To test this hypothesis further, we examined the effects of phenylephrine, an agonist that increases diacylglycerol and protein kinase C activity through phospholipase C activation.

Digestion of the purified molecule with phosphatidylinositol-specific phospholipase C generated a material that activated both pyruvate dehydrogenase and low-Km cyclic AMP phosphodiesterase.

Such an activation of phospholipase C would result in the formation of 1,4,5-inositol trisphosphate, a release of intracellular calcium and then release of insulin to the extracellular space.

Incubation of isolated cardiac myocytes from rat hearts with heparin or phosphatidylinositol-specific phospholipase C (PLC) resulted in the release of lipoprotein lipase (LPL) into the medium.

Treatment of the cells with phospholipase C at concentrations up to 3.4 U/ml did not affect specific insulin binding, but reduced insulin-stimulated receptor phosphorylation by 50%.

|
Insulin-stimulated phosphorylation of pp 185, the presumed endogenous substrate for the insulin receptor kinase, was also reduced following phospholipase C treatment, with an almost complete loss of insulin stimulation after exposure of cells to enzyme at concentrations as low as 0.6 U/ml.

In contrast to these effects of phospholipase C on intact cells, receptor autophosphorylation was not affected in insulin receptors purified on wheat germ agglutinin-agarose from phospholipase C treated cells.

Receptor-medicated phospholipase C (PLC) activation and hydrolysis of phosphatidylinositol bisphosphate (PIP2) accompanies platelet activation.

These findings support the conclusion that DAG is principally derived from phosphoinositides by phospholipase C hydrolysis, but a minor fraction could be derived from phosphatidylcholine either by the action of phospholipase C or via phospholipase D and PA phosphatase.

Alterations of liver membrane phospholipase C activity in NIDDM, therefore, may reflect diabetic pathology other than the insulin resistance associated with this disease.

While it is known that this receptor is coupled to phospholipase C, like many other phospholipase C-activating receptors, little is known about regulation of the NMB-R subsequent to agonist stimulation.

These results suggest that sulphonylureas and insulin induce suppression of thrombin-induced activation of phospholipase C, which mediates hydrolysis of PIP and PIP2 and production of PA, which leads to inhibition of platelet aggregation.

Whereas the PDGFr associated with PtdIns 3'-kinase, ras-GAP, GRB-2, and phospholipase C gamma, only GRB-2 and PtdIns 3'-kinase associated with IRS-1.

Moreover, PDGF, but not insulin, caused tyrosine phosphorylation of phospholipase C gamma in HIR 3.5 cells.

G alpha q is the alpha subunit of one of the heterotrimeric GTP-binding proteins that mediates stimulation of phospholipase C beta.

The morphogen-induced decline in Gialpha2 is shown to trigger activation of phospholipase C, thereby activating protein kinase C, MAP kinase, and cell progression to primitive endoderm.

Cholinergic agonists amplify insulin release by several pathways, including activation of phospholipase C, which hydrolyzes membrane polyphosphoinositides.

Phospholipase C activating agents (carbachol, CCK-8), adenylate cyclase activating agents (secretin, VIP), TPA and the calcium ionophore, A23187, all inhibited the binding of 125I-BH-SP and it was due to inhibition of ligand internalization with no change in surface bound parameters.

We speculate that hyperglycaemia could directly contribute to a loss of CD59 and CD55 molecules through a calcium-dependent phosphoinositol-specific phospholipase C activation and subsequent regulation of cell wall expression of GPI-anchored proteins.

Pharmacological inhibitors of the Rho small GTPase (C3 exoenzyme), phospholipase C (U-73122), cyclooxygenases (SC-560, NS-398), and the thromboxane A2 receptor (TXA2-R) antagonist SQ-295 completely abolished invasion induced by intestinal trefoil factor, pS2, and src in kidney and colonic epithelial cells MDCKts.src and PCmsrc.

Diacylglycerol (DG) was synthesized from glucose and was not affected by phospholipase C (PLC) inhibition under resting conditions in normal glucose.

ERK phosphorylation was not affected by exposure to the Ca2+ chelator BAPTA-AM but inhibition of protein kinase C (PKC) with GF109203X, inhibition of Src kinase with PP1 (5 microM) and inhibition of phospholipase C (PLC) with U73122/U73343 (5 microM) all reduced ERK phosphorylation in response to glycated LDL.

Stimulation occurs within minutes by an increase in apical GLUT2, which correlates with reciprocal regulation of T1R2, T1R3 and alpha-gustducin versus T1R1, transducin and phospholipase C beta2.

In these rats, angiotensin II caused significantly higher accumulation of inositol trisphosphate (IP3) and phospholipase C (PLC) activation which was sensitive to blockade by AT1 but not to AT2 antagonist.

Activation of the kisspeptin receptor by kisspeptin is via coupling to G(q/11) and the phospholipase C pathway, causing Ca(2+) mobilization.

Furthermore, pretreatment of MIN-6 cells with phospholipase C (PLC) inhibitors with different mechanisms of action, U-73122 and neomycin, and knockdowns of the IL-6 receptor and PLC-?(1), but not with a protein kinase A inhibitor, H-89, inhibited IL-6-induced enhancement of GSIS.
