Immunocytochemistry for Steroid Receptors


Book Description

A comprehensive review of the literature on steroid hormone receptor immuncytochemistry. It includes the development of the first monoclonal antireceptor antibody and initial procedures designed to localize steroid receptors in situ up to the present. The step-by-step instructions provide easy reading of topics such as tissue handling, processing, and interpretation. This text places particular emphasis on the studies of human material-especially mammary carcinoma. It presents specific details with chapters on estrogen and progesterone receptors in breast malignancies and benign breast disease. Each section of this outstanding book contains comprehensive photomicrographs that illustrate the most salient features discussed. Detailed graphs pertaining to theoretical particulars concerning technology and the relationship between image analysis and endocrine response are also included. This monograph is an excellent resource for all researchers concerned with hormone-dependent tissues, pathologists who have an interest in working with novel techniques for localizing steroid hormone receptors, and oncologists who must use assay results in the treatment of breast cancer.







The Steroid/Thyroid Hormone Receptor Family and Gene Regulation


Book Description

The Second International CBT (Center for Biotechnology) Synposium was held in Stockholm November 4-5 1988 and had the title "The steroid/thyroid hoITIDne receptor family and gene regulation". This meeting contained contributions from most leading laboratories within the field of steroid/thyroid hOITIDne receptors and gave a very exciting perspective on the dynamic development of this i:ntx>rt. ant research field. Today all known steroid hoITIDne receptors have been cloned and sequenced and novel members of this supergene family are constantly being discovered. Sane of these new receptors remain to be characterized regarding the nature of their ligand. Access to probes for steroid receptors has enabled studies on mechanisms of regulation of receptor gene expression. Deletion and II'Altational analysis of steroid receptor cDNAs followed by expression in cells together with suitable reporter genes has yielded a detailed knowledge about the functional significance of the various domains the receptors are composed of. In certain cases, steroid resistance in patients have been shown to be due to point mutations in the corresponding steroid receptor genes resulting in non-functional receptors. The availability of receptor cDNAs also makes it possible to express receptors at high levels in procaryotic and eucaryotic cells. It is e. g. possible to express the DNA-binding domain of the glucocorticoid receptor in E. coli as a fusion protein with protein A which interacts specifically with DNA. Such studies are necessary for production of sufficient quantities of receptors to allow crystallization and X-ray crystallography for detailed structural information.

Steroid Receptors in Health and Disease


Book Description

During the last two decades, progress in steroid hormone research has resulted in the development of new approaches to contraception as well as diagnosis and treatment of endocrine disorders and cancers. Although significant advances have been made in the purification, characterization, immunochemistry and molecular biology of steroid receptors, the precise molecular mechanism of steroid hormone action has remained obscure. This book captures the detailed presentations made at the first conference on Steroid Receptors in Health and Disease held at Meadow Brook Hall, Oakland University in the fall of 1987. The purpose of this international con ference was to facilitate scientific exchange toward a better understand ing of the mode of action of steroid hormones. The scientific sessions consisted of poster presentations and state-of-the-art lectures, the latter of which make up this volume. The first chapter is meant to provide the reader with a more general background of the topics covered in the book, as well as to discuss certain theme-related issues that are either not yet well-established or accepted or are in the stage of infancy. It is hoped that this volume will serve as a useful treatise for students and investigators interested in basic and clinical aspects of biological regulation by steroid hormones. A task of this magnitude could not have been undertaken without the encouragement, advice and continued generous assistance of the members of the scientific committee. I am gratefully indebted to Drs.

Receptors


Book Description

Methods in Neurosciences, Volume 11: Receptors: Model Systems and Specific Receptors is a compilation of papers that describes techniques and information that are important to the neurosciences. This volume discusses preferred receptor techniques, molecular techniques, and methods to determine receptor subclasses and localization in the ligand design. The first paper discusses the steroid receptor found in the central nervous system for steroid hormones that affects strongly the structure and function of both developed and immature nervous systems. Another paper describes how a glycoprotein of 79.5 kDa (transferrin) carries iron in the blood stream for delivery to different tissues, after the transferrin has bound with a specific receptor on the surface of the cell. This book also explains the binding sites of pituitary adenylate cyclase-activating polypeptide in the human brain, while one paper analyzes the neurotensin receptors during the primary culture of neurons. This volume then also analyzes the structure and function of the fast nerve growth factor receptor, particularly how a signal on the outside of a cell is transmitted to the cell's interior. This collection is helpful for microbiologists, cellular researchers, students, and professors in the discipline of neurosciences.




Hormonally Active Agents in the Environment


Book Description

Some investigators have hypothesized that estrogens and other hormonally active agents found in the environment might be involved in breast cancer increases and sperm count declines in humans as well as deformities and reproductive problems seen in wildlife. This book looks in detail at the science behind the ominous prospect of "estrogen mimics" threatening health and well-being, from the level of ecosystems and populations to individual people and animals. The committee identifies research needs and offers specific recommendations to decision-makers. This authoritative volume: Critically evaluates the literature on hormonally active agents in the environment and identifies known and suspected toxicologic mechanisms and effects of fish, wildlife, and humans. Examines whether and how exposure to hormonally active agents occursâ€"in diet, in pharmaceuticals, from industrial releases into the environmentâ€"and why the debate centers on estrogens. Identifies significant uncertainties, limitations of knowledge, and weaknesses in the scientific literature. The book presents a wealth of information and investigates a wide range of examples across the spectrum of life that might be related to these agents.




Visualization of Receptors


Book Description

A multiplicity of methods for visualization are described in Visualization of Receptors. This book of techniques covers immunocytology, radioautography, in situ hybridization, plasmon resonance, RT in vitro PCR, and X-ray crystal structure analysis. Lecturers, researchers, practitioners, technicians, and students will find all the principles and protocols they require and the means of implementing them. Topics discussed include localization of ligands (in vitro or in vivo), visualization of immunoreactivities of ligand and receptor proteins, detection and quantification of mRNA expression, amplification of signals, and determination of 3-D structure. Details of protocols with illustrations of results and commentaries are provided throughout the book.




Monoclonal Antibodies in Diagnostic Immunohistochemistry
