Phosphatidylethanolamine positively regulates autophagy and longevity [PDF]

Cell Death & Differentiation, 2015
Autophagy is a cellular recycling program that retards ageing by efficiently eliminating damaged and potentially harmful organelles and intracellular protein aggregates. Here, we show that the abundance of phosphatidylethanolamine (PE) positively regulates autophagy.

Phosphatidylethanolamine and Lysophosphatidylethanolamine

Journal of Pharmacy and Pharmacology, 1963
Abstract Phosphatidylethanolamine and Lysophosphatidylethanolamine belong to a group of phospholipids generally termed cephalins. The phospholipids are universally distributed among living organisms and are thought to be essential components of cell membranes.

Lipid bilayer composition influences small multidrug transporters [PDF]

, 2008
Background: Membrane proteins are influenced by their surrounding lipids. We investigate the effect of bilayer composition on the membrane transport activity of two members of the small multidrug resistance family; the Escherichia coli transporter, EmrE

Phosphatidylethanolamine is externalized at the surface of microparticles [PDF]

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2012
Microparticles (MPs) are membrane-bound vesicles shed normally or as a result of various (pathological) stimuli. MPs contain a wealth of bio-active macromolecules. Aminophospholipid phosphatidylserine (PS) is present on the surface of many MPs. As PS and phosphatidylethanolamine (PE) are related, yet distinct aminophospholipids, the purpose of this ...

Membrane phospholipid redistribution in cancer micro-particles and implications in the recruitment of cationic protein factors

Journal of Extracellular Vesicles, 2014
Cancer cell-derived micro-particles (MPs) play important regulatory roles on cellular and system levels. These activities are attributed in part to protein factors carried by MPs.

Phosphatidylethanolamine Levels and Regulation of Phosphatidylethanolamine N- Methyltransferase

Journal of Biological Chemistry, 1989
The activity of phosphatidylethanolamine (PE) N-methyltransferase in liver microsomes, measured using endogenous microsomal PE as a substrate, was elevated 2-fold in the choline-deficient state. However, methyltransferase activity assayed in the presence of a saturating concentration of phosphatidyl-N-mono-methylethanolamine or microsomal PE was ...

Serum phospholipids during aging: A comprehensive systematic review of cross-sectional and case-control studies [PDF]

Health Promotion Perspectives
Background: The lipidome, as a subset of metabolomics, can undergo significant variations due to several factors, including the aging process. Therefore, this study aims to summarize the relationship between aging and alterations in plasma phospholipids.

A rapid phospholipase D assay using zirconium precipitation of anionic substrate phospholipids: application to N-acylethanolamine formation in vitro

Journal of Lipid Research, 2000
Activation of phospholipase D (PLD) is involved in a number of signal transduction pathways in eukaryotic cells. The most common method for determination of PLD activity in vitro involves incubation with a radiolabeled substrate and lipid extraction ...
