Polyamine Cell Signaling


Book Description

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.




Regulation of Gastrointestinal Mucosal Growth


Book Description

The mammalian gastrointestinal mucosa is a rapidly self-renewing tissue in the body, and its homeostasis is preserved through the strict regulation of epithelial cell proliferation, growth arrest, and apoptosis. The control of the growth of gastrointestinal mucosa is unique and, compared with most other tissue in the body, complex. Mucosal growth is regulated by the same hormones that alter metabolism in other tissues, but the gastrointestinal mucosa also responds to host events triggered by the ingestion and presence of food within the digestive tract. These gut hormones and peptides regulate the growth of the exocrine pancreas, gallbladder epithelium, and the mucosa of the oxyntic gland region of the stomach and the small and large intestines. Luminal factors, including nutrients or other dietary factors, secretions, and microbes that occur within the lumen and distribute over a proximal-to-distal gradient, are also crucial for maintenance of normal gut mucosal regeneration and could explain the villous-height-crypt-depth gradient and variety of adaptation, since these factors are diluted, absorbed, and destroyed as they pass down the digestive tract. Recently, intestinal stem cells, cellular polyamines, and noncoding RNAs are shown to play an important role in the regulation of gastrointestinal mucosal growth under physiological and various pathological conditions. In this book, we highlight key issues and factors that control gastrointestinal mucosal growth and homeostasis, with special emphasis on the mechanisms through which epithelial renewal and apoptosis are regulated at the cellular and molecular levels.




Protective Chemical Agents in the Amelioration of Plant Abiotic Stress


Book Description

A guide to the chemical agents that protect plants from various environmental stressors Protective Chemical Agents in the Amelioration of Plant Abiotic Stress offers a guide to the diverse chemical agents that have the potential to mitigate different forms of abiotic stresses in plants. Edited by two experts on the topic, the book explores the role of novel chemicals and shows how using such unique chemical agents can tackle the oxidative damages caused by environmental stresses. Exogenous application of different chemical agents or chemical priming of seeds presents opportunities for crop stress management. The use of chemical compounds as protective agents has been found to improve plant tolerance significantly in various crop and non-crop species against a range of different individually applied abiotic stresses by regulating the endogenous levels of the protective agents within plants. This important book: Explores the efficacy of various chemical agents to eliminate abiotic stress Offers a groundbreaking look at the topic and reviews the most recent advances in the field Includes information from noted authorities on the subject Promises to benefit agriculture under stress conditions at the ground level Written for researchers, academicians, and scientists, Protective Chemical Agents in the Amelioration of Plant Abiotic Stress details the wide range of protective chemical agents, their applications, and their intricate biochemical and molecular mechanism of action within the plant systems during adverse situations.




The Genus Yersinia:


Book Description

The 9th International Symposium on Yersinia was held in Lexington, Kentucky, USA on October 10-14, 2006. Over 250 Yersinia researchers from 18 countries gathered to present and discuss their research. In addition to 37 oral presentations, there were 150 poster presentations. This Symposium volume is based on selected presentations from the meeting and contains both reviews and research articles. It is divided into six topic areas: 1) genomics; 2) structure and metabolism; 3) regulatory mechanisms; 4) pathogenesis and host interactions; 5) molecular epidemiology and detection; and 6) vaccine and antimicrobial therapy development. Consequently, this volume covers a wide range of current research areas in the Yersinia field.




Annual Plant Reviews, The Plant Hormone Ethylene


Book Description

The plant hormone ethylene is one of the most important, being one of the first chemicals to be determined as a naturally-occurring growth regulator and influencer of plant development. It was also the first hormone for which significant evidence was found for the presence of receptors. This important new volume in Annual Plant Reviews is broadly divided into three parts. The first part covers the biosynthesis of ethylene and includes chapters on S-adenosylmethionine and the formation and fate of ACC in plant cells. The second part of the volume covers ethylene signaling, including the perception of ethylene by plant cells, CTR proteins, MAP kinases and EIN2 / EIN3. The final part covers the control by ethylene of cell function and development, including seed development, germination, plant growth, cell separation, fruit ripening, senescent processes, and plant-pathogen interactions. The Plant Hormone Ethylene is an extremely valuable addition to Wiley-Blackwell's Annual Plant Reviews. With contributions from many of the world's leading researchers in ethylene, and edited by Professor Michael McManus of Massey University, this volume will be of great use and interest to a wide range of plant scientists, biochemists and chemists. All universities and research establishments where plant sciences, biochemistry, chemistry, life sciences and agriculture are studied and taught should have access to this important volume.
