The discovery that inositol lipids are integral in cellular signaling mechanisms has been one of the most exciting breakthroughs in recent years. As secondary messengers in a wide variety of tissues and involved processes as diverse as rapid contraction of skeletal muscle, insulin secretion, and the slow activation of cell proliferation in cancer cells, their impact on biochemistry is akin to that of cyclic AMP two decades ago. Drawing together the many strands of research on inositol lipid-mediated signalling and containing contributions by leading authorities in their fields, Inositol Lipids in Cell Signalling is essential for any involved biochemist, cell biologist, or pharmacologist.
