The present report was addressed to study the influence of sphingolipid metabolism in determining cellular fate. In nonstimulated proliferating Madin-Darby canine kidney (MDCK) cells, sphingolipid de novo synthesis is branched mainly to a production of sphingomyelin and ceramide, with a minor production of sphingosylphosphocholine, ceramide 1-phosphate, and sphingosine 1-phosphate. Experiments ...
Sphingosine kinase is a key enzyme in sphingolipid metabolism, catalysing the conversion of sphingosine or dihydrosphingosine into sphingosine-1-phosphate or dihydrosphingosine-1-phosphate respectively. In mammals, sphingosine-1-phosphate is a powerful signalling molecule regulating cell growth, differentiation, apoptosis and immunity. Functions of sphingosine kinase or sphingosine-1-phosphate ...
Over the last few years, sphingolipids have been identified as potent second messenger molecules modulating cell growth and activation. A newly emerging facet to this class of lipids suggests a picture where the balance between two counterregulatory lipids (as shown in the particular example of ceramide and sphingosine-1-phosphate in T lymphocyte apoptosis) determines the cell fate by setting t...
Extrinsic factors, such as air pollutants and ultraviolet irradiation (UVR), accelerate premature aging, a correlation between levels of skin aging symptoms has been reported. Diesel particulate matter, major source pollution, helps initiate some diseases, including diseases. We recently demonstrated that diesel extract (DPE) activates nicotinamide adenine dinucleotide phosphate (NADPH) oxidase...
OBJECTIVE Oxidized low-density lipoprotein (oxLDL)-induced smooth muscle cell (SMC) proliferation requires the coactivation of various signaling pathways, namely sphingomyelin/ceramide/sphingosine-1-phosphate, epithelial growth factor receptor (EGFR), and phosphoinositide 3-kinase (PI-3K) pathways. This study aimed to clarify the respective role and the hypothetical cross-talk between sphingomy...
