Human Tumor-Derived p53 Mutants: A Growing Family of Oncoproteins by Ygal Haupt,Giovanni Blandino Pdf

TP53 gene mutations are present in more than half of all human cancers. The resulting proteins are mostly full-length with a single amino acid change and are abundantly expressed in cancer cells. Some of the mutant p53 proteins gain oncogenic functions (GOF) through which it actively contribute to the aberrant cell proliferation, increased resistance to apoptotic stimuli and ability to metastasize. Gain of function mutant p53 proteins can transcriptionally regulate the expression of a large plethora of target genes. This mainly occurs through the formation of oncogenic transcriptional competent complexes that include mutant p53 protein, known transcription factors, posttranslational modifiers and scaffold proteins. Mutant p53 protein can also transcriptionally regulate the expression of microRNAs, small non-coding RNAs that regulate gene expression at the posttranscriptional level. Each microRNA can putatively target the expression of hundred mRNAs and consequently impact on many cellular functions. Thus, gain of function mutant p53 proteins can exert their oncogenic activities through the modulation of both non-coding and coding regions of human genome. Over the past 3 decades, the regulation of p53 has been extensively studied. However, the regulation of mutant p53 remained largely unexplored. This snapshot focuses on recent discovery of mutant p53 GOF and regulation.

Apoptosis and Cancer by Seamus J. Martin Pdf

The past five years have witnessed an explosion of research efforts in the study of how cells die. This book provides an up-to-date overview of our current knowledge of apoptosis and how discoveries in this area impact on our understanding of cancer. By synthesizing many of the recent developments in this area and placing them in perspective, it fulfills an important need. All the contributions are written by experts in their respective fields. The first two chapters give a basic introduction to the cell death machinery and its role in tumor development and progression; subsequent chapters cover current aspects of apoptosis research, including the involvement of cell cycle-related proteins (e.g. cyclin-dependent kinases) in apoptosis, the role of Bcl-2, Bcr-Abl, Rb, p53 and myc in the regulation of cell death, and apoptosis in the context of specific neoplasms such as cancer of the prostate, kidney, leukemia and neuroblastoma. It is also discussed how insights into the regulation of apoptosis may be exploited for designing new drugs aimed at eliminating malignant cells. Compiling the most recent research results on the relationship between apoptosis and cancer in one handy volume, this book will provide a valuable reference for scientists working in cancer research as well as newcomers to the field.

How Tobacco Smoke Causes Disease by Anonim Pdf

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Signal Transduction in Cancer by David A. Frank Pdf

One of the most exciting areas of cancer research now is the development of agents which can target signal transduction pathways that are activated inappropriately in malignant cells. The understanding of the molecular abnormalities which distinguish malignant cells from their normal counterparts has grown tremendously. This volume summarizes the current research on the role that signal transduction pathways play in the pathogenesis of cancer and how this knowledge may be used to develop the next generation of more effective and less toxic anticancer agents. Series Editor comments: "The biologic behavior of both normal and cancer cells is determined by critical signal transduction pathways. This text provides a comprehensive review of the field. Leading investigators discuss key molecules that may prove to be important diagnostic and/or therapeutic targets."

Heat Shock Proteins in Cancer by Stuart K. Calderwood,Michael Y. Sherman,Daniel R. Ciocca Pdf

Heat shock proteins are emerging as important molecules in the development of cancer and as key targets in cancer therapy. These proteins enhance the growth of cancer cells and protect tumors from treatments such as drugs or surgery. However, new drugs have recently been developed particularly those targeting heat shock protein 90. As heat shock protein 90 functions to stabilize many of the oncogenes and growth promoting proteins in cancer cells, such drugs have broad specificity in many types of cancer cell and offer the possibility of evading the development of resistance through point mutation or use of compensatory pathways. Heat shock proteins have a further property that makes them tempting targets in cancer immunotherapy. These proteins have the ability to induce an inflammatory response when released in tumors and to carry tumor antigens to antigen presenting cells. They have thus become important components of anticancer vaccines. Overall, heat shock proteins are important new targets in molecular cancer therapy and can be approached in a number of contrasting approaches to therapy.

Autophagy and Cancer by Hong-Gang Wang Pdf

With the explosion of information on autophagy in cancer, this is an opportune time to speed the efforts to translate our current knowledge about autophagy regulation into better understanding of its role in cancer. This book will cover the latest advances in this area from the basics, such as the molecular machinery for autophagy induction and regulation, up to the current areas of interest such as modulation of autophagy and drug discovery for cancer prevention and treatment. The text will include an explanation on how autophagy can function in both oncogenesis and tumor suppression and a description of its function in tumor development and tumor suppression through its roles in cell survival, cell death, cell growth as well as its influences on inflammation, immunity, DNA damage, oxidative stress, tumor microenvironment, etc. The remaining chapters will cover topics on autophagy and cancer therapy. These pages will serve as a description on how the pro-survival function of autophagy may help cancer cells resist chemotherapy and radiation treatment as well as how the pro-death functions of autophagy may enhance cell death in response to cancer therapy, and how to target autophagy for cancer prevention and therapy − what to target and how to target it. ​

Mutant p53 and MDM2 in Cancer by Swati Palit Deb,Sumitra Deb Pdf

This book provides the readers with an overview of research on p53, which has been shown to play a role in numerous crucial biological pathways in normal and cancer cells. Leading scientist in the field, who have all made direct contributions to the understanding of the molecular events underpinning p53 function, have been invited to contribute the various chapters, which discuss the current knowledge of the signaling cascades that are activated by mutations in p53 and overexpression of MDM2, frequently found in human cancer and are major causes of oncogenesis. This book features chapters on the molecular basis of oncogenesis induced by gain of function mutation of p53, signaling pathways induced by MDM2 overexpression, control of mutant or wild-type p53 function by MDM2 and MDMX, p53 mutation in hereditary cancer and structural aspects that activate mutant p53 which can be targeted by drug therapy. This book should be useful for scientists at all levels.
