Activation of Ceramidase and Ceramide Kinase by Vanadate via a Tyrosine Kinase–Mediated Pathway

Journal of Pharmacological Sciences, 2010
.: Ceramide, a key molecule in the metabolism of sphingolipids, is converted by ceramidase to sphingosine, and phosphorylated by ceramide kinase to form ceramide-1-phosphate (C1P). In this study, we improved on a method of thin-layer chromatography using

Sphingolipids as emerging mediators in retina degeneration [PDF]

, 2019
The sphingolipids ceramide (Cer), sphingosine-1-phosphate (S1P), sphingosine (Sph), and ceramide-1-phosphate (C1P) are key signaling molecules that regulate major cellular functions.

Advances in determining signaling mechanisms of ceramide and role in disease

Journal of Lipid Research, 2019
Ceramide is a critical bioactive lipid involved in diverse cellular processes. It has been proposed to regulate cellular processes by influencing membrane properties and by directly interacting with effector proteins.

Doxorubicin Affects Testicular Lipids with Long-Chain (C18-C22) and Very Long-Chain (C24-C32) Polyunsaturated Fatty Acids [PDF]

, 2007
Doxorubicin disrupts spermatogenesis by causing apoptosis of spermatogonia and primary spermatocytes. The aim of this study was to examine the effect of this agent on adult rat testicular lipids and their fatty acids.

Novel function of ceramide for regulation of mitochondrial ATP release in astrocytes

Journal of Lipid Research, 2018
We reported that amyloid β peptide (Aβ42) activated neutral SMase 2 (nSMase2), thereby increasing the concentration of the sphingolipid ceramide in astrocytes.

C6-ceramide nanoliposomes target the Warburg effect in chronic lymphocytic leukemia. [PDF]

PLoS ONE, 2013
Ceramide is a sphingolipid metabolite that induces cancer cell death. When C6-ceramide is encapsulated in a nanoliposome bilayer formulation, cell death is selectively induced in tumor models. However, the mechanism underlying this selectivity is unknown.

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

Hepatology, 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.

Feeding Stimulates Sphingosine-1-Phosphate Mobilization in Mouse Hypothalamus. [PDF]

, 2019
Previous studies have shown that the sphingolipid-derived mediator sphingosine-1-phosphate (S1P) reduces food intake by activating G protein-coupled S1P receptor-1 (S1PR1) in the hypothalamus.

Loss of hepatic SMLR1 causes hepatosteatosis and protects against atherosclerosis due to decreased hepatic VLDL secretion

Hepatology, EarlyView., 2022
The role of SMLR1 in lipid metabolism (high fat + cholesterol diet in mice) Abstract Background and Aims The assembly and secretion of VLDL from the liver, a pathway that affects hepatic and plasma lipids, remains incompletely understood. We set out to identify players in the VLDL biogenesis pathway by identifying genes that are co‐expressed with the ...

Apoptotic signaling through CD95 (Fas/Apo-1) activates an acidic sphingomyelinase. [PDF]

, 1994
Intracellular pathways leading from membrane receptor engagement to apoptotic cell death are still poorly characterized. We investigated the intracellular signaling generated after cross-linking of CD95 (Fas/Apo-1 antigen), a broadly expressed cell ...
