Book Description :

Polycomb Group Proteins is a comprehensive volume detailing the mechanisms that are key to the management of genome function in many different contexts, from embryonic stem cells to terminal differentiation. The book discusses the regulation of cell lineages, cell proliferation, apoptosis, X chromosome inactivation, and most major genome programming choices. In the last few years, the biochemical understanding of PRC1-type complexes has greatly expanded in terms of the number of components involved and the intricacies of their interactions. The functionalities of these various complexes and their components are not all well understood, but recent work has shown an important division of labor and roles in the recruitment of stable binding in the ability to lay the groundwork of histone modifications and in the epigenetic maintenance of repressed states. In an effort to provide clarity in this topical research area, the book provides a cluster of chapters that deal with variant PRC1 complexes, their taxonomy, their components, their interactions, and what is known of their functions. Provides topical coverage on accessory components that are known to be involved in PcG recruitment in Drosophila and their less understood role in mammals Includes dedicated sections on PRC1 complexes and PRC2 complexes for quick reference Features the role of RNA molecules in different aspects of Polycomb proteins involvement in epigenetic regulation, beginning with the key role of the Xist RNA in recruiting and spreading PcG complexes on the inactive X chromosome

Book Description :

Epigenetic Gene Expression and Regulation reviews current knowledge on the heritable molecular mechanisms that regulate gene expression, contribute to disease susceptibility, and point to potential treatment in future therapies. The book shows how these heritable mechanisms allow individual cells to establish stable and unique patterns of gene expression that can be passed through cell divisions without DNA mutations, thereby establishing how different heritable patterns of gene regulation control cell differentiation and organogenesis, resulting in a distinct human organism with a variety of differing cellular functions and tissues. The work begins with basic biology, encompasses methods, cellular and tissue organization, topical issues in epigenetic evolution and environmental epigenesis, and lastly clinical disease discovery and treatment. Each highly illustrated chapter is organized to briefly summarize current research, provide appropriate pedagogical guidance, pertinent methods, relevant model organisms, and clinical examples. Reviews current knowledge on the heritable molecular mechanisms that regulate gene expression, contribute to disease susceptibility, and point to potential treatment in future therapies Helps readers understand how epigenetic marks are targeted, and to what extent transgenerational epigenetic changes are instilled and possibly passed onto offspring Chapters are replete with clinical examples to empower the basic biology with translational significance Offers more than 100 illustrations to distill key concepts and decipher complex science

Book Description :

Myelodysplastic syndromes (MDS) are the most common hematological malignancies involving mostly the elderly population. The major morbidity relates to patients’ symptomatic cytopenias.MDS was previously named as “preleukemia “ or “ smoldering leukemia” as the lack of terminal cells in MDS and because about 25% of all cases progresses into acute myeloid leukemia. According to various reports the annual incidence of MDS ranges widely from 2-12 per 100.000, increasing to 30-50 cases per 100.000 among persons aged 70 or older. It is believed that the true incidence of MDS have been underestimated however it seems to be comparable to that for multiple myeloma and chronic lymphocytic leukemia. In the past decade much progress had been made; we know more on the disease pathology, there is more emphasis on the care and more targeted therapy had been invested. Athors provide updated knowledge in this book on all clinically important aspects of the disease. Hot topics of our days are discussed in chapters by outstanding and well known scientists from all over the world. We would offer this product both for medical students and postgraduates as well as for all who are interested in this very exciting and fast progressing field of hematology. With this work authors should call attention on the disease for decision makers in healt care systems as well.

Book Description :

With the appearance of methods for the sequencing of genomes and less expensive next generation sequencing methods, we face rapid advancements of the -omics technologies and plant biology studies: reverse and forward genetics, functional genomics, transcriptomics, proteomics, metabolomics, the movement at distance of effectors and structural biology. From plant genomics to plant biotechnology reviews the recent advancements in the post-genomic era, discussing how different varieties respond to abiotic and biotic stresses, understanding the epigenetic control and epigenetic memory, the roles of non-coding RNAs, applicative uses of RNA silencing and RNA interference in plant physiology and in experimental transgenics and plants modified to specific aims. In the forthcoming years these advancements will support the production of plant varieties better suited to resist biotic and abiotic stresses, for food and non-food applications. This book covers these issues, showing how such technologies are influencing the plant field in sectors such as the selection of plant varieties and plant breeding, selection of optimum agronomic traits, stress-resistant varieties, improvement of plant fitness, improving crop yield, and non-food applications in the knowledge based bio-economy. Discusses a broad range of applications: the examples originate from a variety of sectors (including in field studies, breeding, RNA regulation, pharmaceuticals and biotech) and a variety of scientific areas (such as bioinformatics, -omics sciences, epigenetics, and the agro-industry) Provides a unique perspective on work normally performed 'behind closed doors'. As such, it presents an opportunity for those within the field to learn from each other, and for those on the 'outside' to see how different groups have approached key problems Highlights the criteria used to compare and assess different approaches to solving problems. Shows the thinking process, practical limitations and any other considerations, aiding in the understanding of a deeper approach

Book Description :

Polycomb group (PcG) proteins are well-conserved chromatin factors that repress the transcription of their target genes. They bind to the genome at specific sites and act on chromatin through the regulation of both post-translational histone modifications and higher-order chromatin structure. Aberrant expression of multiple PcG genes are implicated in different types of human cancers. PcGs are considered as novel prognostic markers both in terms of improving diagnosis as well as predicting patient response to treatment. Pharmacological targeting of PcG proteins is emerging as an attractive strategy. In addition, some nutrients can modify the expression of PcG proteins in physiologic and pathologic processes.

Book Description :

Chromatin Signaling and Diseases covers the molecular mechanisms that regulate gene expression, which govern everything from embryonic development, growth, and human pathologies associated with aging, such as cancer. This book helps researchers learn about or keep up with the quickly expanding field of chromatin signaling. After reading this book, clinicians will be more capable of explaining the mechanisms of gene expression regulation to their patients to reassure them about new drug developments that target chromatin signaling mechanisms. For example, several epigenetic drugs that act on chromatin signaling factors are in clinical trials or even approved for usage in cancer treatments, Alzheimer's, and Huntington's diseases. Other epigenetic drugs are in development to regulate various class of chromatin signaling factors. To keep up with this changing landscape, clinicians and doctors will need to stay familiar with genetic advances that translate to clinical practice, such as chromatin signaling. Although sequencing of the human genome was completed over a decade ago and its structure investigated for nearly half a century, molecular mechanisms that regulate gene expression remain largely misunderstood. An emerging concept called chromatin signaling proposes that small protein domains recognize chemical modifications on the genome scaffolding histone proteins, facilitating the nucleation of enzymatic complexes at specific loci that then open up or shut down the access to genetic information, thereby regulating gene expression. The addition and removal of chemical modifications on histones, as well as the proteins that specifically recognize these, is reviewed in Chromatin Signaling and Diseases. Finally, the impact of gene expression defects associated with malfunctioning chromatin signaling is also explored. Explains molecular mechanisms that regulate gene expression, which governs everything from embryonic development, growth, and human pathologies associated with aging Educates clinicians and researchers about chromatin signaling, a molecular mechanism that is changing our understanding of human pathology Explores the addition and removal of chemical modifications on histones, the proteins that specifically recognize these, and the impact of gene expression defects associated with malfunctioning chromatin signaling Helps researchers learn about the quickly expanding field of chromatin signaling
