Sphingosine-1-phosphate
Inflammatory bowel disease is associated with an increased risk of colorectal cancer. Colitis-associated cancer is a classical inflammation-driven cancer in which constitutive NFκB and STAT3 activation drive tumorigenesis. Recent findings published by Liang et al. in Cancer Cell demonstrate that sphingosine kinase 1 (SphK1)-mediated upregulation of sphingosine-1-phosphate (S1P) drives a persist...
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 کاملTranscriptional modulation of SLC26A3 (DRA) by sphingosine-1-phosphate.
SLC26A3 or Downregulated in adenoma (DRA) is the major Cl(-)/HCO3 (-) exchanger involved in electroneutral NaCl absorption in the mammalian intestine. Alterations in DRA function and expression have been implicated in diarrheal diseases associated with inflammation or infection. Therefore, agents that upregulate DRA activity may serve as potential antidiarrheals. In this regard, sphingosine-1-p...
متن کاملSphingosine-1-Phosphate Receptor 3 Mediates Sphingosine-1-Phosphate Induced Release of Weibel-Palade Bodies from Endothelial Cells
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. S1P promotes endothelial cell barrier function and induces release of endothelial cell-specific storage-organelles designated Weibel-Palade bodies (WPBs). S1P-mediated enhancement of endothelial cell barrier function is depende...
متن کاملResveratrol Stimulates Sphingosine-1-Phosphate Signaling of Cathelicidin Production
We recently discovered a regulatory mechanism that stimulates the production of the multifunctional antimicrobial peptide cathelicidin antimicrobial peptide (CAMP). In response to subtoxic levels of ER stress, increased sphingosine-1-phosphate (S1P) production activates an NFκBC/EBPα-dependent pathway that enhances CAMP production in cultured human keratinocytes. As the multifunctional stilben...
