Sphingolipids and cholesterol modulate membrane susceptibility to cytosolic phospholipase A2

Journal of Lipid Research, 2000
Modulation of cytosolic phospholipase A2 (cPLA2) activity by sphingomyelin (SPH), ceramide (Cer), and cholesterol (Chol) was investigated in CHO-2B cells activated by the calcium ionophore A23187 and epinephrine.

Different rates of flux through the biosynthetic pathway for long-chain versus very-long-chain sphingolipids

Journal of Lipid Research, 2020
The backbone of all sphingolipids (SLs) is a sphingoid long-chain base (LCB) to which a fatty acid is N-acylated. Considerable variability exists in the chain length and degree of saturation of both of these hydrophobic chains, and recent work has ...

How do nematodes transfer phosphorylcholine to carbohydrates? [PDF]

, 2010
An unusual aspect of the biology of nematodes is the attachment of phosphorylcholine (PC) to carbohydrate. The attachment appears to play an important role in nematode development and, in some parasitic species, in immunomodulation.

The impact of sphingomyelin on the pathophysiology and treatment response to olipudase alfa in acid sphingomyelinase deficiency

Genetics in Medicine Open
Acid sphingomyelinase deficiency (ASMD) is a rare progressive genetic disorder caused by pathogenic variants in the SMPD1 gene causing low or absent activity of the enzyme acid sphingomyelinase, resulting in subsequent accumulation of its substrate ...

Sphingomyelins and ent-Sphingomyelins Form Homophilic Nano-Subdomains within Liquid Ordered Domains [PDF]

Biophysical Journal, 2020
Sphingomyelin (SM), a major component of small domains (or lipid rafts) in mammalian cell membranes, forms a liquid-ordered phase in the presence of cholesterol (Cho). However, the nature of molecular interactions within the ordered SM/Cho phase remains elusive.

Spatial Detection of Microsphere Polystyrene Plastics and Molecular Remodeling within a Full‐Body Mouse with MALDI Trapped Ion Mobility Mass Spectrometry Imaging

Angewandte Chemie, EarlyView.
Orally administered polystyrene microplastics accumulate in murine tissues and are detected using MALDI‐MSI with TIMS. Lipid profiling reveals decreases in hexosylceramides, sphingomyelins, and ether‐linked phospholipids, indicating altered metabolism.

Sphingomyelin is involved in regulating UCP1-mediated nonshivering thermogenesis

Journal of Lipid Research
Adipogenesis is one of the major mechanisms for adipose tissue expansion, during which spindle-shaped mesenchymal stem cells commit to the fate of adipocyte precursors and differentiate into round-shaped fat-laden adipocytes.

Quantitative analysis of ceramide molecular species by high performance liquid chromatography

Journal of Lipid Research, 1998
A method was developed for quantitative analysis of molecular species of ceramide (N-acyl-sphingosine) and dihydroceramide (N-acyl sphinganine) by high performance liquid chromatography (HPLC).

Characterization of the small molecule ARC39, a direct and specific inhibitor of acid sphingomyelinase in vitro[S]

Journal of Lipid Research, 2020
Inhibition of acid sphingomyelinase (ASM), a lysosomal enzyme that catalyzes the hydrolysis of sphingomyelin into ceramide and phosphorylcholine, may serve as an investigational tool or a therapeutic intervention to control many diseases.

Atomistic simulations of a multicomponent asymmetric lipid bilayer

, 2012
The cell membrane is inherently asymmetric and heterogeneous in its composition, a feature that is crucial for its function. Using atomistic molecular dynamics simulations, the physical properties of a 3-component asymmetric mixed lipid bilayer system ...
