Isomers of inositol trisphosphate in exocrine pancreas.
In rat pancreatic acinar cells, the Ca2+-mobilizing receptor-agonist, caerulein, at both maximal and submaximal concentrations, stimulated a rapid, transient, increase in [3H]inositol 1,4,5-trisphosphate [(1,4,5)IP3], followed by a slower, sustained, increase in [3H]inositol 1,3,4-trisphosphate [(1,3,4)IP3]. Neither activation of protein kinase C by phorbol dibutyrate nor prevention of the caer...
متن کاملSecretagogue-induced formation of inositol phosphates in rat exocrine pancreas. Implications for a messenger role for inositol trisphosphate.
The formation of inositol phosphates in response to secretagogues was studied in rat pancreatic acini preincubated with [3H]inositol. Carbachol caused rapid increases in radioactive inositol phosphate, inositol bisphosphate and inositol trisphosphate . This effect was blocked by atropine, and also elicited by caerulein, but not by ionomycin or phorbol dibutyrate. Thus phospholipase C-mediated b...
متن کاملAngiotensin-stimulated production of inositol trisphosphate isomers and rapid metabolism through inositol 4-monophosphate in adrenal glomerulosa cells.
The production and metabolism of inositol phosphates in rat adrenal glomerulosa cells prelabeled with [3H]inositol and stimulated with angiotensin II were analyzed by high-performance anion-exchange chromatography. Exposure to angiotensin II was accompanied by a rapid and substantial decrease in the phospholipid precursor, phosphatidylinositol (PtdIns) 4,5-bisphosphate with only a slight and tr...
متن کاملThe exocrine pancreas
This seminar text reviews various forms of enzyme supplementation used clinically in digestive and absorption disorders. Enzyme supplementation plays an integral role in the management of various digestive disorders, particularly with regard to exocrine pancreatic insufficiency. However, application of enzymes may also be beneficial for other conditions associated with poor digestion including ...
متن کاملMetabolism of inositol 1,4,5-trisphosphate and inositol 1,3,4-trisphosphate in rat parotid glands.
A complete separation of myo-inositol 1,4,5-[4,5-(32)P]trisphosphate prepared from human erythrocytes, and myo-[2-3H]inositol 1,3,4-trisphosphate prepared from carbachol-stimulated rat parotid glands [Irvine, Letcher, Lander & Downes (1984) Biochem. J. 223, 237-243], was achieved by anion-exchange high-performance liquid chromatography. This separation technique was then used to study the metab...
