Catecholamine-induced transport systems in trout erythrocyte. Na+/H+ countertransport or NaCl cotransport?
It has previously been shown (Baroin, A., F. Garcia-Romeu, T. Lamarre, and R. Motais. 1984a, b. Journal of Physiology. 350:137, 356:21; Mahé, Y., F. Garcia-Romeu, and R. Motais. 1985. European Journal of Pharmacology. 116:199) that the addition of catecholamines to an isotonic suspension of nucleated red blood cells of the rainbow trout first stimulates a cAMP-dependent, amiloride-sensitive Na+...
متن کاملSteady-state kinetics of catecholamine transport by chromaffin-granule "ghosts".
Resealed chromaffin-granule ;ghosts' were used to study the steady-state kinetics of catecholamine transport. The pump has a high affinity for (-)-noradrenaline, (-)-adrenaline, tyramine and 5-hydroxytryptamine (serotonin), but a lower affinity for (+)-noradrenaline. The measured rates of incorporation do not conform to Michaelis-Menten kinetics, but affinity constants for the former substrates...
متن کاملGenotype and vascular phenotype linked by catecholamine systems.
In this issue of Circulation, Fung and coworkers1 report associations between hand venous responses to the indirectly acting sympathomimetic amine tyramine and single nucleotide polymorphisms (SNPs) of genes encoding particular proteins related to the synthesis, release, reuptake, and metabolism of catecholamines. The importance of these associations lies in their illustrating how genotypic dif...
متن کاملThe effect of nicotine on developing brain catecholamine systems.
Biochemical studies have confirmed that nicotinic acetylcholine receptor mRNA and protein are expressed early in the development of the fetal central nervous system. Perinatal administration of nicotine produces a broad spectrum of effects on brain development, including inhibition of DNA synthesis, altered ornithine decarboxylase activity, altered neurotransmitter function, and significant alt...
متن کاملIndividual differences in non-regulatory ingestive behavior and catecholamine systems.
Animals that eat and/or drink in response to electrical stimulation of the lateral hypothalamus (ESLH-pos) are more responsive to both schedule-induced polydipsia (SIP) tests and a series of amphetamine (AMPH) injections than animals that do not exhibit these behaviors (ESLH-neg). Moreover, prior exposure to the behaviorally activating SIP experience, or to AMPH, permanently transformed the ESL...
