Levels of Arabidopsis thaliana Leaf Phosphatidic Acids, Phosphatidylserines, and Most Trienoate-Containing Polar Lipid Molecular Species Increase during the Dark Period of the Diurnal Cycle

Frontiers in Plant Science, 2012
Previous work has demonstrated that plant leaf polar lipid fatty acid composition varies during the diurnal (dark–light) cycle. Fatty acid synthesis occurs primarily during the light, but fatty acid desaturation continues in the absence of light ...

Untargeted Lipidomics and Chemometric Tools for the Characterization and Discrimination of Irradiated Camembert Cheese Analyzed by UHPLC-Q-Orbitrap-MS

Foods, 2023
In this work, an investigation using UHPLC-Q-Orbitrap-MS and multivariate statistics was conducted to obtain the lipid fingerprint of Camembert cheese and to explore its correlated variation with respect to X-ray irradiation treatment.

Cholestasis alters brain lipid and bile acid composition and compromises motor function in neonatal piglets

Physiological Reports, 2022
Infants with neonatal cholestasis are prone to neurodevelopmental deficits, however, the underlying pathogenesis is unclear. Lipid malabsorption and accumulation of potentially neurotoxic molecules in the blood such as bile acids are important yet ...

Tacrine and its analogues impair mitochondrial function and bioenergetics : a lipidomic analysis in rat brain [PDF]

, 2012
Tacrine is an acetylcholinesterase inhibitor used as cognitive enhancer in Alzheimer's disease treatment. However, the low therapeutic efficiency and the high incidence of side effects have limited its clinical use.

If phosphatidylserine is the death knell, a new phosphatidylserine-specific receptor is the bellringer [PDF]

Cell Death & Differentiation, 2001
Recognition of phosphatidylserine (PtdSer) is essential for engulfment of apoptotic cells by mammalian phagocytes. Engagement of a new phosphatidylserine-specific receptor (PtdSerR) appears to be necessary for uptake of apoptotic cells. Many other mammalian receptors have been described to function in the clearance of apoptotic cells.

Asymmetric incorporation of dietary n-3 fatty acids into membrane aminophospholipids of human erythrocytes.

Journal of Lipid Research, 1994
Dietary supplementation with different classes of polyunsaturate fatty acids is known to result in their incorporation into cell membranes, but the effects of this on eicosanoid formation and other cell functions frequently does not correspond to the ...

Metabolic Heavy Isotope Labeling to Study Glycerophospholipid Homeostasis of Cultured Cells

Bio-Protocol, 2017
Glycerophospholipids consist of a glycerophosphate backbone to which are esterified two acyl chains and a polar head group. The head group (e.g., choline, ethanolamine, serine or inositol) defines the glycerophospholipid class, while the acyl chains ...

Extracellular Vesicles and Thrombosis: Update on the Clinical and Experimental Evidence

International Journal of Molecular Sciences, 2021
Extracellular vesicles (EVs) compose a heterogenous group of membrane-derived particles, including exosomes, microvesicles and apoptotic bodies, which are released into the extracellular environment in response to proinflammatory or proapoptotic stimuli.

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)
