Book excerpt: Decades of research on the tumor suppressor p53 have revealed that it plays a significant role as a "guardian of the genome," protecting cells against genotoxic stress. In recent years, p53 research has begun to move into the clinic in attempts to understand how p53 is frequently inactivated in-and sometimes even promotes-human cancer. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine covers the rapid progress that has recently been made in basic and clinical research on p53. The contributors review new observations about its basic biology, providing updates on the functions of its isoforms and domains, the myriad stresses and signals that trigger its activation or repression, and its downstream effects on genome stability and the cell cycle that enforce tumor suppression in different cell and tissue types. They also discuss how p53 dysfunction contributes to cancer, exploring the various inherited and somatic mutations in the human TP53 gene, the impact of mutant p53 proteins on tumorigenesis, and the prognostic value and clinical outcomes of these mutations. Drugs that are being developed to respond to tumors harboring aberrant p53 are also described. This book is therefore essential reading for all cancer biologists, cell and molecular biologists, and pharmacologists concerned with the treatment of this disease.

Book excerpt: All of us have lurking in our DNA a most remarkable gene, which has a crucial job - it protects us from cancer. Known simply as p53, this gene constantly scans our cells to ensure that they grow and divide without mishap, as part of the routine maintenance of our bodies. If a cell makes a mistake in copying its DNA during the process of division, p53 stops it in its tracks, summoning a repair team before allowing the cell to carry on dividing. If the mistake is irreparable and the rogue cell threatens to grow out of control, p53 commands the cell to commit suicide. Cancer cannot develop unless p53 itself is damaged or prevented from functioning normally. Perhaps unsurprisingly, p53 is the most studied single gene in history. This book tells the story of medical science's mission to unravel the mysteries of this crucial gene, and to get to the heart of what happens in our cells when they turn cancerous. Through the personal accounts of key researchers, p53: The Gene that Cracked the Cancer Code reveals the fascination of the quest for scientific understanding, as well as the huge excitement of the chase for new cures - the hype, the enthusiasm, the lost opportunities, the blind alleys, and the thrilling breakthroughs. And as the long-anticipated revolution in cancer treatment tailored to each individual patient's symptoms begins to take off at last, p53 remains at the cutting edge. This timely tale of scientific discovery highlights the tremendous recent advances made in our understanding of cancer, a disease that affects more than one in three of us at some point in our lives.

This book was released on 2007-07-03 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current year (2004) marks the Silver Anniversary of the discovery of the p53 tumor suppressor. The emerging ?eld ?rst considered p53 as a viral antigen and then as an oncogene that cooperates with activated ras in transforming primary cells in culture. Fueling the concept of p53 acting as a transforming factor, p53 expression was markedly elevated in various transformed and tumorigenic cell lines when compared to normal cells. In a simple twist of fate, most of the studies conducted in those early years inadvertently relied on a point mutant of p53 that had been cloned from a normal mouse genomic library. A bona ?de wild-type p53 cDNA was subsequently isolated, ironically, from a mouse teratocarcinoma cell line. A decade after its discovery, p53 was shown to be a tumor suppressor that protects against cancer. It is now recognized that approximately half of all human tumors arise due to mutations within the p53 gene. As remarkable as this number may seem, it signi?cantly underrepresents how often the p53 pathway is targeted during tumorigenesis. It is my personal view, as well as many in the p53 ?eld, that the p53-signaling pathway is corrupted in nearly 100% of tumors. If you are interested in understanding cancer and how it develops, you must begin by studying p53 and its pathway. After demonstrating that p53 functions as a tumor suppressor the ?eld exploded and p53 became a major focus of scientists around the world.
Download or read book p53 Suppressor Gene written by Tapas Mukhopadhyay and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the p53 gene, one of the most frequently mutated or deleted genes in human cancers. The frequent occurrence of inactivated p53 implicates this gene product in the genesis of many human cancers. The p53 gene can suppress the growth of cancer cells and the transformation process by oncogenes. The p53 protein is a transcription factor that can repress or activate promoters containing one of three p53 DNA-binding motifs. The activity of p53 is regulated by phosphorylation and other transcription factors. Replacement of the p53 function or restoration of the p53 biochemical pathway is a focus of gene therapy.

Download or read book p53 Protocols written by Sumitra Deb and published by Springer Science & Business Media. This book was released on 2008-02-02 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of p53 as a tumor suppressor, numerous methods have evolved to reveal the unique structural features and biochemical functions of this protein. Several unique properties of p53 posed a challenge to understa- ing its normal function in the initial phase of its research. The low levels of p53 in normal cells, its stabilization under situations of genotoxic stress, induction of growth arrest, and apoptosis with stabilization of the protein, obstructed the visibility of its normal, unmutated function. The property of p53 that can sense a promoter and transactivate or inhibit is still not well understood. It is still not known whether it is the absence of the protein that causes tumorigenesis, or if its mutants have a dominant role in inducing cancer. p53 Protocols comprises eighteen chapters for the study of the diverse properties of p53 and related proteins. The methods included are invaluable for delineating the function of other proteins that may function as tumor suppr- sors or growth suppressors. The chapters are not presented in any schematic order, for the importance and diversity of the functions of p53 make it imp- sible to organize them suitably. We have made a sincere effort to collect the methods most useful to those investigators working on tumor suppressors or growth suppressors. The purpose of p53 Protocols is not only to provide investigators with methods to analyze similar biochemical functions, but also to familiarize them with the associated problems that arose during the course of investigations.

This book was released on 2012-12-06 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past five years have witnessed a remarkable development of interest in cell death 'from inside out'. After 30 years of relative obscurity, its quantitative importance in the building and maintenance of normal tissues, the subtle strategies involved in its regulation, and its significance in the pathogenesis of diseases of major social importance are becoming clear. Moreover, because a distinct set of biological events is involved in this death, these events themselves become reason able targets for new pharmacological agents in the treatment of cancer. The articles in this volume summarize the contents of a discussion meeting held at the Royal Society on 23 and 24 February 1994. The authors are a distinguished international group from a variety of disciplines in biology and medicine and hopefully their articles will convey something of the excitement of this fast-moving field. The three organizers are enormously indebted to all the contributors for the enthusiasm with which they delivered their talks, shared in discussion, and finally committed their contributions to these printed pages. We would also like to acknowledge the gracious way in which the Royal Society hosted the meeting, and in particular Mary Manning for making it the trouble-free and enjoyable experience that it was, and Janet Clifford and Simon Gribbin for skillfully managing the editorial processing of this volume.

Download or read book p53 written by Mumtaz Anwar and published by BoD – Books on Demand. This book was released on 2022-09-28 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: p53 is a protein that plays an important role in the regulation of cell division and thereby offers protection to the cell against malignant transformation. This is the most well-studied and most appreciated role of p53, due to which the protein is famously known as the “guardian of the genome.” It is the most studied protein in all forms of cancer research, with much of this research investigating p53’s role in tumor suppression. However, research has also shown that p53 plays a role in a wide range of other cellular functions, like serving as a biomarker for environmental pollution. Even as a tumor suppressor and transcription factor, many aspects of p53 function are still obscure, and research in the field is continually attempting to shed light on these functions. This book examines and discusses the myriad roles of p53 and different aspects of its functions. Chapters examine p53 in cancer prevention, DNA repair, gene regulation, and more.

Download or read book p53 written by Ayeda Ayed and published by Springer Science & Business Media. This book was released on 2010-12-16 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of human cancer in the past 40 years has been driven by linking innovative concepts and cutting edge technologies to key problems identified by clinical research. Some of the successes in cancer genetics identified from clinical work have been the identification of specific gene deletions in human chromosomes, the use of PCR-based cloning methodologies to identify and clone human cancer genes, the validation of the human cancer genes using transgenetic technologies in the mouse, and the ability to sequence whole genomes that has recently allowed a collation of all somatic and germline mutations in a human genome. In the same generation, entirely different disciplines involved in basic life science research have used model organisms like yeast, flies, worms, and cancer causing animal viruses as tools to develop windows to see into the machinery of the cell life cycle. The discoveries of pro-apoptotic genes, oncogenes, and covalent control mechanisms like phosphorylation and ubiquitination using the tools of science and technology have all been awarded Nobel prizes for their contribution to our understanding of how cells work. The discovery of p53 using the tumor causing animal virus SV40 falls into this pioneering period of biological and medical research.

Download or read book Ubiquitin and the Biology of the Cell written by Jan-Michael Peters and published by Springer Science & Business Media. This book was released on 1998-05-31 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last several years have been a landmark period in the ubiquitin field. The breadth of ubiquitin's roles in cell biology was first sketched, and the importance of ubiquitin-dependent proteolysis as a regulatory mechanism gained general acceptance. The many strands of work that led to this new perception are re counted in this book. A consequence of this progress is that the field has grown dramatically since the first book on ubiquitin was published almost a decade ago [M. Rechsteiner (ed. ), Ubiquitin, Plenum Press, 1988]. In this span, students of the cell cycle, transcription, signal transduction, protein sorting, neuropathology, cancer, virology, and immunology have attempted to chart the role of ubi quit in in their particular experimental systems, and this integration of the field into cell biology as a whole continues at a remarkable pace. We hope that for active researchers in the field as well as for newcomers and those on the fence, this book will prove helpful for its breadth, historical perspective, and practical tips. Structural data are now available on many of the components of the ubiquitin pathway. The structures have provided basic insights into the unusual biochemical mechanisms of ubiquitination and proteasome-mediated proteolysis. Because high-speed computer graphics can convey structures more effectively than print media, we have supplemented the figures of the book with a Worldwide Web site that can display the structures in a flexible, viewer-controlled format.
Download or read book Autophagy Cancer Other Pathologies Inflammation Immunity Infection and Aging written by M. A. Hayat and published by Academic Press. This book was released on 2016-12-28 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autophagy: Cancer, Other Pathologies, Inflammation, Immunity, Infection, and Aging is an eleven volume series that discusses in detail all aspects of autophagy machinery in the context of health, cancer, and other pathologies. Autophagy maintains homeostasis during starvation or stress conditions by balancing the synthesis of cellular components and their deregulation by autophagy. This series discusses the characterization of autophagosome-enriched vaccines and its efficacy in cancer immunotherapy. Autophagy serves to maintain healthy cells, tissues, and organs, but also promotes cancer survival and growth of established tumors. Impaired or deregulated autophagy can also contribute to disease pathogenesis. Understanding the importance and necessity of the role of autophagy in health and disease is vital for the studies of cancer, aging, neurodegeneration, immunology, and infectious diseases. Comprehensive and forward-thinking, these books offer a valuable guide to cellular processes while also inciting researchers to explore their potentially important connections. Presents the most advanced information regarding the role of the autophagic system in life and death Examines whether autophagy acts fundamentally as a cell survivor or cell death pathway or both Introduces new, more effective therapeutic strategies in the development of targeted drugs and programmed cell death, providing information that will aid in preventing detrimental inflammation Features recent advancements in the molecular mechanisms underlying a large number of genetic and epigenetic diseases and abnormalities, including atherosclerosis and CNS tumors, and their development and treatment Includes chapters authored by leaders in the field around the globe—the broadest, most expert coverage available
