Sphingosine 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 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 interacts with Survivin pathway to enhance tumorigenesis in cancer cells
Objective(s):Degradation of sphingosine 1-phosphate (S1P), as a bioactive lipid, or deregulation of its production involves in tumor progression, metastasis and chemoresistance. Since the tumor progression effects of S1P and its mechanism in chronic lymphoblastic leukemia and non-small cell lung cancer is not fully understood, we investigated the role and one of the mechanisms of S1P in tumor p...
