摘要
Mitochondria, once viewed as functioning relatively autonomously in the cell, have increasingly been recognized to be involved in numerous signaling networks that impact on a wide range of cell biological processes. In addition to the many types of proteins that mediate these pathways, the importance of signaling functions regulated via lipids and lipid second messengers generated on the mitochondrial surface is also becoming well appreciated. We focus here on phosphatidic acid, a lipid second messenger produced via several different pathways that can in turn stimulate the formation of multiple other bioactive lipids. Taken together, fascinating roles for phosphatidic acid and the connected lipids in mitochondrial function and interaction with other organelles are being uncovered. These pathways present new opportunities for the development of therapeutic approaches relevant to reproduction, metabolism, and neurodegenerative disease. (C) 2012 Elsevier Ltd. All rights reserved.
