Effects of Sphingomyelin-Containing Milk Phospholipids on Skin Hydration in UVB-Exposed Hairless Mice

Molecules, 2022
Reactive oxygen species (ROS) generated by ultraviolet (UV) exposure cause skin barrier dysfunction, which leads to dry skin. In this study, the skin moisturizing effect of sphingomyelin-containing milk phospholipids in UV-induced hairless mice was ...

The Multigenic Sphingomyelin Synthase Family [PDF]

Journal of Biological Chemistry, 2006
Sphingomyelin (SM)3 is a vital component of cellular membranes in organisms ranging from mammals to protozoa. Its production involves the enzymatic transfer of a phosphocholine head group fromphosphatidylcholine to ceramide, yielding diacylglycerol in the process.

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 ...

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.

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).
