This is the first book to exclusively address the actions of calcium-regulating hormones and peptides in the cardiovascular system. With 111 illustrations and 13 tables, this comprehensive volume includes: An extensive and critical review of present knowledge of the structure, synthesis, secretion, metabolism, receptors, signal transduction, and actions on classical target cells of each of the calcium-regulating hormones and peptides Discussions on parathyroid hormone and calcitonin, parathyroid hormone-related protein, parathyroid hypertensive factor, 1,25 dihydroxyvitamin D3, calcitonin gene-related peptide, and certain steroid hormones in terms of vascular biology and cardiac function The integrated physiology of calcium-regulating hormones in terms of blood pressure regulation in normotensive and hypertensive settings State-of-the-art electrophysiological techniques used by leading cardiovascular biologists to assess calciotropic hormone effects on calcium channel currents in both vascular smooth muscle and cardiac myocytes Studies on the regulation of hormone and receptor gene expression in the context of possible regulation of local and systemic blood flow and cardiac function by calcium-regulating hormones and peptides
