Book Description
The concept of hormonal regulation using intercellular peptide messengers dates back to the discovery of secretin in 1902. The concept was simple: A peptide is released from specific hormone producing cells, endocrine cells, into circulation upon stimulation of the cells. The peptide hormone travels via blood to its target, the cells of which are equipped with specific receptors for high-affinity binding of the particular peptide hormone. Receptor binding subsequently elicits action of the target cells. This concept has been seriously challenged by modern biochemistry and cell biology. Thus, it is now well established that the gene of a specific peptide hormone may be expressed in different types of endocrine cells, in neurons, and in some instances also in adipocytes, myocytes, osteoblasts, and immune cells. Today, only a few hormones – including the old master hormone insulin – represent the original endocrine paradigm. Instead, the widespread cellular synthesis now raises the qu- tion of how the body maintains the regulation of its functions by peptide hormones when a hormone may originate from a variety of cells.

Book Description
Hormones provides a comprehensive treatment of human hormones viewed in the light of modern theories of hormone action and in the context of current understanding of subcellular and cellular architecture and classical organ physiology. The book begins with discussions of the first principles of hormone action and the seven classes of steroid hormones and their chemistry, biosynthesis, and metabolism. These are followed by separate chapters that address either a classical endocrine system, e.g., hypothalamic hormones, posterior pituitary hormones, anterior pituitary hormones, ,thyroid hormones, pancreatic hormones, gastrointestinal hormones, calcium regulating hormones, adrenal corticoids, hormones of the adrenal medulla, androgens, estrogens and progestins, and pregnancy and lactation hormones; or newer domains of hormone action which are essential to a comprehensive understanding of hormone action, including prostaglandins, thymus hormones, and pineal hormones. The book concludes with a presentation of hormones of the future, i.e., cell growth factors. This book is intended for use by first-year medical students, graduate students, and advanced undergraduates in the biological sciences. It is also hoped that this book will fill the void that exists for resource materials for teaching cellular and molecular endocrinology and that it will be employed as an equal partner with most standard biochemistry textbooks to provide a comprehensive and balanced coverage of this realm of biology.

Book Description
The prohormone convertases (PC) 1/3 and 2 are calcium-activated eukaryotic subtilisins with low pH optima which accomplish the limited proteolysis of peptide hormone precursors within neurons and endocrine cells. In this lecture, we review the biochemistry, regulation, and roles of PC1/3 and 2 in disease, with an emphasis on the work published in the last 10 years. In the 20 years since their discovery, a great deal has been learned about their localization and cellular functions. Both PCs share the same four domains: the propeptides perform important roles in controlling activation and targeting; the catalytic domains confer specificity, with PC1/3 possessing a more restricted binding pocket than that of PC2; the P domain is required for expression and contributes to enzymatic properties; and the C-terminal tail assists in proper routing to granules. PC1/3, but not PC2, exists in full-length and C-terminally truncated forms that exhibit different biochemical properties. Both enzymes associate with binding proteins; proSAAS is thought to modulate precursor cleavage by PC1/3, while co-expression of 7B2 is obligatory for the formation of active PC2. Finally, new studies have revealed an increasingly important role for PC1/3 polymorphisms and mutations in glucose homeostasis and obesity.

Book Description
This volume provides comprehensive coverage of the current knowledge of the physiology of the endocrine system and hormone synthesis and release, transport, and action at the molecular and cellular levels. It presents essential as well as in-depth information of value to both medical students and specialists in Endocrinology, Gynecology, Pediatrics, and Internal Medicine. Although it is well established that the endocrine system regulates essential functions involved in growth, reproduction, and homeostasis, it is increasingly being recognized that this complex regulatory system comprises not only hormones secreted by the classic endocrine glands but also hormones and regulatory factors produced by many organs, and involves extensive crosstalk with the neural and immune system. At the same time, our knowledge of the molecular basis of hormone action has greatly improved. Understanding this complexity of endocrine physiology is crucial to prevent endocrine disorders, to improve the sensitivity of our diagnostic tools, and to provide the rationale for pharmacological, immunological, or genetic interventions. It is such understanding that this book is designed to foster.
