Steroid Hormone Action is a comprehensive overview of the molecular mechanisms by which these hormones regulate the expression of specific target genes. The book covers the structure of steroid receptors, transcriptional activation and repression, and also contains chapters on steroid bindingproteins and steroidogenesis. Steroid receptors represent one of the best characterized transcription factors so that the book will be of general interest to Molecular Biologists studying eucaryotic gene regulation. Chapters on the mechanisms of action of steoid antagonists and defective receptorsin target cells will be of particular interest to Endocrinologists and Clinicians. In such a rapidly progressing field it is difficult to keep up with all the literature but this book, written by international experts, focuses on the most important advances that have been made recently.
