项目摘要
PROJECT SUMMARY
A plethora of receptor-mediated signaling pathways initiate production of the lipid messenger phosphatidic acid
(PtdOH). Direct activation of phospholipase D (PLD) leads to distinctive molecular species of PtdOH that bind
to a variety of cellular targets. A less direct pathway is the receptor-mediated process of phospholipase C
(PLC) generation of diacylglycerol with subsequent lipid phosphorylation via diacylglycerol kinase (DGK)
leading to downstream production of PtdOH. A third pathway includes direct de novo generation of PtdOH via
the Kennedy Pathway. Surprisingly, these pathways from cell surface receptors and constitutively activated
pathways leading to PtdOH production are largely uncharacterized. While some of the signaling components
such as Arf GTPases, Rho GTPases, protein kinase C, among others have been identified, a well detailed map
elucidating the network has not as yet been charted. In this project we use a multi-omics approach to identify
key components of these phosphatidic acid signaling pathways looking at the downstream effectors,
consequences to membrane lipid composition, intracellular metabolic pathways, innate immune components
and other targets of phosphatidic acid signaling. This will provide a basis for understanding how phosphatidic
acid signaling contributes to a number of important human pathologies that includes cancer, infectious
diseases, and neurodegenerative disorders.
