Sphingosine 1-phosphate signalling.
Sphingosine 1-phosphate (S1P) is a lipid mediator formed by the metabolism of sphingomyelin. In vertebrates, S1P is secreted into the extracellular environment and signals via G protein-coupled S1P receptors to regulate cell-cell and cell-matrix adhesion, and thereby influence cell migration, differentiation and survival. The expression and localization of S1P receptors is dynamically regulated...
متن کاملSphingosine 1-phosphate signalling in cancer.
There is an increasing body of evidence demonstrating a critical role for the bioactive lipid S1P (sphingosine 1-phosphate) in cancer. S1P is synthesized and metabolized by a number of enzymes, including sphingosine kinase, S1P lyase and S1P phosphatases. S1P binds to cell-surface G-protein-coupled receptors (S1P1-S1P5) to elicit cell responses and can also regulate, by direct binding, a number...
متن کاملIntracellular signalling: Sphingosine-1-phosphate branches out
Recent studies indicate that sphingosine-1-phosphate - known to be an important signalling molecule in animal cells - is involved in Ca(2+)-dependent signalling in yeast and higher plants, raising the likelihood that it is a universal signalling molecule with a diverse range of functions in eukaryotes.
متن کاملSphingosine 1-phosphate signalling in mammalian cells.
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 to produce palmitaldehyde and phosphoethanolamine or by dephosphorylation. In this review we discuss the most recent advances in our understan...
متن کاملSphingosine kinase 1/sphingosine 1-phosphate signalling pathway as a potential therapeutic target of pulmonary hypertension.
Pulmonary hypertension is characterized by extensive vascular remodelling, leading to increased pulmonary vascular resistance and eventual death due to right heart failure. The pathogenesis of pulmonary hypertension involves vascular endothelial dysfunction and disordered vascular smooth muscle cell (VSMC) proliferation and migration, but the exact processes remain unknown. Sphingosine 1-phosph...
