Metabolism of sphingolipids by normal and atherosclerotic aorta of squirrel monkeys

Journal of Lipid Research, 1970
We studied the synthesis and hydrolysis of sphingomyelin by homogenates of aortic intima plus inner media from normal squirrel monkeys and from monkeys with nutritionally-induced atherosclerosis (6-10 mo on a semi-purified diet containing butter and ...

Novel Lipids to Regulate Obesity and Brain Function: Comparing Available Evidence and Insights from QSAR In Silico Models

Foods, 2023
Lipid molecules, such as policosanol, ergosterol, sphingomyelin, omega 3 rich phosphatidylcholine, α-tocopherol, and sodium butyrate, have emerged as novel additions to the portfolio of bioactive lipids.

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

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

Genetic Determinants of Circulating Sphingolipid Concentrations in European Populations [PDF]

, 2009
Sphingolipids have essential roles as structural components of cell membranes and in cell signalling, and disruption of their metabolism causes several diseases, with diverse neurological, psychiatric, and metabolic consequences.

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

Journal 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.

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

, 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 ...

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.

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 ...

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

Membranes, 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.

Chlamydial infection from outside to inside [PDF]

, 2019
Chlamydia are obligate intracellular bacteria, characterized by a unique biphasic developmental cycle. Specific interactions with the host cell are crucial for the bacteria's survival and amplification because of the reduced chlamydial genome.
