This book provides descriptions of experimental methods in research on the cytoskeleton and its relationships to signaling and cell regulation. Thus, it bridges two active and fertile areas of research. The focus is directed particularly towards methods which take advantage of recent advances in molecular biology, microscopy and immunological assays. A second emphasis is on methods for understanding dynamic changes in cells. A third emphasis is on the formation and turnover of macromolecular and supramolecular complexes, which are so important in driving cell regulation and the behaviour of cytoskeletal elements. A combination of practical advice and detailed protocols should make this book valuable for both novice and experienced workers in these burgeoning fields.

This monograph explores the relationships between cell signaling and the cytoplasmic cytoskeleton in fundamental cell processes, thus bridging the gap between two very active aspects of molecular cell biology. It covers the two main - and reciprocal - questions of these relationships: How are structure and function of the cytoskeleton affected by external signals which impinge on the cell? How does the cytoskeleton influence the cellular signaling processes which determine cell behavior?

The cytoskeleton is a highly dynamic intracellular platform constituted by a three-dimensional network of proteins responsible for key cellular roles as structure and shape, cell growth and development, and offering to the cell with "motility" that being the ability of the entire cell to move and for material to be moved within the cell in a regulated fashion (vesicle trafficking). The present edition of Cytoskeleton provides new insights into the structure-functional features, dynamics, and cytoskeleton's relationship to diseases. The authors' contribution in this book will be of substantial importance to a wide audience such as clinicians, researches, educators, and students interested in getting updated knowledge about molecular basis of cytoskeleton, such as regulation of cell vital processes by actin-binding proteins as cell morphogenesis, motility, their implications in cell signaling, as well as strategies for clinical trial and alternative therapies based in multitargeting molecules to tackle diseases, that is, cancer.

This book features contributions from experts in cell biology, genetics, neurobiology, immunology and structural biology. The unifying element is that they all study processes of cell shape change and motility. Several key questions in this field of research are discussed: What are the organising principles behind cell shape change? Are there ‘master switches’ present in every cell type? How are extracellular signals interpreted by the cell in order to activate intracellular mechanisms? What is the influence of the extracellular matrix on cell movement and internal signalling pathways? How do pathogens subvert cellular systems in order to stimulate or block their uptake? The book addresses all of these important questions. Data are presented on the key proteins that regulate cell shape: the GTP binding proteins of the Rho family. There are also extensive discussions of the potential applications of the data to clinical problems, particularly that of cell motility in cancer.

This volume provides an overview of the cytoskeleton particularly on the fundamental role the cytoskeleton plays in the regulation of cell structure and function. This book represents new trends in cytoskeletal research that go beyond the traditional approach of identifying new proteins in the cytoskeleton, but actually define how these proteins interact with signaling pathways. While the major emphasis in this volume remains on the microfilament structure, some discussion has been included in this volume to illustrate the similarities and differences between the three cytoskeletal elements namely the actin microfilament, the intermediate filaments and the microtubules.
