Abstract

Thrombin exhibited diverse effects on mouse 3T3 fibroblasts. It (a) decreased cAMP in the cell suspension, (b) inhibited adenylate cyclase in the Lubrol-permeabilized cell suspension in a GTP-dependent manner, increased releases of (c) arachidonic acid and (d) inositol from the cell monolayer prelabeled with these labeled compounds, (e) increased /sup 45/Ca/sup 2 +/ uptake into the cell monolayer, and (f) increased /sup 86/Rb/sup +/ uptake into the cell monolayer in a ouabain-sensitive manner. Most of the effects were reproduced by bradykinin, platelet-activating factor, and angiotensin II. The receptors for these agonists are thus likely to be linked to three separate effector systems: the adenylate cyclase inhibition, the phosphoinositide breakdown leading to Ca/sup 2 +/ mobilization and phospholipase A2 activation, and the Na,K-ATPase activation. Among the effects of these agonists, (a), (b), (c), and (e) were abolished, but (d) and (f) were not, by prior treatment of the cells with islet-activating protein (IAP), pertussis toxin, which ADP-ribosylates the Mr = 41,000 protein, the alpha-subunit of the inhibitory guanine nucleotide regulatory protein (Ni), thereby abolishing receptor-mediated inhibition of adenylate cyclase. The effects (a), (c), (d), and (e) of thrombin, but not (b), were mimicked by A23187, a calcium ionophore. The effects ofmore »« less

Inhibition by islet-activating protein, pertussis toxin, of P2-purinergic receptor-mediated iodide efflux and phosphoinositide turnover in FRTL-5 cells

Journal Article Okajima, F; Sho, K; Kondo, Y - Endocrinology; (United States)

Exposure of FRTL-5 thyroid cells to ATP (1 microM to 1 mM) resulted in the stimulation of I- efflux in association with the induction of inositol trisphosphate production and intracellular Ca2+ mobilization. Nonhydrolyzable ATP derivatives, ADP and GTP, were also as effective in magnitude as ATP, whereas neither AMP nor adenosine exerted significant effect on I- efflux, suggesting a P2-purinergic receptor-mediated activation of I- efflux. Treatment of the cells with the islet-activating protein (IAP) pertussis toxin, which ADP-ribosylated a 41,000 mol wt membrane protein, effectively suppressed the phosphoinositide response to ATP in addition to ATP-dependent I- efflux at agonist concentrationsmore »« less

Synthetic peptides corresponding to human follicle-stimulating hormone (hFSH)-beta-(1-15) and hFSH-beta-(51-65) induce uptake of 45Ca++ by liposomes: evidence for calcium-conducting transmembrane channel formation

Journal Article Grasso, P; Santa-Coloma, T; Reichert, Jr, L - Endocrinology; (United States)

We have previously described FSH receptor-mediated influx of 45Ca++ in cultured Sertoli cells from immature rats and receptor-enriched proteoliposomes via activation of voltage-sensitive and voltage-independent calcium channels. We have further shown that this effect of FSH does not require cholera toxin- or pertussis toxin-sensitive guanine nucleotide binding protein or activation of adenylate cyclase. In the present study, we have identified regions of human FSH-beta-subunit which appear to be involved in mediating calcium influx. We screened 11 overlapping peptide amides representing the entire primary structure of hFSH-beta-subunit for their effects on 45Ca++ flux in FSH receptor-enriched proteoliposomes. hFSH-beta-(1-15) and hFSH-beta-(51-65) inducedmore »« less

Multiple effects of phorbol esters on hormone-sensitive adenylate cyclase activity in S49 lymphoma cells

Journal Article Bell, J; Brunton, L - Am. J. Physiol.; (United States)

In S49 lymphoma cells, 12-O-tetradecanoyl phorbol-13-acetate (TPA) enhances adenylate cyclase activity and doubles cAMP accumulation in response to ..beta..-adrenergic stimulation at 37/sup 0/C, putatively via the action of protein kinase C. at 27/sup 0/C, TPA has the opposite effect, inhibiting cAMP production in response to isoproterenol by approx. 25%. TPA also inhibits the response to prostaglandin E/sub 1/ (PGE/sub 1/), another stimulant of hormone-sensitive adenylate cyclase in these cells, by 30% at 37/sup 0/C and almost 50% at 27/sup 0/C. In contrast, TPA enhances responses to forskolin and cholera toxin at both 27 and 37/sup 0/C. In membranes from cellsmore »« less
Stimulus-response coupling in platelets

Thesis/Dissertation Huang, E

To understand the mechanism of stimulus-response coupling in platelets, the potentiating effect of succinate and lithium on platelet activation was examined. The action of succinate was immediate; preincubation with succinate did not lead to desensitization. Succinate was comparable to ADP in lowering cAMP levels previously elevated by PGl/sub 2/. Since inhibition of cAMP is not a prerequisite for platelet activation, the mechanism of potentiation of succinate remains undefined. Lithium has also been shown to inhibit adenylate cyclase in PGl/sub 2/-pretreated platelets. Lithium, however, can also inhibit inositol phosphate (InsP) phosphatase and lead to an accumulation of InsP. In human platelets,more »« less
Characteristics of muscarinic receptors that selectively couple to inhibition of adenylate cyclase or stimulation of phospholipase C on NG108-15 and 1321N1 cells

Miscellaneous Liang, M

The purpose of this dissertation was to establish whether different muscarinic receptor proteins selectively couple to different second messenger response system. Although both second messenger response systems are fully functional in both cell lines, activation of muscarinic cholinergic receptors only results in inhibition of adenylate cyclase in NG108-15 neuroblastoma {times} glioma cells and stimulation of phosphoinositide hydrolysis in 1321N1 human astrocytoma cells. Muscarinic receptors on both cell types were covalently labeled with ({sup 3}H)Propylbenzilylcholine mustard (({sup 3}H)PBCM) and the mobilities of the ({sup 3}H)PBCM-labelled species of both cells were compared by SDS-PAGE. 1321N1 and NG108-15 cells each primarily expressed amore »« less
