RNA Metabolism in Trypanosomes


Book Description

Trypanosomes are unicellular protozoa of ancient evolutionary origin that are responsible for several tropical diseases, such as African sleeping sickness. Over the last few decades, research in trypanosome biology has revealed many unique and fascinating features, many of which have helped to establish new paradigms in other biological systems. This applies in particular to studies in gene expression and regulation, which benefit enormously from the trypanosome genome projects and from the new genome-wide approaches recently introduced in trypanosome research. This volume covers the most important aspects of biosynthesis, processing, and functions of RNA in trypanosomes, ranging from transcription to RNA editing, mRNA splicing/translation/turnover, processing of transfer and ribosomal RNA, RNA interference, and current transcriptome-wide analyses. Recent progress in RNA-focused research in trypanosomatids promises to yield novel insights into trypanosome-specific features, as well as to reveal in the process new potential therapeutic strategies for combating these parasitic diseases.




RNA Editing


Book Description

Goringer’s brilliant new work dedicates a chapter to each of the main types of RNA editing – the very first volume to do so. All of the sections here have been written by experts in the various research areas and a specific focus is put on the correlation between RNA structure and function, as well as on the complex cellular machineries that catalyze the different editing reactions. This leads to a "state of the art" compendium of our current knowledge on RNA editing.




Proteins and Proteomics of Leishmania and Trypanosoma


Book Description

This book contains a collection of critical reviews on the expression of biologically functional proteins in Leishmania and Trypanosoma, which was written by renowned researchers on this field. Species belonging to these trypanosomatids’ genera are etiological agents of leishmaniasis, Chagas’ disease and sleeping sickness that are extremely debilitating human infection diseases, which remain a major health problem especially in countries from Latin America, Africa and Middle East. Substantiating the problem, the currently accepted drugs for these diseases are quiet unsatisfying due to their low efficacy and high toxicity. In order to solve these real problems, several research groups around the world have become involved in the study and identification of novel potential targets in the trypanosomatid cell. Since proteins are key macromolecules involved in crucial metabolic processes of all living cells, studies have focused on the expression of specific proteins produced by Leishmania and Trypanosoma by means of different biochemical, molecular and proteomic approaches in order to explore them as targets for understanding the parasite life cycle and developing new strategies against trypanosomiasis. With these proposals in mind, the book “Proteins and Proteomics of Leishmania and Trypanosoma” encompasses (i) an integrated view about the biochemistry of parasites belonging to the Leishmania and Trypanosoma genera; (ii) an updated review on the expression of biologically relevant proteins by human pathogenic trypanosomatids and their possible role in the interaction with host cells/molecules as well as a target for development of both alternative chemotherapies and vaccine; and (iii) several pictures, diagrams and tables that can be used to illustrate both undergraduate and postgraduate teaching as well as scientific lectures, being a useful resource for students and researchers.







Biochemistry and Molecular Biology of Parasites


Book Description

The study of parasitic organisms at the molecular level has yielded fascinating new insights of great medical, social, and economical importance, and has pointed the way for the treatment and prevention of the diseases they cause. Biochemistry and Molecular Biology of Parasites presents an up-to-date account of this modern scientific discipline in a manner that allows and encourages the reader to place the biochemistry and molecular biology of these organisms in their biological context. The chapters are cross-referenced and grouped in an arrangement that provides a fully integrated whole, and permits the reader to create a composite of the biochemical function of these organisms.Individual chapter includes those devoted to metabolism, in both aerobic and anaerobic protozoa; antioxidant mechanisms; parasite surfaces; organelles; invasion mechanisms; and chemotherapy. The helminths are discussed not only from the point of view of their cellular biochemistry and metabolism, but also with respect to both their integrated functions such as neurochemistry, structure and functions of surfaces, and reproduction. Written by expert investigators, this book will be of interest to all experienced researchers, graduate students, and to the newcomer eager to become familiar with the biochemistry and molecular biology of parasites.




Handbook of RNA Biochemistry

The second edition of a highly acclaimed handbook and ready reference. Unmatched in its breadth and quality, around 100 specialists from all over the world share their up-to-date expertise and experiences, including hundreds of protocols, complete with explanations, and hitherto unpublished troubleshooting hints. They cover all modern techniques for the handling, analysis and modification of RNAs and their complexes with proteins. Throughout, they bear the practising bench scientist in mind, providing quick and reliable access to a plethora of solutions for practical questions of RNA research, ranging from simple to highly complex. This broad scope allows the treatment of specialized methods side by side with basic biochemical techniques, making the book a real treasure trove for every researcher experimenting with RNA.




Post-Transcriptional Gene Regulation


Book Description

This volume presents the most recent advances in techniques for studying the post-transcriptional regulation of gene expression (PTR). With sections on bioinformatics approaches, expression profiling, the protein and RNA interactome, the mRNA lifecycle, and RNA modifications, the book guides molecular biologists toward harnessing the power of this new generation of techniques, while also introducing the data analysis skills that these high-throughput techniques require. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, Post-Transcriptional Gene Regulation, Third Edition serves as a versatile resource for researchers studying post-transcriptional regulation by both introducing the most recent techniques and providing a comprehensive guide to their implementation. Chapter 6 is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.




Systematics and the Exploration of Life


Book Description

This book's aim is to obtain and organize knowledge about the diversity of living things. Their epistomological and methodological fundamentals are explained in the framework of the biology of evolution. The methods of construction and use of phylogenetic trees are presented as well as the classification and description of taxa with the nomenclature rules.







Mitochondria and Anaerobic Energy Metabolism in Eukaryotes


Book Description

Mitochondria are sometimes called the powerhouses of eukaryotic cells, because mitochondria are the site of ATP synthesis in the cell. ATP is the universal energy currency, it provides the power that runs all other life processes. Humans need oxygen to survive because of ATP synthesis in mitochondria. The sugars from our diet are converted to carbon dioxide in mitochondria in a process that requires oxygen. Just like a fire needs oxygen to burn, our mitochondria need oxygen to make ATP. From textbooks and popular literature one can easily get the impression that all mitochondria require oxygen. But that is not the case. There are many groups of organismsm known that make ATP in mitochondria without the help of oxygen. They have preserved biochemical relicts from the early evolution of eukaryotic cells, which took place during times in Earth history when there was hardly any oxygen avaiable, certainly not enough to breathe. How the anaerobic forms of mitochondria work, in which organisms they occur, and how the eukaryotic anaerobes that possess them fit into the larger picture of rising atmospheric oxygen during Earth history are the topic of this book.
