Abstract
Carotenoids have been associated with risk reduction for several chronic diseases, including the association of their dietary intake/circulating levels with reduced incidence of obesity, type 2 diabetes, certain types of cancer, and even lower total mortality. In addition to some carotenoids constituting vitamin A precursors, they are implicated in potential antioxidant effects and pathways related to inflammation and oxidative stress, including transcription factors such as nuclear factor κB and nuclear factor erythroid 2-related factor 2. Carotenoids and metabolites may also interact with nuclear receptors, mainly retinoic acid receptor/retinoid X receptor and peroxisome proliferator-activated receptors, which play a role in the immune system and cellular differentiation. Therefore, a large number of downstream targets are likely influenced by carotenoids, including but not limited to genes and proteins implicated in oxidative stress and inflammation, antioxidation, and cellular differentiation processes. Furthermore, recent studies also propose an association between carotenoid intake and gut microbiota. While all these endpoints could be individually assessed, a more complete/integrative way to determine a multitude of health-related aspects of carotenoids includes (multi)omics-related techniques, especially transcriptomics, proteomics, lipidomics, and metabolomics, as well as metagenomics, measured in a variety of biospecimens including plasma, urine, stool, white blood cells, or other tissue cellular extracts. In this review, we highlight the use of omics technologies to assess health-related effects of carotenoids in mammalian organisms and models.

Abstract
The synthesis of the neuropeptide precursor proenkephalin was measured in bovine adrenal chromaffin cells following radiolabeling with [35S]methionine. Treatment of chromaffin cells with pertussis toxin (100 ng/ml) approximately doubled proenkephalin synthesis without altering total protein synthesis. Pertussis toxin pretreatment also increased proenkephalin synthesis in chromaffin cells exposed to vasoactive intestinal peptide (VIP) and 3-isobutyl-1-methylxanthine (IBMX). Combinations of IBMX plus nicotine, VIP, or histamine also synergistically enhanced proenkephalin synthesis, with no further elevation when the cells were also pretreated with pertussis toxin. The action of forskolin, a direct activator of adenylate cyclase, on proenkephalin synthesis was similarly potentiated by pertussis toxin or IBMX, presumably reflecting the abilities of both the toxin and this phosphodiesterase inhibitor to enhance the cyclic AMP response to forskolin. In contrast, increased synthesis of proenkephalin in response to phorbol esters was not affected by pertussis toxin treatment. These results suggest that pertussis toxin potentiates proenkephalin synthesis primarily through inactivation of guanine nucleotide-binding proteins that inhibit adenylate cyclase, although other signaling pathways may also be involved.

Abstract
Vasoactive intestinal peptide (VIP) evokes little or no secretion of catecholamines from cultured bovine chromaffin cells. However, pretreatment of chromaffin cells with pertussis toxin (PTX, 100 ng/ml for > or = 4 h) revealed that VIP is a secretagogue. In PTX-treated cells catecholamine secretion evoked by VIP occurs with minimal elevation of cyclic AMP and is only slightly enhanced by cyclic nucleotide phosphodiesterase inhibitors. Forskolin, a direct activator of adenylate cyclase, causes delayed secretion of catecholamines from chromaffin cells treated with PTX, but only with pronounced elevation of cyclic AMP levels. Stimulation of catecholamine secretion by histamine, known to activate phosphatidylinositol-specific phospholipase C in chromaffin cells, is also enhanced by preincubation of the cells with PTX. These results suggest that in the bovine chromaffin cell a PTX-sensitive G-protein mediates tonic inhibition of secretion, possibly by preventing activation of phospholipase C.

Abstract
To elucidate the possible involvement of GTP-binding proteins (G proteins) in the mechanism of exocytosis, we studied effects of pertussis toxin (PTX), guanosine 5'-O-(3-thiotriphosphate) (GTP-gamma-S), and antibodies against the G proteins (Gi and G(o)) on the secretory function of bovine adrenal chromaffin cells. Pretreatment of chromaffin cells with PTX resulted in an increase in acetylcholine-evoked catecholamine release. High K(+)-, histamine-, or gamma-aminobutyric acid-evoked catecholamine release was also potentiated by PTX pretreatment. The concentration of extracellular Ca2+ required for maximal release by 10(-4) M acetylcholine was decreased significantly in PTX-treated cells. In digitonin-permeabilized cells, PTX pretreatment resulted in a decrease of the half-maximal concentration (Km) of Ca2+ required for exocytosis with no significant change in the maximal stimulation (Vmax). Exposure of permeabilized cells to GTP-gamma-S (a nonhydrolyzable GTP analogue) inhibited Ca(2+)-dependent exocytosis by reducing the affinity for Ca2+. The effects of PTX pretreatment were mimicked by treatment of permeabilized cells with polyclonal antibodies selective for the alpha subunit of the PTX-sensitive G protein, G(o). Treatment with similar antibodies against the alpha subunit of Gi had no effect. These findings suggest that G(o) directly controls the Ca(2+)-triggered process in the machinery of exocytosis by lowering the affinity of the unknown target for Ca2+.

Abstract
Histamine activation of H1 receptors stimulates 3H release from cultured bovine adrenal chromaffin cells preloaded with [3H]noradrenaline. The initial (1-min) release induced by a high concentration of histamine was unaffected by the removal of extracellular Ca2+, whereas the more sustained response (10 min) was largely inhibited. In contrast, release induced by nicotine was dependent on extracellular Ca2+ at all times. The protein kinase inhibitor staurosporine inhibited both the initial and sustained (10-min) phases of histamine-induced release (IC50 in the region of 200 nM) but was ineffective against a direct depolarizing stimulus (56 mM K+). In contrast, the calmodulin antagonist trifluoperazine was equally effective against both stimuli. These data indicate that although a staurosporine-sensitive event (perhaps involving protein kinase C) is essential for coupling histamine receptor activation to the release processes, it is not essential for exocytosis itself. A further distinction between histamine- and depolarization-induced release was demonstrated by the differential effect of the guanine nucleotide-binding protein inhibitor pertussis toxin. Pretreatment with pertussis toxin (0.1 microgram/ml for 16 h) enhanced depolarization-induced release by approximately 1.5-fold. This pertussis toxin pretreatment was, however, approximately twofold as effective in potentiating histamine-evoked release. Thus, the characteristics of the histaminergic response are distinct from those of a depolarizing stimulus, perhaps indicating the involvement of different mechanisms in the release process.

Abstract
We have previously shown that pertussis toxin (PTX) stimulates delayed-onset, [Ca2+]o-dependent catecholamine (CA) release from bovine chromaffin cells. We now show that this effect of PTX is inhibited in part (50%) by dihydropyridine Ca(2+)-channel antagonists niludipine and nifedipine, and is potentiated by the dihydropyridine Ca(2+)-channel agonist Bay K-8644. We and others have shown that pretreatment of chromaffin cells with PTX results in enhanced catecholamine secretion in response to high [K+]o, nicotine and muscarine, and here we extend these observations by showing that toxin pretreatment also enhances the secretory response to [Ba2+]o. All these data are consistent with the concept that PTX may act on Ca2+ channels. To examine the possibility of a direct action of the toxin on the voltage-gated L-type Ca2+ channel known to be present in these cells, we studied the effects of the toxin on whole cell Ca2+ currents. We found and report here that spontaneous electrical activity was considerably increased in PTX-treated cells. Our measurements of whole cell inward Ca2+ currents indicate that the underlying mechanism is a marked shift of the activation curve of the L-type Ca2+ current along the voltage axis towards more negative potentials. While treatment of the cells with PTX had no effect on L-type Ca(2+)-channel conductance (6 nS/cell at 2.6 mM [Ca2+]o). PTX evoked the activation of a new class of Ca(2+)-selective channels (5 pS in 25 mM [Ca2+]pipet), which are rather insensitive to membrane potential.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The role of GTP-binding proteins (G-proteins) in the secretory process in chromaffin cells was investigated by studying the effects of pertussis toxin (PTX) on catecholamine release and generation of various second messengers. PTX was found to stimulate the catecholamine secretion induced by nicotine, 59 mM-K+ or veratridine. PTX also potentiated Ca2(+)-evoked catecholamine release from permeabilized chromaffin cells, suggesting that PTX substrate(s) regulate the exocytotic machinery at a step distal to the rise in intracellular Ca2+. We have investigated the possible intracellular pathways involved in the stimulation of secretion by PTX. PTX did not modify the translocation of protein kinase C (PKC) to membranes in intact or permeabilized cells; in addition, neither inhibitors nor activators of PKC had any effect on catecholamine release induced by PTX. Thus it seems unlikely that the effect of PTX on secretion is mediated by activation of PKC. The effect of PTX is also cyclic AMP-independent, as PTX did not change cytoplasmic cyclic AMP levels. The relationship between PTX treatment and arachidonic acid release was also examined. We found that an increase in cytoplasmic arachidonic acid concentration enhanced Ca2(+)-evoked catecholamine release in permeabilized cells, but arachidonic acid did not mimic the effect of PTX on the Ca2(+)-dose-response curve for secretion. Furthermore, PTX did not significantly modify the release of arachidonic acid measured in resting or stimulated chromaffin cells, suggesting that the stimulatory effect of PTX on secretion is not mediated by an activation of phospholipase A2. Taken together, these results suggest that PTX may modulate the intracellular machinery of secretion at a step distal to the generation of second messengers. In alpha-toxin-permeabilized cells, full retention of the PTX-induced activation of secretion was observed even 30 min after permeabilization. In contrast, when chromaffin cells were permeabilized with streptolysin-O (SLO), there was a marked progressive loss of the PTX effect. We found that SLO caused the rapid leakage of three G-protein alpha-subunits which are specifically ADP-ribosylated by PTX. We propose that a PTX-sensitive G-protein may play an inhibitory role in the final stages of the Ca2(+)-evoked secretory process in chromaffin cells.

Abstract
Formation of inositol polyphosphates has been characterized in cultured bovine adrenal chromaffin cells in terms of calcium dependency and isomers of inositol polyphosphates. There are two distinct pathways of generation of InsP3. Stimulants such as high K+ induce InsP3 accumulation by a calcium uptake-dependent mechanism. Stimulants such as Ang II induce InsP3 accumulation by a calcium uptake-independent mechanism. Both mechanisms are involved in nicotinic stimulation. These results suggest that calcium entry as well as receptor-mediated mechanisms play a significant role in phosphoinositides hydrolysis through phospholipase C in adrenal chromaffin cells. Nicotinic receptor stimulation induces a rapid and transient increase in Ins(1,4,5)P3 accumulation followed by a slower accumulation of Ins(1,3,4)P3. Moreover, nicotine induces a large and rapid increase in Ins(1,3,4,5,6)P5 accumulation with an extent and time course similar to Ins(1,4,5)P3, which peaks at 15 sec after stimulation. Nicotine also induced Ins(1,3,4,5)P4 and InsP6 accumulation with a slower time course and a lesser magnitude than Ins(1,3,4,5,6)P5. These results indicate that adrenal chromaffin cells possess fine regulation of inositol polyphosphates metabolism and that inositol polyphosphates are involved with the control of cellular function in these cells.

Abstract
Pertussis toxin stimulates both basal and nicotine-evoked catecholamine secretion from intact bovine adrenal chromaffin cells, as well as Ca2(+)-evoked release from permeabilized cells. Tetanus toxin inhibits all these effects; it reduces the secretion of intact cells treated with pertussis toxin to the basal level, and decreases by about 50% Ca2(+)-evoked release from permeabilized cells whether or not previously stimulated by pertussis toxin.

Abstract
Effects of pertussis toxin (islet-activating protein, IAP) on the secretory function of bovine adrenal chromaffin cells in culture were studied. Treatment of chromaffin cells with IAP resulted in an increase in both basal release of catecholamine and evoked-release by either acetylcholine (ACh) or high K+. In the dose-response curve for ACh-evoked release, IAP treatment produced an increase of the maximal response without affecting the half-maximal concentration of ACh. When the cells were permeabilized with digitonin after IAP-pretreatment, Ca2(+)-dependent exocytosis was markedly increased where the affinity of exocytosis for Ca2+ was augmented. These findings suggest that IAP-sensitive GTP-binding protein (or proteins) directory controls the Ca2(+)-triggered process in the machinery of exocytosis by modulating the affinity for Ca2+ of its unknown target.

Abstract
When [3H]inositol-prelabeled cultured bovine adrenal chromaffin cells were stimulated with nicotine (10 microM), a large and transient increase in [3H]inositol pentakisphosphate (InsP5) accumulation was observed. The accumulation reached the maximum level at 15 s, then declined to the basal level at 2 min. Nicotine also induced [3H]inositol tetrakisphosphate (InsP4) and [3H]inositol hexakisphosphate (InsP6) accumulation with a slower time course and a lesser magnitude than [3H]InsP5. The peaks of [3H]InsP4, [3H]InsP5 and [3H]InsP6 coincided with those of 32P radioactivity, when cells were doubly labeled with [3H]inositol and inorganic 32P. These results suggest that inositol pentakisphosphate is rapidly increased by nicotine, a cholinergic agonist, in cultured adrenal chromaffin cells.

Abstract
Release of catecholamines from bovine adrenal chromaffin cells exposed to mastoparan, a wasp venom peptide which activates GTP-binding proteins and phospholipase A2, was evaluated. Release of catecholamines was dependent on mastoparan concentration and time of exposure. This release was, however, independent of extracellular calcium and accompanied by release of the cytoplasmic marker lactate dehydrogenase. Mastoparan also inhibited catecholamine secretion evoked by nicotine, but the peptide had little or no effect on release induced by other secretagogues. These findings suggest that in chromaffin cells mastoparan is not a secretagogue but rather causes cell lysis and blocks nicotinic receptor function.
