Methacholine, nicotine and succinylcholine stimulated the phospholipase A2-acylation system of synaptic membranes isolated from the cerebral cortex of guinea pig. Stimulation by acetylcholine was partially blocked by atropine and by D-tuberocurarine respectively, indicating both muscarinic and nicotinic stimulation. Muscarinic stimulation by acetylcholine was greater than -isotinic stimulation, and stimulation by acetylcholine was completely blocked by a combip, or;. and n-tuberocurarine. The phospholipase A2-acylat tem was stimulated by phenylcphrine., id. Cqxoterenoi. Stimulation by noradrenaline was J-. tidlr, by phenoxybenzamine and pindalol i:spectively, indicating both 8-adrenergic and P-adrenergic ztimulation. n-Adrenergic stimulation by noradrenaline was greater than P-adrenergic-stimulation. 5 -mlation by noradrenaline was completely blocked by a combination of phenoxybenzamins and pindalol. Stimulation of both acylation and phospholipid hydrolysis, by 5-hydroxytryptamine and histamine were partially blocked by methysergide and diphenhydramine respectively. Stimulation by dopamine was blocked by halopcridol. Stimulation by y-aminobutyric acid was partially blocked by strychnine and by picrotoxin. Dichloroisoproterenol, atropine, methysergidr, diphenhydramine, strychnine, picrotoxin and eserine, at relatively high concentrations (1 mM), stimuhted the phospholipase A2-acylation system. Synergistic stimulations of both acylatior, and hydrolysis of phosphatidylcholine, were observed by adenosine combined with noradrenaline, 5-hydroxytryptamine, histamine, dopamine or yaminobutyric acid, respectively. In the presence of ATP-MgCI, synergistic stimulations of the hydrolysis of phosphatidyicholine were observed after 30 s by noradrenaline combined with 5-hydroxytryptamine, histamine, dopamine, aminobutyric acid or carbamoylcholine respectively. In the presence of GTP-MgC12 synergistic stimulations were obtained by cdrbamoylcholine combined with noradrenaline. 5-hydroxytryptamine. histamine, dopamine or y-aminobutyric acid, respectively. In the presence of ATP-MgC12 plus GTP-MgC12, stimulation by noradrenaline and one other agonist including 5-hydroxytryptamine, histamine, dopamine, y-aminobutyric acid or carbamoylcholine were close to additive. 相似文献

The sensitivities of apoptosis induced by E1A, c-Myc, Bax, and Nip3 to wild-type (wt) and mutated p53 and Id proteins were analyzed by transient transfection followed by flow cytometry with p53 null mouse cerebellum cell lines W7 and M13 that express wt and mutated p53 in response to dexamethasone, respectively. Apoptosis induced by c-Myc was stimulated weakly by wt p53, strongly by Ids, but suppressed completely by mutated p53 irrespective of coexpression with Ids, while apoptosis induced by E1A was suppressed by mutated p53 but stimulated when coexpressed with Ids. Apoptosis induced by Bax was little affected by wt and mutated p53, but inhibited by Ids, while apoptosis induced by Nip3 was inhibited by both wt and mutated p53 and inhibition was stimulated by Ids. Caspase-1 was activated only by Bax significantly when coexpressed with mutated p53 but not with wt p53. These results indicate that the apoptotic processes elicited by these inducers are different and differently affected by wt and mutated p53 and by Ids. 相似文献

Previous studies have demonstrated that metallothionein functions as an antioxidant that protects against oxidative DNA, protein, and lipid damage induced by superoxide anion, hydrogen peroxide, hydroxyl radical, and nitric oxide. The present study was undertaken to test the hypothesis that metallothionein also protects from DNA and lipoprotein damage induced by peroxynitrite, an important reactive nitrogen species that causes a diversity of pathological processes. A cell-free system was used. DNA damage was detected by the mobility of plasmid DNA in electrophoresis. Oxidation of low density lipoprotein was measured by a thiobarbituric acid-reactive substance, which was confirmed by lipid hydroperoxide assay. Plasmid DNA damage and low density lipoprotein oxidation were induced by 3-morpholinosydnomine, which produces peroxynitrite through the reaction between nitric oxide and superoxide anion or by synthesized peroxynitrite directly. DNA damage by 3-morpholinosydnomine was prevented by both metallothionein and superoxide dismutase, whereas the damage caused by peroxynitrite was prevented by metallothionein only. The oxidation of low density lipoprotein by 3-morpholinosydnomine and peroxynitrite was also significantly inhibited by metallothionein. This study thus demonstrates that metallothionein may react directly with peroxynitrite to prevent DNA and lipoprotein damage induced by this pathological reactive nitrogen species. 相似文献

The mechanism of metallothionein (MT) induction of the liver by endotoxin, which is mediated by a factor secreted by endotoxin-stimulated macrophages, was studied in vitro. MT induction of the liver cells by the endotoxin-stimulated macrophage conditioned medium was inhibited by a monoclonal antiepidermal growth factor (EGF) / transforming growth factor-alpha (TGF-alpha) receptor antibody, which acts as an antagonist of EGF and TGF-alpha. MT was induced by the substance, which was adsorbed by polyclonal antibody to TGF-alpha, but not by a monoclonal antibody to EGF, in the conditioned medium of endotoxin-stimulated macrophages. These results suggest that TGF-alpha secreted by macrophages is involved in MT induction by endotoxin. 相似文献

Inducible binding proteins for C4-dicarboxylic acids (DBP) and glucose (GBP) were isolated from Pseudomonas aeruginosa by extraction of exponential-phase cells with 0.2 M MgC12 (pH 8.5) and by an osmotic shock procedure without affecting cell viability. DBP synthesis was induced by growth on aspartate, alpha-ketoglutarate, succinate, fumarate, malate, and malonate but not by growth on acetate, citrate, pyruvate, or glucose. Binding of succinate by DBP was competitively inhibited by 10-fold concentrations of fumarate and malate but not by a variety of related substances. GBP synthesis and transport of methyl alpha-glucoside by whole cells were induced by growth on glucose or pyruvate plus galactose, 2-deoxyglucose, or methyl alpha-glucoside but not by growth on gluconate, succinate, acetate, or pyruvate. The binding of radioactive glucose by GBP was significantly inhibited by 10-fold concentrations of glucose, galactose, and glucose-1-phosphate but not by the other carbohydrates tested. The binding of glucose by GBP or succinate by DBP did not result in any chemical alteration of the substrates. 相似文献

We examined by using 2,2′-azobis(2-amidinopropane) dihydrochloride (AAPH) as a radical generator the ability of estrogens to scavenge carbon-centered and peroxyl radicals. Electron spin resonance signals of carbon-centered radicals from AAPH were diminished by catecholestrogens but not by phenolic estrogens, showing that catecholestrogens efficiently scavenged carbon-centered radicals. However, fluorescent decomposition of R-phycoerythrin by AAPH-derived peroxyl radicals was inhibited by catecholestrogens and phenolic estrogens. Evidently, peroxyl radicals were scavenged by catecholestrogens and by phenolic estrogens. However, the scavenging ability of 4-hydroxyestradiol was less than 2-hydroxyestradiol. Strand break of DNA induced by AAPH was inhibited by catecholestrogens, but not by phenolic estrogens under aerobic and anaerobic conditions. Inactivation of lysozyme induced by AAPH was completely blocked by 2-hydroxyestradiol under aerobic and anaerobic conditions, and by 4-hyroxyestradiol only under anaerobic conditions. Peroxidation of arachidonic acid by AAPH was strongly inhibited by catecholestrogens at low concentrations. Only large amounts of phenolic estrogens markedly inhibited lipid peroxidation. These results show that catecholestrogens were antioxidant against AAPH-induced damage to biological molecules through scavenging both carbon-centered and peroxyl radicals, but phenolic estrogens partially inhibited AAPH-induced damage because they scavenged only peroxyl radicals. 相似文献

Intact cells of the marine bacterium Alteromonas haloplanktis 214 oxidized NADH, added to the suspending medium, by a process which was stimulated by Na+ or Li+ but not K+. Toluene-treated cells oxidized NADH at three times the rate of untreated cells by a mechanism activated by Na+ but not by Li+ or K+. In the latter reaction, K+ spared the requirement for Na+. Intact cells of A. haloplanktis oxidized ethanol by a mechanism stimulated by either Na+ or Li+. The uptake of alpha-aminoisobutyric acid by intact cells of A. haloplanktis in the presence of either NADH or ethanol as an oxidizable substrate required Na+, and neither Li+ nor K+ could replace it. The results indicate that exogenous and endogenous NADH and ethanol are oxidized by A. haloplanktis by processes distinguishable from one another by their requirements for alkali metal ions and from the ion requirements for membrane transport. Intact cells of Vibrio natriegens and Photobacterium phosphoreum oxidized NADH, added externally, by an Na+-activated process, and intact cells of Vibrio fischeri oxidized NADH, added externally, by a K+-activated process. Toluene treatment caused the cells of all three organisms to oxidize NADH at much faster rates than untreated cells by mechanisms which were activated by Na+ and spared by K+. 相似文献

Effect of acetaldehyde and cyanamide on the metabolism of formaldehyde by hepatocytes, mitochondria, and soluble supernatant from rat liver 总被引:1,自引:0,他引:1
Formaldehyde can be metabolized primarily by two different pathways, one involving oxidation by the low-Km mitochondrial aldehyde dehydrogenase, the other involving a specific, glutathione-dependent, formaldehyde dehydrogenase. To estimate the roles played by each enzyme in formaldehyde metabolism by rat hepatocytes, experiments with acetaldehyde and cyanamide, a potent inhibitor of the low-Km aldehyde dehydrogenase were carried out. The glutathione-dependent oxidation of formaldehyde by 100,000g rat liver supernatant fractions was not affected by either acetaldehyde or by cyanamide. By contrast, the uptake of formaldehyde by intact mitochondria was inhibited 75 to 90% by cyanamide. Acetaldehyde inhibited the uptake of formaldehyde by mitochondria in a competitive fashion. Formaldehyde was a weak inhibitor of the oxidation of acetaldehyde by mitochondria, suggesting that, relative to formaldehyde, acetaldehyde was a preferred substrate. In isolated hepatocytes, cyanamide, which inhibited the oxidation of acetaldehyde by 75 to 90%, produced only 30 to 50% inhibition of formaldehyde uptake by cells as well as of the production of 14CO2 and of formate from [14C]formaldehyde. The extent of inhibition by cyanamide was the same as that produced by acetaldehyde (30-40%). In the presence of cyanamide, acetaldehyde was no longer inhibitory, suggesting that acetaldehyde and cyanamide may act at the same site(s) and inhibit the same formaldehyde-oxidizing enzyme system. These results suggest that, in rat hepatocytes, formaldehyde is oxidized by cyanamide- and acetaldehyde-sensitive (low-Km aldehyde dehydrogenase) and insensitive (formaldehyde dehydrogenase) reactions, and that both enzymes appear to contribute about equally toward the overall metabolism of formaldehyde. 相似文献
