Every cell in our bodies contains a great variety and number of permeability pathways for various organic and inorganic ions, water, metabolites, nutrients, and signalling molecules. Maintenance and precise control of gating within these pathways are fundamental principles of life as these underlie basic cellular functions such as communication, contractility, and metabolism. In Ion Channels: Methods and Protocols, Second Edition, experts in the field contribute chapters that focus on the strategies, approaches, methods, and protocols for studying a large family of proteins that form ionic channels in the plasma membrane and intracellular membranes of cells. Using practical examples from the cutting-edge current research, this volume will take a look back at the major methods and approaches that aided the progress toward the current understanding of ion channel function, structural design, and biological roles. The volume also aims to look forward and identify approaches that will lead us to future discoveries. Written in the highly successful Methods in Molecular Biology (TM) series format, 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 cutting-edge, Ion Channels: Methods and Protocols, Second Edition will greatly assist researchers searching for specific methodology in studying ion channels on the path toward a greater understanding of these key biological features.
The critically acclaimed laboratory standard for more than forty
years, Methods in Enzymology is one of the most highly respected
publications in the field of biochemistry. Since 1955, each volume
has been eagerly awaited, frequently consulted, and praised by
researchers and reviewers alike. More than 285 volumes have been
published (all of them still in print) and much of the material is
relevant even today-truly an essential publication for
researchersin all fields of life sciences.
Systems biology can now be considered an established and fundamental field in life sciences. It has moved from the identification of molecular 'parts lists' for living organisms towards synthesising information from different 'omics'-based approaches to generate and test new hypotheses about how biological systems work. In In Silico Systems Biology: Methods and Protocols, expert researchers in the field detail a practical set of chapters based often on actual materials used and develop for face-to-face training with examples and case studies. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, step-by-step workflows, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, In Silico Systems Biology: Methods and Protocols seeks to aid scientists in the further study of network biology and mathematical models of biological systems.

biological techniques.
The Endoplasmic Reticulum (ER) is an organelle with extraordinary signaling and homeostatic functions. It is the organelle responsible for protein folding, maturation, quality control and trafficking of proteins destined for the plasma membrane or for secretion into the extracellular environment. Failure, overloading or malfunctioning of any of the signaling or quality control mechanisms occurring in the ER may provoke a stress condition known as ER stress . Accumulating evidence indicates that ER stress may dramatically perturb interactions between the cell and its environment, and contribute to the development of human diseases, ranging from metabolic diseases and cancer to neurodegenerative diseases, or impact therapeutic outcome. This book primarily focuses on the pathophysiology of ER stress. It introduces the molecular bases of ER stress, the emerging relevance of the ER-mitochondria cross-talk, the signaling pathways engaged and cellular responses to ER stress, including the adaptive Unfolded Protein Response (UPR), autophagy as well as cell death. Next the book addresses the role of ER stress in physiology and in the etiology of relevant pathological conditions, like carcinogenesis and inflammation, neurodegeneration and metabolic disease. The last chapter describes how ER stress pathways can be targeted for therapeutic benefit. Altogether, this book will provide the reader with an exhaustive view of ER stress biology and the latest insights in the role of ER stress in relevant human diseases."
How do you keep track of basic information on the proteins you work
with? Where do you find details of their physicochemical
properties, amino acid sequences, and structure? Are you tired of
scanning review articles, primary papers, and databases to locate
that elusive fact?
Researchers in the field of ecological genomics aim to determine how a genome or a population of genomes interacts with its environment across ecological and evolutionary timescales. Ecological genomics is trans-disciplinary by nature. Ecologists have turned to genomics to be able to elucidate the mechanistic bases of the biodiversity their research tries to understand. Genomicists have turned to ecology in order to better explain the functional cellular and molecular variation they observed in their model organisms. We provide an advanced-level book that covers this recent research and proposes future development for this field. A synthesis of the field of ecological genomics emerges from this volume."Ecological Genomics"covers a wide array of organisms (microbes, plants and animals) in order to be able to identify central concepts that motivate and derive from recent investigations in different branches of the tree of life. "Ecological Genomics"covers 3 fields of research that have most benefited from the recent technological and conceptual developments in the field of ecological genomics: the study of life-history evolution and its impact of genome architectures; the study of the genomic bases of phenotypic plasticity and the study of the genomic bases of adaptation and speciation.

Gaining an understanding of the mechanisms by which cells process and respond to extracellular cues has become a major goal in many areas of bi- ogy and has attracted the attentions of almost every traditional discipline within the biological sciences. At the heart of these divergent endeavors are common methods that can aid biochemists, physiologists, and pharmacologists in ta- ling the specific questions addressed by their research. In Receptor Signal Transduction Protocols, a diverse array of meth- ologies employed to interrogate ligand--receptor and receptor-effector int- actions are described by authors who have devised and successfully applied them. The authors blend excellent descriptions and applications of fairly well established methodologies with new technologies at the cutting-edge of signal transduction research and as such I hope the present volume will complement and extend a previous excellent volume in this series edited by David Kendall and Stephen Hill (Methods Molecular Biology, vol. 41, Signal Transd- tion Protocols).
Protein informatics is a newer name for an already existing discipline. It encompasses the techniques used in bioinformatics and molecular modeling that are related to proteins. While bioinformatics is mainly concerned with the collection, organization, and analysis of biological data, molecular modeling is devoted to representation and manipulation of the structure of proteins. Protein informatics requires substantial prerequisites on computer science, mathematics, and molecular biology. The approach chosen here, allows a direct and rapid grasp on the subject starting from basic knowledge of algorithm design, calculus, linear algebra, and probability theory. An Introduction to Protein Informatics, a professional monograph will provide the reader a comprehensive introduction to the field of protein informatics. The text emphasizes mathematical and computational methods to tackle the central problems of alignment, phylogenetic reconstruction, and prediction and sampling of protein structure. An Introduction to Protein Informatics is designed for a professional audience, composed of researchers and practitioners within bioinformatics, molecular modeling, algorithm design, optimization, and pattern recognition. This book is also suitable as a graduate-level text for students in computer science, mathematics, and biomedicine.
Over the last decade the development of new molecular biology tools, advanced microscopy, live imaging and systems biology approaches have revolutionized our conception of how embryonic development proceeds. One fundamental aspect of development biology is the concept of morphogenesis: understanding how a group of multipotent cells organize and differentiate into a complex organ. In Kidney Development: Methods and Protocols, expert researchers in the field detail different approaches to tackle kidney development. These approaches include culture and live imaging aspects of kidney development, analyzing the 3-dimensional aspects of branching morphogenesis as well as nephrogenesis, manipulation of the gene/protein expression during kidney development as well as in the adult kidney, and how to assess kidney malformation and disease. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Kidney Development: Methods and Protocols seeks to aid scientists in the further study of the process of morphogenesis which is fundamental important not only for studying developmental biology but also for regenerative medicine.
During the course of evolution, an imbalance was created between the rate of vertebrate genetic adaptation and that of the lower forms of living organisms, such as bacteria and viruses. This imbalance has given the latter the advantage of generating, relatively quickly, molecules with unexpected structures and features that carry a threat to vertebrates. To compensate for their weakness, vertebrates have accelerated their own evolutionary processes, not at the level of whole organism, but in specialized cells containing the genes that code for antibody molecules or for T-cell receptors. That is, when an immediate requirement for molecules capable of specific interactions arose, nature has preferred to speed up the mode of Darwinian evolution in pref- ence to any other approach (such as the use of X-ray diffraction studies and computergraphic analysis). Recently, Darwinian rules have been adapted for test tube research, and the concept of selecting molecules having particular characteristics from r- dom pools has been realized in the form of various chemical and biological combinatorial libraries. While working with these libraries, we noticed the interesting fact that when combinatorial libraries of oligopeptides were allowed to interact with different selector proteins, only the actual binding sites of these proteins showed binding properties, whereas the rest of the p- tein surface seemed "inert. " This seemingly common feature of protein- having no extra potential binding sites--was probably selected during evolution in order to minimize nonspecific interactions with the surrounding milieu.
Volume 2 has focused on aspects of the pituitary gland both
anterior (growth hormone and prolactin receptors, and GH action)
and posterior (vasopressin) pituitary. In addition, thyroid cancer
and steroidogenic enzymes and precocious puberty are covered.
Finally, the "hot topics" include leptin and growth factor
signaling.
From basic performing of sequence alignment through a proficiency at understanding how most industry-standard alignment algorithms achieve their results, "Multiple Sequence Alignment Methods" describes numerous algorithms and their nuances in chapters written by the experts who developed these algorithms. The various multiple sequence alignment algorithms presented in this handbook give a flavor of the broad range of choices available for multiple sequence alignment generation, and their diversity is a clear reflection of the complexity of the multiple sequence alignment problem and the amount of information that can be obtained from multiple sequence alignments. Each of these chapters not only describes the algorithm it covers but also presents instructions and tips on using their implementation, as is fitting with its inclusion in the highly successful "Methods in Molecular Biology" series. Authoritative and practical, "Multiple Sequence Alignment Methods" provides a readily available resource which will allow practitioners to experiment with different algorithms and find the particular algorithm that is of most use in their application."
Molecular modeling has undergone a remarkable transformation in the last 20 years. This book provides thorough introductions and a compilation of step-by-step methods applicable to problems faced by non-specialists especially those new to the software packages used in molecular modeling. Tips on troubleshooting and avoiding common pitfalls are included in the book, along with chapters covering a wide range of subjects. Links to downloadable software are also provided.
A large number of newly-synthesized polypeptides must cross one or
several intracellular membranes to reach their functional locations
in the eukaryotic cell. The mechanisms of protein trafficking, in
particular the post-translational targeting and membrane
translocation of proteins, are of fundamental biological importance
and are the focus of intensive research world-wide. For more than
15 years, mitochondria have served as the paradigm organelle system
to study these processes. Although key questions, such as how
precisely proteins cross a membrane, still remain to be answered,
exciting progress has been made in understanding the basic pathways
of protein import into mitochondria and the components involved. In
addition to a fascinating richness and complexity in detail, the
analysis of mitochondrial protein import has revealed mechanistic
principles of general significance: Major discoveries include the
demonstration of the requirement of an unfolded state for
translocation and of the essential role of molecular chaperones on
both sides of the membranes in maintaining a
translocation-competent conformation and in protein folding after
import. It is becoming clear how a polypeptide chain is "reeled"
across the membrane in an ATP-dependent process by the functional
cooperation of membrane proteins, presumably constituting part of a
transmembrane channel, with peripheral components at the trans-side
of the membrane.
The field of DNA repair is vast and advancing rapidly. Recent investigations have begun to focus on the involvement of chromatin in the repair of broken DNA. Although I have no doubt that many breakthroughs in our understanding of chromatin, chromatin regulation, and DNA repair lie in our future, presently this is a new line in inquiry. As such there are many, many unanswered questions. Indeed, most of the correct questions have probably not even been asked yet. Here I have attempted to present a review of some of the current body of knowledge that may prove relevant to understanding the role of chromatin in DNA repair. Because the volume of research, and the relevant findings, come from a staggering array of labs, systems, and ideas I have focused primarily on findings developed from the study of the budding yeast Saccharomyces cerevisiae. Unfortunately, this means that I have left out a great deal of information. It is my hope, however, that the information I do detail, particularly in Chapter 1, will give a flavor for the scope of the problem and perhaps highlight some of the interesting directions this field is taking, or may one day take. I would also point out that the primary research that is presented herein is not in any way meant to represent the comprehensive scope of research being performed. To understand DNA repair will require investigation from innumerable labs, performed by innumerable researchers, moving in unexpected directions.
This informative publication brings together knowledge of various
aspects of cellular regulation. Current Topics in Cellular
Regulation reviews the progress being made in those specialized
areas of study that have undergone substantial development. It also
publishes provocative new theories and concepts and serves as a
forum for the discussion of general principles. Researchers in
cellular regulation as well as biochemists, molecular and cell
biologists, microbiologists, and biophysicists will find Current
Topics in Cellular Regulation a useful source of up-to-date
information.
It is now clear from a wide range of research that cytoplasm is not
merely a buffered solution of proteins and enzymes but contains a
series of complex filamentous structures. The cytoskeleton is the
collective term given to these filaments. There is a considerable
amount of data available on the protein composition of the major
filament systems (microfilaments, microtubules, and intermediate
filaments) but we are still comparatively ignorant about the role
of the cytoskeleton in cell physiology. However such major
cytoplasmic components (actin and tubulin, the monomeric
constituents of microfilaments and microtubules, are major cell
proteins) must have important roles to play in cell function, and
investigations into the functional role of the cytoskeleton
currently represent a major area of cell biological research.
Drawing especially on insights emerging from studies of the cellular networks formed by fungi, this book describes the fundamental indeterminacy that enables life forms to thrive in and create inconstant circumstances. It explains how indeterminacy arises from counteraction between associative and dissociative processes at the reactive interfaces between living systems and their surroundings. It stresses the relevance of these processes to understanding the dynamic contexts within which living systems of all kinds - including human societies-explore for, use up, conserve and recycle sources of energy.By focusing on dynamic boundaries, the book counterbalances the discretist view that living systems are assembled entirely from building-block-like units - individuals and genes - that can be freely sifted, as opposed to channeled, by natural selection. It also shows how the versatility that enables life forms to proliferate in rich environments, whilst minimizing losses in restrictive environments, depends on capacities for error and co-operation within a fluid, non-hierarchical power structure. Understanding this point yields a more compassionate, less competitive and less self-centred outlook on life's successes and failures.

Posttranslational Modifications of Proteins: Tools for Functional Proteomics is a compilation of detailed protocols needed to detect and analyze the most important co- and posttranslational modifications of proteins. Though, for reasons of simplicity not explicitly mentioned in the title, both kinds of modifications are covered, whether they occur during, or after, biosynthesis of the protein. My intention was to cover the most significant protein modifications, focusing on the fields of protein function, proteome research, and the characterization of pharmaceutical proteins. The majority of all proteins undergo co- and/or posttranslational modifications. Knowledge of these modifications is extremely important, since they may alter physical and chemical properties, folding, conformation distribution, stability, act- ity, and, consequently, function of the proteins. Moreover, the modification itself can act as an added functional group. Examples of the biological effects of protein mo- fications include: phosphorylation for signal transduction, ubiquitination for p- teolysis, attachment of fatty acids for membrane anchoring or association, glycosylation for protein half-life, targeting, cell-cell and cell-matrix interactions, and carboxylation in protein-ligand binding to name just a few. Full understanding of a specific protein structure-function relationship requires detailed information not only on its amino acid sequence, which is determined by the corresponding DNA sequence, but also on the presence and structure of protein modifications.
This important volume is mainly concerned with the development of methods for "sequencing" - that is, determination of the order of the amino acids in proteins and of nucleotides in RNA and DNA. In 1943 the position of only one amino acid in a protein (insulin) was known, and Sanger's first paper resulted in finding a second amino acid. In his final paper in 1982 he describes the determination of a DNA sequence of 48,502 nucleotides. The papers describe the steady improvements in techniques, and exciting biological results revealed by the sequences.
Recombinant Proteins from Plants is one of the most exciting and fastest developing areas in biology. The latest molecular techniques are being applied to the exploitation of plants as novel expression systems for the p- duction and overproduction of heterologous and native proteins. Transgenic plant technology is currently used in three broad areas: the expression of - combinant proteins to improve crop quality by increasing disease/pest res- tance or increasing tolerance to stress, optimizing plant productivity and yield by the genetic manipulation of metabolic pathways, and the large-scale co- effective production of recombinant proteins for use as specialist industrial or therapeutic biomolecules. The intention of Recombinant Proteins from Plants is to provide c- prehensive and detailed protocols covering all the latest molecular approaches. Because the production oftransgenic plants has become routine in many la- ratories, coverage is also given to some of the more "classical" approaches to the separation, analysis, and characterization of recombinant proteins. The book also includes areas of research that we believe will become increasingly important in the near future: efficient transformation of monocots with Agrobacterium optimizing the stability of recombinant proteins, and a section highlighting the immunotherapeutic potential of plant-expressed proteins.
In the most recent years, each of the RNA silencing pathways of plants have appeared to generate ncRNAs with dedicated functions, specialized biological activities and specific functional scopes. RNA silencing plays a crucial role in coordinating the expression, stability, protection and inheritance of eukaryotic genomes. It compromises several mechanisms, that invariably depend on core small non coding RNAs and that achieve dedicated sequence-specific functions. RNA silencing has been recognized to carry critical developmental, stress-response and bodyguard functions be coordinating the expression, protection, stability and inheritance of virtually all eukaryotic genomes. Thus, the ncRNAs encompass a wide set of mechanisms that achieve specialized functions. |
