Identification of biosynthetic precursors for the endocannabinoid anandamide in the rat brain

Journal of Lipid Research, 2008
Anandamide is an endogenous signaling lipid that binds to and activates cannabinoid receptors in the brain and peripheral tissues. The endogenous precursors of ananda­mide, N-arachidonoyl phosphatidylethanolamines (NArPEs), are a family of complex ...

DioxolaneA3-phosphatidylethanolamines are generated by human platelets and stimulate neutrophil integrin expression

Redox Biology, 2017
Activated platelets generate an eicosanoid proposed to be 8-hydroxy-9,10-dioxolane A3 (DXA3). Herein, we demonstrate that significant amounts of DXA3 are rapidly attached to phosphatidylethanolamine (PE) forming four esterified eicosanoids, 16:0p, 18:0p,

Fatty liver induction: inverse relationship between hepatic neutral lipid accumulation and dietary polyunsaturated fatty acids in orotic acid-fed rats

Journal of Lipid Research, 1972
The levels of hepatic neutral lipids in the orotic acid-fed rat were inversely related to the dietary levels of polyunsaturated fatty acids, as in the choline-deficient rat.

Plasma Lipidomics Identifies Unique Lipid Signatures and Potential Biomarkers for Patients With Aortic Dissection

Frontiers in Cardiovascular Medicine, 2021
Aortic dissection (AD) is a catastrophic cardiovascular emergency with a poor prognosis, and little preceding symptoms. Abnormal lipid metabolism is closely related to the pathogenesis of AD.

Physiology of cold-acclimation in non-diapausing adults of Pyrrhocoris apterus (Heteroptera)

European Journal of Entomology, 2002
Chill tolerance (time of survival at -5°C) increased in non-diapausing (reproducing) adults of Pyrrhocoris apterus after a gradual, 4-week-long decrease in ambient temperature from 25° to 0°C.

Untargeted UHPLC-TOF/MS Lipidomic Analysis for the Investigation of Egg Yolks after Xylanase Supplementation of the Diet of Laying Hens

Metabolites, 2023
Xylanase supplementation of diets is used to enhance nutrient digestibility in monogastrics which lack necessary enzymes for non-starch polysaccharide degradation.

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 ...

Ion Mobility–Mass Spectrometry Approach for the Comparison of Sheep and Goat Milk Lipidomes

Applied Sciences, 2023
In this work, we report an analytical procedure to investigate the lipid compositions of sheep and goat milk. This approach is based on an ion mobility–high-resolution mass spectrometric method to facilitate the identification of complex lipid species ...

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.
