Lysophosphatidylcholine export by human ABCA7

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2017
The ATP-binding cassette transporter A7 (ABCA7), which is highly expressed in the brain, is associated with the pathogenesis of Alzheimer's disease (AD). However, the physiological function of ABCA7 and its transport substrates remain unclear. Immunohistochemical analyses of human brain sections from AD and non-AD subjects revealed that ABCA7 is ...

Synthesis of a Novel Lysophosphatidylcholine

Journal of Natural Products, 2000
The novel lysophosphatidylcholine (1), which naturally occurs in the marine sponge Spirastrella abata and was reported to inhibit cholesterol biosynthesis in the Chang liver cell, has been synthesized in four steps from methyl cis-11-octadecenoate (2).

Association of cholesterol with lysophosphatidylcholine

Chemistry and Physics of Lipids, 1983
With equimolar cholesterol, lysophosphatidylcholine (lysoPC) or 1-ether-2-deoxylyso-phosphatidylcholine (etherdeoxylysoPC) form unilamellar vesicles of identical dimensions. 13C-NMR spectra of such vesicles are interpreted on the premise that suppression of a signal by broadening (i.e.

Endothelins specifically recognize lysophosphatidylcholine micelles

Journal of Peptide Science, 2013
Lysophosphatidylcholine (LPC), a major phospholipid component of oxidized low‐density lipoprotein (ox‐LDL), is implicated in numerous inflammatory diseases, including atherosclerosis. Here, to clarify the relationship between bioactive endothelins (ETs) (which are considered to be potent proinflammatory mediators) and LPC/ox‐LDL, we investigated the ...

Lysophosphatidylcholine metabolism and cardiac arrhythmias

Canadian Journal of Physiology and Pharmacology, 1988
The ability of exogenous lysophosphatidylcholine (LPC) to produce electrophysiological abnormalities in cardiac tissues and cardiac arrhythmias in isolated hearts has been well documented. In this study, the arrhythmogenic nature of LPC in the rat, rabbit, and guinea pig hearts was studied.

Mechanism of Lysophosphatidylcholine-Induced Lysosome Destabilization

Journal of Membrane Biology, 2007
Lysosomal destabilization is critical for the organelle and living cells. Phospholipase A(2 )(PLA(2)) was shown to be able to destabilize lysosomes under some conditions. By what mechanism the enzyme affects lysosomal stability is not fully studied. In this study, we investigated the effects of lysophosphatidylcholine (lysoPC), a PLA(2)-produced lipid ...

Penetration of Lysophosphatidylcholine into the Dermis

The Journal of Dermatology, 1991
AbstractThe ability of Lysophosphatidylcholine (LPC) to penetrate into the dermis and its degradation were investigated in vivo using hairless rats. Phosphatidylcholine (PC) was used as a control. Radioactively labelled LPC and PC were applied on the surface of skin, and the radioactivities of the epidermis and dermis were measured at 8, 24, and 48 ...

Lysophosphatidylcholine Induces Apoptosis in AR42J Cells

Pancreas, 2001
Phospholipase A2 (PLA2) has been suggested to play an important role in the pathogenesis of acute pancreatitis, in part through the PLA2-generated phospholipid by-products, most notably lysophosphatidylcholine (lyso-PC). The effects of lyso-PC on pancreatic acinar cells, other than the induction of necrosis, are poorly characterized.

Inhibition of Membrane Fusion by Lysophosphatidylcholine

Biochemistry, 1994
The ability of lysophosphatidylcholine to inhibit membrane fusion at subsolubilizing concentrations (between 1 and 9 mol % with respect to the membrane lipids) was examined. Fusion between N-methyldioleoylphosphatidylethanolamine (DOPE) large unilamellar vesicles (LUV) and fusion between Sendai virus and N-methyl-DOPE LUV were measured.

[8] Lysophosphatidylcholine acyltransferase

1992
Publisher Summary This chapter discusses lysophosphatidylcholine acyltransferase. Lyso-PC:acyl-CoA acyltransferase activity is detected in various mammalian tissues, bacteria, protozoa, and plants. The transfer of acyl groups from acyl-CoA to 1-acylglycerophosphocholine (1-acyl-GPC) is catalyzed by 1-acyl-GPC: acyl-CoA acyltransferase, whereas ...
