Regulation of the plasma membrane Ca2+ pump by cyclic nucleotides in cultured vascular smooth muscle cells.
We investigated the mechanisms of Ca2+ extrusion from cultured rat aortic smooth muscle cells while monitoring changes in the cytosolic Ca2+ concentration ([Ca2+]i) using fura 2 fluorescence. 45Ca2+ efflux from these cells consisted of two major mechanisms; one was dependent on the extracellular sodium concentration (Na+o) and the other was independent of Na+o. Na+o-dependent efflux increased m...
متن کاملEffects of atrial natriuretic factor and vasopressin on cyclic nucleotides in cultured kidney cells.
The cellular mechanism of the action of atrial natriuretic factor (ANF) is thought to involve activation of guanylate cyclase. Increasing evidence shows a direct tubular effect of ANF. Part of the ANF-induced diuresis has been suggested to be due to inhibition of the action of arginine vasopressin (AVP) in the cortical collecting tubule. In this study we investigated the effect of ANF on cyclic...

متن کاملInteraction of glucocorticoid hormones and cyclic nucleotides in induction of tyrosine aminotransferase in cultured hepatoma cells.
Reproducible induction of the enzyme tyrosine aminotransferase by dibutyryl cAMP (Bt2cAMP) in a line of HTC hepatoma cells in suspension culture requires that the cells be preinduced with dexamethasone, a synthetic glucocorticoid which itself induces tyrosine aminotransferase. Concentrations of dexamethasone that do not induce tyrosine aminotransferase fail to support Bt2cAMP induction, removal...
متن کاملEffect of interferon on concentrations of cyclic nucleotides in cultured cells.
Constant intracellular concentrations of both adenosine 3',5'-cyclic-monophosphate (cyclic AMP) and guanosine 3',5'-cyclic-monophosphate (cyclic GMP) were obtained when leukemia L1210 cells were cultivated under steady-state conditions in the chemostat. In this sensitive and controlled system addition of mouse interferon resulted in a rapid (5-10 min) increase in the intracellular concentration...
