycomb complex, and post-transcriptionally by RNA-binding proteins and microRNAs. This volume takes two approaches to this topic – (1) illustrating the general principles outlined above through a series of different stem cell examples – embryonic, iPS and adult stem cells, and (2) describing several molecular families that have been shown to have roles in regulation of multiple stem cell populations.

This book was released on 2009-03-04 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stem cells appear to be fundamental cellular units associated with the origin of multicellular organisms and have evolved to function in safeguarding the cellular homeostasis in organ t- sues. The characteristics of stem cells that distinguish them from other cells have been the fascinating subjects of stem cell research. The important properties of stem cells, such as ma- tenance of quiescence, self-renewal capacity, and differentiation potential, have propelled this exciting ?eld and presently form a common theme of research in developmental biology and medicine. The derivation of pluripotent embryonic stem cells, the prospective identi?cation of multipotent adult stem cells, and, more recently, the induced pluripotent stem cells (popularly called iPS) are important milestones in the arena of stem cell biology. Complex networks of transcription factors, different signaling molecules, and the interaction of genetic and epi- netic events constantly modulate stem cell behavior to evoke programming and reprogramming processes in normal tissue homeostasis during development. In any given cellular scenario, the regulatory networks can pose considerable complexity and yet exert an orderly control of stem cell differentiation during normal development. An aberration in these ?nely tuned processes during development usually results in a spectrum of diseases such as cancers and neurological disorders.

Download or read book Transcriptional and Translational Control in Cell Fate Determination written by Soroush Tahmasebi and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-cellular organisms generate functional and morphological diversity in their cells through spatiotemporal regulation of gene expression. Gene expression is regulated through multiple mechanisms at the levels of transcription, translation, and degradation. During my PhD studies, I examined transcription factor-induced somatic-to-induced pluripotent stem cell reprogramming. For this, I adopted two different strategies that are based on transcriptional regulation by post-translational modification and translational control by the translational repressor 4E-BP. Specifically, in the project described in Chapter III, I studied the role of sumoylation in controlling the transcriptional activity of KLF4, KLF2, and KLF5 during reprogramming and adipocyte differentiation. I also explored the role of Ubc9, the sole SUMO-conjugating enzyme, in reprogramming and adipogenesis. These results and a comprehensive review of related studies, presented in Chapter I, have ...

Download or read book Genome Binding and Gene Regulation by Stem Cell Transcription Factors written by and published by . This book was released on 2016 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly all cells of an individual organism contain the same genome. However, each cell type transcribes a different set of genes due to the presence of different sets of cell type-specific transcription factors. Such transcription factors bind to regulatory regions such as promoters and enhancers and regulate their activity in gene transcription. Transcription factors interact with each other and form tissue-specific transcription factor networks. Identification of genome binding and gene regulation by transcription factors will enhance our understanding of how transcription factors specify cell types. Chapter 1 serves as a general introduction into eukaryotic transcription regulation and describes the role of enhancers and transcription factors. Chapters 2 - 4 describe the experimental work of this thesis. Chapter 2 describes Chromatin Immunoprecipitation followed by Mass Spectrometry (ChIP-MS), a technique used to identify transcription factors and other genome binding proteins that bind to promoters, enhancers or heterochromatin. Chapter 2 specifically describes the genome-binding pattern of transcription- and pluripotency factor Dppa2, which we identify by ChIP-MS and ChIP-seq to bind to promoters outside the classical pluripotency network. Chapter 3 describes a transcription factor interaction network of over 200 proteins in neural stem cells, which was assembled by the identification of interaction partners of four mental disorder-associated transcription factors. Chapter 4 describes work on the genome-wide localization of Oct4, Sox2 and Nanog in embryonic stem cells and investigates the genome localization of these transcription factors upon depletion of Oct4 or Sox2 from embryonic stem cells. The last chapter, Chapter 5, summarizes the results from Chapter 2-4 and provides additional discussion to these chapters, concerning its implications and future directions.

Download or read book Translational Regulation of Gene Expression 2 written by J. Ilan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, which results from the dramatic increase in interest in the control mechanism employed in gene expression and the importance of the regulated proteins, presents new information not covered in Translational Regulation of Gene Expression, which was published in 1987. It is not a revision of the earlier book but, rather, an extension of that volume witl, special emphasis on mecha nIsm. As the reader will discover, there is enormous diversity in the systems employing genes for translational regulation in order to regulate the appearance of the final product-the protein. Thus, we find that important proteins such as protooncogenes, growth factors, stress proteins, cytokines, lymphokines, iron storage and iron-uptake proteins, and a panorama of prokaryotic proteins, as well as eukaryotic viral proteins, are translationally regulated. Since for some gene products the degree of control is greater by a few orders of magnitude than their transcription, we can state that for these genes, at least, the expression is translationall y controlled. Translational regulation of gene expression in eukaryotes has emerged in the last few years as a major research field. The present book describes mechanisms of translational regulation in bacteria, yeast, and eukaryotic viruses, as well as in eukaryotic genes. In this book we try to provide in-depth coverage by including important examples from each group rather than systematically including all additional systems not described in the previous volume.

Download or read book Patterning and Cell Type Specification in the Developing CNS and PNS written by and published by Academic Press. This book was released on 2013-05-06 with total page 993 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genetic, molecular, and cellular mechanisms of neural development are essential for understanding evolution and disorders of neural systems. Recent advances in genetic, molecular, and cell biological methods have generated a massive increase in new information, but there is a paucity of comprehensive and up-to-date syntheses, references, and historical perspectives on this important subject. The Comprehensive Developmental Neuroscience series is designed to fill this gap, offering the most thorough coverage of this field on the market today and addressing all aspects of how the nervous system and its components develop. Particular attention is paid to the effects of abnormal development and on new psychiatric/neurological treatments being developed based on our increased understanding of developmental mechanisms. Each volume in the series consists of review style articles that average 15-20pp and feature numerous illustrations and full references. 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

Download or read book The Transcriptional Regulation of Stem Cell Differentiation Programs by Hedgehog Signalling written by Anastassia Voronova and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hedgehog (Hh) signalling pathway is one of the key signalling pathways orchestrating intricate organogenesis, including the development of neural tube, heart and skeletal muscle. Yet, insufficient mechanistic understanding of its diverse roles is available. Here, we show the molecular mechanisms regulating the neurogenic, cardiogenic and myogenic properties of Hh signalling, via effector protein Gli2, in embryonic and adult stem cells. In Chapter 2, we show that Gli2 induces neurogenesis, whereas a dominant-negative form of Gli2 delays neurogenesis in P19 embryonal carcinoma (EC) cells, a mouse embryonic stem (ES) cell model. Furthermore, we demonstrate that Gli2 associates with Ascl1/Mash1 gene elements in differentiating P19 cells and activates the Ascl1/Mash1 promoter in vitro. Thus, Gli2 mediates neurogenesis in P19 cells at least in part by directly regulating Ascl1/Mash1 expression. In Chapter 3, we demonstrate that Gli2 and MEF2C bind each other's regulatory elements and regulate each other's expression while enhancing cardiomyogenesis in P19 cells. Furthermore, dominant-negative Gli2 and MEF2C proteins downregulate each other's expression while imparing cardiomyogenesis. Lastly, we show that Gli2 and MEF2C form a protein complex, which synergistically activates cardiac muscle related promoters. In Chapter 4, we illustrate that Gli2 associates with MyoD gene elements while enhancing skeletal myogenesis in P19 cells and activates the MyoD promoter in vitro. Furthermore, inhibition of Hh signalling in muscle satellite cells and in proliferating myoblasts leads to reduction in MyoD and MEF2C expression. Finally, we demonstrate that endogenous Hh signalling is important for MyoD transcriptional activity and that Gli2, MEF2C and MyoD form a protein complex capable of inducing skeletal muscle-specific gene expression. Thus, Gli2, MEF2C and MyoD participate in a regulatory loop and form a protein complex capable of inducing skeletal muscle-specific gene expression. Our results provide a link between the regulation of tissue-restricted factors like Mash1, MEF2C and MyoD, and a general signal-regulated Gli2 transcription factor. We therefore provide novel mechanistic insights into the neurogenic, cardiogenic and myogenic properties of Gli2 in vitro, and offer novel plausible explanations for its in vivo functions. These results may also be important for the development of stem cell therapy strategies.
