Available in PDF, EPUB and Kindle. Book excerpt: Hormonal Steroids: Biochemistry, Pharmacology, and Therapeutics, Volume I focuses on various research on steroids and their biological and medical involvements. Comprised of 60 chapters, the book presents the literature of various authors who have conducted research on the relationship between hormonal steroids and biochemistry, pharmacology, and therapeutics. The discussions start with the identification of steroids with hormone-like activities. This discussion includes the nature, compositions, properties, possible uses, and reactions of these hormones when exposed to different conditions and controlled environments. The book then proceeds with discussions on synthesis and metabolism of hormonal steroids. These discussions are supported by graphical representations, reviews, recommendations, and methodologies. The book then explains the control of synthesis and release of steroid hormones. This part notes the relationship of renal and adrenal hormones; the control and production of corticosterone; neurosecretion and control of the pituitary gland; and release of ovulating hormones. The book also highlights the mechanism of steroid action, noting the probable interrelationships of steroids, nonsteroids, intermediary metabolism, and inflammation. Various research are presented on the possible clinical applications of steroids. The text is a vital reference for readers who are interested in the study of hormones.
Download or read book Gene Regulation by Steroid Hormones written by A.K. Roy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last two decades endocrinological research has taken a definite tum toward biochemistry and molecular biology. This has resulted in a new discipline called' 'molecular endocrinology. " Studies on the mechanism of hormone action have continued to make headlines with fundamental discov eries in receptor action and gene regulation. Recently the insect endocrino logists have also begun to explore the molecular mechanism of steroid hor mone action taking advantage of the vast number of Drosophila mutants, the library of Drosophila gene, and several well-characterized cell-lines. The availability ofthe recombinant DNA technology has provided a truly revolu tionary tool in the hands of the molecular endocrinologists. "Gene Regula tion by Steroid Hormones" is compiled and presented in this frontier spirit, and we hope that this volume will serve not only the active investigators in the field but will also be very useful to students and researchers with a gen eral interest in regulatory biology. The book is an offshoot of the Conference on Molecular Mechanism of Steroid Hormone Action held at the Meadow Brook Mansion of Oakland University in the fall of 1978. We wish to acknowledge the financial assist ance from the National Science Foundation and Oakland University. The conferees will never forget the warmest hospitality of Dr. LOWELL EKLUND and his staff at the Meadow Brook center and we also wish to express per sonal gratitude to many of our students and colleagues for helping us to make the conference a great success.

Download or read book Steroid and Sterol Hormone Action written by Thomas C. Spelsberg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to focus attention on recent developments in steroid and sterol hormone action. Many authors have generously contributed to the book. As a result, there is a great diversity of opinion! A majority of the chapters deal with steroid or sterol hormone receptors. This is not meant to imply that receptor-mediated mechanisms are the sole or even the most important mechanisms by which steroid hormones act in the cell. There is wealth of evidence showing that other, non-receptor events, are important also. Steroid hormone recep tor research and the study of nuclear events mediated by steroids are presently the most intensely studied aspects of sterol hormone action and our selection of topics reflects this trend. We have also included chapters on vitamin 0 sterols and thyroid hormone in the book, as there is pood evidence that these hormones act in a manner similar to other classical steroids. 1 IMMUNOCHARACTERIZATION OF THE NUCLEAR ACCEPTOR SITES FOR THE AVIAN OVIDUCT PROGESTERONE RECEPTOR A. GOLDBERGER, M. HORTON, T. C. SPELSBERG Department of Biochemistry and Molecular Biology, Mayo Clinic and Mayo Graduate School of Medicine, Rochester, MN 55905 INTRODUCTION It is well known that steroid hormones, certain vitamins and sterols, enter target cells and bind to specific protein receptors in the cyto plasm or nucleus (1-4). This binding is saturable, high affinity, and steroid specific.

This book was released on 2012-12-06 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intracellular Receptors: New Instruments for a Symphony of Signals In the late eighteenth century, it was proposed on theoretical grounds that each of the body's organs, beginning with the brain, must be "a factory and laboratory of a specific humor which it returns to the blood", and that these circulating signals "are indispensable for the life of the whole" (Bordeu 1775). During the nineteenth cen tury, some remarkable physiological experiments revealed the actions of humoral factors that affected the for and function of multiple tissues, organs and organ sys tems within the body (Berthold 1849); much later, the chemical and molecular na ture of some of those factors was determined. Against this deep historical backdrop of the founding studies of intercellular signaling, molecular biology sprang into existence a mere forty years ago, rooted in the revelation of regulable gene expression in bacteria. But contemporaneous with those classical analyses of transcriptional regulation of the lactose operon, the mod em era of signal transduction was inaugurated by the identification of cAMP as a second messenger -- an intracellular mediator of hormonal activation of glycogen catabolism (Sutherland and RaIl 1960). Later in that same decade, it emerged that cAMP is a critical signal not only in metazoans, but even in bacteria, where it serves an analogous function as a critical switch that activates expression of genes re quired for catabolism of complex carbon sources, including those of the lactose operon.

Download or read book Steroid Cell Interactions written by R. J. B. King and published by Elsevier. This book was released on 2014-05-20 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steroid–Cell Interactions describes the processes involved in the intracellular binding of steroids (and related compounds) in mammalian cells. Serum binding proteins and steroid-immunoglobulin interaction are also discussed, along with the relationship of these binding processes to the biological action of the steroid. This book consists of 10 chapters and begins by presenting an elementary account of the factors contributing to the interaction between a steroid hormone and another molecule. The discussion then turns to the three types of methods used to study the interaction between steroids and tissue receptors: cell fractionation, autoradiography, and the separation of specifically and non-specifically bound steroids. The next chapter deals with the metabolism of steroid hormones in relation to their binding and mechanism of action, focusing on testosterone and progesterone. The reader is also introduced to the intracellular binding of androgens, glucocorticoids, mineralocorticoids, and estrogens and to how binding is related to biological activity. The final chapter reviews the clinical and immunological data relevant to steroid-protein binding. This text will be of interest to students and practitioners of biology, biochemistry, and physiology.
Download or read book Steroids and Neuronal Activity written by Derek J. Chadwick and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical studies of steroid hormones are concerned with their regulation of protein synthesis via the modulation of genomic transcription. But many of the actions of these hormones occur too rapidly to be explained in this manner, particularly their effects on the central nervous system. This text deals with recent discoveries showing that steroids can modulate the activity of some neurotransmitters. It explores the role of GABA as an important regulator of neuronal activity in the central nervous system and its inhibitory action as mediated via the GABA receptor and potentiated by steroids. In addition, the binding of steroids to cell membranes, the components involved and the outcome of such interactions are described. Also discusses possible uses of steroids as anesthetics and anticonvulsants.
