Fifty years of lyase and a moment of truth: sphingosine phosphate lyase from discovery to disease[S]

Journal of Lipid Research, 2019
Sphingosine phosphate lyase (SPL) is the final enzyme in the sphingolipid degradative pathway, catalyzing the irreversible cleavage of long-chain base phosphates (LCBPs) to yield a long-chain aldehyde and ethanolamine phosphate (EP).

Generierung von Sphingosin-1-Phosphat durch apoptotische Zellen und dessen Einfluss auf die Polarisierung von Makrophagen während der Tumorentwicklung [PDF]

, 2008
The removal of apoptotic cells (AC) can be regarded as an integral component of the program to terminate inflammation. Clearance of AC by professional phagocytes such as macrophages induces an anti-inflammatory phenotype in the latter ones.

S1P-S1PR1 Signaling: the “Sphinx” in Osteoimmunology

Frontiers in Immunology, 2019
The fundamental interaction between the immune and skeletal systems, termed as osteoimmunology, has been demonstrated to play indispensable roles in the maintenance of balance between bone resorption and formation. The pleiotropic sphingolipid metabolite,

The suppression of the SPHK1/S1P/S1PR3 signaling pathway diminishes EGFR activation and increases the sensitivity of non-small cell lung cancer to gefitinib

Current Research in Pharmacology and Drug Discovery
Non-small-cell lung cancer (NSCLC) represents a predominant histological subtype of lung cancer, characterized by high incidence and mortality rates.

Insulin protects apoptotic cardiomyocytes from hypoxia/reoxygenation injury through the sphingosine kinase/sphingosine 1-phosphate axis.

PLoS ONE, 2013
ObjectiveExperimental and clinical studies have shown that administration of insulin during reperfusion is cardioprotective, but the mechanisms underlying this effect are still unknown.

Sphingosine-1-phosphate receptor 3 mediates sphingosine-1-phosphate induced release of weibel-palade bodies from endothelial cells.

PLoS ONE, 2014
Sphingosine-1-phosphate (S1P) is an agonist for five distinct G-protein coupled receptors, that is released by platelets, mast cells, erythrocytes and endothelial cells.

Sphingosine 1-phosphate signalling in mammalian cells [PDF]

, 2000
Sphingosine 1-phosphate is formed in cells in response to diverse stimuli, including growth factors, cytokines, G-protein-coupled receptor agonists, antigen, etc. Its production is catalysed by sphingosine kinase, while degradation is either via cleavage

A facile enzymatic synthesis of sphingosine-1-phosphate and dihydrosphingosine-1-phosphate.

Journal of Lipid Research, 1989
A procedure is described to prepare sphingosine-1-phosphate by treatment of sphingosylphosphocholine with phospholipase D, isolated from Streptomyces chromofuscus.

Antagonizing the S1P-S1P3 Axis as a Promising Anti-Angiogenic Strategy

Metabolites
Background: Angiogenesis, the process of new blood vessel formation, is critically regulated by a balance of pro- and anti-angiogenic factors. This process plays a central role in tumor progression and is modulated by tumor cells. Sphingosine-1-phosphate

Mechanisms of sphingosine and sphingosine 1-phosphate generation in human platelets

Journal of Lipid Research, 2005
The bioactive molecule sphingosine 1-phosphate (S1P) is abundantly stored in platelets and can be released extracellularly. However, although they have high sphingosine (Sph) kinase activity, platelets lack the de novo sphingolipid biosynthesis necessary
