Dipalmitoleoylphosphoethanolamine as a PP2A Enhancer Obstructs Insulin Signaling by Promoting Ser/Thr Dephosphorylation of Akt

Cellular Physiology and Biochemistry, 2014
Background/Aims: The phospholipid phosphatidylethanolamine is implicated in the regulation of a variety of cellular processes. The present study investigated the effect of phosphatidylethanolamines such as 1,2-diarachidonoyl-sn-glycero-3 ...

A calcium-dependent acyltransferase that produces N-acyl phosphatidylethanolamines

Nature Chemical Biology, 2016
More than 30 years ago, a calcium-dependent enzyme activity was described that generates N-acyl phosphatidylethanolamines (NAPEs), which are precursors for N-acyl ethanolamine (NAE) lipid transmitters, including the endocannabinoid anandamide.

Comparative changes in sugars and lipids show evidence of a critical node for regeneration in safflower seeds during aging

Frontiers in Plant Science, 2022
During seed aging, there is a critical node (CN) where the population viability drops sharply. Exploring the specific locations of the CN in different species of plants is crucial for understanding the biological storage properties of seeds and refining ...

Bursting of charged multicomponent vesicles subjected to electric pulses [PDF]

, 2009
Strong electric pulses applied to phosphatidylcholine ( PC) giant vesicles induce the formation of pores, which reseal within milliseconds. Here, we study the response of vesicles containing PC and negatively charged lipids like phospatidylglycerol ( PG)

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.

Shotgun Lipidomic Profiling of the NCI60 Cell Line Panel Using Rapid Evaporative Ionization Mass Spectrometry [PDF]

, 2016
Rapid evaporative ionization mass spectrometry (REIMS) was used for the rapid mass spectrometric profiling of cancer cell lines. Spectral reproducibility was assessed for three different cell lines, and the extent of interclass differences and intraclass

Strikingly High Activity of 15-Lipoxygenase Towards Di-Polyunsaturated Arachidonoyl/Adrenoyl-Phosphatidylethanolamines Generates Peroxidation Signals of Ferroptotic Cell Death.

Angewandte Chemie
The vast majority of membrane phospholipids (PLs) include two asymmetrically positioned fatty acyls: oxidizable polyunsaturated fatty acids (PUFA) attached predominantly at the sn2 position, and non-oxidizable saturated/monounsaturated acids (SFA/MUFA ...

Phase behavior of two-component lipid membranes: theory and experiments

, 2012
The structure of the ripple phase of phospholipid membranes remains poorly understood in spite of a large number of theoretical studies, with many experimentally established structural features of this phase unaccounted for.

Phosphatidylethanolamines link ferroptosis and autophagy during appressorium formation of rice blast fungus

Molecular plant pathology
A cell death pathway, ferroptosis, occurs in conidial cells and is critical for formation and function of the infection structure, the appressorium, in the rice blast fungus Magnaporthe oryzae. In this study, we identified an orthologous lysophosphatidic
