R5,981 Discovery Miles 59 810 Ships in 10 - 15 working days

This book summarizes present knowledge of different mechanisms involved in the development of positive and negative consequences of cardiac adaptation. Particular attention is paid to the still underestimated adaptive cardiac responses during development, to adaptation to the frequently occurring pressure and volume overload as well as to cardiac changes, induced by enduring exercise and chronic hypoxia. Cardiac Adaptations will be of great value to cardiovascular investigators, who will find this book highly useful in their cardiovascular studies for finding solutions in diverse pathological conditions; it will also appeal to students, fellows, scientists, and clinicians interested in cardiovascular abnormalities.

SCF and APC E3 Ubiquitin Ligases in Tumorigenesis (Paperback, 2014 ed.): Hiroyuki Inuzuka, Wenyi Wei SCF and APC E3 Ubiquitin Ligases in Tumorigenesis (Paperback, 2014 ed.)
Hiroyuki Inuzuka, Wenyi Wei
R1,964 Discovery Miles 19 640 Ships in 10 - 15 working days

This SpringerBrief explores the physiological roles of Skp1-Cullin1-F-box Complex (SCF) and Anaphase Promoting Complex (APC) in normal cells and in tumor formation. These two related, multi-subunit E3 ubiquitin ligase enzymes, APC and SCF are thought to be the major driving forces governing proper cell cycle progression. Defective cell cycle regulation leads to genomic instability and ultimately, cancer development. Selective degradation of key cell cycle regulators by the ubiquitin-proteasome system has been proven to be a major regulatory mechanism for ensuring ordered and coordinated cell cycle progression. The SCF and APC E3 ligases have been characterized to play pivotal roles in regulating the cell cycle progression by timely degrading various critical cell cycle regulators. This Brief reviews recent studies that have shown that deregulation of signaling pathways in which the two ubiquitin ligases are involved causes aberrant cell cycle regulation, in turn leading to tumorigenesis. The text also discusses how SCF and APC may present promising therapeutic targets to treat various cancers.

Biophysical approaches to translational control of gene expression (Paperback, 2013 ed.): Jonathan D. Dinman Biophysical approaches to translational control of gene expression (Paperback, 2013 ed.)
Jonathan D. Dinman
R5,521 Discovery Miles 55 210 Ships in 10 - 15 working days

This book provides a premier resource on understanding the ribosome's essential nature and how it interacts with other proteins and nucleic acids to control protein synthesis. As one of the central foundations in our understanding of the biology at the molecular level, this topic appeals to a wide audience, from bench researcher to clinician. With the advent of atomic scale structures, methods to visualize and separate individual molecules, and the computational power to model the complex interactions of over a million atoms at once, our understanding of how gene expression is controlled at the level of protein translation is now deeply ensconced in the biophysical realm.

Receptor-like Kinases in Plants - From Development to Defense (Paperback, 2012 ed.): Frans Tax, Birgit Kemmerling Receptor-like Kinases in Plants - From Development to Defense (Paperback, 2012 ed.)
Frans Tax, Birgit Kemmerling
R4,582 Discovery Miles 45 820 Ships in 10 - 15 working days

Sequencing projects have revealed the presence of at least several hundred receptor kinases in a typical plant genome. Receptor kinases are therefore the largest family of primary signal transducers in plants, and their abundance suggests an immense signaling network that we have only just begun to uncover. Recent research findings indicate that individual receptor kinases fulfill important roles in growth and development, in the recognition of pathogens and symbionts or, in a few examples, in both growth and defense. This volume will focus on the roles of receptor kinases, their signaling pathways, and the ways in which these important signaling proteins are regulated.

Farid Rahimi, Gal Bitan
R5,953 Discovery Miles 59 530 Ships in 10 - 15 working days

Amyloid-forming proteins are implicated in over 30 human diseases. The proteins involved in each disease have unrelated sequences and dissimilar native structures, but they all undergo conformational alterations to form fibrillar polymers. The fibrillar assemblies accumulate progressively into disease-specific lesions in vivo. Substantial evidence suggests these lesions are the end state of aberrant protein folding whereas the actual disease-causing culprits likely are soluble, non-fibrillar assemblies preceding the aggregates. The non-fibrillar protein assemblies range from small, low-order oligomers to spherical, annular, and protofibrillar species. Oligomeric species are believed to mediate various pathogenic mechanisms that lead to cellular dysfunction, cytotoxicity, and cell loss, eventuating in disease-specific degeneration and systemic morbidity. The particular pathologies thus are determined by the afflicted cell types, organs, systems, and the proteins involved. Evidence suggests that the oligomeric species may share structural features and possibly common mechanisms of action. In many cases, the structure function interrelationships amongst the various protein assemblies described in vitro are still elusive. Deciphering these intricate structure function correlations will help understanding a complex array of pathogenic mechanisms, some of which may be common across different diseases albeit affecting different cell types and systems."

Alessandro Fatatis
R4,602 Discovery Miles 46 020 Ships in 10 - 15 working days

This work presents the most advanced discoveries from translational research laboratories directly involved in identifying molecules and signalling pathways that play an instrumental role in metastasis. In contrast to other works, conventionally focused on a single type of tumour, the various chapters in this book provide a broad perspective of the similarities and discrepancies among the dissemination of several solid malignancies. Through recurrent and overlapping references to molecular mechanisms and mediators, the readers will gain knowledge of the common ground in metastasis from a single source. Finally, an introductory chapter provides a clinical perspective of the problems presented by metastatic tumours for diagnosis and treatment. The work presented here is directed to researchers in tumour biology with a developing interest in metastatic dissemination as well as medical and graduate students seeking to expand and integrate the notions acquired in basic cancer biology and oncology courses.

It can be concluded (under the specific experimental procedures em ployed) that: - 1) HCG labelled with 1 - 2 atoms of radioactive iodine did not differ sig nificantly from the unlabelled hormone; 2) The ovary alone exhibited a capacity to affix specifically HCG; 3) The amount of radioactive material in the ovary was directly proport ional to the quantity of labelled HCG injected; 4) When the HCG present in the circulation is bound to an antiserum to HCG, the antigen-antibody complex is not concentrated by the ovary; 5) Circulating labelled HCG decreased to 50% within 30 minutes following a single intravenous injection; 6) There are four different phases of ovarian uptake of HCG, namely: the first phase, when there is only an inflow from the circulation and stor age mainly in the follicular envelopes; the second phase, when there is a greater inflow than outflow; the third phase, when the inflow is equal to the outflow; and the fourth period, when the outflow is bigger than the in flow.

Lactoferrin and its Role in Wound Healing (Paperback, 2012 ed.): Yoshiharu Takayama Lactoferrin and its Role in Wound Healing (Paperback, 2012 ed.)
Yoshiharu Takayama
R2,967 Discovery Miles 29 670 Ships in 10 - 15 working days

Lactoferrin is an iron-binding glycoprotein belonging to the transferrin family. It acts as a defense in host animals against microbes and viruses, since it has a broad spectrum of antimicrobial and antiviral activities. Lactoferrin has been shown to regulate the growth and differentiation of many types of cells. The results of recent studies indicate that lactoferrin is a potent regulator of dermal fibroblasts, and promotes cutaneous wound healing. The collagen gel contraction, a model of wound contraction during wound healing process, and migration of human fibroblasts were enhanced by lactoferrin. LRP-1 (LDL Receptor related Protein-1) acts as a signaling receptor for lactoferrin that mediate fibroblast response to lactoferrin by activating ERK/MAPK signaling pathway. In addition, lactoferrin promotes biosynthesis of extracellular matrix (ECM) component such as type-I collagen and hyaluronan. Hyaluronan is a major component of ECM in connective tissue and promotes wound healing. The promoting effect of lactoferrin on hyaluronan production was accompanied by promotion of HAS2 (hyaluronan synthase 2) expression. These observations suggest that lactoferrin promotes the wound healing by providing an ECM that promotes fibroblast migration. Lactoferrin is also known for its anti-inflammatory and immune modulating properties. According to recent in vivo study, lactoferrin promotes wound repair by promoting the early inflammatory phase of wound healing. Based on this, recombinant human lactoferrin was subsequently tested clinically in a Phase II trial in patients with diabetic ulcers and was found to be effective. Lactoferrin should be further evaluated in patients with diabetic and other types of ulcers.

Protein Folding and Misfolding - Shining Light by Infrared Spectroscopy (Paperback, 2012 ed.): Heinz Fabian, Dieter Naumann Protein Folding and Misfolding - Shining Light by Infrared Spectroscopy (Paperback, 2012 ed.)
Heinz Fabian, Dieter Naumann
R3,010 Discovery Miles 30 100 Ships in 10 - 15 working days

Infrared spectroscopy is a new and innovative technology to study protein folding/misfolding events in the broad arsenal of techniques conventionally used in this field. The progress in understanding protein folding and misfolding is primarily due to the development of biophysical methods which permit to probe conformational changes with high kinetic and structural resolution. The most commonly used approaches rely on rapid mixing methods to initiate the folding event via a sudden change in solvent conditions. Traditionally, techniques such as fluorescence, circular dichroism or visible absorption are applied to probe the process. In contrast to these techniques, infrared spectroscopy came into play only very recently, and the progress made in this field up to date which now permits to probe folding events over the time scale from picoseconds to minutes has not yet been discussed in a book. The aim of this book is to provide an overview of the developments as seen by some of the main contributors to the field. The chapters are not intended to give exhaustive reviews of the literature but, instead to illustrate examples demonstrating the sort of information, which infrared techniques can provide and how this information can be extracted from the experimental data. By discussing the strengths and limitations of the infrared approaches for the investigation of folding and misfolding mechanisms this book helps the reader to evaluate whether a particular system is appropriate for studies by infrared spectroscopy and which specific advantages the techniques offer to solve specific problems.

R2,972 Discovery Miles 29 720 Ships in 10 - 15 working days

There are nearly 100 000 different protein sequences encoded in the human genome, each with its own specific fold. Understanding how a newly formed polypeptide sequence finds its way to the correct fold is one of the greatest challenges in the modern structural biology. The aim of this thesis is to provide novel insights into protein folding by considering the problem from the point of view of statistical mechanics. The thesis starts by investigating the fundamental degrees of freedom in polypeptides that are responsible for the conformational transitions. This knowledge is then applied in the statistical mechanics description of helix coil transitions in polypeptides. Finally, the theoretical formalism is generalized to the case of proteins in an aqueous environment. The major novelty of this work lies in combining (a) a formalism based on fundamental physical properties of the system and (b) the resulting possibility of describing the folding unfolding transitions quantitatively. The clear physical nature of the formalism opens the way to further applications in a large variety of systems and processes.

The Symposium on "Protein Metabolism: Infiuence of Growth Hormone, Anabolie Steroids, and Nutrition in Health and Disease" is the fourth in the series of International Symposia sponsored by CIBA Limited, Basle. As in the case of the previous conferences, it was planned and organised with the help of experts in the field concerned. Special thanks are due to Prof. A. QuERIDO and Dr. A. A. H. KAssENAAR who, once the idea of the Symposium had been conceived in the course of joint discussions, embarked upon the project with enthusiasm and inspiration, although they must have known full weil what a great deal of time and trouble the organisation of such a meeting would inevitably cost them. For their untiring efforts, for the judicious manner in which they contrived to select precisely those subjects on which interest is chiefiy centred today, and-last but not least-for their success in finding competent specialists to participate in the proceedings, we wish to assure them of our sincere gratitude. To all the members of the Department of Clinical Endocrinology and Diseases of Metabolism, at the University Hospital in Leyden, who helped in preparing the meeting, we would likewise extend a warm vote of thanks. The fact that the present volume, featuring the papers and discussions of the Symposium, has been published only a few months after the event, was made possible thanks to the co operative help of all who participated.

The preceding volumes of Cell and Muscle Motility have focused on various aspects of motile systems in both muscle and non muscle cells. These essays have been critical reviews on topics of current interest and, hopefully, have provided a base from which future investigations may develop. During the past decade, however, much attention in the fields of biochemistry and cell biology has focused on motile systems in non muscle cells. Our current under- standing of the three-dimensional organization of the cytoplasm involve three major fibrous proteins which are collectively known as the cytoskeletal system. These polymorphic cytoskeletal proteins are microtubules (25-nm diameter), microfilaments (6-nm diameter), and intermediate filaments (lO-nm diame- ter). Microtubules consist of tubulin and several well-characterized micro- tubule associated proteins (MAPs) including MAP , MAP , tau, and others. l 2 Microfilaments consist of actin and associate with actin-binding proteins in- cluding a-actinin, filamin, myosin, tropomyosin, vinculin, and others. Inter- mediate filaments (lO-nm filaments) consist of at least five different tissue- specific classes, including desmin or skeletin (muscle), prekeratin (epithelial), vimentin (mesenchymal), neurofilament (nerve), and glial acidic fibrillary protein (astrocytes). These major fibrous proteins apparently interact with each other as well as other cytoplasmic components and appear to be inti- mately associated with such biological processes as cell shape changes, growth, motility, secretion, cell division, and uptake of materials from the exterior of the cell.

The Fifth Chinese Peptide Symposium, hosted by Lanzhou University, was held at Lanzhou, China July 14-17, 1998, with 156 participants, including 30 scientists from abroad, representing nine countries. The four-day conference was both intense and spiritually rewarding. Our goal for CPS-98 was to provide a forum for the exchange of knowledge, cooperation and friendship between the international and Chinese scientific communities, and we believe this goal was met. The symposium consisted of 8 sessions with 42 oral and 90 poster presentations, including synthetic methods, molecular diversity and peptide libraries, structure and conformation of peptides and proteins, bioactive peptides, peptide immunology, De Novo design and synthesis of proteins and peptides, ligand-receptor interactions, the chemistry-biology-interface and challenging problems in peptides. The enthusiastic cooperation and excellent contributions were gratifying and the active response of the invited speakers contributed to the success of the symposium. The presentations were of excellent caliber and represented the most current and significant aspects of peptide science. Dr. Kit Lam of the University of Arizona and Dr. Yun-Hua Ye of Peking University were the recipients of "The Cathay Award" sponsored by the H. H. Liu Education Foundation, offered for their seminal contribution in peptide science and the Chinese Peptide Symposium. Four outstanding young scientists were selected by the organizing committee to receive awards sponsored by Haikou Nanhai Pharmaceutical Industry Co. Ltd. (Zhong He Group).

R1,814 Discovery Miles 18 140 Ships in 10 - 15 working days

A key experiment in biomedical research is monitoring the expression of different proteins in order to detect changes that occur in biological systems under different experimental conditions. The method that is most widely used is the Western blot analysis. While Western blot is a workhorse in laboratories studying protein expression and has several advantages, it also has a number of significant limitations. In particular, the method is semi-quantitative with limited dynamic range. Western blot focuses on a single protein per sample with only a small number of representative samples analyzed in an experiment. New quantitative tools have been needed for some time to at least supplement, & possibly replace, the Western blot. Mass spectrometric methods have begun to compete with Western blot for routine quantitative analyses of proteins. One of these methods is based on the tandem mass spectrometry technique of selected reaction monitoring (SRM), which is also called multiple reaction monitoring (MRM). Selected reaction monitoring is actually an older tandem mass spectrometry technique, first described in the late 70s, that is widely utilized in the quantitative analysis of small molecules like drugs & metabolites. The use of selected reaction monitoring for the quantitative analysis of proteins has a number of advantages. Most importantly, it is fundamentally quantitative with a wide dynamic range. The output of the analysis is a numerical result that can range over several orders of magnitude. Other advantages include sufficient specificity & sensitivity to detect low abundance proteins in complex mixtures. Finally, selected reaction monitoring can be multiplexed to allow the quantitative analysis of relatively large numbers of proteins in a single sample in a single experiment. This Brief will explain both the theoretical & experimental details of the selected reaction monitoring experiment as it is applied to proteins.

This is a timely collection of important biomedical applications for a set of separation/characterization techniques that are rapidly gaining popularity due to their wide dynamic range, high resolution, and ability to function in most commonly used solvent systems. Importantly, the field-flow fractionation (FFF) technique has recently emerged as a prominent complement to size exclusion chromatography for protein pharmaceuticals. Fractionation with FFF is gentle and preserves protein structural integrity better than existing alternatives. In the present text, different chapters are written by experts in their respective field of application, who offer comparisons between the FFF techniques and other methods for characterizing their special focus material. Practical guide-lines for successful implementation, such as choice of operating conditions, are offered in conjunction with each application. In addition to new instrumentation and approaches that address important current topics, readers are provided with an overall sense of prior (but timeless) major developments that may be overlooked in literature searches.

Regulated turnover of extracellular matrix (ECM) is an important component of tissue homeostasis. In recent years, the enzymes that participate in, and control ECM turnover have been the focus of research that touches on development, tissue remodeling, inflammation and disease. This volume in the "Biology of Extracellular Matrix" series provides a review of the known classes of proteases that degrade ECM both outside and inside the cell. The specific EMC proteases that are discussed include cathepsins, bacterial collagenases, matrix metalloproteinases, meprins, serine proteases, and elastases. The volume also discusses the domains responsible for specific biochemical characteristics of the proteases and the physical interactions that occur when the protease interacts with substrate. The topics covered in this volume provide an important context for understanding the role that matrix-degrading proteases play in normal tissue remodeling and in diseases such as cancer and lung disease.

The essential question that fractal dimensions attempt to answer is about the scales in Nature. For a system as non-idealistic and complex as a protein, studying scale-invariance becomes particularly important.

"Fractal Symmetry of Protein Interior" investigates the diverse facets of the various scales at which we describe protein biophysical and biochemical phenomena. Following a thorough introduction to fractal dimensions, fractal-dimension-based approaches, that have been employed to study protein interior biophysical properties, are described. The focus is on the question which scales are scale-invariant? Investigations related to scaling of biophysical and biochemical behaviors may one day help us to formulate a fundamental theory about protein biophysics; which, in turn, may help us to understand fundamental principles of proteins."

R1,941 Discovery Miles 19 410 Ships in 10 - 15 working days

This Brief provides a concise review of chaperonopathies, i.e., diseases in which molecular chaperones play an etiologic-pathogenic role. Introductory chapters deal with the chaperoning system and chaperoning teams and networks, HSP-chaperone subpopulations, the locations and functions of chaperones, and chaperone genes in humans. Other chapters present the chaperonopathies in general, including their molecular features and mechanistic classification into by defect, excess, or mistake. Subsequent chapters discuss the chaperonopathies in more detail, focusing on their distinctive characteristics: primary or secondary; quantitative and/or qualitative; structural and hereditary or acquired; genetic polymorphisms; gene dysregulation; age-related; associated with cancer, chronic inflammatory conditions, and autoimmune diseases. The interconnections between the chaperoning and the immune systems in cancer development, chronic inflammation, autoimmunity, and ageing are outlined, which leads to a discussion on the future prospects of chaperonotherapy. The latter may consist of chaperone gene and protein replacement/supplementation in cases of deficiency and of gene or protein blocking when the chaperone actively promotes disease. The last chapter presents the extracellular chaperones and details on how the chaperone Hsp60 is secreted into the extracellular space and, thus, appears in the blood of cancer patients with potential to participate in carcinogenesis and chronic inflammation and autoimmunity. Chaperones as clinically useful biomarkers are mentioned when pertinent. Likewise, guidelines for clinical evaluation of chaperonopathies and for their histopathological and molecular identification are provided throughout. The book also provides extensive bibliography organized by chapter and topic with comments. "
