Endothelial differentiation gene receptors in pancreatic islets and INS-1 cells.
The endothelial differentiation gene (EDG) receptors are a class of G protein-coupled receptors. EDG-1, -3, -5, -6, and -8 bind the bioactive lipid sphingosine-1-phosphate (SPP) as the primary signaling ligand. EDG-2, -4, and -7 bind the ligand lysophosphatidic acid. EDG-1, -2, -3, -5, -6, and -7, but not -8, mRNAs were expressed in isolated rat pancreatic islets, whereas INS-1 insulinoma cells...
متن کاملSphingosine kinase activity and sphingosine-1 phosphate production in rat pancreatic islets and INS-1 cells: response to cytokines.
Sphingosine-1 phosphate (S1P) is a bioactive sphingolipid with the potential to mobilize Ca2+, to inhibit apoptosis, and to promote mitogenesis. Sphingosine kinase (SPHK) and S1P were characterized in INS-1 insulinoma cells and isolated rat islets of Langerhans. SPHK activity increased in INS-1 cell homogenates treated with interleukin-1beta (IL-1beta) or tumor necrosis factor-alpha (TNF-alpha)...
متن کاملPancreatic islets activate portal vein endothelial cells in vitro.
This study assessed the active role of the portal vein endothelium in the functional loss of pancreatic islet (PI) grafts, considered in the context of PI transplantation for treatment of type I diabetes mellitus. We hypothesized that PI engraftment may be jeopardized by portal vein endothelial cell-induced activation of host T cells. We designed an in vitro system using portal vein endothelial...
متن کاملIntraislet endothelial cells contribute to revascularization of transplanted pancreatic islets.
Pancreatic islet transplantation is an emerging therapy for type 1 diabetes. To survive and function, transplanted islets must revascularize because islet isolation severs arterial and venous connections; the current paradigm is that islet revascularization originates from the transplant recipient. Because isolated islets retain intraislet endothelial cells, we determined whether these endothel...
متن کاملDifferent secretory response of pancreatic islets and insulin secreting cell lines INS-1 and INS-1E to osmotic stimuli.
Objective of this study was to characterize osmotically-induced insulin secretion in two tumor cell lines. We compared response of freshly isolated rat pancreatic islets and INS-1 and INS-1E tumor cell lines to high glucose, 30 % hypotonic medium and 20 % hypertonic medium. In Ca(2+)-containing medium glucose induced insulin release in all three cell types. Hypotonicity induced insulin secretio...
