Available in PDF, EPUB and Kindle. Book excerpt: Polyamines are organic cations found in all eukaryotic cells and intimately involved in, and required for, distinct biological functions. An increasing body of evidence indicates that the regulation of cellular polyamines is a central convergence point for the multiple signaling pathways driving various cellular functions. Over the last decade, considerable progress has been made in und- standing the molecular functions of cellular polyamines. These significant findings provide a fundamental basis to not only define the exact role of polyamines in physiology, but also to develop new therapeutic approaches for cancers and other diseases. The major objective of this book is to provide a timely and long lasting guide for investigators in the fields of polyamines, physiology, pharmacology, and cancer research. It will provide a foundation based on research and address the potential for subsequent applications in clinical practice. Polyamine Cell Signaling: Physiology, Pharmacology, and Cancer Research is divided into four main parts: Part I: Polyamines in Signal Transduction of Cell Proliferation Part II: Polyamines in Cellular Signaling of Apoptosis, Carcinogenesis, and Cancer Therapy Part III: Polyamines in Cell Motility and Cell–Cell Interactions Part IV: Polyamine Homeostasis and Transport This book not only covers the current state-of-the-art findings relevant to cellular and molecular functions of polyamines, but also provides the underlying conceptual basis and knowledge regarding potential therapeutic targeting of polyamines and polyamine metabolism. These points are addressed by int- nationally recognized experts in their contributions to this book.

Download or read book Polyamine Metabolism in Disease and Polyamine Targeted Therapies written by Tracy Murray-Stewart and published by MDPI. This book was released on 2019-10-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyamines are ubiquitous polycations essential for all cellular life. The most common polyamines in eukaryotes, spermine, spermidine, and putrescine, exist in millimolar intracellular concentrations that are tightly regulated through biosynthesis, catabolism, and transport. Polyamines interact with, and regulate, negatively charged macromolecules, including nucleic acids, proteins, and ion channels. Accordingly, alterations in polyamine metabolism affect cellular proliferation and survival through changes in gene expression and transcription, translation, autophagy, oxidative stress, and apoptosis. Dysregulation of these multifaceted polyamine functions contribute to multiple disease processes, thus their metabolism and function have been targeted for preventive or therapeutic intervention. The correlation between elevated polyamine levels and cancer is well established, and ornithine decarboxylase, the rate-limiting biosynthetic enzyme in the production of putrescine, is a bona fide transcriptional target of the Myc oncogene. Furthermore, induced polyamine catabolism contributes to carcinogenesis that is associated with certain forms of chronic infection and/or inflammation through the production of reactive oxygen species. These and other characteristics specific to cancer cells have led to the development of polyamine-based agents and inhibitors aimed at exploiting the polyamine metabolic pathway for chemotherapeutic and chemopreventive benefit. In addition to cancer, polyamines are involved in the pathologies of neurodegenerative diseases including Alzheimer’s and Parkinson’s, parasitic and infectious diseases, wound healing, ischemia/reperfusion injuries, and certain age-related conditions, as polyamines are known to decrease with age. As in cancer, polyamine-based therapies for these conditions are an area of active investigation. With recent advances in immunotherapy, interest has increased regarding polyamine-associated modulation of immune responses, as well as potential immunoregulation of polyamine metabolism, the results of which could have relevance to multiple disease processes. The goal of this Special Issue of Medical Sciences is to present the most recent advances in polyamine research as it relates to health, disease, and/or therapy.

Download or read book Polyamines written by Tomonobu Kusano and published by Springer. This book was released on 2015-01-07 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers key topics in polyamine research from a range of organisms, including plants, mammals, and prokaryotes such as bacteria and archaea. The book provides an introduction to general concepts in the field of polyamine research, as well as more detailed information. With the availability of genome sequence data from a broad range of organisms, the evolution of the genes involved in polyamine metabolism is discussed. The mode of action of polyamines has been shown to be dependent on cation channels, and this mechanism is described in the book. The origin of polyamine transporters (from bacteria, yeasts, and plants) is described. The various effects of polyamines on growth and survival are also documented. The book details the mechanisms of polyamine homeostasis and the role of polyamine molecules as precursors of secondary metabolites such as plant alkaloids and toxins derived from spiders and wasps. The role of polyamines in longevity and disease is discussed. A link between polyamine contents and cancer progression is reported, as is the use of polyamine metabolites as diagnostic markers in the initial stages of cancer. Moreover, a novel approach that utilizes the polyamine pathway of a parasite as a drug target in African sleeping sickness is described. Therefore, this book is a valuable resource, both as a textbook for undergraduate and graduate students and also as a reference book for front-line polyamine researchers.

Available in PDF, EPUB and Kindle. Book excerpt: The polyamines are ubiquitous and essential organic cations in prokaryotic and eukaryotic cells. This book is a comprehensive survey of the development of knowledge of their physiological and structural roles. Currently, the genetic and regulatory determinants of the amines and their cellular composition are being explored actively as parameters of normal physiology and aberrant pathologies. Cancer, virus infection, and protozoan parasitism are major examples of the later groups. Studies of the control of polyamine metabolism are providing important therapeutic leads. Further, the structural roles of the amines are being determined at molecular levels, contributing to the understanding of polynucleotide and protein organization and interaction, as well as to the solution of problems of genome transfer. These subjects describe a burgeoning biochemical area involving compounds whose roles in cytoplasmic and nuclear function include numerous aspects of organelle structure, polymer synthesis, and interactions.

Available in PDF, EPUB and Kindle. Book excerpt: Polyamines are ubiquitous molecules that are involved in a number of important cellular processes. Aberrations in their function or metabolism play a role in diseases such as cancer and parasitic infection. A number of validated drug targets have been identified, including enzymes in the polyamine biosynthetic and catabolic pathways and the S-adenosylmethionine synthetic and salvage pathways. Polyamine Drug Discovery is the first comprehensive volume to cover all aspects of the design and development of potential therapeutics targeting polyamine metabolism. The book details research progress from 1975 to the present date and discusses the design and use of polyamine metabolism inhibitors as therapeutic agents. Various polyamine-containing drugs are described that can be used in chemotherapy, and as treatments for infections including trypanosomiasis, leishmaniasis and malaria. Finally, the roles of polyamine analogues in chemoprevention, polyamine-containing vectors for gene delivery, and the design of polyamine-based epigenetic modulators are detailed. Each chapter addresses a different aspect of polyamine drug discovery and all are written by medicinal and biological chemists with particular expertise in developing agents that modulate polyamine metabolism or function. The book will increase the visibility of polyamine drug discovery among pharmaceutical researchers and provide a valuable reference for everyone working in the field.

Download or read book Progress in Polyamine Research written by V. Zappia and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the scientific contributions presented at an International Symposium held in Sorrento, Italy, in June 1988 under the auspices of the University of Naples, the Italian Society of Biochemistry, and the National Research Council. The modern history of polyamines dates back to 1958 when the Tabors and Rosenthal first described the outlines of their biological synthesis. From then on, and particularly in the last ten years, a veri table explosion of Literature, characterized by thousands of papers, has witnessed the interest of the scientific community toward these molecules. Perhaps the old statement that "polyamines are molecules in search of a function" is no longer true today. A large number of effects exerted by these simple molecules are well known, and in many cases the mechanisms underlying these effects have been elucidated. The first section of the volume is entirely devoted to the enzymology and molecular biology of ornithine decarboxylase. Since its discovery by Gale more than forty years ago, this can be considered among the most widely studied enzymes in biology, and one of the most complex models in enzyme regulation. The mechanism of control of the enzyme activity at the transcriptional, post-transcriptional and post-translational levels, as well as the fine regulation by antizyme, are discussed in detail. The second group of contributions deals wi th AdoMet decarboxylase, propylamine transferase, polyamine oxidase and the other enzymes related to polyamine interconversion and regeneration.

Download or read book Polyamine Analogues as Novel Anti HER Family Agents in Human Breast Cancer written by and published by . This book was released on 2009 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elevated levels of all three naturally occurring polyamines, spermine, spermidine and putrescine, have been found in breast cancer tissues. Polyamine analogues have been shown to inhibit cell growth and in some cases induce apoptosis. My studies have demonstrated the ability of Progen (PG)-11144 and other oligoamines to inhibit cell growth in human breast cancer cell lines. These oligoamines can also suppress epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2) and estrogen receptor(ER)-alpha protein in multiple human breast cancer cell lines. Low dose long term exposure of T47D cells to PG-11144 decreases heat shock protein (HSP) 90 in addition to several HER family member proteins while not decreasing other receptors such as vitamin D receptor (VDR) and retinoic acid receptor (RAR)-beta. In addition to T47D cells, RAR-beta protein levels were maintained in MCF7 cells treated with PG-11144. Oligoamines PG-11144 and PG-11150 inhibit the growth of MCF7 and T47D breast cancer cell lines in a time and dose dependent manner. This project demonstrates that polyamine analogues are novel anti-HER family agents and contributes to their cytotoxicity in human breast cancer cells.
Download or read book Polyamines in Health and Nutrition written by Susan Bardocz and published by Springer Science & Business Media. This book was released on 1999-06-30 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of polyamines for all living cells has been recognized since spermine was discovered in human semen more than 300 years ago. Polyamine research intensified when analytical methods were developed for their determination, particularly in tissues and biological fluids. Discovering their close correlation with cancer, and that polyamine concentrations change during the cell cycle, gave reason for further research in this topic. Polyamines in Health and Nutrition concentrates on the direction of polyamine research which has the capacity to influence and benefit our health and which can explain some of the discrepancies and failures of earlier research. It is important to recognize the dietary contribution to the polyamine body pool and to investigate how the polyamine content of the diet can be changed, with the ultimate aim of using this information to improve our health.
