Chloride channels -- Research ,Cyclic adenylic acid -- Physiological aspects ,Biological sciences - Abstract
Research suggests that beta-adrenoceptor-linked stimulatory guanosine nucleotide-binding protein stimulates cyclic-adenosine monophosphate-dependent chloride channel activity in guinea pig atrial cardiomycocyte cells. Experiments using the beta-adrenoceptor stimulant biochemicals isoproterenol and adenylyl-cyclase are described.

Knowledge advancement has had minimal impact on increasing understanding of the properties and modulation of muscle calcium (Ca) channels. Molecular activity which condition gating and modal switching, and channel pore structure and characteristics, need to be identified. In addition, further biochemical studies must be done to examine intracellular enzymatic pathways, determine G protein subunit specificity and specify the molecular nature of receptor-G protein interaction.

We compared the effects of cytosolic free magnesium ([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]) on L-type [Ca.sup.2+] current ([I.sub.Ca,L]) in patch-clamped guinea pig ventricular cardiomyocytes under basal conditions, after inhibition of protein phosphorylation, and after stimulation of cAMP-mediated phosphorylation. Basal [I.sub.Ca,L] density displayed a bimodal dependence on the concentration of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] ([[Mg.sup.2+]].sub.i]]; [10.sup.-6]-[10.sup.-2] M), which changed significantly as cell dialysis progressed due to a pronounced and long-lasting rundown of [I.sub.Ca,L] in low-[Mg.sup.2+] dialysates. Ten minutes after patch breakthrough, [I.sub.Ca,L] density (at +10 reV) in [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]-depleted cells [[Mg.sup.2+]][sub.i] ~1 [micro] M) was elevated, increased to a maximum at ~20 [micro] M [[Mg.sup.2+]][sub.i], and declined steeply at higher [[Mg.sup.2+]][sub.i]. Treatment with the broad-spectrum protein kinase inhibitor K252a (10 [micro] M) reduced [I.sub.Ca,L] density and abolished these effects of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] except for a negative shift of [I.sub.Ca,L]-voltage relations with increasing [[Mg.sup.2+]][sub.i]. Maximal stimulation of cAMP-mediated phosphorylation occluded the [Mg.sup.2+.sub.i]-induced stimulation of [I.sub.Ca,L] and prevented inhibitory effects of the ion at [[Mg.sup.2+]][sub.i] [is less than] 1 mM but not at higher concentrations. These results show that the modulation of [I.sub.Ca,L] by [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] requires protein kinase activity and likely originates from interactions of the ion with proteins involved in the regulation of protein phosphorylation/dephosphorylation. Stimulatory effects of [Mg.sup.2+.sub i] on [I.sub.Ca,L] seem to increase the cAMP-mediated phosphorylation of [Ca.sup.2+] channels, whereas inhibitory effects of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] appear to curtail and/or reverse cAMP-mediated phosphorylation. whole cell patch-clamp recording; guinea pig ventricular cardiomyocytes; cAMP signaling

GUANOSINE triphosphatase - Abstract
Presents a study which was conducted to further characterize the role of guanosine nucleotide-binding protein (Gs) in Ionic current (IC1) regulation. Materials and methods used; Effect of isoproterenol (ISso) and forskolin on holding current in guinea pig ventricular myocytes; Discussion on the study.
