Lipidomic Comparison of Detergent-Soluble and Detergent-Resistant Lipid Domains Isolated From Rat Cerebellum and the Effect of Hypoxia-Ischemia Using UPLC-HDMS<sup>E</sup>. [PDF]
J Mass SpectromABSTRACT Hypoxic ischemic encephalopathy (HIE) due to insufficient oxygen or blood flow to the brain can result in inflammation, impaired neurodevelopment, or death. Changes to microdomain lipid composition may contribute to altered structure and function of key regulatory processes; however, knowledge regarding changes to membrane lipid composition ...

SnapShot: Bioactive Lysophospholipids
Cell, 2012 Lysophosphatidic acid (LPA; monoacyl-glycerol-3-phosphate) and sphingosine 1-phosphate (S1P) are bioactive lysophospholipids that regulate critical biological functions and disease processes. LPA and S1P act on distinct G protein-coupled receptors (GPCRs) that initiate multiple signaling cascades in many cell types.

Polarization of macrophages toward M2 phenotype is favored by reduction in iPLA2β (group VIA phospholipase A2)* [PDF]
, 2016 Macrophages are important in innate and adaptive immunity. Macrophage participation in inflammation or tissue repair is directed by various extracellular signals and mediated by multiple intracellular pathways.

Acute Hypercapnia/Ischemia Alters the Esterification of Arachidonic Acid and Docosahexaenoic Acid Epoxide Metabolites in Rat Brain Neutral Lipids. [PDF]
, 2020 In the brain, approximately 90% of oxylipins are esterified to lipids. However, the significance of this esterification process is not known. In the present study, we (1) validated an aminopropyl solid phase extraction (SPE) method for separating ...

Metabolic reprogramming ensures cancer cell survival despite oncogenic signaling blockade [PDF]
, 2017 There is limited knowledge about the metabolic reprogramming induced by cancer therapies, and how this contributes to therapeutic resistance. Here we show that although inhibition of PI3K-AKT-mTOR signaling markedly decreased glycolysis and restrained

Lysophospholipid receptors: Signalling, pharmacology and regulation by lysophospholipid metabolism
Biochimica et Biophysica Acta (BBA) - Biomembranes, 2007 The lysophospholipids, sphingosine-1-phosphate (S1P), lysophosphatidic acid (LPA), sphingosylphosphorylcholine (SPC) and lysophosphatidylcholine (LPC), activate diverse groups of G-protein-coupled receptors that are widely expressed and regulate decisive cellular functions.

Lysophospholipid mediators in the vasculature [PDF]
Experimental Cell Research, 2015 Acting through cell surface receptors, “extracellular” lysophosphatidic acid (LPA) influences cell growth, differentiation, apoptosis and development in a wide spectrum of settings [1–5]. Within the vasculature, smooth muscle cells [6, 7], endothelial cells [8] and platelets [9, 10] display notable responses to LPA [11, 12], which likely regulate blood

The patatin-containing phospholipase A pPLAIIα modulates oxylipin formation and water loss in Arabidopsis thaliana [PDF]
, 2012 The patatin-related phospholipase A (pPLA) hydrolyzes membrane glycerolipids to produce monoacyl compounds and free fatty acids. Phospholipids are cleaved by pPLAIIα at the sn-1 and sn-2 positions, and galactolipids, including those containing ...

Lysophospholipids in laboratory medicine
Proceedings of the Japan Academy, Series B, 2018 Lysophospholipids (LPLs), such as lysophosphatidic acid (LPA), sphingosine 1-phosphate (S1P), and lysophosphatidylserine (LysoPS), are attracting attention as second-generation lipid mediators. In our laboratory, the functional roles of these lipid mediators and the mechanisms by which the levels of these mediators are regulated in vivo have been ...
