Mechanisms Of Hormone Action

Mechanisms of Hormone Action: A NATO Advanced Study Institute focuses on the action mechanisms of hormones, including regulation of proteins, hormone actions, and biosynthesis. The selection first offers information on hormone action at the cell membrane and a new approach to the structure of polypeptides and proteins in biological systems, such as the membranes of cells. Discussions focus on the cell membrane as a possible locus for the hormone receptor; gaps in understanding of the molecular organization of the cell membrane; and a possible model of hormone action at the membrane level. The text also ponders on insulin and regulation of protein biosynthesis, including insulin and protein biosynthesis, insulin and nucleic acid metabolism, and proposal as to the mode of action of insulin in stimulating protein synthesis. The publication elaborates on the action of a neurohypophysial hormone in an elasmobranch fish; the effect of ecdysone on gene activity patterns in giant chromosomes; and action of ecdysone on RNA and protein metabolism in the blowfly, Calliphora erythrocephala. Topics include nature of the enzyme induction, ecdysone and RNA metabolism, and nature of the epidermis nuclear RNA fractions isolated by the Georgiev method. The selection is a valuable reference for readers interested in the mechanisms of hormone action.

Introduction to Mechanisms of Hormone Action considers the mechanisms of hormone action on cellular and genetic level. This book is composed of nine chapters that cover some basic aspects of cell structure and function. The opening chapter presents a brief introduction to the chemical nature and sources of local and general hormones, as well as the multicellular organization and control in cells. The succeeding chapters are devoted to the mechanisms of action of some hormones in the cell membrane, including acetylcholine, insulin, and adrenaline. Other chapters are concerned with the hormones acting at the genetic level, such as cortisone, sex steroids, and ecdysone. The final chapter discusses the action of growth hormones on ribosomal translation of mRNA. This book is of value to endocrinologists, cell biologists, and geneticists.

The purpose of the present volume is to focus on more recent aspects of the complex regulation of hormonal action, in particular in 3 different hot fields: metabolism, growth and reproduction. Modern approaches to the physiology and pathology of endocrine glands are based on cellular and molecular investigation of genes, peptide, hormones, protein cascade at different levels. In all of the chapters in the book all, or at least some, of these aspects are described in order to increase the endocrine knowledge.

This book presents the current aspects of the complex regulation of hormonal action. Novel approaches to the pathology and physiology of endocrine glands are established on molecular and cellular research of peptide, protein cascade, hormones, and genes at distinct levels. All these aspects are described extensively under the sections "Growth & Reproduction" and "Gynecological Endocrinology." The reader will benefit from the state-of-the-art endocrine knowledge provided in the book.

Recent years have seen tremendous progress in the field of hormone action and consequent signal transduction. The 40th Colloquium Mosbach was devoted to the discussion of results concerning the molecular process of hormone action, especially the processes following hormone binding to the corresponding receptors. Structural and functional aspects of steroid hormone receptors as well as ion-channel-coupled and enzyme-linked receptors were treated in detail. Particular interest focussed on the latest results concerning transcriptional control, protein phosphorylation, the role of G-Proteins, oncogene proteins, involvement of phospholipases and the regulation of ion channels.
