Description

Advances in the Biosciences 7: Schering Workshop on Steroid Hormone ""Receptors,"" Berlin, December 7 to 9, 1970 is a collection of papers presented at the Schering Workshop on Steroid Hormone ""Receptors,"" held in Berlin, Germany, on December 7-9, 1970. Contributors review research findings concerning steroid hormone receptors and cover topics organized around receptors of estrogen, androgen, progesterone, aldosterone, and corticosteroids.

This book is comprised of 20 chapters and begins by analyzing the concentration of the estrogen binding protein in the rat uterus in three stages of uterine development, followed by a discussion on estradiol binding in mammalian tissues. The next section explores androgen receptors and includes chapters dealing with the specific binding of steroid-receptor complexes to DNA as well as the effects of androgen receptors on rat and human prostate. Subsequent chapters discuss the action of progesterone, aldosterone, and corticosteroid receptors.

This monograph will be of interest to biochemists, biologists, and physiologists.
