A concise up-to-date treatise on the transduction signals that are induced by calcium. It also considers how alterations in this calcium-dependent signal transduction pathway are related to a number of human diseases, especially focusing on neoplastic transformation. This authoritative text examines the various signaling pathways along with associated mechanisms and examines a broad range of topics-from mechanisms and significance of calcium homeostasis for normal cell function to calcium signaling pathways and the transduction of the calcium signal especially in proliferation.
