(4) The distribution of PKC returned to control values by 24 h. High glucose did not stimulate phosphoinositide hydrolysis, as evidenced by the absence of an increase in the water-soluble inositol phosphates, indicating that DAG was not generated through the action of a phosphoinositide-specific phospholipase C. Cells treated with the cell-permeable DAG analogue 1-oleoyl-2-acetyl glycerol to activate PKC displayed approximately two-fold increases of fibronectin, laminin, and type IV collagen mRNA levels after normalization against actin.

(6) Concomitantly, an increase of inositol phosphates and diacylglycerol (DAG) production was observed.
(7) The accumulation of [14C]C20:4-DAG (lower in ET than in saline-infused rats) was paralleled by a decrease in phosphatidylinositol (PI) labelling, whereas phosphatidic acid showed a transient increase by 5 min in saline- but not in ET-infused rats.
(8) To determine the role of the DAG produced upon bombesin stimulation, we examined the effects of another activator of protein kinase C, the phorbol ester 12-O-tetradecanoylphorbol 13-acetate (TPA).
(9) It is concluded that carbachol increases [Ca2+]i by facilitating Ca2+ entry through L-type Ca2+ channels via a 1,2-diacylglycerol (DAG)-protein kinase C (PKC)-dependent pathway while quisqualate mobilizes Ca2+ from inositol 1,4,5-trisphosphate (IP3)-sensitive stores.
(10) In order to characterize the properties of the glyceroglycolipid membranes, ESR spectroscopic studies were carried out with an acyl spin-labeled galactosyl ceramide (SL-GC) or a headgroup spin-labeled phospholipid (SL-6-DPPA) in 1,2-dipalmitoyl[beta-cellobiosyl-(1'---3)]glycerol (Cel-DAG) liposomal membranes.
(11) The E. coli dgkA locus which contains the coding sequences for DAG kinase was subcloned into an eukaryotic expression vector, pMT2.
(12) The mean residence time for pharmacologically active molecules in the body was six times shorter for DAG (1.9 hr) than for DBD (11.4 hr).
(13) These data suggest that PKC is a mediator in the generation of DAG.
(14) These results suggest that DAG accumulation is involved in the potentiating effect of A23187 on CCh-stimulated amylase secretion.
(15) It is concluded that insulin-dependent PDH activation, PIG hydrolysis, and IG and DAG generation are mediated by the wild-type but not by the mutated insulin receptor of Val996.
(16) Since most alloantibodies detected only by 2SP-IAT or LISS-DAG were of doubtful clinical significance, and these techniques produced a high number of unwanted positive reactivities, we conclude that 2SP-IAT and LISS-DAG are not appropriate for the pretransfusion screening for unexpected antibodies.
(17) 261, 8597-8600), lipase from Rhizopus arrhizus selectively degraded the 1-acyl-containing species (DAG), but the ether lipid (EAG) was resistant and was identified and quantified after thin layer chromatography separation.
(18) 1-Oleoyl-2-acetylglycerol, a synthetic DAG analog, stimulated endothelial cell DNA synthesis in a concentration-dependent manner.
(19) Whereas DPG and DS are stable at physiological pH, DAG is unstable, undergoing hydrolysis (regeneration of DF) and rearrangement (intramolecular acyl migration to the 2-, 3- and 4-O-acyl-positional isomers).
(20) Addition of PRL to hepatocyte cultures significantly increased [3H]-glycerol incorporation into DAG within 5 minutes which was followed by a loss of cytosolic PKC activity by 10 minutes.

(2) The combined immediate and delayed responses to fleas in the dog are as observed by other investigators in man and guinea pigs.
(3) In dogs, cibenzoline given i.v., had no effects on the slow response systems, probably because of sympathetic nervous system intervention since the class 4 effects of cibenzoline appeared after beta-adrenoceptor blockade.
(4) It was shown in experiments on four dogs by the conditioned method that the period of recovery of conditioned activity after one hour ether anaesthesia tested 7 to 7.5 days.
(5) Dialysis of dog plasma against an artificial c.s.f.
(6) For similar inotropic responses, normo- and hyperkalaemic dogs had similar levels of (Na+, K+)-ATPase inhibition and microsomal-bound digoxin.
(7) Complete heart block was produced in 20 of 20 dogs.
(8) The dog and the pig also have an endoperoxide-sensitive constrictor system activated by the 11,9-(epoxymethano) analogue of PGH2 and, of particular note, ICI 79939 and its 11-oxo analogue.
(9) All of this in the same tones of weary nonchalance you might use to stop the dog nosing around in the bin.
