Book Description
Adhesion molecules are of fundamental importance in the regulation of immunity, inflammation, tissue remodeling, and embryonic development. They comprise different families of homologous proteins, such as selectins, integrins, cadherins, and immunoglobins. In addition, beyond these groups, other str- tures with adhesive properties, such as proteoglycans, occludin, and CD44, have been characterized recently. An understanding of the type and characteristics of adhesive molecules expressed by the different cell types and the possibility of manipulating their activity promises considerable clinical potential. Antibodies, small peptidic and nonpeptidic molecules, have recently been used to inhibit thrombosis by blocking platelet aggregation or inflammation through inhibition of leukocyte infiltration and adhesion. Inhibitors of adhesive molecules are used in expe- mental systems for the study of tumor growth and dissemination. Among major goals in the field are the identification of new members of the known adhesive protein families and of independent new adhesive structures. After structural characterization, even more demanding is the study of the biological activity of the new proteins, and the development of simple, rapid tests for the screening of possible inhibitors. In this regard, the production of such reagents as fragments and antibodies would help define the structure–function relati- ship of individual proteins. Data available in the literature show the complexity of the adhesive process and how different molecular epitopes might contribute to the adhesive properties of a single structure. Finally, a new area of investi- tion is the characterization of the intracellular signaling cascade triggered by the engagement of transmembrane adhesive proteins.

Book Description
Integrins play pivotal roles not only across a wide range of physiological processes including tissue morphogenesis, immune responses, wound healing, and regulation of cell growth and differentiation, but also in numerous pathological phenomena such as autoimmunity, thrombosis, and cancer metastasis/progression. Therefore, investigations on integrins often demand multi-disciplinary approaches, making researchers long for a handy collection of comprehensive and practical protocols that detail experimental methods for studying integrin and related cell adhesion molecule functionality. Integrin and Cell Adhesion Molecules: Methods and Protocols aims to provide readers not only with basic protocols in studying integrin functions, but also with summaries on those state-of-the-art technologies that have been utilized for understanding integrin functionality at the cellular, molecular, structural, and organismal levels. Divided into six convenient sections, this detailed volume covers basic protocols for the study of integrin and related cell adhesion molecule functionality in vitro, illustrates structural biology approaches for studying integrins and related cell adhesion molecules, focuses on emerging imaging technologies for investigating cell migration, presents strategies to elucidate signaling through cell adhesion molecules, includes experimental techniques to investigate integrin functions at organismal levels in a physiological context, and showcases the most promising methods and technologies for the development of novel therapeutics and diagnostics. Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Both experts and non-experts in the scientific community who wish to study cell adhesion molecules and diagnostics will find Integrin and Cell Adhesion Molecules: Methods and Protocols authoritative, easily accessible, and vastly informative.

Book Description
It is now widely accepted that much of the dynamic function of cells and tissues is regulated from outside the cell by the extracellular matrix. In ad- tion to its conventional role in providing a scaffold for building tissues, the extracellular matrix acts as a directional highway for cellular movement and provides instructional information for promoting survival, proliferation, and differentiation. Indeed, the extracellular matrix is beginning to take a starring role in the choreography of cell and tissue function. The diverse roles of the extracellular matrix are reflected in its highly complicated structure, consisting of an ever increasing number of components. Yet the mechanisms of extracellular matrix assembly and how they influences cell behavior are only just beginning to be understood. In order to solve these problems new methodologies are, of necessity, being developed. Many of these technologies are highly sophisticated and are currently available only in a ha- ful of laboratories. However, we believe that they can readily be transported and established by other researchers. Thus, the purpose of Extracellular Matrix Protocols is to present some of these complicated techniques in a style that is relatively easy to reproduce.

Book Description
The Protein Protocols Handbook, Second Edition aims to provide a cross-section of analytical techniques commonly used for proteins and peptides, thus providing a benchtop manual and guide for those who are new to the protein chemistry laboratory and for those more established workers who wish to use a technique for the first time. All chapters are written in the same format as that used in the Methods in Molecular BiologyTM series. Each chapter opens with a description of the basic theory behind the method being described. The Materials section lists all the chemicals, reagents, buffers, and other materials necessary for carrying out the protocol. Since the principal goal of the book is to provide experimentalists with a full account of the practical steps necessary for carrying out each protocol successfully, the Methods section contains detailed st- by-step descriptions of every protocol that should result in the successful execution of each method. The Notes section complements the Methods material by indicating how best to deal with any problem or difficulty that may arise when using a given technique, and how to go about making the widest variety of modifications or alterations to the protocol. Since the first edition of this book was published in 1996 there have, of course, been significant developments in the field of protein chemistry.

Book Description
"Proteins are ubiquitous in biological systems and while much is known about protein structure, less is known about the movement of these proteins. The phenomenon of movement also occurs at the cellular level through cell migration and, in particular, cells depend upon the movement of proteins to enable cell motility. More precisely, cell migration is dependent upon cytoskeletal structures, including focal adhesions, complexes which include multiple proteins and enable cells to exert forces upon the underlying substrate and migrate. The basic structure and components of the cytoskeleton are fairly well known, yet much less is known about their dynamic assembly and disassembly. Motile cells are known to be involved in numerous biological processes and thus studying the flow of proteins involved in cell migration has the potential to clarify their roles and lead to a more advanced understanding of cell migration. Major protein components that play a role in the formation of focal adhesions have been identified. Using genetically engineered fluorescent variants of these proteins, we can image cells expressing fluorescently-tagged proteins via fluorescence microscopy, and thereby obtain quantitative results on the location and movement of key proteins of interest in migrating cells. In this work, a correlation analysis was performed on the measured fluorescence fluctuations within image series in order to determine the magnitude and direction of protein flows within sub-regions of migrating cells. The correlation analysis technique known as STICS (spatiotemporal image correlation spectroscopy) was utilized and accomplishes this by using the full spatiotemporal correlation function. It is important that fluorescence variations in space throughout the cell as well as variations through time be investigated in the image series. STICS is well suited for this as it provides vector map image series of the fluorescent protein flows. A principal aspect of this thesis is performing the STICS correlation analysis on image series of cells containing fluorescently-tagged versions of 5 key adhesion proteins with cells on substrates of different rigidities. Another principal aspect is to track and measure the development of adhesions simultaneously with the STICS analysis of protein flows that take part in focal adhesion development. In order to designate the STICS flows detected in the neighborhood of adhesions to specific adhesions correctly, image processing methods were employed including filtering of noise in space and in time, adhesion segmentation and adhesions tracking. Image series were treated for noise sources with image filtering in the spatial domain to remove background noise and in the temporal domain using a Butterworth filter to remove lower frequencies that obscure the signal of interest from adhesion protein populations exhibiting directed flow. For a large number of focal adhesions, local flows were obtained throughout trajectories using STICS correlation analysis of fluorescence fluctuations, while also measuring the physical properties of the focal adhesions. The adhesion analysis protocol developed for this thesis tracks all adhesions detected from the cell's expressed fluorescent proteins, and provides a neighbourhood STICS flow at each frame for tracked adhesions along their trajectories. As well, physical properties including adhesion area, major axis length, and adhesion speeds are obtained for each frame along the trajectories of tracked adhesions. Distributions of adhesion physical properties and local protein flow speeds were obtained for adhesions across multiple NIH3T3 cells for five adhesion proteins: paxillin, vinculin, talin, actin, and [alpha]-actinin. A substrate most resembling glass was first used, followed by a substrate with a greater concentration of the endogenous fibronectin to decrease substrate rigidity.
