Regulation Of Gene Expression In The Tumor Environment

It is now becoming very clear that the development and progression of tumor towards the malignant (metastatic) phenotype depends tightly on the interaction between the tumor cells and the tumor microenvironment. Tumor cells respond to stimuli generated within the tumor microenvironment for their growth advantage while the tumor cell themselves reshape and remodel the architecture and function of their extracellular matrices. The term tumor microenvironment is a wide umbrella consisting of stromal cells such as fibroblasts and endothelial cells and infiltration immune cells including T and B cells, macrophages, and other inflammatory cells (PMNs). These different components of the tumor microenvironment could have stimulatory and inhibitory effects on tumor progression by regulating the gene expression repertoire within the tumor cells on one hand and the stroma cells on the other. In this volume we have seven contributors who will discuss several different aspects on the cross talk within the tumor microenvironment components leading to the acquisition of the metastatic phenotype. It is our hope that these state-of-the-art studies will shed further light on our understanding of these complicated processes.

Differential gene regulation and targeted therapy are the critical aspects of several cancers. This book covers specific gene regulation and targeted therapies in different malignancies. It offers a comprehensive assessment of the transcriptional dysregulation in cancer, and considers some examples of transcriptional regulators as definitive oncogenic drivers in solid tumors, followed by a brief discussion of transcriptional effectors of the programs they drive, and discusses its specific targets. Most targeted therapeutics developed to date have been directed against a limited set of oncogenic drivers, exemplified by those encoding cell surface or cytoplasmic kinases that function in intracellular signaling cascades.

New Horizons in Health discusses how the National Institutes of Health (NIH) can integrate research in the social, behavioral, and biomedical sciences to better understand the causes of disease as well as interventions that promote health. It outlines a set of research priorities for consideration by the Office of Behavioral and Social Sciences Research (OBSSR), with particular attention to research that can support and complement the work of the National Institutes of Health. By addressing the range of interactions among social settings, behavioral patterns, and important health concerns, it highlights areas of scientific opportunity where significant investment is most likely to improve nationalâ€"and globalâ€"health outcomes. These opportunities will apply the knowledge and methods of the behavioral and social sciences to contemporary health needs, and give attention to the chief health concerns of the general public.

The cause of cancer and its many manifestations is at present unknown. Since many of its manifestations, including is control of cell division, appear to represent abnormal patterns of gene expression, studies of the regulation of gene expression nwill provide important insights in the understanding and treatment of cancer. This volume attempts to present some of the recent work on regulation of gene expression in eukaryotic cells.

Metabolic programs of individuals are key determinants for disease susceptibility and immune response. This book, edited by experts in the field, summarizes epigenetic signaling pathways that regulate metabolic programs associated with cancer and cancer-related secondary diseases. The first part of the book highlights key metabolic pathways that are implicated in cancer and provides a comprehensive overview on the carbohydrate, protein, lipid, amino- and nucleic acid metabolic pathways that are deregulated in cancer. Special attention is paid to the altered tumor micro-environment that is influenced by the metabolic milieu. Furthermore, the fundamental relationship between the cellular metabolic environment and cell death-mediated autophagy is discussed. The second part of the book covers our understanding of the fundamental epigenetic regulations that are implicated in controlling the metabolic programs in cancer cells. Many aspects of epigenetic regulation of non-coding RNAs as well as DNA/RNA methylation, which influencing metabolic homeostasis in cancer, are discussed in detail. Special emphasis is placed on the epigenetic regulation of the amino acid, glucose/carbohydrate metabolism and epigenetic regulation during hypoxia and its connection to cancer. Last but not least, the third part of the book covers small molecule modulators of histone modifying enzymes, which can be used as therapeutic tools. The readers learn about the cross-talk between epigenetics and immunometabolims, as well as the epigenetic regulation of oncometabolites to combat cancer. Given its scope, the book will appeal to a broad readership interested in epigenetic, cancer and metabolic research.

Overall, this book illustrates the complexities of the regulation and deregulation of genes mediated through epigenetics in the development and progression of human malignancies. All the articles have been carefully chosen to represent several cancer systems with state of our knowledge on the role of epigenetic deregulation of microRNAs (miRNAs) and their target mRNAs along with epigenetic deregulation of mRNAs. This book also illustrates the role of several dietary agents, collectively called nutraceuticals or natural agents in modulating the epigenetic reprogramming of miRNAs and mRNAs for the prevention and/or treatment of human malignancies. It is well known that genetic aberrations, especially inherited through parents (somatic genetic alterations) contribute to the development of less than 10% of all cancer yet epigenetic alterations in genes especially through selective methylation and acetylation appears to be responsible for the development and progression of the vast majority of all cancers. Therefore, understanding the role of epigenetics in the regulation of genes especially through deregulated expression of miRNAs as presented in this book will allow scientists to devise targeted therapeutic strategies for re-expression of the lost genes or down-regulate the genes that are over-expressed in order to eradicate cancer. It is hoped that targeting epigenetics will not only target cancer cells but it will also target the tumor microenvironment (more like the entire tumor environment such as the entire host) for achieving better treatment outcomes for patients diagnosed with cancer which will lead to achieve the long-term objective for complete eradication of cancer. This book contains fifteen chapters which begins with the concept of systems and network biology for investigating the epigenetics of cancer followed by a series of articles on the role of miRNAs and their target genes in the biology of pancreatic cancer and other cancers such as breast, kidney, prostate and and colon. Since it is becoming increasingly clear that cancer stem cells (CSCs) are important in the development and progression of cancer, and CSCs are important in therapeutic resistance, treatment failure and tumor recurrence, thus the importance of CSCs and epigenetics has been highlighted by a very timely article on epigenetic variations of stem cell markers in cancer including miRNAs. Moreover, just targeting heterogeneous cancer cell populations may not be optimal to eradicate tumors and for which one must take a holistic approach for developing drugs that could also target the tumor microenvironment and tumor dormancy that are regulated through epigenetics. Keeping abreast with this thought process the concluding chapter provides a concept towards curative cancer therapy with maspin, which could be a unique window of opportunity to target tumor dormancy. Therefore, it suggest that targeting the tumor dormancy and the tumor microenvironment using novel therapeutics specifically by targeting epigenetics would become the future of medicine.

Part A of the first volume in the series Current Perspectives on Molecular and Cellular Oncology. Topics covered include the molecular genetic approach towards senscence and immortalization and neoplastic transformation in human cell systems in culture.

In recent years, the field of epigenetics has grown significantly, driving new understanding of human developmental processes and disease expression, as well as advances in diagnostics and therapeutics. As the field of epigenetics continues to grow, methods and technologies have multiplied, resulting in a wide range of approaches and tools researchers might employ. Epigenetics Methods offers comprehensive instruction in methods, protocols, and experimental approaches applied in field of epigenetics. Here, across thirty-five chapters, specialists offer step-by-step overviews of methods used to study various epigenetic mechanisms, as employed in basic and translational research. Leading the reader from fundamental to more advanced methods, the book begins with thorough instruction in DNA methylation techniques and gene or locus-specific methylation analyses, followed by histone modification methods, chromatin evaluation, enzyme analyses of histone methylation, and studies of non-coding RNAs as epigenetic modulators. Recently developed techniques and technologies discussed include single-cell epigenomics, epigenetic editing, computational epigenetics, systems biology epigenetic methods, and forensic epigenetic approaches. Epigenetics methods currently in-development, and their implication for future research, are also considered in-depth.

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
