Carbachol stimulation of phospholipase A2 and insulin secretion in pancreatic islets.
TLDR
It is shown, for the first time, that the muscarinic agonist carbachol, at concentrations which stimulate insulin secretion, causes a rapid and nearly 3-fold increase in arachidonic acid accumulation in islets. Expand
Inhibition of phospholipase A2 and insulin secretion in pancreatic islets.
TLDR
The observations suggest that glucose-induced arachidonate increase is essential for insulin secretion, which is specific for phospholipase A2. Expand
Muscarinic Regulation of Alzheimer's Disease Amyloid Precursor Protein Secretion and Amyloid β-Protein Production in Human Neuronal NT2N Cells (*)
TLDR
The results suggest that APP-S secretion and Aβ production in NT2N neurons are regulated by the muscarinic/phospholipase C signal transduction pathway. Expand
Transient activation of calcium-dependent phospholipase A2 by insulin secretagogues in isolated pancreatic islets.
TLDR
It is suggested that activation of islet Ca(2+)-dependent phospholipase A2 may be important in a distal process of insulin secretion, such as secretory granule exocytosis. Expand
U-73122 does not specifically inhibit phospholipase C in rat pancreatic islets and insulin-secreting beta-cell lines.
TLDR
Observations suggest that U-73122 does not specifically inhibit phospholipase C in insulin-secreting cells. Expand
Fuel secretagogue stimulation of arachidonic acid accumulation in fresh and cultured pancreatic islets
TLDR
It is shown that non-metabolizable analogs of glucose which do not stimulate insulin secretion fail to cause significant accumulation of unesterified arachidonic acid in pancreatic islets. Expand
Glucose and carbachol synergistically stimulate phosphatidic acid accumulation in pancreatic islets.
TLDR
The data suggest that phosphatidic acid may have a central role in insulin secretion as an intracellular mediator, and possible mechanisms include de novo synthesis from glucose and/or activation of phospholipase D. Expand
