Sphingomyelin metabolism is involved in the differentiation of MDCK cells induced by environmental hypertonicity [PDF]

open access: yes, 2015
Sphingolipids (SLs) are relevant lipid components of eukaryotic cells. Besides regulating various cellular processes, SLs provide the structural framework for plasma membrane organization.

Intestinal Acid Sphingomyelinase Protects From Severe Pathogen-Driven Colitis [PDF]

open access: yes, 2019
Inflammatory diseases of the gastrointestinal tract are emerging as a global problem with increased evidence and prevalence in numerous countries. A dysregulated sphingolipid metabolism occurs in patients with ulcerative colitis and is discussed to ...

Regulation of the threshold for lipoprotein-induced acyl-CoA:cholesterol O-acyltransferase stimulation in macrophages by cellular sphingomyelin content.

open access: yesJournal of Lipid Research, 1994
Macrophage acyl-CoA:cholesterol O-acyltransferase (ACAT), a key enzyme in atheroma foam cell formation, is stimulated by lipoproteins only after a “threshold” amount of cholesterol has accumulated in the cell.

Ceramide is a Mediator of Apoptosis in Retina Photoreceptors [PDF]

open access: yes, 2006
PURPOSE. The precise mechanisms involved in photoreceptor apoptosis are still unclear. We here investigated the role of ceramide, a sphingolipid precursor that induces apoptosis upon cellular stress, in activating this death in photoreceptors.

Essential lipid autacoids rewire mitochondrial energy efficiency in metabolic dysfunction‐associated fatty liver disease

open access: yesHepatology, EarlyView., 2022
Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.

Optimization of Giant Unilamellar Vesicle Electroformation for Phosphatidylcholine/Sphingomyelin/Cholesterol Ternary Mixtures

open access: yesMembranes, 2022
Artificial vesicles are important tools in membrane research because they enable studying membrane properties in controlled conditions. Giant unilamellar vesicles (GUVs) are specially interesting due to their similarity in size to eukaryotic cells.

Acid Sphingomyelinase Regulates the Localization and Trafficking of Palmitoylated Proteins [PDF]

open access: yes, 2019
In human, loss of Acid Sphingomeylinase (ASM/SMPD1) causes Niemann-Pick Disease, type A. ASM hydrolyzes sphingomyelins to produce ceramides but protein targets of ASM remain largely unclear. ...

Molecular rheometry: direct determination of viscosity in L-o and L-d lipid phases via fluorescence lifetime imaging [PDF]

open access: yes, 2013
Understanding of cellular regulatory pathways that involve lipid membranes requires the detailed knowledge of their physical state and structure. However, mapping the viscosity and diffusion in the membranes of complex composition is currently a non ...

Membrane properties of sphingomyelins [PDF]

open access: yesFEBS Letters, 2002
Sphingomyelin and phosphatidylcholine are important components in the external leaflet of cellular plasma membranes. In this review we compare the structure of these lipid molecules, with emphasis on the differences in hydrogen bonding capacity and membrane properties that arise from the small but significant differences in molecular structure.

Sphingomyelin and GM1 Influence Huntingtin Binding to, Disruption of, and Aggregation on Lipid Membranes [PDF]

open access: yes, 2018
Huntington disease (HD) is an inherited neurodegenerative disease caused by the expansion beyond a critical threshold of a polyglutamine (polyQ) tract near the N-terminus of the huntingtin (htt) protein. Expanded polyQ promotes the formation of a variety
