Activation of arachidonoyl-phosphatidylinositol and phosphatidylcholine turnover by K(+)-evoked stimulation of brain synaptosomes.

Neurochemistry international

Majewska MD, Sun GY.
PMID: 20487897
Neurochem Int. 1982;4(5):427-33. doi: 10.1016/0197-0186(82)90086-9.

The turnover of arachidonoyl groups in synaptosomal phospholipids after stimulation by K(+) was examined. Raising the K(+) concentration in the incubation medium from 5 to 55 mM caused a rapid hydrolysis of labeled arachidonate from the synaptosomal phospholipids. Under...

Diacylglycerol kinase and lipase activities in rat brain subcellular fractions.

Neurochemistry international

Strosznajder J, Wikiel H, Kelleher JA, Leu VS, Sun GY.
PMID: 20493049
Neurochem Int. 1986;8(2):213-21. doi: 10.1016/0197-0186(86)90166-x.

Phosphatidic acid synthesis via diacylglycerol kinase and free fatty acid release via diacylglycerol lipase were investigated in rat brain subcellular fractions using membrane-bound [I-(14)C]arachidonoyl-diacylglycerol as substrate. Labeled diacylglycerol was generated by incubating brain membranes containing [I-(14)C]arachidonoyl-phosphatidylinositols in the presence...

Front Microbiol. 2017 Oct 10;8:1954. doi: 10.3389/fmicb.2017.01954. eCollection 2017.

Zika virus (ZIKV) infection has recently emerged as a major concern worldwide due to its strong association with nervous system malformation (microcephaly) of fetuses in pregnant women infected by the virus. Signs and symptoms of ZIKV infection are often...

Locating Carbon-Carbon Double Bonds in Unsaturated Phospholipids by Epoxidation Reaction and Tandem Mass Spectrometry.

Analytical chemistry

Cao W, Ma X, Li Z, Zhou X, Ouyang Z.
PMID: 30095894
Anal Chem. 2018 Sep 04;90(17):10286-10292. doi: 10.1021/acs.analchem.8b02021. Epub 2018 Aug 23.

The presence of carbon-carbon double bonds (C═Cs) in unsaturated phospholipids is closely related to lipid conformations and physiochemical activities. Previously, we have demonstrated that epoxidation reaction facilitated by low-temperature plasma (LTP) enabled the structural analysis of unsaturated fatty acids...

Hyccin/FAM126A deficiency reduces glial enrichment and axonal sheath, which are rescued by overexpression of a plasma membrane-targeting PI4KIIIα in Drosophila.

Biochemical and biophysical research communications

Zhang Q, Zhang B, Lim NKH, Zhang X, Meng S, Nyengaard JR, Huang F, Wang WA.
PMID: 34894559
Biochem Biophys Res Commun. 2021 Dec 03;589:71-77. doi: 10.1016/j.bbrc.2021.11.106. Epub 2021 Dec 03.

Hyccin/FAM126A mutations are linked to hypomyelination and congenital cataract disease (HCC), but whether and how Hyccin/FAM126A deficiency causes hypomyelination remains undetermined. This study shows Hyccin/FAM126A expression was necessary for the expression of other components of the PI4KIIIα complex in...

PURPOSE: The purpose of this study was to understand the impact of Demodex infection in the lipid component of meibum in patients.METHODS: The meibum samples were collected from four groups of subjects: (1) Demodex-negative with non-MGD (D-M-; n =...

Hepatic deletion of Mboat7 (LPIAT1) causes activation of SREBP-1c and fatty liver.

Journal of lipid research

Xia M, Chandrasekaran P, Rong S, Fu X, Mitsche MA.

J Lipid Res. 2021;62:100031. doi: 10.1194/jlr.RA120000856. Epub 2021 Feb 06.

Genetic variants that increase the risk of fatty liver disease and cirrhosis have recently been identified in the proximity of membrane-bound O-acyltransferase domain-containing 7 (MBOAT7). To elucidate the link between these variants and fatty liver disease, we characterized Mboat7...

The Vacuolar Protein Sorting-38 Subunit of the .

The family of phosphatidylinositols (PtdIns) plays essential roles in membrane identity and intracellular trafficking events. In animals and yeast, PtdIn-3-phosphate, which is particularly important for endosomal sorting, lysosomal/vacuolar transport and autophagy, is assembled by two conserved kinase complexes comprised...
