Research into steroid receptor biology holds great promise for the treatment of cancer and endocrine disorders and for elucidating the fundamental biological mechanisms of gene expression. In Steroid Receptor Methods: Protocols and Assays, a distinguished team of principal investigators and their associates describe in step-by-step detail a cross-section of the latest research techniques available for studying the endocrine system. As a basis for sophisticated biochemical analysis of receptor properties, the contributors provide methods for the production and purification of a variety of receptors, including progesterone, glucocorticoid, and androgen. Other protocols allow the reader to experiment with DNA-binding characteristics and hormone-binding assays and with the use of combinatorial chemistry for drug discovery. A series of novel methods utilizing the latest advances in immunochemistry, yeast two-hybrid screening, and fluorescence are included for the detection and analysis of a variety of cellular proteins that influence steroid receptor effectiveness. Finally, a discussion by example presents the most current bioinformatics tools and analytical techniques. Timely and highly accessible, Steroid Receptor Methods: Protocols and Assays provides biochemists and molecular biologists studying endocrine systems with a full range of the powerful tools needed for elucidating protein interactions with receptors and DNA, as well as for drug discovery.

From the simple discovery in 1962 that resorbing tadpole tail expressed an enzyme (MMP) that could degrade collagen gels, matrix metalloproteinase (MMP) research has advanced to discover more than twenty distinct vertebrate MMPs and four specific inhibitors (TIMPS), a veritable family of enzymes involved in many physiological and pathological processes. In Matrix Metalloproteinase Protocols, leading experts detail proven laboratory techniques for the study of MMPs. The methods include those for the expression and purification of MMPs and TIMPs, for the detection of MMPs and TIMPs at both the protein and mRNA levels, and for the assay of MMP and TIMP activities in a wide variety of circumstances. Each method includes step-by-step instructions and notes on variant applications and pitfalls to avoid. A selective overview of the MMP arena spells out where the field has been, where it is, and where it is going. Comprehensive and highly practical, Matrix Metalloproteinase Protocols brings together the long and hard-earned experience of master experimentalists that will allow not only novices to get up to speed quickly, but also add to the repertoire of successful techniques in expert laboratories.

Proteoglycans, highly complex macromolecules found in mammalian and lower organisms, serve a multitude of biological functions. In Proteoglycan Protocols, Renato Iozzo, MD, and an authoritative team of investigators present for the first time a comprehensive and up-to-date collection of readily reproducible preparative and analytical methods for the in-depth analysis of these important compounds. Featuring step-by-step protocols, this book will enable both novice and experienced researchers to isolate intact proteoglycans from tissues and cultured cells, to establish the composition of their carbohydrate moieties, and to generate strategies for prokaryotic and eukaryotic expression. There are also detailed techniques for the suppression of specific proteoglycan genes, for the detection of mutant cells and their degradation products, and for studying specific interactions between proteoglycans and extracellular matrix proteins and with growth factors and their receptors. Each method is carefully described by leading experts in the field and includes practical considerations that are often lacking in formal papers. Authoritative and detailed, Proteoglycan Protocols offers molecular and cellular biologists, biochemists, pathologists, and geneticists a comprehensive reference and practical guide to the most common methods used today for the isolation and characterization of proteoglycans from cultured cells, tissues, and biological fluids.

Alkaloids: Chemical and Biological Perspectives, the 15th volume of the ACBP series, features four important reviews of research on alkaloids. Chapter 1 is the first comprehensive review of the carbon-13 and proton NMR shift assignments and physical constants of diterpene alkaloids and their derivatives. In addition to the catalogue of spectral and physical data, the chapter includes a table of the occurrences of these alkaloids in various plant species, tables containing molecular formulas versus calculated high-resolution mass values, and calculated high-resolution mass values versu

Theoretical chemistry has been an area of tremendous expansion and development over the past decade; from an approach where we were able to treat only a few atoms quantum mechanically or make fairly crude molecular dynamics simulations, into a discipline with an accuracy and predictive power that has rendered it an essential complementary tool to experiment in basically all areas of science. This volume gives a flavour of the types of problems in biochemistry that theoretical calculations can solve at present, and illustrates the tremendous predictive power these approaches possess.
