Integrin Protocols (Methods in Molecular Biology)

It is now widely accepted that the extracellular matrix (ECM) is a key determinant of tissue-specific gene expression. Signals provided by ECM are transduced by integrins, a large and growing superfamily of transmembrane heterodimeric cell surface receptors that link the ECM to structural and fu- tional elements within the cell. A wide range of cellular phenotypes have been shown to be regulated by integrins, including growth, differentiation, mig- tion, invasion, angiogenesis, and apoptosis. Furthermore, abnormalities of integrin expression and function have been implicated in the etiology of va- ous pathologic conditions, including cardiovascular disease, inflammatory disorders, and cancer. Thus integrins have emerged as an important class of molecules with wide ranging implications for understanding basic biological processes. In Integrin Protocols we provide a wide-ranging collection of laboratory protocols intended to assist investigators interested in integrins in working productively with these molecules, in studying their expression, and in pot- tially manipulating that expression to define their role(s) in relevant biolo- cal models. Protocols are provided for the analysis of integrin expression both at the RNA and protein levels (Chaps. 2, 5, and 7). Delcommenne and Streuli describe procedures for making rat monoclonal antibodies specific for mouse integrins; Schneller et al. and Arap and Huang describe methods for western blotting of integrins and RT-PCR analysis. Protocols are included that cover the analysis of the functional properties of integrins (Chaps. 1, 3, 4, 8, and 9 through 11). Koivunen et al.

In Integrin Protocols, Anthony Howlett and a distinguished panel of experimentalists describe in detail a series of cutting-edge methods for dissecting the role of integrins in biological processes. This wide-ranging collection includes protocols for the analysis of integrin expression-at both the RNA and protein levels-and for elucidating the functional properties of integrins, including those at the cellular level. Each method provides step-by-step instructions for easy reproducibility, along with extensive notes about potential pitfalls, and tips on how to avoid failure. The emphasis is always on the practical steps necessary for experimental success and robust results.
Offering powerful tools for understanding how integrins regulate cell growth, differentiation, migration, invasion, angiogenesis, and apoptosis, as well as how abnormalities of integrin expression and function may be implicated in various pathologic conditions, Integrin Protocols constitutes a gold-standard collection of techniques for both new and experienced investigators of the molecular and cellular basis of cardiovascular disease, inflammatory disorders, and cancer.
